Promaster 3500 Forward Collision Warning turning itself off in Uconnect. Uconnect is where you can turn off FCW or set it to warning only, or warning and braking. I want it ON all the time but it keeps setting itself OFF. I turn on the vehicle and I see the warning light indicating it is turned OFF. I have to go into setting and set it manually. I will travel to get gas and when I re start the vehicle it is set OFF again. If I don't happen to notice it, I'm traveling down the road without this safety feature, which to me is dangerous and just not right. My Promaster is a Roadtrek van and the service manager at the dealer where I purchased the van says he sees this light on all the time on other Promaster vehicles and just ignores it. I see many posts on Roadtrek and Promaster forums that reference people having the same issue. Ram dealer finally acknowledged the issue but is unable to get any acknowledgement from the manufacturer that they are working on a fix. I've had this issue from day one and have taken it to the dealer several times with no resolution. This is one thread that documents what I have experienced as well: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
