Squeak/Chirp going in to electric mode

[ryanc111]

Here’s a weird one for you guys . . . I’ve recently noticed a squeak or chirp from my Powerboost periodically. It’s fairly muted but I can hear it with the windows up. It doesn’t sound like something is rubbing or grinding, it’s only one chirp and frankly I’m not overly bothered by it. More just curious. The sound seems to be coming from the left and behind the driver - at first I thought it was suspension related - perhaps the springs on my RAS springs on the rear.

After paying attention to it further I realized it wasn’t suspension as it didn’t happen when I was doing anything that was stressing that (i.e. braking, turning, bumps, etc). I believe I’ve narrowed it down to only happening when the truck switches to electric driving. At least that was the correlation when I started driving home from work today but about 15 minutes in to the drive it stopped making the sound at any time.

I’ll continue to monitor to verify the correlation and see if I can establish more of a pattern (just until something warms up? truly intermittent? something else?) but thought I would post here to see if anyone else has seen something similar. . .

Hi there! Would you send us a private message with your VIN and dealership name and location? I’d like to look into this concern on my end.

I have this same issue. Noise happens when the engine shuts off transitioning into electric mode. I Can’t figure out where it’s coming from.

Hi there! Can you send us a PM with your VIN and Ford dealership information? I’d be happy to look into this F-150 concern on my end.

Me too ?‍Get the “squeak” when going between electric and power while driving.

My truck was at the shop for almost three weeks. Service department determined it’s a bad actuator. They ordered a replacement part ML3Z*5A212*W. Unfortunately the part is on backorder with no projected ETA. I was able to pick up on truck last week and can continue to use it until the part arrives.

Thanks for the feedback here on a potential cause (and the fact that I'm not the only one having this issue). Shortly after I posted this I started noticing an issue with the transmission where I would be stopped at a light, in drive, and it would lurch like a clutch was slipping.

The dealer determined it was a bad transmission pump and after three weeks of waiting for the back ordered part (luckily with a loaner truck) the lurch has gone away. However, the tech claimed that the new pump resolved the chirp but not sure what he was testing because it happened on the drive home from picking it up and still happens consistently. Ugh.

Who knows? Perhaps they'll have the trailer brake recall finally figured out by the time they get this resolved?

You’re a rockstar @Jedala010! My truck was back at the dealer for the past week working on this issue and they weren’t making any progress. When I shared the information you posted they confirmed that this is indeed the issue. Now we just need to wait for the part to get off back order and arrive. At least I can drive it in the interim.

Probably the first time ever of a dealer service dept taking ”something I saw on the internet” seriously.

Thanks again!

Yes let’s hope the part arrives soon and it is the fix.

FORD Please help as i am having a similar issue. a loud squeaking sound coming from the electric part of the drivetrain. it is not the normal electric sound and you can hear it with the engine on too when the electric motor engages. Maybe i have the same bad Actuator that other members have had? #ML3Z*5A212*W

I'm supposed to get mine installed on Monday - I'll let you know if it fixes it for me.

Well, picked up the truck and . . . so far, so good. I've only put ten or so miles on it coming back from the dealer but the sound is gone and it is super quiet switching from electric to ICE.

Assuming this holds I'm considering it solved. ?

I recently noticed the same issue on my 22 Powerboost. It only occurs at cold start for the first fifteen-twenty min and the noise goes away after highway speeds. Did this ML3Z*5A212*W resolve this issue? I haven’t had a chance to bring it to a local dealer yet. I purchased the truck quite far from where I live.

Ryan,



Did those 2 repairs do the job? Cause i stated getting the squeek and the lurch, at 29k miles on my 2021 powerboost. The squeek about the first 5 minutes of any drive that it switches to electric only,And the lurch, usually after 20+ minutes of driving when I come to a stop. Scared the crap out of me the first time it happened, bumper to bumper in a drive thru and my truck jumped forward for no reason (my foot was on the brake) and made a loud clunk.

Yep, things have been great ever since.
