2021 F-150 Powerboost Issues

[MR650]

F150 2021 PB Update. Its been a year since I posted here with the list of issues I've seen with my 2021 Power Boost F150. And almost a year to the date my F150 stranded me in the Sierra Mountains with the failure of the right front IWE system. Just got the truck back yesterday.

I needed to take it to a local independent repair for diagnosis and a $1K repair. ford wont cover that issue CXH-03268443-L9B6N4 1) because I'm now at 80K miles and 2) because I needed to have it repaired at the location where it failed by an independent repair shop in Truckee,CA

So when the drivers side front IWE failed last year at this time I had 50K miles on the truck. The failure code was CO 681-77 and the Putnam Dealership in San Mateo replaced the front drivers side IWE module and I asked about doing the front passenger side since the front drivers side had failed, and they declined and so this year I got the powertrain warning in snowy conditions just before Christmas in Truckee. The code this year was the other side: CO 682-77

In addition to these issues I've also had the rear passenger side door sensor replaced and I still have an intermittent warning that the rear passenger door is ajar when its not. Its annoying, seems to happen more in cold weather and it becomes a real problem because it causes the electronic side step to remain deployed in snowy conditions where it accumulates ice and then when it does attempt to close it jams of course because its full of ice and scrapes the side of the truck up.

The net is that after 80K miles and 3 years on the 2021 F150 PB I wouldn't recommend that vehicle and i haven't had more than a couple trouble free months of just basic operation. To me it seems like the truck suffers from 1st year electrical issues that affect multiple systems some are just annoying others more serious since we've lost AWD in the winter 2 out of the 3 years and when it happens, you're wherever you are at that time in rear wheel drive. This time i was in some real snow and ice with the family of 5, 10PM at night.

Here's the summary:
1) multiple power train malfunction warnings: 12/2023 done on warranty - replace front driver side IWE. 12/2024 - replace front passenger side IWE - won't be covered by ford.
2) the 110 passenger side plug doesn’t always provide power, no fix hard to reproduce
3) there was a louder than usual scraping or whizzing sound when coasting down from 30mph to 10mph sounds like some friction on a rotating part. in 12/2023 replace rear axel with some lose or missing bolt and this is now a recall item I believe - with no permanent fix as far as i know.
5) The speakers in the headrest buzzed and eventually the seat was taken apart and someone at Putnam, San Mateo CA adjusted some wiring and that went away
6) The rear passenger side door frequently has a sensor indicating the door is ajar when its not - had the sensor replaced at one point still happens intermittently and usually in cold weather.
7) The 12V battery had to be replaced with electrical issues caused by the failed battery. Think 'i had to pay for that one myself; cant remember.
8) the self driving system is nice but I believe we were originally promised 3 years of subscription and then it was delayed and we got 2 years and then needed to pay for that. Not sure if I'll renew on the next cycle for that.

All in all, I purchased that truck because it was available at the time and I thought I'd use the generator more than i do, so IDK probably wouldn't do it again.

Not sure this belongs in this thread as it seems focused on electronics. I have a 2021 PB XLT which is like a bad relationship. I love it and can't leave it but it's been frustrating after buying new. Today I'm just over 40k miles on the truck. Regarding electronics (compared to others on this thread) to date my issues have been minimal. Under 10k miles I got a message my ABS brakes have failed. Initially being very concerned I field tested on an empty street and the ABS seemed to be working correctly and never saw the message again.

What has me more concerned is at under 20k miles I had to have the transmission on the truck completely rebuilt under warranty by Ford. It was jumping/jerking sometime pretty violently between fourth and fifth gear. After getting the truck back with the rebuilt transmission (and the numerous recalls corrected existing at that time...now there are more) I was told I had to drive the truck for a week or two and let the computer "learn my driving habits" as it somehow adjusts the gear shifting in the tranny according to my driving style. Interesting and certainly not a feature on my bulletproof 2003 jeep wrangler I still own with minimal issues. As of this morning, just dropped my truck in for regular service. However, it's not going to be a "regular" service at all. In addition to regular service (and just over 40k miles I'm now out of warranty) the tranny is now sometimes (not always) jerking transferring from third to fourth gear. I was told they will try to recreate the jerking in the tranny and if it's "from their tranny rebuild" they will cover it but if not I'd be charged. Awesome (insert sarcasm).

More concerning is I now also have a crazy noise coming from my back passenger wheel which sounds like a crackling almost squeaking suspension noise. I've heard much about this rear axle bolt shear and have no idea if that is what it could be. Backing up even at low speed pulling out out of my driveway it's very apparent. Also apparent moving forward from about 15-30 mph when accelerating. Also, seems to come back when depressing the accelerator or applying the brake but go away when coasting and not touching the accelerator or brake. It's very annoying and honestly a little embarrassing with the kids drop off at school in the morning in a nice clean new"ish" truck that sounds like a jalopy pulling in the parking lot.

Anyone else had the tranny issues I've had on a 2021 PB? How about the crazy noise from one of the rear wheels? Also, depending on what the update/recommendation/quote is from this service visit and the issues I've mentioned I'm curious how bad does something have to be for the lemon law or for Ford to buy back a vehicle? Does a rebuilt tranny and potentially this rear wheel issue qualify? Don't know if I'm there yet but all of this is pretty disappointing having not reached 50k miles.

I had a noise similar to what you described and the dealership had to change the rear axle and something to do with the bolts being sheered of or idk. They also swapped out a front drivers side IWE module that is some part that electronically locks on/out the Axle for AWD. And then a year later the passenger side failed.
I’ve had other ford trucks without issues; my 2017 Raptor was purchased news and was trouble free.

not the 2021 PB
