Thanks for the reply, I was this close to having a $1500 bill for no reason apparently. It sounds like they’re trying to take advantage of me with the situation, I would appreciate the link if you can but if not you still helped me way more than you know!Either you have a different problem or your dealer is feeding you some baloney. The shift to park issue, where you shift to park, the P lights up but it says shift to park on the DIC, is corrected with a 0.8 hour labor process where they clean the shifter and install a harness and switch. The harness is $15. The switch is $28. I have the part numbers and prices I can link if needed. They don't even list the shifter replacement in the bulletin anymore as the switch is what malfunctions. Even if they just put in a completely new shifter the part is $150 and it takes 1.7 labor to replace (published labor time, non-warranty).
They haven't made this one a safety recall because the car is in Park as far as the transmission is concerned. It is the BCM that isn't getting the signal because of that switch. An argument can certainly be made since the ECM is the receiver of the primary signal and the BCM acts as a backup. If the backup is toast, you are hanging by a thread metaphorically. But with zero accidents are barely any complaints at the NHTSA beyond cost, years have gone by and nothing.
