Questions to ask the seller
- Were recalls 20V668000 (transmission & drivetrain) and 18V576000 (brakes) done? Ask for the dealer printout, or check the VIN.
- Any oil burning, leaks or check-engine lights? Ask for oil-change records.
- Buick sent dealers 696 repair notes for this car. Was this one done: “This Preliminary information communicates that a rotational clicking noise heard after engine…”?
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 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.

Recalls 2
- Transmission & drivetrain · recall issued 2020
The start/stop accumulator endcap may have missing bolts.
- Brakes · recall issued 2018
The rear brake caliper pistons may have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.
Recall repairs are free at any dealer. A recall only matters if it's still open on that exact car, so check its VIN.
