I have a Ford case number. CAS-35379407-M1V9H. I was told that someone would contact me. I haven't heard from anyone. It's been at the dealer already and they did nothing to fix the shutter. Is Ford making any attempt to remedy this issue? Is it a software issue? There are many with the same problem and most were told to manually downshift on the highway to avoid. That seems a little ridiculous.

 

I am one of the people who have the shuddering (vibration) problem on the 2021 Powerboost. I am wondering if the gear ratio has anything to do with the problem. I have the 3.73 Electronic Locking Axle Ratio. This is probably because I have the max tow package. I am curious if the other folks who has the shudder problem has the 3.73 gears or if others who have the 3.73 gears does not have the shudder (vibration). Just looking for possible answers to the problem. Also when the shuddering starts I give it more gas and it really does not help much. This problem is really only isolated to hills. Thanks

 

Same issue around 50-60 up hill massive shudder, primarily is cruise control. Also have the abrupt 1-3 gear change mentioned above. Hope these issues can be resolved with software updates @Ford Motor Co.

 

I just took possession of a 2022 Powerboost Lariat on 30 Jan, ordered late Oct 2021, Dearborn-built early January. So far, I really like the ride and the engine, but maddened by the lack of any real time metrics on the charge of the hybrid battery. I have not experienced any vibrations at 55-60 mph, but I have heard some transmission rumbling at very low RPM (like 1000-1100 RPM) on the gas engine.

My quest now is to try to maximize “electric miles” on the driver MPG display - its possible to get the EV motor to take over at up to 45-50 MPH if you’re coasting on a flat or decline, but on an incline you’re lucky to go 20 MPH without the gas engine kicking in (as has been reported in earlier threads). The Power Distribution app under Features in the center display is very interesting, but I’ve seen at some times where the gas engine AND the EV motor appear to be powering the wheels - is that even possible, everything I read here in the past 10 months indicated NO.

I traded a 2019 Lariat 3.5L Ecoboost so I could get the 7.2 kW proPower option - I will say the 12” Sync4 center display is a VAST upgrade from the 8” Sync3 display I had in the 2019.

 

Of course it is.

How do you think it is that the 500-600 lbs heavier Powerboost is quicker than the EcoBoost, and that the Powerboost is rated for significantly higher horsepower and torque than the regular Eco? They work together.

My understanding is that the motor may be used in some situations to assist the engine to avoid using boost (or to use less boost) and of course, if you step on it, use both to get the most power possible.

 

I find this interesting, I had a 2018 f-150 crew and had a vibration also. Long story short after 2 months and changing all sorts of parts ford finally told the dealer it was normal. I traded it in a year later because it drove me nuts. I test drove my 2021 before purchasing.

 

I have a 2021 PB and have nothing like this right now. I have mechanical OCD so if I even had a hint of this, I would know. (I hope I don't get it because I have sold vehicles in the past because of unsolvable vibrations)

I also have 3.73 and a locking diff with the FX4.

I do wonder though...

Sometimes the when idling and the truck goes into a charge cycle, there are vibrations felt like a lumpy idle. Doesn't do it all the time and almost feels like a routine of some sort, maybe battery maintenance. I have felt it do this on occasion when moving but very rarely.

If you have a consistent vibration under power, I would first start at the pinion alignment and backlash then work to driveshaft. I had a Pathfinder with a power on vibration once that the dealer ignored. I pulled the rear driveshaft and ran in 4WD and the vibration was gone. This forced them to take a deeper dive and it turned out there was play in the pinion. They replaced the rear end and the problem was gone.

Again, I feel for you as if you are like me it would drive you mad.

 

If it’s helping, it’s not a whole lot - I observe maybe 200-300 less RPM on the gas engine tach when the Power Path display shows “Hybrid Driving” and the Electric object under the rear seat is blue instead of green. it would be nice if it was a bigger motor, but it remains to be seen how long Ford will even sell PB F-150s..

 

Hybrid driving is any driving when the Motor is on and providing force for forward motion, because the Electric motor is inline with the rest of the powertrain.

Your RPM's are not positively or negatively effected in any direction when the gas motor is running regardless of the Electric motor providing force. Also, any time you are accelerating the Electric motor is involved, it always is. How much force that is being provided by the gas motor is what varies.

 

Are you sure the electric motor is always providing force on the Powerboost?
