Vehicle in 4 wheel hi mode has a tendency to bind up in reverse at low speed. sometimes affects the forward motion. can count on 1 hand the amount of times this has been engaged.

The truck was running for about 15 minutes. we were going down a major highway in one of the passing lanes at approximately 70mph then without any warning power was lost. on the display trac stability came on then cycled thru hill assist and several others. i drifted of the road just past a exit. the engine felt like it was missing terribly as it cycling thru these errors. i shut it down and restarted it seemed ok, but check engine light still on, when i tried to move it started to shake and cycle errors again. i shut it down again and restarted this time it was running ok. the check engine light was still on and we drove with thecheck egine light for approximately 400 miles stopping and shuting off engine several times.light still on. stopped for 1 hour to eat when restarting no check engine light on and has been working as normal today.

With no notice or warning while driving on freeway pulling horse trailer at 65 mph engine shut down and would not restart. hill assist light came on along with skid anti-sway motion and a wrench appeared in the indicator light. steering wheel became hard to move. had to cross three lanes of traffic to get to side of road in a construction zone while going uphill towing a horse trailer eventually restarted

In early september of 2019, i was driving my 2015 ford f-150 on a major highway at about 65 mph. suddenly, the vehicle stalled and lost all power as the dashboard lite up with some kind of traction warning. i drifted to the side of the road and put it in parked. the whole vehicle shook significantly at this point. i turned the vehicle off and waited about 2minutes. i started the truck up and went on my way with no problem. (note: this incident was a serious safety issue as i was on a major roadway in heavy traffic. my 10 and 8 year old grandchildren were in the back seat). a few weeks and a couple hundred miles later, i was on a narrow mountain road going about 45 mph when the exact same thing happened. i took the truck to the ford dealer after both occurrences, but they could not find anything wrong with it, and said there was nothing they could do. i'm reluctant to drive it as this situation could cause an accident. it only has 42,000 miles on ...

The transmission drops out of gear and cannot be reengaged until vehicle is stopped shut off and restarted. problem has increasingly gotten worse from a mild fail to engage after a three point turn around to current condition. last most dramatic event occurred yesterday while on i-75 near lexington, pulling a travel trailer when it dropped out of sixth gear in a construction zone with a tractor trailer behind the truck. vehicle went to idle, wrench light appeared. there was no throttle response and transmission would not reengage. had to pull off the side of the road and shut vehicle down. upon restarting transmission worked normally until reached destination. two ford dealerships have not been able to diagnose this problem. only one error code has appeared, p0731. transmission fluid was added and code was cleared. problem was not resolved. other dealership could not replicate problem with no codes present. ford customer care has been contacted regarding this issue. appointment made with local dealer. however, evident they do not know how to resolve. *tr

Traveling at highway speed on the interstate my vehicle downshifted out of my control from 5th to 1st gear very suddenly.

I bought this truck brand new from the dealer 8-2015. as of august 1, 2019 the truck stated vibrating between 50 mph and 75 mph while driving on the highways. i am getting a vibration from what appears to be my drive axle. it is most prominent when letting off the throttle and coasting from 75 mph to 50 mph. you can feel it in the steering wheel and you can also hear it.

While in motion, at highway speeds on a highway and sometimes slower speeds on town streets too, my truck would suddenly start flashing multiple errors and the throttle would immediately be unresponsive. in 1 second i was dead in the water. the truck would immediately start slowing down due to lack of propulsion and the engine would have a very low rough idle. the throttle would not work at any speed. the only way to recover control of propulsion was to come to a complete stop right where the problem occurred (very dangerous), turn off the vehicle and then restart the vehicle. after restart the problem would completely disappear. until it happened again. this problem appeared 3 times in 1 week, all while the vehicle was traveling uphill. i was lucky to not be in traffic at the time. i took the vehicle to the dealer and they reported the vehicle needed a new throttle body, and that this issue was common and that a recall was not in place. the repair cost is over $500.

My 2015 3.5 f150 has been experiencing sudden downshifting at random times. typically, it happens once every hundred miles or so and takes the gears from 5 or 6 all the way to 1 or 2 gear at highway speeds. it is scary especially since we are supposed to be pulling a camper across the west for a few months. first the dealership said that it was a throttle body issue so i replaced that. now they are saying that it is spark plugs. apparently, four out of six misfire at the same time randomly which they said would cause the downshift. however, i just had them replaced with new boots three months ago. the issue did start after a dealer transflush but i do not know if it is a coincidence or not.

The truck will, without any warning, just basically cease to run. engine will shake, truck will quit moving under its own power, and several service advisories will come up on dash suck as "service downhill assist, service traction control", and a few others. i stop, put in park, turn off truck, restart, and it will be clear and will go again. this has happened 5 times and is currently being looked at by a mechanic. 3 times has happened on roads with very light traffic. twice, while getting on interstate. truck has 87,000 miles.

While driving on the highway through town at 35mph lost all acceleration, message on the screen said see manual, service advancetrac, hill descent control fault and collision warning not available. stopped in the middle of traffic, could not get off the road. shut vehicle of then on again and drove for half a mile before it did it again. this time i was able to move from traffic and park safely vehicle will idle but not move. this happened ten times in two days in varying traffic conditions

Takata recall

While driving between speeds of 55-70 mph on the highway, the vehicle entered "limp-mode". the driver notification panel displayed "service traction control, service engine," and displayed an the airbag symbol. vehicle immediately lost the ability to maintain speed or accelerate. the engine remained on with power steering and brakes. after maneuvering out of a travel lane onto the should, the vehicle shuttered at low speeds until the engine was turn-off. after restarting the engine, the notification were removed and had no issues at that time. after nearly 1000 more miles of driving, the vehicle had the same issue while driving approximately 65mph on a highway. the same symptoms were demonstrated. after restarting the vehicle from the shoulder of the highway, the vehicle drove with no issues. ford dealership in seaside california advised that it was a faulty electronic throttle body. the repairs are not covered outside the bumper to bumper warranty.

While driving my 2015 ford f150 platinum (v6 eco boost) on an hwy (70 mph) the truck encountered loss of pedal response and three warning light as i coasted to a stop in heavy traffic. these three warning lights: hill assist traction control, advanced trac warning indicator, driver assistance indicator. the truck to transition to 'limp' mode (accelerator and power steering doesn't work) which a dangerous and scary. most 'limp' mode incidents have occurred while descending downhill, has occurred seven times so far. i have taken it to the dealer, and they just clear code and say your good ($130 diagnostic fee). then the error occurs the same day. with more online research there a massive problem with the throttle body which causes this to happen. there needs to be a ford recall for this before someone gets hurt.
