Brake Light problems of the 2015 Jeep Renegade

Got into Jeep to go home from work and I look down the screen is telling me my left signal, parking light and brake light is out. The next day it was working fine. A few days after that it did it again will I was driving this time the little light on the bottom right corner of the screen popped on and caught my attention,so I changed all the bulbs and still nothing so I check fuse it's good. Take to shop and find out the connector shorted out and the wires were corroded. This is a safety issue because had I not been paying attention and had my husband double check and make sure it wasn't working I may have never found this problem. The first time it happened was Tuesday September 3rd and the second time was Thursday September 5th.
