The hazard
On certain fire trucks, specific operating conditions (such as tight, successive, highly banked curves in opposite directions), could trigger unintended Electronic Stability Control (ESC) system intervention. As a result, the ESC may unnecessarily apply one of the front brakes in order to correct the perceived oversteer condition. This may cause the vehicle to deviate from the intended path, thereby increasing the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the ESC module.
