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.
