Dt: caller is concerned about vehicles burning up. Has not had a problem yet but does not want to wait until something happens. Saw report on cnn.com. Dealer said it was only happening with some vehicles, and it may not be caller's car. Caller saw vehicle on the federal safety agency website. Manufacturer gave caller a reference id 1481671685. They checked his VIN,and his vehicle was not involved in recall. Caller was confused from all the information he was getting from the federal safety agency , the story on cnn, and what ford was telling him.
Consumer drove home, parked the vehicle under the carport, went into the house,then heard an explosion. Consumer looked out of the door and discovered a fire coming from the left wheel well. The fire department responded, extinguished the fire, and the vehicle was totaled. This vehicle not included in the cruise the federal safety agency recall 99v124000. *ak consumer never received recall regarding cruise control. Cruise control failed just as stated in recall.
The speedometer shows a much less speed than actual speed traveling. Contacted a couple of ford dealership who informed me that they do not and cannot fix this problem and I was referred to a local speed test shop. The vehicle was tested on a certified machine, the test results were as follows (speedometer indication/actual vehicle speed): 25/30 30/37 35/43 40/50 45/54 50/60 55/66 60/72 65/80 also, the odometer registers 95 miles for every 100 miles traveled. The vehicle has about 103,000 miles on it, and the malfunction has caused financial problems (speed violation) as well as endangering self and others without even being aware of the fact that the car is traveling at dangerous speeds, especially on 65 MPH and 70 MPH expressways. The test shop informed me that the speed differential increases at higher speeds and could result in speeds way over 30 MPH above the speedometer indication.
Reported by insurance carrier. No safety defect noted.
While driving on highway about 65 MPH with speed control on, consumer stepped on brake pedal to reduce speed, engine shutdown. Consumer had to drive to side of road. After a few minutes engine would start working again. *ak consumer was informed by dealer that cruise control was not a factor, however they could not determine the cause of the problem.
Horn and cruise control work intermittently, air bag light reads code 13 + 34. Short in air bag module, causes light to blink. Dealer stated wire harness needeed to be replaced.
Throttle linkage became detached from accelerator pedal when plastic anchor for the cable failed. This resulted in a very dangerous condition as throttle control was completely lost. Fortunately, the vehicle was brought to a halt without an incident. This was a sudden failure with no warning of a problem. On inspection of the pedal it was obvious that a plastic anchor that connects the throttle cable to the accelerator had broken.it is my opinion that this was a defective part and the expense for reparing it should be the manufacturer's.
