So I have owned a Ram since they first came out, so this one is new to me. Never had this happen on my '16 either. Anyway, when I go out in the morning it is like the brake is all pumped up. It is rock hard and I can't get the start button to do anything, until I can get the pedal to go down far enough. Like I said I never had this issue with my 2016 Sport. Anyone else notice this? This last time the truck sat for two days. This is my new Copper Sport edition with a tow package. ?????
Other than the trans shifting a lot at low speed this has been my only issue......so far.

 

Vacuum leak in the brake booster? The residual vacuum from when you last parked it should allow the pedal to depress one time with little effort the next morning.
