Today I unplugged hood open sensor #2 on right side (driver's side) of engine bay. According to the wiring and software schematics its only job is auto stop/start disable with hood open. It gave me the the auto start/stop warning dash symbol, but that start/stop feature was driving me crazy. I drove the JL 68 miles today with zero issues (remote start works as well as backup camera).

Yes I am too forgetful to press the ESS button to off at every startup. This will hold me over until I can figure out a better defeat technique for this very undesired feature.

Why not after it kicks in on that first stop, just touch the botton, then it's off the the remainder of the trip?

I always forget until that first stop, also I am actually working on a defeat module that will be seamless and still allow use when wanted.

I'v been curious when someone will come up with a fix for this. I know on the F150's a simple jumper wire on the switch wiring takes care of it.

There is a permanent fix coming out soon from an established company.
I just didnt want to pay $100+ for $4 in parts.
My temp fix is fine with me, the auto start symbol is very unobtrusive on the display, I do not even notice it.
Plus it only takes 10 seconds.

Only downside to this is remote start will no longer work if you have it.

Why don't we kidnap Sergio and refuse to release him until FCA agrees to switch the default behaviour to remember last setting?

I tried this today. It did disable the start stop but also disabled the back up camera.

My back up camera works fine, unplugged for 700+ miles. No issues other than indicator on display that I never notice since it blends in with the other grapics. I know of 4 other JL's that have disconnected theirs with no issues.
Double check you camera settings on the uconnect.

I wonder if a receiver plug lite, which can defeat the ESS, will also defeat the Safety group detectors. If it does...I will go the 'disable the hood sensor' option.

Good point, i wouldn't be surprised if it did. I'd like to know that answer as well.

Let me do some investigating and I will have an update soon.
