General Chevrolet Blazer EV recall: The rear parking brake wiring harness may become damaged or corroded

Recall published 1+ years ago

The rear parking brake wiring harness may become damaged or corroded, resulting in unintended activation of the parking brake or loss of the parking brake function.

The hazard: Brake system defect

A braking defect prompted this notice. The remedy is free and the appointment is usually short; the risk of leaving it is not proportionate to the inconvenience.

What the notice says: Unintended activation of the parking brake while driving increases the risk of a crash. Loss of the parking brake function while parked can result in a rollaway, increasing the risk of a crash.

Why it matters: A fault in the braking system can lengthen stopping distances or cause a loss of braking. Unlike most vehicle faults, this one gives very little warning before it matters.

What to do about Brakes

General — A braking defect prompted this notice. The remedy is free and the appointment is usually short; the risk of leaving it is not proportionate to the inconvenience.

  1. Book this repair promptly, and in the meantime leave a larger gap than usual to the vehicle in front.
  2. Call any franchised dealer for the brand, give them the campaign number from this page, and ask them to confirm parts are in stock before you book — part supply, not labour, is what delays a fresh recall.
  3. Tell the dealer if you have noticed a soft or sinking pedal, a longer stop, a warning light or a new noise — those symptoms affect how urgently they fit you in.
  4. Do not top up or change brake fluid as a workaround; it will not fix a mechanical or software defect and it may mask one.

Getting the repair booked and paid for

The money side of a vehicle recall is simple. The scheduling side is where people lose weeks.

  • Ask whether the parts are physically in stock before you accept a date. A booking without parts is a wasted morning.
  • Where the manufacturer has issued an interim measure — park outside, do not drive, a software limiter — follow it until the full remedy is done.
  • Reimbursement claims for earlier out-of-pocket repairs go to the manufacturer, not the dealer, and need the original itemised invoice.
  • If you get nowhere, file at nhtsa.gov. Complaints tied to an open campaign number carry weight.

Remedy named in the notice: Dealers will inspect the harness and, if necessary, reroute the harness and install anti-abrasive tape. Any harness that has existing damage will be replaced. Repairs will be performed free of charge. Owner notification letters were mailed on October 1, 2025. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N252503010.
