  1. Look up the VIN for open recalls at nhtsa.gov. This year has 4 campaigns on file below.
  2. Airbags. Confirm the airbag light behaves normally and that open airbag recalls are closed.
  3. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  4. Lights. Walk around the vehicle: headlights, brake lights and turn signals all working.
  5. Skim a few owner reports below for Airbags. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

The contact owns a 2008 Audi A4. The contact received an unknown recall notice related to the air bags. The contact scheduled an appointment at a dealer and had the recall serviced. The contact then stated that while idle in the parking lot of a hospital, a speeding vehicle clipped the front end, driver's side of her vehicle, which caused the entire front bumper to detach from the vehicle. The driver also hit a gate, guardrail, and utility box in the parking lot. The air bags did not deploy upon impact. The contact was then treated at the hospital for an injury to her neck and left shoulder. The contact sustains severe headaches weeks after the accident. The contact received an X-ray and had been assigned to physical therapy for the next few months. The other driver was not injured as a result of the accident. A police report was filed. The vehicle was initially towed to an independent mechanic and was later towed to a storage unit. The contact family member, who is mechanically inclined, stated that the vehicle's air bag sensors were defective. The vehicle had yet to be diagnosed or repaired by dealer. The dealer was notified of the failure and referred the contact to the manufacturer; the manufacturer gave the contact a case number. The failure mileage was approximately 140,000.

Audi is wanting me and another driver to drive 2.5 hours to their dealer drop off the car for repairs, then drive back. Then after the repairs are complete make that trip again. They want us to spend 20 man hours driving, plus gas, food, and mileage. None of this is reimbursed. I have called and written Audi several times with the same answer. This is unreasonable when they have a local VW dealer and other Audi certified mechanics that can do the job within 20 minutes. Our zip code is [XXX] .

While I was driving on the highway the sunroof (just the window) flew off. I had the sliding roof door closed and only heard a gust of wind initially thinking it just became ajar somehow, but nope the entire window was gone, like the adhesive deteriorated I assume. The sunroof mechanism works perfectly fine. Fortunately if was really early in the morning and to my knowledge no one was on the road, but if they had been an injury or death could have happened!
