Check engine light on . Ford says exhaust heat exchanger bypass valve. I see online multiple people are having the same issue . Seems to be a common issue with this vehicle . They are saying it’s not a part of the power train warranty although it’s attached to the power train . This is a safety issue. With the amount of posts about this issue I’m surprised it isn’t a recall already.
2021 Ford F-150 Hybrid transmission complaints
Page 3 of 5: complaints 41 to 70 of 129, newest first, as owners wrote them.
The contact owns a 2021 Ford F-150. The contact received notification of the federal safety agency Campaign Number: 23V896000 (Power Train); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. VIN tool confirms parts not available.
While operating the vehicle, I shifted into park, using the console shifter. With no warning, the vehicle malfunctioned. The console shifter indicator light started blinking next to the "P" and it would not let me shift back into gear. I turned off the vehicle and tried to restart it in the hopes that it would clear the error. The vehicle engine would not start, and told me to shift the vehicle into park. I was unable to shift the gear into park or any gear. A tow truck driver came and we were able to force the vehicle into neutral for towing, but the vehicle's parking brake engaged and would not disengage. Every time we turned off the parking brake, it immediately turned itself back on. Thus, we could not push the vehicle into a better position for the tow truck to get the vehicle and the tow truck operator had to drag the vehicle with its back tires not turning. At the Ford dealership, a service employee inspected the vehicle and said there was no physical damage to any component and that some kind of electronics error had caused the fault. He said it was a known issue with F150 transmissions and that a Ford service bulletin indicated a 6-hour "module" reprogramming process was necessary to make the truck operable. He said that it could recur. I spoke to Ford customer service. A representative there confirmed that this is a known issue with F150 transmissions but that no recall had been made. She also stated that Ford did not know why it happens and that, even after being "reprogrammed", it could happen again. Based on my experience and discussions with Ford, the F150 can suddenly become inoperable and (because of the parking brake) immovable. Thankfully, the transmission error occurred for me in a safe location near my home. It could have been very dangerous had the vehicle become immovable in an unsafe location or far from home or help. I am concerned it will happen again. The vehicle is currently at the Ford dealership in Grand Ledge, MI.

At a stop, in electric mode, truck will lunge forward as if you were rear ended. Most of the time, transmission failure will occur after some time due to this lunging forward, and it has happened to many truck owners. Electric auxiliary transmission pump tends to be the cause .

There hasn't been an incident yet. But, I want a record of this somewhere. I'm assuming there may be an incident in the future; and, I'm concerned about that. Either an incident with my truck or an incident with the 100s of thousands of Ford and Lincoln vehicles from 2017-2023 that have this issue. The issue is Ford SSM 51939 - a whining noise coming from the bellhousing and the front of the transmission fluid pan. I have taken my truck to a dealership. I have called Ford about this. I have researched extensively online. I have called the federal safety agency. I have emailed the Office of Vehicle Safety Compliance. I am now filing this report online. The safety issue? For me, I'm now having to wear EARPLUGS when driving my vehicle. For others, they have been told to turn up the radio. I am now hearing the noise all the time -- believe it or not, even sometimes when I'm not even in my truck. Ford needs to address this. They send me to you. I don't have the 'option' of TRADING IN MY VEHICLE...others don't either. What am I to do? When something serious happens because people are remedying this themselves...it will be a very sad day. But, maybe only then will Ford do something. I don't know what else to do other than call Ford everyday, and email every agency that may be able to apply some pressure. Sadly, I have a full-time job...and this is really frustrating for me, in more ways that one. Hope you have a nice day!

If you pull onto a road and try to accelerate, the vehicle is unresponsive. The RPMs will increase, yet the vehicle drive train (10 Speed Transmission) is unresponsive for several seconds. This has been an ongoing issue with the vehicle since new and was first reported to Ford Customer service on Jan 2022. Ford has made several attempts to fix this issue, yet the transmission continues to fail with the same issue. This is a critical safety issue that jeopardizes the passengers in the vehicle. Vehicle parking brake engages without notice. At any given time, the electronic parking brake engages without warning and you have to manually release. While sitting at a controlled intersection, on an inclined street, waiting for traffic light to change, with vehicle in Drive, foot on the brake, the electric parking brake engaged. Vehicle shift lever moved to the park position on its own. Vehicle engages it's parking brake and moves shift lever into Park while sitting in traffic is very dangerous. Vehicle shift column failed in drive and vehicle would not move or run. This caused drive train to lock in place, freezing all four tires. Ford had to drag truck onto flat bed with tires locked. It had to be dragged off flatbed when delivered to Ford dealer for repair. They had to put grease down on the flatbed so truck would slide off without tires rolling. While at the dealership, the mechanic had to manually disconnect the calipers in order to move vehicle. The safety backup features failed and would not release wheels (lever under steering column).

The contact owns a 2021 Ford F-150. The contact stated that while her husband was driving 15-20 MPH, the gears locked up. The contact stated that the check engine warning light was illuminated. The vehicle was restarted, and the check engine warning light was flashing. The vehicle was taken to the local dealer, where it was diagnosed that the cam phaser needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and offered to cover 70 percent of the cost of the repair. The failure mileage was approximately 77,000.
My 2021 F-150 Powerboost randomly shuts down on the highway and while pulling out into traffic. When it shuts down the steering and brakes work but the engine is off/no acceleration and the truck displays a warning telling me to "Stop Safely Now". Truck has been look at many times by Ford and every time they give it back to me it happens again. There appears to be either and electrical or software issue but after 3 months Ford doesn't seem to know what's wrong with the truck even though they have reproduced the problem. It has happened over 20 times putting me and my family at risk of getting in an accident.
3.6.2021 - Ford F150 purchased at Battlefield Ford (Ourisman Ford), Manassus VA / registered in CT 7.27.21 – inspected by Torrington Ford, Torrington CT for rubbing sound front left side, nothing found / 6,325 miles 2.10.22 – inspected for same issue / nothing found / 16,000 miles 7.27.22 – inspected for same issue / nothing found / 24,000 miles 12.24.2022 – “Catastrophic failure” of front differential / 34,369 miles. On Christmas Eve 2022 myself, husband and son were driving to family in NY when the truck very quickly started to make a severe grinding sound, became unable to steer, loss of control, and started to produce smoke & fire under the hood. We immediately stopped and got out unharmed. Fire was dripping out of the bottom of the truck and smoke/fire under the hood. We were lucky. Firetrucks came but were unable to do anything. The truck's wheels completely seized up - the tow truck had to skid it onto the flatbed. Repaired at Simmons-Rockwell Ford, Hallstead, PA. Complete new front differential and damaged parts in proximity to the failure (pinion gear, axle shaft, etc). 12.16.2023 – Again hearing a sound in front left side while driving; bring to the shop for inspection. Shop confirms front differential is failing again, per Torrington Ford, (where all maintenance and repairs were completed, except for the first failed front differential in PA). Advise not to drive for safety reasons. 52,922 miles. With both front differential failures - no warning lights or messages. Symptoms - a slight rubbing/grinding noise in the front left side of vehicle; “rough” sound while driving. 1st front differential – inspected at 6,000 miles, 16,000 miles, and 24,000 miles. Failed at 34,369 miles. 2nd front differential – inspected at 52,922 miles, failing differential, advised not to drive. Dec 2023 – Buy-back claim filed with Ford Motor Co. Denied - "outside of the 18-month warranty period for VA Lemon Law". Clearly, safety is not a guiding tenet for Ford Motor Co.
On November 29, 2023 I took my 2021 F150 to Larry Miller Ford for servicing and repairs related to Recalls 22S71 and 23S35. When the tech was rotating the wheels he discovered that the axle shaft bolts were sheered off on both the left and right rear wheels. The service manager called to tell me that this was a serious safety issue and that only the brake rotors were preventing the wheels from falling off the truck. The service manager told me there was a "Customer Satisfaction Program 22B34" issued by Ford, but no Ford Recall relating to the problem. Larry Miller Ford has replaced both axles and axle bolts. I am waiting to find out if there is damage to the rotors, calipers or brake pads, a concern since the sheered off bolts were rattling around within that area since breaking off apparently between service visits. I strongly believe Ford should be required to issue a recall on this problem. I never received a notification on CSP 22B34. Had it not been for my tire rotation, the wheels could have fallen off at highway speed.
I heard a scratchy rattling sound around 35-36k miles at very low speeds. Eventually narrowed it down to the passenger rear wheel area. I took off the wheel to inspect the area and the head of the axle bolt fell out. It looked to have been yielded from over torquing or something. But I was shocked! I have no idea the actual period of failure. If I hadn’t rolled my windows down for the nice weather, I probably wouldn’t have heard it. I checked and there has been no recall or anything sent to me that this is a problem. I tow a camper with the family and if the axle failed while doing so, it could of killed us. Very unhappy that Ford has not recalled this. There are many others on a Facebook group that have had the same issue. It needs to be Remedied.
Vehicle came to complete stop in traffic with warning light "stop vehicle" would not restart. Taken to dealership. Dealership replaced ecu and some switches to power bank and wiring harness behind headlight. Vehicle was returned 1 week later Drove it 2 days later for 10 miles same thing happened, Ford towed it to another dealership where they cleared codes, and they said they can't replicate, Vehicle was returned after a week. 2 days later I drove yo work and again iy happened stopped in middle of road blocking traffic. Was towed by Ford to dealership where they found over 20 codes, said they can't fix. Ford and selling dealer towed to selling dealer, where they cleared codes and said they can't replicate. I refused yo take Vehicle on fear of getting in severe crash when Vehicle stalls and dies in heavy traffic again. I signed title and sent it to selling dealer, they told me that fordwill not let them buy it back. Do I don't have my money or a truck now
My truck has the Maximun payload axle upgrade. The axle bolts on the end of the shaft have broken. I first notice squealing sound of metal from rear of truck. I searched on line for the symptom and found the problem. I then removed passenger rear wheel to verify broken bolt. I took my truck for service to Morries Grand Ledge Ford in Michigan. They verified the problem, told me it was not safe to drive and have ordered parts. They also informed me that the defective axle is not covered by recall on my vehicle. The service representative did confirm that there are recalls for the same axle but not my vehicle.
Transmission is not working correctly. When truck comes to stop, after 3 second there is a strong jolt that feels like the vehicle is being rear-ended. Error code indicates Auxiliary Transmission Oil Pump. Other owners have had same problem and it was Auxiliary Transmission Oil Pump. Dangerous condition because could cause issue at intersections or hitting pedestrian or other vehicle. Part is apparently backordered so cannot even be fixed.
In the last year I have taken my F150 powerboost in Autonation Ford Orange Park in Jacksonville, Florida twice for recalls. For recall the federal safety agency # 22S26/22V250 the service department said they were ordering parts and would contact me when they arrived. Never contacted me, even after follow ups. I have recently taken my there for recall the federal safety agency 23S35/23V509. They have not contacted me.
- The component that has failed is the right rear axle and retaining bolt (the axle retaining bolt sheared off). The vehicle is currently at the dealership (The Ford Store San Leandro, in San Leandro, CA) waiting for replacement parts. Unknown if the vehicle is available for inspection. -To my knowledge my safety was not at risk, but the vehicle is being retained by the dealership because it is deemed a safety concern. -The broken axle bolt was found by the dealership when they were investigating a noise complaint. -The only symptom that was present was noise.
Gear shift lever jammed in reverse and could not be changed. With battery powered motor, the vehicle could possibly take off and cause damage or injury. Vehicle is new and still under warranty. Dealership is evaluating the problem
The contact owns a 2021 Ford F-150. The contact stated that while driving at an undisclosed speed, he heard an abnormal scraping sound coming from the rear driver's side of the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the driver's and passenger's side rear axle bolts had sheared off. The vehicle was repaired, but the failure reoccurred. After investigating the failure, the contact related it to Customer Satisfaction Program: 22B34, but the vehicle was not included. The manufacturer was notified of the failure but referred the contact to the federal safety agency Hotline for assistance. The failure mileage was 20,000.
The driver's side rear axle bolt sheared off over the course of normal driving. Ford is aware of this problem, advises to not use/drive the vehicle, yet no recall has been issued. Without a recall, getting this issue fixed will take weeks/months and Ford should pay for a rental vehicle since this is clearly a manufacturing defect.
Rear axle bolt broke off
This is the 4th time since purchasing the truck that this event has happened with time having the most severe results. When shifting from reverse to park the shifter goes into park and jumps back into reverse. First event (after exiting the truck) the truck rolled into a shipping dock breaking a taillight and buckling the rear bumper. Next two I had one foot on running board and one foot in the truck ant was able to hit the brake stopping the truck. This fourth event one foot was on the running board and one on the ground. As truck went back the door flattened me to the ground and the front tires rolled over both of my legs. The truck rolled up an inclined parking lot, across a busy road and down a bank. I was driven by ambulance to the hospital and then transferred and airlifted to trauma center at Ruby Memorial Hospital. After the second event the local Ford dealer said they could not duplicate the event. The brakes do not hold even though they are depressed and set when the shifter is shifted.
The axle retaining bolt that retains the floating axle to the hub failed and resulted in the floating axle splines at the hub failing. This is a known issue (see Ford Customer Satisfaction Program 22B34) but the recall only applies to vehicles manufactured from May 1st, 2021 to September 30th, 2021. My vehicle had the exact failure described by the recall (including the tell-tale ticking sound before failure). However, the build date for my vehicle is March 17th, 2021. Clearly the recall should be on trucks earlier than the May 1 date. The truck was built at the Dearborn Plant. I am assuming the other axle suffers from the same issue and will also fail.
The axle bolt on both rear wheel hubs has sheared about 1/2 inch down the bolt. This led to the gradual loss of power to the effected wheel hub causing unpredictable handling characteristics as the interface between the axle and the wheel hub degrades due to the fastener being sheared off.
The contact owns a 2021 Ford F-150. The contact stated while driving in electric mode at an unknown speed, while depressing the accelerator pedal, the vehicle failed to accelerate with the transmission in 8th gear. The contact stated no warning light was illuminated. The contact depressed the brake pedal, and the vehicle made an abnormal noise and shifted into 1st gear independently. The contact stated he had experienced the failure 5 times within 2 months. The vehicle was not diagnosed or repaired. A dealer was not contacted. Upon investigation, the contact associated the failure with the federal safety agency Campaign Number: 22V188000 (Power Train) however, the VIN was not included. The manufacturer had not been informed of the failure. The failure mileage was approximately 61,800.
Intermittent squeaking noise upon brake tip-in started at about 17,000 miles but performance seemingly unaffected. Then at 21,000 miles noises from became louder and prevalent at acceleration and braking. Noticed issue on Ford F150 14th Generation online forum about axle bolts shearing particularly for those vehicles with Max Tow package and that there was a Customer Satisfcation Program 22B34 to deal with the problem. Inspected hubs and found bolts sheared on both sides. Truck at dealer for warranty repair under the CSP.
The rear rotor/axle bolt was found to be sheered off; the bolt head was located within the hub simply rattling around loose. There is no warning outside of someone possibly hearing the bolt head rattling in the hub as the truck passes by. Thankfully, someone heard mine; otherwise, I would have had no idea the problem existed. This issue has been reported numerous times in multiple online forums, apparently on trucks equipped with the power boost and max towing, and poses an extremely dangerous hazard to the occupants of the truck and to all others on the road. A family member with a similar truck (same model and year) has already had their rear axle assemblies replaced three times (twice on one side and once on the other)!
