Deaths

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.

Complaints fell 39% year on year: 37 in the twelve months to 2026-Q2, against 61 in the twelve before.

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 186.

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 55.

60 45 30 15
19 20 21 22 23 24 25 26

This is the year the complaint was filed, not the year the failure happened. The range runs from 2019 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 2019 Chevrolet BLAZER, and it is a separate question from what owners report going wrong later.

Test SUV AWD SUV FWD
Overall
Frontal crash
Frontal, driver
Frontal, passenger
Side crash

Rollover

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.

TIRES

21V115000 · February 25, 2021

The defect
General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT4, XT5, Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, Traverse, GMC Yukon, Yukon XL, 2018-2021 Chevrolet Express, GMC Savana, 2019-2020 Chevrolet Blazer, Silverado 1500, GMC Acadia, Sierra 1500, and certain Continental tires sold to the aftermarket for various model year 2018-2021 vehicles. The affected tires were cured for too long during production.
The risk
Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.
The remedy
GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.

SERVICE BRAKES

crash

Without warning, the brake pedal on my 2019 Chevy Blazer became hard, almost as if the car was turned off. I was unable to stop and slowly rolled into the back of a semi stopped at a stoplight. This was moments after exiting off of a major highway and could have been much worse. The car was taken to a mechanic and it was determined to be a failure with the brake booster. GM has issued recalls for this problem in several other models but the Blazer has been excluded. Based on online forums and complaints of multiple other Blazer owners, it seems obvious that Blazers should have been included in the recall.

Every Chevrolet on this site — 304 vehicles.

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.
