I have a newer (10K miles) 2015 JK Unlimited Rubicon. Love it so far! My first Jeep in fact. I've been having a weird electrical issue, intermittently and totally random. When driving at speeds, more common when at highway speeds I get a cut in what seems my electronics. There is a "BEEP" then all my gauges drop to zero, the instrument cluster lights flash...sometimes its just the sway bar light but also the ABS and hill-decent lights and E-Brake lights flash. I even notice the radio skip as well. It only happens once right after the audible "BEEP". Same "BEEP" when you hit the gas reserve for example. But drives fine 99.9% of the time. No idea why it randomly cuts out. I can't replicate it because it sometimes happens every few minutes on the highway or it won't happen for few weeks. Any tips before I try the dealership. Its a hassle if they can't replicate it and find nothing wrong. For what its worth...I don't have any electrical modifications other than the winch up front wired directly to the battery. Thanks in advance for your help. Thinking something is messed up with my swaybar or something but IDK

Cheers, AV

 

I would check to make sure all battery connections are tight. Also, measure the voltage of the battery with vehicle not running.

 

I had the same issue on my 2013 JKUR. It seems to be caused by the cheap battery terminal connectors. I suggest removing them and retighten. This seemed to work for 20k miles till they loosened. At the end of the day I had to replace the connectors and have not had an issue since.

 

I had the same problem on my 2012. Bought a new battery and haven't seen it since. Was a good excuse for me to get a better battery

 

I'm guessing the connections are not tight as this happened to me as well. There is a conical bottom to the nut so if there is anything blocking it's path the connection won't be tight even if the nut is...
