Auto wash truck quit, dead would not restart, tow service disconnected battery and reset. Okay after. Visit to dealer service they said nothing wrong. Driving yesterday in the rain quit 4 times on the road driving, it would restart each time. Warning on the dash would flash at times "Hands on the wheel" while driving ? This is a serious safety issue. Intermittent when it gets wet, new truck, 1,800 miles, no alterations. Dealer service no help, it has hard codes, CAN Bus communication issue, water intrusion likely cause, we are afraid to operate on the road, help please.

I started the vehicle in the morning, and noticed a knocking noise from deep inside the engine. Took the vehicle to the dealership, the knocking be turned into squealing and grinding and banging, check engine light came on, and vehicle died in front of the service department door. I’m an experienced auto technician and know that that was a connecting rod bearing knock. And now need a new engine on a vehicle with 919 miles on it.

2026 Chevrolet Silverado 1500 Crew Cab RST with the RST select package. The "Chrome-Like" trim inside and outside reflective the sunlight badly and depending on travel direction and Sun position, horrible reflection appears and momentary blinds you. It is very comparable to having the sunlight reflect off a mirror and into the driver's face. There are two different areas of "chrome-like" trim in the middle of the dash that shine directly into your face, occasionally it will shine and reflect into the driver's side rear view mirror and place and line across the mirror, which impedes the viewing through the mirror. The reflection also occurs off the Chevrolet symbol off the middle of the steering wheel, this one is not as bad as the others, but still annoying. The reflection various and the pictures don't show how intense and bad it really is. The Chrome "Turbomax" emblem was removed from the hood because that would reflect and shine back into the truck. Is there anyway to pass new rules to stop having highly reflective materials on the interior and exteriors of vehicles.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that the message "Service Brake Assist" was illuminated intermittently. The vehicle was taken to the dealer, where the message was reset on several occasions. Additionally, the dealer determined that the failure was possibly due to a low voltage issue, and the vehicle was operating as designed. The contact stated that the failure had recurred. The dealer was contacted and informed the contact that a towing agent would towed the vehicle to their location. The vehicle was not diagnosed or repaired. The manufacturer was not yet contacted. The failure mileage was 85.

Turn signals do not provide any audio signal letting you know they are on and working. GM is unable to correct issue.

THE FIN ANTENNA ON TOP OF THE TRUCK HAS COME LOOSE, I GOT A CONTINOUS MESSAGE FOR THE LAST 2= MONTHS. SERVICE EMERGANCY CALLING MY TRUCK IS 6 MONTHS OLD NOW, BUT THIS HAPPENED 2 MONTHS AGO. I TOOK IT TO THE DEALERSHIP, FRIENDLY CHEVORLET WHERE I BOUGHT IT. TECH GUY SAYS I MUST HAVE HIT SOMETHING. I CALLED GMC AND ASKED ABOUT PRODUCT DEFECT, WAS TOLD THATS NOT THE CASE.I ORDERED A NEW ANTENNA 4-12 26 GMC HAS NONE IN STOCK WHICH LEADS ME TO BELIE VE THIS IS AN ONGOING PROBLEM. GMC SAYS THIS IS NOT COVERED BY WARRANTY. THIS IS GOING TO BE A 600= DOLLAR EXSPENCE FOR ME. THIS ANTENNA IS FOR ONSTAR AND MY PHONE CONNECTION

OnStar Super Cruise, while using super cruise the vehicle tried to change lanes with another vehicle in the other lane. I had to fiscally override the super cruise to prevent an accident. This happened on three separate occasions.

Purchased truck in May of 2026 from Chevy dealer. Truck had around 1500 miles on it. Within 1 week the truck was shifting, very roughly, for no apparent reason making it lurch. I brought it to a local Chevy dealer, who ran it, showing a fault. I got the truck back from the dealer, who said tech had looked at it, and cleared the "fault" that was showing up. less than 1 week after that, the truck started doing the same thing, and I am bringing it back to the local Chevy dealer this week. The dealer I purchased the truck from said it was a trade in because the owner didn't like the truck. I'm concerned the dealer I bought the truck from may have known about the problem when I purchased the truck, and this may be the 3rd time that the truck has been back to a Chevy dealer for this problem. I looked on line and found Chevy has has hundreds of thousands of recalls on this 6.2 liter L87 engine, and there is a class action suit involving this engine from previous years, as well as hundreds of complaints regarding the 2026 version of this engine.

I am writing regarding an ongoing and serious issue with my 2026 Chevrolet Silverado 1500 RST 2.7L that continues to occur despite multiple visits to the dealership. Recently, as I was leaving my house, I entered my truck and started the vehicle as normal. Immediately after startup, approximately eight warning lights and system failure messages appeared on the dashboard simultaneously. The warnings included the Check Engine Light, ABS warning, Brake System Failure, Service Steering Column Lock, Service Traction Control, Service ESC, Service Brake Pad Monitor, and Trailer Brake Disabled warnings. At that point, the truck became undriveable. Although I was able to shift gears, the vehicle would not move properly in either Drive or Reverse. Due to the severity of the issue, I turned the truck off and left it parked overnight. The following day, all warning lights and messages had disappeared completely. This situation is extremely concerning because the vehicle appears to fail randomly without warning. I no longer feel safe driving the truck, especially with my children in the vehicle, because I fear it could stop functioning again at any time and potentially create a dangerous situation. I have already taken the truck to the dealership multiple times regarding this issue. However, I have repeatedly been told that they cannot properly diagnose or repair the problem unless the warning lights are actively present at the time of inspection. Since the issue is intermittent, this has made it very difficult to get the truck repaired, even though the problem clearly continues to occur. I am requesting that this matter be taken seriously and investigated further, and because this is a new truck that barely has 7,833 miles on it.as this appears to involve critical safety systems including braking, traction control, steering, and vehicle drivability. I depend on this truck daily and need a permanent resolution to this problem as soon as possible.

2026 Chevrolet Silverado 1500 Safety Issue Summary: I am filing a complaint regarding critical safety defects with my vehicle. The truck displayed warning messages for traction control service and brake system failure on the instrument panel while parked in my driveway, prior to the vehicle becoming inoperable, I experienced dangerous driving conditions including swerving similar to hydroplaning on two separate occasions. Details: The vehicle was picked up on a flatbed on May 11th, 2026 because it would not start or run. When I drove it before this incident, I experienced the vehicle swerving dangerously similar to hydroplaning on two different occasions 5/1/26 and 5/9/26. Upon inspection, warning messages appeared on the dashboard indicating traction control system service and brake system failure. These are critical safety systems. Chevrolet HE Dealership in Wichita Falls, Texas performed a diagnostic and claimed to find only a dead battery and parasitic draw. They refuse to address the traction control or brake system failures and claim they cannot duplicate the issues. They are pressuring me to accept the vehicle without written confirmation that these safety systems have been repaired. Safety Risk: A vehicle with non-functioning traction control and brake system failures is unsafe to operate. I cannot accept this vehicle until these critical systems are properly diagnosed and repaired.Than you for your help in this matter.

Engine failed on 5/8/26 with 1794 miles. Sounds like possible main bearing failure, engine had 18psi oil pressure. Signs were, knocking, banging, screeching/squealing internally from engine. No codes or check engine lights appeared. Was driving approximately 35-40 MPH on mountainous paved road. Managed to limp truck to safe pull off area and turned off engine. Had truck towed to dealership. If truck would have died on road I was driving on, it could have been bad. Road is very narrow with numerous blind spots.

My vehicle has 3416 miles on it. I was at a stop light, busy intersection, and it just died. It would not restart or go into neutral to push it to the side of the road. I had it towed to the dealership, and found out theres a bulletin on these motors. [XXX] . Why would I buy something when its been a know issue with the manufacturer since 2025. I feel as if the manufacturer is selling these units and once this happens its the consumers loss. I cannot believe the manufacturer has not issued a recall. If that were too happens there would be a lot of lemon laws and there lawyers know not to go down that road. There fix is to give me a refurbished engine!! How can that be constitutional knowing there's been a problem with this engine and now my resale value just went down. If I knew what I know now I would of purchased used because thats what im getting in return which is consumer robbery.

On April 11, 2026, my 2026 Chevrolet Silverado 1500 experienced a catastrophic engine failure while traveling on a public highway. The sudden loss of power created a significant safety hazard and could have resulted in a serious accident. I was able to maintain control and avoid a crash. The vehicle was towed to a dealership and diagnosed as requiring a full engine replacement. The vehicle has been inoperable for over 19 days, leaving my wife and me stranded far from our home in Texas.This failure occurred without warning at highway speed and presents a serious safety concern that should be investigated.

NO owner manual, etc. supplied. NO safety information supplied. NO maintenance information supplied. Dealer never mentioned when bought new vehicle on 4/22/2026. Went back next day and chevy does not supply any manuals. I could buy one for $100. if they were available. No car seat info or child restraint info. NOTHING. Did chat with GM customer service, no positive results. Asked about recall N252540430. ON owner manual being supplied. Dealer and customer service know nothing about it. I can look on phone, computer, or other digital ways to find info. Or sit in my car and use a tank of gas+ trying to find info on vehicle computer, if it is even there?

GM OWNERS MANUAL NEVER IN VEHICLE WHEN DELIVERED NEW SEPTEMBER 26,2025. DEALER SAID AVAILABLE ONLINE. GM IS RESPONSIBLE BY LAW TO PROVIDE A WRITTEN OWNERS MANUAL WITH ALL NEW CARS, SO BUYER CAN READILY ANSWER OPERATIONS AND SAFETY INFORMATION FOR THE NEW VEHICLE. PLEASE CONTACT GM TO PROVIDE MYSELF WITH A FREE, OWNERS MANUAL FOR MY NEW TRUCK. THANK YOU.

I purchased a 2026 GM Chevy Silverado. At 500 miles all dash warning lights came on while driving, radio played static. I disconnected battery in order to reset the computer. At 1400 miles in the heat of south Florida the air condition stopped working. after completing my drive 60 miles away with no ac i disconnected the battery to reset the computer. The ac started to work after this reset. I went to the dealer and they wanted me to leave the truck. They could not provide a loaner and the fact that this is my only vehicle I could not leave it. At 2000 miles the computer screen stated that there was an update. The computer would not update when I pressed start update. The screen then said unable to update conditions not met go to the dealer. I went back to the dealer and they said there is no update and they reset the computer. THIS IS GOING TO KILL SOMEONE WHEN THEY PULL OVER ON THE HIGHWAY BECAUSE THE CHRISTMASS TREE ON THE DASH CAUSED THEM TO PULL OFF THE HIGHWAY AND A SEMI IS GOING TO KILL THEIR ENTIRE FAMILY WHEN THEY ARE STOPED ON THE SIDE OF THE HIGHWAY BECAUSE GM CANNOT MAKE A VEHICLE THAT WORKS CORRECTLY. PLEASE GO AFTER GM THE COMPANY THAT STOLE YOUR TAX DOLLARS WHEN THEY WENT BANKRUPT.

Driving at highway speed’s transmission was hard shifting on its own from Drive to Low and vice versa on its own the first time. Truck taken to dealer and was told that transmission needed an update. Second time driving at highway speed experienced hard shifting in rear and felt like I was hit from behind. Lost propulsion and check engine light came on. Was told that the valve body needed to be replaced. New truck with only 7,500 miles on it. My guess understanding is that this has been an issue with Chevrolet/GM 6.2 engines. Hard shifting and loss of propulsion accord while accelerating to pass another vehicle.

Driving at 70 mph when I tried to accelerate. Heard a loud bang from the exhaust and immediately started to lose power. I had zero warning that anything was wrong. Warning messages flashed and I lost propulsion. As I was pulling over the engine died completely and shut off. Purchased the vehicle on 11/25 and had 4100 miles on it. 6.2L Chevrolet ZR2. Dealer confirmed that that the crankcase failed which resulted in catastrophic engine failure. Currently waiting on new replacement engine..

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving approximately 10 MPH, there was an abnormal knocking sound coming from the engine compartment. The vehicle was reversed to the residence and parked, but the sound was heard longer. The contact stated that while the vehicle was parked, the accelerator pedal was depressed, and the sound from the engine compartment returned. The vehicle was towed to the dealer, where it was diagnosed, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 3,134.

The 6.2L V8 engine on my New 2026 Chevy Silverado Zr2 Bison blew up around 8000 miles. While driving on highway the car shutoff and shifted to neutral while I was rolling, where I then could put it in park and restart the car to move to a safer location. Truck was towed to dealership where codes cleared during the time getting it to the dealership, and was told it was good to go. About 2 miles leaving the dealership the engine had shutoff again except did not turn on. Dealership said the camshaft had cracked and wanted to replace the whole engine under warranty.

Truck has less than 1800 miles. Was at a stop light and the vehicle started shaking and making metal tin rattling sounds. Stopped for gas, started the vehicle all noises went away. Got onto the freeway and about 1 mile down the road the truck lost power at 70 MPH. I slowed down and the vehicle continued to lose power. I put my flashers on and started to pull over and the truck died, all dash lights went black and the truck was off. I rolled to a stop and parked the truck. Called a tow truck. The vehicle wouldn’t start. It turned over at first and then nothing. I was not able to shift the vehicle into neutral. The tow truck asked me to assist while we Dragged the entire truck into the flat bed trailer. Dealer called late after noon the next day. Saying the motor was seized and had to be replaced entirely. The service technician said this has been happening to the 2021-2024 6.2L engines as well and they’ve seen plenty of them. They recalled those a used a band aid fix of replacing the oil with heavier weight and a new drain plug. He said it’s not working and all those trucks are having the same issues. He said, this was not his first 2026 motor seized in a 6.2L. He’s had another one recently low mileage that seized also. I asked for a different motor. I was told not to worry we will give you a 3 year/100,000 mile warranty. The truck was $100,000! And now they only want to warranty it for the same 3 years, just higher mileage… The motor is on back order and no telling when I’ll get my truck back. This is my 3rd Silverado and my 2017 is still going strong with 100,000 miles on it. They have a serious consumer issue on their hands and should be buying these trucks back as we will not be able to rely on the new motors. Some people have had 3 and 4 motors replaced for the 2021-2024, 6.2L engines.

I purchased my new 2026 Chevrolet Silverado 1500 truck on 12/04/2025 from CMA Chevrolet in [XXX] . When the truck was delivered, there was no owner's manual with the truck. I recently found that there was a recall associated with this issue. It is XXX. I thought that maybe manuals were now online. When I read the recall, it said that it is federal law that one be issued with each new vehicle. My VIN is not part of the recall. I contacted my salesman and he said that their parts department said that sometimes the manufacturer, GM, puts out VINs in blocks. This does not make sense. How does a manufacturer know something that they did not do?? I would like my VIN added to the list of vehicles that are affected by this recall.

BRAND NEW 2026 CHEVY TRAIL BOSS LT 6.2L V8. DROVE NORMALLY FOR 1291 MILES BEFORE THE ENGINE LOCKED UP AND VEHICLE DIED WHILE DRIVING. CHECK ENGINE LIGHT FLASHED A FEW TIMES BEFORE IT DIED. GLAD I WASNT TOWING ANYTHING YET. ONCE I COASTED TO A SAFE AREA, THE TRUCK WOULD NOT RESTART. DEALER SAID ITS THE ENGINE. NO ETA AS THEY ARE NOT AVAILABLE. VEHICLE SITTING AT THE DEALER WITH NO ETA ON PARTS. THIS IS A 2026 SO IT IS STILL UNDER POWERTRAIN WARRANTY AND NOT UNDER THE RECALL YET.

My vehicle is listed as not being affected by any current recalls. When I purchased my vehicle in December 2025, it did not have an Owner's Manual in the glovebox, which I found concerning. Why do I not qualify to receive something as important as the owner's manual under that current recall regarding that safety issue?

2026 chevy 1500 high country 6.2L with 6032 miles, engine stalled twice 3/11/2026 in one day, no check engine light no signs of anything catastrophic just simply stalled early morning commuting from work at a street light then later on same day driving with my 3 kids engine knocking/binding noise coming from engine while driving on highway stalled again leaving us stranded with engine blown on a busy offramp exit with kids under 8 in vehicle, officers arrived to guide traffic around us in a high risk environment from potentially rear ending us while waiting for roadside to recover us, truck has been towed to dealership and will most likely need new engine. no warning lights no check engine, just mysteriously and unexpectedly damaged from one minute to the next.

Vehicle: 2026 Chevrolet Silverado 1500 Incident Description: While driving at highway speed, the transmission fluid line failed and transmission fluid rapidly leaked from the vehicle. There were no warning lights, alerts, or messages before the failure occurred. As the fluid was lost, the vehicle began shutting down while still moving in traffic and stopped in the middle of the highway with vehicles behind the driver. The truck attempted to place itself into Park before it had fully stopped, and once stopped in the roadway it could not be shifted out of Park. The driver had to move the disabled vehicle off the roadway while traffic was approaching from behind. Safety Concern: The vehicle experienced a sudden loss of transmission fluid and shut down in an active traffic lane without any warning, creating a serious safety hazard for the driver and surrounding vehicles. Photos show the truck stopped in the middle of a busy highway with traffic passing while the owner documented transmission fluid pouring from underneath the vehicle. Additional photos show the dealership repair report stating the transmission cooler line was left unclipped from the fan shroud assembly, allowing it to contact the A/C compressor clutch and wear a hole in the line, causing rapid transmission fluid loss. The service manager also stated that other trucks have arrived from the factory with the transmission cooler line not properly clipped or secured. Videos available as needed. Since this incident and repair, the vehicle has continued to exhibit abnormal drivetrain behavior including shuddering and harsh or unexpected downshifts during acceleration and when using cruise control. The vehicle has been returned to the dealership multiple times for inspection, but no confirmed cause or documented successful repair has been provided.

Same problem since 2024 on the silverado infotainment center goes black, radio cuts out. The dealer is hiding this problem from the buyer and not telling them. GM has been working on this for 2 years and they can still sell the truck with an electrical problem. Lemon

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while depressing the accelerator pedal, the vehicle hesitated and failed to respond immediately. The contact stated that several seconds later, the vehicle operated as intended. A local dealer was contacted. The vehicle was taken to a dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 550.

At about 800 miles i noticed ticking from the engine and random and intermittent jerking. Some of which were very severe that felt like someone rear ended me. I took into the dealer with my complaints. They kept my vehicle for 2.5 days and didnt give me a loaner. The my were unable to reproduce the jerking and said the ticking was normal. They showed me the ticking and said its normal and will go away after it warms up. They did a vehicle update and said it will help. They said theres nothing else they will do. I knew something was still wrong but felt like they wouldnt do anything and I couldn't give up my vehicle for days at a time. I continued to drive it and was planning on taking it to a other dealer for a check up. But at about 3500 miles. One day the truck began squealing and grinding. I attempted to drive the truck home and the truck just died on the freeway. Luckily I knew something was wrong so I stayed in the slow lane so it was easy for me to get off. Thats the first time the check engine light came on but it was too late. I had it towed to the dealer and they checked and it was catastrophic engine failure.

Driving in normal driving conditions, East bound [XXX], 70 mph, tire popped off rim, no damage to tire or wheel, no apparent cause. Contacted road side assistance and they proceeded to tow to Hank Graff Chevrolet in Davison. Warranty was reported by myself to both On Star and representative at dealership.

At 4400 miles on new truck started a random cylinder misfire which engine jerking and causes ESC, Emerg breaking and adaptive cruise control to turn off. Will reset itself then do it again. Little over 100 hours on new engine. It happens on longer trips on of off the highway.

On Tuesday 01-20-2026, I was driving from Dallas Fort Worth to Oklahoma City, OK. I was driving down the highway I-35 at about 80 mph. Suddenly I felt a loss of power and my truck started to bog down. As I pulled over, the engine stalled out and would not start up again. It would crank but it would not start. My truck was towed to a dealership in Norman, OK. "Landers Chevrolet". I was contacted by the dealer the morning of 01-21-2026 informing me that my engine is going to need replaced. My truck is a 2026 Chevrolet Silverado LT Trail Boss with 6.2L and 6,457 miles on it. At this time, I don't have any paperwork or a copy of the repair order because the vehicle is still in the shop. The dealer told me that the motor is on order and should be here in 4-6 weeks. I purchased this vehicle on October 16, 2025.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 20 MPH on a dirt road in Death Valley National Park for 30 miles, the passenger’s side front shock failed, then the driver’s side front shock and driver’s side rear shock failed. There were no warning lights illuminated. The vehicle was taken to the local dealer, who declined to repair the vehicle under the new vehicle warranty. The dealer determined that the front struts and shocks had failed, and there was axle damage. The rear driver’s side wheel was also damaged. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 3,999.

Vehicle has less then 700 miles. Upon driving vehicle, the dashboard started losing information, no speedometer. When I tried to pull the truck over to the side of the road, the power steering was lost. It was nearly impossible to turn the wheel, then the engine stopped. I was unable to turn on blinkers or hazard warning lights. When I put the vehicle in park to try a restart the engine would not turn over. The transmission was locked in Park and unable to shift to neutral to try to push vehicle to safe spot. At this point I was blocking the road. Called for roadside assistance, two hours later vehicle was towed to Chevrolet dealership, were it is being assessed.

AT 150 MILES ON THE ODEMETER THE TPM LIGHT CAME ON I PULLED OFF THE HIGHWAY, GOT OUT AND CHECKED ALL 4 TIRES. NOT NOTICING ANY ISSUES I GOT BACK ON THE HIGHWAY AND TURNED ON THE STEREO. THE SPEAKERS SOUNDED LIKE THEY WERE BLOWN APART. STATIC AND THE SOUND OF MUFFLED VIBRATIONS. I DROVE TO MY INTENDED DESTINATION AND TURNED OFF THE TRUCK. AFTER FINISHING MY BUSINESS AT THIS LOCATION I STARTED THE TRUCK AND THE TPM LIGHT WAS NOT ILUMINATED. THIS IS A HIGE SAFTY ISSUE. AS A FIREFIGHTER PARAMEDIC I HAVE PERSONALLY SEEN DEAD AND MULATED PEOPLE THAT STOPED ON THE HIGHWAY AND GOT OUT TO CHECK THERE VEHICLE AND WERE STRUCK BY ANOTHER VEHICLE. THIS ISSUE IS GOING TO CAUSE PEOPLE TO IMMEADIATLY STOP AND GET OUT OF THERE VEHICLE THINKING THERE IS A FLAT TIRE. THERE IS OBVIOUSLY A COMPUTER GLITCH IN THE 2026 CHEVEROLET SILVERADO 1500 SERIES.

November 28th 2025 we were coming down Logan canyon in Utah at 50 miles an hour when i was passing another vehicle on the left I felt a hard shift and a prompt came on the dash that said reduced acceleration. So as I was passing the vehicle I was pulling in front of them and lost the ability to accelerate or even hold speed. I passed the vehicle got in front of them and slowed down rapidly without any ability to control the speed of the truck. At this point when I would push the gas nothing would happen so I pulled off the side of the road. While we were sitting, there was suddenly a burning smell in the cab so we rolled down the windows and made sure the doors were unlocked in case we had to jump out. We sat there for a minute everything seemed fine I checked the accelerator and it was working again so we drove home. I immediately took the truck down to John Watson Chevrolet to have it looked at. I told the service writer what had happened and she said there was a code that had been thrown however there was nothing now and since everything seemed fine I shouldn’t worry about it because the computers trip pretty easily on these new trucks. I insisted on making an appointment so she scheduled me for Tuesday the second of December. I took the truck in just before 730 today the second of December. Christina from John Watson checked me in and told me she would let me know when my truck is ready. She called me at 12:34 but I missed so she called again at 1:18 to tell me that she had some news on my truck and that it was going to need a new engine. I took her the dealership rental back and she sent me to enterprise for a 45 day rental. They have had the car for just over two weeks at John Watson Chevrolet in Ogden Utah.

Driving down a single lane road at aprox 30-35 MPH, when without any warnings the engine began to make a noise (like it was eating rocks), smoke began billowing out the tail pipes, the dash cluster lit up with error codes (unable to read due to attempting to get vehicle off the road), engine completely stopped, dash cluster would only show the check engine light, when attempting to get the vehicle towed it could not be put in neutral and the parking break had engaged and would not release. Vehicle was towed to nearest dealership and they confirm the engine had "seized" and would need to be replaced. Existing engine has 4190mi. If this had occurred on the highway or busy street I dont feel I could have safely gotten the vehicle out of harms way.

Engine derated when towing travel trailer putting us in an unsafe situation during heavy traffic. No warning other than display on dash reading “reduced acceleration - drive with care”. Took immediately to dealer and they confirmed “thrust bearing failure” manufacturer defect and showed us Field Service Bulletin 25-NA-307 dated 9/30/25.

Pulling a trailer down the freeway and the vehicle went into limp mode. After getting to the closest dealer for inspection, it was determined that the vehicle needed to have the engine replaced

I purchase a brand new 2026 Silverado ZR2 with a 6.2 engine. A little over a week later at 511 miles it left me stranded on the side of the road. Towed it to the dealership and the dealership advised there was a misfire and cylinder number eight. However, they were unable to find a solution and had to contact GM engineers. I had to replace it with another new vehicle and lost money on the “trade”. Dealership only advised that “it needed extensive repairs”. It’s clear that the 6.2 issue had not been addressed properly.
