NHTSA Complaint #11711678 — 2015 AUDI A6

I am writing to report a serious and life-threatening safety incident involving my Audi vehicle following recent service performed by an authorized Audi dealer. Vehicle information: Model: Audi (2015) VIN: [XXX] Servicing Dealer: Audi Lafayette IN Date of Service: 2026-01-14 A few days after the service appointment, my wife was driving the vehicle from Lafayette, Indiana to Chicago on the highway at normal speed when the vehicle suddenly became unstable and difficult to control. The car experienced violent shaking and loss of directional control, creating an immediate risk of a high-speed accident. Fortunately, she was able to safely bring the vehicle to a stop on the highway shoulder. The vehicle was then towed back to the same dealership. Preliminary inspection strongly suggests a wheel / tire installation failure, which occurred less than a week after dealer service. This incident placed my wife’s life — and the lives of other motorists — in serious danger. We are extremely concerned that this failure may be the result of improper installation or torque procedures performed during the dealer service. At this time: We have not authorized any repairs or alterations to the vehicle We are preserving the vehicle condition for documentation and investigation We are requesting Audi of America’s immediate involvement Given the severity of this incident, we respectfully request: A formal Audi of America safety investigation Preservation and review of all dealer service records and technician documentation. This was not a minor inconvenience — this was a near-fatal highway safety failure, and we believe it requires urgent attention at the corporate level.
