“I WAS DRIVING MY 2006 MERCURY MARINER HYBRID DOWN THE ROAD GOING APPROXIMATELY 35-40 MPH. THE VEHICLE SHUT OFF AND THE DASH READ STOP SAFELY NOW. I COULD STILL STEER AND BRAKE. IT WOULD NOT RESTART RIGHT AWAY. I TRIED RESTARTING IN ABOUT A HALF AN HOUR AND IT STARTED. I THEN DROVE FOR APPROXIMATELY 100 YARDS AND THE VEHICLE SHUT OFF AGAIN AND THE SAME DASH READING .

“IN STOP AND GO CITY TRAFFIC GOING ABOUT 1 MILE AN HOUR I BRAKED BUT MY MARINER DIDN'T AND I SLOWLY REAR ENDED ANOTHER VEHICLE. MY ABS SENSOR WENT ON THEN OFF EVENTUALLY AN ABS REGEN LIGHT CAME ON AND I HAD NO BRAKES SO I DROVE ,VERY CAREFULLY, 83 MILES TO MY FORD DEALER ( WITH NO BRAKES) TO FIND OUT THAT I NEEDED A COMPLETE REPLACEMENT OF MY ABS HYBRID BRAKING MODULE. $3900! MY MECHANIC AND I CALLED TWO DIFFERENT JUNK YARDS WHERE WE RECEIVED REPLACEMENTS AND THEY WERE INSTALLED BUT WHEN BROUGHT BACK TO THE FORD DEALER THE UNITS WOULDN'T TAKE THE COMPUTER CODE AND THE (USED) SYSTEMS FAILED. $3900 IS A LOT OF MONEY FOR A VEHICLE, WITH 158,000 MILES ON IT, THAT I BOUGHT USED FOR UNDER $5000. THAT SAID IS THERE ANYWAY THAT THIS ABS HYBRID BRAKE MODULE SHOULD HAVE BEEN ON A RECALL LIST. ARE OTHERS HAVING SIMILAR ISSUES? IS THIS WHY THEY QUIT MAKING HYBRIDS AT THIS TIME? I DON'T KNOW BUT I'M THINKING THIS IS A RECALL ISSUE AT THAT PRICE.”

“AFTER HAVING A NEW WATER COOLANT PUMP (THE FOURTH ONE IN MY MARINER HYBRID) AND A NEW THROTTLE BODY BEING PUT INTO MY CAR BY A FORD DEALERSHIP, MY CAR IS STILL HAVING THE SAME PROBLEMS. NOW A "SERVICE EMISSION SYS" WARNING HAS COME ON, AND BEING UNDER 150,000 MILES STILL I CONTACTED FORD TO SEE WHAT COULD BE DONE SINCE IT WAS "FIXED" BY THEM BUT STILL HAS A PROBLEM RELATED TO THE ELECTRICAL HYBRID POWERTRAIN, AND FORD SAYS THERE IS NOTHING ELSE THAT CAN BE DONE, EVEN THOUGH IT CLEARLY IS UNDER THE WARRANTY THAT THEY CREATED DUE TO THE FAILURES OF BOTH PARTS.”
