Recently, my 2012 JKU started having strange issue with dash lights. Basically, while driving down the highway around 65 I was hearing the jeep warning ding, but couldn't figure out where. Finally, I caught multiple lights (ABS, Traction Control, and Brake warning lights) lights come on at the same time. Additionally the speedometer would drop to 0 and come right back to 65 mph. I caught it happening on video too.

Anyone experience this on a 2012??

 

Here is a pic I grabbed from video. Keep in mind I am still driving at 65mph. Look at speedometer

 

Mine was doing the same thing. About as quickly as it started it has since stopped and never came back. I had read previous threads that said it might be a wheel speed sensor. But never changed mine.

 

If warning lights are coming on, then there would be codes set in the ABS system.

 

Do you mean that it would be captured in CPU?

 

Sound logical. Mine has been doing this on and off now for 2 weeks. It also appears to be getting progressively worse.

 

Found this which seems to make sense: http://www.jkowners.com/forum/showthread.php?t=56570

Now I got to figure which one, I hope

 

Yes a code would be stored in the ECU. That would give you an area to check.

 

I just found this thread because I was about to post something similar...

Mine is doing the same thing (hill decent, ABS, traction control, and parking brake) with the lights and the ding, and the speedo drop.

It happens to me going straight, around left curves or right curves, going slow or fast - it's very random.

It just started a day after I installed Currie Antirock sway bar system on the front, so I assumed it was something with that? When I had my stock sway bar and JKS links on this didn't happen.

 

I had the same problem with the idiot lights. For me...My negative battery wire was loose!. I tightened it and it was still loose! Went to Auto Zone and they had the perfect fix. Small lead cups, (?) that go over the battery post. I could not get the entire cup on the battery post because I couldn't open the battery terminal up enough. Not to worry. I cut the cup in half, forced the terminal back on the post and...Tight as a drum head and NO MORE LIGHTS!!!
