Issues with the Chevy Trailblazer

The problem history of the Chevrolet Trailblazer is an eye-opener. The United States Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) received 1,281 complaints about the first standalone 2002 model.

These covered just about every possible component in the car, with the engine and cooling system topping 158 complaints, exterior lighting 157 complaints, and the fuel system/gasoline, 125 complaints. There were also 14 recalls, 3 related to the powertrain, and 2 to exterior lighting.

There were almost as many complaints the next year (1,265), with 9 recalls. The next year recalls decreased to 2 but there were 1,366 complaints. There were only 2 recalls in 2005, but even more complaints (1,690). Then they started to decrease, with 1,334 complaints but 8 recalls in 2006 and 773 + 5 recalls in 2007.

Things were getting better in 2008, with only 191 complaints to NHTSA and no recalls from General Motors (GM.) Even though the 2020 model was available in the U.S. there are no NHTSA records relating to this model.

What are the most common problems with the 2021 Chevy Trailblazer?

While there are undoubtedly fewer complaints about the Chevy Trailblazer than ever before, the 27 complaints to NHTSA cover a wide spectrum of problem components.

Service brakes hit the top of the list with 10 related problems. Other complaints affect airbags, the electrical system, the engine, equipment, exterior lighting, forward collision avoidance, the fuel/propulsion system, the structure of the vehicle, tires, vehicle speed control, visibility/wipers, and the wheels of the car.

2021 Chevy Trailblazer Brake Problems

Brake problems are not something any car owner can ignore. If your brakes fail, you are in danger. So, complaints of brakes failing or reduced functionality are a major issue. While one complaint said the brakes squeaked, more said theirs failed.

A complaint made in September 2021 described a 3-car collision that resulted in the complainant’s car catching on fire after brakes failed.

Another complainant states that the dealer won’t do anything about brake-squealing issues because, “there is no bulletin out for the car model.”

An eleventh service brake complaint is listed in “unknown or other.” This reports a loud popping noise from the stereo speakers when applying the brakes, The complainant says there are several other similar complaints on the Trailblazer forum.

2021 Chevy Trailblazer Electrical System Problems

These complaints range from major to minor.

The complaint mentioned above that resulted in a fire after brakes failed is also listed as an electrical system fault. Other issues relate to popping sounds before the power steering and brakes failed, the auto-stop not functioning properly, and noises made by the speakers in the car.

2021 Chevy Trailblazer Structural Problems

Structure problems are also varied, but with no apparent link. The first complaint in October 2020 is about bubbling paint. The problem stems from July that year, and when the complaint was made, the claim to GM was still open.

Another much more serious complaint reported the panoramic moonroof of the car exploding from the inside out. It reportedly sounded like a gunshot and the glass shattered!

The third complaint relates to multiple issues including faulty emergency braking,  continuous noise, tire pressure that doesn’t work, and a bumper that is coming loose. This complainant claims that the dealer “put a bandaid on my problem and I still have all of these issues.”
