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.
