so im dealing with this now. I have 4 ,19 rams for my bussiness and just bought one for personal use and the tailgate ajar light does not work. works on all the other trucks. so i take it in and the dealer says if it was built between april 15 19 and nov 22 19 then my truck doesnt have it. but its on the build list and has the option code. so from what ive figured out is something has happened at the factory and those trucks have had that option disabled at the factory.
what id like to know is an explanation as to why. and ram isnt giving it to me or the techs. i got a bs answer from the service manager to basically tell me to go pound salt. says it cant be fixed.
i say because ram doesnt want to replace faulty bcms to fix it, or what ever they need to replace.
if you are having this issue you shouldnt put up with it. its a standard option on all models except tradesman. its in the owners manual and the brochure.
im going to keep digging on this cause the service manager really pissed me off.
