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.
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.
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 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 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.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
