I have a 2012 Dodge Ram 1500 Sport with about 120k on it. I bought it used with about 60k on it. Today my ABS indicator light, SRV 4WD indicator and my traction control indicator all came on and stayed on. When I was driving, approaching a red light I applied the brake, the traction control engaged on dry pavement for a moment and then applied the brake. How serious is this issue? I am currently unemployed and have been for awhile, I cannot afford repairs. Is this a cheap and easy fix or should I take it into the shop?
