“The air bag never deployed I bought car in 2018 from original owner with car only having 33,000 miles on it and still under warranty til car had 100,000 miles and I hit a deer head on 2 months after getting car which bought in may of 2018 hit the deer in July 2018 . The deer was hit with the front passenger side it broke my headlight n messed my hood up and smashed in the grill little and my air bags never deployed I hit deer at 50 mph , after that had happened I took it in to Chevy dealership and had them look at car cause I told them I hit that deer and air bag never deployed and that my air bag light came on once in awhile and said service air bag . The dealership said they do that sometimes and did something to make light go off that was it my air vag light still comes on and says service air bag . Also ignition switch and fuel smell foul coming from car a lot and is as I speak . My reduce engine power light comes on a lot and have no power to gas pedal n car won’t stay running . I have try to get two recalls fixed back in 2-21 I was having problems with my car back then too special reach called me in Jan of 2021 and told me that there were two recalls on…”
“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.”
“There is a gas leak an after reviewing online there are several complaints of chevy colbalt 09 owners whos car forms a gas leak on the driver side of the car near back seat. There is a very strong smell of gasoline and seems to be a repeated issue”
“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.”
“Fuel leaking from near top of tank/pump. Sounds similar to other recalls though my VIN is not currently included. Noticed fuel smell in garage and could see fuel from top of tank. No indicators showing a malfunction.”
“The vehicle had an instance of hard starting, then I became aware of the odour of fuel in my car which quickly made me exit the vehicle as the fumes were strong. Liquid fuel was leaking out of the left rear in from of the wheel area, in proximity to the exhaust system”
