3.5L vs V8

[Greeco]

Just go drive a V8 version of your truck at the dealer and see how it matched up. Maybe it's not a 3.5 problem. Don't just assume it is.

Yeah, that’s a good idea.

Taken it to 2 different dealerships…both claim it’s “normal”.

I’ve read a ton of forum posts regarding the vibration in the gas pedal in these trucks. Some have it, some don’t. It’s annoying.

Ask them to do a cylinder power balance diagnostic test, Also known as an engine power distribution test. When they find the misfire just leave it there as long as possible. After 30 days you may qualify for a buy back with your year and mileage. Good luck

I have a new 2025 with the 5.0. I have the same vibration and only have 1600 miles on the truck so far. I have taken it in 4 times in 45 days. It's still in the shop. Had the dealer Road Force balance the tires. Two out of four were so far out of spec that they are going to have to replacing the tires. Both tires are on the rear. They were badly cupped on the inside edge. The southeast manager is coming in today to look at the truck. My guess is that there could only be a few things could be wrong. Bent axel tubes or axel shafts. The rear solid axel really doesn't allow for much adjustment, so we shall see.

Anyone else regret going with the 3.5 over the coyote? I’ve put 13k miles on my 2023 Eco and the truck just feels off. The vibration in the gas pedal drives me crazy. In 4A when the front wheels are powered the vibration gets worse. Almost a grinding feeling. The turbo lag seems excessive at times.

This is my first Ford and I like the truck enough to keep it but I definitely should have done more research before going with the 3.5. Definitely first world problems…..

I have a 2022 with 70000 km on it, I don’t have any thing like that. It’s instant torque when I step on it. The only issue I have is it’s been so cold in Southern Ontario the truck takes a long time to warm up and drive normal.

Very Interesting !

I had the same issue with my 3.5. Tires were out of balance. Had them re-balanced at a tire shop (not Ford), and never had the issue again.

Because I have a tendency to put a lot of miles on my vehicles I went the the 5.0. I have been frustrated with problems with turbochargers in my BMW's so I will buy naturally aspirated whenever possible. I was looking at the Tundra until I found they dropped the V8 option. Very happy with my choice.

I’m assuming with the tires out of balance the vibration occurred in 2H and 4A? My vibration is only when power is delivered to the front wheels and at higher RPM’s.

I have experienced that gas pedal vibration when looking for trucks before I found my Tremor. I test drove one with that issue and it was the most bizarre feeling I can imagine - feels like your foot is falling asleep. I got the same story from the dealer "it's normal" - the hell it is! Some good advice on this thread, but if it's what I experienced, the single most important piece of advice is not to live with it and that it's absolutely not "normal". My 3.5 (2022, 67K miles) is smooth as butter and DEFINITELY doesn't have anything like that going on.

FWIW, when I dealt with the dealer on the truck that had it, I got the distinct impression that they DID know what it was and were trying to play dumb.

My foot falling asleep is a great way to describe the vibration. I’ve narrowed it down to when I aggressively get on the gas in 4A or if the truck is in Sport Mode. In Sport mode the vibration starts around 2500 RPM and continues until the RPM’s drop. I have a V8 Tahoe and can rev that thing up to 5,000 RPM and not feel a thing.

The dealerships in my area are ridiculous. They want to keep the truck for a week just to diagnose the issue…..in other words, the truck will sit on the lot and they’ll get to it whenever they feel like it. Meanwhile, they don’t offer any type of loaner vehicle.

I agree with you, I’m sure they know what’s going on but don’t really want to deal with the hassle.

While it may be happening to aggressive acceleration and/or 4A, I suspect that the issue is broader, just less noticeable. The truck I drove had it going on even under normal driving. If the symptom is the same, the cause is likely the same, just different degrees.

That's ridiculous! I would recommend getting a new service advisor who can tell you a date to have your vehicle in so it won't just sit while you don't have a loaner. If they won't play ball with that, contact Ford and get a case started with them.

To be clear, the vibration is high frequency. It’s not excessive. In 2H I don’t notice it much. In 4A I notice it during acceleration at higher RPM’s. The feeling in the pedal is distinct enough to tell me the front wheels are getting power. Again, it’s not necessarily excessive vibration but it doesn’t feel normal. I’ve driven plenty of 4-wheel-drive vehicles that don’t do this.

I’ll address it again at my next oil change but I’ve already been told twice that it “normal”.

I had IWE issues on our '24 V8, and it felt just like you are describing. I would have your dealer check the IWE's.
It was intermittent, both in 2wd and Awd.

That’s all that matters, that you like the set up !!

5.0 here. Same issue. Getting fixed on the 17th. It's annoying and makes you question going 'out there' around where I live until it's fixed. Getting stuck on National Forrest roads this time of the year is an adventure... an adventure you don't want to have.

But like others... love the sound of my Coyote. Had a bunch of eco's in my Raptors and I'm done with them. That's just like my opinion, man...
