  1. Towing with the Powerboost—very poor mpg

    Cobraman428 post 25. Thanks for your post. I have the 21 Limited PB truck and same travel trailer though the GeoPro model. 8 to 9 mpg on flat no wind 60 to 65 mph max. Will try out the 8-10 lockout for next trip. Should be a 900 mile two way Black Hills cross state trip so will have some...
  2. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    After a long hiatus from this forum I return to report: Our 2021 PB Limited still exhibits the dead pedal situation and we have NOT taken the truck to a dealer for the problem. We have had the active air dam and motors replaced since getting the truck. We are waiting for all the rich...
  3. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    Just an update from previous posts. Very little interstate and highway usage over the last several months, just 25 to 50 mile infrequent shopping visits to nearby towns. Vehicle had been performing fine, but this last week on startup neighborhood drives the old failure to accelerate following...
  4. What kind of MPG mileage are you getting with your Powerboost?

    Just got back from South Dakota to Kansas City 24.6 mpg (662 miles) including 4 days of short (8 miles per day) in city driving. Around 65 mph for the interstate driving, no hurry. Regular no ethanol fuel. Brand new spark plugs as truck is 66,896 total miles. In Kansas City I really...
  5. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    Thanks again to Financegirl23 for the transmission issue update. I would like to express appreciation for her leadership. Our vehicle is still irregularly doing the same thing. We would like it fixed. That being said, I am quite apprehensive of a transmission replacement by our local Ford...
  6. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    Ronicq, It was good to hear about the Ford Service Engineer visit. It's past time that I should have said Than You! I'm encouraged by your lead in this manner, you occupy a somewhat elevated position in this matter. Our acceleration failures are so unpredictable that I am certain a local...
  7. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    5-2-2024 Began 45 mile multi stop trip, cold engine. From home motored down hill two blocks, left turn for 3 blocks. Stopped at two way stop sign, mild acceleration to 15mph crossing intersection, where we found ourselves limited to 15 mph for a full 6 seconds with 3/4 acceleration application...
  8. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    Had not been on forum for awhile. The problem is still manifesting itself in town driving. The straight ahead acceleration failure has happened to us as well. I note the suggestion to turn off the traction stability as a test, have not done so. Ours has been irregular but often enough to be...
  9. Members with Michelin Defender LTX or LTX 2's on their trucks.

    Kanuck, yes... I thought that might be the course to take as well, thanks.
  10. Members with Michelin Defender LTX or LTX 2's on their trucks.

    Different sort of question- I bought our 2021 Powerboost with a new set of the Defender LTX 2 tires on it, October 2023 installed. The Ford dealership had no tire packet in the truck. The original owner was helpful, checked his files & found out his wife had thrown out their whole Powerboost...
  11. First trip of 2024 - FLA-GA-SC -- 10 day journey in 2021 F-150 Platinum PowerBoost towing E-Pro 20FBS Travel Trailer

    My combined cargo weight is 1308 lbs. I'm 70, wife is 68 so it is just the two of us, but we typically load up the back seat with full coolers with ice, groceries, my tool bags, & light luggage. We also installed the Anderson WDH. Two bicycles, the rack & kayaks at 80 lbs each. That was...
  12. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    Follow up report. Our vehicle has not been one that demonstrated driver "repeatability", there is nothing I can do to force the non acceleration issue. But Saturday March 23 during extensive in town driving with stop & go multiple turn less than 25mph traffic (run on sentence)... we had...
  13. First trip of 2024 - FLA-GA-SC -- 10 day journey in 2021 F-150 Platinum PowerBoost towing E-Pro 20FBS Travel Trailer

    Jerry, thanks for the post, especially relevant because we have our newly purchased 2021 Limited PB ready to hook up to our 2021 GeoPro FBS20. So we have identical rigs for the most part and seeing your weight ticket is most helpful. I do put a rack & two kayaks on top as well though. Our...
  14. Loss of acceleration. Mine is a2021 poweboost and it happens mostly in turns

    I have been experiencing this as well. Latest was two days ago, cold start with ICE running in engine warm up just above idle straight driving in town, Right hand 90 turn on to another street, pressed accelerator, vehicle response was zero increase in speed for full half block. Speed limit...
  15. Any good experiences from PowerBoost owners

    We just bought our Limited PB production date 11-2021 with 64500 miles. Drove down from South Dakota to Garnett KS, Victory Ford. Nice folks, really take good care of you. Previous owner maintained it well, looks like it came off the factory floor. He recounted only one service problem. The...
