2007 Mercury Mariner Engine Problems

90sWhile driving, the vehicle will suddenly display a warning message that says “Stop Safely Now”. When this message appears, the hybrid system overheats and the vehicle immediately loses power. The gasoline engine and electric motor both shut down without warning, even at highway speeds. I am forced to coast to the side of the road, which is extremely dangerous in traffic. This happens after the vehicle has been driven for a short period of time. The cooling fans appear to be running, but the hybrid electronics system overheats and triggers the shutdown safety mode. After waiting for the vehicle to cool down, it will restart, but the problem continues every time the car reaches normal driving temperature. This issue matches the symptoms covered under Ford’s previous safety actions and customer satisfaction programs for the 2005–2008 Ford Escape and Mercury Mariner Hybrid (hybrid electronics overheating and shutdown). The dealership states that no recall appears under my VIN, but the safety failure is identical. The vehicle becomes unsafe and inoperable with no advance warning beyond the brief “Stop Safely Now” message. This defect poses a serious risk of a crash, injury, or death due to the sudden loss of propulsion in traffic.

CAR LOST POWER WHILE DRIVING-- IT OPERATED AT A LIMP AT FIRST-- JUST PRIOR TO THAT WENT FORWARD QUICK, THEN IT JUST STALLED WHILE DRIVING WHILE IN GEAR. THE GAS JUST MADE THE ENGINE REV. THE CAR THE NEXT DAY AFTER GETTING TOWED OPERATED AND THE SAME THING HAPPENED WHILE THE SERVICE STATION TOOK THE CAR FOR A TEST DRIVE. THEY HAD TO TOW IT BACK. THIS SAME PROBLEM WAS FIXED UNDER WARRANTY (20,000 ON APPROX. 03/2008). IT HAPPENED AGAIN. FORD REFUSED TO AGREE THAT THERE IS SOMETHING WRONG WITH THE DESIGN ETC. IF THIS HAD HAPPENED ON THE HIGHWAY AT HIGHWAY SPEEDS THE RESULTS COULD HAVE BEEN TRAGIC. I THINK IT HAS SOMETHING TO DO WITH THE THROTTLE PROBLEM... THE CAR LIMPS JUST AS EVERYONE AS COMPLAINED ABOUT. I HAVE NO IDEA WHAT WAS ACTUALLY FIXED UNDER WARRANTY AS THE PARTS MEAN NOTHING. PISTONS, GASKETS, SENSOR TURBI, HUB PLATE ASY, SEALS, AND MANY OTHER PARTS. *TR

TL* THE CONTACT OWNS A 2007 MERCURY MARINER. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE VEHICLE MADE A LOUD NOISE AND A CLOUD OF SMOKE CAME FROM UNDER THE HOOD. THE CONTACT WAS ABLE TO COAST OFF THE HIGHWAY. THE VEHICLE WAS TOWED TO THE DEALER AND THE CONTACT WAS ADVISED THAT THE OIL LIGHT ONLY ILLUMINATED AFTER THE ENGINE FAILURE. THE VEHICLE WAS REPAIRED AT A REDUCED RATE. THE CONTACT COULD NOT CONFIRM THE EXACT REPAIR THAT WAS MADE TO THE VEHICLE. THE FAILURE AND THE CURRENT MILEAGES WERE 73,000 MILES. UPDATED 07/19/12 *BF UPDATED 07/31/12

I PURCHASED THE VEHICLE WITH 6,000 MILES ON IT. I KEPT UP MY NORMAL MAINTANCE ON THE VEHICLE AND REPLACED THINGS WHEN NEEDED. AT APPROXIMATELY 42,000 MY TRANSMISSION WOULD NO LONGER SHIFT THE GEARS. THE VEHICLE WAS BROUGHT TO WALLACE DEALERSHIP OF WHICH THEY KEPT MY VEHICLE FOR ALMOST 2 WEEKS. THEY EXPLAINED THEY DID AN OVERHAUL OF THE TRANSMISSION AND FIXED REPAIRS ON IT SO THAT THEIR WOULD BE NO FURTHER PROBLEMS WITH TRANSMISSION LATER ON DOWN THE ROAD. NOW AT 84,735 MILES LATER, I AM ONCE AGAIN HAVING TRANSMISSION PROBLEMS AND MY VEHICLE WILL NOT GO INTO GEAR. BECAUSE I AM OUT OF WARRANTY MY VEHICLE WILL SIT UNTIL I CAN MAKE THE REPAIRS AS A TRANSMISSION REPLACEMENT IS NOT A CHEAP EXPENSE. THIS IS A SERIOUS PROBLEM WITH IN THIS CAR AND DESERVES EXTREME PRIORITY OF INVESTIGATION ON A RECALL FOR THIS YEAR, MAKE, AND MODEL OF VEHILE. I AM RECEIVING NO HELP FROM THE FORD COMPANY AND I AM FINDING IT EXTREMELY DIFFICULT THAT THIS PROBLEM IN THIS VEHILCE HAS NOT BEEN RESOLVED OR DEALT WITH. I HAVE HAD A PRIVATE TRANSMISSION COMPANY EXAMINE MY VEHILCE (HAS NOT TOUCHED IT), OF WHICH THEY DISCOVERED, THE INTERNAL FILTER IS CLOGGING THE CVT (CONSTANT VELOCITY TRANSMISSION) FOR WHICH SOMETHING WILL CONTINIOUSLY BREAK IN THE FILTER OR WHERE THE FILTER IS HELD CAUSING THIS TO HAPPEN. I WAS ALSO ADVISED THERE WAS NOTHING I COULD HAVE DONE MAINTANCE WISE OR PERSONAL USE OF DRIVING THAT COULD HAVE CAUSED THIS TO HAPPEN. *TR

THE CAR JUST LOST POWER WHILE DRIVING. SURGED A BIT THEN WAS OPERATING AT REDUCED POWER LIKE IT WAS LIMPING EVENTUALLY IT JUST STALLED AND THE GAS WOULD JUST REV THE ENGINE. FORD FIXED THE CAR UNDER WARRANTY. IF THIS HAS HAPPENED AT HIGHWAY SPEEDS IN TRAFFIC IT WOULD HAVE CAUSED A SEVERE ACCIDENT AS CARS WOULD HAVE BEEN DODGING A STALLED CAR AT HIGHWAY SPEEDS-. *TR
