Secondary timing chain link came apart soon after i bought the truck in 2015 at 66,000 miles my warranty paid for it. now it is happening again but on the other side of the engine. 2 time chain links fall apart. ford is not paying for this because my warranty was up 2 months ago and it is not a pre certified truck, miles are 120,066 miles. 2 timing chain links break in 4 years???????? the technicians at santa maria ford said they have never seen anything like this before. ford is denying to pay for this repair!!!!!!!

I am the third owner of this vehicle. we purchased vehicle with around 114,000 miles. within a week and a half, the engine started knocking while driving/engine running. upon further review, the engine needed replaced. due to the fact we do not know previous owner(s), unsure if it was a maintenance issue or a manufacturer issues. mechanic could not be definitive.

On at least 6 occasions, truck misfires and shakes violently when under load or attempting to accelerate. pull off road or let off of accelerator and engine resumes normal operation. happened once pulling empty trailer, happened 4 times merging onto interstate. happened multiple times passing / accelerating on interstate. frightening and dangerous when truck shakes violently on interstate. roads were wet or rainy conditions in last 5 incidents. 2012 f150 fx4 with only 87000 miles. no accidents. truck maintained and in excellent condition.

While driving at 60mph the transmission shifted into first without warning, causing a sudden loss of control of the vehicle almost causing multiple accidents as i was in the middle of rush hour traffic. the sudden down shift over spun the motor, resulting in a lower engine knock which a certified ford technician believes is the result of a bearing failure. even though the technician performed a cylinder leakage test in which no indication of valve interference was identified, the ford engineer he was dealing with said he had seen this issue before! this is the same recall issue that has caused multiple accidents! there are dozens of blog posts where this issue has caused, at the very least, multiple trips to the dealerships and in rare cases (not including mine), engine failure. i have calculated the engines rpm's using the formula: axle ratio x vehicle speed x transmission ratio x 336.13) / tire diameter = engine speed. at the time of the incident, the engine's rpm's were at an estimated 9,074 rpm's [(3.55 x 60mph x 4.17 x 336.13)/32.9]. the tachometer only goes to 7,000 rpm's! there are ...

I was driving on sr 71 north of columbus ohio in the rain when i changed lanes and tried to accelerate but the engine just started shaking and my engine light started flashing. the truck would not accelerate and started to slow down. i managed to get out of traffic and got off the highway. after sitting a few minutes i tried to get back on the highway. when i tried to accelerate the truck started shaking and would not accelerate. after a 3rd attempt the truck finally got up to speed and i made it home. my engine light is still on. i began to read forums on the ford f150 fx4 and discovered many many people are having this problem with moisture and the intercooler system.. i could've died today. this needs to be made right by ford motor company.

Engine kills won't start due to fuse #27 blown

Truck currently has a recall on it due to it going into first gear unexpectedly. took truck to closest dealership two weeks ago and had the recall service completed. was told to expect my check engine light to be on for three or four days. when it stayed on a week i called them back to discuss the light still being on. rescheduled a follow up appointment for april 12. on april 5 and april 7 the truck had the same problem that the recall was supposed to fix. going approx 50mph when the truck went into first gear with wheel hop and some fish tailing. when this problem occurs the instrument panel will basically go to all zero's and it takes the truck being turned off for the computer to reset and allow truck to drive normally. just wanted to document here since truck goes back to dealership tomorrow.

Driving vehicle at approx 65mph, engine lost power, engine wrench light, illuminated, oil pressure light illuminated, engine shifted to 'limp mode'. no acceleration. pulled over to the side of the highway. waited 2 minutes and restarted the engine. was able to get home. took to certified ford dealership for repair. issue occurred twice more while driving to the dealership for repair. needed to replace the throttle body.
