Problems with 2015 Ford F-150 VEHICLE SPEED CONTROL

Cruise control shuts off during operation. intermittently will not turn on. analog speedometer will indicate speeds in excess of 40mph slower than real speed. stuck at 40mph when comes to complete stop.

Driving down the road today being mindful of the speed limit since i just got a speeding ticket two weeks prior. i looked at the speedometer and it read 62. i know the difference i speed variation just from driver feeling and experience. well i applied the brakes and the speedometer did not move. when i reached my destination i put the car in park and noticed my speedometer was frozen at 40 mph. so now according to the trucks brain 40 mph = 0 mph

Vehicle accelerated of its own accord driving straight on highway. took to dealer (village ford, ocala, fl), they ran black box and did warranty work. a few weeks later, vehicle accelerated again of its own accord while attempting to slow down to make a left turn. vehicle collided into a tree.

I picked up my 2015 ford f150 on thursday of last week because the master cylinder was leaking and caused my wife to lose her brakes while driving on the highway. i drove my truck to our family reunion about an hour and half away on saturday which was 2 days after i had picked my truck up and the cruise control would not shut off by taping the brake. my wife and i were traveling on a highway and i was in the slow lane with the cruise set at 72mph. i was approaching the vehicle in front of me, so i looked in my left mirror and noticed a car coming up beside me. i was unable to pass, so i touched the brakes to disengage the cruise control and i looked back in my mirror again to see if the car beside me was going to pass me soon. my wife then said what are you doing? i told her i am going to pass this car in front of us after the car beside me passed us. she then said well you better slow down because you are about to hit the car in front ...

Randomly the hill start assist control error would come up. additionally, service advance trac error would come up and the truck would go into some sort of limp mode with no acceleration allowed. finally, the truck started running really rough. all these things would happen while i was in motion and or turning. i have been broken down on the side of the highway 4 separate times now. everything is really random and can't be replicated. it's done this about 10 times now and the dealer has no idea how to fix it. my truck has been there for over a week with no remedy.

Driving on highway at 60 mph, climbing slight incline, multiple warnings regarding hill assist, abs, traction control, etc. populate on dash. truck goes in to "limp" mode, steering becomes stiff and speed reduces until it comes to a rough idle.

Tl* the contact owns a 2015 ford f-150. while driving 70 mph, the vehicle's throttle completely failed and several unknown warning indicators illuminated. the contact was able to coast the vehicle to the side of the road and restart the vehicle. the vehicle was taken to holmes tuttle ford lincoln (660 w auto mall dr, tucson, az 85705, (866) 930-6255) where it was diagnosed that the throttle body needed to be replaced. the vehicle was repaired. the manufacturer was not notified of the failure. the failure mileage was 79,500.

When i started the car, put it in drive, the truck went to full throttle on its own without touching the accelerator, and it took off at an excessive speed. i tried braking, but it just threw me into a power slide. so, once i was finally able to straighten the car without flipping it, i could turn loose with one hand and kill the engine. that's the only way it would stop. i was forced to go through the yard with things flying out of the bed of the truck ruining a 5 gallon can of paint we had mixed to paint the inside of the house. i am a professional truck driver, and this scared the death out of me.

Tl* the contact owns a 2015 ford f-150. while driving 60 mph, the vehicle stalled and the engine would not restart. the contact attempted to restart the engine; however, the vehicle began shaking and would not stop. also, 'hill descent control fault' and 'service advancetrac" appeared on the instrument panel. the vehicle was towed to paducah ford (3476 park ave, paducah, ky 42001, (270) 444-0011) where it was diagnosed that a new throttle body needed to be installed. the contact planned to have the vehicle repaired this week. the manufacturer was made aware of the failure and stated that the vehicle was not included in a recall. the failure mileage was 104,000.

My 2015 f150 ecoboost has 79,156 miles on it. over the past 3 days the truck has repeatedly lost power while driving in traffic on the highway. the rpm will drop down to 500 rpm, rough idle, no acceleration at all, hill assist light wrench light check engine light passenger air bag light and see owners manual pop up on the instrument panel. took my truck into ford today and they replaced the throttle body under my extende warranty not their emissions warranty as stated in their owners manual of 8 years or 80,000 miles. called ford and they don't know about an emissions warranty in their owners manual. looked online and youtube to discover this problem is not just me and frequent with others. this can really cause a horrible accident. luckily i'm a cdl driver and was able to safely get over on the shoulder this time. i'm not confident replacing the throttle body was a fix as it is a bandage to happen again at any point in time. this truck now is compromised and i wouldn't want any of my family using it or depending on it.

My ford truck has had issues with lurching while at a stop, hard downshifts. and as of friday night, going from 75 mph on the interstate to a dead standstill as though my transmission locked up. almost created a pileup on interstate 70. then would have rpm btwn 5 to 8 going 20 mph. 2015 model v8 with ecoboost. my year was not part of the recall announced but the symptoms described in that recall fit mine exactly. i am going to file a complaint with ford as well.

Speedometer reads 15 mph when parked and 15 mph more than actual while vehicle is in motion.

I was travelling along at highway speed and suddenly the truck lost responsiveness to the accelerator pedal and went into limp mode. i had to move over to the shoulder of the road rapidly to avoid becoming a hazard to other drivers as my speed was slowing significantly. this has happened on several occasions on both surface streets and on highways/freeways. i have been told that the electronic throttle body is faulty. this fault has created a hazard for me and other drivers due to the sudden loss of power and the hazard that represents on roads with no shoulder.
