2015 X weird vibration at certain speeds and rpms

[Virgil miranda]

I have a EcoBoost 2015 X limited with 45k on it . Started making a weird vibration can feel it on floor were feet go and through steering wheel u can even hear it when it happens the digital tachometer shakes when it happens. It doesn't do it all time thought it could be bearing or suspension but what ever it is the digital tachometer shakes when the vibration happens. Does it between 1500 and 2000rpm at different speeds mainly high but on city streets as well only does it when ur foot is on gas . I will try get video

Sounds like torque converter issues? If you can replicate it, do it for the dealer and let them figure it out you're still under the powertrain warranty.

 

[Virgil miranda]

They have a way to tell if its transmission or converter

It just may be a misfire on a cylinder. Have you checked or changed plugs?

 

[Virgil miranda]

No I haven't wouldn't I get a code

 

[Boostedbus]

No I haven't wouldn't I get a code

Not necessarily right away especially if it’s intermittent. It seems to me if it affects the tachometer then it’s more likely in the ignition system

 

[Virgil miranda]

If no check engine light what is best way figure out what coil or plug it could be

 

[coolzzy]

Replace all 6 plugs for $30, you're certainly at the mileage where it could be beneficial, especially if you tow with the truck. Ecoboost is hard on spark plugs....

 

[Boostedbus]

Yes I would change all plugs and inspect each one .... if one looks more fouled than the rest then it could just be the plug giving up or that coil pack starting to go. But take note what cylinder it is because if the plugs don’t cure it then you’ll have a starting point for checking coils. Reading plugs can tell a story on an engines performance.

I took it ford dealership they hooked there machines on it said no misfires or anything with tranny they recommend a flush so I did granny flush and transfercase so I did that with them seems better but going take it on longer ride . If there machine showed no misfire could it still be plugs but if it is better after flush probably not plugs

The best way I’ve found to find a misfire is power brake the engine. Make sure of course E brake is set then power brake to simulate load/stain on engine. That’s when a weak ignition system will misfire most. If it does start misfiring then shut it off and find the fouled plug.

Is this fairly slow speed? Maybe feel it while travelling over a speed bump? Kind of feels like the antilock brakes rapid pulsing? I had issues similar to my description and it was an IPC sensor at the left front wheel. Took a long time for the Ford Mechanics to figure out.

Hi I had the same exact problem brought it to the dealer 2X before they found it. I was a front wheel bearing that was starting to go. They replaced it under warranty

My 2016 is in the shop for this issue right now. It behaves exactly as the OP describes when driving normally, but when I have a boat attached it's much worse. The dealership has a case open with Ford. Updates to follow.
