Ok i think this is alittle outregous, but i might be wrong. I usually do all my own work though i have an extended warranty on my ls. I went to the dealer ship because my airbag light was on and my a/c compresser seems to be making a noise. ALso my traction control light came on and stade on. It went off the next time i cranked the car. So they are going to charge my warrnty company 127.00 to diagnoiss and individual item. So that is 375 to figure out what is wrong. Is this high or am i just not with the times?????
