While in motion, several items occur. It begins with following warning lights: "park brake limited function" and the "hill start assist not available". this has resulted in the cruise control not working, sudden deceleration, engine stalling, and transmission erratically shifting. This has occurred over twenty four times at highway speeds and on city streets. The vehicle has been in the shop at the dealer five times and the problem is getting worse.

All 4 doors have malfunctioned. They do not latch, or stay closed. This has happened while in motion and stationary. Turning, the door has opened and the back doors have frozen and not latched. I have video but they are too large to attach. This truck has been at the dealership 5 times for the same repair, and to date they've had it for 23 day.

I have noticed my tailgate randomly down but never thought much about it. Wednesday the 11th of December 2019 I was towing a car hauler trailer. I drove to my location and made a turn and heard a crunching noise. It turns out the tailgate was down and in a turn it got crunched by the trailer jack. I took it to my Ford dealer to have it looked at. It is scheduled for Dec 26th. Tailgate will need to be replaced. Tailgate will need to be replaced.

The transmission will twist the driveshaft at startup, stationary, and cause the rear end to pop very loudly. I've shown Ford engineering a video of it, I was told that it was normal. I've never heard of a vehicle doing this before. There is a rattling sound on deceleration, loudest when the engine is cold and lessons or maybe even goes away after warmed up. The engine was replaced earlier this year because of an oil consumption issue. The truck has memory power driver's seat and power mirrors that should go into place depending on the key fob that it detects. Randomly both side mirrors will start moving and popping before going back into position. This always occurs before the vehicle is started. I've noticed that it is usually when it detects the key fob or when I use the fob for some function. The seat randomly doesn't go into the memory position at startup.

Started to pull through a residential intersection after stopping at a stop sign. The truck completely shut off after moving about 5 feet pulling into the intersection. A message popped up on the dash screen about auto startstop and that I needed to put the truck in park and restart it. This is not something that can be done while the vehicle is in motion. I slowly rolled to the side of the street, put it in park and restarted. There were no more issues on the remaining 25 mile drive. The autostop feature had been disabled via the dash switch before ever leaving home. The switch was still illuminated amber showing that autostop had in fact been turned off manually before it happened on its own, while under power. With the engine not running, the power steering is also disabled. After a bit of investigation, I have found via online truck dedicated forums that I am not alone and this has happened to numerous people with F150's since 2015. The picture that I am attaching is not my own, but is the same message that was generated to me this morning. This picture is from another individual that this has also happened to and reported in the above mentioned forums. Autostop initiation of its own Accord while underway could have dire consequences if pulling into oncoming traffic, through a busy intersection or simply driving down the road.

I have had issues with errors/failed sensors for the tire pressure monitoring system on this vehicle. After 2 trips to the dealership and changing 2 sensors the issue was still present. I accidentally identified the source of the issue - interference from a dashcam - a rexing V1P pro 3rd generation. Measured on a spectrum analyzer this interference is at 312 mhz at around (-78 dbm 1 M from the dashcam) while the TPMS sensors operate around 315 mhz and measure around -82 dbm at the same location. This level of interference (even if it is in excess of fcc part 15 emissions - and I will be checking with the fcc also) at this kind of frequency separation should not cause errors or a failure in the TPMS monitoring system. Also of concern is that the errors do no show up for 45 min-1 hr of driving despite TPMS data from one or more wheel not being received for this duration (confirmed through odbii data). This all points to a poorly/cheaply designed TPMS receiver module that is prone to failure if exposed to rf from any number of devices. I am also an amateur radio operator and do 2-way radio work for the federal government so it concerns me that even normal lmr operation in one of these vehicles could cause a safety issue. The TPMS receiver should be tested for reasonable reliability in the presence of rf in adjacent spectrum and recalled if not compliant with fcc part 15 or NHTSA operational requirements. The dealer/manufacturer have refused to even look into this issue beyond what they have already done at the dealership.

Tailgate randomly opens while driving and or after driving when parked. Will also happen again repeatedly after closing. While tailgate is open after falling in open position you can hear relay clicking noises in passenger side dashboard area. Sounds like relays are constantly triggering to open tailgate. Initially thought key fob was triggering problem, but isolated keyfob and determined keyfob is not the issue. Am concerned that items in back of bed area are going to fall out when truck is moving and cause accident or worse. Sometimes do not hear that the tailgate opened when driving. My vehicle has factory installed bed cover and cannot see if tailgate is down from inside of vehicle

Ford 2018 F150 rear window / defroster issues - luckily, my rear window did not shatter as others have experienced, but I have experienced defroster overheating to the point where 2 out of 3 sections of the window no longer work. Upon inspection, it appears the resistive elements are burnt and becoming delaminated from the window in multiple places. I did also smell warm/burning electronics at the time it happened. I took the truck to the dealership - as this should still be under warranty, but was told the claim was denied, even though I did nothing to cause this and they could not tell me what happened. I can see how a sudden over-current / overheating like this could lead to glass shattering and Ford should be held liable if their controls and/or defroster are not working properly. It is also dangerous, as my vision is obstructed as a result of this issue. This most likely happened when the vehicle was stationary, during warm-up, using auto-start.

We got into an accident over the weekend. We were T-bones by a bus. It wrecked the passenger side of the car. However, when I went into the passenger side to get my purse out I noticed that there were flames coming from the side of the drivers seat. Our F150 is now burnt to a crisp. There's no reason for that truck to have caught fire like that.

Truck shuts off when pulling a camper and will not run after restart unless you rev the engine and quickly pull the shifter into drive and accelerate quickly. The instrument panel shows 'auto startstop shift to P, them restart engine.' This has caused many near miss accidents. The vehicle will stall when you try to cross an intersection or pull away from a stop sign.
