Electronic issues at highway speed - please help

2013 JKUR; 16,200 miles; stock except a SPOD and some accessories.

Driving on the highway in 2 wheel drive with cruise control on and the "sway bar" light kept coming on and kicking off the cruise control. Did not press the button.

Then more idiot lights flashing - "maintenance required; traction control; etc."; cruise keeps getting kicked off.

Now the cruise light is on but the cruise doesn't work. And the trac control light is lit up (can't turn on/off with button). No issues before today.

Any thoughts??? I'm going to disconnect the battery for a few minutes when I get a chance to see if that clears things up. Any other ideas on WTF might be happening???

Obviously it's an electrical issue. Any hep from afar will require more information on your SPOD including how you have it connected and what accessories you are running.

SPOD is wired right to the battery, I haven't touched any of the Jeep factory wiring. Nothing wired to the Spod has been on and no accessories were running while this happened.

I don't want to rule out the Spod yet but considering it's not connected to anything but the battery and was off when this happened I'm thinking it is something else.

Had to ask, you never know. Some known things that can cause your issues are :weak or dying battery, short, wet or damaged clockspring, or a bad TIPM.

Now the speedometer is dropping down and jumping back up<actual speed unchanged>. More idiot lights...ABS, brake, etc.

Thanks...I mentioned the spod just in case (never know) but I'm thinking something else. Weak bettery is interesting. I've seen several threads where people's batteries have crapped out after a year. I'd love for it to be something easy.

probably not the issue but if you ran to the negative post on the battery make sure it is not loose. I ran my winch to the negative post and learned that you can not use the main stud on the negative connection or it wont tighten up on the post.

I restarted it and the trac control light and cruise control light went off. I'm going to pull the battery terminals and let everything reset.

Check your ground to the vehicle after you make sure the connection is good at the battery.

Disconnecting the battery is a good idea. If that doesn't work and your battery is good, I'm betting that it's most likely the clockspring since everything you mentioned connects through it. You're still under warranty so take it in if it still is giving you a problem. Just make sure you rule out the "some accessories" if they're electronic.

Thanks. I have some lights and a backup camera. They had all been off during the drive. Restarting helped so I'm hoping disconnecting the battery clears it. I've never seen a vehicle lose its sh*# like this before. Really crazy.

I was going to mention this as well. A bad ground can raise havoc.

It could also be a bad wheel sensor or a short in the wheel sensor wiring. What you describe happened to me in my 2010. They said it was a bad wheel sensor, but then it happened again. They ended up finding a short in the wiring.

I'm betting a ground issue too. I just posted this - For all the wiper swiping, dash lights flashing, gauge bouncing issues....

I'm hoping that just explaining what I found will help shed light on another possibility for someone.

Thanks everyone for the input. I restarted the Jeep and the warning lights went away and it's been fine for a few days. I'm away from home for x-mas and the local dealer couldn't get me in before I have to head home so I'll have the dealer back at home look at it. When I talked to the service dept they said most likely wheel sensor but that's without looking at it, just based on the symptoms. After the dealer looks at it I'll post what they find (if anything...).

Have you seen an airbag light yet? So far, everything you said is ABS/wheel sensor related, but if you see an SRS light, then it would be the clockspring. Do you have any "accessories" under the jeep? Skids? Different wheels? Tires? Did you recently have any service done? Did you recently hit something that you thought was minor? Did you recently take it offroad? Your SPOD has nothing to do with this.

Haven't seen an airbag light yet. No accessories under the jeep and all my accessories are wired to spod (agree that's not the issue). No recent service...last was oil change about 4k miles ago and I rotated tires at same slime. Haven't been off-roading in a few months but I get out several times a year. Haven't hit anything. If it's wheel sensor do you think that's something I could see / would notice as being damaged if I got underneath the jeep?

Yes. Get underneath and check the wires that go towards the wheels/brakes...make sure they are well connected, don't look damaged, etc.

Definitely sounds like a main ground issue, check all body grounds. Highly doubt it's a loose connection for one thing (such as abs connection) to send that many lights off, and to be so on and off. Good luck man, keep us posted!

I had a similar problem. It turned out to be the negative battery connection. The clamp is just a poor design. I had to hold it closed with a pliers while i tightened the connector. Problem solved.

I had a bad ground (accidentally left the negative terminal loose after doing some work) and went for a drive...I didn't have ANY of the above symptoms other than the lightning bolt on the dash. Tightened up the terminal and all was well.

I had a similar (would happen at random times) Issue with my Cobalt. Reseated the connections on the Body Control Modul. Never had the problem since. But since it was intermitant it's hard to tell if that helped or not.

Is this intermitant? Or something you can show to the service department?

It's happened only during one drive (so far). After I restarted it's been fine for days. I'm afraid the dealer will drive for 3 miles and play the "can't replicate" card.

When I get home from holidays I'm going to put on jacks and take the wheels off to see I can see any damaged wires, etc. (I'm due to rotate anyway).

I looked at the battery terminals and everything is nice and tight.

I took all the wheels off and couldn't find any damaged or loose wheel sensor wires. Scheduled an appointment at the dealer this week, maybe they can find something when it's on a lift with better visibility...

So far has only happened twice and both on long trips so hopefully dealer can find something since they will probably only drive a few miles. I'll post whatever they find.

You said ABS in the vid, but its the traction control light that stayed on. I would take it to the dealer, show them the video, demand a loaner, and tell them not to call you until it's fixed and until they can tell you what happened. Problems like these you want documented.

Thanks for sharing. That looks a lot like what my Jeep did. Radio didn't crap out though. I'm really hoping dealership can fix.

So I took it to the dealer...I thought the bettery terminals were nice and tight but they said that was the issue. I still can't believe it but I was hoping for an easy fix so I'll take it for now.
