So went to tire dealer agin today. They “updated” the tuner, went back to stock and then reinstalled the tire correction. Same thing no parking sense available comes up a d they turn off. Took it to the dealer and the found a code, cleared it and reprogram the park sense. Low and behold no more issues, they tried sending me on my way, I asked if they updated the truck with the tuner for the 35 tires as the Chrysler tuning won’t go that high. They gave me the run around saying it’s the tire dealer. I then lost my **** in them made them use the hyper tech tuner, and wouldn’t you know it park sense it broke again. So I got a loaner for the night as tired of eating gas and miles in the truck not to mention all damn evening. Needless to say they better fix it or they can swap trucks!!
Don’t think the tunes work in 2021 so be cautious if you plan on it. More to follow as it gets sorted one way or the other.
