Six problems related to cruise control have been reported for the 1999 Ford Mustang. The most recently reported issues are listed below.
The contact owns a 1999 Ford Mustang. The contact stated that while driving at approximately 70 mph with the cruise control engaged, the vehicle failed to decrease in speed when the cruise control was deactivated. The contact also stated that the brake pedal was applied, but the vehicle failed to stop. The contact shut the engine off while driving in order to stop the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed that the VIN was not included in NHTSA campaign number: 99v062001 (vehicle speed control). The approximate failure mileage was 165,000.
Driving at 75 mph on cruise control. Needed to slow down so tapped brake pedal. Cruise would not release. Hit brake pedal again. No response. Pounded brake pedal and finally cruise cancelled. Dealership found cause to be a broken wire on the brake light switch. Luckily had room in traffic to handle the problem. Next step was to hit cruise off button.
I was driving south on I-85 with the cruise control set at 65 on a clear day. The vehicle went into a skid, and before I could stop the skid I hit the guardrail. There has been a recall on the cruise control for my vehicle (recall 99s09) which I believe contributed to this accident.
Recall 99s09 for the cruise control system not performed due to lack of parts. 99v062.
Vehicle idles too high and does not decellerate when taking foot off of gas pedal, dealership is unable to rectify at this time. Mjs.
Computer controlled idle defective, idle surges unpredictably. Occurs mostly when stopped. Idle fluctuates between 500 and 1000. Sometimes will stall and other times will lurch forward against the brakes. If a/c is turned on, the condition is worse. Car has been returned to dealer and they "can't" fix it because it is a computer controlled problem.
