Break Down - Service Electronic Throttle Control and Stability Control

[JeepCares]

It just happened with my 2023 yesterday with 9K miles. Turned it off and when pressing the ignition switch to try to restart/reset it a few times it would rev super high. I then cycled it several times and now it is fine, but I was planning on doing a summer road trip but have lost confidence it to be safe. Wlll see if any fuses are loose this morning. Any more info on this? Now it sucks having a car you cant trust

Hello, aparently because of a loose ground wire all this lights came on. ESS doesn´t work (both batteries where changed recently). I haven´t notice anything wrong with my jeep regarding power of arnything else. This lights have been ON for about 5 month now. Any ideas of what can it be?

Also I am looking to clear all this lights, (I am an android user) what OBD2 system you recommend me just to read/clear codes? Will it work to clear all this lights?

THANKS!!

Not regarding the warning light for the electronic throttle...but make sure not to run so low on fuel or you might have the C4 high pressure fuel pump explode too, good luck!

I just had this happen to me shortly after filling the tank on my 2020 Ecodiesel. Limp mode with Service Electronic Stability Control and Service Electronic Throttle Control. First lights I've ever had. I thought I was one of the lucky ones. Hopefully this isn't the start of a long issue.

Update: issue is resolved. It ended up being a dirty fuel filter causing low fuel pressure. Changed it out. Reset the codes and it’s been good ever since. It’s also running better than ever. I can’t believe how dirty it was for only having 30k miles on it. :

Did you get yours fixed? My 2018 has the Service ECT and ESS warnings/limp mode and is in the dealer shop getting the parts cannon shot at it. They don't know the issue yet.

It turned out to be rodents that ate into the wiring harness, which is a relief at least its not a chronic problem
