What owners report most

Verbatim excerpts from NHTSA complaints, by component

Air bags

51 reports3 crashes
“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.”

Engine

45 reports1 crash1 fire
“The turbo sounds like it's not going in/out of gear, oil going into spark plugs, radiator fluid leaking system getting real hot. Low engine poer picking up speed an issue. Air bag rear brake light malfunction, oil pressure not correct”

Steering

15 reports1 fire
“I bought the car recently and drove it on the freeway, on the way back home I noticed a shaking/Vibration coming from the right side of the vehicle. It made the car very hard to control and staying in one lane was almost impossible. It swerves left to right uncontrollably at random times. I haven't taken it in to any dealership or manufacturer to check it out for me, also there's no warning lights on the dashboard at all. And I believe the owner I bought it from knew of this issue but didn't let me know so I'm really just as in the Blind as well. I don't know what else to do because I can't keep driving the car with uncontrollable force and putting kids in danger or anybody else's.”
