The car was filled with chevron supreme gasoline on Thursday, June 16, 2005 on my way to pick up my wife at the phoenix international airport. When I completed the task and started the automobile the fuel gauge and the hud did not agree. The fuel gauge was on empty and the hud at one-half full. I drove to the airport and picked up my wife. I returned home and pulled into the garage for the night and the fuel gauge and hud did not change. Once inside my home, I wrote an email to mitch congdon, who is the service director at van Chevrolet in scottsdale, Arizona, describing my dilema. In addition, I let Mr. Congdon know that my wife would be bringing my car in on Friday so that the problem could be investigated. I also took digital pictures of the fuel gauge and hud after pulling the car into the garage for the night. When my wife started the car in the morning the fuel gauge and hud readings matched at full. Van Chevrolet replaced the left fuel tank sending unit. Perhpas it was an error, but the mileage on my invoice #600182 was ~3,000 miles more than the actual reading. The right one had been replaced in August 2004 after the identical symptoms occurred. In addition, I used only chevron supreme gasoline and added a bottle of techron to the tank every 3,000 miles. On Saturday, June 18, 2005 I took pictures of the fuel gauge and hud to further record the readings. The pictures are time and date stamped. It is disconcerting to me that I own a world class sports car that I have to use the trip odometer to gauge the amount of fuel in my gas tanks. It is my understanding that GM has been aware of this problem for quite some time, and that there has been a recent fix involving new computer boars that are in short supply. This evening I am going to send an email to mitch congdon of van Chevrolet to inform him of my continuing problem.
