Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The ABS control unit on my Audi A4 failed after 95,000 miles. I have no anti-lock braking and Audi has denied any responsibility for the part since it is out of warranty. Searching through Audi forums I found this failure to be very common and everyone had no ABS until the control unit was replaced which cost an average of $1500+. There were no events that lead up to the failure, I started the car one day and the ABS and brake light started flashing on my dash. I tested the ABS and found that it indeed does not prevent my brakes from locking up. …”
