2005 Ford Ranger engine problems

Filed Dec 10, 2021 · Acceleration, Brakes · WA

Incident was reported to me by an employee. Driving in traffic on a highway with normal, dry road conditions the accelerator pedal started moving down on its own. The truck accelerated on its own from 50 mph to 70+ mph. Applying the brakes the truck did NOT slow down. Eventually, the accelerator pedal corrected itself and started working normally. There was no indication on the dashboard of the issue. This could have resulted in a serious accident or death. The truck is waiting to be towed to the Ford garage for repair. Thank you, Wendy McNeill

At startup my check engine light came on and as I went to drive away the entire truck started shaking and the check engine light started to flash.I tried to fix the vehicle with a scan tool and started replacing the less expensive parts and when it was all said and done it turned out to be the driver side cylinder head number four and six cylinder they both had recessed valves.before the truck got real bad I was on the interstate going to be a slight incline and the truck was doing 75 miles an hour and then suddenly dropped to maybe 15 20 miles an hour almost causing an accident on interstate 10 I had to immediately pull off the shoulder of the road to avoid getting rear ended.I just recently replaced the third set of heads on the same vehicle same side same cylinders and I'm being told now that they think its the catalytic converters I really don't know I like my truck but this is getting ridiculous.I've called ford directly told them what's been going on and they said my truck does not fall under the campaign bulletins and that I will have to replace my head's every 42000 miles.

Engine begins to run very rough. Took to mechanic and was told my 3.0 v6 is suffering from well know (2004 - 2006) cylinder head failure - valve recession. New heads are needed to fix the problem. Cost of repair is approx, $2800. Head / valve failure / poor design of head is apparently well known by ford. Fuel leakage into the failed cylinder or cylinders could be a fire hazard if not repaired and driven continuously.

Loud squeal for several days thought it was tension pulley. That was replaced with no change. A few days later going down the road. A very loud squeal from the engine area and smell of burning rubber. Later was determined the vibration dampener had come apart. The rubber had come part allowing the groove section the belt rides on to slip toward the back up against the front cover. In looking online for information it was discovered this is a common problem with explorer and rangers with the 4.0 engine. A lot occur with low miles on the vehicle and some result it major repairs as the pulley flies off taking out the radiator. I was able to replace mine because I am a mechanic and have the tools to do the job. So my repair bill was not as much as others had stated.

While driving down the highway, the harmonic balancer failed. The pulley separated from the rest of the balancer and slid back to destroy the crankshaft position sensor. Once the sensor failed, the engine stalled. I was able to pull over to the side of the highway, but this sudden failure is dangerous and if I was not able to get to the side of the highway could cause an accident. After a little research on the internet there are several occurrences of the same issues on the ford 4.0 engine on ranger / explorer. Looking at the federal safety agency complaints sites there are also several occurrences of the same issue (more then 1 year, more then 1 model): odi id number : 10356858, odi id number : 10356913. Odi id number : 10450902, odi id number : 10383429, odi id number : 10243439, odi id number : 10168915, odi id number : 10351279, odi id number : 10390200, odi id number : 10302026, odi id number : 10279040. There may be more, but I was tired of looking.

I was coming down off 57 in rush traffic when the car died unexpectedly. Completely shut off, no warning, and would not start again. Several tries, more gas, more shut offs,screaming horns and I got it to the gas station off the highway. It went to garage. Its exhaust valve, wires and plugs were changed. Died on drive off the garage. Went in, had more repairs. Died in parking lot. Had computer diagnostics. 172 and 174 were diagnosed-failure of computer in exhaust system and mass air valve control. Basically, the exhaust system failed and shut off the engine. One of the heads is also suspicious.exhaust leaks are bad for the engine. All this, over $1,000 repairs, on top of transmission leak, two sets of brake pads and two sets of tires, in a truck between 39,000 - that is when it started- and 50,000 miles. In case you don't know this, right after the factory warranty expired, the truck fell apart. I found out that one person died of such failure in washington state and 2 were injured in oregon. All in ranger truck. Truck is well serviced, tires are not worn at all, have less than 12,000 and it is a killer truck. Ford is not responsive to the fact that their truck is a lemon. Their service center: I brought it to yorba linda ford dealer at 39,000 because the idle was rough, was told it was in my head and 12,000 later the idle is still dying, killing the engine.

2005 ford ranger with a 2.3 l engine. Changed oil at 33k and retrieved a valve keeper. Subsequent removal of overhead cams and timing chain assembly (5.8 hours of labor) and 500+ dollars out of my pocket revealed no valve keepers were missing. The dealership gave me a 1-800 number to ask questions.
