A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2025 Chevrolet Blazer EV
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Electronic Brake Module Component Failure
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles.

GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until th...
Recalls on the 2025 Chevrolet Blazer EV
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

Brakes
Issue: On certain vehicles, the recall repairs completed by a General Motors dealer during recall N252503010 (Transport Canada recall no. 2025-351) may not have been done correctly. As a result, a second repair is required. On certain vehicles, the parking brake wiring harness could become damaged and/or corroded. If this happens, the parking brake may not work and the vehicle could roll away when it's parked. This problem could also cause the parking brake to apply suddenly while driving. Safety Risk: A parked vehicle that rolls away could create the risk of an injury or a crash. Additionally, a parking brake that self-applies while driving could increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to replace the wiring harness.

When driving slowly waiting a parking lot the vehicle locked up on the brakes with the warning message pedestrian alert. The area was clear.

We discovered the onstar module contrs all of these functions.

1. Vehicle has a horrible squeaking sound coming from the brake pedal area. First dealer diagnosed it as the master cylinder needing replacement. Noise did not go away and GM said that it is normal. The noise is not normal and has never been on any other car I have owned. 2. When reversing, the car sometimes abruptly slams on the brakes as if it is avoiding a collision even though no collision is close to happening. GM refuses to fix the problem.

At a low speed, between 10 and 15 mph, the forward collision system automatically triggered and brought the car to an immediate stop. While we were lucky that no car was following behind us, the passenger and I experienced significant whiplash and lasting back pain as a result of this. The vehicle has not been inspected by anyone, and not been reproduced. The forward collision system flashed (red warning light, alert).

ELECTRICAL SYSTEM
Multiple safety-critical malfunctions have occurred on this vehicle involving unintended braking, unintended acceleration, and false activation of driver-assist systems. These events did not happen at the same time and occurred under normal driving conditions. At various points, the vehicle has suddenly applied the brakes without driver input, including hard braking events that felt like an automatic emergency braking activation when no hazard was present. In separate incidents, the parking brake has engaged while the vehicle was in motion, causing abrupt deceleration. There have also been instances of unintended acceleration where the vehicle surged forward briefly without additional throttle input. These malfunctions appear to be related to electrical or ADAS system faults affecting braking logic and propulsion control. No warning lamps or messages reliably appeared before these events. The issues pose a serious risk to the safety of the driver and others because the vehicle’s behavior is unpredictable and can interfere with safe control. The dealership was unable to reproduce the conditions during inspection, but the incidents have occurred multiple times in real-world use.
