ENGINE
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.

HYBRID PROPULSION SYSTEM
The contact owns a 2007 Mercury Mariner. The contact stated while driving 50 MPH, the engine started to overheat, after which the vehicle lost motive power. The contact was able to pull to the shoulder of the roadway to let the engine cool down. After restarting the vehicle, the vehicle returned to normal functionality; however, the failure had since become a regular occurrence. The engine overheated warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 14V526000 (Hybrid Propulsion System) but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 247,000.

STRUCTURE:BODY, SUSPENSION
PASSENGER SIDE REAR INNER FENDER WELL RUSTED COMPLETELY THROUGH ABOVE THE REAR SHOCK CAUSING THE SHOCK TO POTENTIALLY BREAK THROUGH AND DROP THE WHOLE SUSPENSION AND CAUSE AND ACCIDENT OR FLIP OVER IF IT BROKE THROUGH DURING A TURN. THE REST OF THE VEHICLE HARDLY HAS ANY RUST ON IT. THE MARINER SHARES THE SAME INNER SHEET METAL AS THE FORD ESCAPE AND THERE HAVE BEEN MANY COMPLAINTS OF THIS HAPPENING TO ESCAPES. MY VEHICLE WAS STUDIED AT A FORD INVESTIGATION ABOUT 4 YEARS AGO FOR THIS PROBLEM. I WAS TOLD THEY WERE WORKING ON A SOLUTION AND NOTHING EVER HAPPENED. THE EMPLOYEE TOLD ME THAT THE UNDERCOATING THEY USED OF THESE YEARS OF ESCAPE/MARINERS WAS FAULTY AND BROKE DOWN PREMATURELY CAUSING THE INNER FENDER EXPOSED TO THE ELEMENTS. THIS IS ALSO HAPPENING ON THE DRIVER'S SIDE WHERE THE UNDERCOATING IS START TO BREAK DOWN. THIS IS NOT A CASE OF MISUSE BY THE OWNER BUT AN ACTUAL DESIGN FLAW AND A BIG SAFETY ISSUE AS THIS COULD CAUSE A LOT OF HARM. LUCKILY I HEARD THE LOUD KNOCKING FROM THE REAR END AND STOPPED DRIVING IT.

POWER TRAIN
I HAVE JUST FOUND OUT I HAVE LOST 2ND GEAR AND 4TH GEAR IS ON ITS WAY OUT ON MY CAR. APPARENTLY THIS IS A PROBLEM THAT FORD HAS KNOWN ABOUT AT LEAST SINCE 2012, ACCORDING TO AN ONLINE FORD MOTOR COMPANY PUBLICATION, MAYBE EVEN EARLIER. THE PUBLICATION STATES THAT IT AFFECTS 2007-2008 FORD ESCAPES AND MERCURY MARINERS. WHAT I WANT TO KNOW IS, IF THEY KNEW ABOUT IT AT LEAST FIVE YEARS AGO, WHY WASN'T THERE A RECALL AND IF NOT A RECALL, SOME KIND OF FINANCIAL ASSISTANCE/COMPENSATION FOR THE REPAIRS? I'VE SHOPPED AROUND FOR PRICES AND THE BEST I COULD FIND WAS $2200.00 FOR THE REPAIR PLUS ANOTHER $225.00 FOR A RENTAL TO USE WHILE MY CAR IS BEING REPAIRED. THE REPAIR IS GOING TO TAKE 3-5 DAYS.

SERVICE BRAKES
THE BRAKE SYSTEM'S HYDRAULIC CONTROL UNIT ("HCU"). ON SEVERAL OCCASIONS WHILE DRIVING, THE BRAKE PEDAL WILL TRAVEL TO THE FLOOR WHILE TRYING TO BRAKE RESULTING IN NO BRAKING ACTION (IE., VEHICLE NOT SLOWING). THIS MIGHT HAPPEN FOR ONE OR TWO PEDAL DEPRESSIONS BEFORE THERE IS ANY SLOWING OF THE VEHICLE. THIS PROBLEM HAS PLACED ME IN SITUATIONS WHERE I HAVE TO TAKE EVASIVE ACTION TO NOT HIT A VEHICLE IN FRONT OF ME, OR TRAVELING INTO A CONTROLLED (WITH STOP SIGNS) INTERSECTION. BELOW THERE IS A SPACE TO SPECIFY 'WHEN DID THIS HAPPEN.' I AM INPUTTING THE MOST RECENT DATE OF THIS PROBLEM, BUT IT HAS HAPPENED AT LEAST TEN TIMES BEFORE THIS.

STEERING
THE POWER STEERING WENT OUT IN MY MOTHER'S 2007 MARINER HYBRID WITH 72,000 MILES DUE TO FAILURE OF THE POWER STEERING CONTROL MODULE. AFTER SEARCHING ONLINE FORUMS, I FOUND THIS TO BE A RATHER COMMON ISSUE ON THE 05-07 MARINER AND ESCAPE HYBRIDS. THE REPAIR WILL COST JUST UNDER A THOUSAND DOLLARS ONCE YOU LOCATE THE PART. AFTER HAVING IT DIAGNOSED AT MY FORD DEALER, I CONTACTED FORD CUSTOMER CARE TO SEE IF THEY COULD RESOLVE THE ISSUE, AND THEY ACTED LIKE IT WAS SOMETHING THEY WERE UNAWARE OF EVEN THOUGH IT DOES NOT TAKE MUCH SEARCHING TO SEE IT'S A COMMON PROBLEM. ALSO IT'S A SAFETY ISSUE. THE SAME PART WAS RECALLED ON THE 08-11 ESCAPE AND MARINER HYBRIDS, AND THE RECALL SHOULD HAVE INCLUDED THE 05-07 AS WELL.
