2021 FORD F-150 Electrical System Problems

The vehicle reported a charging system failure alert and came to a jerking stop. The battery was completely drained and the alternator had failed at 71,000 miles. The vehicle stopped in the drive lane on a heavily trafficked road. The emergency release lever was found and pulled to allow the truck to pull over.

I was in the parking lot of my local grocery store, and the truck all of a sudden gave me an indicator that there is a "park brake fault-service now." I was stranded and had to have someone pick me up for this, This is after hours so I cannot call the Ford dealership until the following day. I now see Ford issued a recall for this under 23S35. However, when I look up my VIN under Ford, that did not show, and thus, we did not address this earlier when that should have happened. That is a problem and needs to be addressed with Ford ASAP. What if I was driving and this happened??!!

Started after McGee ford did a service on my truck Apparently they told ford they repaired electrical recalls which I wasn’t having issues with nor did I know They did anything! They did however erase the recalls so that was 8-2024 shortly after my truck experienced major electrical issues, another dealership told me it was gonna be 6k and 4 weeks to fix I was in awe I left with my truck that had no blinkers no air bags and so on 15 safety codes! I battled this for a year and then my parking break locked up while driving 70 on the highway! That’s the recall megee claimed they fixed I’m not rich single dad 100% of rhe time and I sure my kids everywhere daily, I do research call ford find intact i had a recalll so im thinking it will get fixed! 6 weeks later they not...

When temperatures are below freezing, the passenger side door remains locked, and cannot be unlocked with the key fob or the unlock buttons on either the driver side or passenger side door. The manual door lock cannot be pulled out, as it sinks down inside the door, and there is no external locking/unlocking mechanism to use the key to manually unlock the passenger side door. Dealer said there was nothing wrong with it, but brought it into the shop to look at it, where the temperature is higher than freezing.

Daytime Driving Lights Are disabled due to an electrical defect.

The hybrid battery in a 2021 Ford F-150 Powerboost failed due to apparent shorting. (P/N ML3Z-10B690-D) Pictures were taken by service department at the Ford dealership, and can be provided upon request. There is concern that the system could catch fire and spread under the vehicle. There have been other similarly identified failures reported in online communities, but cannot verify the information. Failed component is currently with dealership service department, therefore, cannot verify if there has been further inspection of part. Prior to failure, there were no indicators of problems or faults. As the failed part is not easily accessible and there is no routine maintenance, there is no way to validate when the part failed.

My truck thinks my parking brake is engaged so it constantly flashes the “brake” light, constantly chimes while driving and says parking break malfunction, talk to dealer. I brought it to Webber family Ford in Detroit lakes MN 56501 and they checked it over including the safety recall location for recall 23S35. They said it was not the recall location and I would have to bring it in Monday for another appointment. When I got it home that day I crawled under to check that location. I see visible green which usually means corrosion and the protection around the harness seems warm. I also noticed the "recall" was not completed how it is shown on fords recall paperwork using the zip tie as a wear location so it isn't the harness itself. That is not how mine is. I have photos to prove that. I spoke with corporate ford today...

Transmission downshift to first gear on the highway

I purchased my vehicle in October 10th of 2025. I drove the vehicle home 2hrs away on the Friday. On Sunday the 12th I started the vehicle with a error of " Park brake fault Service now" I had the car taken to the nearest Ford dealership as it sat for 3 weeks. I was told the recall for the vehicle around this issue has been done twice so Pundmamm Ford the local dealer did not want to do it again. They ended up replacing the driver rear brake caliper bled the brakes and said this fixed it. They did not replace the harness as they said twice repaired was weird that Ford allowed this. I ended up paying for the repairs caused by this recall of over 1000.00 dollars. I have drove it now for two days and already the brake light engaged. Luckily it released and I was...

At a stop light vehicle will turn off and nothing electrical will work. It will have to be restarted, While turning at low speeds the electronic steering completely stops working and almost hit another car. All electrical power failure until modules reset then will start. This all happens randomly so it could happen at any point and cause serious injury. Ford can't seem to find a repair for the intermittent issue.

Vehicle: 2021 Ford F-150 Component: Exterior Lighting – Daytime Running Lights (DRLs) / Headlights (High Beams) Safety Concern: Vehicle visibility and forward illumination Both daytime running lights (DRLs) on my 2021 Ford F-150 have failed completely. After the DRLs stopped working, the high beams also became inoperative, leaving only the low beams working. The Ford dealer attempted a repair by replacing the control modules, but that did not fix the issue. They advised that the entire headlight assemblies need to be replaced. However, these assemblies are very expensive, so I have not replaced them yet. I am currently limited to using only the low beams. Without DRLs, the truck is less visible during daytime driving, increasing the risk of a collision. Without high beams, nighttime visibility is reduced, especially on rural or dark roads. This failure affects federally required lighting functions, compromising safety in both day and night driving. The...

Gear shift selector gets stuck in park, drive & reverse. Unable to move vehicle & blocking traffic for a period of time.

Unable to update automatically, vehicle was constantly attempting to connect, draining the battery (I replaced the battery and carry jumper cables and a quick starter now). Took into dealer and they are unable to perform updates. They have had the vehicle for 2 weeks and no progress. The forums online have indicated the vehicle was built with whatever parts they could get due to the COVID supply chain disruptions to normal parts. The software and subsequent updates do not remedy matters. I have no documents to upload, still in shop.

Vehicle lost all power and stalled while driving. Vehicle also stalled at idle when waiting at an intersection, and another time while waiting at a stop sign. No longer starts. Appears to not be receiving fuel and is returning code P0627 "Fuel Pump A Control Circuit / Open" and will crank but not start. Required towing back to my residence. FordPass sent a "Service Engine Soon Warning" stating "the powertrain control system has detected an electrical fault with the fuel pump and its associated wiring". The symptoms match those in 25V455 but this VIN number is not listed in the affected group.

Pro power onboard doesn’t work.

The alternator failed at 60,000 ish miles. Specific mileage can be provided upon request. It appears this is a common problem as alternators and alternator parts are unavailable. I have had to order a custom alternator.

I had driven the car about 15 residential miles to Home Depot and back. As I was driving into my driveway I smelled smoke and looked forward to see a puff of smoke coming out from the front, driver's side wheel well. I put the car in park and pulled the hook release control under the steering wheel. Suddenly flames were coming out the sides of the hood, about 12" high. I pulled the car quickly away from the house and trees. Put the car in park, as the flames were now engulfing the entire hood. I quickly got away from the car and called 911. The Fire Department is close to my house, yet by the time they arrived the car, including interior cabin, was fully engulfed in flames.

Fords Sync system fails to connect to internet and won’t update resulting in transmission failing to relearn as you drive

Drove it out to CA from Texas. Purchased for Planet Ford who told me the truck was k to drive and no axel problem. Drove it out to CA from Texas when we moved in late April - after that went to Santa Barbara and dashboard controls went dead. Speedometer and may other controls stopped working. Truck felt sluggish. Took it into Tuttle Click Ford Lincoln in Irvine and they said they real axel was about to fall off and took the truck away. They've had it for a month and said they may have it for another 2-4 week or longer.

What component or system failed or malfunctioned, and is it available for inspection upon request? -The electrical system malfunctioned causing a complete system failure and shutdown of the vehicle. The vehicle came to a sudden stop in an intersection and could not be moved. How was your safety or the safety of others put at risk? -The vehicle instantly died going through an intersection causing the steering column to lock up, the parking brake to engage and transmission to remain in drive while the vehicle was stopped without any power. This was a sudden and abrupt stop where all control over the vehicle was lost, and I came to an immediate stop in the middle of an intersection. The vehicle would not restart. I could not disengage the parking brake to move the vehicle out of the intersection due to the complete loss of power. The transmission would not shift...

Black screen on main vehicle screen. Ford has a Customer Satisfaction Program (12M02) that extended the warranty coverage for the Accessory Protocol Interface Module (APIM), a key component of the SYNC system in certain Ford vehicles. This program covers the APIM for 5 years from the warranty start date, regardless of mileage, which is a longer coverage than the vehicle's original warranty provisions for this part. The coverage automatically transfers to subsequent owners. However, Ford is saying that I do not qualify and cannot define the qualification criteria. If some affected vehicles are eligible for repair under this CSP, then all affected vehicles should be.

Related to TECHNICAL SERVICE BULLETIN Various Gear Shift Module Concerns 25-2045 I experienced an issue where my truck was stuck in drive and the engine off. The truck could not be turned on if it wasn't in park, but couldn't be shifted unless it was on. This appears to be a very common issue as I made a post on Reddit [XXX] ) and many other users noted the same issue (low milage, relatively new tucks) with the same fix - a tow to a ford dealer and a $1000+ replacement of the shift module. The service manager told me it was "a common issue". It should be categorically impossible for a $70k+ tuck with less than 40K miles to be unable to shift gears due to faulty computer components. Ford didn't consider this issue under warrantee. Ford should have this module recalled - it is unfair for consumers to...

In December 2024, I brought my vehicle to my local Ford service center to address an infotainment/display screen issue. My display screen went completely black giving me no access to basic vehicle functions like radio controls, climate, and most importantly, cameras. Since this time, my vehicle has been back for service on 4 separate occasions without any success. The longest service visit being 2-months while "Ford Engineering investigated the issue". During this time, they ran diagnostics, replaced the infotainment screen, and finally the APIM unit but to no avail. Ford assured me that this was an isolated issue and the first of it's kind. I am scheduled to go back to my service center on June 3rd to have "tokens" installed on my vehicle. This will allow Ford's Engineering team to recreate the issue on their end. Today I read that Ford opened a recall for 1.1m vehicles for display/camera...

Part DG9Z13A018E (Ambient Light Sensor) fails to properly read Daylight during warm months. Inverted value (reading of VERY DARK) persists for at least 10 minutes. Appears to be temperature dependent; meaning, the temperature of the sensor/dash/housing is very hot and skewing the reading. Instrument panel dim. 12" screen dim. Reverse image (parking assist) dim as 12" screen is dim. When occurs, can be disabled by turning auto-headlights to OFF position. When cycled back to AUTOMATIC, condition reasserts and dims both the cluster and screen. Issue has been verified at dealership since 2023. Cannot replicate issue when stored indoors, raining, overcast, cold, etc. Requires full sun and warm day. Vehicle cannot be spared for additional diagnostics without rental/loaner provision. Will ask to attempt to replicate during upcoming recall maintenance and other TSB/SSM diagnostics to correct lingering OTA update/software issues that cause low state of charge conditions.

My rearview backup camera blacks out won't load, cuts off and on. When in drive it still takes a while for it to still load the radio and navigation. It blacks out and won't load when I start the truck. By the time I back up, still not loading, and start to drive it takes a few minutes maybe 10 for it to finally start working and displaying the navigation and the radio. I've had this issue for a while. And if other makes and models are having the same issues, it has to also be affecting my make and model being it's the same issue.

The day time running light on the driver side is out and is a known problem for the 2021+ F-150’s with LED headlights that I have seen.

Drivers side head light is half working

DRL lights are dead after three years of ownership. Dealer wants $1600 per light assembly to repair them. Cannot afford to repair them. makes the truck less visible day and night.

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!

While driving there were no warning indicator lights illuminated on the dash. He stated there were no mechanical defects, noises, or smells to be noted. Near Milepost [XXX] on [XXX] both occupants saw smoke begin to come from under the hood. The employee pulled the vehicle to the side of the road. Both employees exited the vehicle to open the hood. Employee stated he reached down to pull the hood release and when he looked up flames were visible above the hood. Employees moved away from the vehicle and called 911.

The DRL on the 2021 F150 Quad Beam headlights burn out continuously. Ford needs to step up and fix this issue. This issue is a safety matter.

Passenger Daytime Running Light went out on me. Happened to other 2021-2024 Ford F150’s too. Hazardous to others due to confusion of lighting. No warnings at all.

While driving the parking break activated. I was in the middle of the road with my newborn. I believe my truck should have been recalled since this is something that other F150 had. I took it to the Ford dealership and they said there was no active recall on this vehicle. So I had them check it since it’s such a high safety concern.

The Instrument Panel Cluster will reboot when driving leaving the panel blank with no speedometer or other vital information. The system will reboot after a short time, sometimes multiple times and has occurred when driving at speeds of 30, 35, 50, 65 mph. This reboot leaves the driver without vital information, causes confusion and is a distraction putting the safety of all occupants at risk. This has happened a multiple times and may be is similar to SSM 50294 where emojis causes the Instrument Panel Cluster to go blank or reboot during incoming or outgoing phone calls where there are emojis alongside the text of a name of contact. Unfortunately, I did not learn of this error until I had dropped the vehicle at the dealer and researched myself. I have a heart emoji next to my wife's name and would gladly remove this, but the dealer indicates a full...
