Vehicle geared down without warning, several occasions it would stay geared down on an interstate. I would have to pull over to get it to perform properly. Took it in to the local Ford dealership for repair and it cost me $7000 to replace transmission, immediately afterwards it continued gearing down which happened to be an issue with the power control module. I know the 2014 have been recalled with the same issues, and feel the 2015 should probably also be included in the recall.

Truck will down shift automatically to 1st gear at times exspecially when pulling a trailer of any kind when slowing down, (example) getting off a highway ramp slowing down to the intersection. I just read they are recalling 2014 with that issue, 2015 also has the same issue, atleast mine does. Has probably done it 6 times, all with a trailer on the truck.

My latest issue is with the 2.7 ecoboost engine. I had a total failure of this engine last year and am still awaiting a replacement that I am paying for. This is unacceptable as I had this vehicle serviced according to maintenance schedule. I also have had systems report failure such as the hillside assist and the electronic parking brake. Additionally, the automatic transmission has locked up in third gear quite a few times. There are other issues such as a leaky oil pan and such.

The contact's father owns a 2015 Ford F-150. The contact stated that while his father was driving approximately 40 MPH, the vehicle downshifted inadvertently. The vehicle was steered into a parking lot where the driver observed that the engine was revving without depressing the accelerator pedal. The vehicle was turned off and was not able to be restarted. The vehicle was towed to the residence where a handheld diagnostic machine retrieved DTC code: P0707. The vehicle was towed to a dealer where it was diagnosed that the leadframe needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 52,000.

I was driving a couple of days ago and all of a sudden I got this wrench icon on my dashboard and my 2015 Ford F150 went to limp mode from 70 mph to 35 mph for no apparent reason. I've noticed the PRNDM21 is grayed out. Luckily after about 10 seconds, it went back to normal. Today Feb 23, 2024, I went to pick up my girls from school and this wrench icon shows up again, this time it felt like my truck was not responding to acceleration, it's like it had a mind of its own. I was pressing the brake but it felt like it was not responding so I almost rear-ended another vehicle. Luckily, there was room on the right lane so I swerved immediately not even thinking if there was any car so fortunately, after about a minute, the car went back to normal. I was so scared driving the truck after I picked up my girls to school, I was hoping it wouldn't happen again as there were a lot of kids crossing the school. When I got home, I used my code reader and it came up with P0707 and P0706 (Transmission Sensor a Circuit Range Performance and Transmission Range Sensor A Circuit Low) issues. I contacted a mobile mechanic and scheduled for a repair this Sunday. Hope they can get this fix asap!

Throttle body failure while driving resulting in immediate need to pull off the road as vehicle lost power and a lot of warnings lights going off. Very dangerous at Haigh speeds in traffic.

- Newbury, VT, USA

Driving 68mph with cruise control engaged, truck violently jerked. Gear indicator went to 1st and started flashing. There was no gas pedal response. The truck was just coasting. About 10 seconds later, the gear indicator went back to 6th and resumed normal operations. This seems to be the same lead frame issue earlier f150s had with this transmission but no recall has been made for the 2015-??s. This is a serious safety issue and needs to be addressed by Ford

My 2015 F-150 3.5L ecoboost experienced a sudden loss of power during highway speeds and shut off. I was in rush hour traffic and almost caused a few accidents as my truck seemed like it went into "limp mode". While my steering wheel was tight I managed to get off the road safely with no power whatsoever. My idiot lights were flashing like crazy and stated "Advance Trac Service" and "Hill Start assist not available". I let the truck sit for a bit and restarted it. It ran solid another 15 miles. Today I'm getting Advance Trac message: "Advance Trac Service" and "Hill Start assist not available", all while the engine check light remains on. I have read multiple issues similar to mine but there does not seem to be a recall for this. This is a VERY unsafe ordeal and very scary. Had my daughter been driving, this may have been an accident for sure. I see Ford "extended" the warranty to cover any issues. But I do not drive my truck that often and I find it hard to believe nothing is being done about the "throttle body" issue (from my reading). This is even happening to Ford trucks overseas. I get they do not have any say in the US, bu it does show this is a MAJOR issue.

While driving normally down the freeway the transmission on my 2015 Ford F-150 King Ranch(4x2) jumped into neutral, the "D" which was lite up orange started flashing orange to white then when white, the "wrench" light can on check engine light came on, the truck had power but when you pushed on the gas it only revved up like it was in neutral. Thankfully we were able to pull to the side of the road without getting hit, and I turn the truck off, that seemed to "reset" the trucks computer and the truck was able to go into gear, we drove it home immediately without another incident. This was the second time it happened, I thought the first time maybe I did something wrong, but it is obviously a software problem with the transmission. My son and I could have been killed, this is a serious problem that needs a recall, I have done some basic research in the past 24 hours and there are similar problems all over the Country.

The transmission lead frame failed while traveling down the road under normal driving conditions. We came to a stop and the truck revved very high on its own. My husband shut the truck off and put it in park. Afterwards it refused to start it would not even crank. We had a mechanic hook his computer to it and received 3 codes for the transmission range sensor which tells the vehicle what gear it's in. I have had several shops and a dealer tell me there's been many instances of this part failing. It's about a $2000 repair. Luckily for us this happened on a less busy road but it was still dangerous to be in the middle of an intersection unable to move. I can only imagine how bad this would have been in a busy town. I have not had the repair done at this time but will be soon.

My 2015 3.5l ecoboost had the Exhaust manifolds replaced back in 2018 when my truck had 51,909 miles on it and now at 90,000 miles the new manifolds warped and snapped off a stud bolt to which the American Fork Utah Ford Dealership said that since it was over a year ago even though it was a known issue that was covered under warranty I will have to pay out of pocket over $2,000 per manifold... this is a known issue with the manifold warping and causing exhaust leaks when the stud bolts snap off. Ford needs to recall this design flaw and pay for the fix.

the truck has been acting up for several months now. it has been throwing out strange codes when attempting to start {parking brake malfunction, oil light, power train system default, ect} and often times it WILL NOT CRANK unless we hook it up to a battery charger for just a bit of time. The truck has a new battery that was installed by autozone, where it was bought {6 months ago}. Since we were in town, we stopped by autozone to get them to attach the code reader. {power train system and ABS malfunction} while driving, later in the day, the trucks auto start/stop system turns itself on and stops the truck dead in its spot.(danger: we were pulling onto the road {fm 2100} during rush hour traffic, when the trucks system went haywire and stopped us dead in our tracks in the center of both turn lanes and two of the main lanes.) there was no restarting, nor were we able to get the gear to change into neutral in order for us to be able to move it out of the main roadway. when we were finally able to move it, we hooked a fully charged jump box {one rated for up to semi truck sized vehicles} to it to get it started, and it simply would not crank for quite a while. at this time, we took the opportunity to recheck the oil level, which was set at full. After several minutes of begging "the truck" to just start so we could just take her home, it finally cranked up and home is where we took her. the truck has 19771 original miles on it. it was drove off of the show room floor, back in 2015, with 6 miles on it, and has had absolute regular maintenance and has only had one owner.

Vehicle shifts into 6 gear on takeoff causing vehicle not to accelerate and causing vehicle to creep when I needed acceleration almost causing accident with oncoming traffic. While driving 60 miles an hour the vehicle shifts down to 2 gear. I dropped the vehicle off at the ford dealer, They diagnosed it to be the connected molded lead frame input shaft speed sensor these are not readily available with no estimate when they will receive this part. I did a search and found that there was a recall on this up to 2013. this part almost got me killed and now they can't even tell me when this will be available my vehicle has been at the dealer for almost 3 weeks waiting for this part. they are telling when they receive this part it will cost approx. $900 for the repair I feel this should be included in this safety recall this is a very dangerous defect that almost took my life.

F150 starts to lose power and shudder/vibrate about 60% of the time when driving. Picking up speed, truck lost half power and engine light starting flashing. When it caught gear and speed, the light stopped flashing but the truck continues to shudder and vibrate like crazy.

I was pulling out into the road, and the Engine cutout, then slowly came back. I did some investigation, and the truck transmission cooler lines had corroded through. Luckily I was not in heavy traffic. There had been no obvious signs of failure. I've owned numerous other vehicles while living in Northeaster NY with no major corrosion failures.

accelator stuck to the floor a couple of times when gassing it to pass other cars on the roads. The pedal would actually will stay pressed down even when my foot is off the pedal, it will speed the truck up even when pressing down hard on the brakes. when i got it to stop and cut the truck off while in park and turning the key the rpms were going absouletely nuts. looking to see if this is a common occurance. thanks in advance!

While the vehicle was running, it spontaneous entered "limp mode". The wrench light came on the instrument cluster and warned that the blind spot and rear collision systems were offline. The gear selector indicator also disappeared. After the vehicle was shut off, it would not restart for numerous attempts. When it did, it was being driven to the dealership when the same series of events occurred at a red light. Afterwards, the truck struggles to accelerate. The dealership has diagnosed a lead frame failure, which was a recall on the previous generation F150s. Based off discussions online, it seems that this is common.

The contact owns a 2014 Ford F-150. The contact stated while driving approximately 30-35 MPH, the vehicle downshifted and the RPM-??s increased without the vehicle accelerating. The contact then stated that the transmission inadvertently downshifted to 5th gear. The powertrain malfunction warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and produced DTC codes: P061A, P0720, P0722. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was transferred to the NHTSA Hotline and provided a case number. The failure mileage was approximately 127,500.

My 2015 Ford F150 has 108K miles. While driving on 2/21/23, the engine started missing, several engine warning light began illuminating. I was able to pull to the shoulder and stop the engine which was missing badly. After allowing the engine to completely stop and turning the ignition off, I allowed it to settle for a moment, then I restarted the engine. I placed it in gear and attempted to drive again, but the same missing and instrument cluster faults recurred. At this point, I had it towed to Loveland Ford, in Loveland Colorado. After evaluation, I was notified the Throttle Body had failed which also caused the instrument cluster faults. Upon reading about the Throttle Body, one of the articles indicated this has been and issue for Ford F150 years 2014 -2016 produced in Dearborn and Kansas, but that Ford had voluntarily repaired vehicles with issues via extended warranty when reported. My vehicle falls in the date range and was produced in Dearborn. This is a very dangerous condition and had this occurred on a busy highway, would be a danger to me as well as other vehicles.
