My 2011 Overland 5.7 has feeling of misfire/shudder whenever accelerating up slight inclines or even into headwinds, and I think it is disgraceful especially since it did not do this when new. This is not just a single event when going up inclines, it will surge/misfire/shudder all the way up unless I force downshift to overun it. Have had it to dealer and been in touch with customer service MANY TIMES, and they basically say "too bad". If I wouldn't be taking such a bath on it, it would be gone. Worst part is, I purchased this vehicle after SEVERAL test drives and love the looks, comfort, features and power of it. For those to just accept this, I find that unbelievable. Without consumer pressure, they will never fix this issue. This IMO, has nothing to do with off road capabilities making this vehicle "tough" so that we have to put up with trans/torque convertor ISSUES and/or fuel system calibration issues. I would gladly lose a bit of mileage if they needed to fatten up mixture a bit in portions of their mapping, in order to get this 5.7 to run smoothly. I also agree that Chrysler very misleading to all since it seems these issue to not come to light till a 1,000 or 2,000 on them. Sorry bout the rant but I find this issue a slap to our faces as we could have bought a dam 10,000 %^%#%*& import that runs perfectly.
Also have the feeling of something "slipping then engaging" when taking off from a stop at times but have just accepted this one as run issue P's me off a 100 times worse.
