Faulty fuel gauge / fuel sending unit / fuel reading / fuel pump. I have had to have my fuel pump replaced three times now due to faulty fuel sending units. This is a major problem because my truck now shows that I am always on empty and can be a huge hazard and life endangerment. I don't want to be going down a highway at 70 mph and have my truck stall. I have replaced this unit twice already and I am now with a faulty one again. All original manufacturer equipment. No after market replacements. It seems that new manufacturer units will work for about 10,000 - 30,000 miles and then fail. This is an issue that I have seen reported hundreds of times by GM owners of Trailblazers and similar makes. My problem is with a 2006 Chevy Trailblazer V6 ls model with 126,000 miles.

Acs/ service stabilitrak light comes on while driving and to get it to go off I have to stop and turn the vehicle off and back on again. Also fuel gauge goes from full to empty even on a full tank of gas. When I turn my heat on it will only work on numbers 1-4. number 5 is completely out. Also there's a squeak in my brakes that I cant get to go away. I replaced the rotors and brakes and had 2 new front wheel speed sensors put on because I was told that was what was causing the service stabilitrak light to come on. But that didn't fix my problem either. I have been told that because I bought my vehicle used and it had miles on it when purchased that nothing is covered under a warranty.
