It was only obvious if I was really paying attention. The only reason I actually began to notice it was I was driving behind an overland right after I bought mine and I kept noticing the lights on the tail would randomly flicker on and off and I thought, well that's weird. Then I starting watching my head lights do it, it was really strange.

Re: 2015 Jeep Grand Cherokee Headlights Flickering

Hi, i think what your experiencing is a brake down of one or more diodes?rectifiers in the alternator. This would cause the lights to flicker, you may notice your battery may fail over time to as a result of voltage surge over time cooking the battery. They don't flicker when the engine is not running as the alternator has no effect. The test done on the battery with the engine running showing 14.5 volts is a bit misleading has with these faults until it gets worse and the charging warning light comes on. different vehicle but same outcome, My Kawasaki zzr1100 has the regulator rectifier separate from the charging unit but was getting the same lights flickering, dash lights too. Turned out to be the rectifier breaking down, well known problem on some Honda motorcycles. Having your lights on protects your battery from overloading when the alternator is playing up. get it to an auto electrician and have them check the alternator out explaining what has been happening with your lights. hope you get it sorted. P.S. be careful to cover your alternator with a plastic bag if you jet wash your engine bay (obviously without the engine running) or hope to be lucky if you go in deep water.

yeah, thats what i thought. mine rarely does it but im pretty sure im not crazy and seeing things lol.. seems like it only does it if my radio is up with a lot of bass though, but it is very spontaneous as to when it flickers

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.
I just bought my first Jeep less than 48hrs ago. I purchased a 2015 Jeep Grand Cherokee Laredo Altitude. I noticed my headlights started to flicker on the interstate drive home. When I got home, I examined the headlights and found that moisture was getting into the headlight enclosure. It wasn't even raining out...
Shaakra, were you or the dealer able to find a solution? I have the tow package that provides the higher amp alternator. Does yours have the tow package also?
Has anyone else found a solution? This is my first new vehicle purchase of any brand and just a little disappointed. I've always purchased used previously.

Hi usamade, I apologize for the late reply due not being able to take my car back to the dealership. Yes, I do have the tow package which came with the jeep. Btw, I took my jeep in for an oil change this weekend and mentioned the flickering problem to the service department. They came back and told me that there was a body control module flash out there which should fix the flickering and he also said that if the flickering is still present then they would order a new steering column module? I'm not sure what the steering column module does or how it could prevent flickering? If anyone knows please feel free to chime in.

Re: 2015 Jeep Grand Cherokee Headlights Flickering

I'm a GM retiree and this is our first non GM auto. Just bought 2015 Grand Cherokee. First day we had it this head light flicker thing has happened. Has anyone ever have there headlights flicker, shutting off/on fixed yet? Been to the dealer a total of six days for this and of course they can't duplicate. Soon as we get it back it happens again. Got a case number going now and from there technical data base there hasn't been one other case reported in USA on this. So no one has taken there's to the dealer for this yet because there's no record of this problem? Any help would be appreciated.
I belong to a diesel site with over 400,000 members and there's some GM technical members that help us out. Is there any Jeep techs on here that are members to help us out?

I just went back and read an earlier post that said that the dealer found my issue and would fix it however I was wrong. They found a short that fixed another issue, they have never been able to replicate the headlight flickering and we actually joke about it now. Its annoying but this is a lease and I'm tired of bringing it back into the shop for an issue they can NEVER reproduce. I just figure in 2 years this is the next guys problem. Hopefully you get it sorted out. Over time its gotten a lot less frequent however I still notice it.

Hi. I've taken the jeep to the dealerships 4 times for this issue so I'm sure they should have that information from my car as a case. Have you received the new body control module flash? Also, does your jeep have a trailer tow hitch?

First time when I took it in they did the BCM flash. Said there was an update and didn't know if it would be the fix. They had it all of last week from Monday 7:00AM till Friday 12:PM Two different mechanics took it home every night and couldn't duplicate. I see they put on a total of 120 miles. Some mornings the lights will shut off Six times in my 8 mile trip to work. It's like a blink and I'm thinking they are missing it.
Yes, it has the trailer tow hitch package.
Was the new steering column module a fix for yours?

WARNING: To service any component of the SCCM, the entire assembly must be removed from the column. This must be done due to the clockspring passing through the assembly and into the self docking connector. Failure to remove the assembly could damage the pins of the clockspring and prevent the airbag system from operating properly.

The module located in the bottom of the Steering Column Control Module (SCCM), retained by three screws, and is the mating point for all the switches (remote radio switches, horn, speed control, steering angle sensor, tilt/telescopic switch, multi-function switch, clockspring) located in the SCCM. The SCM is screwed directly to the bottom of the multi-function switch. All the other switches are mounted on top of the multi-function switch.

No they haven't replaced the steering column module for me. The last thing that was performed on the Jeep was the BCM flash update.
