So we do have a switch on the dash which simply disables the system but dose not solve the problem, I tried disconnecting the voltage sensor on the negative terminal but that did not change things, I found a thread on the web of a fellow that experienced the exact same symptoms and replaced the voltage sensor in the negative terminal and this resolved his issue so I think that is what I will do next, Amazon has some but the part number is different, it's lower than mine so probably mine us a later version on the 2019, unless it would interchange it looks exactly the same and is about 50 bucks, nine from the dealer is over 200!!
