Gas gauge sometimes works and then stops working. I never know how much gas I have.

Trailblazer EXT ES V6

  • Automatic transmission
  • 100,000 miles

A faulty gas gauge is extremely dangerous. Not knowing how much gas is in the tank leaves my (or my son) guessing as to how much gas is left. Stalling out in the middle of the highway can cause a serious accident! PLEASE, PLEASE make this a recall!!

Chevrolet dealer charging double the price for parts:

I have a 2006 LS Trailblazer. It recently began having problems with the fuel gauge going haywire …reading empty when there was a full tank of gas. There is a “partial recall on this vehicle and many other GM vehicles showing this problem. At first GM was going to pay for half of the fix which includes the part=19177712 sensor kit and half the labor. Recently they decided to cover the whole cost as there are many vehicles with this problem. The vehicle must be under 120000 miles or 10 yrs old or less.

At first I was glad GM stood behind their cars. But going to the dealer is another BIG problem. When they get your vehicle and take it apart they say you should replace the gas hoses and sending unit associated with this problem. Cost =$120 dollars Then they say you should replace the pump and sending unit part no. 19153374. Cost = $533 plus 36 dollars tax. The whole job is now 700.00 dollars. The big rip off is this: If you look this part up …and make sure it is an OEM part so it’s apples to apples…the part can be bought for $249 at shopchevyparts.com and at Amazon whose price was $307 includes free shipping or GMDirect.com which is a supported site with GM. That makes the dealers price TWICE! what you can buy it on line for.

We all expect dealerships to be more expensive but when they rip you off at twice the price on ALL parts , you really get a bad feeling and you know you have been taken to the cleaners. My feeling now is I would never buy another GM product…nor would I ever go to a dealership for repairs. Way too costly . Even though they paid for sensor and labor which is about 400 dollars I wound up paying $700 for the fuel pump and hoses units. My advice would be to buy the parts yourself and have an independent garage or yourself fix it, you'll come out ahead.
