hello everyone just thought id throw this out there and see if anyone has experenced this. it started yesterday after work outside temp is -20 truck was plugged in, started it up and warmed up like normal approx 5-7 min then when i starated out for home i could feel a vibration coming through the gas pedal and floor its almost like a hum without the noise. anyway it went away once it was up to operating temp.
today its -22 and did the same thing but this time it didn't go away it seems to be from 1000-2000 whens its cold and about 1700 once its warm.
anyone else experence this i have a 2012 crew 4x4 with a hemi and 3.92 rear

 

I have same truck and I get intermittent gas pedal vibration while driving. It's annoying but the dealer won't acknowledge a problem. Doesn't make sense to me because it's drive-by-wire, unless something is rubbing against the wire or firewall (I can't feel it on floor, brake pedal, anywhere else, only through gas pedal).

 

mine does it only when its very cold now that its warmed ûp i dont feel it anymore if it did it all the time i would be upset. what does the dealer say "cant feel it"?

 

Exactly.

 

id take it to a different dealer thats bs

 

It is a torsional vibration coming from the HEMI engine at certain rpm`s, some have it bad, some dont. Learn to live with it, its not going to go away. If you cant live with it, buy a different brand of vehicle. This is what happens when you start lightening up vehicles chassis`s and body`s, nothing ther to absorb anything anymore.

The only fix is bolting a bunch of large "vibration absorbing ballasts" to the engine block in various places, this is the only way to soak up the torsional vib`s before it gets transmitted to the chassis and cab. I have built a few ballast`s for my own hemi truck and it solved the problem entirely.

 

I just live with it, and mine is brand new. I think we have gotten so picky about cars today. My chevy had its quirks too. I just accepted it.

 

i live with mine also but it still doesnt make it right. As least its only in the cold

 

wasn't there a pedal recall for vibration while breaking or at certain speeds??? i could have swore i read something about that a while back on another forum

 

Yup, another forum alright, just not the dodge forums....lol
Maybe you were on the boyota truck forums....lol
