The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015.

“TL* THE CONTACT OWNS A 2007 MERCURY MARINER. WHILE THE CONTACT'S SON WAS DRIVING THE VEHICLE, THE TRANSMISSION SLIPPED AND WENT INTO OTHER GEARS. WHEN THE VEHICLE WAS IN NEUTRAL, IT SHIFTED INTO DRIVE ON ITS OWN. ON ANOTHER OCCASION, THE CONTACT'S SON STATED THAT THE VEHICLE FELT AS IF IT WERE DRAGGING AFTER IT JUMPED. IN ADDITION, "OVERDRIVE" APPEARED ON THE CONTROL PANEL THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC, BUT WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE WAS THEN TOWED TO ANOTHER INDEPENDENT MECHANIC WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT TO CALL NHTSA. THE DEALER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 152,000.”

Engine

7 reports
“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…”
