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.

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.

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.

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.

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!

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

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

- Bridge City, TX, USA

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.

My 2015 Ford F-150 truck has had multiple issues related to performance issues, with only 80,000 miles on it. I have had issues with it losing power while driving, both with and without towing a trailer where it just powers down on the highway from 70-75 mph down to 40-50 mph in traffic. I usually just have to pull over, turn the engine off and then turn it back on and everything runs normal. It is currently at Phil Long Ford in Colorado Springs, CO, having the short block and driver side cylinder head replaced at 80,000 miles because it was smoking out the exhaust and they determined that it had coolant leaking into the #4 and #5 cylinders. This is after it had a completely new engine installed at 75,000 miles due to coolant leaking into the 3# cylinder and causing severe damage to the engine. It was in the repair shop from August 2023 until late December 2023 because the engines were are backorder. The Passenger side cylinder heads are currently on a 13 month backorder according to the dealership, which is why they are only replacing the short block and Driver side cylinder head this time, after only 5,000 miles on the replacement engine. I have also received multiple recall notifications regarding this vehicle, the most recent of which was on 4/22/2024 for #24E03 POWERTRAIN CONTROL MODULE SOFTWARE UPDATE, none of which have been repaired during the multiple times and extended durations that my vehicle was at the Ford dealership for repairs. Two recalls existed and should have been repaired when my vehicle was at the dealership between August and December of 2023, and the most recent recall shows "No Remedy Available" for a PCM Module Software Update?

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.

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.

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.

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.

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.
