2021 Chevrolet Trailblazer: grinding or squealing brakes

Filed Mar 24, 2026 · Brakes, Electrical · RI

When stopped at a red light & the light turns green & I accelerate, the vehicle does not move. It makes a loud noise and jumps. This happens way too many times. There’s also an issue with the brakes, when you press on them, you can hear something grinding, which should not be happening because I bought the car brand new. Also the brakes have always been super squeaky, which is very frustrating because they should not be with a brand new car once again. The engine light goes on and off randomly and doesn’t say anything.

A loud popping noise heard through the radio when light pressure applied to brakes. Noise loud enough to scare the hell out of all the occupants in the car. Brakes squeaked when car was in reverse. Tried to slow down on wet pavement. Car started to veer to the right. Forward collision warning nor automatic emergency braking worked. Pushed brake all the way to the floor and the car did not slow. Rear ended another car. No airbags deployed. My passenger was okay. I got diagnosed with a concussion. Do not know if the occupants in the other car were injured.

We purchased this 2021 Chevrolet Trailblazer RS new from the dealership and we noticed on the second day of owership that the brakes were "squealing". The dealership initially inspected the vehicle asap and without having to go through the service department. However, the problem not only continued, it persists to this day. Additionally, we just purchased a used 2023 Chevrolet Trailblazer RS (with under 10,000 miles) and are experiencing the identical issues with the brakes squealing.

I have had the 2021 Chevy Trailblazer since May 2021, it has been 15 months, not even a year and a half off the lot and i have had wayyyy too many problems. I have has service the stabilitrak stability control system, service the antilock breaking system multiple times within the first 8-10 months. I had to get a part replaced due to that. The dealership had my vehicle literally for a month after i bought it, had an open tak report through Gm due to my engine light coming on. Gm did not know why it was happening. Had 2 service engine and transmission system alerts. I have had a fuel injector and line replaced as well within the first 6 months. I have had to get the system updated 2 times also. Now August 2022 im having service battery, or starter. Have had my vehicle shut off on me at an intersection then come back on two different times. My breaks have been squealing ever since i got this vehicle. Dealership confirms everything is in good standing. I have not had a vehicle where breaks squeal when i am coming to a stop or backing out of my driveway constantly. Dealership keeps saying oh its just probably dust or dirt, spray them out and it should stop. But, it has not for about a year now! Unbelievable! I am going it to trade this vehicle in. This is wayyy too much to be dealing with when you pay $30 grand on a vehicle!

The brakes make squealing sound when coming to a stop. the dealer has acknowledged the problem and said there is nothing they can do about it and that the problem is normal. It is not normal for brakes to squeak every time the car stops.

Started having issues where all the electronics on the car go blank/dead. So far when this has happened it has not caused the car to be inoperable but in the meantime I have found that the car is leaking (seriously leaking) under the entire drivers seat was soaked. I noticed a while back that it smelled like mildew in the car, I had it cleaned and put a damp rid pouch in there, that basically absorbed in 2 days, but never could find the water. This week I found the water...under the drivers seat. This car has been leaking for 2 years! Last night, I get in the car and plug in my phone to charge and get a message of LIQUID DETECTED Charging is not available because liquid has been detected in the lightning connector. Disconnect to allow the connector to dry. At the same time the phone was plugged in everything started to crackle and squeal through the radio and then no radio at all. There is no way all these components are not damaged. Meanwhile I have take it to a dealer for them to do a "water test", I have zero confidence that this water test will yield any positive results and I am without a vehicle . So I am trying to get this info out anywhere I can to see if other people had similar issues and what can be done. It can not be safe to drive a car that the electronics have water damage.

Brakes squeal when in drive. Any amount of pressure on the brakes the car shakes and a loud squeal begins. Bought the car new in May and this issue started in June. Have taken the car to the dealership since June to try and figure out the issue. Dealership states that rotors and brake pads are in perfect condition, thus the issue being the actual brake component. Dealership will not fix despite car being under warranty because there is no bulletin out for car model. I am very concerned for my safety and the safety of others when driving, especially since the dealership knows their is an issue and will not fix it.

The brakes squeal and squeak when in reverse and applying the brake when going forward at low speed. I have been told there is a GM service bulletin that says this is normal for the brakes to make this very loud noise. I have not seen this bulletin and have not been able to find the bulletin online. At any rate this is not normal for a car with 7600 miles to have brakes that squeal all the time. I have taken this to two different dealers and get the same answer but I do not believe it is proper to make a customer deal with this when they spend close to 30k on a car and you will not fix it because it does not cause a safety issue. Bumper-to-bumper warranty coverage should mean just that.
