Three problems related to check engine light on have been reported for the 2005 Ford Mustang. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2005 Ford Mustang based on all problems reported for the 2005 Mustang.
The contact owns a 2005 Ford Mustang gt. The contact heard an unfamiliar noise and three of the four tires blew out. After a diagnosis, she was informed that the lower ball joints were faulty. The lower ball joints were repaired; however, the check engine light illuminated two days later. The vehicle was taken back to be repaired and she was informed that the throttle body sensor failed. The contact referenced NHTSA campaign id number 06e089000 (suspension:front). The current mileage was 38,000 and failure mileage was 25,000.
Purchased vehicle in 4/05-problems started in 10/05. Engine light on and engine idle rough on 4 separate occasions. Two sensors, a solenoid, and spark plug replaced on those occasions. Now car is at dealer because it will stall when idle and lose power. This is really not safe when you are entering traffic! still waiting for the outcome of this. The fuel sending unit needed to be replaced due to erratic fuel gauge-the gauge would show empty when the tank was full.
While driving my 2005 Ford Mustang (v6 with 7,000 on the odometer) at approx. 40mph the gas pedal suddenly became totally inoperative. This occurred only once but was followed in two subsequent events with the check engine light coming on and the (yellow wrench light) for the throttle control. This then activated the "limp home" mode. Obviously loosing all gas pedal response while driving was the frightening part of all this.
