While traveling at 48 MPH on 2 lane county rd I was in 4 wheel high when truck slammed into 1st gear causing truck to loose traction and ended up going into ditch. The truck never stalled out all gauges stopped working and tech light came on. I proceeded to be pulled from ditch. Then turned truck off .checked truck over it has body damage nothing visible under truck so I started it gauges where working tech light was off radio stopped working but could be loose connection I proceeded to limp it home at about 20 MPH was shifting hard at higher RPM I had it towed to body shop while at hospital.recall came on news I went to dealership they said bring it in they'll reprogram it . I'm wondering about damages caused by defect who will be paying for that? This defect is a danger and I can't believe it took ford 7 years from first report on here to address issue. And they claim only 5 cases of a crash which I have found 7 people who have had accidents because of it 4 of them where single vehicle 3 involved being rear ended because the sudden stop very disappointed in ford.

This truck is spontaneously shifting down to 1st gear. It is also getting stuck in different gears and not shifting properly, ford supposedly has a customer satisfaction program extending the warranty to 150,000 miles for the lead frame, however I took it to my local ford dealership and they do not want to honor the customer satisfaction program. I called ford corporate and the same thing. Not only when this problem happens does the transmission mess up but so does the instrument cluster, to the point where the speedometer doesn't work and the airbag light comes on.

Transmission shifts erratically, jumping from lower to higher gears. While up to speed, immediately shifts to 1st causing redlining of rpms. Speedometer jumps erratically. Happened initially while accelerating from a stop. Caused loss of power and feeling of misfiring, then sudden surge forward. After getting up to approx. 40 MPH, transmission shifts to 1st and stays there. Could have easily caused a crash if this happened while cruising at highway speeds.

I bought the truck in april or may. When my truck is stationary and turned off with the keys out of the ignition, my dash lights do not shut off. I didn't notice this the first time because, at night, my lights stay on for about 20-30 seconds and then shut off. The first time I noticed this, I got home for the night, put my truck in park, shut it off, and took out the keys. I used my remote to lock the truck. Got in it the next day and it was completely dead. I had to put it on the battery charger for about 30 minutes and finally got it started but I noticed while charging it (with the keys out of the ignition) that my dash lights were still on. Its almost like my truck does not know that it is in park and it thinks it is still in gear which keeps my dash lights on. A few days before I started experiencing this issue, my remote starter would not work all of the time. It was very hit or miss. I'm not sure what to do about this.

Vehicle has less than 45000 miles. Has erratic loss of power while accelerating. Evidence of water in the air intake. Research is showing that the ecoboost engine is collecting more water in the intercooler than the engine can consume. Problems increases in southern humid states. This is problem caused by faulty engineering in the 3.5l ecoboost engine and could cause accidents due to unpredictable loss in power. Loss of power is felt while driving on city and highway driving.

The vehicle would downshift into 1st gear without warning, has occurred when vehicle was traveling approximately 35 MPH. The vehicle would also remain in 1st gear after these incidents and intermittently when leaving from a stop, at an intersection. Vehicle has done this several times, in which case the dashboard displayed an illuminated malfunction indicator light and gone into limp mode, with only 5th gear available, while in an intersection. This problem would also cause the odometer to read '-------.--' and the speedometer to read '0 MPH', even when the vehicle is in motion, travelling at any speed. Vehicle is in otherwise perfect operating conditions. Diagnostic trouble code p0720 was displayed during these incidents. The manufacturer has customer satisfaction program 16n02 for 'certain' vehicles, in which the dealers are replace the molded lead frame within the transmission. In the case of my vehicle, this program did not apply to my vehicle, while at the same time, the molded lead frame within the transmission was determined to be the source of the issue and subsequently replaced. With my vehicle not applying for the noted customer satisfaction program, with the same faulty part as noted within the specific customer satisfaction program, it is my opinion that the affected vehicles with deficient molded lead frames is far greater than what was initially thought and therefore, the recall program should be extended to all f-150s and similar vehicles within the specified build dates, as noted within the customer satisfaction program. The molded lead frame failure should be considered a manufacturing defect and causes serious safety concerns for the drivers of those vehicles and to the travelling public.

The fuel pump relay and power fuses both melted which has caused starting issues and engine misfires. There are many reports of the same fuses melting in ages 2010 -2014 of the same ford f-150 trucks. This should be under a ford recall program as it caused trucks to loose power.

My f150 started to drop in to 1st gear unexpectedly when driving at at speeds greater than 50mph. At first the check engine light did not come on and mechanic could not find a source now I am getting engine codes p0720 and p0722.

Started my vehicle on a cold morning turned on the window defrost and rear defrost. Came back to it a few minutes later and the back window was smoking and the gasket had caught on fire. It shattered the window and burnt and melted the gasket. This seems to be a big problem with the f150 with rear defrost and power sliding window it either breaks the window or catches fire mine did not even blow the fuse. Have seen many cases of this thru f150 forums and ford has not come up with a solution. It is also a very expensive fix . My vehicle was stationary in my driveway had I not caught it in time this would have destroyed my truck and caught my house on fire too

I was driving on the highway. While accelerating the truck died. I had just enough momentum to get to the side of the road. Not knowing what happened I got my truck towed home. After researching all nigh, the next morning I pulled fuse #27 low and behold it was melted. I couldn't believe it, I felt very fortunate that it didn't cause an accident. I would like ford to right this common problem because of safety. I couldn't imagine how mad I'd be if my family were in the truck with me

Vehicle randomly shifts up and down. It will sometimes shift from 1st to 6th and then the vehicle does not go since it is in high gear. Other times, it will shift from 6th to 3rd. This happened while driving 70 MPH on expressway, it shifted to 3rd and caused the vehicle to jerk. I researched and others have had similar issues. Took to ford and they said it needs a new lead relay which will cost $600.
