NHTSA Complaint #11406821 — 2016 AUDI S7

EXPERIENCED TURBOCHARGER FAILURE WHEN COMING TO A STOP AFTER GETTING OFF THE INTERSTATE AFTER APPROXIMATE 2.5 HOURS OF DRIVING. ENGINE DIED AS CAR SLOWED DOWN SO SUSPECT THE TURBOS FAILED WHILE DRIVING BUT RAM AIR FROM INTERSTATE SPEEDS WAS ADEQUATE TO MAINTAIN THE ENGINE UNTIL IT SLOWED DOWN. THE EXTENDED RUN TIME WITH FAILED TURBOS RESULTED IN METAL FRAGMENTS IN THE OIL SO AFTER INSPECTION, THE ENGINE WAS REPLACED UNDER AN EXTENDED WARRANTY WITH A USED ENGINE. THIS ENGINE HAS APPROXIMATELY 58K MILES ON IT AND I THINK THE REPLACEMENT ENGINE HAD 11K OR SO ON IT. THIS OCCURRED ON DEC 26TH, 2019. THIS PAST FEBRUARY, 2021, NOTED AN ODD WHISTLE SOUND FROM THE TURBO BUT NO WARNING LIGHTS AND SLIGHTLY SLUGGISH ACCELERATION. THE FOLLOWING DAY IT SEEMED TO RUN FINE ON MY WAY TO WORK BUT ON THE WAY BACK IT RAN ROUGH AND THEN DIED SO I HAD TO STEER OFF THE ROAD INTO A PARKING LOT AS I LOST POWER STEERING. FURTHER INVESTIGATION DETERMINED THAT ONE TURBOCHARGER HAD COMPLETELY FAILED (THE TURBINE WHEEL WAS COMPLETELY SHEERED OFF) AND THE OTHER HAD EXCESSIVE PLAY IN THE SHAFT. THE 75K FACTORY MAINTENANCE HAD JUST BEEN PERFORMED IN DECKER, 2020, AS HAD THE 65K MAINTENANCE EARLIER IN THE YEAR. SINCE THE REPLACEMENT ENGINE WAS NO LONGER COVERED UNDER A USED PARTS WARRANTY OR MY EXTENDED WARRANTY, THE COST OF TURBO REPLACEMENT WAS ENTIRELY OUT OF POCKET. I ALSO HAD TO PAY FOR SOME EXTRA WORK ON THE FIRST ENGINE REPLACEMENT DUE TO DISCOVERY OF EXTRA WORK REQUIRED FOR THE SWAP THAT WASN'T IN THE INITIAL QUOTE TO THE EXTENDED WARRANTY COMPANY.
