Stabilitrack error, check engine light, shift indicator not indicating which gear, backup camera not working, engine limp mode.

My truck suddenly gave me a stabilitrack error, check engine light, shift indicator stopped indicating which gear, backup camera stopped working, engine seems to be in limp mode. I had the transmission rebuilt 10,000km ago and they had difficulty with it. An O2 sensor went back. Truck has 155,000kms. Change spark plug #5? Not sure what this could be.
