NHTSA's VIN data lists these trims for the 2021 Traverse. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 92 complaints with NHTSA about the 2021 Traverse. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 3 recall campaigns for the 2021 Traverse over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
General Motors, LLC (GM) is recalling certain 2020-2022 Chevrolet Traverse and 2021-2022 Buick Enclave vehicles. The harness connector to the left or right side roof rail air bag may have incompatible electrical terminals, which could prevent the air bags from deploying in a crash.
Risk: Roof rail air bags that do not deploy as intended increase the risk of injury in a crash.
Remedy: Dealers will replace the harness connector to the roof rail air bags, free of charge. Owner notification letters were mailed on April 29, 2022. Owners may contact Buick customer service at 1-800-521-7300 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N212352140.
Braun Corporation (Braun) is recalling certain 2020-2021 Chevrolet Traverse wheelchair accessible vehicles with Power In-floor Ramp conversion. The screw and clip that hold the inner wheel-well plastic shroud in place may chafe against the transmission case, possibly resulting in a transmission fluid leak.
Risk: A transmission fluid leak can cause a loss of drive power, increasing the risk of a crash. In addition, a leak in the presence of an ignition source increases the risk of a fire.
Remedy: Dealers will replace the screw and clip, and inspect for signs of contact with the transmission, free of charge. Owner notification letters were mailed November 29, 2021. Owners may contact Braun customer service at 1-800-488-0359.
General Motors, LLC (GM) is recalling certain 2021 Chevrolet Traverse and Buick Enclave vehicles. During service by dealers, certain vehicles may have received incorrect air bag calibration software that may affect frontal airbag deployment.
Risk: Air bags that do not deploy as intended can increase the risk of injury.
Remedy: Dealers will update the air bag calibration software, free of charge. Owner notification letters were mailed on July 29, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020 and Buick customer service at 1-800-521-7300. GM's number for this recall is N212340220.
