New owner as well here. Picked up a Summit in white.
Had an issue with a loose crank position sensor connection that caused my engine to start shuddering and engine light to come on. Had it looked at and found out a recall and a couple RRT's need to be done as well.
Overall, I love the vehicle so far. Too many gadgets and crap to mess with, especially coming from an old Tacoma and my current G8 which doesn't have all the goodies that this truck has. Been getting a lot of compliments from friends and co-workers on it.
Pic of my Pontiac G8. I have it lowered about 3/4" in the front and a little over an 1" in the back with Pedders GSR struts and shocks with their lowering springs.
