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

Driving on freeway 10 speed transmission failed - hard knock and jerk, almost got in an accident. Gears 6-9 dead. Apparently this 10-speed transmission is a known issue, with many technical service bulletins issued, class action lawsuits, and angry customers. Ford refuses to issue a recall and the NHTSA refused to hold them to account. Something is broken - how can Ford make such a known, terrible important component to a vehicle that fails regularly - yet get away with it? I thought the NHTSA was supposed to protect us from these unsafe vehicles?.

Cam phaser rattle, infamous in many Ford models. The 2019 eco boost is very known for this sound and issue, Ford has offered temporary resolutions and assistance before but no permanent fix. This issue affects hundreds of thousand of Ford models and is quoted at a $5,500 job by many dealers. Ford owners are aware of the issue and so are Ford dealers. It is no longer a temporary issue and is long overdue for a recall.

Ford has a known issue with the 2019 f150 eco boost cam phaser rattling. They replaced once and it failed again. They now refuse to repair the fix that should have corrected the initial cam phaser issue. They continue to use faulty parts.

Had the truck 4 weeks from dealer and it was 5 quarts low on oil!! got oil change. Another month passes and it was almost 2 guards low. Took it to shop they can’t find a leak. Another month passers and it’s 1. 5 quarts low again! every month have to put 1. 5 to 2 quarts in it!!! have not even had it 6 months yet! must be a lemon!!!.

Over the years the engine has felt like it was slipping or stalling. It appears to be increasing more. Sometimes it happens while cruise control is on. Today, the engine slipped for a prolonged time, more than usual, and then rpms decreased. Warning sign of a “wrench” appeared on screen and said see manual. I was also unable to put vehicle in reverse. Slips more at lower speeds when accelerating.

While traveling at cruising speed (70 mph) on interstate 95 south, the vehicle suffered a catastrophic electrical and mechanical failure, resulting in an immediate engine stall. The vehicle lost all propulsion. Due to the sudden loss of power, the vehicle could not safely clear the active lanes of traffic, coasting to a stop near an exit ramp and dangerously blocking highway traffic. Upon attempting to restart the vehicle to move it out of harm's way, the vehicle emitted a rapid clicking noise and again stalled out. Because this vehicle utilizes an electronic shift-by-wire system, the total power failure permanently locked the transmission into "park. " the vehicle could not be shifted into "neutral" or "drive" to be pushed safely off the road. This total vehicle failure created an immediate, life-threatening hazard for the occupants and surrounding motorists on a high-speed interstate, requiring emergency police intervention to manage traffic until a flatbed tow truck arrived.

I was on the highway and my truck suddenly decreased speed rapidly. Luckily I was able to pull onto a side road and get to safety but it was extremely dangerous and scary situation. The dealer has confirmed the symptoms fit the issue with the recall. Since Ford does not have a fix for this solution yet until July 1 my vehicle is unable to be driven or repaired leaving me stranded without a vehicle. However, this is a very concerning safety issue and my family could have been severely impacted traveling on the highway.

Excessive oil consumption. I have to check and refill every single week since I drive over 100 miles/day, it is ridiculous how much oil burns. Transmission at high speed acts very erratic, when downshifting is like it doesn't know what do do and when it finally decides to down shift, it kicks so hard that feels like it's going to brake in pieces, even at low speed the shifting is very hard, not smooth at all. Radio carplay is useless, every time I try carplay, it works but I am not able to use the volume, so I have the feature but can't use it.

I experienced a sudden coolant leak on my 2017 Ford f?150 equipped with the 3. 5l ecoboost engine. The Ford dealership diagnosed the issue as leaking turbocharger coolant lines. The coolant was leaking in the turbo area and dripping onto extremely hot exhaust components. This creates a risk of rapid coolant loss, overheating, loss of power while driving, and potential engine compartment fire. The Ford service advisor told me directly that he has “seen this many times,” which indicates this is a recurring failure on ecoboost engines and not normal wear. This suggests the coolant line design or fittings may be defective and failing prematurely. The repair estimate was extremely high because the dealer included replacement of both exhaust manifolds. This failure occurred without warning. If the coolant loss had happened at highway speed, it could have caused sudden engine overheating or power loss. I am requesting NHTSA investigate turbo coolant line failures on Ford ecoboost engines due to the safety risk of coolant leaking onto hot turbo and exhaust components.

My vehicle is currently subject to an open Ford transmission safety recall for which no repair remedy is available at this time. The vehicle is experiencing a recurring and dangerous failure while driving. Approximately twice per day, during my normal commute, all vehicle electronics suddenly shut off while the vehicle is in motion. At the same time, the wheels appear to lock up, causing a sudden loss of vehicle control and creating a significant crash risk. When the failure occurs, I am forced to immediately shift the transmission into neutral while the vehicle is still moving. After approximately 5 to 10 seconds, I can shift back into drive and continue operating the vehicle. However, vehicle electronics often remain inoperative for the remainder of the trip. This condition is occurring repeatedly and has become more frequent. The issue currently occurs approximately once during my drive to work and once during my drive home. My commute is approximately 20 minutes each way. The vehicle has not yet been involved in a crash, but I believe a crash is likely if this condition continues. The sudden loss of power, loss of electronics, and wheel lockup while driving creates an immediate safety hazard to myself, my passengers, and other motorists. I am submitting this complaint because the vehicle is subject to an active safety recall, the condition appears related to the recall, and no repair remedy is currently available. I believe the vehicle is unsafe to operate.

The contact owns a 2015 Ford F-150. The contact stated that while driving at various speeds, the vehicle suddenly decelerated, the tires were dragging, and the engine temperature was high. The check engine warning light illuminated. The contact's father performed a diagnostic scan on the vehicle and retrieved a diagnostic trouble code indicating a pcm and engine cooling system failure. The vehicle was taken to the dealer, where the coolant hose was replaced, and coolant was added to the vehicle; however, the failure recurred while leaving the dealer 5 minutes later, and the vehicle failed to exceed 10 mph. The vehicle was driven back to the dealer, and it was determined that the coolant temperature sensor had failed and needed to be replaced. The vehicle was not repaired. The contact stated that the failure might be related to NHTSA campaign number: 26v237000 (power train); however, the part to do the recall repair was not yet available. The manufacturer was not contacted. The failure mileage was unknown.

The contact owns a 2013 Ford F-150. The contact stated that while driving 70 mph, the vehicle went into limp mode and the vehicle unintendedly decelerated. The orange wrench symbol was displayed. The contact pulled over for five minutes, and the computer was reset. After the vehicle was restarted, the vehicle operated normally. The local dealer was contacted and confirmed that the vehicle was not under recall or warranty. The vehicle was not diagnosed or repaired; however, the contact was provided an estimate for the repair. The vehicle was taken to an independent mechanic, and the failure was associated with the wheel speed sensor. The manufacturer was not notified of the failure. The failure mileage was approximately 141,000.

While driving about 60 mph on the highway, all warning lights on the dash suddenly came on and the truck immediately lost power/shut down. The wheels sputtered or somethting like that, not sure how to describe it. I was able to safely get off the road and restart the truck. After restarting, it drove normally again with no obvious issues. I recently received a recall notice describing very similar symptoms related to the transmission/lead frame issue, but the notice stated no remedy was yet available. This created a serious safety concern because the failure happened unexpectedly at highway speed. Here is the recall info: issue date 2026-04-14 campaign 26s28/26v237.

The recall is 10 months old and no remedy offered. Every time I get behind tge wheel I'm risking an injury or death of myself or someone else. I can't sell my vehicle because it would put the next owner at risk. Do I have to wait until there's an injury or death to have something done about this?.

Vehicle is experiencing severe, dangerous transmission malfunctions matching Ford safety recall 26s28 / NHTSA 26v237. Multiple times while cruising at highway speeds, the vehicle has abruptly downshifted into 2nd or 3rd gear without warning, causing violent engine revving, sudden loss of forward momentum, and severe steering wheel shaking. These incidents occurred in rainy, low-visibility environments. The vehicle is primarily driven by my wife with our [xxx] granddaughter inside. A sudden drop to 2nd gear at highway speeds in low-traction conditions creates an immediate, catastrophic risk of a high-speed rear-end collision or loss of control. On wed [xxx], we took the truck to hubler Ford (shelbyville, in). The service department officially diagnosed the vehicle and acknowledged the malfunctions are caused by recall 26s28. However, they refused to repair it because they are "waiting on a software code" from Ford corporate, estimating a delay until mid-July 2026. They refused to provide a safe loaner, forcing us to drive an actively malfunctioning vehicle. On 6/18/26, I called Ford national customer service to escalate this safety issue and request an interim rental. The Ford rep contacted hubler Ford but failed to authorize a rental. Instead, Ford corporate placed me back in a customer service loop, telling me to discuss symptoms with the dealer again, even though the dealer already officially diagnosed the defect. This loop has caused numerous 20+ min holds with no one addressing the issue. Both Ford and hubler Ford are refusing to provide intermediate safe transportation for an officially diagnosed, severely malfunctioning safety-recall vehicle, leaving a toddler exposed to a severe highway crash hazard. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving and slowing down for a stop sign and the engine shut off by itself while still moving at appx 10-15mph. The display had several warning lights appear, and the message "auto start stop, shift to p, then restart engine". I have the auto start stop disabled on my vehicle, so there was no reason for my engine to shut off while decelerating. I searched online for potential causes and discovered that there are numerous incidents of this happening (engine shutting off while moving) to drivers that have deactivated the auto start stop on their vehicles. See link: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

In the second year of ownership I noticed that occasionally I would get no throttle response from the gas pedal when trying to accelerate. After several occurrences I began to pay close attention as to when this was occurring. I found that this occurs mostly, not exclusively, when I am slowing the vehicle to a near stop, not a full stop and then accelerating to continue, like slowing to round a corner on a green light and getting into traffic. For example, I was exiting a home depot parking lot, the driveway exits to the roadway. As I approached the driveway to enter the roadway I slowed, preparing to stop. Seeing no traffic on the roadway I then pushed the accelerator to enter the roadway. The pedal was dead, I got absolutely no acceleration. I pushed the pedal down slowly, nothing. I pushed the pedal to the floor, nothing. The truck rolled out onto the road, I coasted to the side of the road. Had there been traffic I'd have been hit. This has happened 20 times in two years and 80k miles. The most recent event was this week with my wife present, very scary, dead pedal, not throttle response. If you research "dead pedal" on google, you will get the following response: the "dead pedal" in the Ford F-150 powerboost—a dangerous lag or total loss of throttle response—is a widely reported issue, particularly when accelerating from low speeds, turning, or right after starting. [1, 2, 3] the cause can range from a software glitch to transmission issues or failing sensors. Ford said there was a TSB, however the work performed had no effect on the dead pedal on my truck. Invoice attached from March 2026, it just occurred again this week. I am going to trade the vehicle in but I doubt that Ford will disclose this flaw to the next buyer, it will be their's to discover, hopefully not by "accident". I am going to trade this vehicle in and I'm sure the new buyer will have no idea of this potentially deadly flaw.

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?.

Our truck was smoking from the exhaust and we took it to the local Ford service department. They determined the oil pan is leaking, there is a coolant leak from the engine, requiring a new engine, and also the need for turbos. These are the exact issues that are included in this service bulletin making dealerships aware. If this is such a widespread problem with these trucks, why is there not a recall to make proper repairs?.

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.
