2017 Sierra SLT

Great, that's what I was wanting to know. Other people's experiences. Thanks

I understand that, but I'm also noticing when I'm at cruising speed, the truck doesn't go into V4 mode like it used to unless I back off the pedal. Never had to do that in my 2015 or my 2017 before. It would usually go into V4 mode when I was just cruising without having to back off the pedal. I'm just asking if anyone else has noticed that as well?

After a few days of running the truck with the wood in place, I've noticed my gas mileage has decreased a bit. I believe the truck doesn't switch into V4 mode as easily as before. On a 65 mi trip last week I averaged 18.9 mpg. Made the same trip yesterday and had a 17.1 mpg avg. It had to be designed that way for a purpose and this may be it. Anyone else noticing a decrease in gas mileage?

I had my new Sierra at the dealer last week to have a leveling kit installed. Told him about the truck bogging down (which my 2015 didn't do) He told me to put some miles on it and it would work out. I came across this post, put a block of wood behind the plastic that's attached to the pedal assembly and the problem is fixed. BTW, I have adjustable pedals also, but the plastic piece that has the play in it doesn't move with the pedals. Thanks guys!!!
