One problem related to rear suspension coil springs has been reported for the 2010 Audi A4. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2010 Audi A4 based on all problems reported for the 2010 A4.
The coil springs broke on this vehicle on 2 separate occasions. The left front coil spring broke while it was being driven by my husband on 7/24/19. The left rear coil spring broke while I was turning out of my driveway on 4/21/20. The vehicle has over 81,000 miles, but is in very good condition. I am careful to avoid pot holes while driving, so I don't believe the cause is due to my driving habits. The photo I have provided shows the break is not due to rust. This has never happened with any vehicle that I have driven in the 50+ years I have been driving . My understanding is that a broken coil spring is very dangerous and can cause an accident particularly if it punctures a tire while driving. My suspicion is that the coil springs are defective given that the breaks occurred with 2 different coil springs. Since this has happened twice, I chose to replace all the coil springs in the car because I fear for my safety. I understand that volkswagon, of which Audi is a part of, recalled over 56,000 vehicles last year due to defective coil springs. However, I cannot find any information regarding a recall for Audi coil springs.
