Despite the annoying seatbelt rattle (address by adjusting the passenger seat) and transmission getting stuck in 4th twice (repair and replacement resulting), I've LOVED my truck until I recently got a Hemi tuneup at 30k miles. Not as much that the dealer charged over $500 for the service but more that now mpg sucks and it seems underpowered (downshifts much more frequently and higher RPMs just to maintain 70mph). Feels like there's constant resistance almost like it did when towing a trailer (prior to this tuneup in tow mode).

Taking it back in but expect this to be the start of a long saga given initial explanations of "reflash of settings means truck is relearning my driving pattern". When new it didn't drive like this so this explanation doesn't make sense to me.
