Chevrolet is recalling 40,233 2024-2025 Blazer EV SUVs because the rear parking brake wiring harness can become damaged or corroded, which can trigger unintended parking brake activation while driving or leave the parking brake unable to hold the vehicle.

What's wrong?
The rear parking brake wiring harness in the 2024-2025 Chevrolet Blazer EV is the bundle of wires that carries electrical signals to the rear parking brake system. When the driver parks the SUV, those wires help command the parking brake to hold the rear wheels in place. When the driver releases it, the same circuit helps the brake let go so the vehicle can move.
On affected Blazer EVs, the harness is routed through a tight bend that flexes during normal driving. That bend can wear away wire insulation or break wires inside the harness. Once the wiring is exposed or severed, corrosion or an electrical short can make the parking brake apply when it should not, or stop the parking brake from working when the vehicle is parked.
Drivers can see a "service parking brake" warning before the failure. The vehicle can also refuse to shift out of park, which is another sign the parking brake circuit is not responding correctly.

What's the safety risk?
Unintended parking brake activation while driving increases crash risk. If the parking brake does not hold while parked, the Blazer EV can roll away and increase crash risk. Treat a "service parking brake" warning, trouble shifting out of park, or any parking brake fault as a reason to use extra care when parking and schedule service promptly. Repair will be free at any franchised Chevrolet dealer once available.
What should I do?
- Check your VIN to confirm your 2024-2025 Chevrolet Blazer EV is included in this recall.
- Watch for the Chevrolet owner letter mailed on October 1, 2025, or call Chevrolet if you bought the vehicle used.
- Contact a franchised Chevrolet dealer with recall number 25V433 to ask whether the free parking-brake harness inspection and repair is open for your VIN.
- Schedule the parking-brake harness inspection that addresses harness damage linked to unintended parking-brake activation or loss of parking-brake function.
- Avoid driving if the parking brake activates unexpectedly or fails to hold the parked vehicle; call the dealer for guidance.
What happens at the repair
At the dealer, a Chevrolet technician will inspect the rear parking brake wiring harness. If the harness is rubbing, the technician will reroute it and install protective tape. If the harness already has damage, the harness will be replaced. The dealer repair will be free once available. GM says all covered vehicles are under warranty, so there is no separate reimbursement program for this recall. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
