A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

Red marks a system with a recall campaign against it. One complaint can name several systems, so these add up to more than 43.

When the complaints arrived

By the year NHTSA received them

By the year NHTSA received them, which is not the year the failures happened. They peaked in 2025 at 15.

16 12 8 4
23 24 25 26

This is the year the complaint was filed, not the year the failure happened. The range runs from 2023 to 2026, the last of them a part year, which is why its column is drawn faint.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA crashes a car into a barrier and a pole and measures what happens to the dummies inside. This is what it awarded the 2023 Chevrolet BLAZER, and it is a separate question from what owners report going wrong later.

A rating belongs to a tested body style and drivetrain, not to the model as a whole, which is why more than one is listed. A dash means NHTSA did not rate that test for this vehicle.

23V172000 · March 16, 2023

The defect
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.
The 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.
The remedy
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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

1 injured

I am reporting a recurring safety issue with the Forward Collision Alert/Automatic Emergency Braking system on my 2023 Chevrolet Blazer 2LT. The vehicle frequently activates the Forward Collision Alert when there is no vehicle, pedestrian, or other obstruction in front of me. 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 occurred on August 11, 2026. I was making a turn through a busy intersection when the Automatic

NHTSA complaint 11756366, quoted in part. Filed by an owner and not verified by NHTSA or by us.

SERVICE BRAKES
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 car had felt like it was shaking and the brakes didn’t feel like they were catching. Vehicle is

ENGINE
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 loss of coolant, engine overheating, or vehicle breakdown while driving. Because there were no warning

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
