general problems of the 2015 Ford F-150 - part 2

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.

The engine while operating at normal speed loses power to a rough idle and is remedied by putting the vehicle in park and restarting the engine. The engine never fails to start after restarting, but could fail at any moment, short or long term.

I cold started the engine from inside the house and when I opened the back passenger door there was smoke coming from behind the rear seat in the back area. I couldn’t get to where the smoke was coming from but from the smell it was wire related. I quickly went around to the driver side and turned on the truck and quickly turned it off. About 10-30 minutes later the ring camera showed the rear window of my truck shatter due to this incident in which I was informed that the rear auto defrost turns on due to a malfunction. I put a claim through my insurance and got the window fixed but I am still worried that this issue may happen again. I hope that by informing you of this situation going forward you can help others including myself be aware of this problem and how we can fix it. Thank you for your time and I like to say I love Ford trucks and plan on staying a loyal customer.

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.

The lead frame on the 6r80 transmission is faulty causing a sudden stop in operation while the vehicle is moving.

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.

I was driving at 65 mph when my 2015 f150 shifted into 1st gear. I started skidding sideways and almost flipped but was able to run through the gears quickly and got it into neutral. This has happened a few other times since the initial incident. I constantly receive codes related to lead frame assembly issue: p0720, p0721, p0722, p161b, etc. I am in desperate need of a new lead frame assembly so my vehicle does not crash on the highway. Thanks!.

Twice now in the past 2 weeks I was accelerating from a stop when soon after my truck shifts from 4th to 5th, it’ll slam back down into 2nd gear. Both times my rpms spike, obviously, and my tires briefly screech. Then the truck just shift back up and seems completely normal. There was zero indication of any issues prior to either of these incidents. One of the times, I had my wife and two toddlers in the truck. It was lucky I didn’t lose control either of the times. From the forms that I’ve read, it sounds like I have a faulty transmission range sensor or may need a software update. I have not yet had a dealership officially diagnose my vehicle.

The timing belt/chain is failing on F-150 trucks and multiple people have sent in issues. I think from 2015-2018. It looks like you are already looking at other Fords with same issue. What I was told is that there could be sudden stalling: if the timing is thrown off or the chain snaps, the engine cuts out instantly. Losing power steering and engine power while driving in traffic creates an immediate crash hazard. Severe misfires and power loss: a slipping chain causes rough idling, violent shaking, and an inability to accelerate which happened to the truck. Due to this I had to get mine fixed in June of 2024 I have attached the invoices. I tried to upload invoice but said there was an error.

Throttle body failure approx every 45,000 miles. Bought F-150 new, now driven it approx 135,000 miles. Failure occurs when driving a various speeds, incl 75 mph. Engine shuts down, complete loss of power. Dangerous situation; safety at risk! unexpected & random loss of power - w/ passengers aboard - in various traffic situations. After engine shuts down, restarts, then randomly shuts down until a new throttle body is installed. First throttle body failure repaired (=throttle body replaced) @ Ford dealership in price, ut. 2nd failure repaired @ Ford dealership in hamilton, mt. Both covered by extended warranty. 3rd failure repaired 5/21/24 @ hamilton, mt @ $324. 55 personal expense. Check engine light warning occurs.

The truck only goes through 1 through 3 and then when it shifts into 4 it doesn’t go anywhere and it throws a bunch of service codes that just go away when you turn the truck off it has dropped from 6th gear to 3rd and locked the tires up and spun me out almost causing me to wreck the truck.

I connected the 7-pin trailer wire of my 16' tandem axle enclosed trailer with electric brakes to my pickup. I checked the lights on the trailer. All functioned correctly. I got into my pickup to drive. The integrated trailer brake controller was smoking and getting hot. No error messages popped up on the dashboard. I pulled the fuse for the trailer brake module to prevent the integrated trailer brake module from melting or catching fire. Upon searching the internet, this appears to be a problem with my model year (2015 F-150). Ford dealership re-programs the trailer brake module. This needs to be addressed before the brake controller fails and could potentially catch fire. It also could cause an accident, because the electric trailer brakes will lock up or cease to engage.

Al darmarcha mi camioneta no dio marcha creei que la vateria estaba baja pero no dio marcha solo encendieron las luces del tablero brake system y electric park brake no damarcha se bloqueo por completo.

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 owns a 2015 Ford F-150. The contact stated that while driving 60 mph on several occasions with or without the cruise control feature activated, the transmission unexpectedly downshifted to first gear, and the rear wheels locked up. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the transmission circuit board and valve body assembly needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 105,000.

The contact owns a 2015 Ford F-150. The contact stated that another vehicle had backed into the contact's vehicle which cracked the lens cover on the rear cross traffic system. Once the lens cover cracked, moisture began to enter the lens cover which caused both the window defroster and the power windows locks to not operate as needed. The contact stated that several warning messages including the "cross traffic collision", and "tail collision" had appeared on the instrument panel. The contact called several dealers in his area and was informed that the part to repair the vehicle was on back order. The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 90,000.

Regarding: 2015 Ford f150 with 20,000 original miles on it. -made 1st report with NHTSA. Gov as well as Ford. Com back in June 2023 about the vehicle throwing codes for anti-lock brake system and communication loss of ecm/pcm. As well as, the system not allowing the brand new battery to ever be fully charged. -upon 1st reporting these issues, the vehicle was placed into the "friendly Ford" service center in crosby, TX to be worked on and issues fixed. $1,376, later, we were contacted by the service center to pick the vehicle up, saying issues were now fixed. (their prognosis: auxillary transmission pump replacement 6/19/2023) after picking vehicle up, all seemed to be running correctly. Until, the vehicle decided to do the exact same thing again. . . No charging the battery, not starting engine, turning itself off, ect. Just got the vehicle out of the same service shop,, this time them claiming that it was now the transmission control module that needed to be replaced. This service trip costed $1490 (july27, 2023). When the service worker went out to bring the truck around for us to leave, he had to attach a battery booster to the battery, just to be able to start the vehicle. . . . Ding< ding< ding!! not fixed. . . . . . Right ?! correct!! it is not!! so, here we are again (07/29/2023) with the code reader at autozone saying "anti-lock brake system/ ecm/pcm (u0151-00 and u0100-00). Battery tested to be in good working order, as well as the entire starting system, itself is in complete working order. And still our problem persists.

The truck shuts off at red lights. This is not the feature for gas saving. The engine completely dies. This is extremely dangerous. You are stuck in running traffic until it starts back up. The Ford dealer said there are no service bulletins and they've never heard of it. But the f150 forum is full of examples, and Ford is not aware or fixing the issue. This happens several times a week.

While driving with my family the truck gave several error messages and a check engine light. I pulled over immediately because the truck lost power and the stability control started shaking violently. I was able to safely maneuver out of traffic, but I cannot imagine what would have happened if I was on a busy highway instead of a small side street. Apparently this is an issue that has been fairly common with Ford from what I have seen online. The vehicle is at the mechanic now for repairs. He has determined that the throttle body needs to be replaced.

While driving there is a hard "clunk" sound then blind spot system, cross traffic system fault and see manual alert comes on. Truck loses power and shifts out of d (acts as if in neutral). Has happened about 7 or 8 times now. Very scary situation and can be tragic if this situation happens at high speed. I have done some research and I know there have been recalls for transmission lead frames on older model F-150's. Sounds and feels to be the exact same situation for my 2015 F-150.

I am not sure this is the place for this, but here goes. . My truck dropped my phone connection I tried to reload it, I deleted it and tried to re-install it. The truck told me it was looking for "bt". I called to sync and they walked me thru a few things and said I need an upgrade, I have a 5. 8 and I need a 5. 11 program. My radio is a basic radio, no navigation nothing special. So I took it to the dealer and they tell me I need a apim and the price is off the charts. I am not sure if this all is connected, but I also have problems with the radio controls on the steering wheel on an intermitten basis. I apologize if this is not the place for this complaint but I had to start some place, please advise where I might go from here. I don't feel an 8 yr old truck should be having issues like this already.

Trailer disconnect error. Trailer wire fault error. Resulted in near accident causing trailer brakes to engage randomly at highway speeds.

My airbags deployed while my truck was parked overnight. No known cause, no collision. Also when I put the keys in the truck all my dash lights were on no power steering. The truck is currently sitting at the dealership.

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.

My f150 kept setting alarm off every day or 2 running battery down, took to Ford house, paid $109 to be told they have never seen this problem. Looks like another $900 because my truck computer says it’s always getting broke in to? wow really?? never been broken into by the way!! interior intrusion sensor is to sensitive ( by the Ford houses managers mouth by the way). Does that make sense??.

The contact owns a 2015 Ford F-150. The contact stated that while turned off he observed condensation under the front of the vehcile. The contact stated that radiator fluid was administered but continued to leak from under the vehcile. The vehicle was taken to a dealer where it was diagnosed that there was a six-inch crack on the radiator, where the o-rings and the driver's turbo and radiator needed to be replaced. Additionally, while powered on the head unit did not illuminate. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximatly 125,000.

Rear window defroster was emitting a burning smell (although it was not turned on) and overheated the rear glass causing it to bulge and shatter!.

While driving at speeds between 10 and 55 mph, I lose power and have to try to drift safely to the side of the road. Multiple dash lights come on (blindspot system fault, cross traffic system fault, see manual) and my drive indicator light strobes across all gears prndlm21 randomly. Some of the time the vehicle acts like it is in neutral. Other times it can inch forward at 5mph. My safety is put at risk because I lose all power control while in traffic! I have had it in the Ford dealer shop for more than 6 weeks. It's been in there twice for the same problem and they cannot find a specific problem. Prior to this happening, there were not any warning lamps, messages, or other symptoms. I have had to be towed from the side of the road twice now. Approximately 10 other times, I was able to wait for a period ranging from 5 - 30 minutes and then the vehicle was able to move again.

Good afternoon- yesterday morning I was driving to work and had the defrost on. About 5 minutes later I starting smelling something burning. When I stopped at the gas station I noticed both sides of the rear window were all spiderwebbed/shattered, not the middle automatic one though. Can you please help? I’ve went to a dealership, called Ford customer care and know one wants to help. This has to be a defect, like a short in the rear defrost or something. Update-went to lindquist Ford in bettendorf, IA and service manager 100% confirmed without a doubt the window shattered due to a short in the rear defroster and said he sees this all the time. Unbelievable that this is not a recall. Please see website below https://fordauthority. Com/2017/12/another-Ford-f-150-owner-claims-the-rear-window-shattered-despite-no-impact.

Unsure of time of report but possible electrical issue with rear defroster. White electrical smoke and glass shattered while driving. Smoke filled cabin and was coming from passenger rear seat. Once seat was lowered the smoke was coming from behind the fiberglass so unable to see damage. The two connectors that go to the sliding glass are hanging freely and were sparking when seat was lowered. Rear defroster was on when issue occurred and smoke stopped once turned off. Vehicle has not yet been inspected, awaiting insurance claim. There were no warning signs, messages or symptoms of failure. Incident happened on 09/23/2022 at 7:40 am while driving on interstate.

While driving at posted speeds on open highway and in congested work zones, this F-150 experienced an electronic throttle body failure 5 times between rochester hills, mi and granger, in on 9/13/2022. It happened again on 9/14/2022 in city two way traffic with no shoulder. In each incident, the vehicle went into limp mode with rough idle and had to be completely stopped, turned off and restarted in high traffic, hazardous stopping locations. This happened once before in the mountains in utah, in a construction zone back on 5/02/2021. At that time, the check engine light did not stay on and Ford was unable to find a code. It did not happen again until 9/13/2022. These incidents put me and my family in danger with each episode. Ford is fully aware of this issue, has in the past and should notify owners of the potential issue and continue to make repairs available as a recall or extended warranty service issue.

The contact owns a 2015 Ford F-150. The contact stated that on several occasions, the gear shifter was placed in reverse however, the backup camera failed to operate. The contact stated that the backup camera displayed while in drive. No warning lights illuminated. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were notified of the failure and the contact was informed that there were no recalls on the VIN. The failure mileage was approximately 50,000.

Dashboard blackout while driving.

Moisture in a taillight housing of a 2015 lariat F-150 caused the blis module and wiring harness to short out. The blis module is tied into multiple vehicle systems, and caused the following issues: airbags turned off blis system turned off tpms turned off windows and door locks don't function radio stuck in whatever setting it is in when faulted air conditioning panel and all climate controls turn off during a road trip this happened. I was unable to egress the vehicle until I shut it off. It is summertime so the vehicle, without ac or the ability to control the windows, became very hot. I had kids in the car. Also, without airbags, window, and door control, if I were to crash the vehicle, I don't know if I could safely extract my family. The moisture in the taillight is a known issue, and is covered in gsb 22-7002, but I couldn't find a blis module gsb/TSB. However, the blis module failure is a known issue, and there are multiple diagnostic videos and write-ups describing this issue on youtube and F-150 forums. This is a safety issue, and should promptly be addressed.

Two weeks ago my 2015 Ford f150 died in a parking lot. I drove it in fine, walked into the store, and when I left the store the truck was dead. Battery was good, alternator was good, but would not start. I had it towed to my local Ford dealer. Three days later they informed me that the starter was bad and it was replaced. Two days later I'm driving at highway speed (approx 70 mph) and the truck violently downshifts from sixth to third gear causing the tires to lock up and the vehicle to skid approx 20 ft in nyc traffic. Luckily there was no one close behind me although there were numerous car horns beeped and swerving traffic as I rapidly decelerated. The truck remained in third gear until I moved into the safety lane and the rpms (due to slowing) returned to normal. The instrument panel only displayed a message "contact dealer". I shut the truck off and the turned it back on with no faults indicated and limped it home. Since then the truck has repeatedly failed to start. It will start fine for a day or two, and then nothing when the key is turned. I had it towed to my local service station where the mechanic informed me that the computer code errors indicated that there were multiple errors with the transmission. The soonest that the Ford dealer can inspect is 35 days from now. I see that earlier model Ford f150's had a factory recall for similar transmission problems. My concern is that due to electrical malfunctions within the transmission control module, Ford f150's may rapidly decelerate when the transmission inadvertently downshifts multiple gears causing accidents and possible loss of life.
