Problem
General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT5, GMC Acadia and Chevrolet Traverse vehicles and 2020-2021 Chevrolet Silverado 1500, GMC Sierra 1500 vehicles. The vehicles may have been manufactured with Continental tires that were overcured.

Used 2021 Chevrolet Silverado buyer's checklist

  1. Run the VIN at nhtsa.gov/recalls. 12 recalls this year — ask for proof of repairs.
  2. Safety-critical recall. At least one recall carries a "Do Not Drive" or "Park Outside" warning. Do not buy until the VIN shows it was repaired.
  3. Engine — 403 owner reports. Cold-start the engine, listen for knocking, and watch for warning lights or hesitation on acceleration.
  4. Power Train — 273 owner reports. Test-drive through all gears, including reverse; note slipping, harsh or delayed shifts.
  5. Electrical System — 138 owner reports. Test every window, lock, light, screen and USB port; check the battery age.
  6. Mileage to watch. Owners typically reported problems around 52,696 miles; ask what was repaired near that point.
  7. Before you pay: service records, a history report and an independent inspection.
