2021 Audi Q7 Electrical System

I am filing this complaint regarding a serious safety and mechanical issue involving my 2021 Audi Q7. The alternator on my vehicle was replaced by Audi in November 2024 as part of an official Audi recall. On October 22, 2025, less than one year later, the alternator failed while I was driving, causing the following safety hazards and damages: Sudden loss of battery power Complete battery drain Damage to the electrical stabilizer Vehicle shut down while driving Required towing Left me stranded on the road Another independent auto shop confirmed that the alternator failure directly caused the battery to fail. My vehicle is only four years old, and the battery should not fail under normal operation unless another component (such as the alternator) is defective. Audi of America refuses to cover the resulting damages, even though the alternator was replaced under their recall and failed prematurely. They have denied reimbursement for repairs, towing, and related expenses, despite clear evidence that the alternator caused the battery and electrical damage. This is a serious safety concern because the alternator failed without warning, and the vehicle lost electrical power while driving. I am requesting NHTSA to review this issue, as the failure of the recall-installed alternator may impact other Audi Q7 owners and may indicate a broader defect or improper recall repair. Thank you for your attention to this matter

The contact owns a 2021 Audi Q7. The contact received notification of NHTSA Campaign Number: 25V201000 (Electrical System). The interface turned off, and the touchscreen was inoperable. The CP message was displayed on the instrument cluster. The vehicle was taken to the local dealer, who confirmed that the USB port was not working and was not covered under warranty. The vehicle was not repaired. The contact reached out to another local dealer, Audi Riverside (3210 Adams St, Riverside, CA 92504), but no additional assistance was provided. The manufacturer was contacted and offered a discount on the repair, but no additional assistance was provided. The failure mileage was approximately 98,000.

Twice in the last 2weeks the vehicle has an electrical system failure while on expressway. This is dangerous as the message tells you to immediately stop driving. On a highway this is a serious hazard.

So models which have digital cockpits that were produced before July 2021 are faulty and the screen goes black. I was on the I95 when the display was gone and I didn’t have a speedometer. The manufacturer is already aware and accepts there’s a issue but doesn’t have a recall.

Car displayed electrical Issue when driving daughter to school. Let husband know but was only a yellow warning and had a full day planned. I unfortunately assumed it was just a battery issue and continued with my day, but made an appointment at Audi for repair. I drove to my next appointment and the yellow warning moved to a red warning but I was 20 minutes from home. I called my husband and warned him I’d probably not make it all the way home, I made it another 10 miles and then it completely turned off on the freeway, I was prepared and had stayed in the right lane thinking this could be coming. Towed the car to Audi, they are ordering parts and warned it could be 4 weeks before I got my car back. The “generator” needs to be replaced.

Starter Generator Failed on 10/12/2023 while the car was being driven. Warning received was "Electrical system: Malfunction! Safely stop vehicle" There are multiple reports online of people experiencing similar problems and have had recalls. We never had a recall and this could have caused a fatality. We feel Audi has been negligent.

While driving, vehicle flashed red error codes for an electrical system malfunction and indicated that the vehicle should be stopped as soon as possible. As part of this failure, the auto start/stop for the vehicle became disabled. Vehicle was towed to Audi dealer, and after sitting on the lot for a week, the dealer confirmed that the starter generator for the 48V mild hybrid system failed.

One while the wife was driving approximately 20 MPH the vehicle suddenly shut off in the middle of the road. The vehicle was later towed to the local dealer who diagnosed that the alternator was faulty and needed to be replaced. The vehicle was not yet repaired. The contact was informed by the service advisor that the failed alternator was a known issue and the manufacturer had extended the warranty for the alternator and the replacement alternator was on a ten-week delay due to the high demand for the part. The manufacturer was notified of the failure. The failure mileage was 27,000.

My 2021 is having an issue with the starter generator. Apparently this is a issue with many Audi's

At approximately 3:15pm CST on Friday, January 13, 2023, several electrical system warnings appeared, and the vehicle stopped in the middle of the street. We were able to restart the vehicle twice, but only able to drive it about 10 feet to move it out of the middle of the street. We then had the vehicle towed to the dealership for repairs. The dealer has told us that the electrical generator failed and needs to be replaced. It should be available for inspection, if needed. No other party, such as police or insurance, has inspected the vehicle. My safety and the safety of others was put at risk, because the vehicle died in the middle of the street with little warning and could only be moved a short distance from there. Pictures of some of the warnings are attached.

Upper dashboard display (MMI) loses power, upon reboot, audio volume comes on full power momentarily. This loud noise is both startling and distracting to the driver. The failure is sporadic and Audi has been unsuccessful in resolving the issue.
