Electronic parking brake sticking

So I noticed over the last few weeks that my miles per gallon was down from previous tanks of gas. Then I noticed that the vehicle was slowing going down some fairly substantial hills/grades. So I turned off the automatic electronic parking brake today and it appears to have solved the drag that I was experiencing. Obviously this isn't a permanent pic then I will get it repaired under warranty. I'm wondering if anyone else has experienced any issues with the automatic electronic parking brake?

Thanks

I’ve left mine on automatic if for no other reason that it actuates it regularly to keep it limber. I haven’t had any problems with it so far, though. I do feel like the truck slows down off-throttle more than I’m used to, but I’m also not entirely used to driving something with the Cd of a barn.
