Today with the fuel gauge showing 1/2 tank full, my Acadia ran out of gas and I was forced to the side of the road. I have seen recalls for other year models for this exact problem, but the year my Acadia is does not matter to gm. This is a very serious problem that could cause a severe accident. Gm's recall number is 14007. In the affected vehicles, the engine control module (ecm) software may cause the fuel gauge to read inaccurately. An inaccurate fuel gauge may result in the vehicle unexpectedly running out of fuel and stalling, increasing the risk of a crash. They know there is a problem why not fix it.
