- Is the airbag light off, and were any airbag recalls done?
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Any steering noise, wander or power-steering warning? Has the steering rack or pump been replaced?
- Buick sent dealers 1576 repair notes for this car. Was this one done: “Notchy or Stick/Slip Feeling in Steering Wheel Near the Center Position”?

How serious. Out of all 17 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 3K to 15K miles (6K to 25K km) on the car (15 of all 17 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.
