Exclamation HELP!! All Indicator lights are on

A bit of info on my car 2012 C300 4matic 41k on it

This morning I started my car as usual but every single warning/ indicator light is on. The message reads malfunction / inoperative for every indicator possible. It starts up fine and seems to run fine. Does anyone have an idea what it could be? I tried searching the form but no luck. Will be taking it to the dealer later this afternoon.

If it has been giving you any problems starting at all recently, you might be ready for a new battery. Mine is a 2012 too and I needed one yesterday.

.

I thought of that as a possibility but I'm not having any issues starting. Hopefully it's something minor! It's at the dealer now just waiting for a call. Once they figure it out I will update everyone.

Unless you are out of warranty based on time, you can always take it in so they can scan it and tell you what might be causing those errors. It is always up to you if you want to fix it there.

So I got my car back today. Turns out I had a bad fuse box! Luckily it was covered under warranty. I'm not sure on the specifics because I had my wife return the loaner and pick up the car while I was at work. But I'm guessing a short if some kind.
