My Cobalt 2009 has gas leaking in front of the back driver's side wheel. This has been report it seems by several people online that I have found. Why can not GM cover this repair in a recall? I've tried to call around for pricing but most garage's won't give me a quote over the phone. The best I got was that this would cost around 2000-3000 for replacement. But it seemed like a shot in the dark on the pricing. I called the local dealership near me in Darian Connecticut, and was told that this was not covered under any recall. Corrosion protection coverage expired in 2019 from GMs site. But why would a fuel line be made of a metal that rust and is near the hot exhaust requiring a heatshield on the pipes? Aftermarket repairs seems to be either Braided Stainless Steel around Nylon, or Some Nickel/Copper Piping using compression fittings that plumbers use.

2009 Chevy Cobalt, Driving to work Friday January 13 2023, noticed heavy smell of gasoline. parked car and noticed a puddle just in front of the drivers side rear tire. Got it home and did an inspection of the area and discovered a fuel line leak when car is running and line is under pressure. It is a big leak seemingly caused by rust developing on the line because of a heat shield trapping water and debris. This leak is very close to the hot exhaust system. Fire is an obvious possibility. I'm afraid to even drive it to a shop. I plan on having it towed.

There is gas puddling around the driver rear tire. I saw an article, which can be found here: https://www.thecarconnection.com/news/1128764_more-than-600-000-chevy-cobalt-and-hhr-models-investigated-for-fuel-leaks Gas leaking is an obvious safety problem due to the risk of fire or worse. The symptoms began yesterday - February 11, 2022. I did bring the vehicle to Bob McCosh Chevrolet in Columbia, Missouri. They reported there are no recalls on that system. But as the article link above confirms, I am certainly not alone in this problem. I believe this problem is being investigated but no recall has been issued. I will also follow up with the service manager at Bob McCosh Chevrolet in Columbia, Missouri. I will escalate to the regional service manager for Chevrolet. In the meantime, it would be very helpful if the weight of the FHTSA could get behind this problem. I can be reached at [XXX] if you have additional questions. My email is [XXX]. Thank you.
