2007 MERCURY MILAN PREMIER BEGAN RUNNING VERY ROUGH WHILE TRAVELING DOWN A BUSY COUNTY ROAD. THE ROUGHNESS APPEARED TO INCREASE WHEN THE ENGINE WAS UNDER LOAD. I CALLED MY MECHANIC AND WAS INSTRUCTED TO BRING THE CAR BY FOR A COMPUTER ANALYSIS. APPROACHING THE SHOP, NO MORE THAN 4 MILES SINCE ONSET OF PROBLEM, I BEGAN TO SMELL A STRONG ELECTRICAL BURNING. UPON LIFTING THE CAR'S HOOD THE ELECTRICAL BURNING SMELL WAS OVERWHELMING AND SMOKE WAS STREAMING FROM THE #4 CYLINDER IGNITION COIL. CAREFULLY REMOVING THE COIL REVEALED FEET UPON FEET OF UNRAVELING AND BURNING COIL WIRE, ALONG WITH RUBBER FROM THE COILS SPARK PLUG BOOT SMOLDERING AND DRIPPING MOLTEN RUBBER DOWN THE HOLE... THIS COULD HAVE TURNED OUT TO BE A VERY DANGEROUS CONDITION... IF THE CAR HAD BEEN DRIVEN ANY FURTHER, I TRULY BELIEVE AN OPEN FLAME WOULD HAVE BROKEN OUT... I WAS RELIEVED THAT MY WIFE OR CHILDREN WEREN'T DRIVING THE CAR AT THE TIME.. MY MECHANIC SAYS THE PCM COMPUTER POSSIBLY SHORTED OUT AND MAY HAVE DAMAGED THE OTHER COILS AS WELL. THE CAR WILL NOW HAVE TO BE TOWED TO A MERCURY DEALER FOR A VERY EXPENSIVE REPAIR.. I WAS TOLD THERE IS NO RECALL FOR THIS VERY DANGEROUS CONDITION ON A MERCURY MILAN, HOWEVER IT'S SISTER MODEL, A FORD FUSION, DOES HAVE A RECALL. THIS LEAVES ME VERY FRUSTRATED AND MOST LIKELY BROKE... *TR
