2023 Chevrolet Blazer recalls

Recall 23V-172: Power Train

Reported Mar 16, 2023 · 8,744 vehicles affected · General Motors, LLC

Problem: General Motors, LLC (GM) is recalling certain 2023 Cadillac XT6, GMC Acadia, Chevrolet Blazer, Traverse, and 2022-2023 Cadillac XT5 vehicles. The transmission may have been built with an incorrect sun gear, which can result in the driver-side half-shaft disengaging from the transmission.

Risk: A half-shaft disengaging from the transmission can result in a loss of drive power or vehicle rollaway when the vehicle is placed in park. Either of these scenarios can increase the risk of a crash.

Fix: Dealers will replace the sun gears, free of charge. Owner notification letters were mailed on July 27, 2023. The remedy is expected to become available August 31, 2023. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GMC's number for this recall is N222389310.

Service Brakes · reported Aug 29, 2026
Multiple warning lights on the vehicle stating the ABS brake system was not functioning, the letters brake showed by the gauges but it was not the parking brake because I put that on to check it and it was a different warning light. The lane assist was not functioning. In January I had the brakes looked at because they are squealing anytime you use them. The brake shop I took it to told me this is a known issue and the brakes are fine and that there was no way to stop the squealing because my brakes still had 80% of their pad. On multiple occasions when I’ve need to brake hard quickly the…
Forward Collision Avoidance · reported Aug 11, 2026
I am reporting a recurring safety issue with the Forward Collision Alert/Automatic Emergency Braking system on my 2023 Chevrolet Blazer 2LT.

The red collision warning will illuminate and the system will beep even when the roadway is clear. More concerning, on three separate occasions the vehicle has unexpectedly applied the brakes extremely hard while I was driving in traffic despite there being no obstacle or imminent collision. The most recent incident…
Engine · reported Aug 2, 2026
The vehicle’s radiator developed a coolant leak that was discovered and confirmed by the dealership during a routine oil change, tire rotation and state inspection. There were no warning lights, warning messages prior to the dealership discovering the leak. The radiator required replacement. The dealership also told me that they had the replacement radiator on hand because this type of radiator failure had been occurring fairly often with this type of vehicle. The radiator failure presented a potential safety concern because a coolant leak can worsen without warning and result in a sudden…
