Engine And Engine Cooling Problems of Ford F-150 - part 2

The transmission needs to be rebuilt/repaired with 162k miles. A member of my family also has a 2017 Ford f150 with the 10r80 transmission and theirs just went out at 92k miles. Also, the cam phaser issue on the 3. 5 eco boost happened to this vehicle as well. Now I need a new transmission and theirs cam phasers, timing chain, etc replaced on the motor on an 8 year old truck. These are known issues to Ford as they have changed the parts that failed with a newer, better version.

My 2014 Ford f150 truck went into “limp mode” last week. A wrench showed up on my dashboard, my speedometer didn’t function, and it sounded like the transmission was “winding up” if I tried to accelerate. After hitting “ok” to remove the wrench and restarting the truck a couple of times, my check engine light illuminated. I was driving at about 40 mph when this occurred and it was a scary moment. Luckily I was able to keep my truck under control and drove very slowly back home considering I was less than 4 miles from my home. The truck went into a Ford dealership in 2024 for the “transmission recall” in which the only thing I noticed different was that I couldn’t see the digital shifting of the transmission on the screen anymore and they “killed” my battery. I still had issues every so often with power loss or the transmission shifting down abruptly, but it wouldn’t throw a code. Last week it threw a code. P0720 to be exact, the reason for the transmission recall in the first place. There was no fix done with the recall and it made it so that I had to watch my rpm’s to track my transmission shifting. This is extremely concerning especially since I was having the issues prior to a computer reprogram and it wasn’t addressed. I have also seen that there’s yet another Ford transmission recall that could affect my truck considering it was assembled in June 2014 and fits the transmission 6r80 that needs fixed. Could someone please help? thank you.

On 4/22/2026 while flat towing this vehicle behind my motorhome, it burst into flames. The trip began in [xxx] . Driving south on xxx, I stopped about 120 miles later at a rest stop near xxx. I did a complete walk around inspection. There were no issues, everything looked fine. We continued on and about 20 miles later another vehicle driver was telling me frantically to pull over. I looked at my rear camera and saw the Ford was smoking. This was not due to an improper neutral tow setting. The truck would have burned in the first 20 miles. I have towed this vehicle many times. I know the importance of doing it properly. , thankfully there was a good place to pull over. I tried to extinguish the fire with my extinguisher but it was too hot. I was unable to disconnect from the motorhome. Both are a total loss. I think of all the places this could have happened and how trapped we could have been. By the grace of god, nobody was injured. Yes there is a police report and an insurance claim. There were no warning signs. My braking system runs on its own battery so there was no draw on the Ford battery. Ford did an update on the computer the night prior. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

*what component or system failed or malfunctioned, and is it available for inspection upon request? -the vehicle downshifts suddenly and hard-shifts down on its own. It is worriesome as it randomly happens and oftentimes at high speeds. Yes it is available for immediate inspection. Was your safety or the safety of others put at risk? -on more than one occasion the vehicle has suddenly downshifted causing a hard noticeable jerk at random speeds. I am worried that at higher speeds it can lockup and cause a serious accident with my kids in the car. The problem been reproduced or confirmed by a dealer or independent service center? -I have taken it to Ford on several occasions in the past but said they didn't notice anything, but I recently took it again and explained the downshift and hard-shift again and now they told me it needs a full transmission replacement that would cost close to $8000 dollars. The vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -the vehicle has been taken to Ford on multiple occasions but they did not find any issues at first. I took it again as it has happened more often and now they tell me it requires a full transmission replacement. *were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -the issue first appeared last year, I took it and told them that it had a suttle jerk and asked them to inspect and if there were any recalls. No warning lights. *I am seriously concerned for my safety, it is my only good vehicle and worried it can cause an accident with my kids in the vehicle.

See attached document for complaint.

Diagnostic trouble code (dtc) p0720 stands for “output speed sensor circuit malfunction. ” it is stored when the ecm/pcm/tcm perceives a problem with the output speed sensor or its circuit. If, for example, the engine speed and input shaft speed are at a certain rpm but the output shaft speed is erratic or not what the computer expects, p0720 will be stored. There may also be a p0500 code stored on some platforms. T.

Dash said look for safe place to pull over. When turned engine off, it would not start again. Had to wait hours to get it towed to dealership. Been there over 5 weeks and they still don't know what's wrong but suspect hybrid battery problem. Only about 21k miles and 18 mo old. No loaner provided.

The cam phasers failed somewhere between 60,000 - 70,000 miles. It is a defective part that was subject to a customer satisfaction program in 2020 or 2021 but we purchased the vehicle after this. Now, Ford is saying that we need to pay to replace the cam phasers and the timing belt. It was quoted at $5777. 62, which is a significant repair cost. Also, this shouldn't happen with this part and I am seeing everywhere that other consumers are having the same problem, including some at the current dealer we are working with. Any help is appreciated.

While driving my vehicle (2019 Ford f150), it suddenly came to a complete stop. The engine shut off and the steering wheel locked up. While in the middle of a roadway, I had to quickly throw my vehicle into park, turn it off and back on. At that point, it was running again and I was able to safely get it to a dealership where it was inspected for an issues. There were no warnings, alerts or messages on my dashboard. The dealership confirmed what had happened. It was due to the electronic steering system failing. They fixed it and so far there has been no issues. This is not the first time I have heard of this happening and after researching, it appears it is more common than not. I believe, because of the risk of this vehicle unexpectedly and suddenly stopping on any roadway, a recall should occur. I could not imagine what would happen if one of my loved ones had been driving and a serious crash occurred.

My 2019 Ford F-150 was subject to safety recall 21b10. In June 2021 the dealer documented the cam phaser issue but could not perform the repair. I received the recall notice in October 2021 and step one of the recall was completed in December 2021. In June 2023, still within mileage coverage and under warranty, I returned with the same complaint. The dealer acknowledged the problem and ordered parts explaining that they would take a very long time to come. I was never contacted again. In April 2026 my vehicle has sustained damage to the timing chain, guides, solenoids, cam phasers, and tensioners — all components directly related to the unrepaired recall defect. Ford has offered only partial goodwill coverage, leaving me with a $1,600 balance for damage caused by an incomplete federally-mandated recall repair.

Our truck has been experiencing downshift to a lower gear and the powertrain warning lamp wrench symbol in the instrument panel cluster comes on. This has been happening from about 4/1/2026 and ongoing.

Exhaust manifold bolt broke cause extra heat coming from that broken bolt cause the crank shaft position sensor wires to melt cause the vehicle to stall while driving down the road and it not to restart just cranks and throws the code for crank shaft position sensor.

Grinding noise on startup. Goes away after warmup. Ford dealer just reported that I need a $6,500 engine repair. I’ve owned this truck since brand new in 2019. Always have done routine maintenance. This clearly is a quality issue.

I own a 2023 Ford F-150 lightning, with 48,200 miles and 2. 5 years of ownership. Recently, my truck began displaying a “powertrain / reduced power” warning while driving, and the air conditioning stopped producing cold air. The dealer scanned the vehicle and found dtc p0534 – a/c system charge loss. Further diagnostics indicated that multiple vehicle modules may require reprogramming and software updates. The dealer stated they need to evacuate and recharge the ac system, add dye, and remove front trunk components to locate the leak. This ac system is part of the high-voltage battery and edrive thermal management system, meaning that failure of the hvac system affects battery cooling and powertrain performance. Loss of cabin cooling is a symptom of a thermal system malfunction, which can lead to battery overheating, powertrain derating, and reduced driving performance. The combination of unexpected reduced power and loss of cabin cooling creates a safety risk, particularly during highway driving, merging, or situations requiring acceleration. These failures occurred at relatively low mileage and are associated with the high-voltage ev system, which should be functioning properly to ensure safe vehicle operation. I am submitting this complaint to report a potential safety defect with the 2023 Ford F-150 lightning affecting the battery thermal management, high-voltage ac system, and edrive components, which can result in sudden power loss and compromised vehicle safety.

Oil pan leaks. The f150 just crossed 70,000 miles. At just under 60,000 miles the truck had what the Ford service tech described as a weap from the oil pan. He said it was a costly repair so just to watch it. At 65,000 it was a steady drip when the oil was warm. Now at 70,000 the Ford dealer is recommending a replacement. What I have learned is this is a common failure on 2015 to 2017 f150s with the 2. 7l engine. I suspect this was happening earlier but the Ford dealer was relucant to bring it up as it would have at the time been covered under warranty. I have also now learned Ford is on its 3rd TSB for resolving this common leak at the oil pan. Hopefully this will warrant a recall response from Ford. From research this is a very common failure and engine damage will occur if the leaking oil pan is not repaired. Please investigate as I suspect there are numerous complaints. Thank you.

"my 2015 Ford F-150 is experiencing an intermittent, complete loss of the output shaft speed (oss) signal within the 6r80 transmission lead frame. While driving at speed, the speedometer suddenly drops to zero, the 'wrench' light illuminates, and the vehicle performs an unintended, harsh downshift into a lower gear (limp mode/3rd gear). This creates an immediate safety hazard of rear-wheel lockup or a sudden loss of acceleration in traffic. I took my vehicle to a local repair shop where they could not duplicate the fault. I then called my local Ford dealer who informed me unless it would duplicate the fault or show a code they could not repair the vehicle due to it being against warranty policy.

After a crash into a tree on the passenger side the airbags deployed and the truck immediately caught fire and the doors locked and would not open for any reason. The only way I was able to exit was busting through the front windshield. Had I been severely injured or knocked unconscious the outcome of this would have been much different. The truck burned to the ground in 11 minutes. It has been inspected by the police and awaiting insurance representative to inspect. There were no warning no recalls regarding a crash that would lock the doors and not allow me to exit.

My vehicle keeps downshifting randomly at highway speeds and will also not shift out of 1st or 2nd. Rear tires keep locking up. 1. Pcm 2. I have a hard time keeping vehicle in control 3. Yes, active recall can't repair until July 4. Yes, it has been inspected 5. Yes, check engine and wrench light.

My truck is a 2025 Ford f150 stx with 5,900 miles on it. This truck was purchased new at river city Ford in lavalette, wv the component in questions seems to be involved with the turbos and more specifically the wastegate that attached to the turbos. Also, yes, it would be available for inspection. I am unsure if it is a true safety concern as Ford says it is not and it is normal operation. However, with it making the rattling sound that it does I would believe that it could cause damage or that it's not normal operation. Yes, the problem has been confirmed by the dealer on 2 visits now but Ford refuses to do any type of repair as they say this is normal. It has only been inspected by Ford technicians the problem appeared over a month ago and is still happening every time I drive the vehicle.

. 2016 F-150 Ford truck. Purchased from a used car dealership. While driving the truck on a freeway at about 40 mph, accelerated to 55 mph and changed lanes. Engine went into limp mode. Check engine light flashed. Started to deaccelerate. Moved vehicle over to shoulder. Fault codes: p0340, p0344, p0365, p0369. This truck has a 2. 7l ecoboost engine. Mileage is about 130,000. Two mechanics from different companies evaluated and found timing chain broke and sheared the keyway on the crank shaft where the timing sprocket is located. There was not prior warning to indicate any issues.

I’ve had the transmission replaced along with the torque converter when both failed less than a year ago. The transmission and the torque converter are now doing the same thing it was doing prior to the replacement. The transmission slips in 4th, 7th and 8th gears. The torque converter whines loudly. Ford will not fix the issues with these transmissions without a hefty out of pocket fee. It’s become very well known that all of these 10r80 engines/transmissions are a major problem that Ford is not remedying. If this transmission gives out when I’m on the interstate it’s going to cause a major wreck. I live in the mountains, so a bad transmission can quickly turn into a deadly accident. These transmissions need a permanent fix, not for us owners to continue paying thousands of dollars for replacements or rebuilds. This is Fords problem.

The contact owns a . The check engine light illuminated, while driving, the vehicle shifted to a lower gear unexpectedly and the turbo began to make a noise. , the rpm's rapidly increased. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unavailable.

My transmission jumps or skips or sometimes simply doesn't engage between gears, resulting in upshifting for a slow performance when I need to cross a busy intersection, or staying in low gear and revving up when trying to get on the highway. Some days it works okay, some days it doesn't; but rarely does it work right.

Loss of engine oil pressure. Just had engine replaced with used 6 months ago for the same issue. This new to me motor had 40k miles on it. So two motors under 121k miles oil pressure failure. Causing total engine replacement.

While driving my 2021 Ford F-150, the vehicle suddenly began shaking, lost power, and shut off completely while in motion. This created a dangerous situation as I was left without acceleration while driving. Prior to the failure, there were no major issues with the vehicle. After the engine shut off, a battery warning appeared, but the battery had been in good condition and less than a year old. The vehicle would not restart and had to be towed to a Ford dealership, where it has remained for over two weeks. Independent mechanics and the dealership have both indicated the issue is related to the fuel system. I later discovered this matches an active recall for the low-pressure fuel pump. Despite this, I was informed there is currently no remedy available for the recall. The vehicle is still at the dealership and has not been repaired. I have not been provided with a loaner or rental vehicle and have been left without transportation for work or to care for my children. I have also been asked to pay out of pocket for towing and battery replacement, even though the failure appears to be related to a known recall issue.

Vehicle information 2021 Ford F-150 powerboost VIN: [xxx] complaint description while driving approximately 70 mph on a highway, my 2021 Ford F-150 powerboost suddenly displayed a “stop safely now” message and immediately lost propulsion. The engine shut down without warning while I was in active traffic. After the shutdown, the vehicle automatically shifted into park and would not allow me to shift into neutral. This left me unable to move the vehicle out of a live traffic lane. I was forced to shut the vehicle off while still in a dangerous roadway position. This incident created a serious safety hazard, as I was traveling at highway speed and could have been rear-ended due to the sudden loss of power and inability to move the vehicle. This issue appears to match Ford technical service bulletin (TSB) 23-2317, which describes “stop safely now” warnings, no-start conditions, and gateway module (gwm) software faults. This indicates a known defect that can cause sudden loss of propulsion. A claim has already been opened with Ford motor company under case number [xxx], and the vehicle is currently at a Ford dealership for diagnosis. At this time, the issue has not been resolved. This failure occurred without warning and presents a significant risk to driver safety and others on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2025 Ford F-150. The contact stated that while starting the vehicle, the engine revved, and while idling, there was a knocking sound coming from the engine. The vehicle was taken to the dealer and was diagnosed with bearing damage caused by a defective connecting rod and rod bearings, which caused the engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact researched online and became aware of NHTSA campaign number: 25v344000 (engine and engine cooling); however, the VIN was not included. The manufacturer was informed of the failure by the dealer; however, the contact had not spoken with the manufacturer. The manufacturer opened a case for the failure. The failure mileage was approximately 1,000.

At 68000 miles I noticed the engine is burning through oil at a rapid pace. A quart of oil a week is bad. If this happens to someone who doesn't keep up with their vehicle, and check it regularly it could be a devastating outcome. It's time Ford fixes this issue.
