My son has an intermittent flash of the lights on the dashboard
of his 2012 JK with 110,000 miles . I brought it to AUTOZONE but they say there are
no codes coming up. The fellow said bring the jeep back when they are flashing again,
but I told him its very intermittent and goes back to normal very quickly .
What should I do ??

 

Could be a loose battery terminal. Check that?

 

The negative terminal had the slightest (and I mean slightest ) play.
I tightened it up and after 50 miles...... no flashing lights.
Hope they stay off. THANKS !!!!!

 

yup, usually get a whole array of lights when terminals are loose, or as battery is dying.
