2014 electrical problems

Hey everybody,

I have a 2 door 2014 wrangler with 36,000 miles. For awhile now, when I'm driving long distances on the highway (more than an hour or so,) occasionally the traction control light warning light will pop on for a split second followed by a drop on the speedometer. This happened a few times before taking it in, and they were unable to reproduce the problem so they did nothing. It's still happening, and now when it does, additional lights come on such as the ABS and a few others. Again, it's just for a split second, but once it starts, it will happen every few minutes. Additionally, after this happens, if I park and turn off the jeep, it won't start back. I'll turn the ignition and get nothing... no sound, no lights on the dashboard, and also the remote lock will not work. I need to let it sit for 10 minutes or so before it will start up again. I took it back last week (before my 36k warranty was up) and again they could not reproduce the problem. They did check the battery, and everything was fine. I'm still having the problem, and am now over my warranty, and I hate to see what the cost is going to be to have it fixed. Assuming they can even find out what the problem is. Can anyone offer any suggestions?

Check your battery terminals and make sure they are good and tight first.

And are you noticing any bump on the rode prior to this? I have hit some good pot holes that have kick in my traction control

Ignore my post. Didn't read your entire post and it would let me edit mine. Could be a wheel speed sensor acting up. Have you been off roading? Check to make sure it's clean in hub.

As for the other symptoms those are all weird and unrelated to WSS hmm....

No, haven't done any off-roading. And the symptoms are sporadic which is going to make it hard for any one to reproduce the them. The "no start" problem just happened for the first time last week, but the sensors going off has been a problem for a couple months now.

Just came in searching for something like this. My 2014 sahara unlimited is doing the exact same thing as you described. Started a couple weeks ago, sporadic flash of the traction control light and a dip in the speedo.

Mines got 18k miles on it. It started before my lift/35s. Those were installed on Thursday and now it's acting up again.

Additional electrical info: I've added an spod and HID lights from hidprojectors.com along with a CB.

The last electrical item I've added is the $99 remote start that is well known on the forum.

None of those have shown any issues electrically.

Any problem getting it to start after experiencing those issues?

Mine has done it on the highway at speed and gone back to normal. It usually does it once and then a second time in a 45min trip.

But I have not had any starting troubles.

Since it seems to be picking up in frequency; this week I'm going to try turning off the traction control before driving and observe.

I had a similar problem, I also have an Spod and other things. It was a loose connection on one of the wires coming off the battery terminal.

I thought I'd update based on my experience so far. The odd behavior has continued at random times. On one trip home it went into full dash light disco mode with speedo/tach drops and just schizo behavior. It did this 4-5 times in one trip home from work.

So after reading up on loose grounds, bad ECMs, TICM and other expensive acronyms, I decided to try the negative wire first and see if anything improves. I was ready to drive to dealer after reading up on the recall stuff.

the nuts on my negative wire were tight, but the cable still had some play in it. Upon closer inspection I realized I have never seen a battery cable like this before. The mechanics of how it is supposed to tighten make no sense to me. I'll add a pic later explaining, but the design looks counter intuitive to achieving a tight grip on the post no matter what I did. Compare it to a traditional battery cable with the horizontal screw/nut for tightening and you'll understand me.

So I bought a small 3" C clamp and tightened around the post/wire terminal to test it for a while. It's been a week now with no occurrences of the lights/bells/whistles/panic attacks.

I'll keep the clamp on for a while since the freak outs have been so unpredictable. Until now I'd say it occurred maybe once a week; sometimes more, sometimes less.

The positive wire has the same fitting on it and I did notice less play in the wire than the negative. To me it looks like a terrible design on the wire fittings interaction with the battery posts.

That little conical seat nut that slides a hook-type thing to tighten? Yeah, that was a new one for me too. Weird.

That's it! Great site, hadn't seen that one yet.

My c clamp fix is still working. I guess I'll have to replace the battery terminals eventually.

Good link, I'm having the same problem as of last night. Started on the way to work, ran fine. Worked all night, got out this morning and Jeep wouldn't start. Jumped without issue... guess I'll be checking my connections later!
