Chronological view of owner reports
While driving at normal speed, the entire digital instrument panel suddenly went black and a red warning triangle appeared. I lost all gauges, including speedometer, fuel level, and warning indicators. This created a serious safety risk because I was in active traffic and had no way to know my speed or see alerts. My VIN shows an open recall for this exact defect (instrument cluster blackout), but the failure has already happened during normal driving. I consider the vehicle unsafe to drive until repaired.
Vehicle had electrical system malfunction. Vehicle provided an electrical system malfunction and vehicle starting system malfunction warning message a few days prior to the incident. Vehicle has approximately 20.5K miles on odometer. Before I was able to bring it to service, the electrical system malfunction message became more severe and turned from yellow to red. While driving, the vehicle progressively shut down ABS, lane departure, and other systems and gave a transmission warning message. Eventually, the car lost power and I was left stranded at the side of the road.
The contact's wife owns a 2021 Audi A6. The contact received notification of NHTSA Campaign Number: 22V155000 (Electrical System) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was contacted and was unable to confirm when parts would become available. The contact had not experienced a failure. VIN tool confirms parts not available.
The contact owns a 2021 Audi A6. The contact stated while his father was driving 45 MPH, the electrical system Malfunction warning light illuminated. The contact stated that several electronic components started to turn off until the vehicle stalled. The vehicle was not drivable. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the starter generator to be replaced. The vehicle was not repaired due to the parts being on backorder. The manufacturer had been informed of the failure. The failure mileage was approximately 38,000.
Multiple warnings indicating to contact dealer (Lane departure, adaptive cruise control, collision avoidance, electrical system, start/stop, etc) then 1 minute later transmission failure and engine failure imminent. After a minute or two my center MMI went blank then my electronic dash went blank, transmission went into neutral and the engine died all within a few seconds. Fortunately I was able to coast to a stop in the center median of an expressway and contacted the dealer. Flatbed towed to dealer who stated most likely the generator between the lithium battery bank and gas engine failed. They have seen several in this year for A6 and A7's with mild hybrid engines. I was lucky to be in low volume traffic as there was no power to indicate to drivers around me that my engine quit and not even turn signals worked. After having car towed to Audi dealer, they proceeded to tell me it was the starter/generator and the part was on back order for two to three months.
Liquid spulked in the trunk and somehow was able to get to the control module that is located under the rear seat similar concerns as recalled Audi Q5. Vehicle malfunctioned in the middle of a busy intersection.
