“The initial time (3/14) it occurred, I was out of town with my family, embarrassed to say the least. However, mainly uncomfortable, tired, and frustrated because my 87 years old dad was stranded for hours as well as my 66 years old sister who is recovering from cancer. This problem was a serious problem because of our location. We had gone to get dinner and ice cream after getting ice cream we back in the vehicle for it would not start. I called 911 no police ever showed nor would even stop to assist. …”

“My fuel level sensor is failing to tell me the true amount of fuel left in the tank. I often says that the tank is empty but many times it changes from 3/4 full to 1/2 full and sometimes back up to full then empty. I replaced the fuel level sensor and is now working. I do have the old sensor available. 2006 Envoy Denali Xl.”

“In february I was driving home with my 5 year old daughter on the thruway, when suddenly the car stopped working. I luckily pulled over to the shoulder but had to wait there in the dark, terrified that we would be hit from behind, as it was dark. Imagine my surprise when I found out the car was simply out of gas! The gas gauge did not read empty but that was the problem!! Since that time I have run out of gas several more occasions, once with 5 children in the car at night. Gmc is not issuing a recall and it needs to be done now!! …”

“Ran out of gas with the fuel gauge reading half full (vehicle had approx 50k mileage). After putting a couple of gallons in the tank went to the gas station and filled the tank. When the vehicle was started the gauge bounced to full and then to empty. It began bouncing up and down continuously, sometimes settling at half full or at empty. It continues to do this today (9/16/13) but mostly stays on empty with the fuel gauge light on all the time regardless of how much gas is in the tank. We now use the trip odometer to gauge the distance we travel so we know when to refuel. …”
