WHEN MAKING A SUDDEN STOP, THE BRAKE PEDAL GOES TO THE FLOOR WHILE MAINTAINING PRESSURE ON THE BRAKE PEDAL. WHEN HOLDING VEHICLE ON A STEEP INCLINE (STOPPED), THE PEDAL GOES TO THE FLOOR. HAD IT BACK TO FORD DEALERS AND WAS TOLD THIS IS A NORMAL CONDITION FOR EXPLORERS AND MOUNTAINEERS EVEN THOUGH SERVICE MANAGERS AND THE MECHANICS HAVE TOLD ME THERE WAS A PROBLEM WHEN THEY INITIALLY CHECKED THE BRAKES.

APPARENTLY THERE HAVE BEEN A LOT OF ISSUES WITH THE THERMOSTAT HOUSING LEAKING FLUID INTO THE ELECTRICAL SYSTEM CAUSING IT TO SHORT OUT. I WAS DRIVING, WENT TO TAKE OFF IN RUSH HOUR TRAFFIC AND THEY VEHICLE WOULDN'T GO BECAUSE THE LEAK AND RUINED A PART OF THE ELECTRICAL SYSTEM AND THE GEARS WOULD SHIFT. IT WAS ALMOST LIKE THE TRANSMISSION HAD GONE OUT. I HAVE READ SEVERAL ACCOUNTS WHERE THIS HAS HAPPENED TO TONS OF <09 MOUNTAINEERS AND EXPLORERS. TSB 09-22-15 CAME OUT ABOUT THIS ISSUE. I WAS DRIVING WITH MY INFANT DAUGHTER AND WE COULD HA…

MY 2007 MERCURY MOUNTAINEER NEVER HAD ANY PROBLEMS UNTIL RECENTLY, THOUGHT IT WAS THE TRANSMISSION BECAUSE OF THE WAY IT DROVE. TOOK IT TO THE MECHANIC AND GOT TRANSMISSION FLUID PUT IN BUT THE PROBLEMS REMAINED THE SAME AND WAS TOLD THE TRANSMISSION WAS FINE. MY THERMOSTAT HOUSING UNIT WAS LEAKING (THIS IS VERY COMMON WITH THESE CARS AND VERY DANGEROUS, NEEDS IMMEDIATE ATTENTION!) AND HAD CAUSED VERY EXPENSIVE WIRING ISSUES. ALMOST ACTS EXACTLY LIKE THE TRANSMISSION IS GOING OUT - RPM'S ARE WAY TOO HIGH, THE VEHICLE WOULD NOT ACCELERATE IN THE…

I WAS DRIVING ON THE HIGHWAY AND NOTICED THAT MY STEERING WAS NOT WORKING WELL. MY ENGINE WAS OVERHEATING AND EVENTUALLY SHUT OFF. I HAD TO PULL OVER ON THE SIDE OF THE HIGHWAY. WHEN I GOT SOMEONE TO LOOK AT THE CAR, WE REALIZED IT HAD NO COOLANT. WE FILLED UP THE COOLANT AND EVERYTHING SEEMED FINE. ABOUT A MONTH LATER I NOTICED THAT THE ENGINE WAS MAKING THE SAME NOISE AS IT HAD BEFORE AS IF IT WERE WORKING TOO HARD. I CHECKED THE COOLANT AND IT WAS COMPLETELY EMPTY AGAIN. I HAVE A FRIEND WHO ALSO OWNS THE MM AND HAD THE SAME PROBLEM. THE REPA…

FIRST OFF WHEN I BOUGHT THE VEHICLE THE REAR WIPER DOES NOT WORK. SECONDLY WHEN YOU PUT THE VEHICLE IN REVERSE IT JOLTS BEFORE GOING INTO REVERSE. FINALLY IT ONLY LET'S YOU PUT SO MUCH OF FUEL INTO THE GAS TANK AT A TIME BEFORE STOPPING THE FUEL FLOW INTO THE GAS TANK. *JS

I was driving on the expressway and my truck just shut off. The car panel Illuminati to a check engine light and a wrench. I had to put on my caution light and make it to the shoulder. That was scary. I sat for 10 minutes before it started back up. I've taken it to the dealership and all they did was guess what the problem could be. They said it might be the fuel pump or something electric or the computer. That's not doing me any good, because I'm still having this problem.
