I am about to drive for Christmas, and a light just came on in my car. All dealerships are obviously closed, and calling Jeep did nothing. I took a picture of the light that came on. Hoping anyone can help me, I don't want to drive my car if this could be something major.

Unless the check engine light is flashing, it's usually safe to drive. Stop by your local auto parts store and have them read it just to make sure.

Nothing is open, but Jeep was open- they actually called me back and did some diagnostics. They think it might be something with the sensors and humidity bc it's raining so bad here and I then parked my car in the garage. Fortunately, my father owns a construction company, so I'm going to take one of his trucks just to be safe.

PS does my first check engine light officially make me a Jeep owner?

Hope not as I have two 2013 JGCs and neither has ever had a CEL and my '97 wrangler only had a check engine light when the torque converter started to fail after 125,000 miles, but glad to hear dealership called you back and you have backup vehicle options

I've got a old reliable/ down and dirty Actron Pocketscanner that will read and erase codes, my Diablosport Tuner that can allow me to get myself into more trouble than I should and a wifi dongle that puts a wealth of information at my fingertips while driving using DashCommand.

But you're right most people see a CEL and blindly rely on a mechanic to tell them what's going on with their vehicle.

If it's a yellow CEL, you are probably ok. A red light means stop. Yellow means have it serviced soon. As long as it starts and runs ok, I would just get it taken care of when it's convenient. Plus you can get a transient fault in a sensor. Clear the fault and if it doesn't come back, forget about it. As others have said, get a cheap OBD scanner, make a note of the code, clear the code and see if it comes back right away or later or never.

Wasn't so bad when there were knowlegable mechanics around but seems more like what we have today is parts swappers.

Part of the issue is that most people capable of understanding modern cars have a clean, well paying, air conditioned job involving real computers.

This makes a group of hobbyists your best source for real answers. Odd thing is the same is true for computers. OTOH it certainly helps to be able to ask the right question.

ps will find a bunch of dongles at Amazon, I use a mini in my Crossfire because the room is restricted. The Torque Pro ($5) app on my smartphone handles the displays. Only thing to remember is to turn Torque off when not in your car.

pps when in my cars I use a Mountaintek CD mount to hold my phone and connect a charging cord while driving. My Galaxy phone can support BT to the dongle, Uconnect, and my smart watch at the same time. While running the sat-nav and playing music even. (only GC has Uconnect, other cars use a BT enabled radio to do the same. One phone, many cars.)

ppps: nothing cheap about Torque Pro and a good ELM compliant dongle (I like BAFX - plug), proper word is "inexpensive". For me the next step up would be the Autoenginuity system but cannot justfy the cost. Really is not much in the middle though for Windows I like Touchscan.
