One problem related to other fuel system tank mounting has been reported for the 2006 Chevrolet HHR. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 Chevrolet HHR based on all problems reported for the 2006 HHR.
The chevy Hhr was built with steel fuel lines running from the fuel pump outside the fuel tank across the front of the tank to the drivers side of the vehicle where they turn and run just above the exhaust pipe. To prevent heat buildup the fuel lines are wrapped with an insulating tape of some sort. This tape loosens over time and allows water to accumulate within the wrapping of the fuel lines. This causes the fuel lines to rust to the point of failure wherein the fuel then leaks out very near or onto the exhaust pipe. This is a fire hazard and could result in the injury or death of any occupants of the vehicle in the event of a fire or explosion of the fuel tank. Although this is a problem with the design of the Hhr, Chevrolet has yet to do anything about it. I was told by my local dealer that the entire fuel line system from the tank to the engine would need to be replaced at an estimated cost of $1000. I discovered this when I parked my Hhr in the driveway and smelled fuel. My vehicle is leaking fuel and is not safe to drive. I own 2 Hhrs, a 2006 LS, and a 2009 ss, and am now looking at a $2000 expense just to make them safe to drive. This should be the responsibility of Chevrolet, not every owner of a Hhr.
