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.
2015 Audi A8 engine complaints
Page 2 of 2: complaints 11 to 18 of 18, newest first, as owners wrote them.
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.
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/the federal safety agency has yet to enforce a recall?
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.
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 failure. Car was serviced at audi dealer for every service interval per manufacturer recommended mileage-based intervals. Car/engine has not been modified in any way with aftermarket parts.
