The factory/ dealer installed tow brake controller does not apply enough brake power to stop trailer. When towing my 5th wheel(10000lbs)it works fine when I manually apply the override button but when I apply the brake pedal the trailer brakes don't get the command to engage with enough power to stop trailer, my truck is doing almost all of the braking. I have read online where many Ford f 150 owners are having similar issues. Ford says there is nothing wrong. I have been towing using the manual override switch or learning to slam on the brakes to stop. The trailer brakes do work almost when I slam on the brake pedal. I am sure that this shouldn't be happening because it's not safe.
During extreme cold the door latches freeze and can either not be opened or once opened will not latch closed. This has happened twice now. The vehicle had been sitting in the driveway overnight both times. There had not been precipitation for 24 hours prior to either event. After manually positioning the latches they would catch. On the second occasion they opened again. It was both rear doors both times. Both times the ambient temperature was in the teens with windchills below zero.
Vehicle lost power and flashed 3 warning messages. 1) hill start assist not available. 2) see manual. 3) service advance trac. In addition the service engine light stays on. All of this happened while I was making a left turn in traffic almost causing a collision. This is the second time it has happened. After first time dealer was contacted and service department reported no problems found. Appointment currently scheduled to look at it again.
While driving on the highway at 75 mph the truck shuttered violently and the engine shut down. Immediately it flashed a warning that the "hill climb assist" malfunctioned followed immediately by a wrench symbol notifying that service was needed then another warning about the advance trac system then back to the hill climb assist symbol. All of this happening while the car behind me is almost sideways trying to avoid me. I eventually made it to the right shoulder of the highway. As I read the various warnings it said to refer to the owners manual with regards to the hill climb assist. I turned the ignition off, pulled out the owners manual only to find a description of the hill climb assist feature. After waiting for about 5 minutes I decided to turn on the ignition. The truck started without issue and I continued home cautiously in the far right lane.
Ford is discontinuing the safety feature sync my Ford touch service which was part of the purchase agreement. This is a safety feature of the vehicle providing operator assistance, traffic alerts, turn by turn directions, and other safety related services. They are not offering a replacement or option to upgrade to the new sync 3 service. I am being cheated on what I purchased as described on the window sticker and in the owner's manual.
I own a 2015 f150 with a very frustrating issue. It seems the door locks cease working during cold temperatures. The issue is sporadic, and affects either all doors, or some of the doors when it occurs. The first time I noticed this, was in the morning. To my surprise, my son was able to open my door without unlocking it. I recall locking it and hearing the beep the night before. I asked my son to shut the door, I clicked the lock button twice and heard the honk. I then went to open the door and it opened! my truck had been left unsecured through the night, and many other nights for all I know. I thought this may have been a fluke, so I went about my day, and did not experience this again for about a week. When I experienced this again, I was on a lunch break and I had driven to a local spot where I like to jog. When I do this, I leave my key in the truck and use the keypad feature as to avoid carrying everything with me. I pushed down the locking rod, shut the door and went on my jog. When I returned, I entered in my code, I heard an unlocking noise (turned out to just be my tailgate), but I could not open my door. I tried again, but again was unable to open my door. I tried my other doors, no luck. I was stuck without keys, wallet, phone (in my truck). I had to find a ride home to get my other key to manually unlock the door. I ended up missing the rest of work, even missed an important meeting. This last happened with my son in the back seat, where he was unable to open the door from the inside, and I was unable to open the door from outside, and this simply got my imagination running to the potential safety risk. It is now at a dealer who cannot duplicate, so no fix. This all not to mention the inch of water I had at my feet when it leaked, or the loose part in the driver door knocking around that they "cant" duplicate. Major qc concern.
2015 Ford F-150 manual on page 263 has instructions for proper setup of an equalizing hitch for towing a trailer. The instructions call for return of the front fender height 25% of the way from height when loaded with trailer to height with no trailer. This is the opposite of recommendations of the hitch manufacturer who recommends front fender height to 75% of the way from loaded to unloaded condition. In the words of the hitch manufacturer "why would you put on an equalizing hitch and not set it up to do what it's intended to do?". The result of the instructions in the Ford manual would be inadequate equalization, and therefore loss of steering with a resulting potential for accident. I think this is just a typo, but have been unable to find anyone at Ford who will listen and find someone technical enough to check it out.
