My service was my 7500mile warranty LOF. I began with a phone call to Service to schedule my appointment time; said I need my 7500mile warranty LOF, the "other stuff" on the warranty check and I had a concern about a lose drivers side panel that was popping out of place; "please see if we can't push it back in place". Three days later I am contacted by Buick; "are you aware you have a 7500 warranty service coming due?" was the email. It reported the price of your LOF's. Having paid for the oil changes for life; I returned reply and asked if it was in my account that I paid for all oil changes already. In same reply I again mentioned the drivers side door panel. Three days later after receiving no reply from Buick rep I called Service. Reported what the car needed including driver side panel service, asked about my account, verified it showed paid oil changes for life of ownership. Two days later I get to Buick for service. Am greeted by the head of the LOF team who knows about my "other stuff" that needs to be checked, nothing about the 7500mile warranty service(other than the LOF) and wasn't told about the drivers side door panel. I must ask; where in hell has communication and listening to the Customer gone? The last I went to Service was due to a "ping" sensor going off on my car. The Service rep at the desk told me Arco gas was bad and that he only used 94 octane in his Audi when I told him I was using Arco 92. He said he looked on the GM website and it says Arco=bad. I pulled out the car manual and showed him the Top Tier link in the manual which lists Arco #2 in the Top Tier listing. Fuel snob at the Service desk?
