My daughter was driving to a friends house. She lost all power, and the vehicle would not start back up. There was 3/4 tank of gas in it. We had it towed to a nearby shop to have it looked at. Upon the vehicle leaving it had a lot of gas on the gravel road. When it made it to the shop there was obvious fuel line issues. This vehicle has not been fixed yet, still waiting on a replacement line from a dealership. This is something that gm should have had recalled and fixed immediately. This might have been an issue that would have been fixed due to it still under a manufacturers warranty, but I do not have access to that. The shop where the work is going to get fixed at said this was covered up to 150,000 miles. If this was an issue to that mileage, it should be extended to the life of the vehicle.
After stopping at mailbox the low fuel illuminated, the fuel gauge indicated empty. The tank was half full prior to the 12 mile trip home from town. Not sure when the problem occurred, because it might have taken a few minutes to pump out 8 or 9 gallons of gas, however it was on this12 mile trip home. 6 miles of highway at 55 mph and 5 miles of paved county road at 30 mph and 1 mile of gravel road at 20 mph. After the low fuel indication the engine was stopped, fuel was added from a container, and when the engine was started the fuel streamed out on the ground. The vehicle was towed to a local repair facility, because it was closer than the dealer. Gas line and clamp were replaced. The mechanic indicated the plastic gas line and plastic clamp were hanging low, and no protective cove over it.
