MY 2005 MERCURY MONTEGO HAS AN INSTRUMENT FAILURE IN WHICH ALL WARNING LIGHTS STAYED ON. ONE LIGHT REMAINED ON AFTER IGNITION WAS OFF. THE BACKUP LIGHTS STAYED ON WHILE IN DRIVE PRESENTING A SIGNIFICANT SAFETY HAZARD. FOR EXAMPLE, A CAR APPROACHING FROM THE REAR, UPON SEEING FAULTY BACKUP LIGHTS ON MAY SWERVE TO AVOID. THIS SITUATION WOULD BE EVEN MORE LIKELY TO HAPPEN AT NIGHT ON A TWO LANE ROAD. NHTSA PREVIOUSLY CLOSED THE ORIGINAL INVESTIGATION DUE TO 'NO SAFETY DEFECT'. THAT REASON WAS BASED ON FORD'S INACCURATE STATEMENT TO ODI THAT THE BA…

TL* THE CONTACT OWNS A 2005 MERCURY MONTEGO. THE CONTACT STATED THAT WHILE DRIVING 30 MPH, THE ENTIRE ELECTRICAL SYSTEM MALFUNCTIONED AND CAUSED THE REAR BRAKES AND INSTRUMENT CLUSTER TO FAIL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER, WHERE A DIAGNOSTIC TEST INDICATED THAT THE THROTTLE BODY AND ALTERNATOR WERE FAULTY. THE DEALER REPLACED THE THROTTLE BODY, BUT NOT THE ALTERNATOR. THE FAILURE CONTINUED. THE VEHICLE WAS TAKEN BACK TO THE AUTHORIZED DEALER, WHERE THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE FAILURE MILEAGE WAS 95,275.

WHEN ACCELERATING THE VEHICLE WOULD BE ROUGH AND INCONSISTENT ALMOST LURCHING FORWARD AT TIMES. THE VEHICLE WOULD DO THIS EVERY TIME IT WAS DRIVEN. AFTER HAVING TO REPLACE THE VEHICLES BATTERY THE VEHICLE WOULD NOT ACCELERATE AT ALL. THE RPMS WOULD NOT GO ABOVE 1000. THE THROTTLE BODY WAS REPLACED AND NOW THE VEHICLE DRIVES FINE. I DO STILL HAVE THE OLD PART. *TR

Owner report 10469140 · 2012-08-03 (August 3, 2012)
THE CAR WAS PURCHASED IN MAY OF 2011. AUGUST 2011, THE TRANSMISSION STARTED TO VIOLENTLY JERK AND ACT AS IF IT WERE IN NEUTRAL. WHEN GRADUALLY APPLYING THE BREAKS, THE CAR WOULD BEGIN TO SHUDDER. THIS WOULD HAPPEN ONLY IF THE ENGINE WAS WARM. BY MARCH 2012, THE SHUDDERING TRANSMISSION AND JERK WAS CONSTANT. I TOOK IT IN TO BE LOOKED AT IN APRIL OF 2012. THE ALTERNATOR WAS REPLACED, DUE TO WHAT WE THOUGHT WAS A BAD BATTERY. THE MECHANIC BELIEVED THIS CAUSED THE TRANSMISSION TO JERK. THE PROBLEM WAS NOT SOLVED. JUNE 2012 THE TRANSMISSION W…
