So, I had a warning light today that I have never seen before. After doing an oil change and topping off my coolant I went to start my 2012 JKU and got a crazy warning light on my dash. I got a repeating warning sound and the dash read "HOTOIL". I double checked to make sure I didn't drain the tranny fluid or something dumb like that but it was all normal. I had to disconnect my battery to get it to stop. I thought it was just a bug in the system but it happened again later on while I was waiting for some at a McDonalds window. Has anyone had this problem and if so what is the fix? My Jeep is my only mode of transportation so I need it back bad.
