ONLY A MONTH AFTER PURCHASING MY VEHICLE I STARTED TO FEEL A WOBBLE IN THE FRONT END WHEN ACCELERATING UP HILLS AND TURNING WHILE ON THE GAS. I TOOK IT TO THE DEALER AND THEY CHANGED OUT THE FRONT TIRES STATING THAT THE PROBLEM HAD BEEN FIXED. ONCE AGAIN WHILE DRIVING THE PROBLEM PERSISTED. I TOOK THE CAR BACK TO THE DEALER AGAIN AND THEY SAID THAT THEY COULD NOT FIND ANYTHING WRONG AND SUGGESTED THAT I MAKE AN APPOINTMENT TO GO FOR A DRIVE WITH THE MECHANIC TO SHOW THEM WHAT IS HAPPENING. I MADE AN APPOINTMENT. A DAY BEFORE THE APPOINTMENT I RECEIVED A CALL FROM THE DEALERSHIP STATING THAT AN EMPLOYEE RECENTLY PURCHASED THE SAME CAR AND THEY ARE HAVING SIMILAR DIFFICULTIES. THEY FOUND ONLINE THAT GMC WAS REQUESTING INFORMATION FROM DEALERS ABOUT THE PROBLEM AND WAS TOLD THAT I NOW NEED TO WAIT FOR GMC TO COME UP WITH A SOLUTION. MY CAR SHAKES EVERY TIME THAT I DRIVE IT, IT'S AWFUL, AND IT ONLY HAS AROUND 6,000 MILES ON IT. I'M NOT SURE WHAT TO DO BECAUSE THE DEALERSHIP TOLD ME THAT I HAVE TO WAIT FOR A SOLUTION. THEY ARE NOT EVEN TRYING TO FIX ANYTHING AT THIS TIME. PLEASE HELP.

23V339000 · Child Seat:vehicle Latch Anchor

May 11, 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."

Consequence & remedy

Consequence: The inability to install a child seat with the LATCH anchorage bars could result in an unsecured child seat, increasing the risk of injury in a crash.

Remedy: 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.

Consequence & remedy

Remedy: GM will notify owners, and dealers will inspect the start-stop transmission accumulator and replace it if any bolts are missing, free of charge. The recall began December 15, 2020.
