Selected complaints filed with NHTSA by 2005 Ford Ranger owners, lightly cleaned up (personal details are redacted by NHTSA).
Engine stalled ostensibly for lack of fuel. First engine stall episode occurred while vehicle was turning leftward into driveway at about 2 MPH and at approx 5 degree angle of inclination. Vehicle was towed from where it came to rest to repair shop where diagnosis was fuel pump failure resulting in replacement of the fuel pump (Ford OEM part.) vehicle performed reliably thereafter for a period of approx 39 months without stalling. Second episode occurred after vehicle shut off and resting on flat driveway surface overnight. The following morning engine cranked but would not fire or start. Again towed to different repair shop where diagnosis was again fuel pump failure however upon attempt to restart following pump replacement, engine would not fire or start. …
I would be driving and all of a sudden the whole vehicle would just shut down. This happened 3 or 4 times just going at 25 to 35 MPH. At first, I thought it was a clogged fuel line since it would somehow reset itself after having it towed to my mechanic so I replaced the filter even though I could see nothing wrong. When it happened again on a backcountry road the mechanic said it was probably the fuel pump so I had the whole thing replaced. It happened one more time after that, I was pulling onto a major highway and had just gotten up to speed 55 MPH and there was a tractor-trailer behind me when all of a sudden again everything shut down. Luckily I had enough moment built up I was able to coast to the side of the road before getting hit by the tractor-trailer. I finally looked online and found that someone had mentioned the same problem it May be the inertia switch. …
Ford Ranger 2005 4 cylinder fuel cutoff safety switch cuts off without warning, first time in 2012 while out of state, traveling on the interstate at 70 MPH, tried to pull over, but not much of a road shoulder. I had it towed 11 miles to an unfamiliar garage that, replaced the switch for $360. In 2015 switch failed, towed to a local garage and repaired. I believe they reset the safety switch and charged $70 dollars. Researched the problem and discovered hundreds of complaints, found out the switch is probably defective and can be reset. I cannot start my vehicle more than three times without resetting the switch. The Ford dealer wanted to replace my fuel pump for $850. I doubt that is the proper fix. This situation is extremely aggravating and quite dangerous. I don't know why Ford is turning away from this problem other than the number of owners that have this problem. …
Purchase vehicle July 2005, vehicle never had a good pull to it and I thought it was the way the truck just pulled until May 2006 when I was hit from behind by a Ford explorer, my truck got worse. In June 2007 engine light came on wouldn't go off. Gas cap light came on wouldn't go off. Tried to tighten cap, lights still haven't went off. Took truck to mechanic found out that my truck had a cracked head that was indicated that it could have been a defect from the manufacture and or possibly due to collision also Ford manufacture had a defect call back on all 2005 Ford Ranger. In December 2005 five month after I purchase the truck and they ( Ford) did not even notify me of the defect. I do have a copy in my possession from my mechanic. Also I was told that my truck could ignite and catch a fire at any time. Updated 01/11/08. There was a cracked head on the fuel sending unit. Updated

Fuel inertia switch malfunction, switch shorted out and caught fire. The inertia switch would trigger and shut off the fuel supply to the truck, this happened about 25times since purchasing the vehicle new, the last time it happened I was sitting still in bumper to bumper traffic and it just shut off. I reached under the passenger side of the dash board to reset it and could feel the heat from the electrical fire. I quickly shut off the vehicle and the fire died out. The safety switch is totally fried.
The fuel inertia switch would malfunction for no reason. The car would just die, losing all power (many times happening at 65 MPH on freeway). It happened at least 15 different times. The "reset" button would have to be used to get vehicle started again. Eventually, the component "melted," and had to be replaced. I was told at the dealership not to let the fuel level get lower than 1/4 tank, to prevent this from happening again. Very dangerous issue, which Ford is aware of< but does nothing!
Dt*: the contact stated while stopped at an intersection, the vehicle stalled and an odor of smoke was detected. The contact looked in the rear view mirror and noticed flames. A passerby extinguished the fire. The vehicle was towed to the dealership who determined the chemicals being hauled caused corrosion to the fuel tank, causing the fire. The vehicle was taken to an independent repair shop who determined the fire was a result of the design of the fuel tank.
The gas accident cut off switch cut out randomly during driving on a smooth flat road at highway speed as well as around town at slower speed. A less experienced driver could have had a deadly. Accident. I reset it several times and had to replace it. Ford should have had a re-call on this very dangerous problem. I have the old switch if it is needed.

'09 the ficos tripped while on a two lane road at 40mph causing the necessity to coast to the side of the road but not off the road, on a blind corner. During the dec. '08 and jan.
