The contact stated while driving at an undisclosed speed, the contact approached a stop sign and the vehicle stopped as needed; however, after the contact depressed on the accelerator pedal, the vehicle began to misfire and shuddered for several minutes. The contact took the vehicle to the local dealer who inspected the vehicle and diagnosed that the failure was related to TSB 05-16-2 (moisture build up on the plugs and on the cylinder) that caused the vehicle to misfire. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 40,526.”
