Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Two issues: the small portable air pump that came with the car would blow the fuse to the 12v cigarette lighter. After a new fuse is put in, this would happen on about every third or fourth time of using of the pump. I have replaced about 5 fuses already. The second issue is the squeaking of the rear brakes when backing up during cold or hot. However, it does happen more when cold/in the morning. A factory dealership had look at the issue but found nothing.”
NHTSA complaint #11384175, filed 2020-12, 15,700 miles“While driving, Forward Collision Warning appears without any reason. My understanding is that the car will brake itself if it senses frontal collosion and I am concerned that it might brake suddenly without my knowledge and cause an accident.”
NHTSA complaint #11560590, filed 2023-12“COMPONENT: 48V mild-hybrid electrical system — engine ground connections, Belt Starter Generator circuit, and 48V lithium battery. The vehicle is available for inspection upon request; the 48V battery dealer now call failed has not yet been replaced. SAFETY RISK: On 8/1/2026, the vehicle suffered sudden, complete electrical failure while in motion immediately after exiting I-75 in Bradenton, FL, with my family aboard, including a child. The cluster displayed “Electrical system: malfunction! Safely stop vehicle” (red), then total power loss. …”
NHTSA complaint #11773489, filed 2026-10“In July 2023, my 2020 Audi Q7 experienced a complete electrical failure at highway speeds due to a Belt Starter Generator (BSG) malfunction. Audi replaced the BSG with the same faulty part. Months later, I noticed increased oil consumption and loud engine noise. Despite multiple service visits and reporting these issues, Audi failed to properly diagnose the problem. In January 2025, despite a clear check engine light indicating a problem, Audi dismissed my concerns. Just weeks later, in February 2025, the engine catastrophically failed due to undiagnosed internal damage. …”
NHTSA complaint #11652576, filed 2025-04“while driving the vehicle, I received a warning that there was an electrical system failure. Then the entire care shut off in the middle of the highway. There was no way to get the vehicle into neutral to push it to a safer location out of traffic. I was in the vehicle with my two children. This left us stranded in the middle of the highway with a significant amount of traffic. There was no way to get the vehicle back on. This seems to be a known issue with Audi and they have notified the dealerships about it but have not issued a recall. Please expedite this as a recall. …”
