WA1FVBF15KD0230442019 AUDI Q8S Line quattro Prestige

My car is a 2019 Audi Q8 3.0L V6 with only 41,831 miles. My emergency light went on and I brought it my locat Audi Dealer. The inspection revealed that the coolant pump was leaking internally, contaminating the entire vacuum system with coolant. This is not a maintenance failure or the result of owner neglect. It is a well-documented, inherent design defect in the EA839 3.0T engine platform that powers the 2019 Q8, a defect that Audi of America has acknowledged through multiple Technical Service Bulletins. Specifically, the EA839 water pump uses a vacuum-operated diaphragm to control coolant flow. When the pump's internal seals fail — as they predictably do — coolant migrates directly into the engine's vacuum system, contaminating components far beyond the pump itself. Industry experts and Audi forums alike describe this failure mode as inevitable on this platform: not a matter of if, but when. This is a design defect manifesting at a fraction of the mileage at which any reasonable owner would expect a cooling system component to fail. Audi of America has issued multiple TSBs addressing coolant pump failures on this exact engine platform, and previously extended warranty coverage for Q7 and Q8 vehicles, including those built during the same production window as the vehicle in question. Our concern is this issue can cause the engine to seize while driving and Audi's repair costs for this known issue have been quoted minimally at $5,519.76

I own a 2019 Audi Q8. The vehicle was in the dealership’s possession for approximately three (3) weeks for service. During that time, I was not informed of any significant mechanical concerns or issues. After retrieving the vehicle, it displayed an oil pressure warning while in operation. I immediately returned the vehicle to the dealership for evaluation. At that time, the dealership added oil (“topped off” the vehicle) and released it back to me without identifying or addressing the underlying cause of the warning. Following this, I made multiple attempts to have the vehicle properly diagnosed. I experienced difficulty obtaining assistance, including calls being disconnected, and I was not provided meaningful support or a thorough evaluation of the issue. Shortly after leaving the dealership, the vehicle began producing abnormal knocking noises and rapidly became unsafe to operate, requiring it to be towed. This situation presents a significant safety concern, as a sudden loss of power or drivability while driving can increase the risk of an accident, particularly in traffic conditions where maintaining speed is necessary. The condition has since been confirmed by a service provider as a major mechanical failure. Additionally, I have received documentation from the manufacturer indicating a known issue related to piston skirt defects associated with this vehicle. Despite the vehicle being in the dealership’s possession for an extended period, this issue was not identified, diagnosed, or addressed. I was also not provided clear assistance or guidance regarding potential warranty consideration related to this known issue. The vehicle is currently available for inspection upon request.

Piston slap issues. The manufacturer is aware of the engine failure issues. They extended the engine warranty coverage from 50k to 80k miles knowing that the engine piston slap is an extreme issue but they won’t issue a total and complete recall. Owners have to identify that issue and have to specifically bring it in to have it bore scoped. If an owner isn’t aware of the noise and goes over the 80k miles then they are not held responsible for the complete and utter engine destruction.

Due to a leak in the rear axle that is connected to the differential, it caused the entire differential to fail. The bearing within the differential completely failed due to contaminated oil. The Q8s are known to have this occur but only in year models 2020-2022. My Q8 is a 2019 and Audi is aware of these issues given technical service bulletins available but doesnt want to take responsibility as this may be a continuing manufacturing issue arising. My vehicle only has 65k miles on it and Audi admits this is rare. Due to a misdiagnosis in June of 2025 (oil leak), Audi of Seaside Monterey caused the complete failure of the differential in December of 2025 by not doing a deeper diagnosis earlier to resolve the catastrophic failure. This is a safety concern and very expensive. A new differential costs $12k which has been expected to pay with no accountability. I am currently in an active case with Audi Seaside and the BAR to come to a resolution.

Dash Delamination: The leather dashboard is experiencing severe delamination and pulling away from the substrate, specifically in the area surrounding the passenger-side airbag. I believe this condition poses two significant safety risks: Airbag Interference: The detached and warped material may obstruct, delay, or alter the deployment path of the passenger-side airbag during a collision. Visibility and Distraction: This is a material defect, not wear and tear, and it poses a potential safety concern due to the reflection/glare on the windshield, as well as the distraction it causes while driving. Audi has acknowledged this "process weakness" and issued a Limited Warranty Extension (AWA-23-11) for 2019-2020 Q8 models. Despite this, my request for a safety-related repair was denied due to over 80K. The issue should be considered under mileage. I am requesting that the NHTSA investigate this defect to determine if it constitutes a safety non-compliance with FMVSS No. 208, as the structural integrity of the dashboard is vital for proper airbag performance. Thank you for your assistance in ensuring the safety of this vehicle.

I was having noise from engine and and I received a letter from extended warranty for an production defect in piston skirt. I sent my car for an evaluation in the Audi of Manhattan and I was told that my car falls under the engine piston skirt defect.i have the pictures from Audi Manhattan inspection that the engine piston walls have scratches.i was denied coverage under extension warranty because my car was over 1752 mile over the extension warranty.this is and production engine defect and can be stranded any time soon in the high way or any other street putting me and My family in danger and any other people driving around my car if that engine stops in the middle of the street. My car has 81752 miles and the extension warranty was up to 80000 mile or 8 years. The extension warranty came to late almost after 6 years ,as this is an known problem with those engines EA839 that is found in audis Porsche VW Tuareg ect.

Faulty water pump → allowed coolant to migrate into the vacuum lines (a place coolant should never be). •This led to turbo underboost faults (loss of power) even though the turbo itself is fine. •The contaminated vacuum system now requires replacement of the vacuum shut-off valve and possibly other vacuum components. •Because of how the parts are placed, the repair requires removing the front bumper, and once it’s reinstalled, the safety systems/sensors must be recalibrated.

engine begin to misfire and felt like it was ready to stall. within a minute of the misfiring the engine light came on. i was in the middle of highway struggling to get my vehicle to the dealership where purchased which thankfully was only 5mins away. tech heard noise coming from fuel pump near the engine and recommended replacing along with spark plug. after replacing tech advised me to take my vehicle to audi to perform a software update that will correct the misfire and prevent the MIL from illuminating. Got that done to only be presented with a knocking noise again a month or two later. Took my car back to Audi to run a full diagnostic to find out my engine is in early engine failure due to metal shavings in the oil filter. tech states shavings in the oil could originate from the fuel pump failure and the debris would have traveled into the engine oil causing critical damage to the engine.

being quality Engineer, why is this thing failing , and why are there no recalls? Amazing how they design these things to fail right at 50k miles. From what I hear, the audi's are notorious for not making these replacements simple and specialized tools are needed. I wouldn't change anything engine related unless you have issues like engine shaking, or rattling sounds stemming from the engine mounts. And if you get major work done, it is probably best to go to the dealers and pay the extra to make sure it will be taken care of properly! numerous same issues engine mounts after 50k MIles

There is helicopter type of noise coming from fuel pump and it’s increasing while driving very annoying and i feel steering is loose and I notice on google same problem with so many Audi q8 and sq8

Wheel arch on the front passenger side flew off on the highway. There was no visible issues that the piece was loose as it’s been on the car securely for 45k miles.

2019 Audi Q8 3.0T quatro with 34,102 miles incurred broken left rear coil spring. Right rear most likely will have to be replaced soon. A SUV of this age and mfg shouldn't be having broken coils. This defect appears to be happening quite often. From the dealer's quote... "Recommended service: Coil Spring Replacement - Rear: LEFT REAR SUSPENSION COIL SPRING IS BROKEN (SEE VIDEO ATTACHED) RECOMMEND REPLACEMENT OF BOTH REAR SUSPENSION COIL SPRINGS AT THIS TIME. Suspension coil springs support the weight of the vehicle and determine the height at which it sits on the road. The springs allow the suspension system to move and adapt to changing road irregularities; they are under extreme pressure. $2,562.60"

I was smelling fuel from my car so stopped to have it checked and was told there is a significant spray of fuel coming from the fuel rail and hitting the electrical wires. I was told that it could go on fire at anytime and the car cannot be driven. Audi has a recall for this exact issue for 2016-2018. This is clearly the same issue but they are not issuing a recall for 2019 models and it’s extremely dangerous.

Air conditioning failure, evaporator failure; known issue with Audi Q7, Audi Q8 not included in limited extended warranty

The contact owns a 2019 Audi Q8. The contact stated that while driving at an undisclosed speed, a central locking malfunction warning sign was displayed. The contact stated that later when a rear passenger attempted to exit the vehicle, the door failed to open. The driver’s and passenger’s side rear doors failed to open. The vehicle was taken to a dealer where it was diagnosed with a failure related to Technical Service Bulletin: DTC B14FF29. The vehicle was repaired under Warranty. The contact stated that the failure reoccurred, and the dealer was made aware of the failure; however, the contact was informed that the vehicle was no longer under Warranty. The vehicle was not repaired. The contact stated that it was a known failure. The manufacturer was made aware of the failure and advised the contact to have the vehicle diagnosed before any assistance would be provided. The failure mileage was approximately 9,800.

The alternator failed causing the vehicle to shutdown in the middle of traffic. I was on a surface road not the highway so I was able to get local police to assist. When it failed there was no car electrical system function, so I could not even turn on my emergency blinkers. This is apparently very common on Audis, as the same part was used to replace the alternator…. It took a month for the dealership to get the part in stock.

I was driving home from work when all of a sudden I got error messages: Electrical system malfunction! Please contact service; Start/ stop system: malfunction! Function unavailable. Please contact Service, yellow battery light and the car died. None of the safety features, locks, engine, or air condition worked and the car had to be towed to the dealership. Within 1 mile of the lights appearing the car died, putting my safety and those on the road at risk. I left in the middle of the street and had it towed a few hours later. I spoke to the dealership and was diagnosed and confirmed as a alternator- starter-generator issue and reading the Audi threads it is a common issue. The car has about 38,000 miles. I am the second owner and have had the car for less than 6 months and it has been well maintained.

Car makes creaking sounds when going over bumps and turning left or right.

While driving down the freeway to the dealership a electrical system malfunction message came across the display. I continued on to the dealership and suddenly started getting system failures. One by one it popped up and said every single system failure including brakes and steering system malfunctions. Then it said transmission malfunction and I immediately lost all forward propulsion. The engine just revved when I hit the gas. I had to fight my way over to the shoulder where the vehicle came to a stop and would not even let me set the parking brake or engage park. I sat I the vehicle on the freeway between an on ramp and the moving lanes until the tow truck showed up. The failure turned out to be the alternator which I'm told is a very common issue for most audi vehicles. The vehicle was towed to the dealership and they replaced the alternator at no charge due to an extended warranty already granted on the failing alternators. The repair was made and vehicle was returned but the same alternator was put into the vehicle that was in it originally as it has not been updated. This created a major safety risk as power was lost while traveling at freeway speeds.

My 2019 Q8 has less than 35K miles and has had breaks and rotors repaired three times and needs them again. The breaks pulsate and wear down at an excessive rate, the stock breaks are not a good enough product for the weight of the vehicle. I’ve raised this issues with the dealership multiple times and this is my 2nd Audi SUV with break issues.

Electrical malfunction displayed on dashboard with every system in the car shutting down within seconds. I was stranded on the freeway shoulder. Maybe an issue with the alternator.

While driving warning light came on electrical malfunction on highway cat lost all power following a series of light’s indicting multiple malfunction then transmission disengaged I was able to coast to a stop , was unable to get out of vehicle due to car not unlocking

Car showed “electrical system malfunction” while driving. Said that the start/stop system failed. Proceeded to say that the rear brake light not functioning while driving, which would pose a safety risk to all drivers and myself.

Purchased in 12/22. Electrical System Malfunction was alerted on 11/7/2023. On 11/8/2023 car shut off, and would not start again. Battery is completely dead, and mechanic says it’s an Alternator issue. Part is on international back order for at least 2 months. Audi knows of this issue and is still selling these cars. Will not provide loaner, and has multiple vehicles sitting on lot waiting for part.

Alternator/generator failure at 55910 miles

While driving the vehicle to work, several warnings came on saying there was a system issue and to pull to a safe spot. The car was pulled off the main traveling lane into a turning lane where it died. The electrical system did not work at all. The hazard lights could not be put on. The prior day the auto stop light came on saying there was a malfunction with that. The dealer was contacted. They said it was fine to drive. The car is currently at the dealership.

May 19th water pump cooling system pump my wife driving right on a highway on a left lane car start streaming and engines suddenly shut off thank God she make it to the left on hwy we throw the car to dealer they says engine went because of water went to engine and after that I have a big issue with the dealers and everything even my insurance pay for the new engine and everything and this is the issue a woman driving this car this is so much risk audi not doing anything about it

Electrical malfunction warning light and assorted other warning lights came on during acceleration on highway. Loss of car functions due to error. Car is waiting on parts due to failed belt start generator as part of its 48 volt mild hybrid system.

While driving 35 mph car electrical system started to shutdown. Red warning message came on immediately followed by car turning off while in drive and car was moving.

I have a 2019 Audi Q8 with 39k miles. I just received an indication stating that an electrical issue has occurred and to contact service maintenance. While on my way home from work with the electrical issue active the air conditioning stopped working which appeared to be unusual. I was able to still drive the vehicle home. I then searched on Google about the issue and read numerous complaints through various forums regarding the issue. Most of these issue were similar to my experience. Also these complaints were around the same year and mileage of my vehicle. Please help to have Audi resolve this issue.

Driving vehicle at a low/medium rate of speed, and car completely shut off without warning. Check engine light appeared after restarting the vehicle. This is the second time this has happened to me since November 2022. I filed a report then as well. This car should not be allowed on the road and Audi should be forced to buy it back. The vehicle has less than 35,000 miles. Dealer has not confirmed what the issue is this time.

I am the owner of a 2019 Audi Q8, purchased on 8-8-19. I have had repeated issues with the driver's side seatbelt twisting and retracting the twisted portion up into the B pillar. I have had this issue repaired 3 separate times at my local dealership, most recently in June of 2023. Just 2 weeks after having it repaired, it twisted for the fourth time in early July. It has therefore been witnessed and documented by the dealership each time it has been repaired. The issue has never happened to me and has always happened after my husband has driven my car. So I cannot tell you what exactly is happening to cause this. There is a TSB regarding this problem. It is NHTSA ID Number: 10233615 published on 3-29-23 (the original TSB was NHTSA # 10158643 published on 4-1-19). The Manufacturer Communication Number: A6923872058455_6 I am concerned that there could be a safety issue while the seatbelt is in this twisted state. Thankfully I have not been in any accidents/incidents where the seatbelt malfunctioned. But how can I confidently be assured that the seatbelt will continue to function properly? It is not normal for a seatbelt to due this. I contacted my dealership on July 21 to have it repaired again under warranty, but they told me that I would have to pay to have it fixed again. They claim that it was never covered under warranty and that they repaired it each time for free. This was the first I had heard that is wasn't covered under my warranty. I escalated this issue to Audi of America, reference #05805277. I heard back today that the dealer claims "outside influence" as the cause of this seatbelt problem. Therefore, they will not repair it as it does not constitute a manufacturer's defect. I do not feel safe driving with my seatbelt in this condition. I am hoping that the NHTSA can guide me in the right direction for a resolution to this matter.

Electrical system malfunction caused the car to come to a stop in the middle of a busy highway. The vehicle needed to be pushed off to the side of the road by other parties as steering became increasingly difficult to navigate to the side of the road. The vehicle was stuck in neutral and could not start the engine to drive again. The vehicle needed to be towed to the closest dealership for further investigation.

Car started flashing all kinds of warnings, then cut off and had to coast to the side of the highway. Then could not get out of the car and the entire system was in complete failure so the doors would not open. Absolutely terrifying experience. Audi knows this is a bad issue and it keeps happening to thousands of Audi owners with the mild hybrid system.

2018 AUDI Q8. CONSUMER WRITES IN REGARD TO ENGINE FAILURE.

48v mild hybrid system failed, car went completely dead in rush hour traffic putting me and other drivers in danger.

Electrical malfunction illuminated on the dash than brake malfunction illuminated than the vehicle lost all power no power to windows locks but I was able to roll off an exit and waited for a tow truck to tow to nearest dealer

November 18, 2022 a warning lamp of electric system problem was displayed. There is no local Audi dealer and I decided to take the vehicle to my local automotive repair shop that does non warranty repair on Audis. I drove approximately 6-8 miles after the light came on and was one half mile from the service technicians when within 300 yards the vehicle became sequentially inoperable. First power steering, then transmission, brakes , ended with engine failure. I was in rush hour traffic and unable to steer off the road so I was blocking traffic near an intersection. My flashers and power windows were all that functioned. The doors were locked. When the tow truck arrived he let me out of the car. I was not injured and the vehicle was not hit either. The vehicle was transported to Audi Beaverton Oregon and now 3 1/2 months later is still there because there are no available starter/generator units available in this country. That unit failed and was the cause for my Audi’s complete shutdown. This was a potentially very dangerous situation and needs to be reported for a recall campaign. I have read that there are thousands of similar failures of the starter/generator systems in the USA and no available parts. I still have no estimate from my Audi Beaverton dealer/sevice supervisor as to when I can expect to get my car repaired and returned to me. They have not provided a loaner vehicle and refuse to cover the full cost of a rental car. I am disappointed in Audi’s level of customer service and communication.

2019 Audi Q8. The car is back in the Dealer Shop for almost 2 months. We don't really know what is wrong with the main issue on ALTERNATOR OR 48 V battery problems. And the excuse Service gave us is No ETA on the Parts From Germany. They have new cars coming in and they don't have parts coming in??. We are stuck in the middle, can't trade in or sell our cars. Right now this Q8 is a huge junk without any functional purpose. Some of the owners have been waiting for this fix for 3, 4 months. The government really should step in to find out what is going on on AUDI. It can't be parts shortage. It is some problem what AUDI simply can't fix. AUDI USA is also very unreliable. They direct us to our individual dealer, saying they can't do anything about it. They don't take any responsibly. We have no one to file complaint to.Most of the cars are still in the warranty, it is simply unbelievable.

On 12/12/2022 I was driving and the Q8 lost power and I coasted to a stop. All lights on driver panel were flashing or sequencing through. After sitting on the side of the road for 5 or so minutes I tried starting the car again. This time it started and I drove another 8 miles almost to my home when the car again just died in the road. This time I couldn't get it to restart. I had to have it towed to my local garage as my dealership was an hour and fifteen minutes away. The car has been diagnosed with needing an alternator, which no one including the dealerships have because this is a problem with many vehicles. It has now been over two months without my car.

In September 2022, I contacted the dealership to schedule my 50k service after observing a yellow battery light indicator flash on and then resolve itself by turning off. The mileage on my Q8 was approximately 44K at this time. I was also experiencing a passenger seatbelt warning issue despite no one in the passenger seat. The soonest the Audi service department could get me scheduled was on February 14, 2023. This has been an issue with Audi service departments at least the past 2 years. Since scheduling, I've experienced the warning issues several times On Thursday, February 2, 2023, I got a flashing yellow battery light in addition to other warnings that flashed on and then off. Because of this, I decided to take my car to the dealership for an emergency service on Friday, February 3, 2023, before traveling out of town the next week. While enroute to the dealership, the instrument panel alerted to an electrical system malfunction by displaying a yellow and then red battery icon. Multiple other warning lights for other systems malfunctioning displayed and the car stopped in traffic. My car was towed to the dealership. Once at the dealer, I was told that this was due to the generator failing and the part is on backorder due to being manufactured in Ukraine. The dealership stated this failure is apparently widespread, citing 56+ cars at this dealership and 100+ at the other with the same issue. Based upon this, the dealership informed me I qualified for the Audi USA buyback program and to contact them for a case number. When I called, I was told I had to wait 10 days to file or have had 3 reported incidents on record. On Februrary 14, 2023, I was told I did not qualify because my car was over 50k at the time it broke down. My mileage is 54,128. The issue began before 50k. I learned from the dealership, I qualify for the buyback because Audi extended the factory warranty on 1/31/2023 to include unlimited miles. I have an audio recording.

2019 Q8 with 48 V battery problem which causes the Alternator failing. The car is in shop for a month, without any ETA on parts coming in. Audi knew this issue without any plan B. My shop told me there are cars with same issue sitting in the dealship shop waiting for parts since Oct 2022. Today is Feb 10 2023.

System malfunction warning appeared. 5 miles after the warning the car stopped working. Stirring is unresponsive.

Got Electrical System Malfunction to start. I called service and they said car was safe to drive. Continued driving got a fault for automatic start/Stop malfunction, followed by: Right lug nut loose Right brake light malfunction Parking brake malfunction Distance indicator malfunction Power Steering malfunction Drive train ,malfunction. Car engine started hesitating and dash went totally blank. Car was hard to steer , luckily I live near the dealership. Dealer said there are 30 cars in their service department with the same problem. I am #3000 on Audis waitlist for parts to fix problem. 48 volt battery and alternator.

The car completely shut down in the middle of traffic with an electrical system malfunction and safety system malfunction.

Alternator/Ignition Generator died while driving vehicle causing vehicle to die in the middle of the road.

Generator failure. Car has been at the dealership for 45 days. Waiting for a replacement at a cost of $4000??

My alternator failed with "electrical malfunction" alerts until the car decided to shut down on the highway with my newborn and wife. The bigger issue is I'm being told there is a national shortage for this part with no ETA on receiving the part and that it could be MONTHS until they receive the alternator replacement.My car is in dealership since Dec 6 2022. Today is 01.10.2023

Electrical malfunction warning light. Vehicle stop and was steering wheel locked and then unlocked. Then stated ok to steer but steering was very hard. No power. Multiple systems fail warnings lights. Alternator is what they have stated. No part available. They currently (from what the service dealer states they have approximately 15 cars waiting). One dealer The issue is the in-operability of the car. Just stops which is highly worrisome.

While driving in heavy traffic on 12/23/22 the entire electrical system shut down and all power was lost. Fortunately I was not hit by another vehicle and coasted into a parking lot with no power. This is very dangerous. Per conversations with the dealership and with Audi (1/10/23), alternators on thousands of vehicles are failing (possibly due to a software issue). The vehicles are sitting on dealer lots and in driveways useless. Audi online forums confirm this as well. There are no alternators available. No recall has been issued and no warning of this unsafe situation has been made by Audi. Per the dealership, they are largely in the dark as well as there has been no meaningful communication by Audi. Someone will get hurt when their car dies on a highway. People are paying thousands for their cars to be undrivable. Audi dealers will not trade the vehicles because they are effectively worthless until repaired.

The Generator (Part #: 4N0903028P) failed causing the car to shutoff while driving. This is a known issue by Audi as it has issued a TSB. Further steps must be taken by the OEM to ensure safe operation of the vehicle by its owners. This is a safety issue that must be resolved soonest!

Vehicle lost all power and control while driving 45mph. First electrical system failure warning came on. Within 2 minutes the transmission slipped into neutral and 15 seconds later the vehicle lost power and I coasted to a stop. I was told by Audi dealership service that the starter generator failed. They mentioned they currently have over 20 vehicles in their shop and over 25 at their other location with the same problem. They also said over 1,000 cars nationwide had same problem and the part to repair is back ordered and no reasonable estimate of repair time.

Critical Failure - Alternator/48v Generator Issue in Audi Q8 Prestige. By now, I am well aware that the problem I'm experiencing is in the top 25 repair issues for Audi and currently there are 15,000 cars affected in the United States according to my dealer, waiting for these parts. Out of nowhere while driving on an interstate, at a high speed I got all mix of signals and the amount of time to react between the first sign that something is going wrong to the "stop operating the vehicle and pull over to the side message" and vehicle shut down, without ability to start is within just few minutes from each other. First I get a random battery error message. Battery light had popped on the dash panel. Then, system malfunction message, the whole array of different malfunctions. Noticed odd things like the auto start/stop not enabled and about 10 others error messages in regards to every system in the car. Then the speed sign sensor wasn't working, like limp mode, then the lane departure went, then the traction control system went, then the transmission something went off. I couldn't possibly make it to the dealer from that point, it was only few minutes and It told me to pull over to the side. Car would not start again, the panel wouldn't light up and only weird stuff, like windows would go up and down as I try to start the vehicle.  Had to tow vehicle to the dealer (Car is still under the original warranty). Was notified that the alternator is out and needs to be replaced. There is more to it, that part is on the back order all across the US and there is no estimate on when they're going to get it. No solution been provided and every dealership in the State has multiple vehicles awaiting for this same part. 

alternator failed, multiple electrical/ computer systems shut down, eventually left me stranded.

Electric System Mal Function. The Car was flashing all signals. It asked to pull over and said there is a danger of car turning over. We called audi assistance. The tow truck driver could not load the car as the wheels were all locked up.

48v Starter Generator went bad. Vehicle shut down on the high way. I have been without my car for nearly a month as the part is on back order, and there is no ETA for the part.

Driving down the road when sensors stopped working. Car read electrical system malfunction and engine shut down. Had to coast to the shoulder. This is a known safety issue, and should be completely recalled.

An "Electrical System Malfunction" warning, check engine light and the battery light came on. Was informed to notify service. Few hours later multiple system failure started to appear. Dashboard went dark and I was unable to tell the speed of the vehicle. The window rolled down on it is own. After coming to a stop the vehicle was unable to start again. Dealer informed me the "affected parts" are being ordered. No further updates were available.

While driving, all the warnings came on the dash. "Electrical Malfunction", "Child seat belt malfunction", "Start/ stop malfunction", "Steering Wheel malfunction" "Power Brake malfunction" and when I came to a stop, the car completely stopped. I could not put it into neutral to push it out of the road so my car blocked a lane on a highway making it very dangerous. 2 service reps from 2 different Audi dealerships have confirmed that is this a known defect with the v48 generator/ alternator

The contact owns a 2019 Audi Q8. The contact received notification of NHTSA Campaign Number: 22V516000 (Fuel System, Gasoline) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

The contact stated while driving at an undisclosed speed and then stopping at a traffic light, the vehicle stalled. The contact stated that he restarted the vehicle several times however, the failure recurred several times. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was approximately 36,700. VIN tool confirms parts not available.

Rear middle light (brake) bar that attaches to the rear trunk cracks repeatedly. Has been replaced twice by Audi Indianapolis under warranty. Third middle brake light has curing issue with plastic that causes light to crack on its own. Part has been sent back to Audi for inspection on the first replacement ; however, even the second replacement has now begun to crack. In time this will affect the middle brake light from functioning. 2019 Audi Q8 current mileage ~7000 miles.

I was driving yesterday on a highway and the car completely shut down. Got stranded in the left lane with 4 kids in the car - could have been killed. I had previously brought the car into the dealer for a fuel pump related issue. Apparently there is a recall but they don't even have the part to fix it.

1.STEERING WHEEL MALFUNCTION: sudden loss of steering control increases risk of crashing. Steering wheel now feels more loose. Issue is listed under recalls for 2019 Audi Q8 SUV's. Yellow warning light (triangle with exclamation point), Loud " dinging" alert. Appeared 10/13/2022. 2. CENTRAL LOCK MALFUNCTION: randomly unable to lock or secure vehicle. Vehicle & belongings open to public theft & damage. Central lock malfunction message appears on dash. Appeared 10/12/2022.

I purchased a used 2019 Audi Q8 Prestige Plus, with Sportline Pkg on 9/7/21. Car had approx. 18,500 miles. The car attempts to shut off when deaccelerating at any speed below 3000 rpm. There is also a significant throttle delay between the time you push the gas pedal and when the engine responds. To be clear the car is in Dynamic mode and the Start/Stop mode is deactivated. It appears that under certain conditions the car is trying to determine if it should shut down or continue running. The Audi 37M6 update has been performed on my car which was supposed to correct the problem. The Audi Knoxville Shop Foreman drove the car and experienced the problem, contacted Audi Technical Assistance center (case# HS-822562) and was told that the car had the latest software correction. The Shop Foreman wanted to erase the transmission clutch adaptations to see if the car could relearn the shift process but was advised by Audi Technical Assistance not to erase the transmission clutch adaptations and would not allow the Shop Foreman access to the car software in an effort to diagnose the problem. Note: there was a class action lawsuit in May 2020 for this problem that was dismissed because the car manual states the car can experience a delay when restarting from the Start/Stop mode. However, my issue occurs when the Start/Stop system is turned off. There is no continuous throttle response below 3000 rpm with the Start/Stop system turned off. I was given a 2021 Q7 with a 2.0 as a loaner car while my Q8 was in service and I did not experience any of the issues I have with my Q8. I was advised by my dealership to also write a letter to Audi USA as the dealership acknowledges there is a major problem and they want to try fix the issue but will not be given access to the car software to troubleshoot the issue. This is a dangerous problem.

The auto start/stop feature of this vehicle is horrible, on several occasions I've almost gotten into an accident turning at an intersection. The engine loses power for 2-3 seconds despite pushing the gas pedal all the way down. I've also scared pedestrians at cross walks on several occasions when the vehicle is at a full stop but then suddenly lunges forward at them. The sensors on this vehicle are also very faulty. The ones that are supposed to open the rear hatch do not work despite me waving my feet and hands under them for several seconds at a time. The key fob also doesn't open the rear hatch like it's supposed to. And the sensors to detect objects around the perimeter go off all the time without any apparent reason. I've had the vehicle in for multiple service visits and none of these issues have been resolved.

The contact owns a 2019 Audi Q8. The contact stated that while attempting to exit the vehicle by pulling the interior door handles, the doors would not immediately open. The failure had occurred on the front driver and passenger side doors along with the rear passenger door. The cause of the failure was not determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 16,000.

The spare tire is stored deflated and must be inflated for use. The factory tire pump overloads the circuit and blows a fuse. For all practical purposes, my vehicle was shipped without a spare tire which is a significant safety and security issue. This failure has occurred twice during roadside emergencies (loss of tire pressure). My dealer technician confirmed and recreated the circuit overload but offered no 'fix'. There are reports in online forums of similar experiences and the 'fix' appears to be replacement of the factory tire pump. My dealer has not been cooperative / timely with this proposed 'fix'.

I'M VERY UPSET WITH NHTSA AND AUDI. I SUBMITTED A COMPLAINT WITH NHTSA ON 10/22/20 AND THE COMPLAINT NUMBER IS 11365744. AGAIN AS STATED IN MY COMPLAINT THIS IS AN ACTUAL SAFETY ISSUE. I THEN TOOK THE VEHICLE INTO THE DEALERSHIP FOR THEM TO LOOK AT THE PROBLEM. WELL IT TURNS OUT THAT THE DEALERSHIP'S SERVICE DEPARTMENT HAS HAD A NUMBER OF COMPLAINTS JUST LIKE MINE. IT ALSO TURNS OUT THAT AUDI HAS A FIX FOR THE PROBLEM. THE FIX IS A SOFTWARE UPDATE 37M6. I'M GLAD THE ISSUE HAS BEEN FIXED ON MY VEHICLE BUT THE REAL ISSUE IS THAT NHTSA AND AUDI ARE AWARE OF THIS FIX BUT BOTH OF THESE ENTITIES ARE NOT REQUIRING THE FIX TO BE MADE VIA A GOV'T ISSUED RECALL. AUDI CALLS THIS FIX A "CAMPAIGN". AUDI IS AVOIDING THE STANDARD PRACTICES OF NHTSA BY REFERRING TO THIS PROBLEM AND FIX AS A CAMPAIGN WHICH IS OUTSIDE OF THE NORMAL TECHNICAL SERVICE BULLETIN AND SAFETY RECALL PROCESS. HAS NO ONE AT NHTSA OR AUDI LEARNED THE LESSONS OF THE GM DEBACLE WITH THE IGNITION SWITCH. THIS COVER UP BY NHTSA/DOT AND AUDI IS A COMPLETE AN UTTER DISGRACE. TO ALLOW AUDI TO OPERATE OUTSIDE OF THE NHTSA SYSTEM IS A COMPLETE FAILURE. NHTSA NEEDS TO MANDATE AUDI ISSUE A SAFETY RECALL ASAP!

OUR A8 HAS ISSUES WITH LAG TIME WHEN ACCELERATING FROM A STOP OR A SLOW SPEED OF LESS THEN 10 MPH. THE VEHICLE SEEMS TO STOP RUNNING PRIOR TO A FULL STOP AND IF THE ACCELERATOR IS DEPRESSED NOTHING HAPPENS FOR ABOUT 5 SECONDS. THIS IS EXTREMELY DANGEROUS AND LEAVES US AT RISK OF BEING INJURED OR KILLED. THIS ISSUE STARTED JUST A FEW MONTHS AFTER PURCHASE AND HAS GOTTEN CONTINUALLY WORSE. WE HAVE ALSO ENCOUNTERED THIS ISSUE EVEN AFTER A FULL STOP AND THEN TRYING TO ACCELERATE FROM A FULL STOP. IT HAS EVEN HAPPENED WHEN DRIVING ON AN INTERSTATE HIGHWAY WHEN TRYING TO PASS ANOTHER VEHICLE. THE DELAY IN ACCELERATION IS VERY DISCONCERTING AND DANGEROUS TO SAY THE LEAST.*DT*JB

AFTER MOST RECENT SOFTWARE UPDATE, THE BACKUP CAMERA DOES NOT AUTOMATICALLY ENGAGE OR DISPLAYS A BLACK SCREEN. THE BACKUP CAMERA PREVIOUSLY WORKED FINE. OTHER TIMES, IT WILL DISPLAY THE FRONT FACING CAMERA INSTEAD OF THE REAR CAMERA DESPITE BEING IN REVERSE.

EVERY TIME IT RAINS THE TECHNOLOGY SENSORS MALFUNCTION EX: THE BLIND SPOT, LANE CHANGE ASSIST, INTERSECTION ASSIST, AUDI PRE SENSE, AND REAR CROSS-TRAFFIC ASSIST. ALSO THE CENTER CONSOLE HAS BLACKED OUT OF A FEW OCCASION WHEN THE VEHICLE WAS IDLE AND MOVING. AND OVERTIME I HAVE BROUGHT IT IN FOR REPAIR AND SHOWED THE VIDEO, THEY STATE THE DIAGNOSTIC DOES NOT PICK UP ANY ERRORS AND THAT THE VEHICLE IS PERFORMING PROPERLY DESPITE THE VIDEOS I HAVE PROVIDED. THE FINAL RESULT IS ALWAYS THEY HAVE PERFORMED A SOFTWARE UPDATE!

I LEASED THIS 2019 AUDI Q8 IN DECEMBER 2018 FROM MY LOCAL AUDI DEALER AND IT HAS HAD SO MANY TECHNICAL ISSUES FROM THE START. I'VE HAD IT IN FOR SERVICE ISSUES 5 OR 6 TIMES. IT KEPT SHOWING THE OIL SYMBOL AND SAID THERE WAS TOO MUCH OIL AND WAS CHECKED AND THEY SAID IT WAS JUST A COMPUTER ISSUE. THEN THEY REPLACED A PART AND IT HAPPENED AGAIN NOT LONG AFTER. THEY THEN CLAIM THE REPLACEMENT PART WAS FAULTY. SINCE THE BEGINNING, IT HAS HAD ISSUES ACCELERATING WHEN IT IS IN THE ENERGY SAVING MODE, WHICH IS DEFAULT AND YOU HAVE TO DISABLE IT EVERY SINGLE TIME YOU USE THE CAR. THE CHECK ENGINE LINE HAS BEEN ILLUMINATED MULTIPLE TIMES AND WHEN SERVICED, THEY CLAIM IT IS SAFE TO DRIVE AND THAT AUDI IS WORKING ON A COMPUTER FIX TO THIS PROBLEM. NOW THE "DRIVE SYSTEM: MALFUNCTION! PLEASE CONTACT SERVICE" LIGHT IS CONSTANTLY ILLUMINATING AS IS THE CHECK ENGINE LIGHT (PICTURE ATTACHED). THIS IS BY FAR THE MOST EXPENSIVE CAR I HAVE EVER HAD AND IT HAS HAD MORE ISSUES THAN ANY OTHER CAR I HAVE HAD. I'M NOW VERY CONCERNED THAT I AM PUTTING MYSELF AT RISK FOR DRIVING THIS CAR.

THE CAR WILL UNPREDICTABLY LOSE ALL POWER FOR 2-3 SECONDS. THIS HAS MORE THAN ONCE NEARLY CAUSED A FATAL ACCIDENT!!!!!!! THE MANUFACTURER IS AWARE OF THE PROBLEM BUT UNABLE OR REFUSING TO FIX IT. PLEASE SAVE LIVES TODAY AND RECALL THE CAR.

WHEN DRIVING IN ANY STANDARD DRIVING MODE, WHEN YOU START TO COME TO A STOP WITH AUTO S/S ENABLED (E.G. SLOW DOWN) TO LESS THAN 6MPH, THEN ACCELERATE AGAIN, THERE IS A CONSIDERABLE LAG FOR THE VEHICLE TO START ACCELERATING AGAIN (ABOUT 1-2 SECONDS). THIS IS ESPECIALLY DANGEROUS WHEN MAKING LEFT TURNS WHEN THERE IS CROSS TRAFFIC AS THE VEHICLE OFTEN DRIFTS INTO THE INTERSECTION AND YOU CAN'T QUICKLY ACCELERATE AWAY. HAVE HAD MANY CLOSE CALLS AND THE ISSUE IS EASILY REPLICABLE ON ANY 2019 Q8.

AUTO START/STOP IS SO LAGGY WHEN RE'STARTING THE ENGINE, ESPECIALLY AT LARGE CROSSINGS W HEAVY TRAFFIC OR ROUNDABOUTS. I HAD ALMOST 5 ACCIDENTS IN THE PAST YEAR BECAUSE YOU ANTICIPATE ONCOMING TRAFFIC AND FROM EXPERIENCE YOU KNOW YOU CAN EASILY TURN OR GO, AND THEN YOU JUST ROLL A BIT AND THERE IS NOTHING HAPPENING AND YOU HAVE NO CHANCE TO DO ANYTHING.

WHEN START/STOP SYSTEM IS ENABLED, THE ENGINE WILL SHUT OFF WHEN COASTING TO A STOP. IF YOU TRY TO ACCELERATE IT TAKES 2-3 SECONDS FOR THE CAR TO ACCELERATE. THIS IS EXTREMELY DANGEROUS ON LEFT HAND YIELD TURNS WHERE THERE IS ONCOMING TRAFFIC. THIS PROBLEM CAN BE SOLVED BY TURNING OFF THE START/STOP SYSTEMS OR PUTTING THE TRANSMISSION INTO SPORT MODE WHICH WILL AUTOMATICALLY TURN OFF THE START/STOP SYSTEM. IN ADDITION, THE CAR DOES NOT REMEMBER YOUR SETTING WHEN THE CAR IS TURNED OFF. SO EVERYTIME YOU START THE VEHICLE YOU HAVE TO REMEMBER TO TURN OFF THE START/STOP SYSTEMS. AUDI DEALER ASKNOWLDEGED THE ISSUE AND PERFORMED UPDATE, BUT THE ISSUE STILL PERSISTS.

THE VEHICLE HAS MAJOR THROTTLE LAG FROM A STOP STATE OF THE CAR, IF YOU ARE NOT AWARE, THE VEHICLE WILL LAG ON ACCELERATION AND SUDDEN JERK FORWARD AT FULL SPEED WHICH IS A MAJOR SAFETY HAZARD IF YOU ARE NOT PAYING ATTENTION. THE TURBOS TAKE TOO LONG TO SEND POWER TO THE WHEELS AND RESULT IS SUDDEN ACCELERATION.

THROTTLE LAG FROM A NEAR (BUT NOT FULL) STOP. IF COMING TO ROLLING STOP, FROM 1-8 MPH, AND THEN HIT ACCELERATOR, THE CAR ENGINE REVS BUT NO ACCELERATION TO VEHICLE. AFTER A 2-3 SECOND DELAY, CAR WILL LUNGE AND ACCELERATE NORMALLY. SCARY WHEN NEED TO ACCELERATE FROM A NEAR ROLLING STOP. LEFT HAND TURNS ESPECIALLY DANGEROUS. EXPLAINED ISSUE TO DEALER, AND Q8 CAR FORUMS HAVE SAME ISSUE. DEALER SAYS FUNCTIONING "NORMAL", WHICH I DISAGREE IT IS NOT. I HAVE TRIED ALL SETTINGS FOR START/STOP, TRANSMISSION SETTINGS, ETC., AND NOTHING FULLY ALLEVIATES THE PROBLEM. THIS IS NOT EPISODIC AND A CONSISTENT, REPRODUCIBLE DANGEROUS ISSUE.

AUTO START/STOP IS TURNING OFF THE ENGINE AND PUTTING THE CAR IN NEUTRAL BEFORE THE VEHICLE IS COMPLETELY STOPPED. IF YOU NEED TO ACCELERATE SUDDENLY TO CLEAR AN INTERSECTION, IT TAKES A FEW SECONDS FOR IT TO START BACK UP AND MOVE THE VEHICLE. LIKE MOST PEOPLE DO, THE THROTTLE GETS PRESSED HARDER IN THE HOPES OF THE VEHICLE MOVING. BY THE TIME THE VEHICLE STARTS BACK UP I'M 3/4 TO THE FLOOR WITH THE THROTTLE WHICH CAUSES THE VEHICLE TO TAKE OFF LIKE A ROCKET. THIS IS OVERLY AGGRESSIVE START STOP IS DANGEROUS. IT SHOULD OPERATE LIKE OTHER SYSTEMS AND NOT SHUT OFF THE ENGINE UNTIL IT IS AT A COMPLETE STOP. I HAVE TAKEN MY CONCERNS TO MY LOCAL DEALER AND THEY TELL ME THAT IT IS OPERATING AS DESIGNED.

THERE IS A SIGNIFICANT LAG IN THE POWER TRAIN OF THE AUDI Q8 AFTER BREAKING TO A COASTING SPEED AND THEN ATTEMPTING TO ACCELERATE AGAIN. THE GAS PEDAL IS COMPLETELY UNRESPONSIVE FOR 2-3 SECONDS DURING THIS TIME. DANGEROUS DELAY IN THROTTLE RESPONSE DUE TO AUTO START/STOP OR MILD-HYBRYD SYSTEMS AND CAUSING VEHICLE TO COAST WHEN SLOWING DOWN AT A YIELD SIGN OR INTERSECTION ETC BEFORE TRANSMISSION RE-ENGAGES. THE VEHICLE IS POWERLESS FOR SEVERAL SECONDS DESPITE APPLICATION OF GAS PEDAL, CAUSING ONCOMING TRAFFIC TO POTENTIAL COLLIDE. ALREADY REPORTED TO AUDI SERVICE BUT THEY SAID IT'S NORMAL, WHICH I TOTALLY DISAGREE

SERIOUS SAFETY ISSUE WITH THROTTLE DELAY FROM DEAD STOP TO GET GOING; DOES NOT HAPPEN ALL THE TIME AND IT IS IMPOSSIBLE TO REPLICATE THE ISSUE; AUDI CLAIMS THEY DO NOT KNOW ANYTHING ABOUT THIS - MULTIPLE PAST COMPLAINTS. I WOULD NOT PURCHASE THIS VEHICLE UNTIL THIS IS RESOLVED. IT WILL KILL SOMEONE. *TR

THE VEHICLES AUTO START/STOP FEATURE PUTS THE DRIVER IN COMPROMISING SITUATIONS WHEN POWER IS DEMANDED FROM THE ACCELERATOR AFTER AN ENGINE POWER-DOWN. THE ENGINE DOES IGNITE TIMELY, (AS SOON AS THE BRAKE PEDAL IS RELEASED) BUT THE DELIVERY OF MOVING POWER IS DELAYED (LAG PERIOD) FOLLOWING AN AUTO "SHUT-OFF AND LEAVES THE VEHICLE IN COMPROMISING SITUATIONS WHERE NO POWER CAN BE DEMANDED FROM THE DRIVETRAIN. WHEN THIS DELAY PERIOD (LAG) HAS PASSED, AND POWER IS FINALLY TRANSFERRED TO THE WHEELS, THE VEHICLE EXPELS THE DEMANDED ENERGY FORCEFULLY, JERKING YOU FORWARD. I FIND THIS TO BE A SAFETY CONCERN PARTICULARLY FOR LEFT HAND (YIELD) TURNS WHERE ACCELERATOR RESPONSIVENESS IS CRITICAL BOTH THE PASSENGERS OF THE VEHICLE AND ONCOMING TRAFFIC. AUDI DEALERSHIP CHECKED OPEN CAMPAIGNS, RECALLS BUT "CANNOT REPLICATE" CUSTOMERS CONCERN. THEY DID HOWEVER, TRAIN ME ON HOW TO "DISENGAGE" THE AUTO START/STOP FEATURE, BUT THIS NEEDS TO BE DONE AT EVERY STARTUP. (IF THERE IS NO PROBLEM, WHY DISENGAGE IT?) AUDI EXPERIENCE CENTER (1-800-822-2834) SAYS THEY RELY ON THE JUDGMENT OF THEIR SERVICE CENTERS AND CANNOT PROVIDE FURTHER GUIDANCE. *TR

AUTO START/STOP FEATURE KILLS ENGINE PRIOR TO VEHICLE BEING COMPLETELY STOPPED RESULTING IN THE DRIVER NOT APPLYING ENOUGH BRAKE "FORCE" TO KEEP THE VEHICLE STATIONARY AFTER THE ENGINE'S RE-IGNITION. WHEN THE ENGINE SUBSEQUENTLY STARTS, THE THE VEHICLE IS JERKED FORWARD AND THE DRIVER NEEDS TO RE-APPLY ADDITIONAL BRAKE FORCE TO THE PEDAL IN ORDER TO KEEP THE VEHICLE STATIONARY. THIS IS A SAFETY CONCERN AS THE DRIVER IS MISLEAD TO HAVE "COMPLETE CONTROL" OF THE VEHICLE WHEN BRINING IT STATIONARY THE FIRST TIME, THEN SUBSEQUENTLY HAVING TO RELY ON "QUICK REFLEXES" TO COUNTERACT VEHICLE BEHAVIOR TO AVOID COLLISION (FROM THE VEHICLE IN FRONT OF YOU, OR FROM INTERSECTING TRAFFIC). AUDIO DEALERSHIP PERFORMED SEARCH OF OPEN CAMPAIGNS & RECALLS. NONE CURRENTLY AVAILABLE FOR THIS MODEL. SERVICE CENTER PAPERWORK INDICATES "COULD NOT REPLICATE CUSTOMERS CONCERN", BUT I WAS PROVIDED EXTENSIVE TRAINING ON HOW TO 'DISENGAGE' THE AUTO START/STOP FEATURE (IF THERE'S NO PROBLEM, WHY DISENGAGE IT?). AUDI CUSTOMER EXPERIENCE (1-800-822-2834) IS UNABLE TO PROVIDE ADDITIONAL GUIDANCE AND RELIES ON THEIR SERVICE CENTERS TO HAVE THE FINAL WORD IN VEHICLE ISSUE RESOLUTION.

AS REPORTED BY OTHERS, IF THE CAR DOES NOT QUITE COME TO A COMPLETE STOP AND ONE ACCELERATES, THERE IS A SEVERAL SECOND DELAY AS THE ENGINE SEEMS TO BOG DOWN. THIS IS RELATED TO THE AUTO STOP/START SYSTEM AS THIS DELAY DOES NOT HAPPEN IF THE AUTO START STOP IS DISABLED.

WHEN TRYING TO ACCELERATE FROM A STOP THE CAR EXHIBITS A 3-4 SECOND DELAY BEFORE ACCELERATING. THIS IS A DANGEROUS CONDITION WHEN TURNING INTO TRAFFIC OR WHEN NEEDING TO QUICKLY ACCELERATE AWAY FROM A HAZARD. IT ALSO CREATES TRAFFIC BACKUPS BY DELAYING LIGHT CHANGES FOR VEHICLE BEHIND. THE VEHICLE AS IT CURRENTLY PERFORMS IS A SAFETY RISK.

TERRIBLE HESITATION AT STOP SIGN LEADING TO CLOSE CALL. CAR WILL NOT START OFF WITHOUT HESITATION OF 2 OR 3 SECONDS LEAVING DRIVER WITH NO CONTROL. THIS IS A VERY DANGEROUS. SEE GOOGLE COMENTS ABOUT 'Q8 PROBLEMS'

VEHICLE WILL HAVE A DELAY (1-3 SECONDS) WHEN PRESSING THE GAS PEDAL WHILE THE CAR IS IDLE, CAUSING A DANGEROUS SITUATION AND LEAVING THE VEHICLE VULNERABLE TO CROSS TRAFFIC, AS IT ROLLS FORWARD INTO TRAFFIC. VEHICLE THEN JOLTS FORWARD AS IT FINALLY ENGAGES. HAS CONTINUOUSLY HAPPENED SINCE PURCHASING THE VEHICLE. WE HAVE REPORTED IT ON MULTIPLE OCCASIONS TO OUR DEALERSHIP, YET THEY BASICALLY SAY THERE IS NOTHING THEY CAN DO OR GIVE US THE RUN AROUND. THEIR SOLUTION WAS TO TURN OFF THE AUTO STOP FEATURE, WHICH SEEMED TO WORK AT FIRST, BUT NOW THE VEHICLE IS EXHIBITING THE SAME PROBLEM, EVEN WITH THE AUTO STOP DISABLED. THINK IT HAS TO DO SOMETHING WITH THEIR NEW MILD-HYBRID SYSTEM. IT IS NOT WORKING THE WAY IT WAS INTENDED. PLEASE LOOK INTO THIS MATTER BEFORE BEFORE A SERIOUS INJURY OCCURS.

THIS VEHICLE AS A SERIOUS INTERMITTENT ISSUE WITH THROTTLE LAG. WHEN PULLING OUT OF PARKING LOTS IF YOU DO NOT COME TO A COMPLETE STOP THE THROTTLE SEEMS TO LAG 1-3 SECONDS. THEN IT SURGES FORWARD WHEN IT FINALLY DOES MOVE. AS OTHERS HAVE SAID IT DOES NOT HAPPEN 100% OF THE TIME WHICH MAKES IT EVEN WORSE. YOU NEVER KNOW IF IT'S GOING TO GO OR WAIT A SECOND OR TWO BEFORE IT MOVES. BEING IN SPORT MODE DOES HELP BUT WHO CAN REMEMBER TO ENGAGE THAT EVERY TIME YOU START THE CAR. I HAVE HAD SEVERAL CLOSE CALLS DUE TO THIS ISSUE. I REFUSE TO LET MY DAUGHTER DRIVE THE CAR BECAUSE OF THIS ISSUE. I'VE DISCUSSED IT WITH THE DEALER BUT THEY HAVE NO FIX OR ACKNOWLEDGMENT OF THE ISSUE.

ON MULTIPLE OCCASIONS, Q8 WILL NOT ACCELERATE WHEN GAS PEDAL APPLIED FOR ROUGHLY 1-3 SECONDS WHEN COASTING TO A STOP OR IMMEDIATELY COMING OUT OF A STOP, CAUSING THE VEHICLE TO REMAIN STATIONARY ALTHOUGH GAS PEDAL IS APPLIED. ONCE THE VEHICLE RESPONDS TO THE DEPRESSED ACCELERATOR, AFTER A DELAY, THEN THE AUTO CAN ACCELERATE BEYOND THE REQUESTED ACCELERATION. IT FEELS LIKE THE VEHICLE IS TRYING TO DECIDE WHETHER OR NOT TO RESPOND TO THE DEPRESSED ACCELERATOR, LEAVING THE VEHICLE VULNERABLE IF TRYING TO CROSS TRAFFIC, ACCELERATE FROM A STOP SIGN, OR TURN LEFT BETWEEN ONCOMING TRAFFIC. THE PROBLEM FEELS INTERMITTENT ALTHOUGH IT FEELS LIKE ITS BECOMING MORE COMMON. VEHICLE RESPONDS THIS WAY WHETHER OR NOT THE AUTO STOP FEATURE IS ENGAGED OR NOT.

THE CAR HAS A SEVERAL SECOND DELAY WHEN PRESSING THE GAS PEDAL IN THE ENGINE IDLE AUTO ON/OFF FEATURE. I HAVE NOT HEARD OF ANY RECALLS OR FIXES TO THIS PROBLEM. DEALER HAS NO FIX FOR PROBLEM.

ON NUMEROUS OCCASIONS VEHICLE ENTERS AN INTERSECTION OR CROSS TRAFFIC WHILE STARTING A TURN AND ACCELERATION LAGS FOR A 1-3 SECONDS. WHEN APPLYING MORE AND MORE GAS PEDAL, IT EVENTUALLY WILL ENGAGE ALMOST CATAPULTING YOU. HAVE COME VERY CLOSE TO GETTING HIT IN THE SIDE OF THE VEHICLE DUE TO THE LACK OF ANY RESPONSE FOR ACCELERATION. CLEARLY THERE IS A MECHANICAL FLAW IN THE WAY THE VEHICLE OPERATES AND IT LEAVES THE DRIVER AND PASSENGER AT GREAT RISK OF INJURY BECAUSE YOU CAN NOT GET OUT OF THE WAY. SEEMS AS IF THE TRANSMISSION IS NOT DOWNSHIFTING TO FIRST GEAR AND BY STAYING IN 3RD GEAR OR MORE, IT CAN NOT RESPOND TO THE ACCELERATION. IT DOES NOT DOWNSHIFT FAST ENOUGH TO ALLEVIATE THE LAG. AFTER RESEARCHING THE PROBLEM ONLINE, THIS APPEARS TO BE A KNOWN PROBLEM BY THE DRIVERS OF THIS VEHICLE BUT NO MANUFACTURER RECOGNITION OF THE SAFETY HAZARD; OBVIOUSLY TRYING TO AVOID LIABILITY. PLEASE INVESTIGATE BEFORE SOMEONE GETS INJURED (IF THEY HAVEN'T ALREADY).

THIS VEHICLE HAS INCONSISTENT ACCELERATION THAT IS DANGEROUS. WHEN ACCELERATING, PARTICULARLY FROM A ROLLING STOP OR SLOW SPEED BELOW 10MPH, THERE WILL BE A DELAY IN ACCELERATION. WHEN THE ENGINE DOES ENGAGE IT TAKES OFF 'LIKE A ROCKET'. IT DOES NOT ALWAYS DO THIS, WHICH MAKES IT SO DANGEROUS. HOWEVER, IT HAS BEEN HAPPENING INCONSISTENTLY FOR 9 MONTHS AND MORE THAN 20,000 MILES AND IT CONTINUES.

SEATBELT APPARATUS AND SEAT DETACHED DURING REAR END MOTOR VEHICLE CRASH.

THERE IS A HUGE (SEVERAL SECONDS) AND DANGEROUS LAG WHEN THE CAR SLOWS DOWN TO THE POINT THE START/STOP SYSTEM KICKS IN (AND STOPS THE ENGINE) AND ACCELERATION IS IMMEDIATELY NEEDED (E.G. THE CARD DOES NOT COME TO A COMPLETE STOP.) IN THAT SITUATION, PRESSING THE ACCELERATOR WILL RESULT IN THE ENGINE STARTING AGAIN IMMEDIATELY (AS IT IS SUPPOSED TO) BUT THE CARD WILL NOT ACCELERATE AT ALL NO EFFECT FOR UP TO 3 SECONDS AND THEN IT WILL SUDDENLY START MOVING TOO FAST WITH A JOLT (DEPENDING ON HOW HARD YOU WERE PRESSING THE ACCELERATOR) THIS SITUATION HAPPENS VERY FREQUENTLY (DAILY FOR ME), INCLUDING IN THE CONTEXT OF LEFT TURNS WHERE CARS ARE COMING IN THE OPPOSITE DIRECTION, MAKING IT A SEVERE SECURITY ISSUE. THIS PROBLEM IS NOT CAUSED BY TURBO LAG. IT IS MOST LIKELY CAUSED BY THE SOFTWARE FAILING TO DOWNSHIFT BECAUSE IT BELIEVES THE CAR IS COASTING. THIS ISSUE IS NOT ISOLATED AND HAS BEEN REPORTED BY PLENTY OF OTHER AUDI Q8 USERS. THERE IS A LONG THREAD ONLINE DISCUSSING IT: HTTPS://WWW.AUDIWORLD.COM/FORUMS/AUDI-Q8-227/INTRO-AUTO-START-MAJOR-THROTTLE-LAG-ISSUE-2966888/PAGE2/

THERE IS A SIGNIFICANT LAG IN THE POWER TRAIN OF THE Q8 AFTER BREAKING TO A COASTING SPEED AND THEN ATTEMPTING TO ACCELERATE AGAIN. THE GAS PEDAL IS COMPLETELY UNRESPONSIVE FOR 3-4 SECONDS DURING THIS TIME. THIS POSES A MAJOR SAFETY HAZARD IN SITUATIONS WHERE YOU ARE COASTING WITH THE EXPECTATION TO CROSS ONCOMING TRAFFIC. I HAVE EXPERIENCED THE ISSUE IN COMFORT MODE. SIMPLY APPLY THE BREAK IN ORDER TO SLOW THE VEHICLE DOWN WITHOUT COMPLETELY STOPPING. WHEN YOU ATTEMPT TO ACCELERATE, THE GAS PEDAL DOES NOTHING. AFTER THE LAG PERIOD, THE VEHICLE BEGINS TO ACCELERATE. I HAVE NOT BEEN ABLE TO REPRODUCE THIS PROBLEM IF I COME TO A COMPLETE STOP AND THEN PROCEED. I RAISED THIS AS A CONCERN TO MY LOCAL AUDI DEALER BUT WAS ADVISED THAT THERE ARE NO SERVICE BULLETINS REGARDING THIS PROBLEM. MY SOFTWARE WAS UPDATED TO THE LATEST VERSION DURING A RECENT SERVICE APPOINTMENT, HOWEVER, THE PROBLEM PERSISTS.

DANGEROUS LAG/PAUSE IN THROTTLE RESPONSE WHEN ACCELERATION IS NEEDED. WHEN COMING TO A ROLLING OR ALMOST COMPLETE STOP, THE AUTO START/STOP SYSTEM IS ENABLED. IF I GO TO TURN/ACCELERATE THERE CAN BE SEVERAL SECONDS OF TIME LAG BETWEEN PRESSING ON THE ACCELERATOR AND ANY THROTTLE RESPONSE. IT IS DANGEROUS AT TIMES WHEN PULLING ONTO A STREET AND THE CAR WILL NOT RESPOND AFTER A FEW SECONDS. ADDITIONAL THROTTLE PRESSURE DOES NOT INDUCE A THROTTLE RESPONSE, AND SUDDENLY THE CAR WILL SURGE AHEAD. THIS IS NOT AN ISOLATED INCIDENT AND AND SEEMS RELATED TO TRANSMISSION PROGRAMMING WHEN THE AUTO STOP/START SYSTEM IS ENGAGED, WHICH IT IS BY DEFAULT. THE DEALER SAYS THE CAR IS WORKING AS DESIGNED. THIS IS DANGEROUS WHEN MAKING CROSS-TRAFFIC LEFT TURNS BECAUSE OF THE UNPREDICTABLE DELAY. THE DATE NOTED BELOW IS JUST TODAY'S DATE, SINCE THIS SITUATION MAY (AND DOES) OCCUR)ANYTIME UNDER THE SPECIFIED CIRCUMSTANCES/CONDITIONS.

THERE IS A NOTICEABLE THROTTLE LAG (HESITATION) WHEN THE AUTO START/STOP FEATURE IS ENABLED, AND THE CAR COMES OUT OF A ROLLING STOP (EX. WHEN MAKING A LEFT TURN). DISABLING THE AUTO START/STOP FEATURE OR SELECTING SPORT MODE NEGATES THE ISSUE.

THERE CAN BE A PROFOUND LAG IN ACCELERATION AT CRITICAL TIMES. I CAN COME TO AN INTERSECTION AND SLOW. WHEN THE GAP IS SAFE TO TURN WITH TRAFFIC OR ACROSS TRAFFIC THE CAR WILL NOT PICK UP AND GO. IT WILL LAG AND NOT ACCELERATE. I WILL COAST INTO THE INTERSECTION AND I FEEL AS IF I COULD BE BROADSIDED. THE LAG IS ABOUT 3-4 SECONDS. NOTHING....JUST A DEAD ROLL. IT WILL PICK UP AND ACCELERATE AT 3-4 SECONDS. I FEEL THAT THE GAP I WAITED FOR WAS TYPICALLY SAFE FOR OTHER VEHICLES I HAVE DRIVEN. IT IS NOT TURBO LAG....I OWN PLENTY OF DIESELS. IT IS DANGEROUS. IT CAN'T BE PREDICTED. IT CANNOT BE PREDICTED. THIS NEEDS TO BE INVESTIGATED BY YOU. AUDI SAYS THAT THE PROBLEM DOES NOT EXIST. THEY ARE UNABLE TO REPLICATE. THEY STATE THE VEHICLE OPERATES AS DESIGNED. BUT IT KEEPS HAPPENING AND CANNOT BE PREDICTED.

MY GORGEOUS NEW AUDI Q8 HAS A DANGEROUS HESITATION ISSUE WHEN ACCELERATION FROM A FULL START WITH AUTO START/STOP ENABLED. THE ISSUE IS DESCRIBED THOROUGHLY IN THE ARTICLE @ HTTPS://TECHCRUNCH.COM/2019/06/10/REVIEW-THE-STUNNING-2019-AUDI-Q8-HAS-A-DEAL-BREAKING-FLAW/. ACCELERATOR RESPONSE IS VERY INCONSISTENT SUCH THAT YOU CAN'T COUNT ON THE CAR ACCELERATING IN A CONSISTENT MANNER. IT EITHER HESITATES OR SURGES FORWARD. TURNING AUTO START/STOP DOES IMPROVE PERFORMANCE, BUT ONE MUST REMEMBER TO TURN IT OFF EVERY TIME YOU START THE VEHICLE. I GOT MY Q8 2 MONTHS AGO. I TRIED TO LEARN HOW TO PREDICT ACCELERATION FROM A STANDSTILL, BUT GAVE UP AFTER ALMOST GETTING INTO AN ACCIDENT WHILE CHANGING LANES AROUND A CAR AT A RED LIGHT. I TOOK IT TO THE DEALER WHO SAYS AUDI HAS NOT ISSUED ANY SERVICE BULLETINS TO RESOLVE THIS ISSUE AND THE PROBLEM WAS NOT HAPPENING AT THE TIME OF THIS TEST DRIVE.

START/STOP SYSTEM HAS NEARLY CAUSED TWO MAJOR ACCIDENTS FOR ME. TURNING LEFT AT AN INTERSECTION WITH APPROACHING TRAFFIC AND PLENTY OF TIME UNDER NORMAL CIRCUMSTANCES TO PROCEED......PUSH ACCELERATOR AND 2 TO 3 SECOND HESITATION (TURBO LAG). CAR DOES NOT MOVE. THERE IS NO WAY TO PERMANENTLY DISABLE THIS DEFECTIVE SYSTEM IN THE AUDI Q8.

EXCESSIVE AND DANGEROUS DELAY IN THROTTLE RESPONSE DUE TO AUTO START/STOP SYSTEM CAUSING VEHICLE TO COAST WHEN SLOWING DOWN AT A YIELD SIGN OR INTERSECTION ETC BEFORE TRANSMISSION RE-ENGAGES. THE VEHICLE IS POWERLESS FOR SEVERAL SECONDS DESPITE APPLICATION OF GAS PEDAL, CAUSING ONCOMING TRAFFIC TO POTENTIAL COLLIDE WITH "STALLED" Q8. THIS IS A MAJOR DESIGN DEFECT IN THE AUTO START/STOP SYSTEM AND OCCURS EVERY TIME THE SYSTEM IS ACTIVE.

THE AUTO STOP/START SYSTEM ON THE AUDI Q8 PRESENTS A DANGEROUS SITUATION WHEN A DRIVER ATTEMPTS TO ACCELERATE FROM A COMPLETE STOP. FREQUENTLY, WHEN I DO THIS (WITH THE AUTO STOP/START ENGAGED - IT'S DEFAULT SETTING) THE CAR WILL NOT MOVE FOR APPROXIMATELY 2-4 SECONDS. WHEN IT DOES ENGAGE, IT FINALLY DOES SO WITH EXCESSIVE FORCE. THIS IS PARTICULARLY DANGEROUS WHEN TAKING A LEFT HAND TURN EITHER ACROSS A LANE OF TRAFFIC OR TAKING A LEFT TURN ONTO A ROAD. FOR THE DRIVER, IT'S VERY DISCONCERTING AS (1) YOU DON'T GET THE POWER WHEN YOU WANT OR NEED IT AND (2) WHEN THE POWER FINALLY DOES COME, IT'S EXCESSIVE AND IF YOU MAY NEED TO SLAM THE BRAKES ON TO AVOID TRAFFIC THAT YOU WERE NOT EXPECTING TO BE CLOSE WHEN YOU FIRST BEGAN THE TURN. THIS HAPPENS REPEATEDLY. IF THE AUTO STOP/START SYSTEM IS DISENGAGED, THEN THIS BEHAVIOR GOES AWAY AND THE CAR OPERATES AS EXPECTED. HOWEVER IT RELIES ON THE DRIVER TO REMEMBER TO DISABLE THE "FEATURE" EACH AND EVERY TIME. FOR SOMEONE LIKE MY WIFE, WHO WILL USE THE CAR A FEW TIMES EACH YEAR (WHEN HER CAR IS UNAVAILABLE), SHE MAY NOT BE AWARE (OR I MAY FORGET TO TELL HER) HOW TO ADJUST THE CAR. SAME WITH ANYONE ELSE WHO MIGHT DRIVE THE CAR.

THE AUTOMATIC LANE CENTERING (ALC) AND LANE KEEPING ASSIST (LKA) ARE UNRELIABLE. THE ALC INFREQUENTLY CAUSES THE CAR TO SWERVE OFF THE ROAD AND BOTH FUNCTIONS DO NOT WARN WHEN NECESSARY AND INEXPLICABLY FAIL TO RECOGNIZE THE LANE MARKINGS.
