- Chevy recalling 20 Blazer EVs over a parking brake wiring fault.
- Fault may trigger brake failure or random engagement while driving.
- Root issue tied to incorrect part ordered through GM’s own system.
A small number of 2024 and 2025 Chevrolet Blazer EVs are being recalled over a fault involving the rear parking brake wiring harness. The defect could either stop the brake from working entirely or cause it to engage when it shouldn’t, posing potential safety risks in both cases.
According to GM, the problem stems from repairs linked to a previous recall to fix the same problem in the summer of last year. During that process, some vehicles received the wrong replacement part, a mix-up caused by an issue in the company’s electronic parts catalog.
Although the earlier recall required a harness replacement, the system allowed dealers to order a component that didn’t meet design specifications.

GM explains that the incorrect harness follows a different routing path, one that doesn’t adequately protect the wires from flexing under normal use. This increases the risk of shorting or breakage during everyday driving.
If the parking brake engages while the vehicle is moving, it could heighten the chance of an accident. Conversely, if the brake fails when the car is parked and unattended, it might roll away. In some instances, drivers may also find themselves unable to shift out of park.
Limited Scope of Impact
The good news for Chevrolet is that this isn’t a sweeping recall. Only 20 Blazer EVs are affected. That includes 15 units from the 2024 model year, produced between July 3, 2023, and March 3, 2024, and five 2025 models built between September 11 and October 9, 2024.
The issue came to GM’s attention in mid-October when a brand quality manager submitted a report after discovering the electronic parts catalog had allowed dealers to order an incorrect wiring harness. While the brand isn’t aware of any accidents related to the fault, it has rightly decided to issue a recall.
Starting March 9, affected owners will receive notifications. Dealerships have been instructed to replace the harness with a corrected version that includes an overmold sleeve. This added layer helps prevent future failures caused by wire flexing.
