Hi JR!Sho I trod the past few days to reproduce it with the start / stop enabled. No luck but as soon as I disable it fully heated up 2-3 min it throw the cel light and disables the start stop function. I have an appt next week with the dealer here in Florida. When I called my dealer in jersey they said they have not had anyone with that issues yet. Side not with the start/stop enabled the average gas mile in town is up to 21 and climbing. Guess that is a plus
Hi sho,I am back in the shop. Issue came back Sunday. However I didnāt have the cel only the stop/start error. They are looking at it now.
Most common causes for a P0507 code is either a vacuum leak or a faulty Idle Air Control Valve. There is a TSB for vacuum leak, have your dealer check it out,!I am back in the shop. Issue came back Sunday. However I didnāt have the cel only the stop/start error. They are looking at it now.
Sorry for the stupid question, but where do you find any thrown codes? Mine says no stored messages, just service start/stop. I've only had it throw twice since I picked up my Jeep the end of December. And it clears/resets when I turn it off. It goes to the dealer this morning for them to check out. Thanks.So it has been identified that there is a software issue with the 2019 jeeps 2L that is causing my issue. At this time FCA believes mine is the only one experiancing the issue but we all have the same software.
Proper identification is key to not wasting your time with a lot of useless parts replacement and time in the shop.
you need to watch the rpms after you see the error for start stop. when i am at idael and in park. At normal Ideal ~800 rpm the the computer is asking for more RPM's spacificly it wants 1450 but the jeeps is only going to 1150. once the pcm see's this mismatch is when the start/stop warning and CEL will come on.
This issues was identified preproduction in 2017 and a software fix was created for it that went into the 2018's. Apprently that software was not put into the 2019's. They currently are working on testing this code in the 2019 software and should be release shortly to all of us.
Until then if you experiance this issue my suggestion is get the dealer to report it. then clear all the codes. You can then drive your jeep with out issue if you don't sit in park for longer than 3 minutes the issue should not return.
I will let everyone know once I am contacted that they are ready to install the new software on my jeep. Hopefully less than 60 days.
I do want to say thank you to @JeepCares and the services manager at Royal Gate Jeep. Once they got involved to identify this issue they have been great to work with and have done everything they can to keep me informed and limit the impact to me as much as possible.
My issue is very easy to reproduce. if you have the same issue as me it will happen every time you are in park with the jeep at normal operating temps. Because of this the dealer has been able to connect to the jeep with his scanner and see it happen real time. Also mine posts a check engine light on the second or 3rd time the issue happens. That code is stored even after a engine shutoff.Sorry for the stupid question, but where do you find any thrown codes? Mine says no stored messages, just service start/stop. I've only had it throw twice since I picked up my Jeep the end of December. And it clears/resets when I turn it off. It goes to the dealer this morning for them to check out. Thanks.
