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

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.

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.

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.

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.

Analog speedometer is at 55mph while vehicle is stopped. It does not read correctly but increases as speed increases.

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.

Transmission body failed, losing power while driving down road. Like it lost all power. Why would this happen to a one owner with low miles! now we have to pay over $3,000 to have repaired. I’ve seen many complaints about the same issue. Ford needs to own this problem and fix the faulty parts.

Transmission changing gears on its own while driy.

While driving truck on road at approximately 45 mph, truck suddenly and without warning shifted into first gear. After the sudden downshift, the truck then recovered normal shifting for the remainder of the drive. This is the third time this has happened in one year. The first time it happened, I was towing an empty small lawn trailer on a secondary road, with truck in "tow" mode. While descending a hill in a sharp curve, the truck suddenly down shifted to first gear, remained there for a few seconds and then started shifting normally. After this happened, when trailer was unhooked, the display continued to show that a trailer was attached to truck for several days and then the display went back to normal. The second and third time this occurred, there was no trailer attached, and truck was in normal driving mode, and there was no warning, wrench, or check engine lights visible on the dash display before or after the downshift happened. Fortunately, up to this point, I have been able to avoid crashing the truck during these downshifts, but I feel this is a very dangerous and serious safety concern to myself and others. I have contacted the local Ford dealership twice regarding what to do about this problem. Today was told to "monitor" it, that they were booked for weeks ahead, and suggested I may want to go to another dealership. After the second time it happened, I inquired about paying out of pocket for any software update that may help with this problem and told that since my truck was not shown on a recall, that it may make the problem worse, and advised they could not do it. It was also suggested that with no lights on dash display and it being a random occurrence, it would be difficult and expensive to figure out. The vehicle is available for inspection at any time.

6/25/24 I put my 2015 f150 in reverse and gave it just a little acceleration and it immediately accelerated fast crossing the street and hitting a utility pole totaling my truck. I did some research on a Ford forum an saw where othe people had had rapid unexplained acceration. One person said it was because of a faulty accelerato pedal positon also known as app. My safety and anyone walking or driving by my house were greatly put at risk. The problem has not been reproduced or confirmed by anyone. There were no warning lamps or messages. This nightmare came out of nowhere.

I was driving approximately 65mph when my transmission suddenly dropped into 1st gear and my rear tires locked up causing the rear end of my truck to swing out. This is the same issue that the 2014f150's have been recalled for. There were no warnings that this was going to happen. The event was sudden and unexpected. Fortunately I was able to gain positive control of the vehicle and get us to safety. The vehicle has not been inspected by anyone and is currently sitting in a mechanic shop parking lot. Luckily this happened on pleasant summer day with optimal driving conditions. Had this happened in the winter months I am uncertain we would have been so lucky. My concern now is that I am going to have the repairs done and the truck will repeat the problem.

Put truck in reverse and backed up. Then put gear shift into drive and the gear got stuck in neutral and won't budge. A Ford recall for 2014 was issued the same day but I believe based on this same issue, 2015 models need to be included in the 6/25/2024 recall also.

Without any warning signals or indications the fan blower has stopped working. It became a real safety hazard when I needed to defog my windshield and there was no air flow coming out of my vents. No warning, no signal. My windshield had fogged over and I had zero ability to defog due to not having any available airflow. Major safety issue!!.

Rear sliding glass window track falling down. It happened approximately 2 months after I bought the truck. I believe it is just designed badly for a sliding window track.

Lead frame needs replacing. Same issues as the TSB 16-008 and the 16n02 dealer bulletin for 2011-2013 models. This should be extended to later models. Diagnostic code po720.

The door latches freeze during cold weather and prevent me from closing and latching the doors. Ford has previously attempted repairs to my vehicle under customer satisfaction program 20m04, but the repairs have not worked. To further exacerbate the problem, Ford has told me they won't do any further repairs unless they can replicate the problem, but I live in the mid-atlantic and the weather is not cold enough to reliably replicate the problem.

Oil pan leaking due to having a plastic oil pan.

Rear driver's door lock froze and wouldn't lock. Upper lock/latch latched on rear driver's side door, but lower lock/latch froze and wouldn't latch/lock. Had to drive to work with the lower lock not latched and wait for weather to warm up for latch/lock to release. Problem happens every year when the weather gets cold.

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.

The rear window defrost caught fire and made a loud bang noise and shattered the rear window.

Last year while camping. I pulled into our camping spot. When I put my f150 into park. The right passenger door lock popped up and the door opened all by itself. I got out of the truck to shut the door but it would not close. After having my kid pull and holding the door knob up from inside. The door finally closed. But I did it again later on in the trip. It sounds like the same recall that is on other 2015 f150. The dealership here in marysville ohio states that it not a recalled item. They want to charge me $600 plus the fix the kinked wire. I refuse to pay to have it fixed because it sounds like a recall. So the vehicle just sits in my driveway.

Moon roof failure.

Panaramic moon roof collapse into cab, passenger side, when closing during rain event.

Vehicle has a catastrophic design flaw. If water enters the led bliss tail light assembly even in small amounts for anreason, including due to manufacturing defects, minor damage such as a crack, e treme wet weather, or wear and tear of seals, then numerous electrical failures occur of the entire warning system. This includes not only the tail lights, and blind spot backup and cross traffic systems, but catastrophic failure of all dashboard door and window controls. The vehicle cannot be easily unlocked including with remote, climate and accessories cannot be controlled. They vehicle can barely be operated and great expertise and expense required to return the vehicle to proper service. This has happened twice to this vehicle in 2022. Both times it was from minor damage to the taillight lens. Water entered the connectors for a network system which is critical to numerous vehicle safety and critical systems which are completely digital. The part required replacing is available only from a dealer as an oem part and cost $500 plus labor. Research shows this is a widespread confusing problem, which renders high end models nearly inoperable with uncontrollable systems other than basic engine functions and subjecting consumers to great inconvenience and expense. The manufacturer does not appear to have offered recall services and only will repair or replace if the item fails under warranty. Under any interpretation this problem is a gross failure in engineering and safety. What other vehicles with a minor taillight problem have failure of a majority of systems? so many codes are thrown that the average technician and consumer must bear great expense to repair for diagnosis, and then replacement with extremely expensive parts only available from dealer.

We are not sure what component or system failed or malfunctioned. The truck is available at this time for inspection, there wasn't much left of the truck after it caught on fire. The passengers in the truck were in danger, because they didn't realize the smoke they were smelling was coming from the truck they were riding in. It was not until one of the passengers said his arm was hot, it was then they realized the truck was on fire. The fire seemed to have started under the seat. I am not sure what caused it. There were no warning lamps or messages prior to this incident. The vehicle has been inspected by the insurance company, in which the truck is a total loss. The sheriff office and fire department were on the scene.

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.

The o ring on the transmission cooler lines failed causing a loss of transmission fluid. This was hollered by a failure of the lead frame. There was a recall issued for the 2009 - 2014 model years for this problem. It affects the 6r80 transmission and the 2015 model year has the same transmission.

Hitch receiver cracked along input joints. Occurred most proximal portion between the chain connection openings.

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.

Panoramic sun roof sticks or wont open. I went to open it and heard a crack. It looked like the arm cracked. I taped it up because of the rain and now I am trying to fix it myself before the rain starts again. It has had many issues since I bought the vehicle brand new in 2015. I have never asked anyone to look at it because every experience I have had with this truck at the dealership has been very bad. The sunroof has been broken for about 9 months now. I found an online Ford forum as I was searching on how to repair this and found out there are many more of us with the same issue. That is how I learned about this website. I never knew I could report an issue, and there have been many with this truck.

A mechanic confirmed the truck has an issue with the speed sensor. On the daily, the truck will experience shifting issues, gets stuck in 3rd, and will not go past 5th. I have to turn off the vehicle and restart and it resets. I've read this is a known issue, and f150s for model years prior to and after 2015 have been recalled for this same thing. I also believe there are already a significant number of complaints for the 2015 model year for this exact issue. Please issue a recall.

I had the recall on the door/latches done in December 2021 and here we are again and the door latches are freezing. The door either won't unlock and open or if it open then the door will not shut and I have had to drive holding the drivers door closed. I have had Ford look at it and they kept the truck over a cold night and they saw the issue. They have told me to replace the cables and door latch which parts and labor is 800. 00. This to me is crazy because it's a known issue and me spending 800. 00 is not a guarantee they won't freeze.

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!.

Many many times have had an issue with the vehicle turning off in the middle of the road. There is no check engine light to take to a dealer to diagnose. I could be at a red light, waiting to turn, it turns off at any moment. I’ve researched hours as to what it could be, many people have the same issue with no solution. It is absolutely unsafe.
