2015 Jeep Grand Cherokee Headlights Flickering

Last night when I was driving on the interstate I noticed that my headlights were flickering. It was pretty dark on the interstate so I could really tell when the headlights would flicker. They would go dim for maybe half a second and then go back to normal. They didn't turn off entirely but only dimmed a little where I could tell that it was a flicker. I put them on high beams and low beams and they would flicker on both settings. None of the interior lights were flickering and the evic display was fine as well. I also watched the battery voltage display on the evic to see if it would show a drop in voltage when the headlights would flicker but the battery stayed on 14V constantly.
Has anyone else had this issue? What could be the reason for this? If anyone has any suggestions I would greatly appreciate it.
Thank you.

Could be a loose connector somewhere.

Where can I find the connection point? I apologize but I'm new with cars and don't have much hands on experience with them.

Re: 2015 Jeep Grand Cherokee Headlights Flickering

It's a shot in the dark but read my last post in a thread I started titled 15 Overland gremlins. It is where I found the cause of an electrical problem that I was having. It may or may not have something to do with your problem. Definitely worth taking a look at though.

So I did some more investigating into this and it turns out that the headlights seem to flicker ONLY when the engine is on and running. When the engine is off BUT only the headlights are on, they do not flicker at all. It's flickering only when the car is turned on and running and it could be at idle or while I'm cruising at 60mph and higher.
Does anyone have any idea what this could mean? Could it be a bad alternator?
P.S. I got the battery checked out at auto zone and it was fine. It was reading 12v before start up and 14.4 after start up.

Alternator handles the electricity when the engine is on. Electrical issues are a nightmare. Could the headlights be cutting out and what you see are the daytime running lights. I would be into the dealer and pretty mad.

Re: 2015 Jeep Grand Cherokee Headlights Flickering

My headlights are doing the same thing, I've tried turning the lights to auto then manual, does it both modes....

Dealer says they have not had any other issues related to this problem.

Video tape the flickering to document and show it to the dealer. It's under warranty, let the dealer deal with it. Might have to bring it to a few different dealerships as some are very incompetent and will tell you they can't reproduce the problem, that's why you need to video the problem. Good luck!

Re: 2015 Jeep Grand Cherokee Headlights Flickering

Did you ever come to a root cause? I am having the same issue, but the problem is I swapped out my headlights with an aftermarket set that include a LED strip. It would seem odd that new headlights would cause it as they are just a receiver for the bulbs.

I would hate to take off my bumper again to swap back to run more tests but I feel like the dealer would just blame my new headlights.

Re: 2015 Jeep Grand Cherokee Headlights Flickering

I know this thread is long gone but I had this problem as well. Headlights would flicker so I dropped it off this morning to replace something that cracked (evap related) and I mentioned the flicker. They just called me and said they found a short in the headlights somewhere and were tracing the wires back to figure it out. They would be replacing a lot of wiring they said so I wont have it for at least another day. Hopefully this fixes the issue.

Thank god for factory warranty's.
