Hyundai unstable electrical ground may cause the vehicle to enter a fail-safe mode with reduced acceleration and power.
The short version
Hyundai Motor America reported a problem with the module onboard (obcm). Here is what owners need to know.
An unstable electrical ground may cause the vehicle to enter a fail-safe mode with reduced acceleration and power. In certain conditions while in fail-safe mode, the vehicle may accelerate after the gas pedal is released.
Unexpected acceleration following gas pedal release can increase the risk of a crash.
Take it to a dealer — they will update the EPCU (Electric Power Control Unit) software and repair the ground wiring, free of charge.
