After towing a trailer for some miles (130 or so in this case) the vehicle stalls/dies after pulling up to a traffic light or stop sign. This repeated itself multiple times (7 in one town) and twice in another town before getting home. This happened with the auto stop feature enabled and disabled. System chimed at each occurence and indicated that driver should put truck in park and turn ignition key.

After a period of towing a 5200# trailer the 2.7L ecoboost engine would stall when not throttling. Meaning, anytime slowing down or stopping the engine would cut off unexpectedly, forcing a manual restart. The truck did restart if the throttle was held in pushing gas and then throwing the truck into drive gear to move, however the throttle would have to continue to be pushing in order to maintain power. This occurred at 30+ mph in slowing down for accident/construction traffic as well as every time stopping for lights or gas. Issue occurred many times during trip, but only while towing. After disconnecting trailer and allowing vehicle to cool/rest for an hour issue did not return until after running with trailer being towed at highway speeds again.

5.0 has a distinct rattling noise at lower RPM's. the engine also has a loud knocking noise which is different from the rattling noise. I have experienced the gas pedal temporarily sticking and the engine has a miss. Also way down on fuel economy at 11mpg's. this vehicle is 3 months old and dealership says and (Ford corporate supports dealership) that I have to pay out of pocket for any engine diagnostics regarding my 5.0 engine problems

Truck shuts off when pulling a camper and will not run after restart unless you rev the engine and quickly pull the shifter into drive and accelerate quickly. The instrument panel shows 'auto startstop shift to P, them restart engine.' This has caused many near miss accidents. The vehicle will stall when you try to cross an intersection or pull away from a stop sign.

On Jan 25th, 27th and 29th a "malfunction indicator lamp - regulatory' light went on, and at the same time there was a warning of 'reduce power' the truck power results in an reduction of speed to 10-20 mph. This happens at speed, 60-70mph on the freeway, to 10-20 mph. Fortunately I was able to get off the road. I took the truck to the dealer, after a 'software' upgrade I was told the truck was ok. However on fed 11th at night on a highway with no shoulder the "malfunction indicator lamp - regulatory' light when on, and at the same time there was a warning of 'reduce power' the truck power results in an reduction of speed to 10-20 mph. The only way to get the truck going, is to shut it off and re-start the truck, the engine 'light' stays on, however the truck runs fine. Its now at the dealer, for the last 3 days. They think it has something to do with the turbo over boost. My main concerns is not the turbo, but the 'coding' that de-rates the engine, when at speed resulting in an immediate safety issue. While on all of my occasions I was able to get the truck restarted without another vehicle running into me. I am requesting assurances that the 'code' or programming that causes the reduced power to be removed. For me this is far more important that making a repair to the turbo, as it's directly to safety.

While coming to a stop, the engine shut off and a message displayed that the engine auto start/stop function was engaged, put the vehicle in park, and re-start engine. This was with the auto start/stop feature already disengaged, which I always do. It is very dangerous for your engine to cut off while driving and have to stop, put it in park, and re-start it in moving traffic. I have read multiple reports of this same problem on several forums. Vehicle is a 2018 Ford F150 XLT, 5.0 engine, had about 4000 miles on it.

Engine revs up on it own: When driving at a speed ~ 10 mph down my graveled 600 feet driveway, the engine revs up, exceeding 6000 RPM. This has occurred on 5 occasions, twice in November and three times in December, latest being 12/24/2018. I had the vehicle less than 5 months with 3300 miles on it. I noted when it occurs, it's when the vehicle is first started up. The rear tires dig in and start spinning, throwing gravel. Pressing the brake and coming to a complete stop lower the RPM and settle the engine down. This could be a accident waiting to happen in highway or busy city traffic. I've noted on carcomplaints.com, several Ford F150 owners have this problem.

My truck has the 2.7 engine. While towing our trailer longer distances the truck will stall while exiting the highway or stopping for fuel. It will not restart without pressing on the gas and dropping it into drive. Its very unsafe because you might be in a intersection and cannot steer it because of the electric steering. This has been a ongoing issue sincee it was new and they cannot figure out the problem. Its to the point that I dont feel safe towing with this truck especially with my family in it.

Vehicle stalls whenever coming to a stop after towing for more than an hour. Requires the vehicle to be placed in park to restart, but will continue to stall out immediately. Dangerous at intersections and stop-and-go traffic. Also stalls (when towing) when attempting to restart after refuelling. Only way to get the vehicle to start without stalling it to keep the gas pedal pressed to keep the RPM above 1500; or wait 10-15 mins for engine to cool. No check engine/computer system error given at all. Only stalls when vehicle has been towing over a long distance. Occurred 20+ times a day over the course of traveling across the us and Canada in July/August 2018. Took the vehicle into Ford service center in longmont, co, but were unable to diagnose with no code. I am seeing more and more reports of the same problem occurring with 2018 Ford F-150 2.7L ecoboost models. Https://www.Ford-trucks.com/forums/1515205-2-7-ecoboost-stalls-dies-after-towing.html I have a video of the stalling occurring after refuelling but file size is too large to attach. Let me know if you would like it emailed directly.

Engine makes a very loud clicking and ratcheting sound after every throttle lift for the first 15min of engine operation. I did not hear it until the Ford dealership worked on the intake system for the stumbling and hesitation issues. It can be hear over 300 feet away. My neighbors and friends all ask what is wrong with my new truck. I suspect the engine vibration issue is related to this very loud intake noise.

My 2018 Ford F150 XLT V8 with 10-speed transmission has failed to accelerate from a stop after idling. The start/stop function is always disabled when I drive. The truck hesitates and stumbles upon light acceleration. One time it continued for a few seconds before quitting completely. It makes me really nervous when I am pulling out into traffic as I feel it may hesitate. I give plenty room to traffic and expect it to stumble so that I do not get into the middle of the road and have it quit. I've never had a vehicle that I had to substantially change my driving behavior to adapt to its many faults. Dangerous truck.

My truck has a constant rattle/detonation/preignition noise during all driving. It is especially bad during hot summer months. It has only gotten worse as months have gone by. It is especially noticeable while climbing very slight uphill grades and at speeds between 35-55mph. It can be heard from inside and outside vehicle. The noise is coming from engine. A vibration and shudder can be felt in vehicle when noise is present. When it is really bad, the sound is very loud and sounds like a metal hammer banging on inside of engine. I was told this would get better with mileage, but has only gotten worse. I have audio and video recordings of noise over then past 10months. I am very worried that this engine is going to fail.
