Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin provides customer information for rear unwanted automatic braking, usually when reversing out of a garage or driveway.

The failure pattern owners describe
Owners of 2023 Chevrolet Trailblazers report brake squealing starting early in the vehicle's life—as soon as 2,000 miles—and progressively worsening despite repairs. The noise is loudest at low speeds (parking, drive-thru, stop-and-go traffic) but escalates to occur at all speeds by 9,000 miles. One owner describes it as loud enough that everyone in the pickup line can hear it; another compares it to a 15-year-old car.
Dealerships have attempted rotor resurfacing and pad replacement, which provide only temporary relief lasting a few months. Multiple owners report being told the squealing is normal for the metal brake pads installed as original equipment, though owners find this claim difficult to accept in a new $30,000 vehicle.
More concerning: dealerships cite a service bulletin from GM instructing them not to attempt further repairs until engineering develops an improvement. One owner was explicitly told "If vehicle returns after the bulletin has been performed, DO NOT attempt any further repairs. Engineering is working on an improvement." Owners also note that recalls exist for 2020–2022 model years but not yet for 2023.
One owner reports concurrent ABS warnings and a soft brake pedal during braking events. Another notes reduced braking performance and inconsistent brake grab. Dealership service departments have refused warranty work, claimed no safety issue exists, and offered no timeline for resolution.

Failure modes owners describe
Persistent brake squealing
High-pitched squealing during braking, especially at low speeds (parking, drive-thru, stop-and-go traffic). Owners report the noise persists despite rotor resurfacing and pad replacement attempts. One owner notes the squealing progressed to all speeds by 9,000 miles. Dealership technicians have stated Chevy is aware of the issue but has issued guidance not to attempt further repairs pending engineering review.
When: Starts early: 2,000–5,000 miles; worsens over time
Symptoms owners cite: High-pitched squealing during braking; Most noticeable at low speeds; Progressive worsening over time; Continues despite rotor resurfacing and pad replacement
Repairs/costs cited: Rotor resurfacing (temporary relief only); pad replacement attempted but ineffective; dealership greasing mentioned by one owner; no permanent fix available
Recalls/TSBs owners mention: Service bulletin issued; GM instructed dealers not to attempt further repairs pending engineering improvement. No recall issued for 2023 model (recalls exist for 2020–2022 model years only). Dealerships claim no safety issue identified.
Brake grinding and metal-on-metal noise
Owners report metal grinding sounds accompanying or replacing squealing, particularly at low speeds. One owner at 9,000 miles noted grinding in addition to constant squeaking. Dealerships have stated metal brake pads are installed as original equipment and that grinding is normal, but owners find this claim implausible for a new vehicle.
When: Coincides with or follows squealing onset (2,000+ miles)
Symptoms owners cite: Metal-on-metal grinding noise; Occurs during low-speed braking; Accompanies high-pitched squealing; Metal sound intensifies with continued use
Repairs/costs cited: Dealerships claim no repair available; state metal pads are original spec and grinding is normal
Recalls/TSBs owners mention: None documented beyond assertion that grinding is expected with the pad material used
ABS warning light with soft brake pedal
One owner reports ABS system flashing warnings during quick restarts and when holding the brake pedal, accompanied by loss of brake firmness (no 'sponge' or cushion in pedal feel). This occurred alongside constant brake squealing.
When: Concurrent with brake squealing issues
Symptoms owners cite: ABS warning light flashing at quick restarts; ABS warning light during sustained brake application; Soft or spongy brake pedal feel; No pedal firmness when ABS warning occurs
Repairs/costs cited: Issue documented at every maintenance inspection with no flaw found by dealer
Reduced brake performance
One owner reports brakes are not performing as well as when new, concurrent with squealing and after multiple dealership visits. Another owner notes brakes 'grab' inconsistently.
When: Progressive after initial squealing onset
Symptoms owners cite: Reduced braking responsiveness; Inconsistent brake grab; Concern about safety as noise worsens

What owners are reporting 4 most recent
The brakes have been making a loud squeeling when I slow down. This has occurred since I bought the vehicle. The dealership has reviewed it multiple times and state they do not know what is causing it or how to fix it. The last time the tech stated there is nothing they can do. Now the brakes aren't performing as well as they did and it is concerning.
I have a 2023 trailblazer rs bought brand new. Currently has 12776 miles on it and for atleast the last 5000 miles I've noticed the breaks squeeling. Esp when I'm going slow speeds. I first thought maybe it was the weather or something. Moisture..whatever because this car is so new I just brushed it off. But it has progressively gotten worse and louder. Which is super frustrating when I'm picking…
Brakes have been squeaking since about 2,000 miles at lower speeds (parking, drive-thru, stop-and-go street traffic, etc.). Took my car into the dealership at around 7,000 miles. Dealer acknowledged the issue and says that it's due to the material that the brakes are made of. They also stated that Chevy is aware, but isn't doing anything to correct the issue. The dealership did nothing to help…
The brakes on my 2023 Chevy Trailblazer LT. At slow speeds the brakes sound like they are metal on metal and make horrible noise. I have only had this vehicle for 6 months. I did notify the dealer they said they can grease them and they would do it again. And that the only recall fix was for 2021 and 2022 trailblazer having this issue not the 2023 yet
