When problems show up
No complaints for this year listed a mileage, so we can't say when problems show up.
Questions to ask the seller
- Were recalls 25V899000 (seat belts) and 25V900000 (back over prevention) done? Ask for the dealer printout, or check the VIN.
- Has it ever braked hard for no reason? Ask whether the safety-system software was updated.
- Any rust or damage underneath, or doors and hatches that don't close right?
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Audi sent dealers 564 repair notes for this car. Was this one done: “This bulletin provides information on document requirements before replacement of the vehicle…”?
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 7 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
