Thanks for the reply and info.It is my understanding that a TSB is only for when a customer comes in with a complaint. The only things a dealer are required to do is any recalls that come out from FCA. Because this is a Service Bulletin and not a recall, any model owned by the dealer will probably not have any TSB's done to it. You will need to tell them to take care of the issue after purchasing.
You can go to the mopar site and type in your VIN to see what notices are there.Looking to buy a new 2020 off the lot, what if any TSB's should it have done to it ?
