“Gas Line corroded near Driver rear wheel due to design of gas line bracket/shield. A bit of research finds that this is not an uncommon occurence and is solely based on the poor design of the shield. Gas leaks on driveway and smell of raw gasoline promoted the finding of this issue. It required complete replacement of gasl line and a total of over $1,000 in total cost.”

“I have a major fuel leak in a fuel line close to the drivers side rear wheel . It's so bad that it was leaving a line of gas on the road as I drove. It smelled of gas a few days prior but I was unable to tell where it originated from.”

“On July 17,2018 I saw my 2008 Chevy Cobalt was leaking fuel in my driveway around the driver's side rear tire. I had it towed to my in-town mechanic, as I have Triple A. Paid $613.37 to replace the fuel line. On August 15th, 2022 same exact problem on my 2010 Cobalt. Another $553 to replace the fuel line. Chevrolet sent out a very confusing POSSIBLE recall letter in March 2013. But never officially told owners they would fix the problem with a recall letter. There have been many complaints on this problem on 2005-2010 Cobalts.”
