Got home put her in park and hit the stop button……. Nada. Still running. Had to disconnect the battery to shut it off. Starts and runs fine. Everything else works as should. Radio climate lights etc etc. just would t shut off. So the. I went to move it to a shaded spot to get out of the heat and up popped “service throttle control” and “ service stability control” and lost all gas pedal control. Truck is at dealer and they are struggling. Anyone have insight???

Not wise to disconnect battery of a running vehicle. That can cause a surge that blows things!
Pull something like the fuse for the injectors, fuel pump or ignition. but never pull the battery cable when a vehicle is running. You can blow electronics because it can cause a spike in voltage - alternators hate it. I've seen diodes blown to bits.

Hmmm ? ? Why I like a actual switch "key" start stop. Not that I have had a problem with my JT... but always been a thought. I've had circumstances in the past that the keyed switch has been a life or engine saver.

Bill,

Haven't we had a discussion "disagreement" about/ on this topic years back... of the push button start / stop ? ;)
I'm in agreement with you on not pulling battery cable to shut off. To many electronics that can be fried.
I think some of the vehicles I've seen involved in crashes have been totalled. Do to fire / rescue crew cutting battery cables and shorting out the electronics.

Not sure why people are lecturing the OP on disconnecting the battery.

I'm sure he understands it's not an ideal way to shut the truck off.

I'm not sure what the best alternative would be if the pushbutton doesn't work, as I'm thinking about it (for an auto at least).

Educating lurkers - and the OP - don't do it again there's far better ways. Forums are supposed to be places to get information - people search, they find a post like that and think gee, I can pull a battery cable to stop my engine.
It's an education, a warning.

.........for a stick or auto, pull a fuse. It's all over this forum where people have pulled a FUSE to shut things off. You want to kill ignition or fuel supply. There's a fuse to each. If anyone is concerned about having to find it fast or think fast, tie a red ribbon around it to make it really easy to find and pull out.
Not sure what the alternative would be? Think about what an engine needs to run, and check the list of fuses, or, read the other posts about this same issue where the driver pulled a fuse to kill the engine.
In the old days, you'd pull the coil wire. Pulling the fuse for ignition does this in a sense.

Actually, for a manual, I'd stall the engine first.

I don't disagree with pulling fuses or educating in general. No need to talk down to people either.

The problem is we don't know the why of this issue - yet. Is it the BUTTON? OR, is the PCM not responding to the signal? OR, is there a connection issue somewhere?

If you've ever had the starter stick engages and blow armature due to an ignition switch............. or had one fail to crank due to a switch...........
I've seen where a person could not shut off their engine and ended up having to pull the coil wire or the ignition primary lead, or put it in high and drop the clutch, etc. so it's not fool proof.
But - there are some advantages.

In the case like this, I'd want to know where the real issue was. Was it that switch, or something else.

As an auto-electrician over the years I've seen failures of even legacy electric systems in similar ways. A column mounted switch can wear or move out of adjustment you can't crank the engine, or can't shut it off. Contacts come apart inside and more.

I sort of wonder if we haven't hit near the peak of this trend because, ironically, the latest generation to enter the workforce is buying flip phones like crazy and dissing the technology in their cars. They apparently don't like it, according to things I've read just this week. And JD Powers says there's never been so much dislike of in-vehicle technology as there is now, and the complaints are at a high.
But millennials seem to like it. They like getting in, not touching a thing, pushing the pedal and going, then parking and getting out all without touching a single button.

No one's talking down to anyone - just warning them and anyone else looking.

No offense has been taken. And yes the fuel pump fuse was pulled to kill the engine but had to disconnect battery and leave disconnected till it was delivered to dealer.

Smart move. you could be sure of no chance of a electrical issue causing damage or fire.

Hoping they can add a stop button to uconnect. My daughter leaves the car running as she is in a rush at work at jumps out of her wrangler. Curious if the ESS function works still.

It hardly seems like lecturing when alternative methods are suggested..

My son has an Audi EV. He's been using my JT while they are up here from FL (they flew for obvious reasons - EV would have never made it)
Twice he pulled into a parking spot, opened the door and hopped out................ truck in D and engine running.
I laughed (knowing the truck wouldn't go anywhere and it was safe with autopark) but had to remind him - he's back in Iowa with gas powered vehicles and not all of them would just sit there like that.
