2015 Ford F-150 complaints

Lead body failure. Causing it to downshift suddenly when driving, higher rpm, and non-start condition.

I noticed in the fall of 2024 that my transmission stared shifting hard between 30-40 mph during acceleration. I had the local Ford dealership check out the issue and they stated I needed a new transmission and included an estimate. I decided to seek information from 2 independent transmission shops and they could not confirm that I needed the transmission replaced at that time. The vehicle has been driving fine and I recently started to notice the hard shift again at 30 mph. Every once in a while, when the hard shift occurs, it seems like I lose power to the drive train and my vehicle slows down to about 15 mph and vehicles need to go around me. It only lasts for a few seconds and then the acceleration will continue to drive normal. I do notice an increase in RPM's from time to time as well while shifting around 30 mph but does not feel like it is slipping. Once through this area of shifting, the vehicle operates normally shifting through other gears. There were no warning lights or other symptoms leading to this issue. I did notice that there was an article posted with a possible transmission issue from this year vehicle that is being investigated concerning sudden down shifting while driving. Here is the article [XXX]. I am wondering if this is part of this issue? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving with cruise control engaged, on dry road, no significant weather or wind gust, cruise control disengaged. Tried to reengage but took numerous tries. Once engaged, Tried to CNCL the cruise control and it would not disengage. Had to jump on the brakes. Seconds matter.

A recent recall on F250’s, 350’s and other ford fleets on the reverse camera not operating intermittently. It’s a known issue. I reported it to my local ford dealer back in 2019 and they said I would need to drop the truck off for over a week just for diagnosis. Single vehicle family here. It’s a big loss of situational awareness in areas like parking lots and with more people walking around with their phones in their faces like zombies, and with the camera inoperative, has greater potential of loss of life or damage to property.

The transmission will downshift from 6th to 5th at hwy speed....it also at other times , will only go from 1st to 2nd gear and no farther...wrench light comes on each time.I have to pull off hwy and slowly try to take off to get transmission to shift correctly. A lot of times pulling to side of road puts me in a dangerous situation.When it won't shift past 2nd gear I have to try to pull over immediately as it over-revs.I am taking it to an independent service center and dropping it off for their confirmation as sometimes tranny will shift fine for 2-3 days and then go back to malfunctioning. It started this about a year ago, but I had neck surgery then and am now just getting back to driving.The wrench light comes on each time , along with the transmission fan.The truck is available for inspection any time.

Vehicle suddenly downshifts into a lower gear while accelerating from a stop or cruising at constant speed. Wrench icon comes on the dash and check engine light comes on. Turning off the engine and back on will stop the issue and restore the power.

Transmission abruptly shifted down from high gear to low gear causing it to lock up at a fast speed. My son hit his chest on steering wheel bc it was so abrupt

Sunroof was replaced under warranty due to track being broken. Now the sunroof is leaking and the shade will not open. There has been several recalls for sunroof issues. Dealership says my vin is not included. This seems to me to be a recall issue for safety. If the sunroof is broken it could cave in or fly off. Especially since it is leaking and won’t open and cannot see the problem. Dealership wants to charge me over $200 just to look at it. This is unacceptable.

My truck downshifted into 2nd gear after i was in 6th gear, now my transmission is slipping into 4th gear. But when i press the accelerator a little harder it’ll shift better but it’s not practical in a city

The manufacturer was not notified of the failure. The approximate failure mileage was 125,000.

The transmission is a safety issue and is available for inspection. The six speed automatic has a 5th to 4th downshift that is regularly rough and can be jarring at times. A few weeks ago on my way home from work while driving 30 mph around a small bend the truck shifted from 4th to 2nd on its own and bucked so hard that it scared me and brought my hands off the steering wheel and made my back sore for the next day. This is a blind bend because of the shrubbery in the front yard at the bend and it is also at the beginning of a school zone. This could've been a worse situation if there would've been a car or school bus going in the opposite direction. This was certainly the worst one yet but there have been similar situations where the truck jarringly shifted from 4th to 3rd on its own. The problem has not been reproduced, confirmed or inspected as mentioned above. I have read multiple stories stating very similar or even the same occurrences on the forums. The lead frame in the transmission seems to be the leading cause for this issue. Others have been to the dealer, had the computer reflashed and were told it just needs to relearn their driving, only to have the issue return. After seeing these stories and now reading about the investigation into the issue I've been holding off to see what happens as I do not want to waste time and money to not have the issue fixed. There were not any warning lamps, etc before or after this issue. I have noticed that when the jarring shifts

2015 Ford F150 XLT 2.7L, 6 speed auto, Crew CAB, short bed. Yes, you can inspect. Going down highway around 45-50 MPH, without warning or warning indicators, transmission suddenly downshifted, rear wheels locked momentarily, RPM's ran up high and vehicle slowed down abruptly in the middle of traffic. Wrench light on dash appeared and disappeared. About 5 minutes later driving on freeway, transmission would not automatically shift up to the next gear, stayed in a low gear for a minute, then finally shifted up. Vehicle is currently at Ford getting inspected. Did not drive the vehicle since the incident on 3-29-24, except to go to the Ford dealer.

It’s been several times that I’ll be driving, sometimes on residential roads and once getting onto the highway. The transmission will suddenly drop down into first gear and I’ll have to limp off the side of the road until I’m going slow enough to be in first gear, then I can go again. Or I’ll lose 1,2 and 6th gears so I’ll have to pull over, turn the truck off and start it again. Then I’ll have gears 1-6 again.

I have owned my 2015 F150 SPORT 2.7 ECO BOOST since it was new, and occasionally it downshift's mainly in town from 5th gear to 1st gear. I thought this was my fault until I heard about the safety concern. I have mentioned it to ford, but was told that downshift's were normal? Anyway I an now concerned this could happen on the interstate which I don't drive on regularly.

While driving at random times trans will go into a limp mode and have only 3 gear speeds. Sometimes either a wrench symbol will come up or a check engine light will come one. When this happens it’ll stay in a limp mode til ignition is cycled for it to reset. Also while at low speeds it has dropped me from 4th gear to 1st.

Transmission malfunction by sudden downshifting to first gear at highway speeds. This caused my rear wheels to lock up and skid as if I had slammed on the brakes and temporary lose control of the vehicle, which is extremely dangerous on the highway. It has occurred multiple times. There were no warning lights the first several times this happened. They check engine light did come on after about the 6th time it occurred.

I was driving at around 45mph and my truck suddenly downshifted automatically and almost brought me to a complete stop. It finally shifted back up and I was able to return to the proper speed. If this would have happened at higher speeds I could have been in an accident. Event at 45mph, had I not had my seatbelt on it would have thrown me into the steering wheel.

The contact owns a 2015 Ford F-150. The contact stated that while her husband was driving 35 MPH, the transmission downshifted to a lower gear unexpectedly. There were no warning lights illuminated. The contact stated that initially, the vehicle would sporadically downshift to a lower gear. After a year, the vehicle started to sporadically downshift more frequently. The vehicle was taken to an independent mechanic, where it was diagnosed that the transmission needed to be replaced. The vehicle was repaired with the installation of a new transmission. The dealer was not made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

Truck while turning right or forward will for no reason goes into lost traction(dry road) and truck downshifts and loses power. Very dangerous as there is no warning and potentially can be hit from behind since no brake lights are engaged. Recently read article that other trucks of this year and make are having same issue. I have taken into shop and awaiting what is the problem.

Broken exhaust bolt on passenger manifold. Exhaust leak... Felt as though Carbon monoxide gas was entering cabin portion of truck. Smelling of exhaust in cabin of vehicle. Made wife and kids nauseated and lightheaded. Did research and found out that ford had a poorly designed manifolds and didn't utilize all exhaust bolts. In turn caused the #8 bolt to snap and manifold to warp and release exhaust fumes

Truck will on occasion downshift into a low gear out of nowhere and feels like the rear axle is going to rip out of the truck.

The transmission will down shift without warning. It has occurred 4 times in the last 60 days. Near miss accident in one occasion.

The contact owns a 2015 Ford F-150. The contact stated while driving at various speeds, the vehicle failed to maintain the desired speed while the accelerator pedal was depressed. Several unknown warning lights were illuminated. The vehicle was taken to a local independent mechanic, where it was diagnosed; however, the cause of the failure was unknown. The contact stated that unknown repairs were completed by the local independent mechanic. The vehicle was repaired but the failure reoccurred. The vehicle was scanned with an OBD2 scanner and DTC: P061C was retrieved. The local dealer was contacted. The vehicle was not diagnosed or repaired for the recent failure. The manufacturer was made aware of the failure. The failure mileage was approximately 147,000.

Full transmission failure after switching to 4 high on snowy highway. Speed during shift was about 50 mph. We were left stranded on a busy highway outside of Steamboat Springs, CO in wintry conditions for almost 2 hours while waiting for roadside assistance. Vehicle was towed to Phil Long Ford in Littleton, CO. There was no warning on the dashboard until the “wrench” light went on as the truck lost power. The mileage on the vehicle at the time of incident was 100,368. Response from Ford was that the vehicle was beyond the warranty period. I was given a repair estimate of $9701.90 plus an inspection bill of $250.00. The truck has been towed to an independent garage for a new transmission. I have not been given an explanation for the transmission failure as yet. ( date of event: [XXX]) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was traveling [XXX] near Liverpool, PA at 60mph, the truck flashed a quick code on the dash and then suddenly downshifted from 6th gear to 1st almost spinning the truck as the rear wheels locked up momentarily. It would not upshift past 3rd gear and had to travel 35 miles home like that. I called my local Ford dealer (Parsons) and they said bring the truck in for diagnostic testing, so I did. Meanwhile I searched the internet to see if others had the issue. Turns out they did, BUT my 2015 with the 6R80 was NOT in the recall notice. Ford said it was the lead frame and needed to be replaced. IF it was a known problem, why not inform owners of these trucks. That said, Ford wanted $1500 to fix it, BUT they did not have the part. So I drove the truck (never with my family in it ever again) after I cleared the code with my reader...again traveling [XXX] @ 75mph it downshifted IN TRAFFIC. Luckily I was in the right lane and made a quick move to the shoulder to avoid being run over. In Carlisle, PA there are hundreds of trucking companies and warehouses, so the truck traffic is very heavy. That was it. I searched out the part, paid for it myself and had a Ford mechanic that does work on the side fix the truck. I have been a loyal Ford guy for over 30 years...I reached out to Ford via telephone, chat and even Facebook. All they say is it is NOT under any recall. Hard to swallow that when I am driving a $75K truck THEY built and they will NOT stand behind a $2K fix. Well goodbye Ford

A few years back, I was having an issue with my truck shifting hard. I actually took it to a friend's shop and he repaired it, for about $1600. They changed a "chip" in it. The vehicle was never inspected by Ford, or the police, or my insurance company. The problem was identified by the repair shop and taken care of, or so I thought. The issue seemed fixed for a while but within the last year the issue has begun again. The transmission will not shift at times. It seems stuck, which causes the engine to rev very high. I worry about causing lasting damage to the engine as a result of the transmission sticking.

Transmission downshift during constant cruise speed.

I have had the gasket for the oil pan fix two times. It is leaking again and told by ford that it will happen again. It is 1200 to have it fixed plus they have to keep it for a few days to make sure the seal is dry. If you do not check the oil all the time it could be low and lock up. I know other people that have had this problem. It is on the 2.7 Eco boost.

The vehicle has downshifted to a low gear several times since I’ve owned it new in 2015. Usually has happened when starting to slow down to exit the highway. Driver and passengers were jarred and thrown forward unexpectedly. Driver was startled. Backend of truck swayed. Dealer service has been told over the years. They said they were aware but there were NO RECALLS and Ford didn’t have a FIX as of yet. They said it was COMOUTER RELATED causing the transmission to downshift. I also said sometimes it takes longer than normal to shift from the start position they claimed they were waiting for a fix from FORD. Dealer inspected. No warning lamps or messages appear on the dash as a warning. They said they would inform me of any fixes for the problem as they came down from the manufacturer.

I was driving down the highway then my vehicle randomly dropped down to gear 2 from 6 and went from 65mph to 30 and redlined my vehicle. It was extremely scary and took it to the shop immediately and then they replaced my lead frame and cost me $2,000. I definitely believe it has damaged my transmission and won’t last as long now.

Was traveling 75 MPH while towing a trailer. Truck was in 6th gear cruising. No fault codes whatsoever, no warning lamps etc. Suddenly the truck briefly downshifted into 1st gear, then upshifted back to 6th gear again. Issue occurred during heavy rain. I cleaned the bulkhead connector on the transmission afterwards and put dielectric grease on the connector o-ring. Connector Did not appear dirty or corroded. Issue had not occurred again for 8,000 miles.

During the course of driving on the interstate at 70mph the vehicle decelerated and went to a lower gear. The dash panel of the truck did not show all of the gears available. An emergency stop on the side of the road and turning the vehicle off and back on temporarily resolved the issue. It occurred intermittently and without warning. The truck continued to show problems and was taken to a transmissions shop which checked the transmission, replaced a line for a small leak and said everything seemed to be in order. The cause was not found to be a lack of transmission fluid as the levels were normal. The truck continued to intermittently decelerate. The last time that occurred, the back wheels locked up while on the road. The truck is now sitting due to the safety risk it poses and the locked up transmission on the rear end. It is available for inspection upon request. My safety and that of others was at risk. The problem was not replicated in a service center. The vehicle was inspected beforehand but not after the last issue, (it needs a tow as the back wheels are frozen). There was a warning light for the engine camshaft that came on and the problem was diagnosed at Ford as a camshaft issue though they could not understand the deceleration issue. The truck was taken first to Ford then to an independent transmission shop. Due to the issue the truck is not in use.

[XXX]: check engine light was on and codes P2196 and P2198 were present. The dealer suspected it was the purge valve, causing the problem so they replaced it and reset the codes. 10/10/24: I brought the truck in to have it looked at due to the check engine light being on again. I was told the lead frame needed to be replaced but was on backorder. The bill to diagnose this was 196.80 and I was told I could still drive it. On [XXX], I had to bring my truck in to be inspected because while I was going about 70 mph it all of a sudden downshifted and jerked me forward like it was going to abruptly stop. The check engine light came on and I had to drive pretty slow to avoid a breakdown on the interstate. Very scary to have this happen in interstate traffic It could have easily caused an accident. At this time, It was brought to my attention that the downshifting could also be related to technical bulletin 1495. Since we couldn’t get a real definitive answer on what was going on and the lead frame was on backorder, I decided to try and have the case connector in the bulletin removed and replaced as well as do a transmission tuneup on 10/23/24. This bill cost me $383.77. All codes were cleared and all appeared to be working correctly. On [XXX], I was driving on the interstate at about 70 mph and my truck seized up again and jerked forward, again scaring me and potentially causing an accident. I drove it very slowly directly to a repair shop. It was there until November 7, 2024 after

Brakes failed all fluid leaked out

I am experiencing dangerous shifting failures with my 2015 Ford F-150 equipped with the 6R80 automatic transmission. My truck intermittently fails to shift properly, holds onto gears too long, or refuses to shift into 6th gear. It also enters fail-safe mode, displaying a wrench icon on the dashboard. Restarting the vehicle temporarily resolves the issue, but it keeps coming back. The truck recently threw diagnostic trouble codes P0720 and P0722, which are related to the Output Shaft Speed (OSS) sensor, a known failure point in the 6R80 transmission lead frame. Ford previously recalled 2011-2013 F-150s (Recall #19V-075, Ford Recall 19S07) for this exact issue because it can cause a catastrophic downshift from 6th gear to 1st at highway speeds, leading to loss of control. However, 2015 models were not included in the recall, despite using the same transmission and lead frame. I am concerned that Ford’s recall did not go far enough and that my 2015 F-150 should be included due to the identical symptoms and part failure. This is a serious safety hazard, as a sudden downshift at highway speeds could cause loss of control, an accident, or even fatalities. I am requesting that the NHTSA investigate this issue and expand the recall to include 2015 F-150s with the same 6R80 transmission and defective lead frame.

The sliding rear window assembly which is attached with 4 adhesive tape strips have come loose. The sliding window comes out of the frame and could become airborne if hit from the rear or in a front end collision. It is a very poor way to attach a sliding rear window and the failure rate is high. The bad part of this is most people are probably not aware of the problem other than the window frame will rattle sometimes when your on a bumpy road. It is a poor design and could be dangerous in any collision. The body and glass repair shops are aware of the problem on the rear windows of Ford pickups. This should be fixed with a recall before someone dies from the window becoming airborne in a crash

The contact owns a 2015 Ford F-150. The contact stated while driving at an undisclosed speed, the vehicle made an abnormal screeching sound while accelerating. There was smoke coming from the passenger's side engine. No warning light was illuminated. The contact was able to drive to the residence. The vehicle was taken to an independent mechanic. The contact related the failure to the exhaust manifold; however, the vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 121,000.

Several extremely dangerous situations occured within 6 months of purchasing brand new 2015, F-150, 3.5, 4x4 ecoboost king ranch model. While driving on interstate, in rain, passing an 18 wheeler, without warning forward collision lights go off and truck begins slamming the brakes on by itself and the car behind me had to slam on his brakes to avoid a SEVERE crash. I brought truck to dealership they checked it out and said they wasnt sure why it happened and reset the computer, and put me back on the road. It continued to happen 2 or 3 more times until I realized it was only during rain, and when on side of 53' semi truck trailers. The last time it happened was a very dangerous and unnerving experience. truck suddenly begins slamming brakes on again going thru a major city on the freeway in heavy traffic. I brought the truck into dealer, and told them i wasnt driving it until they fixed it.The first year of ownership my truck was plauged with issues. IT constantly went into limp mode while on the freeway. I was working over 3 states and the truck would go into limp mode if I accelerated to pass. I went to every ford dealership shop along the interstate for a 300 mile stretch over the next 4 years while working away from home . Most of the problems were while under warranty. finally they updated software and it stopped. This was a very dangerous problem and the dealerships werent really very helpful. My truck stayed in the dealership shop more than 60 days the first year i own

Erratic shifting, lead frame sensor causing safety issues and causing truck to not start if shut off. Erratic downshifting at highway speed. Known safety problems with Ford and needs to be fixed. Significant loss of power and lose dashboard data. Issue starting to happen more frequently, almost every time driven
