MERCURY Complaints

STALLING, TOTAL LOSS OF POWER ON FREEWAY, OR MAKING A CITY TURN, OR ACCELERATING FROM A STOP SIGN OR LIGHT, OR GOING UP EVEN A SLIGHT INCLINE, SUCH AS A DRIVEWAY TO A HOUSE. ONLY IN THE SUMMER. DO NOT DARE USE AIR CONDITIONING, WHICH MAKES IT OCCUR QUICKER AND MUCH MORE OFTEN. 95 DEGREES OUTSIDE, 113 DEGREES IN CAR - CANNOT AND DO NOT USE AIR CONDITIONER, BUT STILL HAPPENS ON TRIP OVER 15 MINUTES LONG. TOTALLY UNSAFE. LIKE OTHER CONTRIBUTORS, I WOULD LIKE TO KNOW WHY THERE HAS BEEN NO RECALL. JUST TODAY, JULY 10, 2013, 18-WHEELER BEHIND ME (CLOSE) ON 45 MPH CITY STREET, AND I STALLED. I STUCK MY LEFT HAND OUT OF MY WINDOW IN A "PLEASE STOP" GESTURE, AND DRIVER DID STOP, BUT I WAS TERRIFIED. MUST COME TO FULL STOP, PUT CAR IN PARK TO RE-START IT. BUT SAME THING WILL HAPPEN AT NEXT LIGHT OR SIGN OR CHANGE OF SPEED, WHETHER IN 5 MINUTES OR 30 SECONDS, CITY STREET OR FREEWAY. AT THIS POINT, I WOULD SAY THIS HAS HAPPENED APPROXIMATELY 250 TIMES. YES, THAT IS NOT A TYPO. NO QUESTION FORD KNOWS ABOUT THIS. *TR

THE SPEED CONTROL CABLE COLLAR BROKE, LEAVING THE THROTTLE STUCK OPEN AT ABOUT 27%. THIS CAUSED THE VEHICLE TO ACCELERATE ON IT'S OWN, AND REQUIRED EXTRA EFFORT TO STOP THE VEHICLE. I HAVE A RECEIPT FOR THE REPAIR MADE BY PEPBOYS. *TR

I'M 86 YRS OLD AND PURCHASED A 2010 MERCURY MILAN IN FEB.2013. THIS WAS A DEALER DEMO CAR WITH 13000 MILES ON IT. 2 MONTHS LATER SOMEONE WHO WAS FOLLOWING ME AT NIGHT PULLED ME OVER TO TELL ME MY BRAKE LIGHTS DIDN'T WORK. I DID SOME INVESTIGATIONS ON LINE AND FOUND OUT THAT MODEL OF CAR HAS MANY PROBLEMS WITH THE BRAKE LIGHTS NOT WORKING WHEN THE HEAD LIGHTS ARE ON. THEY WORK WHEN HEADLIGHTS ARE OFF. FORD WOULD NOT CORRECT THIS PROBLEM AND I HAD TO PAY $1000.00 FOR REPAIRS. AS I SEEN ONLINE IM NOT THE ONLY ONE WITH THIS PROBLEM, THERE ARE MANY OTHERS. I FEEL FORD IS WAITING FOR SOMEONE TO BE KILLED BEFORE THEY'LL DO ANYTHING ABOUT THIS PROBLEM! I WAS VERY FORTUNATE NOT TO BE HURT DO TO THEIR FAULTY EQUIPMENT. *TR

2009 MERCURY MARINER ENGINE STALLS, SURGES THEN NO ACCELERATION. COAST TO SIDE OF ROAD, WHILE TRYING TO NOT GET REAR-ENDED. ENGINE STILL RUNS, IS EXTREMELY ROUGH. AFTER TURNING THE IGNITION OFF, THEN WAIT AND RESTART, RUNS OKAY. THIS HAS HAPPENED ON MANY OCCASIONS IN PAST MONTH AND HALF. I CONTACTED FORD DEALER AND SERVICE GUY SAYS IT IS MOST LIKELY THE THROTTLE BODY STARTING @ $500 REPAIR NOT COVERED UNDER THE WARRANTY. HAPPENS AT ANY SPEED. FROM START OR JUST WHILE DRIVING. FIRST INCIDENT 5-31-2013. *TR

VEHICLE HEADLIGHTS WENT OUT AT HIGHWAY SPEEDS WITH NO APPARENT WARNING. PULLED OVER AND EXAMINED LIGHTS, ONLY FOG LIGHTS WORKING. TURNED OFF VEHICLE AND RESTARTED, LIGHTS WORKED. SPORADIC LIGHTS WORKING, THEN NOT WORKING. ABLE TO MANUALLY PULL AND HOLD DIMMER SWITCH TO ACTIVATE BRIGHT LIGHTS. AFTER RESEARCHING THIS PROBLEM ON THE INTERNET I HAVE DISCOVERED THE PROBLEM IS THE SAME ALL ACROSS THE COUNTRY IN THE 2003-05 MERCURY GRAND MARQUIS. THE LIGHTING CONTROL MODULE (LCM) IS PROBLEMATIC AND POSES A SAFETY CONCERN FOR MANY OWNERS. FORD CHARGES $700-800 TO REPLACE THIS MODULE WHEN I AND MANY OF THE INTERNET (HTTP://WWW.CARPROBLEMZOO.COM/MERCURY/GRANDMARQUIS/HEADLIGHT-SWITCH-PROBLEMS.PHP) OWNERS FEEL A RECALL IS A VALID REQUEST. *TR

HTTP://WWW.AUTOBLOG.COM/2013/02/25/NHTSA-INVESTIGATING-725K-FORD-MERCURY-VEHICLES-FOR-STALLING-ISS/ - READ COMMENTS ON THIS SITE. EXACTLY WHAT OUR MARINER IS DOING. 60 TO ZERO IN 2 SECONDS. YELLOW WRENCH LIGHT COMES ON, VEHICLE NO LONGER ACCELERATES, PULLOVER, TURN OFF, RESTART. HAS HAPPENED 3 TIMES. *TR

WHILE DRIVING AT 50-60 MPH THE CAR WOULD START TO SLOW AND THEN THERE WOULD BE NO THROTTLE RESPONSE, THIS HAPPENED 4 TIMES IN 40 MILES, AND LUCKILY I WAS ABLE TO PULL OF THE ROAD WITH NO PROBLEMS. AFTER THE CAR SAT FOR 5-10 MINUTES I WAS ABLE TO GET IT GOING AND THEN ABOUT 10 MILES LATER IT WOULD HAPPEN AGAIN. GOT IT TO A FORD DEALER AND FOUND OUT IT IS A BAD THROTTLE BODY. THIS PART IS ON NATIONAL BACK ORDER WITH NO IDEA WHEN AVAILABLE. HAD TO RENT A CAR TO GET HOME THAT DAY AT A COST OF $200. *TR

TL* THE CONTACT OWNS A 2007 MERCURY MARINER. THE CONTACT STATED THAT SHE STARTED THE IGNITION AND ATTEMPTED TO REVERSE FROM A RESIDENTIAL DRIVEWAY BUT THE VEHICLE WAS EXTREMELY SLUGGISH. THE CONTACT STATED THAT IT FELT AS IF THE VEHICLE HAD ENGAGED IN NEUTRAL. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 80,000. *TR

I WAS DRIVING TO WORK WITH THE CRUISE CONTROL SET AT 55MPH. THE CAR SUDDENLY LOST POWER AND THROTTLE RESPONSE. THERE WAS A WRENCH WARNING LIGHT LIT UP ON THE INSTRUMENT PANEL. HAD NO CHOICE BUT TO PULL THE CAR OVER TO THE SHOULDER. I TURNED OFF THE CAR AND RESTARTED IT. THE WRENCH LIGHT DISAPPEARED AND I HAD THROTTLE RESPONSE. I DROVE IT 3 MORE MILES DOWN THE HIGHWAY AND THE CAR DID IT AGAIN. I PULLED TO AN OFF RAMP AND TOOK THE CAR BY CITY STREETS BACK HOME. I LATER TOOK THE CAR TO MY FATHERS SHOP WHERE THEY HOOKED UP A HANDHELD 'SCANNER' TO IT AND WAS UNABLE TO PULL THE WRENCH LIGHT CODE. I TOOLED THE CAR BACK HOME AND PARKED IT AND STARTED DRIVING MY TRUCK. I HAD MY MECHANIC BUDDY BRING HIS MAC TOOL SCANNER TO MY HOUSE AND WE HOOKED IT TO THE CAR AND HE WAS UNABLE TO PULL THE CODE. SO WE DROVE THE CAR WITH THE SCANNER HOOKED UP AND WAITED FOR THE CAR TO ACT UP AGAIN. IT ACTED UP AGAIN ON THE HIGHWAY. WE PULLED OVER AND GOT A CODE SAYING THE "TAC IS STUCK OPEN". I BELIEVE IT TO BE A BAD THROTTLE BODY ASSEMBLY. I RESEARCHED THIS ON GOOGLE. *TR

COMMUTING HOME FROM WORK THE GAS PEDAL BECAME UNRESPONSIVE, THE ENTIRE BEGAN RUNNING VERY ROUGH, AND THE RED WRENCH SYMBOL ILLUMINATED ON MY DRIVERS DISPLAY. COASTED TO A SAFE SPOT TO PULL OFF, TURNED OFF THE CAR LET IT SIT FOR A MINUTE OR TWO, RESTARTED THE CAR, THE DISPLAY WAS CLEAR, GAS PEDAL RESPONSE WAS GOOD, AND ENGINE SOUNDED NORMAL. DROVE HOME WITHOUT FURTHER INCIDENT. FOUR DAYS LATER A SIMILAR INCIDENT, CONTACTED MY FORD GARAGE, DESCRIBED THE PROBLEM AND MADE AN APPOINTMENT FOR A DIAGNOSTIC. DIAGNOSTIC CAME BACK WITH THE THROTTLE BODY DIAGNOSIS, THE PARTS ARE ON BACK ORDER WITH NO ESTIMATED RECEIVING DATE. WILL COST JUST UNDER $500 TO REPAIR, 3 MONTHS OUT OF BUMPER TO BUMPER COVERAGE, JUST UNDER 27K ON THE CAR. NOT COVERED UNDER THE EXTENDED POWER TRAIN COVERAGE BECAUSE IT IS A SENSOR/ ELECTRICAL PROBLEM. I AM 7TH OR 8TH IN LINE FOR THE PART WHEN IT BECOMES AVAILABLE AT MY LOCAL DEALERSHIP. *TR
