Tires

Owners may contact GMC customer service at 1-800-462-8782; and Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N212343560.
Child Seat
11/05/2023
General Motors, LLC (GM) is recalling certain 2020-2023 Chevrolet Equinox and GMC Terrain vehicles. The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage Systems."
How they fix it: Owners are advised to install child seats using the vehicle's rear seat belts until the remedy is complete. Dealers will inspect the latch anchorage bars, and remove and replace the finish, as necessary, free of charge. Owner notification letters were mailed June 2, 2023. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232403240.

What this free check does not include
We only show free U.S. government data: safety recalls, owner reports, crash tests, and fuel economy. We do not show prior accidents, flood or salvage titles, odometer rollback, insurance history, or a “should you buy” verdict on a specific listing. For that kind of check on one car for sale, use the VINly app.
BEFORE YOU BUY
Confirm the recalls were fixed
This model has 2 open NHTSA recalls (including the tires). Recall repairs are free at the dealer, so ask the seller for proof the remedy was performed, or verify by VIN at nhtsa.gov before you buy.
Watch for a pending investigation
NHTSA has an open investigation covering this model. A recall can follow an investigation, so check nhtsa.gov for the latest before you commit.
Test-drive the basics
Cold start, full-lock steering both ways, firm brakes with no pulsing, smooth shifts, and every electronic feature. Warning lights should come on at key-on, then go out.
Check the title and the VIN
Confirm the title status in hand matches the listing, and that the VIN matches across the dash, door jamb, and title. VINly does not show ownership or accident history, for that, run a paid report like Carfax.
Ask the seller the right questions
Why they are selling, any service records, accident or panel-repaint history, how many owners, and whether any open recalls were completed.
See the full used-car inspection checklist. None of this replaces a hands-on inspection by a mechanic.
