This is a serious safety hazard that could result in death or injury. If I hadn’t escaped in time, I would have been killed. I am urging the NHTSA to investigate this defect and take immediate action to remove these vehicles from the road. Others may not be as lucky. This issue is life-threatening, especially because the fire started while the vehicle was in motion. These vehicles must be recalled and removed from use before more people are injured or killed.

I started Mercury with foot on break like normal. Shifted into reverse. Car accelerated backwards at full speed. Brakes did not stop car. Attempted to shift into neutral but went into drive instead. Car accelerated forward at full speed with my foot still on break. Car hit metal post and tree knocking them down and dragging the tree 50 to 60 feet before stopping with my foot still on the break. Car had stopped accelerating. I turned off the ignition. This unintended acceleration had happened before. Two different dealers attempted to fix the problem. Both of them thought they had been successful but it happened again. Previously, applying the brakes stopped the car, but not this time. Someone could have been injured severely or killed.

When driving the steering will feel loose and the car sway left and right but the steering wheel isn't moving. Feels like the front wheels are going to all of a sudden shoot left or right and loose control.. I had a 2001 crown Victoria and there was a recall on the steering shaft and I got that fixed. it was doing the exact thing my mercury is doing now.. and also my electrical is freaking out.. turn signals flash very fast here and there.. speedometer will freak out and then not work.... I'm mostly concerned about the steering because it happened in my crown victoria.
NHTSA complaint #11495888 — an unverified report by a vehicle owner.
?yrs.ago While backing out of parking space at Calaveras Lumber, after shifting into reverse, & removing my foot from the brake; the engine appeared to receive a huge burst of fuel which shot me backward like a rocket slamming my vehicle into and wedging it under the frame of a pickup truck parked in the same lot. I am glad I was parked and had my foot on the brake prior to this unit or system malfunction otherwise the injuries could easily have been fatal on the highway. I think this defect may be a contributing factor to the car dying recently while on my way to a Wedding Reception in Roseville, which left me stranded after dark for 41/2hrs and 71/2hrs. 2days later. I have not been able to start vehicle since and mechanics unable to diagnose why the engine is fuel starved when system parts tested appear to be in good working order. Something seems to be shutting off power or preventing power to the fuel pump and it is not the inertia switch, relays, fuses etc.. Components have been previously inspected by numerous others including dealer. No Recognizable Alert/Warning Prior to Incidents!
NHTSA complaint #11474583 — an unverified report by a vehicle owner.
First issue: The headlights and door chime stay on after key is removed and lights are off causing battery to drain while vehicle is not being operated. Second issue: 50 amp ignition fuse blows randomly while car is in motion which causes a complete loss of power to the car including: braking power and power steering assist. The tilt steering being raised or lowered fixes the problem temporairly on occasion. A clicking sound from the lighting control module is heard when adjusting the tilt steering also

Catalytic converter FAIL, engine idles rough while in park. HIGH Loss of engine power while driving Differentials in back tires are imbalanced…timing FAIL. Steering not calibrated, drivetrain out of sync altogether. Back wheels, left and right; randomly spin & torque hard while car is already in motion on any private road, hidden road, domestic road and high capacity, high speed highway, causing vehicle to fishtail uncontrollably and dangerously, and wildly side to side potentially veering off the road which could result in death unless the driver regains proper control of vehicle. Out of sync car computer and the mechanical devices built into car do not have proper timing performed on those particular moving parts altogether. The car was not manufactured properly mechanically nor electrically altogether. Headlights & electric system etc have an incomplete recall on my vehicle.

SOMETIMES THE HEADLIGHTS FLICK ON AND OFF WHILE DRIVING. THEN WHEN THE CAR IS TURNED OFF, THERE IS A CLICKING NOISE IN THE DRIVER SIDE DASHBOARD THAT CONTINUES UNTIL IT DRAINS THE BATTERY. ALSO, SOMETIMES THE DOOR LOCKS CYCLE OPEN OR CLOSED WHETHER THE CAR IS DRIVING OR OFF.
