2009 MERCURY MARINER Engine Problems

UPDATE TO 01/30/13 COMPLAINT. I PURCHASED CAR ON 10/22/12 WITH 58,398 MILES FROM A DEALER. I STARTED HAVING ISSUES LATE DECEMBER 2012. I WAS HAVING PROBLEM WITH CAR JERKING INTO GEAR OR BEING SLUGGISH WHEN ACCELERATING. I TOOK CAR TO DEALER ON 01/29/13. RESEARCHED CARFAX INFORMATION AND FOUND OUT THAT ON 01/05/10 - TRANSMISSION FLUSHED AND STATED AS REPLACED. 18,588 MILES. 08/09/10 - TRANSMISSION WAS REMOVED TO REPLACE COOLER. 28,372 MILES. ON 01/29/13 MECHANIC ADVISED THAT TRANSMISSION WAS LEAKING BADLY AND THAT "PRESS REGULATOR VALVE STICKING". 01/30/13 - TRANSMISSION VALVE BODY REPLACED. 63,356 MILES. 6 WEEKS AFTER VALVE BODY REPLACED CAR STARTED JERKING AGAIN. TOOK CAR TO DEALER ON 03/18/13...DEALER SUGGESTED REPLACEMENT OF TRANSMISSION, BUT EXTENDED WARRANTY COMPANY SAID NO...WOULD ONLY PAY FOR TRANSMISSION REBUILD. 65,951 MILES. THIS ENTAILED DAY AND HALF OF DEALER/WARRANTY COMPANY HAGGLING OVER REPAIRS. MECHANIC BEGAN WORK ON 03/21/13 AND FOUND LOTS OF MELTED PLASTIC THAT...

WHILE ENTERING INTERSTATE HIGHWAY, ENGINE BALKED LIKE BAD GAS. AFTER TWO OR THREE TANKFULS AND THE VEHICLE DYING IN TRAFFIC, I LEFT IT WITH MY DEALER TO FIND THE PROBLEM. AFTER A WEEK, THE VEHICLE HAD NOT DIED FOR THEM SO I BROUGHT IT HOME, ONLY TO CONTINUE WITH THE SAME DYING AND HESITATING WHEN ACCELERATED. A MONTH OR SO LATER THE DEALER KEPT IT AGAIN FOR ABOUT 5 DAYS AND IT STILL DID OKAY FOR THEM. THEY HAVE NO IDEA WHAT THE "PROBLEM" IS. WE HAVE PARKED THE CAR IN OUR GARAGE BECAUSE SEVERAL TIMES WE HAVE NARROWLY ESCAPED BEING REAR-ENDED, WHEN TURNING CORNERS, CROSSING RAILROAD TRACKS, ETC. I CONTACTED FORD MOTOR CO. IN MICHIGAN AND THEY DO NOT "HAVE THIS PROBLEM WITH OTHER VEHICLES" AND DON'T SEEM TO KNOW WHAT I'M TALKING ABOUT. MECHANICS IN TWO OTHER GARAGES HAVE DRIVEN THE VEHICLE AND HAVE NOT LOCATED THE PROBLEM....

AFTER COMING TO A STOP AT A LIGHT OR STOP SIGN, AS I ACCELERATE MY CAR JUMPS/JERKS AS IF IT'S STRAINING TO SWITCH TO NEXT GEAR. GENERALLY HAPPENS WHEN ACCELERATING BETWEEN 10-40 MILES. WHEN IT INITIALLY STARTED IT WOULD HAPPEN 1-2 TIMES A WEEK. NOW IT HAPPENS EVERY DAY. I HAVE AN APPOINTMENT SCHEDULE TO HAVE DEALER LOOK AT VEHICLE. *TR
