“While driving my Audi A6 avant quattro, smoke began coming out of the drivers side dash vent. I stopped the car as soon as I safely could and called 911, as soon as I was out of the vehicle the smoke became worse and flames began rolling out of the dash area. The fire was extinguished almost immediately with a fire extinguisher which a nearby resident luckily had handy. By viewing this fire at close range I am certain that the vehicle would have been completely engulfed within minutes. …”
NHTSA complaint #10283285, filed 2009-09, 181,000 miles“I own a 1999 Audi a-6 sedan. Today it had a fire in the dashboard near the driver's side. Fortunately it occurred while it was at home where I had access to fir extinguishers and tools to disconnect the battery. It took 3 extinguishers to put out the blaze. Just moments earlier, my wife and 5 year old son returned home from church complaining of a toxic smell in the car! We were very fortunate the situation was not worse!”
NHTSA complaint #10048913, filed 2003-11, 44,000 miles“My 1999 Audi A6 avant ignition switch failed causing the lack of turn signals, windshield wipers, heater and horn. The bernardsville Audi dealers claims it fried some wires which to me sounds like a safety and fire hazard.”
NHTSA complaint #10146949, filed 2006-01, 127,600 miles“While driving my 1999 Audi A6 on the expressway with my 3 year old son in his booster seat, the driver side of the dashboard starts to smoke . Then in less than a minute flames were coming out, by the time I was able to pull over, my dashboard was completely on fire,while taking my son out the airbag blew, scaring him even more, and not to mention all the toxic fumes we inhaled. The insurance tells me the car is a total loss, and if that airbag was activated while I was still driving, it could have been fatal.”
NHTSA complaint #10158175, filed 2006-05, 92,000 miles“I was pouring windshield fluid into my Audi A6 one day. I sat down in the car to move it onto the street because I wanted to wash it, I turned the ignition on, as I got in I smelled burning plastic. I thought nothing of it so I drove it to the street. Smoke started pouring out of the vents on the drivers side of the cabin. I rolled down the windows and the sunroof because I thought the air-conditioning or heater was having a problem. I turned the car off and got out and watched the smoke for a minute. The smoke then turned a black-dark grey color. …”
