I will agree with everything said here and would like to add something about the way we all drive and the auto start/stop feature.

This is the third vehicle I own with this feature, all of which are Chrysler/Jeep/FCA and have noticed something that I am trying to avoid/test out in my Rene.

When at a complete stop and the auto start/stop engages, when the light turns green, if I hit the throttle right away eventually I will experience a clunk/jump when the tranny kicks in and while shifting during movement.

However, if I just wait a second after the engine starts, nothing. It shifts perfectly.

So far, I have been good as I have been aware of this while driving and I have learned to control my really heavy foot a bit more.

I turn off the gas saving mode everytime I use the vehicle. The acceleration is worse with it on however turning it off does not improve the hesitation or the transmission issue.

This is an interesting note.

I am curious to see what happens with yours, having the auto start/stop turned off all the time.

Please keep us posted.

Do current manual-transmission Renegades have this?

I believe the current manual trannys do not have it.

I have to turn my stop-start off every time you get in the Jeep but thats not a problem because it aint worked in months.

Check your battery, the auto start/stop usually stops working when that tiny battery fails. I had this happen on my old Chrysler Pacifica minivan and one day. after months of it not working, the van wouldn't start at all. that battery is how the vehicle always starts.

Which tiny battery, where?

I was trying to find it, but I do not see it's actual location. I can say for sure that it has it though.

Why in the world would the auto stop/start circuit need a small battery?

It's how the system works, that's how they made it, I could say anything but I really have no clue. I can for sure say that it's there and that's what you need to find and test to see if it needs replacing.
