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..

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.

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

Feb 01, 2022

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.

SERVICE BRAKES

2 complaints

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.

Dec 21, 2017

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.

SUSPENSION,ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE

1 complaint

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

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.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,SERVICE BRAKES

1 complaint

I WAS DRIVING ON A SUBURBAN CITY STREET IN A STRAIGHT LINE WITH NO CARS OR ANY OTHER OBSTRUCTIONS AHEAD OF ME OR BEHIND ME. WITHOUT WARNING, THE CAR ENGAGED ITS EMERGENCY BRAKING THROWING MY DAUGHTER AND ME FORWARD VIOLENTLY INTO OUR SEAT BELTS. WHEN I FELL BACK, THE DASHBOARD WAS SHOWING ME A PROXIMITY WARNING BUT AGAIN NOTHING WAS ANYWHERE NEAR OUR CAR. THE SERVICING DEALER SAID THEY DIDN'T FIND ANY ERROR CODES AND SO THERE WAS NOTHING THEY COULD DO. THIS HASN'T HAPPENED AGAIN (YET) BUT THE CAMERAS ALL AROUND THE CAR THAT ENGAGE FOR PARKING AND IN REVERSE ARE CONSTANTLY GOING OUT AND/OR THE VEHICLE MMI SYSTEM RANDOMLY RETRACTS INTO THE DASH WHILE DRIVING.

STEERING,WHEELS,SEATS

1 complaint

CAR VIBRATES AT ALMOST ANY SPEED OTHER THAN IDLE. I HAVE HAD THE CAR BACK TO THE DEALER SEVERAL TIMES. THE VIBRATION CAN BE FELT THROUGH THE STEERING WHEEL, THE SEATS AND ON THE DASHBOARD. I CAN'T GET THE CAR FIXED. I HAVE ASKED AUDI TO REPLACE THE CAR IF THEY CAN'T FIX IT. NO RESPONSE. I HAD 5 AUDI A8'S IN THE PAST AND NEVER EXPERIENCED ANY SUCH PROBLEM I AM ALMOST AFRAID TO DRIVE THE CAR. I LEASED THE CAR FOR 15,000 MILES PER YEAR AND ONLY HAVE 7800 MILES IN 11 MONTHS BECAUSE OF THIS FEAR.

VEHICLE SPEED CONTROL,SERVICE BRAKES,FUEL/PROPULSION SYSTEM

1 complaint

THE BRAKE AND GAS PEDALS ARE TOO CLOSE. I CONSISTENTLY HIT THE BRAKE WHILE ACCELERATING. THEY NEED TO BE SPACED FARTHER APART, AND THE BRAKE PEDAL MOVED TO THE LEFT. THERE ARE COMMENTS ALL OVER THE INTERNET ABOUT THIS PROBLEM AND AUDI SERVICE SAYS THERE IS NO FIX. I HAVE LARGE FEET AND HAVE NEVER HAD THIS PROBLEM WITH ANY OTHER CAR MANUFACTURER. I NEED THE NHTSA TO GET INVOLVED BEFORE SOMEONE GETS HURT. THIS IS A VERY BIG DEFECT THAT NEEDS TO BE FIXED.

WHEELS HAVE BEEN REPLACED WITH THOSE OF ANOTHER CAR AND TIRES HAVE BEEN REPLACED BUT TO NO AVAIL.
