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.

Vehicle has a fuel leak from rear of vehicle. Smells of fuel in cabin. Found shields wet with fuel. Seems there should be some recall on this. This is the 2nd cobalt I've owned with the same issue.

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.

The fuel lines on this 2008 cobalt have rusted out and leaving a visible fuel leak puddle after parking. The leak occurs in front of the driver side rear wheel. This area has a heat shield over the fuel line underneath which traps moisture and road salt. This leak has caused me to park my vehicle outside as a safety precaution and not drive it. The leak is near the exhaust which is a large safety risk in my opinion. I am taking to the dealer to have them confirm and quote out repair cost.

I have to replace my fuel lines due to them rusting out over the left rear wheel well. I noticed a distinct smell of gas for a couple of rides to or from work. After a couple of rides, the smell was very strong and I happened to notice the gas dripping down under the car upon inspection. It was taken to a auto repair shop where I was told that this was a serious hazard and the gas lines would have to be replaced costing me $650. The mechanic said that the lines has rusted causing the leak. He also mentioned that this was a common problem with the 2008 chevy cobalt.

The fuel line rusted through and were leaking gas right next to the exhaust pipe! This should not happen!!! I-€™ve never had to replace fuel lines due to rust on any vehicle I-€™ve ever owned!!! Inferior metal and or poor design had to contribute to this! Thank God the car didn-€™t start on fire or blow up. My friend has a 2009 Cobalt and had the same problem!!! It cost me $1478.79 to repair this defect!! No warning other than the terrible gasoline odor!!! Please do something about this before someone is killed!!!

The fuel system has developed a small leak, for now near the left rear tire. I cannot pinpoint the exact location of the leak due to the heat shielding around the lines. My concern is the proximity of the fuel leak to the exhaust system and potential fire hazard. A dealer has not looked at my car, however I have performed maintenance on enough vehicles and aircraft to know when there is a fuel leak. There are no warning lights associated for the leak thus far, there is a tendency for the the vehicle to need to prime itself by cranking in the morning or in cold temperatures.

My 08 Chevy Cobalt has major fuel leak leaving puddles by left rear wheel. Very strong smell odor, losing more gas than putting in. I lost 5 gallons of gas in a 3 mile radius. Took to a repair shop and mechanic said the fuel lines are rusted from one end to the other and Chevy(GM) does not make fuel lines for a repair. At risk for car blowing up.
