2023 Chevrolet Blazer recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. The left-side half-shaft assemblies may be missing a retaining ring.
What could happen: A missing retaining ring on the half-shaft can cause half-shaft inner joint separation, resulting 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.
The fix: Dealers will replace the left-side half-shaft assembly, free of charge. Owner notification letters were mailed February 23, 2023. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N222390180.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2023 BLAZER.
- Book a repair at any authorized Chevrolet dealer. Quote NHTSA campaign 23V042000 (manufacturer code N222390180).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-222-1020.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
