Erratic Operation of Electric Drive Motor
Drive Train, September 6, 2011
RepairPal Expert Overview
Our Quick Take:
If the engine were to stall when the brake is NOT applied, the electric drive motor could unexpectedly move the vehicle in the opposite direction of the selected gear.
What Should You Do?
Honda will notify owners of affected vehicles beginning September 30, 2011. If you are experiencing stalling or erratic operation of the electric drive system, or you don't receive notification and you feel you should have, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
If the engine were to stall when the brake pedal is NOT depressed, there is a chance the engine control unit software may cause the electric motor of the hybrid system to move the vehicle unexpectedly in the opposite direction of the selected gear. Unexpected vehicle movement could increase the risk of a crash. Dealers will update the ECU software to correct this concern. The Honda recall number is R94.
