2/23/2009: Leaving stop light, car quite running and I pulled to side of road. Could not restart the car. Car was towed to dealership. Found out car was out of gas, but gauge showed a little over a 1/4 tank. Dealership said gauge cluster was defective and changed the cluster. 7/12/2009: At 25 mph car quite running and I pulled to side of road. Car would not restart and I knew I was out of gas again. The gas gauge showed just under 1/4 tank. I got some gas and went to the gas station. The gas tank holds 19 gallons, but I only able to pump in less than 16 gallons. I think something is wrong with the fuel pickup, not the gauge. I was lucky that this did not happen during higher speeds and traffic.
