For some reason, my abs, bas esp, and traction control lights come on randomly. This past weekend, we took a trip from Ohio down to Tennessee and about halfway there as I'm going around an on ramp, they all came on. The nitro still drove fine. When we got there and let it sit for a while, they went off and stayed off until today. They came on again and the nitro kind of jolted when they did. I went home and they went off till I was on my way to work and in the middle of the highway, they came on and the car became unresponsive (gave it gas and nothing happened) I had to pull over for a minute to give it a break. I've had this car for almost 2 years and never had this problem before. Any ideas?
