Questions to ask the seller
- Were recall 25V900000 (back over prevention) done? Ask for the dealer printout, or check the VIN.
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Has it ever braked hard for no reason? Ask whether the safety-system software was updated.
- Do the brakes feel even, with no ABS or brake warning light? When were the pads and brake fluid last done?
- Audi sent dealers 846 repair notes for this car. Was this one done: “This bulletin provides information for when there are noises when braking, and the brake pad…”?
From this year's own recalls, top problems, top repair bills and Audi's repair notes. Recall repairs are free at any dealer.
How serious. Out of all 3 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
