This loud clunking noise and vibration on downshifting has been going on for a long time. Happens when the vehicle is slowing down and the transmission is downshifting. A pronounced clunk two times as I slow down. I have taken the Jeep to the dealer and various repair facilities and it can't be fixed. The Jeep people claim they can't replicate the issue. I feel they are stonewalling me. I have spent a lot of money on this and it's unnerving especially when I have other people in the Jeep. "why don't you get it fixed they ask".
Service park assist system would come up and p r n d would light up, then Jeep would not accelerate until I put it in neutral or park and then back into drive. A couple of times when it would not accelerate it had completely stalled out for no reason. Check engine light comes on intermitently during this time. Also, manual shift bevel stopped working about 4 months after getting the vehicle (still covered by warranty) and was replaced, stopped working about 5 months after that and was replaced with the warranty but then stopped working again about 3 months later and is not covered by the warranty any longer. About 1 month ago heard a loud noise as I was going from reverse to drive and now everytime it shifts from first to second or second to first it shifts very hard.
