ABS module could short and cause fire
The official recall notice reads as follows: “On certain vehicles, the brake hydraulic electronic control unit (HECU) could short circuit.” The risk is that “A short circuit could create a fire risk, even while the vehicle is parked and turned off.”
The brake hydraulic electronic control unit is the piece of hardware that controls anti-lock brake operation, which means stability control systems as well. It has solenoids that adjust brake pressure going to each wheel to prevent lockup.
Brake fluid passes through the module. That fluid is only moderately flammable, but when combined with a short circuit and electrical fire, it can ignite.
Hyundai Canada sent us the following statement about the recall:
“To ensure the safety of its customers, Hyundai Motor North America is initiating a safety recall to address a condition involving the Anti-Lock Brake System (“ABS”) modules in certain Hyundai vehicles produced for sale in the U.S. and Canadian markets. The recall population includes approximately 326,942 vehicles in Canada and 1,642,551 vehicles in the U.S. There are no crashes, injuries, or fatalities attributable to this condition.
“The subject vehicles are equipped with Anti-Lock Brake System (“ABS”) modules that could leak brake fluid internally and cause an electrical short over time. An electrical short could result in significant overcurrent in the ABS module increasing the risk of an engine compartment fire while parked or driving.”
Hyundai and Kia have announced a fix for the issue. Customers will be directed to a dealership to have the HECU fuse replaced at no cost. Both automakers recommend parking outdoors and away from other vehicles or structures until the recall repairs have been completed, but Hyundai has said that owners can continue to drive their vehicles until the fix has been done.
