2016 jeep CheroKee sport. . Ongoing problems for over one year. Taken it to two dealerships . FlicKering headlights and dashlights and domelights. First year battery want dead. New battery new alternator and now new power control Module . Just yesterday they cleaned all contacts on the grounds . Still not fixed . The dealerships cant figure it out . So now what ?

 

The explanation is a little above my pay grade, but Jeep has hit on a novel idea to get 0.00006 miles per gallon more out of your Jeep. All electrical usage is in pulses now coded with where it is supposed to be used. In effect, one constant source is divided up between several destinations, cutting down on the alternator output and saving a little horsepower. That power control module is supposed to divide up the power, which is why they replaced it. The problem is particularly bad with LED lights because they will go on and off instantly. Do you have LEDs?

 

Welcome to the forum.

Bump the problem up to the zone manager.

Keep giving the vehicle back to the dealership for repair.

Document the problems w/ video, if that will help the diagnosis.
