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.
NHTSA complaint #11701977 — an unverified report by a vehicle owner.
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.

AS I AM DRIVING DOWN THE ROAD, ON A CITY STREET. THE VEHICLE WILL JUST SHUT OFF, FOR NO APPARENT REASON. IT DOES THIS SEVERAL TIMES. EVERY TIME THE CAR IS BEEN DRIVEN IT WILL SHUT OFF SEVERAL TIMES AND ME AND MY FAMILY HAVE BEEN IN TRAFFIC WHEN THIS HAS OCCURRED. IT CONTINUES TO DO THIS AT ANY SPEED AND EVERY TIME THE CAR IS DRIVEN. CAN'T DRIVE THE CAR NOT EVEN A MILE BEFORE IT TOTALLY SHUTS OFF.

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 IN THE PREVIOUS CLAIM 13N03 AND THIS CASE SHOULD BE REOPENED, BASED ON THE FATALITY POSSIBILITY OF A THROTTLE BODY FAILURE WITH THE ORIGINAL PART THAT CAME WITH THE VEHICLE, WHICH WAS ALSO RE-CALIBRATED PER FORD'S RECALL IN 2014. THIS INCIDENT PROVES THAT FORD'S RE-CALIBRATION DID NOT PREVENT FAILURE OF THE THROTTLE BODY. ASKING FOR A RECALL FOR THE THROTTLE BODY FOR THE SIMILAR MAKES AND MODELS STILL IN CIRCULATION AS IT'S A SAFETY HAZARD AND ALSO REIMBURSEMENT FOR THIS SERVICE FOR VEHICLES THAT HAD IT COMPLETED.

THE CAR IS REVING HIGH AND ACCELERATING POORLY. THEN THE RED TRIANGLE LIGHT TELLING ME TO STOP SAFETY NOW COMES ON CAUSING ME TO PULL OVER AND SHUT CAR OFF. I TURN THE CAR BACK ON AND IT DRIVES BUT WITH SAME ISSUES. LOOK ON THE CARCOMPLAINT.COM WEBSITE FOR TSB-09-19-12 AND TSB-08-24-5 WHICH DETAIL WHAT MY CAR IS DOING AND MAKES IT APPEAR LIKE THERE IS A COOLING PUMP RECALL. FORD JUST TOLD ME THERE ARE NO RECALLS LISTED FOR MY VIN THOUGH. THE FREQUENCY OF WHICH THE RED TRIANGLE LIGHT COMES ON IS INCREASING THIS MONTH. IT WAS EVERY FEW MONTHS AND NOW IT IS WEEKLY-DAILY.

WHILE TRAVELING APPROXIMATELY 35 MPH, DRIVING IN A STRAIGHT LINE ON A CITY STREET IN TRAFFIC, THE ABS ABRUPTLY APPLIED THE BRAKES - HARD! THE ABS LIGHT CAME ON AND A "CHECK BRAKE SYSTEM" WARNING MESSAGE WAS DISPLAYED. ALSO, THE ELECTRICAL SYSTEM SHUT DOWN AND THE ENGINE LOST POWER. AFTER ABOUT 5 SECONDS, POWER WAS RESTORED AND VEHICLE WAS ABLE TO PROCEED. THIS OCCURRED APPROXIMATELY 8 TIMES OVER A TWO MILE DISTANCE. DURING THE LAST 4 TIMES, THE ENGINE DIED, LOST POWER COMPLETELY, AND NEEDED TO BE TURNED OFF AND RESTARTED TO CONTINUE. THIS FAILURE WAS A DANGEROUS SAFETY HAZARD. VEHICLE WAS TOWED TO ALBUQUERQUE LINCOLN VOLVO. THE PROBLEM WAS DIAGNOSED AS A FAILED ABS MODULE, 9L8Z. THE DEALER REPLACED THE ABS MODULE WITH A FAULTLY MODULE. A SECOND ABS MODULE WAS INSTALLED AND THE VEHICLE WAS DEEMED REPAIRED. THE DEALER DID NOT RETURN THE DEFECTIVE PART FOR ANALYSIS.

MY VEHICLE: 2006 MERCURY MARINER HYBRID SUV. PURCHASED NEW IN 2006. IN HOT WEATHER...VEHICLE ENGINE QUITS WHILE IN MOTION ON FREEWAY AT APPROXIMATELY 70 MPH (3 TIMES), AND CITY STREETS (3 TIMES). EXTREMELY DANGEROUS WHEN ENGINE QUITS WHILE DRIVING ON FREEWAY IN TRAFFIC. ALL YOU CAN DO (WHILE PRAYING!) IS COAST TO A STOP AND DO YOUR BEST TO PULL OFF ON TO SHOULDER OF ROAD WITHOUT CRASHING INTO OTHER VEHICLES. WE HAVE TRIED 3 TIMES TO GET FORD MOTOR TO REPAIR THIS PROBLEM...ALL TO NO AVAIL. THE LAST TIME WE HAD TO PAY APPROXIMATELY $1,500. HOWEVER, FORD MOTOR DID REIMBURSE US! BUT AT THE SAME TIME THEY CLAIMED THE PROBLEM WAS RESOLVED. NOT TRUE! ABOUT TWO YEARS LATER THE PROBLEM STARTED ALL OVER AGAIN. FOR10 YEARS WE HAVE BEEN DRIVING A DEFECTIVE VEHICLE THAT WAS--AT ALL TIMES--A DANGER TO OUR LIVES. FORD MOTOR SHOULD HAVE TAKEN THIS PROBLEM MUCH MORE SERIOUSLY AND EITHER REPLACED THE VEHICLE WITH A ANOTHER ONE, OR TRULY FIXED THE PROBLEM. I FEEL FORD MOTOR HAS LIABILITY IN THIS MATTER. THE LAST TIME THIS PROBLEM OCCURRED WAS JULY 16, 2017.
