Engine And Engine Cooling Problems of Ford F-150 - part 1

While driving, transmission will randomly shift gears from a higher gear all the way down to first gear regardless of travel speed. When traveling at highway speeds, this results in a loss of traction on the rear wheels, causing fishtailing and a momentary loss of control. This problem is getting worse, and is the result of a known defect in the transmission speed sensor that has been acknowledged by Ford in previous recalls. The previous recall repair attempt by Ford involved a dealer reset of the computer rather than replacing the defective sensor, which did not fix the problem. The frequency of this sudden downshift is approximately 2-4 times per ten miles driven.

This is a continuation/escalation of NHTSA complaint 11689917. My 2021 Ford F-150 has experienced repeated fuel-system/electrical fuel-pump failures. The vehicle previously stalled and later cranked but would not start, returning code p0627 “fuel pump a control circuit / open. ” the in-tank fuel pump was replaced at owner expense for approximately $1,400 at an independent service center in September of 2025, but the repair did not permanently resolve the issue. The vehicle has now again lost fuel pressure/propulsion while traveling approximately 50 mph on a two-lane highway in a similar manner to prior failures. I was able to get the vehicle off the roadway, and it required towing back to my residence. This is approximately the fourth or fifth fuel-related failure, including stalls at low speed and non-start conditions related to fuel in parking lots. The symptoms appear consistent with Ford/NHTSA recall 25v455 / Ford recall 25s75, but my VIN was not included in the affected group. I am concerned that the recall population may be too narrow or that the remedy does not address the full defect pattern.

Hard downshift caused my truck to slow suddenly and became very hesitant where the vehicle behind me had to slam on their brakes. I then pulled over when it was safe, turned the truck off and then attempted to turn back on with no success due to the shift indicator no longer lighting up. This matches up with the current recall for this particular vehicle.

Cold start rattle lasting a second or more. Ford dealer diagnosed it as being bad cam phaser (TSB 23-2143). This is a very common issue with 3. 5l engines from 2017-2020 - well documented on forums and youtube (even by Ford technicians). I contacted Ford to see if they would assist in covering cost (my vehicle was a previous fleet vehicle and sold certified used in Dec 2020 with warranty running out in Dec 2025). Ford had several csp's related to these engine and model years (21b10 and 21n03). Ford says my vehicle is not affected by these two csps and that is why coverage is denied. Dealer did determine my vehicle qualified under both csps based on information from the csp's (make, model, build plant). My vehicle is affected by known bad parts, Ford redesigned vct. Per Ford technicians, the new vct design is the only long term fix (pcm reflash and replacing with original vct parts are not). How can a TSB (23-2143) cover my vehicle when the previous csp did not - for the same issue. Ford is refusing to assist customers cover cost to replace of known poorly designed parts (why would they redesign if they didn't know)? Ford does not include my vehicle in the csps though it matches criteria - Ford possibly drastically understated the number of vehicles affected by these csp's. Dealer says mine is affected by this but frod doesn't include my vehicle. This should be a full recall (not time limited under csps) as it can cause the vehicle to not start when auto stop/start is enabled (middle of 5 lane highway in atlanta metro area rush hour). Failure of cam phasers can force vehicle into limp mode reducing ability to operate vehicle . Ford is well aware the parts are faulty and an integral part of the engine, why would they redesign if they were not faulty?.

Ford has acknowledged the defect (recall 26s28). · my truck experienced the dangerous downshift and wheel lockup. · Ford has no fix available until June 30th, leaving me without a safe vehicle. · Ford is refusing to provide a loaner or rental. The wheel locked on me and causing the vehicle to be uncontrollable, in wet condition. Causes a near fatal accident. I do have a dash camera recording to prove my case.

I was getting on the highway in 7th gear and the truck shifted to 1st gear. The rear end locked up and my vehicle skidded out of control. Luckily there was no one around and I did not contact another vehicle or a road barrier.

My 2020 Ford F-150 5. 0l coyote v8 had its engine replaced under factory warranty on 4/30/25 by an authorized Ford dealer. The replacement engine was installed with my original 50,000 mile fuel injectors reinstalled by Ford's technician — I was not informed new injectors were not included. The vehicle is now diagnosed with a failed direct fuel injector causing a cylinder 3 misfire at approximately 10,000-12,000 miles on the replacement engine. Additional injectors show signs of imminent failure. The shop also documented the replacement engine running 2 quarts low on oil at only 10,000-12,000 miles of service. This level of oil consumption on a recently replaced engine is abnormal and unexplained. The safety concern is twofold. First, a vehicle running chronically low on oil due to abnormal consumption on a replacement engine risks catastrophic engine failure without adequate warning to the driver. Second, misfiring cylinders affect vehicle driveability and create unpredictable power delivery that constitutes a safety risk particularly at highway speeds. Symptoms including rough running and the check engine light first appeared in November 2025. The vehicle has been at an authorized Ford dealer for diagnosis since may 2026. Ford customer relations has declined goodwill assistance despite the failure occurring on components reinstalled by Ford's own technician during a warranty repair, symptoms originating within the warranty window, and the vehicle being only 8 days outside the 12-month parts warranty expiration. I am requesting NHTSA investigate whether Ford's practice of reusing high-mileage fuel injectors during engine replacements under warranty constitutes an unsafe practice, and whether abnormal oil consumption on replacement engines represents a systemic defect.

The truck rapidly accelerated while I was slowly rolling into a parking spot with my foot on the brake. The harder I pushed the brake the more it seemed to accelerate. I luckily avoided hitting anything. I forced the gear shifter out of drive into park. No warning lights or messages. I contacted 3 Ford dealerships and all said they haven’t heard of this nor do they think they could identify this problem if I brought it in.

I've sent earlier not sure if it went through transmission dropingvout of gear at any time putting my. Life in danger, and family, hope I don't end up needing a lawyer if a major fatality happens.

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.

The engine started running loud and making a knocking noise. Took it to the dealership and they said it needs a new engine. Regular maintenance performed by Ford. There were no warning lights that came on prior to the engine failure. They say the engine is on back order.

I have reported the same exact issue that Ford recalled April 14,2026 with my vehicle. I almost had an accident by it changing from automatic to the gears & it comes to a sudden stop when it do it. I guess someone or me gonna have to lose a life before some look at my issue. It showing a recall was on my truck in 2019 before I brought the truck. The recall has not been done on my truck. Please help b4 someone get hurt. Thank you.

Transmission shifts eradicate, jumps into gear (hard) motor rpm raises high as transmission actually jumping , not smooth shifting into gear .

Check engine light coming on and off with an emissions code, transmission shifting really hard.

*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.

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.

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.

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.

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.
