As I was driving about 40 mph, the truck suddenly decelerated to almost a stand still. Two messages appeared on the dash board info system. Service needed for hill assist and advance trac, or something similar. I had to drive home, half mile, at a walking pace which was as fast as the truck would go. There was no warning. This is a deadly flaw. How could you not have Ford F150 in your database?

There appears to be "slack" in the drivetrain, as if it has a bad universal joint. There is often a clunk when you step on the gas when pulling away from a stop. It was recently checked at the dealer while in for an oil change. They said they found nothing wrong with it. I read on an F150 forum site that this is a rather common complaint. The dealer has told others that there is nothing wrong with it. It happens often when pulling away from a stop sign but others have reported it also happens to their truck while cruising down the highway and stepping on the gas pedal.

The contact owns a 2016 Ford F-150. While driving 35 mph, the vehicle lost total power as it rumbled and shook. Also, various warning indicators illuminated, including the powertrain fault, stability control, air bag, and check service manual. The contact stated that the running board failed to retract. The contact pulled the vehicle over to the side of the road and restarted the vehicle. The vehicle was towed to Ford & Lincoln of smithtown (440 jericho turnpike, St james, NY 11780(631) 265-2340), but the cause of the failure could not be duplicated or diagnosed. When the contact retrieved the vehicle several hours later, the failure recurred and the vehicle was towed back to the dealer. The manufacturer was made aware of the failure, but did not assist. The failure mileage was approximately 6,000.

The contact stated that the vehicle consumed too much fuel and the air conditioning blew hot air. Also, the oil low pressure warning indicator illuminated and flashed off and on. The contact also stated that the brakes squeaked and the front passenger side tire deflated. The vehicle was taken to the dealer (koons Ford in sterling, va) for diagnostic testing. The dealer found nothing wrong with the vehicle; however, the failures recurred several times. The contact stated that the vehicle was taken to the same dealer several times and, during one of the visits, the engine was replaced without the contact's consent.

Hill assist and autotrac malfunction. 2016 Ford F-150, less than 8,000 miles. Warning indicator suddenly comes on and vehicle loses all power going from highway speed to 2mph in seconds without warning. Happened 4 times in two weeks on straight, level road, dry and clear conditions. One time was on the highway at 65mph, others were city roads around 25-35mph. One time was after a normal right turn, others just randomly while traveling straight. I took it to the dealer and they replaced the throttle body but researching online, this appears to be a common problem with F-150S. There should be a recall considering the danger posed from a vehicle that suddenly loses power and decelerates without warning. I also read another account where replacing the throttle body did not solve the issue so it remains to be seen if this fix works on my vehicle.

While operating my 2016 Ford F150 lariat FX4 in 4A mode, I hear a audibly low noise emanating from the front end of the vehicle as I accelerate. This noise is accompanied by a slight vibration that is felt transmitting through the accelerator pedal. The noise and vibration is only detected while accelerating and only while engaged in 4A mode. There is no detectable noise or vibration in 2H, 4H, or 4L modes. This condition is present under normal operating conditions and during ideal weather conditions. Driving on flat, straight highways and roads, nor turning or towing does not affect the noise or vibration that I am detecting from the front end of the vehicle.

The truck has had issues with the hillassist failure, then check engine light then wrench light causing the truck to go from 45 mph to 2mph without notice. The throttle bottle also went out on this truck causing the truck to go from 45 mph to 2 mph in traffic, this is the Ford wrench light. On two seperate occasions, when starting the truck and releasing the parking brake, a parking brake malfunction light flashes, then when trying to move the truck into gear it will move from park to drive to reverse, but will not move. Please contact me asap. I have a detailed list of dates and occurances along with all email conversations with Ford. Ford soes not believe this is a problem and seems to ignore the safety concerns.
