2014 Audi Q5Recalls, problems, MPG & safety

“I am filing a safety complaint regarding a progressive engine defect. Beginning as early as 2019 (approximately 84,000 miles), I repeatedly reported excessive oil consumption and related engine concerns to authorized Audi dealerships. These complaints continued over several years. At no point was I informed that these symptoms could be associated with a known defect pattern or progressive engine failure.

Both establishments have deemed the vehicle unsafe to drive due to this specific issue. The manufacturer (Audi of America) has been made aware of the issue through their dealership network. They have acknowledged the defect by offering a "goodwill" repair to replace the subframe, confirming their awareness of this failure mode. However, the manufacturer has made this safety-critical repair contingent on the owner first paying for several thousand…”
