Maybe I'm referring to something different, but the device plugs into the OBDII port. I have to remove it when I take for service because they plug the diagnostic module into it.
If your device plugs into the OBDII port, then it "may not" function anymore with the MY18 vehicle, depending on what it does, etc.

Hopefully it's just drawing power. I don't think it taps into the electronics of the car. Then again, as you can see, I'm pretty far out of my depth on this one.

To be clear:

Since you’re getting a Summit I believe the stop/start module plugs in under seat and you can still use your OBD II port for your hotspot.

Well.....if you’re getting a Summit (or NOT getting a Laredo, Altitude, or Upland) then we kinda know now. ;-)
I think we're talking about two different things...I was concerned the firewall mentioned might prevent the wifi module from working properly. I don't have the aftermarket start/stop module (yet).

I probably should have started a new thread instead of rudely piggybacking and introducing a new topic. Anyway the wifi/hotspot module works well. Thanks.

Question on using this for Sport Mode memory on my 2018--

I am noticing that sometimes when getting in the vehicle, sport mode will indeed be active, however, Quadra-lift will behave as if the vehicle is not in sport (Normal Ride Height until 52mph then Aero instead of the default of being in Aero when in sport mode). Is this expected behavior?

My start/stop had pretty much stopped working. Status almost always said "battery charging." I had them look at it on my service call this week and they replaced the aux battery under warranty.

Sounds like you stumbled on a good way to permanently disable it. Simply install a switch in the battery cable to disconnect the auxiliary battery from the system. Then, every once and a while, you can reconnect it, (via the switch on a long highway trip), to maintain the charge. When the switch is in the "OFF" position, the car will think the battery is dead, and automatically deactivate the stop / start system.

Any on line "vehicle report" will show what yours did. You could locate the switch in some area away from the battery itself, where no one would be the wiser. Then when you take your vehicle in for service, just be sure the switch is "ON", and the system is working normally. They won't try to fix what isn't broken.

I actually like stop/start. But my wife hates it. She picked it up for me at the shop, and her only remark was "You will notice I turned off that stop/start thing. It makes me nervous."

That seems like a lot of hassle to accomplish the same thing as simply purchasing a $150 plug-in module.

Or simply press the button that's just a few inches away from the gear selector when you have to take it out of Park after you start it.

Yes, but I’m referring to a simple way to disable it. I use the SmartStopStart module and I love not having to remember the button.

Bingo. The GC is not my only vehicle so I kept forgetting to push the button. Plus it's annoying to have to remember to do that every time you start the vehicle. So after a few times having the vehicle stall out at stop signs and then remembering that I'm driving my Big Brother vehicle, I bought the Smart Stop/Start. Works great and now I have a normal vehicle like my other's. I will avoid buying another vehicle with Stop/Start in the future. I realized how insane it is to pay for a system I don't want then pay for a device to disable the system I just paid for.

Well less than a week after the dealer replacing the aux battery, my start stop is already back to not working, "Stop Start Not Ready - Battery Charging." So I guess it's something wrong with the charging system, not the battery. Oh well, I'll have them take another run at it on the next visit in another six months.

Hi BubbaATL,
We're sorry to hear that this wasn't resolved for you the first time around. Please send us a private message once you are able to return to your dealer for further inspection and we'll gladly assist with that process.

Guys, the Start/Stop button is just a quick press of a button that you can reach without even having to remove your hand from the gear selector. You have to press a button to start the vehicle, press one more to disable the Start/Stop feature if it bothers you.

I personally can live with or without it. I usually disable it when shifting out of park but sometimes I leave it on for whatever reason. I tend to turn it off if I'm going to be stuck in stop and go traffic but otherwise it doesn't bother me if it remains on during my trip.

My father-in-law's Subaru also has the start/stop feature. But once the button is pressed to disable it, it says off until you press it again to enable it. Come on Jeep.

Not likely to happen because it then affects CAFE qualifications and how the fleet mileage average is calculated if the SS system doesn't revert to "on" on restart. And AFAIK, Subaru's current SS system also defaults back to "on"...it's a bone of contention in the Subaru oriented forums that I participate in, too.
