Ok, I just bought this car, 2009 G8 V6, and I love it. Of course it was used but serviced regularly and very well maintained. I've had it about a month and at first ethng was great. Then, out of nowhere I get "ABS FAULTY" warning along with EVAP leak and a 2176 code. How are these related, if at all and what would cause them to come on all at once? CPU going out?
