Kia Optima Recall 23V652: Brake control module short can cause engine fire

NHTSA campaign 23V652, reported September 25, 2023, 1,730,192 vehicles potentially affected.

What this recall means for you

The hydraulic electronic control unit (HECU), which runs the antilock brake and traction control system, may develop an electrical short. That short can start a fire in the engine compartment, either while the vehicle is parked or while it is being driven, which raises the risk of injury.

Until the repair is done, park your vehicle outside and away from buildings and other structures. The fix is free: an authorized dealer will replace the HECU fuse at no cost to you. Owners who have not yet received a notice can call Kia customer service at 1-800-333-4542, and you can check your vehicle identification number (VIN) for open recalls.
