A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

The negligent driver yielded to the flow of traffic without stopping. When he collided with us, the airbags (exploded) deployed so strongly that they damaged the windshield and our bodies: face, neck, etc. Our beloved Audi A4 2009 was totaled and after that we had several operations: 2 eye operations (need 2 more), dental surgeries, 3 neck surgeries ... multiple unpaid medical expenses.

November 2019 CrashInjury

I had an accident in my audi a4 convertible and the driver airbag did not deploy. Due to sun glare, I rear-ended a mercury mountaineer with my 2006 audi a4 convertible. I never saw his taillights, I was not messing with the radio or talking on the cell phone. I was not cited, although the accident was clearly my fault. I was the only one in the car. I was wearing my seatbelt and shoulder harness in the correct fashion. My injuries were minor bruising and a rub mark on my neck from the shoulder harness.

This car has been a nightmare .. After basically having the engine rebuilt due to an oil consumption lawsuit that had been an ongoing problem since 19,000 miles and just been bandaided up with excuses from the dealership, but now the vibrations are blamed on the motor mounts. Will the crap just ever end? Or will I fix the mounts and we can point the finger at something else. It just seems like there is no end..
