I had taken my veh in to the dealership. Sometimes my veh would not start, I picked my veh up on the friday the dealer ship told me my veh was perfect they did all the test and even mentioned my battery was like new. Well I was away from the city parked my veh. when i went to start it it wouldn't had to call GM road side assistance to come get myself and the veh and tow it back to the dealer ship. Come Monday morning they didn't even no what to say to me. The veh. and GM are crap never buy one !
