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.

| Description | I went out to start my car and the light said that it was not reading the key fob because of low battery. I went and got the other key fob which had never been used and had the same result. The car was towed by chevrolet to the dealer and it has been there for over 3 weeks. They found that it wasn't a faulty key fob but it was the receiver that gets the signal and allows the door locks to open and the engine to start. I tried moving the shift lever, stepping on the brakes, trying the remote start on the key fob and nothing would start the car nor would it lock/unlock the doors. It just kept giving me the notice that it couldn't read the key fob. I called onstar and tried the actions they told me but that did not work either and they said to contact my selling dealer. Onstar contacted the chevy warranty number for a tow truck but at 9pm it was too late for them to make a service call. What if I was out in a parking lot or in a remote area and experienced the same problem with no assistance. I have been trying to find out what the dealer is doing to repair my vehicle but I have to call the gm complaint line in order for them to try and contact the dealer about my car. They finally gave me a rental vehicle since the vehicle is less than 1 year old and only has about 6,000 miles on it. |

| Description | When I am accelerating it seems like my car hesitates to get up to speed, at times feels like it is slipping to get traction. I put my car in awd and didn't seem to notice the issue, when put back into 2wd, the issue happens, it is not an every time thing, but enough that my husband, who doesn't drive my car a lot noticed it and a coworker who has the same year as mine also has the issue. Of course when I took it into the dealership to have it looked at the car didn't do it, so as far as they are concerned there is nothing wrong with it, which is not the case. My husband has a 2020 blazer and it doesn't have this issue. I understand that it is a different year, but if it has the same engine and transmission I would think there shouldn't be much of a difference in how they both drive. It's very frustrating to spend this much on a vehicle that I leased in may of 2020 and it has been in twice for this issue and the parking break issue (which gm's reasoning as to why this turns on by itself and does not turn off is bs, there is still an issue with this as well) and when serviced there is never anything wrong with it. So could it be an issue with the transmission, traction control or possibly the engine? |

| Description | Car purchased on 5/19/21 with 117 miles on it. It now has 1153 miles and the brakes are grinding. The chevy dealership states that it needs replacement brake pads, but they are on backorder. I have been uncomfortable driving the car after the dealership said it needed new brake pads and have not driven the car for two days. I can get by another four days, but I have a dr's appointment this coming wednesday that requires a 50 mile trip. |

| Description | The brakes are noisy (like metal to metal, worn out) and the brake pedal is soft. Took the vehicle into the dealer (only 1,000 miles on odometer) they say gm is aware of a problem. How many people will die before this problem is fixed? The problem isn't corrected, and exists today. |

It is just a black screen. When this happened, it caused the steering wheel controls for radio volume and turning the station to not work.

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!!
Very uncomfortable seats and transmission slipping
I have a 2021 chevy blazer premier and my rear brakes are grinding. Is this normal its not even a year old.
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!
