2021 Ford F-150 Hybrid complaints

I brought my truck in for routine maintenance oil change & tire rotation and was notified by the dealership that the right rear axle bolt was broken off and that the axle needed to be replaced and that it wasn’t safe to drive it until it was replaced well here’s my problem I didn’t know it was broken or unsafe to drive and had I not brought it in for the oil change early I would still be driving it like that this is a serious problem which could result in a loss of control and accident I’m not the only one that has had this happen I’ve researched it a little and found multiple people on an F150 forum that have had the same experience

Audio system malfunction that resulted in deafening random electronic noise levels that would not stop until the battery was disconnected for a long period of time. I started a thread online (link below) and there are numerous others with the issue. There are multiple videos showing the issue. Some have reported a burning smell so there could be a fire risk as well. (https://www.f150gen14.com/forum/threads/dangerous-b-o-sound-system-issue.9254/) It really is loud enough to cause a crash and I believe it's just a matter of time if it hasn't already happened. My ears were ringing for several hours. To date Ford hasn't provided any resolution beyond just extending my factory warranty. The vehicle was taken to the dealer for a full week with no resolution - again, same as several others.

Passenger rear axle bolt broken. This seems to be happening only on Max tow equipped vehicles, LOTS of them.

When in regular use of this hybrid Powerboost F150, the truck lurches forward on electric motor power as if you just got rear-ended. This happens every single time you have to come to a stop for more than 5 seconds. The only way to avoid this issue is to drive in"tow/haul" mode which keeps the truck's engine running. This defeats the purpose of a hybrid truck, and you have to remember to switch the running mode from normal to the haul/tow mode. This lurching had to be causing extra wear and tear on the drive train parts. Apparently the problem is a faulty "Transmission Fluid Auxiliary Pump". Many of us on the Ford F150 forums are waiting on our dealers for this back ordered pump. Apparently Ford continues to build vehicles while falling to provide a replacement pump? I am concerned as to the design of this pump as well. My"new" truck only has 7800 miles on it, a little over one year old, and the pump is defective. Is this going to be a reocurring problem? This is a safety issue and should be addressed ASAP. Thank you for your attention to this matter..

Rear differential, passenger side axle bolt broke off. I removed the right rear wheel after hearing a metallic noise while braking to inspect, as soon as I removed the wheel a broken head bolt and washer fell out and you can clearly see the other piece of the bolt is still in the axle shaft. I am not sure if this bolt breaking off could cause loss of wheel or axle. But now my brakes are making noise, I believe as a symptom directly related to this issue. I looked up 2021+ F150 forums and customers with this max trailer tow axles are experiencing the same thing. I took the vehicle to the dealer today to get this inspected and am awaiting an update. The only indicators of a problem was loud metallic noise while braking, and a slight ringing sound while driving without braking. It was all sounding in the rear of the vehicle.

My 2021 Ford powerboost Lariat lurches forward when at a stop in normal drive mode, it feels like someone rear ended the truck.This is a safety hazard if I don’t have my foot pressed hard on the brakes I could be launched into on coming traffic or hit someone crossing the street.

Complaint 1: Mar 14,2022 Manufacturer Recall Number22S12 NHTSA Recall Number22V-142 Parts for recall has not been made available yet, promised for 2nd quarter. We are not into 3rd quarter. How can Ford still produce new trucks if parts are not available to fix existing trucks on the road as it is a safety concern? Complaint 2: Error code P2C44 - requires replacement of Auxiliary Battery Insulator from Ford's internal doc SSM 50976. Was told part is also backed ordered for 45 days. Again how can Ford build new trucks if parts are not available! Please make them fix existing trucks on the road first before new trucks are built! What good are warranties when it takes months to fix.

My vehicle has the 3.5L powerboost motor and it has been leaking coolant from the egr cooler since I bought the truck in 01/2022. This has caused my vehicle to overheat and has left me stranded on busy highways.

Heard a metal grinding coming from the rear axle on . Took it to Ford dealer maic Haik in Georgetown Texas. The found the axle bolt had sheared off. It is in the shop currently waiting a warranty repair and the shop indicated this was not the first one they had seen.

Myself and several other individuals with 2021/2022 Powerboost F-150s are experiencing an issue where the whole vehicle will lurch forward as if hit from behind after coming to a stop. This can result in the truck hitting the vehicle in front of you if you are in tight traffic.

13800 miles, broken axle/wheel bearing retaining bolt. Screeching noise. Bad wheel bearing. Dealer will not replace wheel bearing because they do not correlate the broken bolt to a bad wheel bearing. Leaving me with a bad wheel bearing that I consider prematurely worn out and is making a clicking sound. Dealer says they cannot replicate the noise so will not investigate further

In May 2022, the passenger side right rear axle bolt sheared off creating a squealing/grinding noise from that wheel. The only thing holding the wheel onto the axle were the brake caliper bolts. The repair involved a new axle. In early Sept 2022, the driver side rear axle bolt sheared off with the same results. The vehicle is now in the shop waiting for the parts to arrive. Dealer advised that this is a serious safety issue and requested that the vehicle be towed to the service center.

The rear right axle bolt sheared off at 12.5k miles. if you google "rear right axle bolt 2021/2022 f150" there are THOUSANDS of people with the same issue. Thank god I heard the sound as it rattled around. I can't imagine the danger of driving down the highway at speed with my children in the back and the tire ends up sliding off. Ford is pretending this does not require a recall, yet tens of thousands of people on the forums have the same issue

Passenger side rear axle retention bolt sheared off in normal driving conditions (no incident). Heard a knocking sound in rear wheel, removed center cap and found the axle retention bold broken off with bolt head and washer bouncing around in the center cap. Dealer says the part has been redesigned and will be replaced under warranty. Was told vehicle is unsafe to drive.

The driver side rear axle retaining bolt sheared off rendering the truck not drivable. The truck is at the Ford dealership I purchased it from waiting for a replacement part. This is such a common problem that the axle shaft is on back order, so I am without my truck until the parts are available. Upon researching online I have found this to be a common problem that Ford is very much aware of but have not taken action to correct.

Rear axle bolt sheared off. Per Ford axle must be replaced

My truck is 2021 f150 powerboot. I got message “ stop safely now” and unable to start the engine. This is happened twice . The first time is about 20K miles, the second times is happened on 8/13/2022 at 55k miles. I brought my car to dealership for first time and service manager told me they waited on ford company for instruction. But no one call me for recall or advice. Please help us. Thank you

The contact owns a 2021 Ford F-150. The contact stated that while driving at various speeds, a humming and tapping sound was present coming from the rear undercarriage of the vehicle. The vehicle was taken to the local dealer who diagnosed that the underbody insulator was faulty and had caused damage to the driveshaft. The vehicle was not yet repaired. The manufacturer was notified of the failure. The contact indicated that the vehicle was previously inspected under the NHTSA Campaign Number 21V986000 (Power Train, Structure) however, the vehicle experienced a failure after the inspection. The failure mileage was 26,836.

Drivers side rear axle bolt sheared off. Noticed noise coming from rear while driving, removed wheel, bolt head and washer fell to the ground. Bolt head and washer we’re both retained. Local dealerships (albuquerque, NM) do not have the capacity to diagnose the truck for a minimum of two weeks. The structural integrity of the axle and drivetrain are in question.

Broken retaining bolt holding the wheel on the right rear axle. Dealer said too dangerous to drive so they replaced axle. Dealer has old axle and broken bolt. This problem exists in the 2021 F150 Powerboost truck with 9.75 in 3/4 floating axle. Several postings on F150 forum of this happening to others with same truck. Nothing holding rear wheel on except brake caliper if bolt brakes and wheel wobbles loose. When service tech takes wheel off to rotate tires the broken bolt falls on the floor.

Rear passenger axle bolt sheared off.

When drive train goes into electric drive mode, the vehicle will jump/lurch/bang after stopping like I was hit by another car pretty hard. This will only happen when the engine either goes into hybrid electric mode or engine turns off after a stop in sport and other modes. It will not happen in tow mode where the engine stays on. The issue is the aux pump on the transmission going bad, this was found by dealer and part is on national backorder. Truck can jump a foot forward at red light if foot is not smashing the brake pedal down - seems to be an issue popping up daily on forums from others having issues.

The contact owns a 2021 Ford F-150. The contact had received notification of NHTSA Campaign Number: 22V193000 (Electrical System) and the vehicle was taken to the local dealer and the integrated trailer brake control module software was updated. The recall repair was completed. The contact stated that while starting the vehicle, the trailer brake module fault warning message was displayed and turn signals were blinking rapidly. The contact called the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 12,000.

The wheel hub axle bolt sheared off under normal conditions-dealer was unaware this was even an issue and told me the bolt they found within my wheel assembly and its attached washer was picked up off of the road (road debris) that they removed it and it would not grind anymore. I did basic research as an uninformed consumer and within seconds learned this is an issue on hundreds of other power boost pickup trucks. There is extensive documentation online regarding this issue. I called my dealer who has yet to respond to me. This is a major safety issue-the only thing holding the wheel on is the brake caliper. With as many documented cases as I can easily see online-the fact that my dealer is not aware of this indicates Ford has done nothing about it. This should be a recall. Please advise.

The contact owns a 2021 Ford F-150. The contact stated that the gear shifter seized while shifted in park(P) and was unable to shift to the intended gear. Additionally, the gear shifter fractured when the contact forcefully shifted out of the park(P). The contact had been waiting for the vehicle to be towed to the dealer; however, the vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure and was forwarded to roadside assistance. The failure mileage was approximately 1,500.

Truck does not always does not always downshift to a lower gear at a stop and instead remains in 8th gear. This poses a safety risk do to a lack of acceleration and also causes an unanticipated sudden jerk when it does finally does engage in a lower gear.

Left rear axle bolt sheared off into the wheel spontaneously. It is available for inspection. . Currently at dealer right now for repair. Dealer indicates vehicle not safe to drive due to potential for loss of wheel, brake components and wheel hub/axle during travel. I have not experienced loss of a wheel while driving luckily. There were no warning lamps/messages etc. No symptoms of the problem prior to failure were noted. The only sign of an issue was loud squealing from the left rear wheel when brakes were applied or when turning the steering wheel slightly either right or left. Refer to the following for additional cases. https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared. No TSBs have been issued on this based on database search.

The vehicle was unlocked, and I was in bed. At 1:35AM the tailgate just opened without any input from me (the remote was in another part of the house), and I received an alert from FordPass that the tailgate has been opened. I immediately checked the area outside and it was dark as I live in a very rural area. I turned on the all zone lightning, and nothing was seen. I closed the tailgate remotely, and I heard it latch properly.

The contact owns a 2021 Ford F-150. The contact stated that the front windshield wipers failed to operate properly. The contact stated no warning light was illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the windshield wiper motors to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 2,000.

I took the vehicle in for a tire rotation and oil change at approximately 18,000 miles. The dealer informed me that the passenger side rear axle bolt had sheared off and that the bolt had to be drilled out and replaced. The repair did not solve the problem and now the axle has to be replaced.

On several occasions, the cruise control has failed to disengage when applying the brake. It does not happen every time but it is unsettling when it does happen. When it does happen, the engine and the baking system are working against each other.

Outer axle bolt sheared from passenger front axle assembly. Both passenger and driver axles had to be replaced because of grinding noise and nut/bolt found in center cap of wheel.

When Blue Cruise is activated and the vehicle takes a semi sharp turn it does not straighten back out and attempts to continue into oncoming traffic. Does not seem to happen on the interstate, I believe its because the curves are not as sharp. This is a frequent issue that happens continuously. Brought it to the attention of the dealer when I had the recall performed. They recommended a tech ride with me to reproduce it, but it was not offered at time of pickup. You can completely take over steering, but there is resistance. I just want this to be reported and hopefully a resolution comes up at some point.

The contact owns a 2021 Ford F-150. The contact stated while driving approximately 25 MPH, the sheared axle bolt became faulty. There were no warning lights illuminated. The vehicle was taken to several dealers who diagnosed the same failure. The vehicle was repaired several times however, the failure reoccurred. The manufacturer was notified of the failure. The approximately failure mileage was 9,622.

Very loud grinding sound coming from the rear axle/ wheel hub area. Then a clunking as if something was loose or rattling around inside the rear hub. Turns out the axle bolt has sheared off.

Axel bolt sheared off for rear drivers Axel. Only part holding tire on was break rotor and caliper. The dealer found during a routine oil change/tire rotation. The only symptoms was shifting hard when driving, and slight rattle when driving as the bolt head was caught in the wheel center.

The Check Engine Light illuminated and brought to Ford dealer. Was advised it has code P237C which is a failed Exhaust Heat Exchanger, dealer ordered part # ML3Z5A212W. There is no coolant leak visible from the failed part. But driving down the highway around 70mph, the vehicle suddenly decelerates and goes into Reduced Power Mode, throttling back the engine. The reduced power mode is displayed on the instrument cluster, but it is still startling to have the vehicle decelerate, especially at highway speeds in traffic. And would be more problematic with a trailer in tow. My Ford dealer has the part on order but Ford states it is on back order with no expected delivery date. Very disappointing from a quality stand point, but a concern as well from a safety perspective. I know others have had a similar issue which is also accompanied by a coolant leak, which I do not have on my vehicle but I am concerned and continue to monitor for leaks and watch the fluid level. I do not have any photos of the valve. Unexpected reduction of engine power in my opinion is a safety issue, especially at highway speeds or when towing. Thank you for your review of this issue.

UNKNOWN Our F-150 was hit by a driver from a side street. The whole passenger side was damaged, front fender replaced, front door replace, post repaired, back door replaced, back panel of truck replaced, and back wheel. The long step was pushed up and under vehicle. It was replaced as well. The side airbag did not engage. I was thrown around in the passenger seat. I experienced a contusion on my right knee and three days later diagnosed with side impact whiplash. The truck was declared not safe to drive while we were trying to get estimates for repairs. They were concerned that the airbag didn’t go off and the door was not closing correctly even after they tried to tweak it. Our truck was towed off by the insurance company to a secured site until we could get it towed for repairs. We were never told why the airbag didn’t go off.

2021 FORD F150. CONSUMER WRITES IN REGARDS TO SAFETY RECALL 21S56. THE CONSUMER STATED THE VEHICLE BEGAN ROLLING WHILE IN PARK AND THE ENGINE POWERED OFF. THE VEHICLE STRUCK A TRASH CAN. THE VEHICLE WAS SCHEDULED FOR AN APPOINTMENT TO BE DIAGNOSED.

The F150 7pin flat The brake pin does not operate properly, fails to get signal from brake pedal. While pulling 6000lb trailer the trailer brakes failed to operate. I currently have a dealer app. On Feb 23 for a safety recall on this truck. They told me they would look at 7 pin at that time.

They have had this recall since Dec 16th and I have taken the truck and called the dealer several times and they said that Ford has not remedied this recall yet. It is a huge issue and they aren't doing anything about it, several online forms have cited this exact problem with their truck yet Ford is not fixing it.

Brakes failed to stop vehicle when entering my garage. Vehicles brake pedal went all the way to the floor board while truck continued to roll crashing into garage wall damaging personal items stored in garage as well as drywall, studs, and hair-line vertical cracks in exterior brick veneer. I have security video of the complete incident.

My trucks integrated brake controller will not consistently control the electric trailer brakes. I plug in the trailer and get confirmation that it is controlling the brakes by manually testing them while rolling and at some point during the trip it stops controlling them without warning. I have tried all methods to be sure the 7 pin connection is seated properly and I am sure it is. I have a 7 pin tester and when I check the electric output at the plug it lights up the circuit (BK) for the brakes. When traveling and I realize I no longer can control the trailer brakes, I pull over and unplug the trailer, plug in the tester and when squeezing the brake controller it will not light up the circuit marked (BK). If I leave it disconnected and shutoff the truck for 15+ minutes and reconnect, it works again only to stop again at some unknown point. There is obviously a seriously dangerous issue here. I have taken it to the Ford dealer and they can't find anything wrong. When it resets you can't duplicate it until you tow for an undermined distance for it to fail again. I have searched the internet and found many people with the same issue and no one has been able to get it solved by all manner of efforts including many efforts at Ford dealers and electrical shops. This form asks for the date it occurred. It started as soon as I took delivery with 5 miles and is ongoing.

The contact owns a 2021 Ford F-150 Hybrid. The contact stated that while driving the vehicle, several safety features would not operate as intended. While driving in reverse, the rear cross-traffic alert would sometimes malfunction and not alert the driver that a vehicle or an object or pedestrian was near the rear of the vehicle. Occasionally, the message "inoperable" was displayed. Also, the forward-collision warning system would not activate when driving too close to a nearby vehicle or object. In addition, while driving, the adaptive cruise control was activated and the vehicle ahead reduced speed however, the adaptive cruise control deactivated instead of reducing speed causing the driver to press the brake pedal to avoid a collision. The vehicle was returned to the dealer who attempted to perform the software updates however, the updates failed to fix the vehicle. The manufacturer was notified of the failure. The failure mileage was 1,000.

The contact owns a 2021 Ford F-150. The contact stated while driving 36 MPH and approaching an intersection, the brake pedal was depressed and went to the floorboard. The vehicle continued through the intersection. The anti-lock brakes warning light then illuminated. The vehicle was towed to the local dealer however, the mechanic was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure however, no further assistance was provided. The approximate failure mileage was 1,500.

2021 F-150 Powerboost giving "Trailer brake system fault" when not in use and has never been used. Additionally getting the "Key not detected" alert when key in truck. Battery in fob has been replaced and tested to be good. These errors have no known trigger mechanisms to repeat. Just happen on their own. I am becoming increasingly concerned if these can continue to worsen over time. Dealer says they havent really seen either issue. Truck was pruchased 11/17/21 and currently has 1998.5 miles.

The trailer brake on my truck is not working consistently. When coming down a snowy mountain pass two days ago, the bake controller disconnected (after working for about 5 hours). This is incredibly dangerous and due to the fact that I am on a cross country road trip and all dealers are booked months in advance I have not been able to get any information from Ford. I am going to post links to other people having this same problem. This has happened since the truck was purchased. This is an incredibly dangerous situation and I would have expected more from a Ford Truck. I believe based on these other peoples experiences that the issue is with the Powerboost Hybrid specifically. Motor Trend even noticed this in their review: Software Struggles We also intended to evaluate how much the electric motor's torque helps with towing, only to be thwarted by another bug, this one in the trailer brake controller. No matter what we did, the integrated trailer brake controller would not activate the trailer brakes—even with the gain all the way up. We verified the issue was with this F-150 by hitching the trailer to another truck, where the trailer brake controller and trailer brakes worked fine.
