Some 2020-2022 model year Chevy Trailblazer owners may have observed a squealing sound coming from the front of the vehicle under light braking. While some brake noise is normal, GM has decided this squealing condition was loud enough to warrant a fix.
According to the GM Techlink service info site, Chevy Trailblazer drivers may notice a brake squeal sound at low speeds “when the brakes are first applied or lightly applied, such as when exiting a parking lot or during first use after sitting overnight.” This noise will be heard emanating from the front of the vehicle.
To remedy this problem on early Chevy Trailblazer models built before March 20th, 2020, service technicians are advised to apply grease on the caliper pad spring abutments and anti-rattle clips, and replace the front brake pads. On models built between March 20th, 2020 and February 14th, 2022, technicians will apply grease to the same parts, but reinstall the original brake pads. Vehicles built after February 14th, 2022 may not experience this condition, so in this case, technicians are advised to refer to other Trailblazer service info related to brake noises.
This problem affects some 2020 to 2020 model year Chevy Trailblazer models. A recall, customer satisfaction program or service bulletin for this condition has not been issued and likely will not be necessary given the relatively straightforward fixes outlined in the Techlink article.
The Trailblazer crossover rides on the GM VSS-F platform, with production of North American-spec models taking place at the GM Bupeyong plant in South Korea. GM is set to expand production of the nameplate at the Korean facility for the 2023 model year, adding some 6,000 units to the production schedule. Pricing for the 2023 Chevy Trailblazer will start at $22,995 including the mandatory destination and freight charge, making it the most affordable GM vehicle available in the United States.

I don’t believe there is a 2020 model Trail Blazers, first model yr is a 2021 which I have. Maybe for a different market before coming to the states.
Yeah, it launched one MY early in China.
My Son has a 2021 and never had any issues with brake noise.
lol there is no true fix for this because of the pad material that GM uses. I'm an advisor for a NE Ohio Chevy dealer, and have been through this with just about every vehicle GM makes as of late up to and including the C8. I can put brakes on it all the way around, and it still comes back. There are multiple bulletins out there that GM has released, specifically pointing out the pad material and suggesting an "upgraded design" that the customer has to pay for after 7500 miles, and it still doesn't fix it.
This squeak is across multiple gm products including 2019. Not every cold start backing out of the garage but it does happen. My neighbor across the street has a 19 Cadillac and it makes the squeak backing out of their garage every once in awhile like mine.
On the Traverse forum, some dealers were replacing the pads to fix the issue.
However, once I backed out and start to go forward and brake at the stop sign about 300 feet, this problem goes away and never happens again during my trips. Only happens after setting overnight and backing out.
I replaced my front disc pads on my 09 Colorado at 83k miles and replaced with the same OEM pads. No squeak.
The squeak isn't an issue to me... JMO
I have had squealing front disk Brembo brakes on occasion from my 2015 ATS. Back out of the garage slowly and they squeak then nothing when going forward. No big deal.

How about the grabby brakes. First few brake periods can send u lurching forward.very sensitive
My '22 LS Trailblazer squeaks. I've had the caliper pads greased once already.
I have had my 2022 Trailblazer at the dealership 3 times over brakes. The first time they greased them, started squealing a week later, the second time they were supposed to replace them but greased them again, week later squealing again. Third time they replaced with GM brakes due to AC Delco brakes not available and they are squealing yet again. I feel like this car is going to be a lemon.
i have a 2022 trailblazer not a bad suv except for the brakes they work good most of the time but sometime they are touchy and grab and like to put you through the windshield. have had it back to the dealership and they said that, that is the way they are . not a good answer
