Problems with the Seats

Sitting in the Blazer should make a driver feel comfortable and safe, but neither is true.

Car Connection claims, “But it fits the Blazer with narrow seats that aren’t shaped as well as they should be.”

Sitting in the seats is more than uncomfortable, it’s scary. NHTSA Campaign Number 20V811000 shows that GM equipped this SUV with the wrong bolts at the fastening locations where the seat belt gets secured. If the wrong bolt is used, the seat belt might not remain attached, leaving passengers to fly free in an accident. This doesn’t sound like something any car should be dealing with, further proving that Chevy has created a massive lemon.

Problems with the Electrical System

It turns out that the electrical system is just as much of a problem with the Chevy Blazer models, leaving customers quite frustrated.

Here is one Car Problem Zoo complaint. “While driving the whole dash goes blank for a few second, then it reboots and eventually most of it comes back. However, it did this repeat this cycle and cannot tell if my signals are working or what my speed is. I have a video of it happening. The car has 2,700 miles. . I am taking to a dealership.”

Not surprisingly, the 2020 Chevy Blazer was known for electrical system problems that might not even be repaired in the newer SUVs. A class action lawsuit shows that owners were dealing with the car stereo reaching max volume levels unexpectedly without any input. This sudden loud sound is distracting and could easily lead to an accident. It appears there’s no better way to create a “head-turning form” than to blast out the eardrums of the user.

    I bought my 2021 Chevy Blazer at the end of January 2022 brand new off the dealer lot. I have since had all the dash lights go off a total of 8 times in a 10-15 minute to drive home from work. I have complained to my dealer that I felt the car jerking like the transmission was missing. I had the vehicle back at the dealer because there was a constant, loud ticking noise coming from the car each time the wheel was turned. Finally, they told me I had an axle that was bad. After waiting a week to have the axle replaced, they informed me that they found another problem with a wheel bearing. This was all before or at 5,000 miles. I now have only 7,000 miles on this vehicle in 9 months, and I have almost bald tires. I have also complained that the rear end of the vehicle lags as though power in not distributed correctly. They tell me that there is nothing they can do if the vehicle does not show any warning lights on the dash. They say that there is not a problem, but I can feel it when I drive!! I owned my last vehicle for 12 years. This new Blazer is less smooth to drive than my 2010 Dodge Journey. I cannot afford to purchase another vehicle, and I am becoming very worried that this purchase will not last me the next 5 years, let along 12 like my other. This vehicle cost over $50,000.00 and drives like it should have been less than ten.

    Absolutely horrendous vehicle. Brakes squealing and grinding at the 5,000 mile marker, electrical is shot. The seats adjust themselves when the car is off! Car did not stay locked (more electrical issues) and was gone through by someone on the street!!

    I bought a 2021 Blazer RS 3 months ago. A week ago I was standing just outside the passenger door with the keys in my pocket. Vehicle shut off after a couple minutes. When I turned the vehicle back on, the seats and mirrors wouldn’t reset to my position setting and the AC will not get cold. It just blows air. The seats now work to my settings but the AC still only blows air. Not getting cold. I noticed after about a week it was issuing the rubber piece on the corner of the gate that makes it sit girly against the vehicle when closed. Also noticed inside the door jams huge bubbles of paint near the rubber door seals.

    I have a 2021 Blazer 2LT. The fender/bumper pointed area just below the headlights both have broken clips and I can no longer go through the car wash! The dealer of course blamed the carwash. But if it were not loose and sticking out how would a piece of felt even get stuck there??? They want $150 to glue it! And said it would be a ‘temporary’ fix!!! SMH

    I have a 2021 Blazer that I bought in February 2021. I had to take it in the first time with an electrical issue having it less than a month and under 600 miles. It’s been in several times since. The dealership has now had my vehicle since the end of June and it’s mid August. Still no answers or when I’ll have it back. Looking more like I won’t have it back. I’m paying for a car I don’t even have. This is ridiculous!
