   Car has developed a fuel leak once again in the rear of the vehicle. this is the second time a fuel leak has been noted. the first time the mechanic replaced a portion of the line that had corroded and was leaking fuel near the driver rear tire. now the leak is in another section of the original pipe near the fuel tank. this is poor quality and engineering.

   Fuel line leak. My fuel line has cracked in multiple places and needs to be replaced entirely. The leak was consistent, with a constant stream leaking out when in operation and for several minutes after stopping the engine. The odor of gasoline was strong from inside of the vehicle when in operation and large puddles of gas were visible on the ground afterwards when I first noticed the issue. My repair quote is about $500 to get the line replaced entirely.

   Body clips holding fuel line causing rusting at these points. Leaking fuel from body clip in front of driver’s side rear tire. Based on caked on debris (mud like consistency), it has been happening for a while but wasn’t leaking to driveway due to disuse of the vehicle. This has commonly happened on 2008-2010 HHRs and Cobalts too.

   I have a fuel line leak near the left rear tire which has been happening with other vehicles such as the cobalt and other hhr's. I took it to a dealer and they said it is going to cost me $1500 to replace all the fuel lines because they were rusted really bad. This shouldn't be happening plus it's not very safe. This should be a recall item. My vehicle only has ~156000 miles on it. Thanks

    My 2007 HHR (I also hve a 2008 with the same issue as this) was being configured with replacement front seats and after completion the mechanic/installer informed me that there was a strong gas leak on the driver's side. Upon looking at the car a very noticeable puddle of gas was on the ground. I had the car moved to my home and it is currently unable to use due to the gas leak. This is ridiculous. Everything I have read points to Chevy cheaping out and not using…
