 I have a 2007 chevy silverado and the gas gauge has been acting up for about a year now. i can fill the truck all the way up with gas, drive it home from the gas station(7 miles) and the gas gauge will be reading about 3/4 tank. when i go to drive it the next day it reads 1/2 tank then by the time i get to the interstate (15 miles away) it will be between 3/4 and full. i love the truck but wish chevy would put a recall out on there sending units because i know people with the same problem and have seen many complaints about this same issue.

 My son was driving on the highway in texas when the engine shut down and the car stopped running. he lost all power steering and could barely get off the road in time. the car had to be towed to the nearest town in gainsville. the diagnosis was the sending unit failed and in turn caused damage to the fuel pump that made it inoperable. my concern is that there was no warning light or any kind of indication that this problem was about to occur. there was no way to prevent this. the fuel level read that there should have been 1/4 to 1/2 tank of gas but the mechanic measured 1/8 - 1/4. i'm not sure if the gas level attributed to the shut down or not. that is something that i'm sure will be factored in to your investigation. i feel like this was a definite opportunity for me to speak up and take action. my son was spared from injury or death and there needs to be a solution to this problem to avoid these irreversible consequences. whether it be an indicator light or better yet redesign of the systems so that they cannot shut down the car automatically. remember he was driving 60 miles and hour on an extremely busy highway, the outcome could have easily been very grim, especially had it occurred at night. i may have been planning a funeral instead notifying people how to avoid one. please take this as seriously as i have and take action to eliminate the potential damaging effects of this type of failure. i have documentation of shop records etc. and will be happy to provide any additional information you may need to proceed. thank you for your time. *tr

 I just bought a used 2006 silverado 1500 from a dealer. went home with a full tank of gas, week later went to fill it up and the needle stopped halfway between 3/4 and full and it would not let me put it in. truck had 14650 miles on it when it started and now has 16450. still under warranty and has been to the dhop 6 times and they have replaced every part of the fuel system and still no better. the next step is to bring a gm rep in to determine what is wrong. *tr

 1. no events noted. 2. check engine light illuminates and stability traction control light illuminate periodically. when ever the traction control light is on, there is a very sharp jolt in the rear end whenever the vehicles start moving. 3. taken into the dealer twice now. no remedy. stated they through it was the fuel being used. so i have ran several tanks of fuel through it now and it still has the lights. i have made sure i purchased fuel from large dealer such as shell or conoco to make sure fuel should be good. i will take the trunk in again this week. *tr
