So I have an 07 JKU Rubi running Superchips Flashpaq 91 Tune with 93 Octane. So I'm driving through some hills around 50 mph with brights on and suddenly electrical loss!! Lights go out come back on and every light on instrument panel is glowing bright...all real quick and while I was cruising?? What the heck? So when the shock wore off I dimmed headlight back down and was fine no other symptoms, and has never happened before... Any insight?

 

I've had that happen before, I just chalked it up as an eletrical hiccup. Did you try to check for codes with your superchip?

 

Not yet, I'll do that at daybreak....thanks!

 

I'm sure others will pipe in but I think a lot of 07's had a problem like this. They called it the stall bug. Chrysler came out with a computer re flash to address the issue. CM

 

Could be a sign the alternator is starting to go. If you check the output voltage while parked it would probably read o.k. Hard to duplicate hills, rpms and high beams.
If your flashpak checks o.k., keep an eye on the alternator.

 

Thanks fellas, appreciate the input!

 

My "stall Bug" has been dormant for a while.

 

So once again I'm driving home today on 91 tune n abs light, slippery slider light and bas light illuminates and goes off n on???? Oh, and cruise control doesn't work???? What the heck?!! I guess I'll return to stock n see what happens!!
