The head unit quit working around 98k. The head unit is the radio, and screen which includes the back up camera. From what we have been told and find online, this is a known problem with them and affects other models as well. For the most part the head unit doesn't work but once in a while, once a month, it comes on but shows the Chevy logo on the screen which is odd because it is a GMC. Once you turn the car off, it will be gone again until it decides to come back. We took it into a dealer who tried to hook up to it and reprogram or update it, but he had no luck. Now we are without a backup camera that is a safety issue. I do not know why this isn't a recall as it is well known about issue.

Have had to replace the VVT solenoids several times within a year spam. Had to replace the rear main seal because it blew out due to carbon build up. Having issues with excessive oil consumption. Now the vehicle just started with: going from a stop position to accelerating at low speeds the vehicle stalls and dies. I want GM to take accountability and fix this issue as it is a safety issue to myself and everyone on the road.

Wiper blades transmission plastic parts keep popping or breaking this is the THIRD time this has happened at a cost of $350. Why would you use plastic parts for this knowing that it will break easily? Who can afford to keep replacing this? 12

The contact owns a 2017 GMC Terrain. The contact stated that after the vehicle was taken to a local car wash, while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the residence; however, the next day, the vehicle hesitated while starting. The message "Stabilizer - Power to Engine Reduced" was displayed. The vehicle was taken to a local independent mechanic, where it was diagnosed, and it was determined that the engine possibly needed to be replaced because the engine failed to turn over. The vehicle was towed to a local dealer, where it was diagnosed, and it was determined that the engine was blown. The contact was informed that the engine and the starter needed to be replaced. The vehicle was not repaired due to the cost and remained with the local dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 104,750. The VIN was not available.

I had a message flash that said the power to the engine was reduce. Next message said check stabilink ( or something similar).. it said drive with caution. I live 2 mins from my job I drove home and pulled in the driveway I then felt the car act like it wanted to shake. This was on 2-10-26 I contacted onstar asked them to run a diagnostic. The codes that came back P0016 p0089 p228D are very well known codes with many people with the same vehicle/engine that have had to replace the engine. The engines have known issues had I known that maybe I could have replaced a part or two or three or four to have a stable vehicle now my vehicle is currently at GMC DEALER since Tuesday morning actually had it towed there monday night. I called Wednesday evening they still wasn't sure the "issue". Thursday I wait until about 1pm spoke with John he said well we are pretty sure you need a new engine the mechanic is checking a few more things the car has no pressure. About a hr later I get a email and a call saying the timing chain skipped and something about the pistons and the valves and I need a new engine . John called me and said well.Ill tell you what we will offer you a brand new Engine for the same price as a rebuild plus you get 3yrs 300 thousand warranty for 10,944. Give or take a few dollars. We'll first I paid like 15,500 for the car that I just litetally paid off like Jan 12026. I really feel like had GMC Made buyers aware that the vehicle has defective parts/engines buyers could replace parts or GMC should be held accountable. I started googling the engine and found out that there is a class action lawsuit and a recall on " certain" 2017 terrains depending on the vin. Same issues my car is having but its saying my car has no recall.

Rear main seal blow out

On January 31, 2026, while driving on the highway, my 2017 GMC Terrain suddenly began shaking as if it was going to stall. Thankfully, I managed to exit the interstate before the vehicle lost power. Luckily, when this happened, it "only" blocked traffic on a side road. The Terrain was towed to my garage. The mechanic called to inform me that the vehicle was out of oil -even though it was not due for servicing, nor did a “check oil" warning appear. He noted that this was not the first time he had seen this problem occur with this particular make and model: the PCV valve had frozen due to recent cold weather, which led to the rear main seal fracturing, causing oil leaking. In addition, the manifold had also cracked. He explained that repairs would be costly given the labor needed to remove the transmission and perform other related tasks. He recommended that I "Google" the problem to gain an understanding of the time involved to complete this repair. My research corroborated that this was a very labor-intensive undertaking. More concerning was discovering an abundance of cases documenting this failure -as well as class action lawsuits- which underscores the fact that GM knows about this issue but refuses to address it. I am not sure why there hasn't been a recall—though perhaps that's a question for people much smarter than I am. Now, after spending thousands of dollars, I have a vehicle with an oil life monitoring system that doesn't function as intended—and worse, I know this could happen again.

Traveling on the expressway, engine made wearing noise, reduced engine power and complete engine failure while driving. Rear main seal blowout due to a defective PCV system freezing. It is a known issue for GM2.4L engine especially in cold weather leading to massive oil loss and catastrophic engine damage. This has been confirmed by a GM authorized dealer.

The PCV valve froze which caused pressure to build up in the rear main seal to fail. Causing oil to leak out of the motor. Hence the motor won't hold oil.

The contact owns a 2017 GMC Terrain. The contact stated that the vehicle failed to start. The vehicle was towed to an independent mechanic, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The vehicle was towed to the dealer, where the engine diagnostic result was confirmed. The vehicle was not repaired due to the cost. The contact stated that two years prior to the failure, the vehicle failed to accelerate as intended while depressing the accelerator pedal and the vehicle stalled. The manufacturer was not notified of the failure. The failure mileage was unknown.

I am filing this complaint to report a catastrophic engine failure involving my 2017 GMC Terrain equipped with the 2.4L Ecotec engine, which I believe is the result of a known manufacturing defect related to excessive oil consumption and premature internal engine wear. At approximately 88,000 miles, my vehicle experienced severe engine failure, including excessive oil consumption, timing chain failure, and complete engine failure, which has been confirmed in writing by a licensed repair facility. The shop determined that the engine failure was caused by oil starvation resulting from excessive oil consumption, leading to internal engine damage and timing chain failure. This failure occurred without warning and rendered the vehicle unsafe to operate. Sudden engine failure creates a serious safety risk, including loss of power while driving, inability to accelerate, and increased risk of collision. This engine failure matches a well-documented defect pattern involving General Motors’ 2.4L Ecotec engines, which have been the subject of class-action lawsuits, settlements, and jury verdicts related to premature piston ring wear, excessive oil consumption, and resulting engine damage or failure. These issues have been widely reported in Chevrolet Equinox and GMC Terrain vehicles within my model year range. My vehicle was properly maintained, and this failure was not the result of neglect, misuse, or normal wear and tear, but rather a latent manufacturing defect that manifested after the warranty period but well within the reasonable life expectancy of the engine. I am requesting that NHTSA formally document and investigate this defect, as it presents a significant safety concern for drivers operating vehicles equipped with this engine. I also request that General Motors be required to address this defect to prevent additional engine failures and potential safety incidents.

[XXX], our 2017 Terrain Denali displayed code: “Low Oil/Shut Engine Off” so had it towed to Laura Buick/GMC Colllinsville, IL. Laura confirmed the issue was blown rear seal due to design of intake cover and PCV. They checked with aftermarket warranty for VIN [XXX] , warranty contract number [XXX] who said it was not a covered issue. We called Warranty folks also and were told it was an “external issue” and not covered. Appealed to GM Customer Service who said VIN was not covered. The vehicle has approximately 83,000 miles and we referenced PIP5093B and Special Coverage Program number SB-10057977, and Special Coverage Adjustment 16118 Excessive Engine Oil Consumption.

This car burns 1 quart of 5w-30 synthetic blend oil every 200 miles! The pcv valve has been cleaned numerous times and this does not affect the burning oil issue and yes this can be inspected upon request. Safety put at risk you ask, this is a ticking timebomb ready to ruin the engine due to burning oil, leaves me stranded in my rural town for fear of mechanical breakdown, need to carry two 5 quart containers of oil, and dipstick needs to be checked every 100 miles. I have scheduled appt with GMC dealer in Chadron NE for mid January 2026. There are no warning lamps or messages that appear and this problem has been going on since August 2025, bought the car February 2025 from Chevy dealer in above mentioned town. KBB has a trade in value for this car at 1500 and private sale at 1900 for a 2017 Terrain SLT! Unbelievable!!!!!!

For a year we have had to check to the oil weekly and add oil due to the vehicle burning oil so quickly. The past month we have had to check it daily and add oil. We do regular routine oil changes and have had to get them before the next one is due. Recently when driving the “oil pressure low stop engine” light has been coming on almost daily. The oil change company has reported to us that it is due to the 2.4 Eco tech motor. You can smell the oil burning through the vents inside the car.

The power steering assembly failed and caught on fire. This then caused the engine to malfunction and no longer work. This happened while driving on the interstate at a speed of approximately 80mph. No prior check engine lights were visible

We have been keeping up with all maintenance and oil changes. We have only driven the car for less than a year. At time of oil change; the oil has been low, resulting in OVER oil consumption; Requiring an extra quart of oil to be added between oil changes. When we purchased the vehicle, there was an strong exhaust smell; The shop that we bought the vehicle stated there were no issues and we have taken it to them multiple times an hour away from our home. The car completely shut off while my minor son and I were driving. Placing both of our lives at risk! It would never start back up. Now the car has seized and requires an engine replacement. It is sitting at a local garage while we wait for the dealership to help us, to no avail.

I was driving back from out of state and all the sudden the engine just got loud. So I pulled over and check oil levels. Except there is no access to the transmission oil. The only way to check this is to remove the front driverside tire, take a bolt out and see if any oil drips out. This is insane that there is no dip stick. I am taking it to a mechanic on Monday but to not have quick access to this is wild.

Throttle position system all of a sudden went bad. My 2017 Terrain started shaking. I was holding up traffic. The sun couldn't go over 5mph. I've read online where this is happening alot in 2010'2017 GMC Terrains.

I looked up my recall on my vehicle about my headlights being recall. Never received any information there was a recall.

GM recently recalled over 500,000 car engines. The warning signs to look out for was a “knocking” sound coming from the engine. I had recently experienced the same issues that the recalled car engines were experiencing. I went to get it checked out and my mechanic said there were chunks of metal in the engine. The GM engine recall should include 2017 GMC TERRAINS SLT. If I had not got it looked at, it would have caused an accident that would have been unpreventable due to the warning signs of only the knocking sound. No other lights had came on in the car. Please consider putting this make and model in the engine recall! If someone reaches out to me, I have the name of my mechanic that can verify the engine issue of my GMC.

March 1, 2025, I was driving from Charlotte, NC east bound on highway 40 towards Wilmington and all of a sudden my car just stopped while I was in the left lane. I was able to cruise over to the right shoulder and park my car in front of a sign that read exit 298 a few feet ahead. From there I was on the highway about two hours trying to get a tow truck to tow my 2017 GMC Terrain to the nearest GMC dealership which so happened to be 10 miles away. Which the tow never came. My step father drove about 100 miles west to pick me and my daughters up. All night I was on the phone with one tow truck company after another and every one kept saying they couldn’t find my car. In the morning I called another tow and he was able to find my car in the same location I left it. It was a Sunday so I had to wait until Monday to follow up with GMC Thompson. They advised I needed engine work. I was told I needed, timing chains, compression, gear bolts. However my car had just been repaired in November 2024, because my car wouldn’t start up after work. GMC in Charlotte Liberty GMC they replaced the gasket, chains, pipes, pistons, bolts, screws, seals, valves, bearings, actuators, tensioners, manifold, I mean the engine was rebuilt basically. It Thompson GMC about month to repair the vehicle because they were waiting for parts. The last week Lisa my representative was able to get me a loner car. I’ve been driving the car for about almost 3 weeks and I’m still very Leary of it. Terrible experience and I don’t see any recalls for my year make and model but I believe I’m probably not the only one with this year make and model that has gone through this. There’s two dates so I’m not sure which date to put.

1st time - rear main seal blew out & engine lost all of its oil causing rocker arm to break & chains to slip-vehicle sputtered & DIED while driving down busy street & would not restart - my safety & safety of others driving behind me were at risk for causing a rear end accident and/or pile up crash - no warning lights or sounds alerted me - dealership told us General Motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in Midwest states due to colder temperatures - the intake manifold vent hole is not large enough to let air out, so it plugs up & causes pressure to blow out rear seal, which causes oil to leak out and engine dies. When replaced with a remanufactured engine intake manifold vent hole was not drilled out causing it to happen again 2nd time - when leaving parking spot at work noticed oil puddles underneath my vehicle, I checked my oil, it showed full, I was concerned, drove to nearby last place I got my oil change. They informed me that all the oil had leaked out and showed me the bottom of my vehicle oil covered the front to the back of my vehicle. They also said that I was extremely lucky to get to shop before engine blew and stopped dead. AGAIN my safety and safety of others behind me could have been a rear end accident and/or car pileup crash - again no warning lights or sounds alerted me - shop personal told me General Motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in Midwest states due to colder temperatures - even though the repairs where done by a certified dealership the first time they replaced with a remanufactured engine but failed to drill out the intake manifold vent hole bigger so this would not happen again BUT IT DID. General Motors cannot just sell vehicles it has to stand behind what they sell which in my case they have not. Due to GM lack of concern, recalls, reimbursements, lives have been and continue to be at risk

The contact owns a 2017 GMC Terrain. The contact stated while starting the vehicle, there was an abnormal sound coming from the engine, especially during colder mornings. The vehicle was taken to an independent mechanic, where it was diagnosed that the solenoids had failed and needed to be replaced. The vehicle was repaired. The contact stated that on a separate occasion, while driving 30 MPH, the vehicle stalled. The vehicle was towed to the residence. An independent mechanic diagnosed the vehicle at the residence and determined that the timing belt was damaged and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 85,000.

I am writing to formally express my dissatisfaction with my 2017 GMC Terrain, which has experienced severe engine failure due to excessive oil consumption. I purchased this vehicle with the expectation of reliability and durability, yet at only 80,000 miles, the engine seized without warning, rendering my vehicle completely inoperable. I have consistently maintained my Terrain according to the manufacturer’s recommended service schedule. However, I recently discovered that the engine was consuming oil at an alarming rate of 1 quart per 1,000 miles, which ultimately led to catastrophic failure. There were no warning lights or clear indicators of low oil, making it impossible for me to prevent the damage. After researching, I have found that numerous other GMC Terrain owners have reported similar excessive oil consumption issues, indicating a potential widespread defect in this engine design. As a loyal GM customer, I am extremely disappointed that a well-maintained vehicle would suffer such a failure at a relatively low mileage. Given the severity of this issue, I request that GM take responsibility for this defect by covering the full cost of engine repair or replacement. A vehicle should not require a complete engine overhaul at 80,000 miles due to a known design flaw. Please provide a prompt resolution to this matter. If GM is unwilling to address this issue, I will have no choice but to explore other options, including filing a complaint with the National Highway Traffic Safety Administration (NHTSA) and seeking legal counsel. I hope to resolve this matter amicably and look forward to your timely response.

Today is [XXX]. 3 days ago my infotainment system my plug-in lighter charger all of them that's in the vehicle and my rear windshield wiper and my blinkers all went out at the same time. I had a licensed mechanic that has the fuse Checker tool, checked every fuse that he can see under the hood and on the inside of the vehicle and all the fuses lit up. I then went to O'Reilly's Auto Parts here in Highland Park Michigan bought the Savannah long life two pack bulbs for the rear blinkers and they still did not work they would not come on the brake lights would not come on nothing comes on. I then told a gentleman named Frank at that O'Reilly's about the issue about how all those components went out at the same time and he said there was currently a recall about those issues on my year making model of my GMC Terrain which is a 2017 I cannot locate that recall. The only recall I can locate is the one that describes the high beam on the headlights and that is it. So I don't know where that recall is he's talking about I don't know anything about fixing cars I just need some answers. I'm hoping someone will be able to locate the recall that he's talking about so I can have my vehicle looked at and get the issue resolved.

As per several other complaints on the GMC terrain of particular years my vehicle has had a rear main seal leak, a blown engine terrible amounts of oil consumption and now the second engine has malfunctioned. And made the vehicle inoperable. The safety of myself and others was put at risk as the vehicle lost all power and cut off. The problem has had class action lawsuits filed. The first time the engine failed no warnings came on the second time a reduced engine power came on that we had no idea existed. The vehicle consumed oil very quickly, with in days the oil could need replaced. Oil consumption has been going on for years. Even after replacing engine.

DETAILS: Frozen/clogged PCV in the intake manifold caused the rear main seal to burst due to crankcase pressure, leading to complete engine failure. The 2.4 EcoTech engine must be entirely replaced. GMC refuses to act despite being well aware of this consistent issue. There is a class action lawsuit, service bulletins and multiple examples of this scenario all over the internet. RESOLUTION NEEDED ASAP. - 1/20/25: While driving home from my night shift at highway speeds, exhaust fumes entered the cabin, followed by a loud pop and sudden engine failure. The check engine light never came on and the vehicle would not restart. After towing to the dealership, they confirmed what occurred and noted that it happened on the coldest night of the year, consistent with the well-documented defect in the 2.4L EcoTech engine. They estimated replacement cost can run up to $10,000 and is my responsibility, advising that GM takes no liability for this known issue. This is not an isolated incident for this engine. GM is fully aware of this defect evidenced by multiple service bulletins, including TSB GMC 19-NA-021, which explicitly states this issue is known for ALL 2010-2017 GMC Terrains. Despite this when I called GM for a resolution, I was told my VIN is somehow excluded, making me ineligible for assistance. Instead of taking responsibility, GM directed me to NHTSA, claiming they alone can update affected VINs. This is NHTSA and GM’s failure, not mine. - This situation is completely unacceptable. GM must immediately resolve this issue in one of the following ways: 1. Full engine replacement at no cost to me. 2. Complete payoff of my remaining loan balance. Additionally, NHTSA must provide an explanation for why my VIN is not included in their list of affected vehicles and correct this oversight immediately. - I will not accept further delays, deflection, or excuses. GM must take full responsibility for this failure and respond immediately with a resolution.

While driving on a county highway during an extreme cold front, the vehicle experienced catastrophic engine failure due to low oil pressure. There was traffic that was impacted by this issue and the occupants (mother and child) were stranded in dangerous temps. This issue has been confirmed by a mechanic shop the vehicle was towed to. No warning from vehicle given, regular oil changes and vehicle maintenance performed. It is my understanding this is a known issue with this motor as far as oil consumption, faulty piston and piston ring assemblies and there have been class actions filed for these vehicles.

The contact owns a 2017 GMC Terrain. The contact stated while driving at an undisclosed speed, the vehicle stalled with no warning light illuminated. The vehicle was able to be restarted. The vehicle was taken to an independent mechanic, but was not diagnosed or repaired; however, the contact was informed that the engine oil levels were low, and oil was added to the engine by the mechanic. The contact stated while driving at an undisclosed speed the failure persisted. The contact stated that while the vehicle was parked, the contact stated that the oil level was low, and the engine was not consuming oil. The contact also noticed oil leaking from the bottom of the engine compartment. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 100,000.

Hole for timing chain guide bolt damaged by failed guide bolt

The contact owns a 2017 GMC Terrain. The contact stated while driving at an undisclosed speed, the contact discovered that there was an oil leak. No warning light was illuminated. The vehicle was taken back to the residence and the contact self-diagnosed the vehicle and was able to confirm that there was an oil leak, and the oil leak was coming from the rear main seal. A dealer was not contacted. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 115,000.

While driving home from work in single digit temperatures on Monday 01/20/25 the engine of my 2017 GMC Terrain stalled without warning at a traffic light. I was able to restart the vehicle and drive it the 1.5 miles home. When I exited the vehicle I noticed a trail of oil leading up the driveway into the garage. Oil continued to leak from the vehicle in the garage, and we had it towed the next day. Righter’s Auto Repair found the rear main seal had blown due to a frozen PCV system that GMC is well aware of and subject to TSB 5093c.The vehicle only has 64,856 miles.

My car lost oil while I was driving. I also lost power. I had my car over to a garage and the mechanic diagnosed it was a ruptured rear main seal caused by a frozen PCV system. GM knows about the problem but has not recalled it. It is very expensive to repair. And because the manufacturer knows about it but never told the consumer, is fraudulent.

My vehicle only has 78,000 miles on it and the timing chain needs to be replaced?! This is no longer under warranty because it’s been over 5 years but this should last a life time. Now I have a car that doesn’t start or run that I have to make payments on and no one wants to do the work on my car! I looked online and a bunch of people are having the same issue with the same exact car at similar mileage and the same issue! GMC needs to do a recall on this issue, many people are losing money and it’s a financial crisis.

We have had 4 transmissions since we bought the vehicle. It slows down to almost a stop after it hits 30 mph and makes weird noises all throughout the vehicle. The back right tire sticks to the pavement and jerks when i start to drive. The key ignition has been fixed several times and still sometimes won't turn with the key or come out. Yes Warranty told the repaid service company to fix whatever, and they did but it still after 2 more transmission hasn't fixed the issues. Engine light and not sure what else.

I was driving back home when I suddenly heard a loud pop and my car seat belt immediately tightened up. I saw smoke inside the car and the screen in my dashboard said "airbag service" There was no air bag physical deployed in the car so I believe it happened internally. Now my driver seatbelt will not retract and the front passenger seatbelt will not come out.

Vehicle repeatedly stalled while on highway, there were no warning lights on dash or anything indicating of an issue prior. Took vehicle to repair shop and after thorough investigation they reported that there was no oil in engine despite dashboard monitor registering oil life was fine. Oil changes are always completed regularly and on time for vehicle. Mechanic said that this is a known issue with GMC for this specific model where oil is consumed at an irregular rate. There is a lawsuit against gmc for oil consumption that includes years 2010-2014 where gmc was at fault however the lawsuit was filed before the 2017 model came out. It was later discovered that years ,2014-2017 also have this known defect however a recall has yet to be placed. Being a common symptom of this issue is frequent vehicle stall this really should be a recall. After speaking with a couple of other gmc dealerships they were aware it was a frequent issue as well but are uncooperative when it comes to the cost of repairs, an entirely new motor is needed to be replaced now for the vehicle being driven without oil. After several calls with a GMC representative I was advised to file a complaint with NHTSA to have you guys complete an investigation into the issie

Roughly every 8 months Sirius XM "radio" runs an automatically triggered free subscription period that includes "weather alerts". These alerts BLOCK part of the car's normal navigational (map) system, requiring UNNECESSARY MOVEMENTS to dismiss the prompts so one can see map details. These movements RISK DRIVING MISTAKES. The weather alerts are unhelpful and unwanted: trivial events that don't affect me. And they keep repeating the same alert multiple times per day. I once called Sirius tech support to have them shut that feature off, but they claimed they couldn't, and to just wait out the promotion period. Sirius XM comes with the car and I can't remove it. I suspect the prompts are a marketing gimmick to trick people into sampling their music channels when they fiddle in the Sirius menus trying to turn off the alerts. Others on social media have reported similar problems in different car models. (PS: I bought the car used in 2019.)

The 2.4-liter engine contains a defect that causes them to improperly burn off and consume abnormally high amounts of oil. The vehicle is available for inspection upon request. Excessive oil consumption cannot be reasonably anticipated or predicted and causes the engine to run while low on engine oil, putting me and other drivers at risk due to engine fire, unexpected engine failure, vehicle jerking, power loss, etc. Yes, both certified dealers, independent service centers, and myself have observed and noted the low levels of engine oil as soon as 500 miles after an oil change. I have spoken with GM representatives via phone about the issue, but they are not interested in inspecting the vehicle or offering driver support. They have consistently denied awareness of an issue despite hundreds of documented complaints and a pending class action lawsuit in the state of Missouri. There are no warnings, messages, or symptoms prior to discovering low engine oil levels. This issue requires drivers to self-monitor the issue every 500-1000 miles and requires an excessive number of oil changes to keep the vehicle at a safe level of engine oil for operation.

Car stalls out suddenly after stopping. The engine oil was changed as required and there were no warning lights on the dash. Took the car to a mechanic and the mechanic said there was no oil and metal shavings in the engine, and that the engine would need to be replaced for $10,000. The car is out of its warranty and slightly over 100,000 miles.

Oil goes back into motor blowing motor so causing you to get a new motor

2.4L Ecotec engines contain a defect that consumes excessive engine oil leading to: unanticipated engine shutdowns, engine stalls, engine knocking, unexpected loss of power, and vehicle jerking. The first instance I was still in a parking lot, the second on was on a local street traveling at 25 mph. During the third instance, My son and I have driven our car on 4 separate occasions and while driving on the freeway at 70 mph just after rush yesterday when the engine shut off. I took the car to my mechanic who informed me that my vehicle that has less than 88k miles is burning up the oil and soon will need the engine replaced.

4/3/2024 picked my car up from the mechanics at 5pm and when driving home going 35 mph the engine shut off. This incident is is tied to my previous incident.

My car was driving without issue until I stopped at a street light. My car started rocking front to back while sitting at the light and every other time I had to make a stop. The engine light came on. I had the vehicle towed to an auto shop where they confirmed that the timing chain broke. Due to this my engine was damaged to no repair. I would need to replace it. My gmc terrain is a 2017 with only 99,000 miles. I further learned that GM is aware of this issue but failed to recall this issue or warn owners that we were at risk. This can cause a vehicle to stop in the middle of driving which could cause a death if in the wrong place.

Rear main oil seal is faulty. It caused the vehicle to leak oil to the point where it was dry. This is a known issue with these vehicles and could have caused catastrophic damage to the engine. Additionally, this can cause the vehicle to stop running and/or catch fire.

While in park and driving, the passenger seat belt locks and will not unlock. You must unfasten belt and refasten it. It does this multiple times during a trip. This has occurred since 2020.

Broken rear main seal broke which causes oil leak. Almost all GM vehicles around my year have the same issue resulting in blow engine. $2000 to repair and GM told me they know of this being an issue but won’t do anything to resolve.

In September of 2022 my gmc automatically shut off right in the middle of traffic on a Friday night. No warring, no lights to indicate that something was wrong with my vehicle. I took it to a mechanic shop and they said nothing was wrong and they did a diagnostic test on the car and no codes popped up. A week later my engine light came on. And my car died again. Thankfully, I had an extended warranty on my car and took to another mechanic shop. It turns out the timing changes on my car needed to be replaced. Fast forward to today Jan 22,2024. I smelled burning oil every time I would drive the vehicle. The rear main seal and PCV was leaking in between my engine and transmission. I lost 5 quarts of oil between Wednesday and Sunday. My oil light never came in. Thankfully, my engine didn’t lock up. It is currently in the shop getting repaired. My car is still under an extended warranty.

The air bags will show that they are shut off while we are driving down the road with my wife sitting in the seat and they will also does it if we are just sitting in the drive way. Also they had a recall in the older models of this car for the pvc valve getting clogged and building pressure and causing the lower seal to bust and that happed to my car but they never gave a low oil light when it happed. All that happed was my wife was driving and the lower engine power came on while she was driving in traffic causing her to freak out and feel unsafe with my kids in the car as well. I contacted them about and they said there is no recall for the car at all about it. They clearly still had the same issues in my car because the pvc valve was clogged and then now I’m loosing all of the oil from my motor. When I went to out oil in it after work I had to add 4.5 quarts of oil to it and it only holds 5 quarts. It still never had a low oil light when I went to start it to get it to level ground so I could check it. Clearly this is a safety issue and I don’t want it to happen to someone while they are on the Interstate during heavy traffic and potentially cause an accident.

main seal blew is in dealership now. it was not running right as i drove it was afraid it would die in the middle of the road. just inspected at the dealership. i got the engine light about a mile from my home where it sat till it went to the dealership.was over 4 quarts low with oil but never had oil light or anything else before it showed engine light.

I was driving our 2017 GMC Terrain in subzero temperatures when my vehicle started making sounds and loosing power. With in seconds I heard a pop, and then my dash went crazy with alarms. I had it towed to my local mechanic who determined that the vehicle's engine was seized do to a frozen PCV valve that caused the engines real seal to give away. If need be, the the vehicle is currently available to be examined. My family's safety was in danger because of the location and frigid temperatures that were present at the time of the breakage. The vehicle has not been examine by a GMC dealer, just an independent mechanic. There was no warning what so ever of a possible problem. The vehicle started making sounds and loosing power. With in seconds, I heard a pop and all the lights on the dash light up. We had no other issues with this vehicle leading up to the breakage.

On Friday, January 19, 2024, I was driving home from school at night in my 2017 GMC Terrain when suddenly my car was chugging and quit. my steering and brakes froze. Other cars were passing me and it was snowing. I was scared someone was going to hit me. I was able to start it up again and to get it to a Walmart parking lot just down the road, but before, it would chug and quit again. My steering was hard. There was no warning light or service light on dashboard telling me something was wrong. I called my sister to come get me. The car would start, but would keep quitting. I called a tow truck and had it towed to the condo. The next day, I went out to start it and it would start and oil light came on. It smelled. I turned it off. I called another tow truck and had it towed to a Mechanic at a shop. He informed me on Monday that the engine was no good due to lack of oil. Even though he said there was 15% left on the gauge. He said these cars have had problems of using excessive oil and he has had to replace and fix them. He also said others had same issue and no warning light as well. I have to replace my engine. He said the cost would be between $5000-$6000. I can't afford that going to school. I'm afraid that if someone else has this problem they could get hurt. I am going to contact General Motors about this, but I'm sure they won't help. Any Suggestions?

In certain makes of General Motor vehicles there is a defect with the PCV system in which the system can freeze in cold temperatures which in turns causes excessive crankcase pressure in the engine, and can lead to a dangerous loss of motor power due to this defect. The dangers of this defect can be catastrophic to myself and others on the roadway as the loss of motor power can happen suddenly and can happen while the vehicle is being driven. General Motors has released many service bulletins regarding this specific defect. The most recent service bulletin that was issued was GM January 2019 Bulletin PIP5093C, so they are aware of this dangerous problem in these vehicles. For my vehicle I have had a certified GMC dealership diagnosis the problem, and submit their findings to General Motors. There were not any warning lamps, messages, lights, or symptoms signaling that there was a problem prior to the occurrence on January 15th, 2024.

Rear oil seal failed resulting in engine oil pressure loss and vehicle was stopped in middle of roadway

It's a known problem with gmc with a lawsuit for the PVC pipes clogging and blowing the main rear oil seal causing the vehicle to quit running

I just had an oil change in late December of 2023. As I was driving to work on [XXX]. My engine locked up. There were no warning lights. By the time I was able to pull over, a rod had gone thru the engine. Apparently there was an oil leak but no warning lights. This has not only caused me to have to purchase a new engine but could have resulted in a collision while driving. After doing some research this is a known defect by GM and a class action lawsuit. GM has failed to recall these vehicles for a known defect. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased this Vehicle in February of 2023, I had a problem shortly after with the oil always being low. I was adding oil to it all the time. 7 months later the engine blew. This is a very faulty problem with this engine that I am NOW finding out. This problem needs to be addressed and fixed. Now I am stuck with a vehicle that I still owe money on that will cost me 6 to 9 thousand to replace the engine.

The contact owns a 2017 GMC Terrain. The contact stated while driving approximately 65 MPH, the vehicle started losing motive power. The contact was able to pull to the side of the road, and the vehicle stalled. There was no warning light illuminated. The vehicle failed to restart after several attempts. The vehicle was towed to an independent mechanic, who diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle was repaired; however, the contact stated that the vehicle was experiencing an abnormal oil consumption after the engine replacement. The contact stated that there was no evidence of an oil leak. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.

The latch for the rear hatch/door does not release every time. There have been instances when itmes have been in the cargo area and when the button is pressed, it will not release the latch. This causes someone to have to crawl over the back seat to retrieve the items from the cargo area. This also is causing my son to have to store items, that would normally be in the crgo area, on his back seat. I owned a 2015 terrain and had this same issue. The latch was replaced but still did not operate correctly.

The contact owns a 2017 GMC Terrain. The contact stated that while her daughter was driving at an undisclosed speed, she observed white smoke coming from the vehicle, and the vehicle lost motive power. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who determined that the vehicle was consuming an excessive amount of engine oil. The vehicle was not repaired. The vehicle was taken to another independent mechanic, who confirmed the diagnosis. The vehicle was not repaired. The manufacturer was notified of the failure but did not assist. The failure mileage was 125,000.

I have to replace my rear drive shaft.

Engine shut off while doing 70 mph on interstate. There was no warning signs or nothing.

1. The car started making a noise then started surging and jerking. I'm not a mechanic, so I don't know what happened but it will not crank now. Yes, someone can come inspect the vehicle, by appointment only. 2. I was afraid that the car was going to blow up or the brakes would not hold. 3. No, the problem has not been reproduced or inspected. 4. No, the vehicle or component has not been inspected. 5. NO, there were no warning lights to let me know there was a problem.

2017 GMC Terrain motors consume oil at an excessive rate (1 quart per 1,000 miles). Getting an oil change every 5,000 miles, even consistently, puts the engine at risk for major internal failure and safety risks to the passengers. My engine in my 2017 GMC Terrain has a broken timing chain and internal damage due to the excessive oil consumption issue. The engine will have to be replaced. GM has known about this issue for years. GM is in several lawsuits for this issue, but GM has failed to recall the parts of the motor that are excessively consuming oil. They refuse to help cover repair costs even though the costs are due to their poorly designed motor.

The contact owns a 2017 GMC Terrain. The contact stated while driving at approximately 40 MPH, the check engine warning light illuminated, and the vehicle failed to remain idling. The vehicle was driven to the residence and parked. The vehicle was not able to be restarted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the issue. The failure mileage was 79,500.

We have had many GM vehicles my husband worked at GM retired now. Our complaint is we have a GMC Denali 2017 only 79000 miles on it. All upto date changes regularly all. Other like Transmission oil changed all upkeep to date. Transmission needs rebuilt. We are in our 80’s And don’t beat up our cars. Replace or rebuild transmission 3500 to 4500 bucks. That is a lot of money for us. No longer covered. It shudders when you drive at any speed and feels so unsafe. Took it to GM garage and they couldn’t find anything wrong. No warning lights came on and we paid over 150 to have it checked out so with the shuddering getting worse and not feeling safe to drive we took it to a Transmission shop and he took it out and said the Shuddering was caused by something in the transmission. I have seen on google where GM is having a lot of problems in this area. We just need help with the repairs. Thank you. A retired GM worker Lordstown, Ohio [XXX].

I was on the interstate, heading out of town. I heard a loud noise from under the car. The car started slowing down and would not accelerate. This could have been very dangerous if I had been in the middle of 5:00 traffic. I took the next exit in front of me and pulled into a gas station. Looked under car and seen no obvious damage. Got back in and the car and put it back into drive. It would barely pull and then quick pulling all together within a few feet. The D/drive light started flashing. No warnings at all before this happened. I was 200 miles away and had to have it towed back home. Put it in the GMC shop and was told it needed a transmission.

The engine burns oils twice as fast as it should and gives no warning of a problem. I am 3 years into payments on this vehicle and the engine is shot due to this issue. I have under 80,000 miles but this is a major problem that GMC is not addressing its very frustrating I will have to pay off a damage car they sold and now buy a new for an obvious problem they won’t acknowledge

Due to cold weather the PCV froze which caused pressure to build up in the vehicle’s crankcase which caused the rear main engine seal to pop out. Results in losing all engine oil without and warning driving down the highway. I was lucky enough to get off the highway but currently without a vehicle due to possible engine damage

Engine seizing at highway speeds cause oil to blow out the rear main seal…

In 10 degree weather after warming the car up and driving 15 miles began noticing exhaust smell but wasn't sure it was my car. No warning lights. Arrived at destination parking lot and car began to run rough and stall out and only then did engine light and oil pressure light come on. Strong exhaust/gas smell. Stranded in frigid weather with passenger in a wheelchair. Had car towed to dealer- pvc port plugged causing oil pressure to blow out rear main seal losing all oil causing damage to the engine and components. Warning lights did not come on until damage was done. Discovered it was a known issue with this engine and class action lawsuit has been filed. Was fortunate we were not on the road when this happened.

The contact owns a 2017 GMC Terrain. The contact stated while driving 5 MPH and merging into traffic, the vehicle stalled. The contact stated that the check engine warning light was illuminated. The vehicle was not drivable. The contact towed the vehicle to an independent mechanic and was informed that the timing chain had fractured, and the engine needed to be replaced. The vehicle was not repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 79,000.

Vehicle has 37,000 on it and the timing belt/chain is bad causing value problems.

They’re a class action law suit going on now, about the pcv orifice on my car. This is what happened with my car the pcv orifice clogged and frozen then causing my rear main seal to break and loose oil. No oil lights come on when the car is low on oil. Also even if you fix the pcv orifice it could still happen again.. which means it could leave me and my young daughter stranded on the side of a road hi way or interstate and I’m not comfortable with this and the car dealership needs to get a permanent fix so this doesn’t happen repeatedly… I don’t even feel comfortable driving the car anywhere I’m afraid I will be left on the side of the road.

Car died out of nowhere. Towed to dealership. Upon inspection we were told that the engine needs to be replaced. Had a 3rd party come to investigate and gave a diagnostic report. GM has notices and there are articles outlining the defect/failure of the engine due to excessive oil consumption and issues with PCV and rear main seal.

The contact owns a 2017 GMC Terrain. The contact stated that the vehicle was taken to the local dealer to be serviced under NHTSA Campaign Number: 22V137000 (Exterior Lighting). After the recall repair was performed, the contact discovered that while driving at night, the low-beam headlights illumination was extremely low, creating a visibility hazard for the driver. The vehicle was taken back to the dealer who indicated that no failure was found, and that the headlights operated as intended. The manufacturer was notified of the failure. The failure mileage was 54,000.

On Christmas Eve, I was driving home from the Northpark Mall in Joplin, MO during a record winter storm passing through my area. I was 2 miles from my house when the car went into what I can describe as a "fail-safe" mode and I was able to make it home safely. When the weather cleared up and I felt comfortable going outside again, I checked the oil and nothing was in there. It had leaked the rest of the way home. When I was doing a full inspection, I noticed the PVC Evac system valve was full of water from being frozen. When I called the dealership I originally bought my car from, he laughed and said he had the exact complaint come through for another GMC vehicle. I've looked online for options to fix it, but the solutions I found are costly and time-consuming. I live in an eight-person household and would like to be able to drive my own vehicle again. Thank you.

Was driving on a highway on cruise control When it automatically disengaged by itself When I stepped on the gas the car began to shake violently, And it was not shifting years correctly. I was able to pull over and realize that the transmission Was a problem so I was able to drive manually to local dealer who diagnosed the problem as needing a new transmission. The vehicle is 2017 and has less than 63000 miles.

The front passenger seat belt locks on passenger and will not release unless it is completely unbuckled. It keeps doing this for no reason. This was brought to dealer’s attention one to two years ago and they said I would have to pay cost of repair since warranty was off even though I purchased an extended warranty with this vehicle. The service department claims to have taken it apart and cleaned it but could not find problem. The problem is bad since passenger has to unbuckle belt multiple times during a trip.

The rear main seal is out, which is causing an oil leak. The intake manifold failed because the pvc system has a clog which has caused too much pressure to build up and caused the rear main seal to blow out. (PVC pipe is freezing over in cold temperatures which causes the failure of the main seal to blow out subsequently leading to additional major issues and parts failure. This issue has occurred in an overwhelming amount of vehicles.)

Pulling into work parking lot on Saturday 31Dec2022, my engine died, thinking it was the alternator or the starter, had it towed to a repair shop. Didn’t find out until Monday, 2Jan2023, that the engine completely locked up. The rear seal blew out and drained all the oil. I have been reading up on this and apparently this is reoccurring thing in said make and model of 2017. GMC and GM have to put out a recall on these vehicles with this manufacturing error/problem. Now I have to get a new goddamn vehicle because I cannot afford to get the engine replaced, which costs around $7000. End of message.

In very cold weather the 2.4 engines will blow the rear main seal out and cause rapid oil loss causing engine failure. This is the second time it has happened. First time was February 2022 and the dealer said they havent seen this problem before

It was Christmas weekend, the coldest days our area had seen this time of year in decades. Temperatures were around 0 degrees, with wind chills that were -25 below. The check engine light had come on the day before. My husband was literally driving to the mechanic to have it looked at, when the vehicle completely broke down across the street from his destination. Thank God he was approaching an intersection when it died, and not traveling at a higher rate of speed, where he could have been injured, or others on the roadway around him could have been injured. We had the vehicle towed to our GMC dealership where we purchased it just three years prior. Upon inspection from the mechanic, it was determined that the PCV valve was plugged causing pressure on the rear main seal, which then blew out, bending the valve covers, breaking the timing chain, the water pump chain, and damaging the head gasket. The whole bottom of the motor was covered in oil. Absolute catastrophic damage!! I’m told the cost to replace these parts to essentially rebuild the engine, would start at approximately $4000. A brand new engine would be about $11,000! This entire situation to me is just unbelievable! A five year old GM vehicle, with just 46,000 miles on it! This should not have happened. In researching, I’ve been made aware that this is a common issue with GMC Terrains. In fact there was Technical Service Bulletin made by GM for 2010-2013 models whose PCV valve would clog causing rear main seal blow outs. The holes were so small in diameter, technicians would use a 1/16 drill head to clean it out. This is an obvious manufacturer defect that apparently hasn’t been resolved in the newer model Terrains. How has this not been a safety recall yet?? Shame on you GM! This will be the last GMC vehicle I will own!

timing chain issues resulting in a loss of power of the vehicle while driving. The vehicle stalls out and shuts off. Or it will go into power saving mode and slow down to only 20mph. It did this to me one a MAJOR HIGHWAY and I almost was in an accident. Way to many issues with gmc owners and the timing chain on their vehicles

On5/3/2022 we were driving on I65 around Shepherdsville KY. It was pouring down rain and our windshield wipers stopped working and stuck in the up position. We had a semi on each side of us. This made it even more difficult to see due to the rain coming off of their tires and spraying onto our window. We had to slow down to a dangerous low speed on the interstate due to the difficulty seeing. We made it to the shoulder after almost being hit by a semi We had to sit there until the rain stopped. This was extremely dangerous in itself being that it was on an interstate with high speed limits. We had no choice but to stop in the town of Shephardsville and get a hotel room. We are still trying to make our way back home at this time to IN. This has not been expected by anyone at this time. There were no warnings of any kind.

transmission jerking at low speeds no power,was told by dealer i need a new transmission i only have 60,000 miles on my 2017 terain gmc no warning indicator lights came on

The contact's wife owns a 2017 GMC Terrain. The contact stated while his wife was driving 40 MPH, the vehicle started to stall, and shuddered inadvertently. The check engine warning light was illuminated. The contact met his wife at the scene and noticed that oil was leaking from underneath the front end of the vehicle onto the ground. The contact refilled the engine oil and his wife was able to drive the vehicle to their residence; however, oil continued to leak while she was driving. The contact refilled the engine oil and the vehicle was taken to the dealer, where it was diagnosed that the rear main seal was fractured and had failed. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that there were no recalls associated with the failure; however, the manufacturer offered to cover 13-percent of the repair cost. The failure mileage was approximately 94,000.

Driving home from work and was about 4 miles away from home when the "service stabilitrak' and "reduced engine power" lights came on. Safely drove home, parked vehicle on road to shovel driveway (snow storm). When I went to start it to move it into driveway "oil pressure" light came on. After moving it off street noticed oil on road where vehicle was sitting. Had towed to dealer where I get my oil changed (which was done about 3 weeks prior) they stated rear main seal went causing oil to drain from engine which also ruined my valves and threw out the timing. GM says they'll pay 25% of total $6200 bill. Although GM has yet to return a call regarding the case I opened with them on this asking for a larger percentage.

The rear main seal broke. Causing oil to leave the reservoir and empty the engine. This was due to a frozen pvc from cold temperatures. My vehicles engine light came on and I pulled over immediately noticing there was no oil. but there was never an indication of low oil. My vehicle is serviced with every 5k miles for oil. 109,000 miles on a 2017 terrain. Blew the rear main seal and caused other damage as well. This is a manufacturers faulty equipment.

Available for inspection upon request. The rear main seal is out, which is causing an oil leak. The intake manifold failed because the pcv system has a clog which has caused too much pressure to build up and caused the rear main seal to blow out. There were no dash lights. My car was completely out of oil from the issue and I had no indicators. This issue has been check and confirmed by a GMC mechanic.

The Rear Main Seal broke, thus causing major oil leak. I have been doing my investigations and there are many out there like myself. This is NOT an easy fix and is very expensive! I suggest if anyone else has the same issue please report it.

While driving on the highway with my child, vehicle suddenly went into reduced power mode. 5 minutes later after exiting the highway, the low oil pressure Alert came on. The vehicle was parked two minutes later then towed home. After towing it to my local certified dealership, it was determined the pcv was clogged with ice resulting in a blown rear main seal. There was a recall for a defect in earlier terrains for this same issue (See SB 14882). Currently GM will not cover repair costs under this specific recall despite this vehicle apparently having the same 2.4L Ecotek engine. Apparently this a known cold weather issue for this vehicle.

The contact owns a 2017 GMC Terrain. The contact stated while driving 30 MPH, the "Low Oil Pressure - Shut Engine Off" message was displayed. The contact was able to pull into his driveway and parked the vehicle. The vehicle was taken to an independent mechanic who diagnosed that the rear main seal had failed, and the failure was related to GM Technical Service Bulletin: 14882. The dealer and the manufacturer were notified of the failure and informed the contact that they could not assist because the VIN was not included in the Technical Service Bulletin. The manufacturer referred the contact to the NHTSA for assistance. The vehicle was not repaired. The failure mileage was approximately 66,000.

The contact owns a 2017 GMC Terrain. The contact stated that after his wife had parked the vehicle, the oil light appeared on the instrument panel. Upon exiting the vehicle, she discovered that oil had leaked onto the ground from underneath the vehicle. The contact was called to the scene and placed oil into the vehicle; however, the oil leaked out after restarting the vehicle. The contact then called a friend who was a mechanic and he discovered that the PCV valve had frozen which caused the rear main seal to fracture. The contact also discovered that oil spilled all over the bottom of the engine. The dealer was notified of the failure and informed him that there were no recalls. The manufacturer was also notified of the failure and referred him to NHTSA. The vehicle had yet to be repaired. The failure mileage was approximately 80,000.

Driver side head curtain airbags failed to properly deploy during rollover accident Not my vehicle, this is vehicle accident I responded to, Captain Fire Dept

Engine started consuming oil at around 90,000 miles. First noticed after a Oil change with the dealer we bought it from. Questioned them about it once we checked the oil, and noticed it being low after experiencing a engine noise. Dealer had us bring it back , refilled it, and test drove it for 20 miles. They sent it back with us, stating it may not have been topped off correctly. Noticed the issue several more times, and told the dealer , they then had us to a oil consumption test. After test was concluded recommended that the piston rings be replaced at a cost of $2202.02. GM first refused coverage even though this is a known issue with Terrains with the 2.4 cyl. engine. Dealer resubmitted to GM rep. , Rep. admitted this is a known issue, and that GM is waiting to see if they experience enough complaints to meet the 10% of production number before it is covered 100%. Contacted GM customer complaint line with no luck in getting additional coverage, even though GM extended coverage for earlier models with this issue.

The contact owns a 2017 GMC Terrain. The contact stated while driving approximately 25 mph, the vehicle lost electrical and motive power. The contact was able to restart the vehicle.

OnStar - I've had OnStar for several years and paid the bill annually by check. The company never sent a renewal bill this year. I contacted them via phone on 1-23-2021, 2-8-2021, 2-22-2021 and 3-9-2021. I used phone numbers 1-866-891-1233, 1-866-579-0028, and the OnStar button to talk to representatives. I also wrote letters to OnStar dated March 9 and March 27, 2021 without results. I had a confirmation # CN4175174. I never received a bill and now the safety device is cut off in my car.

PURCHASED GMC 2017 TERRAIN 1 MONTH AGO TODAY. THE FIRST WEEK I HAD IT THE ENGINE KEPT STALLING WHILE IDLING. I TOOK IT TO THE DEALERSHIP FOR THEM TO FIX. I GOT IT BACK AND IT SEEMED TO RUN HARD. 3 DAYS LATER I FOUND THAT NOT ONE BUT BOTH KEY FOBS WOULD NOT WORK. THE BATTERY IS BRAND NEW. WHEN I SPOKE TO SERVICE MAN AT DEALERSHIP, HE STATED THAT ONE FOB WAS FAULTY AND THEY WOULD ORDER A NEW ONE. I HAVEN'T HEARD BACK FROM THEM...TODAY I GOT INTO A FRONT END COLLISION WHERE THE AIR BAGS DID NOT DEPLOY CAUSING ME INJURY. ONLY AFTER THE FACT DID THE ALARM SOUND AND DASH MESSAGE CAME ON STATING SERVICE AIRBAG. THE FOUR WAY LIGHTS WOULD NOT STAY ON AND THE INTERIOR LIGHTS WOULD NOT TURN OFF. AND THERE WAS A SMELL OF SOMETHING BURNING.. NO RETURN CALL FROM GMC.

THIS WAS AN EXTREMELY TERRIFYING MOMENT, AS I WAS GOING 45MPH (PER THE SPEED LIMIT). AS I HAD READ EARLIER, THE 2018 TERRAINS ALSO SEEM TO HAVE THE SAME PROBLEM.

TL* THE CONTACT OWNS A 2017 GMC TERRAIN. THE CONTACT STATED THE DRIVER'S SIDE INSIDE DOOR HANDLE WAS FRACTURED. THE CONTACT WAS CONCERNED ABOUT CUTTING HER HAND ON THE DOOR HANDLE. THE CONTACT CALLED PENSKE CADILLAC OF SOUTH BAY (18600 HAWTHORNE BLVD, TORRANCE, CA 90504, (310) 697-1800) HOWEVER, THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS CONTACTED HOWEVER, NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS 39,000.

TL* THE CONTACT OWNS A 2017 GMC TERRAIN. THE CONTACT STATED WHILE COMING TO A COMPLETE STOP THE VEHICLE WAS UNEXPECTEDLY REAR ENDED WHICH FORCED THE VEHICLE TO SLIDE FORWARD UNTO THE HIGHWAY, THE IMPACT CAUSED THE AIR BAGS TO NOT PROPERLY DEPLOY WITH THE SERVICE AIRBAGS LIGHT ILLUMINATING. THE CONTACT SUSTAINED BACK INJURIES THAT REQUIRED MEDICAL ATTENTION, A POLICE REPORT WAS TAKEN. THE VEHICLE WAS TAKEN TO AN INDEPENDENT SHOP WHERE THE VEHICLE DAMAGE WAS BEING REPAIRED. THE DEALER WAS NOTIFIED OF THE FAILURE, HOWEVER ADVISED THE CONTACT TO CALL THE MANUFACTURER. THE CAUSE OF THE FAILURE WAS NOT DIAGNOSED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 53,000. THE VIN WAS NOT AVAILABLE.

I WAS MAKING A LEFT TURN DURING A GREEN LIGHT MY CAR WAS IN MOTION. A WHITE VAN WAS SPEEDING TOWARDS ME FROM THE DRIVERS SIDE GOING STRAIGHT AT ME AT HIGH SPEED WITH A RED LIGHT. THEY HIT THE FRONT DRIVERS END OF MY CAR WHICH MADE MY CAR SPIN OUT. THE AIRBAGS DID NOT DEPLOY. THE WHOLE FRONT END OF MY CAR WAS RUINED.

AT AROUND 20 MILES PER HOUR, WHILE ACCELERATING, ALL TORQUE IS LOST AND THE VEHICLE ENGINE REVS HIGH. IT TAKES A FEW SECONDS, THEN THE TRANSMISSION FINALLY SHIFTS INTO THE NEXT GEAR. THIS CAUSES A BIG JOLT. IT IS DANGEROUS, ALL POWER IS LOST, THEN SUDDENLY TOO MUCH POWER IS APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE. I HAVE TAKEN IT TO THE DEALERSHIP. THEY WON'T DO ANYTHING ABOUT IT. THE VEHICLE NOW HAS 40,502 MILES.

I HAD MY 2017 GMC TERRAIN DENALI FOR TWO YEARS AND HAVE ALREADY EXPERIENCED TWO SERIOUS ISSUES. ISSUE #1-I NOTICED A BURNING SMELL, GRINDING NOISE, AND HESITATION WHEN DRIVING. I BROUGHT IT TO THE DEALERSHIP WHERE I BOUGHT IT AND WAS TOLD THAT THERE WAS A FACTORY DEFECT WHICH CAUSED SOMETHING INSIDE MY TRANSFER TO BORE A HOLE THROUGH IT. DEALER COULD NOT GET THE PART FOR 2 WEEKS. IT WAS COVERED UNDER MY WARRANTY. A MONTH LATER WHILE GETTING AN OIL CHANGE AT A DIFFERENT AUTO SHOP, I WAS ASKED IF I RECENTLY HAD WORK DONE ONLY TRANSMISSION BECAUSE THE ENTIRE THING WAS LOOSE AND MOVING, AND THE CAR DID NOT DRIVE RIGHT. I WAS TOLD IT WAS NOT SAFE TO DRIVE. I BROUGHT IT BACK TO THE DEALERSHIP AND WAS TOLD THAT THEY COULDN'T FIND ANYTHING. THEY TIGHTENED THE BOLTS ON THE TRANSFER CASE AND CHARGED ME A $60 DIAGNOSTIC FEE (FOR THEIR ERROR). ISSUE #2-AT 63,000 MILES MY WIPERS STOPPED WORKING WHILE I WAS DRIVING AT ABOUT 30MPH ON A BUSY STREET IN THE POURING RAIN (VERY SCARY). I BROUGHT IT TO THE DEALERSHIP AND WAS TOLD I NEEDED A NEW WIPER TRANSMISSION AND WOULD COST $318 BECAUSE MY CAR WAS NOT PART OF THE RECALL. I EXPRESSED CONCERN THAT MY 2YO. CAR HAS NOW HAD TWO SERIOUS SAFETY ISSUES AND WAS TOLD 'CARS HAVE SO MANY MOVING PARTS AND PIECES THAT IT'S A WONDER MORE THINGS WEREN'T WRONG WITH IT'. I DO NOT FEEL SAFE DRIVING THIS CAR AND THE SERVICE MANAGER WAS CONDESCENDING AND COULDN'T CARE LESS. GMC NEEDS TO DO SOMETHING BEFORE SOMEBODY GETS SERIOUSLY HURT OR WORSE.

WHEN I STARTED MY VEHICLE THE RADIO DID NOT POWER ON. THE REVERSE CAMERA IS NOT WORKING NOR THE BLUETOOTH OR ANY OTHER FUNCTION WITH THE RADIO.

I WAS DRIVING DOWN THE ROAD AT 55 MPH WHEN A DEER RAN OUT AND HIT THE PASSENGER SIDE OF MY VEHICLE. IT BOUNCED AND ROLLED OFF THE DRIVERS SIDE. I PULLED THE VEHICLE OFF TO THE SIDE OF THE ROAD. ALL OF THE ELECTRIC COMPONENTS IN THE VEHICLE WERE ON. THE INTERIOR LIGHTS WERE ON, THE HAZARD LIGHTS WERE FLASHING AND THE CONSOLE WAS LOCKED UP. I PUSHED THE BUTTONS, BUT NOTHING HAPPENED. THE AIRBAGS DID NOT DEPLOY THERE WAS A MESSAGE ON THE SCREEN THAT SAY SERVICE AIRBAG (BUT THEY HADN'T DEPLOYED). I COULD SMELL SOMETHING BURNING, THE VEHICLE WAS SMOKING AND I COULD HEAR SOMETHING POPPING, I GOT OUT TO ASSESS THE DAMAGE AND MY VEHICLE WAS ON FIRE. THE VEHICLE ENDED UP BEING A TOTAL LOSS.. THIS IS HAPPENED IN GA AND THE STATE PATROL DID THE POLICE REPORT.

WHILE CHECKING THE REAR VIEW MIRROR A 1998 CHEVY TRUCK CAME TP A SUDDEN STOP ON THE HIGHWAY, AND I COULD NOT MISS THE TRUCK THE DRIVER CLAIMED HE THOUGHT HE HAD MISSED HIS TURN, WHEN MY SUV COLLIDED WITH THE TRUCK. THE POWDER CAME OUT BUT THE AIRBAGS NEVER DID COME OUT,AND THE PASSENGER SEATBELT LOCKED.

GMC TERRAIN. CONSUMER WRITES IN REGARDS TO ISSUES WITH THE RADIO. *LD THE CONSUMER STATED THE DASH DISPLAY NO LONGER OPERATES. THE SCREEN DISPLAY IS BLACK. DUE TO THE FAILURE THE BACKUP CAMERA, HANDS FREE PHONE, ON STAR, AND THE RADIO ARE INOPERABLE. *JS

THE VEHICLE'S CLIMATE CONTROL SYSTEM DOES NOT FUNCTION PROPERLY. THE AIR IS NOT PROPERLY DISTRIBUTED OUT OF THE AVAILABLE VENTS. AT TIMES, AIR IS ONLY DISTRIBUTED THROUGH THE FLOORBOARD VENTS. OTHER TIMES IT WILL ONLY BE DISTRIBUTED VIA THE DEFROSTER VENTS. RECENTLY, THE CAR WINDOWS BECAME COMPLETELY FOGGED UP WHILE DRIVING ON THE INTERSTATE AT NIGHT. I ATTEMPTED TO USE THE DEFROSTER, BUT ALL AIR WAS DISTRIBUTED TO THE FLOORBOARD, WHICH HAD NO IMPACT ON THE WINDSHIELD. I HAD ZERO VISIBILITY AND HAD TO PULL OFF ON THE SIDE OF THE ROAD. UP UNTIL THIS INCIDENT, THE PROBLEM HAD BEEN RESTRICTED TO A LACK OF COMFORT, BUT IT HAS NOW BECOME A SAFETY RISK. GMC HAS BEEN PREVIOUSLY MADE AWARE OF THE PROBLEM AND I WAS INFORMED GMC ENGINEERS WERE AWARE OF THE PROBLEM BUT DID NOT HAVE A WAY TO FIX IT.

TRAVELING ON STATE HIGHWAY 136 BETWEEN 50 AND 55MPH. THE LISTED VEHICLE STRUCK A DEER CAUSING SIGNIFICANT FRONT END DAMAGE. IMMEDIATELY FOLLOWING THERE WAS A VERY STRONG ODOR SIMILAR TO GUN POWDER. THE AIRBAG LIGHT ILLUMINATED AND ON STAR CAME ON LINE IN THE CAR DUE TO CRASH SENSOR NOTIFICATION. HOWEVER, THERE WAS NO AIRBAG DEPLOYMENT.THE ENTIRE FRONT END OF THE CAR SUSTAINED DAMAGE AS WELL AS THE RADIATOR. THE DRIVERS SIDE FRONT QUARTER PANEL ALSO BUCKLED. IT IS UNKNOWN AT THIS TIME OF FURTHER DAMAGE. THE VEHICLE SUSTAINED ENOUGH DAMAGE TO WHERE IT REQUIRED IT TO BE TOWED TO A DEALERSHIP BODY SHOP FOR FURTHER EVALUATION. BASED ON THE FRONT END AND QUARTER PANEL DAMAGE, THERE SHOULD HAVE BEEN AN AIRBAG DEPLOYMENT. THE LISTED VEHICLE IS THE ONLY VEHICLE INVOLVED WITH THE COLLISION. THE GEORGIA STATE PATROL INVESTIGATED AND COMPLETED A CRASH REPORT.

I WAS DRIVING 9PM ON A CITY ST RD, COMING UP ON A MILE LIGHT THAT WAS RED. THE ROADS WERE DRY ON A 5 LANE RD. THERE WAS 1 CAR AHEAD OF MY CAR WITH THEIR BRAKE LIGHTS ON . ALTHOUGH NOT NOTED ON POLICE REPORT THE CAR WAS STOPPED APPROX 5 TO 7 CAR LENGTHS PRIOR TO THE RED LIGHT. I HAD BEGAN TO SLOW DOWN BUT DID NOT REALIZE THE DRIVER AHEAD WAS NOT SLOWING DOWN BUT STOPPED. I SWERVED TO THE RIGHT AND AS NOTED IN PICS BELOW THE DRIVERS SIDE OF CAR HIT THE OTHER DRIVERS PASSENGER BACK CORNER. I ENDED UP IN A PARKING LOT ON THAT CORNER. OTHER THEN THE MEDICAL TERM COOP TO COOP THAT ALSO AIDED IN MY HEAD INJURY, I ALSO HIT MY HEAD 2 TIMES AT MY HAIRLINE ON THE STEERING WHEEL AND THEN MY LEFT CHEEK. I WAS DIAGNOSED AND SUSTAINED A SEVERE CONCUSSION/ BRAIN TRAUMA. I WENT TO THE EMERGENCY ROOM TWICE FOR CARE OF WORSENING SYMPTOMS AND WAS INCAPACITATED AND OUT OF WORK FOR ABOUT 6 WKS. WHICH WAS STILL TO FAST TO RETURN, BUT I COULD NOT AFFORD BEING ON DISABILITY. FOLLOWING THE ACCIDENT THE CAR WAS TAKEN TO THE CITY TOW YARD, AND WAS ASSESSED WITHIN A WEEK BY THE INS ADJUSTER AS TOTAL LOSS. FROM THERE IT WAS TAKEN TO A JUNK SALVAGE BUSINESS. DUE TO MY INCAPACITATION I HAD NO MEANS TO LOOK INTO CONCERNS RELATED TO WHY THE AIRBAGS DID NOT DEPLOY. I AM A NURSE PRACTITIONER THAT NOW HAS SHORT TERM MEMORY LOSS, MIGRAINES, AND ATTENTION DEFICIT DUE TO THE BRAIN INJURY. I HAVE NO WAY OF FINDING OUT IF THE AIRBAG SENSORS WERE DEFECTIVE OR NOT BECAUSE, ALTHOUGH I'M ATTEMPTING TO TRACK THE CAR IT'S BEEN DIFFICULT, AND UNSURE OF MY RIGHTS TO THE CAR IF I CAN TRACK IT DOWN. THE BIGGER SURPRISE WAS THAT I RECEIVED A RECALL NOTICE ON MY 2018 GMC TERRAIN JUST TODAY, BUT HAVE NO ANSWERS ON THE 2017. PLEASE HELP IN ANYWAY WITH WHAT I SHOULD DO. SINCERELY *TR *JS

HEADLIGHTS, HIGH AND LOW BEANS ARE ALMOST USELESS, THEY ARE NOT BRIGHT ENOUGH, BARELY CAN SEE TO DRIVE IT AT NIGHT, ESPECIALLY IF RAINING, TOTALLY ALMOST LIKE BEING BLIND.

VEHICLE WAS PARKED WITH THE MOTOR RUNNING. REACHED OVER FROM THE PASSENGER SEAT AND TURNED THE MOTOR OFF. VEHICLE BEGAN TO ROLL BACKWARDS. WAS ABLE TO TURN VEHICLE BUT UNFORTUNATELY BACKED INTO THE DOOR OF A PARKED TRUCK TURNING THE IGNITION OFF SHOULDN'T START THE VEHICLE TO MOVE.

TL* THE CONTACT OWNS A 2017 GMC TERRAIN. WHILE DRIVING 32 MPH, THE CONTACT'S VEHICLE STRUCK A PARKED VEHICLE. THE AIR BAGS DID NOT DEPLOY. A POLICE REPORT WAS FILED. THE CONTACT SUSTAINED INJURIES TO THE HEAD AND MOUTH, AND SUSTAINED A MILD CONCUSSION. MEDICAL ATTENTION WAS REQUIRED. IT WAS NOT DETERMINED WHETHER OR NOT THE VEHICLE WAS DESTROYED. THE DEALER AND MANUFACTURER WERE NOT MADE AWARE OF THE CRASH. THE FAILURE MILEAGE WAS APPROXIMATELY 2,850.

I WAS DRIVING AND INSIDE ALARM CAME ON SOUNDED LIKE A FIRE ALARM. HOWEVER NO LIGHTS IN THE CAR CAME ON INDICATION SOMETHING WAS WRONG, TIRE PRESSURE WAS GOOD, EVERYTHING AS FAR AS MY EYES COULD SEE IT WAS FINE EXCEPT THAT AN ALARM KEPT GOING OFF COMING THRU THE SPEAKERS. I PULLED OVER GOT OUT LOOKED AROUND THE VEHICLE. NOTHING! MADE SURE ALL DOORS WHERE LOCKED AND EVERYTHING GOOD ALARM STILL GOING OFF. NOT THE CAR THEFT ALARM AN INTERNAL ALARM THRU THE SPEAKERS OF THE CAR. PLEASE HELP AS I AM SCARED TO DRIVE MY VEHICLE BECAUSE MAYBE IT WAS TRYING TO TELL ME SOMETHING IS WRONG. IT EVENTUALLY WENT OFF AND I PULLED OFF VEHICLE DROVE FINE.

I'VE HAD MY TERRAIN FOR 3 MONTHS. CAR HAD 3400 MILES AT THE TIME OF THE ISSUE. BACKED OUT OF MY DRIVEWAY, PUT THE CAR IN DRIVE AND IT WOULDN'T GO. THE CAR WOULD REV UP BUT WOULDN'T MOVE FORWARD. HAD TO PUT THE CAR IN NEUTRAL AND PUSH OUT OF THE MIDDLE OF THE STREET. CAR WAS STRANDED IN THE STREET FOR THREE DAYS DUE TO THE DEALERSHIP SERVICE DEPARTMENT BEING CLOSED. EACH DAY I TRIED TO PUT THE CAR IN DRIVE AND IT STILL WOULDN'T GO WHEN PUT IN DRIVE OR MANUAL ONLY REVERSE. CAR WAS TOWED TO THE DEALERSHIP AND SAT FOR ANOTHER DAY BEFORE THE DEALERSHIP COULD GET TO IT. DEALERSHIP CALLED AND THE CAR WOULD DRIVE WITH NO ISSUE. ASKED IF SOMETHING COULD HAVE SHIFTED WHEN THE CAR WAS TOWED SO THEY KEPT THE CAR ONE MORE DAY TO RUN SOME DIAGNOSTIC TESTS WHICH STILL RESULTED IN NOTHING BEING FOUND.

BLIND SIDE ALERT ACTIVATES WHEN IT IS RAINING AND THERE ARE NO CARS NEARBY. THIS ONLY OCCURS WHEN RAINING. NO CODES ARE THROWN SO DEALER SERVICE WON'T TROUBLESHOOT. THIS CAN ONLY BE REPRODUCED ON A HIGHWAY OR PARKWAY, WHEN IT IS RAINING AND NO OTHER CARS ARE NEARBY. CANNOT BE REPRODUCED ON REGULAR STREETS WITH OTHER CARS AROUND. I'VE HAD MY CAR IN TO THE DEALER SERVICE 3 TIMES, ALL WITH THE SAME RESULTS. NO CODES IN THE COMPUTER AND CANNOT REPRODUCE. THE SERVICE DEPARTMENT ONLY TESTS ON THE LOCAL STREETS. THERE ARE OTHER CARS AROUND, SO HOW CAN THIS BE AN ACCURATE TEST???

SIDE BLIND SPOT ALERT COMES ON AND OFF WHEN RAINING OR SNOWING WITH NOTHING THERE, THEY SHOULD TELL YOU THIS WILL HAPPEN BEFORE YOU PAY EXTRA FOR THIS PACKAGE, HOW DO YOU KNOW IF IT WORKS OR NOT WHEN DRIVING DOWN HIGHWAY

OUR NEW TERRAIN HAS "VEHICLE IN FRONT" VISUAL WARNING SYSTEMS. WE WERE FOLLOWING A TANKER TYPE SEMI ON THE INTERSTATE AND PULLED ALL THE WAY UP BEHIND THE TANKER SEMI (WITHIN 25 FT) AND THE VEHICLE IN FRONT LIGHT NEVER CAME ON. WE TESTED THIS ON ALL TYPES OF CARS AND TRUCKS AS WELL AS STANDARD BOX TYPE SEMI AND IT WORKED PERFECTLY. I HAVE PICTURES OF THE REAR END OF THE TANKER SEMI IN WHICH IT DID NOT DETECT AT ALL.
