I was told I needed the Soft ware replaced that notified me of any problems with my car. I said yes and the invoice said "ran diagnostics found PO449 PO455 leak tested evap system found fuel cap seal cracked PCM CAL update for false codes recalibated PCM -- replaced fuel cap- cleared codes ok now" The bill was for $220.29. Labor was $162.88 and parts $34.85 Tax $14.42. Did I pay too much for this service and did they really replace the soft ware??

The price may be a bit on the high side but not by much. They may have very well replaced the software but it could be very difficult to prove one way or the other. Most software undates are done through a General Motors website. GM may keep the update records on file. Perhaps you can try calling G.M. customer service and see if they can help you.
