Engine & cooling

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..

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.

Engine & cooling

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.

Engine & cooling

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...

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.

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 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.

Brakes

On three separate occasions, the vehicle did not stop when the brake pedal was pushed at highway driving speeds. This does not happen all the time. Car has been towed to audi dealership twice, yet they find nothing wrong with the vehicle because the diagnostic tests that they are running rely on the computer, which is defective to begin with and not recording the necessary failure (codes) for when the brakes fail on the vehicle. We have no choice but to continue driving the per audi dealership (open road / audi manhattan) until lease end.

Brakes

When braking the car vibrates, sometimes so violently that it is unsafe to keep applying the brakes to control the speed of the vehicle. Currently the vehicle has been in service since june 27, 2015 and has been driven 21,000 miles. However, this vibration has been noticed early in the life of the car. Originally, I thought the vibration was due to the road surface or condition, but I have come to realize that this problem is a vehicle fault. In the most recent incident we were driving from payson, arizona to...

mesa, arizona using the vehicle cruise control. On this road, us 87, there are a few inclines of about 6% that run for 2 to 3 miles. As the car gained speed going down the incline the cruise control would apply the brakes and extreme shuddering and vibration of the vehicle occurred. To maintain a safe speed we eventually reverted to engine braking to control a safe speed. This highway is very well maintained and I am certain that the road conditions did not contribute the the violent shuddering of the vehicle. My wife and I have been retired for several years and we have not driven this vehicle hard or had any emergency stops. The vibration is present, to a lesser degree, at slower speeds and varies considerably day to day. I have owned two lexus' prior to the a8l. Both the ls400 and ls430 were driven 120,000+ miles without a brake problem or vibration during braking. The pads may have been replaced once, but the rotors never had a problem.
