5/5 Overall
NHTSA 5-Star Safety Rating
The 2023 Chevrolet Blazer has 2 recalls, both involving the same serious risk: the driver-side half-shaft can disengage from the drivetrain, causing a sudden loss of drive power or an unexpected rollaway when parked.
In one case, a retaining ring may be missing from the half-shaft assembly, allowing the inner joint to separate. In the other, an incorrect sun gear inside the transmission can cause the half-shaft to pull free from the transmission itself. Both failures lead to the same outcome, and prior repair attempts did not fully resolve the issue across all affected vehicles.
