Purchased my 2017 GMC Sierra just a few weeks ago, saleslady didn't tell me anything about the truck going into V4 mode. After noticing power drops and almost getting hit waiting on it to switch out of the V4 mode, I had to read the manual. Educated myself and hated the V4 mode! Found this unit while browsing on the internet and purchased here at autoanything.com. This unit has allowed me to fall in love with my GMC Sierra. What a difference!
