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

There is a fairly common issue where there are bolts at the end of the rear axles (P/N 19S426) have the bolt head shearing off and rattling around inside the wheel. I had one such broken bolt. The issue is large enough that hundreds of owners are reporting this on Ford Truck forums, namely on the 2021 Ford F-150 Powerboost with the Max Tow Package like mine. Ford needs to recall this.

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

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.

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.

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..

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.

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 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.

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.
