Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Pursuant to outstanding recall repair: Fuel tank leaks substantially when filled over 1/2 tank. Zimbrick Audi of Madison, WI confirms symptom, and confirms that fuel tank needs to be replaced pursuant to faulty rollover valve nipple. Audi of America is not currently offering a resolution as they claim replacement fuel tank is no longer available. The car has been unavailable to me for over a week. There is no resolution in sight.

Too few reports in this category for a page of its own — they appear in the full complaint list.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
