Fuel & propulsion system
1. On 5/19/2011, after filling my 2006 Chevrolet Trailblazer with gasoline, I noticed the gas light had illuminated on when pulling out of the station parking lot. I drove down the road two-three miles before pulling over and letting the car sit for 20-30 minutes. Upon restarting the engine, the gauge moved to 1/4 tank, and then dropped back to empty. I drove home, and upon starting the engine the next morning the gas gauge was still showing empty. After 2 days, the gauge moved back up to 3/4 tank. On 6/1/2011, I had 1/4 tank and refilled, only to find the gas light illuminated a second time after fueling. The gauge is currently reading 3/4 tank when just filled yesterday. 2. In response to incorrect gasoline gauge in my Trailblazer, I have begun paying close attention to miles driven and resetting my odometer at each fill-up. …
Gas gauge is not working properly. I can fill the tank and it will say that my fuel level is low, 2 blocks later it will say I can drive 240 miles and the needle will also go up, 4 blocks later they are both back down to only 64 miles for example, then back up again and then it will ding an alarm and say fuel level low. I have no idea how much gas I have in my tank ever. This is not safe for my son and I to be driving around not knowing when the gauges are working. What if we are out of town or on a country road or a bad area of town? Please recall the sending unit so we can all get this problem fixed. There are many complaints about this faulty part. Please do the right thing and fix it. I do not have $500 to spend on my vehicle.
