NHTSA Complaint #10275214 — 2003 MERCURY MOUNTAINEER

2003 MERCURY MOUNTAINEER 4.6L-V8: WHEN THE VEHICLE IS NOT UNDER ACCELERATION [STOP SIGN/SIGNAL, EXITING AN EXPRESSWAY TO A SURFACE STREET, COASTING] THE ENGINE WILL NOT HOLD IDLE, THEN STALL. THE STEERING & BRAKES ARE COMPROMISED WHEN THE ENGINE STALLS. TO RESTART THE ENGINE, THE HEADLIGHTS GO DARK FOR A MOMENT...THIS IS A VERY SERIOUS MATTER. DECELERATING FROM AN EXPRESSWAY TO A SURFACE STREET, ON A CURVED EXIT RAMP , AT NIGHT MAKES FOR AN OUT OF CONTROL SITUATION WHERE THE DRIVER CAN NOT SEE BECAUSE OF ENGINE FAILURE! I'VE REPLACED THE THROTTLE POSITION CENSOR [TPS] WITH NO IMPROVEMENT. THE DEALER OFFERS REPLACEMENT OF PARTS $1500, AND NO GUARANTEE OF SOLVING THE PROBLEM. THE VEHICLE IS USELESS TO ME FORE IT IS A HAZARD TO BE ON THE ROAD...FOR ME AND ANYONE ELSE DRIVING NEAR ME. *TR
