I want to help on this. I have the same issue. What do you recommend that I do here?So I'm just checking in on this thread as I haven't been on it in awhile b/c there haven't been any new developments on the regear issue. I have started a conversation with FCA/Stellantis on the limit they have built in to the brain on the 4xe's. Alexander with the Stellantis Customer Care team seems to be sympathetic to the issue. He has sent my correspondence to one of his (top) mangers and I'm hoping there's an easy fix and that it won't just be brushed off.
Since these Jeeps have the potential to be some of the most capable wheelers that have hit the highway with the lower CG and instant torque I think it would be crazy to hobble these with a stupid coding problem. I could see their sales numbers getting hit hard if the off-road guys turned their backs to the 4xe. I'm sure the R&D on these were extensive and not cheap. Hope they make it right soon.
