Brought my 2011 Dodge Ram 1500 Hemi in for oil change last week and agreed to a couple of flash upgrades. Next morning the remote start would not work. Starts up runs for a second then disables. Turns out it only does this when cold. Also, I've noticed the average mpg is down about 4, doing the same kind of driving. Dealership wants it left overnight and can't with my business workload right now. Anyone else seen heard of this? Thanks
