So I've searched around and found that the push button starts had some issues. However we don't have a push button start.
Wife calls me one morning saying she got to work and cant shut the car off. After talking to her for a bit I drove to her work and gave her my car and drove the jeep to the stealership. Service guys and tech guys were baffled stating they never encountered or heard of this before.
Basically the car is in a zombie state. Brake lights are on 100% of the time, no turn signals work, no hazard lights, door locks don't work, pretty much nothing responds except radio and dash. Turn the key off and pull the key out, car stays running.
Dealer said they won't charge me for the diag fee as they didn't find any codes to indicate anything.
Fix action, disconnect battery and let it sit for a bit. It fixed it for a bit, but happened again the very next day.

Anyone seen this before?
Here's a video I upload real quick to show that I'm not crazy lol

 

I have never seen this before, nor did I even think this was possible. There must be some kind of either massive electrical or computer issue. I don't know if the hazards and turn signals have any connection to the vehicle computer, but if they do, then there must be a software fault in the computer. If the hazards and turn signals are not integrated into the computer, there is a wiring / electrical issue. For the ignition switch to not even function, there had to be something major, that should hopefully still be covered under the powertrain warranty, since it was manufactured in March 2015.

Make sure the dealer documents the issue as well. This one is beyond me.

I am never getting rid of my 92 Cherokee.

 

I dont know nearly enough to diagnose newer models, but the TIPM was the first thing to cross my mind as pretty much EVERYTHING runs thru that and can be a PITA when they go bad. Maybe it shorted somehow? Ive never heard of one causing what youre experiencing tho. Sticking relay? Faulty ignition switch? No clue. With newer vehicles, when the key is turned, there should be commands (ON, OFF, etc.) sent that the PCM picks up on so it knows what to do. It might take some time, but a dealer should be able to figure that out with thier high dollar scantools.

You more than likely need a dealer.

 

Dealer was the first place I took it to. Because they couldn't find any codes from the scan, they stated they don't know what the problem is.
Someone on another Jeep forum also stated that the crazy symptoms point to the TIPM also but those aren't cheap to just do a swap and pray.
So what should I do at this point? Dealer states they've never seen a car do this and can't find whats wrong. Really not safe to just ignore it. Do I call customer care (never heard of anyone getting anywhere with this)?

 

I was pretty much told powertrain warranty would be a mechanical coverage dealing with engine and transmission directly. Indirect electrical is not something they usually cover. Who knows....
Would they cover TIPM under powertrain warranty?

 

I do not know if they would cover the TIPM under the powertrain warranty, however I would push for the fact that what you are experiencing is not an "indirect electrical issue". An indirect issue would be more like a malfunctioning dome light, or power tailgate. Not being able to to turn the car off is a big issue.

I would also contact customer care directly. An incident such as this is so bizarre that it may point to a larger, future, systemic problem. It could require something as simple as a software update, or a larger problem that could end up with a massive recall. Imagine if many Cherokee owners begin to experience the same problem. If my Cherokee starts doing this, I'd be pretty ticked off.

 

Hi Baedarlboo, which dealership did you work with? Feel free to send us a private message so we can help get this resolved for you!

Like said, they (the dealer) should be able to hook it up to thier high dollar scantools and see if any commands are missing or incorrect that tell the PCM and whatever other modules are involved to shut down and turn the engine off. Something is keeping it from doing what its supposed to. I have seen this done on Youtube, so it is a thing. There were ON and OFF commands. IIRC, they were using a Snap On and Autel scantools (which i do not own, too $$$) Doesnt seem like the dealer wants to be bothered with this. No surprise to me really as most i have been to over the years have become parts changers. They dont like diagnostic work because it ties up the shop, for one. Which is understandable. I know what i speak of can be done, because ive seen videos doing so. SouthMainAuto in NY is one.

Good luck with this.

 

PM sent

 

Maybe I need to try a different dealership? Kind of lost at this point.
The issues happens at a minimum one a day, but more if I'm running errands make frequent stops. I don't know exactly when it happens, but I know that mid drive when my turn signals stop working that my brake lights are on all the time and next stop that car will not turn off. Have to carry a 10mm wrench with me to disconnect battery.

 

Have you contacted JeepCares yet (see post #7)? You should try them first, they might be able to assist before trying a different dealer.

I am curious if the JeepCares social media account is actually helpful. Given the oddness of your problem, the safety issue of no turn signals, and the potential for it to be a recall item; I would expect the dealer to want to hang onto the Jeep and escalate it to corporate.

From the description of break lights staying on and turn signals not working, it sounds like canbus issues or body computer crashing. Bad wiring in the dash maybe?

 

I sent a PM, but haven't heard anything back yet.

Dealer I took it to states they've never seen such a problem and could not pull any codes, so they sent me off with pull the battery cable if it happens again. It's happened 3 times today mid drive on the interstate and city roads. Only know it happens when my signals stop working....

 

They have been helpful on other forums, but they can’t force a dealer to get smart. It’s better to try than not to try....

Something else that I found is another safety concern...Driving in to work this morning and notice my turn signals stopped working again so I know what my next shut down procedure is going to be. However it started raining and of course, I had no wiper control. This is getting old and old real quick.
