2007 Lincoln MKX Speed Control & Cruise Problems

TL* THE CONTACT OWNS A 2007 LINCOLN MKX. THE CONTACT STATED THAT WHILE DRIVING 3 MPH, THE VEHICLE ACCELERATED INDEPENDENTLY AND CRASHED INTO A TREE. THERE WERE NO INJURIES. THE VEHICLE WAS TOWED TO A DEALER FOR DIAGNOSIS BUT THE CAUSE OF THE FAILURE WAS UNDETERMINED. THE VEHICLE WAS REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 34,000.

OUTPUT SPEED SENSOR FAILURE, DUE TO A KNOWN TENDENCY TO SHORT IN THE SENSOR WIRING FOR 2007 LINCOLN MKX AND FORD EDGE VEHICLES. THIS WILL RESULT IN THE WRENCH ICON TO LIGHT UP ON DASH AND VEHICLE WILL SPEEDOMETER WILL BE STUCK AT 0. THE WORST AND MOST DANGEROUS SYMPTOM, HOWEVER, IS THAT THE VEHICLE WILL THEN BE STUCK IN 5TH GEAR, RESULTING IN EXTREMELY SLOW ACCELERATION FROM A STOP OR LOW SPEEDS, ESPECIALLY ON INCLINES. IF YOU PUT THE VEHICLE IN PARK AND THEN SHIFT INTO DRIVE, IT WILL RESULT IN A HEAVY 'LURCH' AND VERY LOUD THUD, THAT FEELS LIKE THE VEHICLE IS BEING REAR ENDED. DRIVING A BIT IN REVERSE, THEN POWERING OFF AND RESTARTING SEEMS TO EVENTUALLY CLEAR THIS STATE AND RETURN TO NORMAL OPERATION, UNTIL IT HAPPENS AGAIN. HAS HAPPENED 3 TIMES IN THE LAST 2 DAYS. THE FIRST TIME IT HAPPENED, IT NEARLY CAUSED AN ACCIDENT AS I WENT TO CHANGE LANES ON THE FREEWAY AFTER SLOWING DOWN IN HEAVY TRAFFIC. THIS CAN ALSO BE EXTREMELY DANGEROUS MAKING RIGHT TURNS WITH ONCOMING TRAFFIC, OR LEFT TURNS WITH APPROACHING TRAFFIC. THIS IS A KNOWN DEFECT, DUE TO POOR SENSOR WIRING\HOUSING, AND POSES A DEFINITE SAFETY THREAT. THIS SHOULD QUALIFY FOR A RECALL. *JS
