Begging for help!!!! '11 5.7 hemi with shudder/surge/choking. Is there a fix?
Hi this is the first time on this forum. I was hoping to get some help on my issue (which countless others have experienced by the looks of it). This is my issue:
I recently purchased a 2011 Jeep GC 5.7 V8 (w/51K miles). The truck drove great the first few weeks, but recently started experiencing the shudder/choking symptoms other owners have encountered. The issue occurs around 55mph or higher (w/acceleration or cruising). I tried using the Autostick (5th gear) and Tow/Haul tricks to disable MDS, but they didn't seem to work effectively.
I recently took it to the dealership to have looked at. They performed TSB 21-006-13. This only fixed another issue with the truck "clunking" at 40mph during deceleration. They also performed a tire balancing but that had no positive effect. I was curious about TSB 21-004-13, but was informed by a Jeep customer rep that this doesn't apply to my truck due to mine being an early release (built 11/10). He has opened a case and requested that I keep Jeep posted if the dealership doesn't find the issue.
I am here reaching out to ANYONE on the forum that may have a solution or even suggestion. Is there something that can be disabled or modified to stop this? I've read about the torque converter being an issue, possibly using a tuner/super chip (ex. Diablo)...this is all foreign to me, sadly. I love the jeep but this is ruining the experience.
