NHTSA Complaint #10505649 — 2010 MERCURY MARINER

SEVERAL TIMES, WHILE DRIVING VEHICLE, ENGINE SUDDENLY LOST POWER AND THE CHECK ENGINE LIGHT CAME ON SOON AFTERWARD. AT TIMES I WAS DRIVING AT HIGHWAY SPEEDS, AND AT TIMES SLOWER--THE LAST TIME BEFORE SERVICE WAS APPROX. 40 MPH. HAD TO PULL OVER SEVERAL TIMES TO THE SIDE OF THE ROAD, STOP THE ENGINE, THEN RESTART AND TRY TO CONTINUE DRIVING. AFTER SEVERAL MORE LOSSES OF COMPRESSION AND POWER, RETURNED HOME AND TOOK THE VEHICLE IN FOR SERVICE TO THE DEALERSHIP WHERE IT WAS PURCHASED. THEY RAN DIAGNOSTICS, BUT WERE UNABLE TO DUPLICATE THE PROBLEM. PROBLEM RECURRED SEVERAL TIMES AFTERWARD, AND WITH THE CHECK ENGINE LIGHT STILL ON, RETURNED FOR SERVICE ON 4/02/12, WHERE THE DIAGNOSTICS CONFIRMED A PROBLEM WITH THE THROTTLE BODY. IT WAS REPLACED AND THERE HAVE BEEN NO PROBLEMS SINCE THEN. I HAD TO SPEND THE FOLLOWING AMOUNTS FOR SERVICE: DIAGNOSTICS ON 3/30/12: $59. ACTUAL REPAIR ON 4/02/12: $450.61. *TR
