Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving the emergency parking brake engaged itself without warning or cause. This caused the vehicle to come to an abrupt stop. Luckily I was in a parking lot but if I had been in a high traffic area or intersection, it could’ve caused a collision. I had 2 passengers who witnessed this sudden bizarre event. There was nothing that could’ve caused this to happen. It scares me & now I’m worried this could happen again without warning. The sensor screen was beeping with a message to put my car in park before setting the brake. Made no sense why this happened.”
NHTSA complaint #11441169, filed 2021-11“An Audi dealer installed 245/40R18 93H tires on this 2018 Audi A4, while the vehicle placard/specification requires 245/40R18 97H. The lower load index reduces capacity from 1,609 lb per tire to 1,433 lb per tire, approximately 704 lb total across four tires. This creates a safety risk because load-rated tires affect vehicle stability, heat buildup, braking, steering/cornering, suspension loading, and tire failure/blowout risk. …”
NHTSA complaint #11747798, filed 2026-07“New factory brakes make very loud audible screeching sound when coming to a stop.this happens just before coming to a complete stop and sometimes in the beginning of breaking. Mechanic has worked on this issue several times and reordered brakes from local Audi dealership and it is still making the sound. Dealership said its 4th generation brakes and its a problem with the coating.”
