What 937 owners told NHTSA about the 2021 Ford F-150 Supercab Diesel

My truck completely shut down while leaving the shop and I was only going about 6-10mph. The dash alert stated "fuel accessory" or something in orange, sorry, I panicked a little:) I took it to Bradley Ford the next day and they couldn't fix it as they didn't know the issue. This happened a second time, but didn't shut off completely, it just felt like I was running out gas (full tank). I do live in Lake Havasu City, Az and it's hot here so I don't let my truck go below 1/2 tank hoping this will help avoid a major accident. Thank you!

My f150 has 47k miles and it’s been serviced every time it was supposed to and the engine failed. Oil leaking into the engine destroyed it. I looked up 2021 F150 v8 coyote engine and it’s a known issue

I was turning left from a side street onto a divided highway and stopped in the middle to wait for an opening in traffic. When one came I hit the gas and nothing happened. Pressed it again, to the floor and nothing happened. I then put the truck into reverse to back out of the way of traffic because the truck rolled forward a bit when I attempted to accelerate. I then waited for a very large opening and attempted to accelerate again. Pushed the pedal and again nothing. I then pressed it to the floor and held it there. The truck very slowly began to accelerate and then after about 20 seconds accelerated like normal. The truck seemed normal the rest of the way home.

My engine failed. They recalled this engine but mine wasn't recalled. My engine did the same thing as the recalled engine did. Excessive oil consumption. When I first took it to Ford dealership it was under 60K. I have had problems with my truck since Easter have taken it to them a few times. The problem was never fixed and now Ford will only cover 4,950. The engine is 12k. I feel since the engine in my truck was a recall on alot of engines. Mine should be covered under recall or warranty up to 60,000 miles. I have nothing but problems since I bought the truck. I started taking the truck to have it looked at since March to other places they couldn't help me so they told me to take it to the dealership. They keep fixing something on the truck but never the part that was broken. They told me it would be ok to drive it and so now I am over the mileage for my warranty. I don't think I should have to pay to replace my engine when it only has 61K miles on it. so they told me to drive it and then it started knocking and the engine failed. The service manger told me it was a failed bearing. certanily no lack of maintenance so why am I stuck paying for this when it wasn't my fault. they found some damge on one of the rod bearings on the bottom. 2021 Ford F-150 V8 that engine had a recall on it. Not sure why mine wasn't recalled. Can you please help me. My truck is at Larry H Miller Ford in Draper Utah. It has been there for 5 weeks this time. Still no engine in it.

Vehicle is consuming excessive amounts of motor oil, requiring the addition of 1-2 quarts every 1,200-1,500 miles. Check engine light has illuminated once when engine was five quarts low, this was when I realized the problem. Ford has attempted to correct with TECHNICAL SERVICE BULLETIN 19-2365, (5.0L - Excessive Oil Consumption) which I had performed on my vehicle and it did nothing to correct the issue. My greatest concerns are with premature parts failure and unexpected engine failure. I have written letters to Ford regarding this issue and have not received any response to date. I do have records of additional oil added since first realizing the issue existed.

My truck falls in the recall for the valve failures and they finally have parts to do the test but there is tons of documents and articles saying Ford agreed with NHTSA to provide a 10 year 150k warranty to people who fall in this recall. per you guys investigation EA23007 under 24N12. When I talked to Ford and the dealer they say that's not a number. Just on principle this is crazy. I bought my truck thinking well atleast Ford is taking care of people on this. After reading the states summary saying Ford would provide that.

While stopped at a traffic light or in an intersection preparing to make a turn, the vehicle’s engine will randomly shut off. Simultaneously, a pre-collision warning appears on the display. This causes the vehicle to become temporarily disabled, even as oncoming traffic approaches. To recover, the driver must shift the vehicle into park, restart the engine, and quickly accelerate out of the way to avoid a potential collision.

Received safety recall October 2024 stating vehicle may crash - have not received any further notice about repairs

NHTSA ODI 11663195

The engine can fail at any time. The truck has not been fixed in a timely manor. I pull trailer with livestock. I need to declare the lemon law on this vehicle to get one that is reliable.

NHTSA ODI 11661102

This safety recall was issued in August of 2024 on an engine valve, this is the only vehicle I have. The engine valve has the potential to crack increasing my risk of crashing, I have a 3 year old. I called Tomball Ford last year in November and was informed they would have the parts by January 2025. It is now May 2025 and no parts or correspondence for the dangerous matter. In fact another recall has been issued

NHTSA ODI 11661129

Harsh shifting, abrupt or hard shifts. Hesitation and delays when accelerating feels unsafe, especially at highway speeds. This is an ongoing issue and has been going on for quite some time. Cannot pinpoint a specific date.

Trucks been in to Ford for repairs 38 times for force motor shuts down while driving. Ford wasn’t able to duplicate so they kept blowing me off. Finally morries of Okemos actually drove truck 45 minutes like I requested because it only shuts down after truck warms up. They have got it to finally shut down and have realized the panic of not being able to start back up until it’s in park and how dangerous it is to be driving 70 on highway and if you break it does force motor shut down. Ford refuses buy back and vehicles not safe to drive. They still have no answers. At this point I’ve went 245 days without a vehicle while being in and out of shop. Mine isn’t the only one out there. There telling people if they can’t duplicate when they drive it they can’t fix it. Problem is these dealerships aren’t driving consecutive enough to fix it. Thankfully mirrors did thinking I was crazy and dealership says they have never seen this actually happen. Just from talking I know several people with same issue.

Failure to remedy engine valve recall. Was informed that a remedy would be ready by Q1 of 2025. That deadline has passed and nobody at Ford has any information.

NHTSA ODI 11657110

Multiple times now while driving at low speed and usually making a right hand turn, the throttle becomes totally unresponsible to driver input. Pressing the throttle does not increase ICE rpm and does not accelerate the vehicle. This has occured while entering active roadways and has created a dangerous situation multiple times. Someone will be injured with these vehicles, it is only a matter of time if this failure to accelerate issue is not recalled and fixed. The date below is only the last incident. I now have over 120K miles and it has done this well over 50 times.

While traveling on a local highway in the far left lane, the engine completely died (no engine light came on). I was trying to negotiate traffic while getting to the shoulder of the road, and the transmission began shifting itself into park. I grabbed the shift lever trying to prevent it from going into park; however, it did just as I reached the shoulder of the road. At this point, I had slowed to ~25 MPH, but it still locked the tires up and slid a few feet. After turning the key off, removing it from the truck, and opening the door, I was finally able to restart it and I went straight to my local mechanic. He attached a code reader; however, there were no codes displayed. He stated they probably cleared out when I restarted the truck. This happened a couple of months ago, but my wife has been fussing at me to report it.

Whining or whistling noise at idle. Bangs when shifts to lowest gear.

My truck has a 2.7 eco boost engine than has failed around 134,000 miles. The truck had a couple of misfires over the last couple of months, but otherwise no issues. I drove the truck one Saturday, did not drive Sunday, and on Monday I am told the engine is completely seized and I am responsible for replacing the engine. Ford will not attempt to determine if the recall for the valve intake stem has caused the issue and now I am spending over $12,000 to replace a 4 year old engine with no other issues.

NHTSA ODI 11646428

I was stopped at red light intersection my truck went into idle mode (start/stop) when light changed I tried to proceed through the truck engine/electrical transmission locked up. I had to turn the truck completely off and open one of the doors to be able to restart the truck and move through the intersection. it has done this repeatedly I have taken it to Ford they have tried to charge me an astronomical amount to diagnose it.. with no guarantee of it being fixed. I have almost been rear ended 3 times!

NHTSA ODI 11629600

Recall with no remedy.

NHTSA ODI 11629413

At 30k I noticed the transmission start shifting hard especially when down shifting. I called the dealer and expressed by concerns when doing my normal oil changes. The dealer said it was normal. Now at 42k the truck skips 2nd gear and when shifting between 3rd and 4th it hits hard. Also an independent mechanic shop said the engine is making a weird winding sound. Sounds like the barring in the turbos are going. Again I tell the dealer and they said it's normal for the 3.5 ecoboost to sound like that. Currently it's at the dealer getting the transmission worked on. I know I will be having engine issues, that sound is not normal. I want it on record that it started happening around 30k.
