Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have gone gone to the dealer numerous times visits right after I had the scheduled oil changes done. The oil light / consumption issue happens after I've gotten an oil change, but 7,000 miles before the next one is due. I get afraid thinking that my car is out of oil . I do not have any oil leaks. Oil is leaking around ladder frame. This has been a know issue for a few years that I have been having and Audi will not resolve.”
