Had car towed to dealer for recall was there 4 months was told they didn't want to work on in now they have had it towed off there lot with out telling me
So I purchased a vehicle from wright drive in El Paso, Texas. I was driving home back to Alamogordo which is 90 miles away, maybe 80 I realized there was no adaptive cruise control. So I messaged dealership. They told me that there was nothing they could do. It's not a safety issue. I got the vehicle home the next day. I found out the whole front suspension was bad. I kept hearing a noise when I would drive over bumps and it was really loud. I contacted the dealership, told them that the suspension was bad. They...

told me to take it to Audi to have them look at it. It came out to like $8,000 worth of repairs. They told me they would not pay that and I could return the vehicle for a full refund. I told them okay. I would be there in 3 days because I was working. They said that was fine. I get there 3 days later they told me that was no longer an option. So I got stuck with the car that needed $8,000 worth of repairs and then another four for more suspension parts. New breaks the 3,000 to fix the adaptive cruise control. I understand the adaptive cruise control is not really a big deal but the fact that they lied about me being able to return the vehicle and now I'm stuck with the vehicle thing that I've paid more fixing a suspension then the car is even worth. I'm a single father with two kids. I cannot afford to keep paying for a car that they should have taken back to begin with because it's illegal to sell a vehicle that has saved the issues
Yet another beautiful Audi 3.0tfsi with the rocker arm failure ... how is there not a class action lawsuit already ? I have a knock in my valve train and I just bought this car two days ago .... Audi should be liable to fix this because I didn't know nothing about this and with a quick search it's alike a epidemic of the same problem..
Water leaking from passenger side top right corner from windshield. Glass isn't damaged. Just started leaking for no reason
Leaking windshield on passenger side top left corner
The contact owns a 2015 Audi A8. The contact stated that while driving approximately 55 MPH, the check engine warning light illuminated and the vehicle that stalled. The vehicle was towed to the dealer. The dealer diagnosed the vehicle and stated that the engine failed and needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 110,000.
With out any prior warning the car began to sputter and then lost power while I was on the highway. I had the vehicle towed to the dealership and found the Turbos failed which caused the problem. This car has been well maintained and serviced by the dealership. It now has a $14000.00 repair bill.
Turbo chargers failed on highway at highway speeds leading major loss of power in a passing situation nearly causing an accident then the car stalled at exit ramp
Engine stalled as i approached departure terminal at Newark airport. Dealer has inspected and determined the Turbo Impeller is bent and requires replacement. Car will not run. This is a known problem on Audi turbo engines apparently. Just prior to stalling the oil low light came on then the car stalled out creating a hazardous safety situation for a perfectly well maintained car.
The stock turbo when right in the middle of traffic at 60,000 miles. Almost died in traffic as the car would not move out of the road. This is not exclusive to A8 but to all the audi cars with the 4.0T engine across many vehicle years. An OEM turbo should last 150k-200k miles (half that if aftermarket). Cost $10k to replace.
Car stalled in left turn lane. Restarted with difficulty, and loss of power. No warning lights. Diagnosed by dealer to be failed twin turbochargers. 45688 miles. Replaced under extended warranty. Dangerous as car stalled in an intersection with no prior warning.
My car's engine started stuttering and idling very roughly while exiting the expressway. The ec and check engine lights came on. It continued to shutter, and shake, until it shut off. It wouldn't restart, and I had to have it towed to the dealership where I purchased it. The dealer confirmed the issue, and reported the turbos had excessive play and scoring on the surface of the housing, caused by the excessive play in the turbos. Turbochargers needed to be replaced.
Regular driving east bound on i-80 and after going up a hill my car couldn't go over 3500 rpms. Thought it was the ecu putting it into limp mode because of weather conditions. Turned out both my turbos blew at 67,000 miles and lead to total engine failure with metal shavings reaching the exhaust and loitering the oil pan.
After getting off the highway, the engine just quit. Fortunately we were at a stop sign at the end of the off-ramp. There was no warning and we were not able to restart the car to move it out of traffic nor could we shift into neutral. Had this happened a few minutes earlier, we would have been traveling at 70 mph. Fortunately, my son was driving, because at my age had this happened at highway speed, there is no way I could have steered it to safety without power steering. I know that this is not the first incident...

of this happening to this model car. It should be a safety recall before someone gets killed because of this problem. It's a shame that audi is forcing its customers to cover the cost of this safety issue.
Engine shut down at highway speed ~65mph while decelerating into toll booth our to turbo failure. Complete engine shut down. Lost power in highway traffic. Dangerously navigated through ezpass lane without power. Hazards on. Dangerously navigated to shoulder, coasting, with no engine power. Came to complete stop on shoulder. Was able to restart motor and drove directly to audi dealership. Dealership confirmed known turbo failure problem on vehicle model. This is a potentially deadly condition and needs to be...

federally addressed. Audi has a 2015 supplement to emissions warranty identifying the turbo failures and there is a federal statue to extent this correction to 7yr 70k miles. Regardless, it should be a safety recall.
Turbo failure at 57,000 miles. Car died while in traffic while going down the road.
The driver seat badges a back and forth a little bit and the transmission shifts roughly in dynamic mode and there is a big vibration when car is shifting gears
Front collision warning system light does not illuminate in the heads up display and the audio portion of the alarm is not audible. I have taken this to the dealer and they have no resolution. The blind side warning system has no audio.
BAD WATER PUMP AND CROSS BAR
Car ran rough on the way home from picking up take out dinner - metallic, rapid popping sound coming from engine bay (faint with window up). Car died while slowing at a stop light and would not turn on - steering wheel also locked, power brakes failed. I was able to bring my car to a stop before striking a boulder using non-power brakes. Car was towed to nearest audi dealership and I was informed that both (!) Turbos failed at just over 70,000 miles and meticulous service. Oil was changed at half the recommended...

interval (@5,000 miles). Expensive repair that shouldn't be happening at such low mileage (and extremely frequently from owner reports) that also led to a completely loss of control and some brake function. Audi has a tsb on the issue, but wondering why the dot/nhtsa has yet to enforce a recall? *Tr
I was involved in a rear end collision and my air bag didn't deploy causing me a head injury. My vehicle was stationary siting in highway traffic. My vehicle sustained $16,000.00 In repair cost.
I was driving down the highway then my engine shutoff, it was very hard to control the car, I was able to pull over. Audi says both turbo had blown, I guess its common.
I have owned my 2015 audi 8l for 6 months and it has started to stall whenever I start the initiation button. Often times it will just shift off causing me to have to restart it multiple times. I brought this issue up my local audi dealership and they have acted as if they were totally unaware of this issue. Also I keep getting low pressure in my from right tire, this keeps me from being able to drive long distances as I am military stationed in an isolated area. *Tr
The car experienced a oil separator failure. The made an extremely loud whistling sound at idle. This is a known issue and audi issued a tsb for it but did not issue a recall. The car ran very rough. To fis this issue I had to pay over $2,000 to have an new version of the oil separator installed. Audi should issue a recall on this since they know the original part is defective.
Engine stalled in traffic and car would not restart. Car was operating normally, pulled up to a red light to turn left on to busy 2-lane highway. Engine began sputtering and car lurched forward. Light turned green, was able to turn left on to the road. I got 1/3 mile down the road and the engine stalled completely and would not restart on multiple attempts. Car was disabled and stuck in traffic. Car towed to dealer. Dealer diagnosed failed turbochargers. Car had 68,800 miles on it at time of turbocharger...
