When problems show up
Only 11 complaints listed a mileage: too few to say when problems show up.
Questions to ask the seller
- Do the wipers, washers, defrost and mirrors all work?
- Is the stability-control light off on a test drive?
- Any rust or damage underneath, or doors and hatches that don't close right?
From this year's own recalls, top problems, top repair bills and Buick's repair notes. Recall repairs are free at any dealer.
How serious. Out of all 12 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 1K to 25K miles (2K to 40K km) on the car (11 of all 12 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.
Recalls 0
No safety recalls on record.
Recall repairs are free at any dealer. A recall only matters if it's still open on that exact car, so check its VIN.
