2016 2500hd denali gas peddle vibration

Hi so I have a new 2016 2500 denali with the lml. And it's great....but there's a weird vibration from the gas peddle. It's more obvious at a cruise (60km/h and 90km/h) and after a bit I can feel my foot going numb...so u don't think I'm imagining it..this isn't my first diesel (I've had a 2005 ford 6.0l for 10 years)...I just picked up the truck on wednesday and it's still on its first tank of fuel...has anyone else had this issue?

Thanks

Yup....I have felt this too in my 16 Silvy. It is annoying as can be, but mine is really only when it's going uphill, but I have felt it at other times as well.

I don't feel anything like that in my 2016 Denali. 1600 miles on it so far.

I have noticed anything in my '16 Denali. Only complaint is my peddle squeaks when pressed.. Annoying.

Is there anyway it's a power train issue or exhaust drone resonating into the fire wall...I can feel the brake peddle vibrating as well

Thanks

To the guys that have the vibrating pedals. Do you have the pedals adjusted all the way forward (toward the firewall)? If so, adjust the pedals back a little bit and see if it changes the vibration. Just thinking out loud here

Yes I've tried adjusting the peddles up down...it does see to get worse as you move them closer to the floor....the vibration persists even when the peddles are raised....don't mean to complain...bUT it's annoying....I read that some people are experiencing issues with the heater hoses vibrating on the firewall...but that seemed to create more of a noise than I vibration...at least from the posts I read..

Thanks thou. .I wish adjusting the peddles would fix it...

Did the Dealer happen to say if this was a 2016 issue only?
