general problems of the 2021 Ford F-150 - part 1

Rear glass window completely shattered for no apparent reason while sitting in parking lot parking car. Recent snow and outdoor temps about 26 degrees. Had driven the car a quarter mile with rear defroster on.

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.

Rearview camera stop displaying image for 24 hours.

The rear windshield spontaneously exploded while the vehicle was stationary. I confirmed this was not caused by any impact or debris. There have been several other reports on various websites of this issue, across multiple models including the f150 and bronco, and potentially being caused by faulty wiring of the rear defroster. Ford has not issued a recall and will not accept responsibility for this defect.

Guessing the date below truck shuts off when trying to take off and go. This has happened a few times and even pulling onto a main highway. This is a very dangerous situation, and I have contacted Ford and they have stated there is no fix for this. I have contacted carvana which is where I recently purchased the truck within the past month and they state the recall was listed and there's nothing they can do it's up to Ford to fix a recall. They will not take the truck back and now we are stuck paying for over $30,000 on this truck and it keeps stalling on us. We cannot afford for it to just sit in our yard and pay for it if it's not running. We need help to get this fixed. We have no idea what's causing it but assuming it could have everything to do with the open recall or the battery. That battery is over $4000 if we have to replace it. Another thing we noticed is the led lights on the headlights went out randomly and haven't come back on. Another very expensive fix for a truck we just purchased less than a month ago. We took the truck in the shop within the first few days of owning it due to a few issues we felt were not right like pulling to one side, feeling as if it were going over rutted areas on the roadways with a bump and jerk to it as well like it was a transmission issue. The insurance company with carvana choose the place to take it to and we dropped it off and the next day they called and stated nothing was found to be wrong with it and carvana knew we were out of return in time to replace it when they had us drop it off it was like another day.

Ford has issued a TSB 22-2372 regarding the rear camera image going blank when placing the vehicle in reverse. This issue clears by restarting the vehicle. The cause is a software error in the image processing module and sync 4 system. The danger is backing up without being able to see anything besides what is in your mirrors without the software update to fix the issue. Numerous children have already died because of vehicles without the safety of a back-up camera. I took my vehicle to the dealership to have it fixed and was quoted almost $1000 dollars to update the software. I complained and the dealership forwarded my complaint to Ford who gave "assistance" bringing the bill to $361 dollars. My question is why a mandatory recall hasn't been ordered for this obvious safety issue? luckily, I can easily pay this but what about those who cannot? I asked Ford (case #cxh-xxx) why they are not providing the fix for free since it is a safety issue and they used the excuse of the warranty being expired. Hopefully NHTSA will make Ford fix this safety issue for fellow consumers. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

A certified independent inspection company discovered welding on the main chassis of my Ford F-150. The welding is located on the front left frame area. I purchased the vehicle brand new, and it has never been in any accident or collision. This welding on a critical structural part creates a serious safety risk. Frame integrity may be compromised in normal driving or in the event of an impact. I transport my children daily in this vehicle, and I am afraid to drive it due to the possibility of structural failure. The official Ford dealer inspected the vehicle and kept it for approximately three weeks but provided no explanation or repair. The regional Ford office has delayed their technical report for more than five months with no response. The defect has been confirmed and is permanent. No warnings or lights appeared prior to discovering the issue. This is a manufacturing-related structural defect affecting vehicle safety, stability, and integrity. A proper safety resolution is required.

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 able to drive home. I have called Ford on this multiple times as well talked with supervisors and need escalation at this point.

My rear axle bolt broke in early October. It has now been over 3 months and I have zero update on when my recall will be addressed. I have a rental, but this is beyond the fair and reasonable time frame to repair a recall. The service center can provide zero update or status of when this will be resolve. I'm making 4 payment on a vehicle that I don't have. What other recourses do we have. Can manufacturers just take months on end to repair when customer are without their personal or work vehicles?.

My truck will not update its internal software that controls everything from windows to abs braking system. My truck has numerous pending updates, verified by my dealer and fmco update section, that are not being sent to my truck. The updates are there for a reason, to improve and to prevent issues. I asked my dealer to do them, they said it would cost $1500 to do it since they would not install over the air as they should. I contacted Ford on 9/12/25 and they refused to assist by either paying the dealer and or by using my Ford esp warranty. My safety is at risk because these updates address transmission issues, braking issues, electical issues etc all that could fail and cause an accident. Add these failure to update with the exisisting fuel pump problem and the truck is a serious problem . I am told by Ford that my updates are "stuck" and that there is nothing that they can assist with and I must take to a dealer and pay for the updates that others get for free. But, should there ever be a "recall" for my trucks failure to update, I can apply for a refund. I have about 12 different updates that will not download to my truck. In the history of the truck, this is not the first time it would not download updates. Shortly after it was built it was taken to Ford and a "forced update for the bluecruise technology" had to be done. Critical software updates to the trucks main computer that do not initiate is not acceptable and a danger to this truck! thank you!.

Catalytic converter has failed and needs replaced.

On Sunday, [xxx], I was driving on a state highway in my 21 Ford f150 fx4 with my family. 67mph, 73 degrees sunny outside. The front portion of my moonroof/sunroof exploded, shooting glass shards internally all over my truck/passengers and externally into the bed of my truck, and into the boat I was towing. Multiple people had glass shards embedded in their skin. There were no other vehicles nearby, and there was no prior damage to the sunroof/moonroof of the vehicle. The truck gave no warning or signs of malfunction prior to the event. The sunroof was closed, and all windows in the vehicle were closed. On Monday morning ([xxx]), I took my truck to the local Ford service center, and they inspected it, shocked at the results. They filed a claim that Ford denied because the windows are not covered by my extended warranty. They wanted to charge me $ 4,000 for the repair/replacement of the glass and track. I have been on the phone with Ford protection and Ford customer service (Aug 6th, 2025), trying to get something resolved, and Ford continues to deny responsibility.

About 1 hour into a commute, I attempted to connect to a call while using the car play function of the sync system. Upon connection, the speakers blasted as loud as they could possibly go, a terrible pulsing static sounds that scared me and the passenger and almost caused us to have an accident. The volume knob was indicating 0 and would not move and I could not lower the volume of the terrible sound. I pulled over and tried to restart the car a few times, but the sound would not stop until I left the car off for about 10 minutes. I've not connected my phone via bluetooth or car play since for fear that the sound may return when I am not expecting it, startle me and cause an accident. Though I am not certain of the cause. After about 10 minutes of the sound, I also noticed that the speakers were getting hot and I could smell the electronics or wiring overheating. I have a video of the sound but the dealer could not replicate it.

Truck has been at Ford dealership since July 9th for this recall. After updating the computer as mentioned in the recall, a “trailer brake fault” was displayed and we were left with no trailer brakes while towing our camper. It has beyond a “reasonable amount of time” to get this safety issue fixed. Compaign recall number: 25s15/25v132.

A few months ago, my 2021 f150 started sending me repeating dashboard messages that there's a front camera fault and service is requested followed up with a message about how the pre-collision assist is not available. It's bad enough that this is a problem on a late model vehicle, but my real gripe is that the message repeats over and over non-stop, with a repeating chime to go along with it. It is a terrible distraction for a feature that I've never needed in a vehicle. I asked the Ford dealership about this issue, they said that it would be several thousand dollars to replace and calibrate. So now I'm stuck with a truck that chimes and flashes messages, over and over, every time I drive it. I can provide video evidence of the issue.

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 into neutral due to the complete loss of power. The hazard lights would not turn on due to the complete loss of power. If this happened on the interstate, I would have very likely been in a serious life threatening /taking accident. This is as big of a near miss that I can think of, and only because it happened on a neighborhood street when no other vehicles were approaching from in front or behind. This is a major safety issue. Has the problem been reproduced or confirmed by a dealer or independent service center? -the vehicle is currently at the dealer for a diagnostic review. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -in process at the Ford dealership were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -the vehicle had been running for 30-45 minutes prior to this happening without any warning lights / symptoms.

My gear shifter was sticking, making hard to shift gears. I had to pay $1100. 00 dollars to get it fixed. The truck has only 37,000 miles. This seems like a defect not a random component gone bad.

The side rails that come out when door is opened to assist with getting inside the truck does not work properly. It has come out and will not go back in. The door is closed and I have to drive the truck with the rails hanging down. That is a hazard.

My transmission has failed and is slipping it's jolting and has cling sound. The rpms indicator fluctuates. Sometimes stays on 10 speed.

Since my truck was brand new, the infotainment screen very often blacks out so that I can not see navigation, back up camera, radio, etc. It keeps resetting itself until it comes back on. A couple of times when I brought it in for service I asked them to check it out and it was always "seems to be working fine". Today I backed into a sign as the back up camera was frozen and I did not notice that it was not real time. After I hit the sign, the screen went black and then the Ford insigna came up and it repeated 3 times and then everything was fine. Ford service has never been able to fix it as the don't see it when they start the vehicle. I will start taking videos with my phone. Anyway now that the extended warranty just ran out, it is getting worse where it happens almost all the time. I talked to some friends and they tell me they have the same issue so you need to be aware that this dangerous situation might be a common problem.

The rear axle hub bolt on my 2021 Ford F-150 powerboost failed to meet design safety standards and is subject to recall 23s65. The vehicle is currently at a Ford dealership and is available for inspection upon request. My safety was put at risk because the bolt can shear off without warning, causing the rear axle shaft to disengage. This can result in sudden loss of propulsion or vehicle rollaway, especially if parked on an incline. Ford has acknowledged this risk but has not made a final repair available for powerboost models. I was not offered a loaner, and I cannot confirm if the vehicle is safe to drive. The problem has been confirmed by the dealership. They told me they are unable to perform even the interim repair until at least July 22 and that there is no eta at all for the final fix specific to hybrid (powerboost) models. The vehicle was inspected by a Ford dealer but not by Ford motor company representatives directly. Ford customer service has failed to provide any meaningful support or confirmation of safety. There were no warning lamps or messages prior to the recall. Ford states the failure may occur without symptoms, which makes the defect more dangerous. I have not personally experienced a failure yet, but I'm being asked to either drive the vehicle in this condition or go without transportation indefinitely.

Rear view camera and the 360 camera does not work at all on my 2021 Ford F-150 it says return to dealership for repair.

I was driving my 62000 miles truck on the highway while trying to pass another car which was driving slower, I was at a speed close to 60mph, the engine ran at 5000 and I lost power, a truck just behind me has to swerve to avoid me. No warning lamp was on. No accident occurred hopefully. Went to the dealership and they said that the issue was caused by a defective transmission. Ford had denied to pay for the repair or replacement as the warranty is a only covering the first 60000 miles.

I drove approx 50 miles. Parked, return to truck approx 45 mins later and the battery was dead. No turn over at all. Called aaa purchased new battery which was installed roadside in a parking lot. Upon starting the engine I noticed the ac was not blowing and hot air only if it did. I took vehicle to mac maik Ford. I was told the ac was in need of new parts and $freon$ ? the repair was approx $4500. 00 then add freon fee. I declined. Returned to gullo Ford where I purchased truck and I was told it would take up to a week or more to leave it for just evaluation. They offered a rental vehicle for $65/ day . I was not going to pay$800 in rental fees to wait for an evaluation not even repair?! I returned home in the hot truck and stopped by the private garage in neighborhood. Rustys. They kept it half a day&said upon investigation numerous complaints were filed for the same situation. Rusty stated he would order the part and be completed in abt 3-4 days max>. Ok, order parts. I get in the truck after the small independent garage guys went over it in 1/2 a day & the ac was working. I again refused to leave it at rustys garage. He said he would order the part because site stated numerous ppl had the same thing I had had. Battery dying and a/c malfunction combo. If I had not been informed of the recall potential of the type of reoccurring incident on vehicles like mine I would have been ripped off for thousands!! rusty ordered the part but kept part b/c my ac is good but tapping the battery? 3 days after his diagnosis being different from the dealers my a/c is still witking. . However, the potential remains high for ac failure at this point to reoccur. There is obviously a malfunction in the a/c that kills the battery. I am not the only person with this issue. This warrants a recall on whatever it is that drains the battery and kills the a/c function and lets the dealers profit! please address & recall. Bust the dealers who want thousands to fix this too! recall the ripoff. . .

The step bar that come out whenever a door opens ro assist with getting inside the truck does not come out everytime. Sometime the bar will come down once door is open and remain down when the door closes. The bar is supposed to go ba k in once the door is closed. This happens several times in a week.

Had ac on on the way out of town when the air from the vents smelled like mold and mildew and the smell is not healthy for any human beings and the ac drain has no elbow on it witch is the cause of water getting back into the system the smell made me sick and called Ford and was told I would have to pay for it since it was pass 3 years truck has 29k miles on it should not be making that smell at so little miles it is a health hazzard.

I was driving to in the morning and my entire rear window randomly shattered and glass flew everywhere in my truck and on me in the drivers seat.

The factory-installed panoramic sunroof mesh air deflector is causing a water drainage issue. Water accumulates in the main channels, saturating the mesh and allowing it to retain moisture for an extended period. This prolonged dampness leads to mold growth, creating a health concern due to the mold odor inside the cabin after any rainstorm.

This recall has been out since August of 2024, this recall is extremely serious and should not be taken lightly, a remedy should absolutely already be developed!!!!!!!!!! this can cause serious accidents resulting in death especially at a high rate of speed!!!!!! solve this issue!!!!!.

The back window of the panoramic sunroof exploded, and spider webbed across the entire glass windowpane while going down the road. Pieces of glass shards immediately fell all over the truck interior and then a piece of glass fell out of the middle of the sunroof panel. I notified my Ford dealer immediately and took it in for observation and review. I also took pictures of the glass right away.

I did not have an incident. However, we have been waiting 7 months for a remedy. I am scared to drive the vehicle until it is fixed. How long do we have to wait for a solution?.

On numerous occasions, with increasing frequency, the truck has suddenly not responded to pressing the throttle pedal. I have not figured out the exact situation that makes it happen. From the best of my knowledge I am not sure exactly what induces the issue. I have noticed it several times where the truck goes from a mid range rpm (consistent with normal driving conditions) then after the brake or natural deceleration occurs and you go to reengage the throttle pedal the truck does not respond. There is a very extended delay to any speed increases. This has been extremely dangerous when making left turns through traffic as the truck does not respond and leaves you in harms way. It has been happening several times a week now and I have read numerous reports of the same thing on forums. I see no warning lights or pop ups that can support a large issue.

My cluster gauge is turning off while I’m driving and turning on after by itself. It happened too many times maybe 20 times in last 2 months. When this happens I’m loosing all my settings I have done before. While it’s off I can’t see any information including my speed and distracting me. I share this issue on platforms and too many people having same issue. I found too many video on youtube about exact same problem. It happens on the f150 trucks with digital cluster gauge produced after 2020 and even brand new ones having same issue still problem is ongoing. Ford and Ford dealerships aware of the problem but they aren’t doing anything about this and they say it’s well known issue.

During cold weather the driver and both back door locks will and cannot be locked or unlocked and the doors cannot be opened from inside or out if locked. Temperatures under 28 degrees fahrenheit the locks become sluggish. Below 20 fahrenheit the locks and door will not function at all. The dealer ship has checked out this issue but say that if replaced with current parts the problem will most likely continue. With this issue I have been locked in the car twice and had to exit the passenger door (which works for some reason). I now leave the truck unlocked which leaves me open to theft.

Rear backup camera and distance sensors stopped working. The issue is intermittent this issue could have resulted in an accident or injury/fatality due to no image sensor information no dealer involvement at this time no outside inspections at this time no prior warnings or messages were given before the failure.
