2010 Mercury Mariner Hybrid engine problems

“Me and my wife purchased a vehicle from a private seller to use for personal commute. A month later we started to notice more issue were occurring with the car then stated from the seller. I took it to an auto body shop to get it inspected and possibly serviced and upon that inspection the clerk stated that there was a milage adjustment done to the vehicle. We contacted the seller to try and return the vehicle and receive our money back, but the dealer refused and requested us to resell it.”

“When the weather is hot (close to 100 degrees or more) and I am driving with the a/c - my vehicle on 3 occasions will not start after parking the vehicle and trying to restart it. The red padlock sign blinks and it won't start. At first it is trying to turnover but then will continually sound worse and all other warning lights go haywire. I leave the car alone for half a day and it starts up again like nothing happened. On the fourth occasion, the car stopped while driving, just a quiet shutdown and the car glided. This time it did not work for over 24 hours and then started up again like nothing happened. Multiple mechanics and also the dealership cannot figure out the problem because by the time i have it towed to shop, it works again. They did a full check on the car and cannot find anything wrong and there were no diagnostic codes. This issue happens when the weather is hot and poses a safety concern as now it is shutting off while driving and I become stranded each time. (First incident happened 8/25/18, last incident 5/14/22) Total of 4.”

“I was driving when it felt like the vehicle was reving in park then the "wrench" icon appeared on my dash. I went a couple blocks & my vehicle felt like it wasn't shifting automatically as it should. I pulled over & turned it off. It started right back up with no lights on, I went half a block & stopped at a stop sign but while stopped the engine reved up. I was worried I was going to be in an accident. Then the "wrench" light came back on, since I was close to home I figured I'd just try to get home. About another block, the check engine light came on & was making strange noises. I kept my vehicle at about 5-10 mph & got it home. My car was very jerky.”

“THE VEHICLE WAS IN MOTION AT A STOPLIGHT. THE LIGHT HAD TURNED GREEN, AND THE VEHICLE WAS BREAKING TO STOP BEHIND THE FIRST VEHICLE. I PRESSED THE GAS PEDAL TO FOLLOW THE FIRST VEHICLE AND THE CAR STALLED. THE CAR COULD NOT BE TURNED BACK ON OR PUT IN MOTION. THERE WAS NO INDICATION OF A PROBLEM PRIOR TO THIS THROTTLE BODY FAILURE. THE CAR WAS PUSHED OFF THE ROAD BY 3 PEOPLE AND INTO A NEARBY PARKING LOT. THE PROBLEM THAT MADE THE VEHICLE UNSAFE WAS A DEFECTIVE FORD THROTTLE BODY. THE REFERENCE CONSUMER SATISFACTION PROGRAM 13N03. I RECEIVED THE RECALL NOTICE JUNE 2014, BUT FORD ONLY SUGGESTED A RECALIBRATION (NOT REPLACEMENT). THE RECALIBRATION WAS COMPLETED AT FORD AUTONATION ON JUNE 23, 2014. FORD HAD ESTIMATED A THROTTLE BODY REDUCTION IN MOVABILITY AND NOT FAILURE. THE MILEAGE OF THIS MERCURY MARINER ON THE DATE OF REPAIR WAS 142551 AND THE IN-SERVICE DATE, 06/18/2010. THEREFORE, THE REIMBURSEMENT SHOULD BE COVERED UNDER FORD'S EXTENDED WARRANTY OF 150000 MILES/10 YEARS. THE REPAIR WAS COMPLETED 06/08/2020. TEN DAYS PRIOR TO THE EXPIRATION OF THE EXTENDED WARRANTY. FORD CLAIMS THEY WILL NOT REIMBURSE FOR THE THROTTLE BODY FAILURE. THIS WAS WELL-DOCUMENTED…”

“HAVING TWO ISSUES. THE FIRST ONE IS THE CHECK FUEL INTAKE WARNING LIGHT COMES ON AND MY CHECK ENGINE LIGHT STAYS ON. THIS APPEARS TO BE CAUSING MY CAR TO CUT OUT DANGEROUSLY AT INTERSECTIONS AS WELL AS THE WRENCH LIGHT TO COME IN AND MY CAR 'LIMPS' HOME.”

“CAR STOPPED RUNNING WRENCH LIGHT CAME ON STARTED MOTOR PUT IT IN GEAR TRIED TO GO REGULAR PACE CAR DID NOT GO IT IS VERY SLOW NO GAS PEDDLE TURNED IT OFF LET SET FOR 2 HRS. STARTED BACK UP RUNS OK BUT CHECK ENG. LITE CAME ON CALLED DEALER”
