Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“During a recent rain storm I went to start the car to discover 6 inches of water in the back seat. Rear airbag and some electrical system had been fried. When I contacted Audi they said that it was not a warranty issue that it was my fault. That a line under the battery compartment had been clogged by pine needles causing the water to flow into the car through the airconditioning system. It seems to me that this is a design flaw and should be covered by Audi.”
NHTSA complaint #10300425, filed 2010-01, 52,000 miles“My 2005 Audi A6 has water damage. Some how over night heavy rain seepage left an inch of water behind driver seat. Car was parked in driveway at a slight incline. All windows and doors where closed. This has caused $2,700 electrical damage to modules located under front passenger seat. These modules alert me about esp/ABS and park brake as well as a module that powers the vehicles mmi/navigation and stereo system. None of these function anylonger. I don't know where the water entered my vehicle. Is Audi responsible? This appears to be a design flaw.”
NHTSA complaint #10458904, filed 2012-05, 106,000 miles“My Audi A6 stayed overnight in the rain. In the morning the driver's footwell was full with 2 inches of water. Audi recognized that sunroofs have a drain line that is installed with a kink to limit noise going back into the car. The problem is the kink prevents debris from evacuating correctly.”
