- Is the airbag light off, and were any airbag recalls done?
- Any oil burning, leaks or check-engine lights? Ask for oil-change records.
- Any steering noise, wander or power-steering warning? Has the steering rack or pump been replaced?
- Audi sent dealers 1666 repair notes for this car. Was this one done: “When selecting reverse gear, the picture of rearview camera fails to appear, sporadically”?

How serious. Out of all 10 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.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 2K to 22K miles (3K to 35K km) on the car (8 of all 10 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
In owners' words
Excessive oil consumption. Under normal driving conditions, the engine light came on to add 1 quart of oil 3,000 miles before the next service interval. Only 22,000 miles on the car.
