Three problems related to tank filler pipe and cap have been reported for the 2006 Chevrolet Trailblazer. The most recently reported issues are listed below.
I drive a 2006 chevy Trailblazer. After refueling the truck, I noticed the gas cap did not lock properly and the fuel gauge started to jump from empty to full. The check engine light also came on. I immediately replaced the fuel cap but the fuel gauge continued to read inaccurately over the next several weeks. Shortly thereafter, the gauge always reads empty even with a full tank of gas. A chevy mechanic told me the problem was a faulty fuel gauge sending unit in the gas tank. He said the repairs would cost ~$1,000. I cannot afford the repairs and it is a safety hazard to be continuously checking the mileage odometer to assure I don't not run out of gas. My boss has a GMC envoy with the exact same problem. I quick search on the internet reveals several hundred if not thousands of complaints about the same issue. I have almost run out of gas while driving. This faulty gas gauge is a serious safety problem that gm should take ownership for and not require car owners to repair.
1. Not sure what caused the original failure, but I would say it started after I filled my car with gas 2. It was every time I filled with gas for the first few months, now it is constant and every time my car is in motion. 3. Nothing has been done to correct the problem as the car is out of warranty and cost is well over $800, also they are unsure of the exact problem. Details: my fuel light on my car reports that there is no gas in the car even after filling up. The engine light also comes on because of this and causes issues with the car. It is out of warranty and the deal says it is could be any number of problems with the fuel system that would cost over $800. It is very scary because of the warnings that come on the car. It started after filling with gas and before would be normal after driving about 20 miles. Now it is constant. When I first start the vehicle it works fine and tells me the range, but as soon as the car is in motion it goes back to empty. Have replaced gas cap and other things as suggested, but the problem is now constant and at times while driving I can smell gas very strong. It lasts for a about 10-15 minutes and is frightening, the dealerships says it could be the pressure in the gas tank. It is very scary and very expensive for an issue they are unsure of. I request you investigate this because it appears to be a problem that the dealership knows about and refuses to do anything about unless we spend the money for them to fix something they are not sure of and have been given about a 50% chance the problem returns.
Filled my vehicle up with gas and my gas gauge reads low fuel. Poor equipment is the cause this happened on a new SUV and they should fix them. The cost is over $500. 00 dollars I understand that maintenance is my responsibility but a new truck should not have issues such as these. Also sometimes the transmission goes in neutral when I'm in drive and I lose power. The tech's cant find what the problem is. Also a code for the purge valve is on and the dealer cant find the problem. Please help .
