Regenerative braking and winter driving.

[jeffreybt]

Hello all, I'm having some serious issue with my truck and winter driving and im wondering if anyone else is having the same issue with their powerboost and if they have found a solution.

My Truck: 2024 XLT power boost with Nokian Hakkapeliitta LT2 275/65 R20 winter tires and around 350lb of sandbags over the rear axel.

The issue is, on a slippery surface when there is a side force (From a slow round-about or a curve on the highway) if regenerative braking kicks in, the drag from the regen is enough to lock up the rear wheels in a turn. (basically acting like a jake brake) It's happened a few times around the city, but last night it happened on a bend in the highway and it almost got me killed (I was in 4x4 slippery mode).

I played around with all the modes and its worse in some more then others but I cant find a way to completely disable regenerative braking.

For now im going to put even more weight in the back and im going to take a huge hit and buy another set of winter tires with studs but id like another solution.

Thanks for any help.

Im coming from a Honda accord w/ the same tires (Nokian Hakka) and that thing was glued to the road compared to this truck.

WOW - I have a 24 PB and live is the cold and snow. So far I've not had that happen. I've driven a ton of roundabouts in slippery mode. I don't have anything in the bed of the truck though.

It's not so much snow, but packed snow or ice, I live in the rocky mountains and roads don't get cleared quick so a lot of the snow get packed down before the plows get to it.

I haven’t had this happen with my power boost. But any truck on snow pack/ice it’s gonna be damn sketchy when you hit the brakes.

As much as quite a few people complain about the factory, Perelli tires, I think they are solid.

What tires do you have?

This sounds highly unusual - I live at 6500 ft in Utah and drive snowy/ snow packed roads with my 23 PB all the time and have never had this happen. The initial regen when you come off the throttle is so mild there’s no way it should lock up the rear end- especially with the tires you have and the weight in the back. I only 3 peak rated AT tires and no weight in the back besides my bed cap. Have zero issues on corners unless I’m driving too fast for the roads. Maybe have your brakes checked?

Truck only has 3500 km on it but I guess I can schedule the mechanics to look at it.
I found another post with someone having the same issue back in 2021, and messaged him and hopefully he responds.

its fine when the service brakes come into play as they can engage ABS, its the in-between regen mode where it get sketchy

I have been through two winters with my F150, and I have not had that happen. It did happen a lot in my 2002 Dodge Dakota, which obviously didn't have any type of regen feature.

Slippery mode appears to disable Regen braking when I apply my brakes, if the ECO Coach screen on the gauge cluster is to be believed. I assume it is as it would make sense for the truck to allow the ABS system to do all the work in a slippery scenario. Any luck with that mode? Nevermind seems like you have tried it.

My truck doesn't seem to have this issue with all seasons and no weight on the rear. I wouldn't say my truck is glued to the road, but I've never experienced what you have. I also don't live in the Rockies, but I live in Ohio and primarily drive back country roads.

Hopefully you can find a solution because that's not a good situation to be in

There were a few people whom posted about this exact issue with their 2021s, etc. One of them included a video. Very dangerous.

I have not had any issues in the snow or ice. I don’t add any weight or anything in the back either the stock or my aftermarket tires. Doesn’t sound right, I would take it in for sure.

I have 24PB and thankfully have not experienced this issue. I hope you're able to get this addressed quickly.

Wow, that's alarming. I have a '22 XLT PB with Nokian Outpost AT's, and I've had every problem you can think of with this shit wager but I've never had my brakes locked up. I'm also surprised you need to have the extra weight on the back; I've never found I needed to do that in the winter time for traction when I'm in 4x4 slippery mode (I'm in Canada). This sounds like a job for a Ford certified mechanic who'll need to call someone else to help him.

24 pb platinum here also and have blizzak tires on it on smaller 18 inch rims. mostly driven in ny state and including in Adirondack mts. Havent noticed this issue and normally dont keep extra weight in the back. I do notice in the ev coach that it the regenerative brake zone seems much smaller in slippery drive mode.

 

[cheesedogf150]

22 PB here. If the roads have snow the trunk is in 4A or 4H mode and normal driving mode.

Never experienced that rear end lock up, also no bed ballast.

I just went and played on a side road close to the house. It is a gravel road that never gets plowed. It sees quite a bit of traffic so the snow gets compacted and it turns into a near sheet of ice.

My 24 PB did nothing of the sort with regenerative braking. I applied the brakes as I normally do at 40 mile an hour. In 4wd I had zero regenerative brake lock up or fishtailing. In 2wd I experienced nothing either. And I have no weight in the back, factory 20 inch Perelli tires.

I will state that yes, if I forcefully applied the brakes I did get ABS lock up like crazy. Nothing out of the ordinary, the standard ABS brake cycling you would expect on wet or icy roadway
