Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The fuel tank has an evap leak that somehow breaks on top the tank so it leaks the gas vapors and could potentially start a fire but the part that breaks is a non serviceable part so it can’t be fixed without purchasing a whole new gas tank that isn’t cheap. My other concern is the infamous grounding issue with the wires on the ground g105 I believe right next to oil filter that grounds the transmission and engine control modules well it shorts at times when driving and suddenly your car dies while driving how scary it could cause a wreak and kill somebody it’s a very scary issue that constantly comes back even after trying to re ground it needs to be recalled and fixed it’s going to kill somebody and it’s a well known issue for this make and model that should have already gotten attention to be resolved.

Before I get into all of it there has never been an accident not yet at least. I do everything I can to try an stop that from happening, (but accidents do happen) only because I know my car could kill on me so I’m extra careful. 1) After I get gas I’m my car the car won’t start right away. I have to restart it a couple times an step in the gas an rev up wasting the gas I just put in to get it to start. 2) When I stop an start to pull out of somewhere on to a main road the car will just die on me so I’m stuck pulling out in traffic trying to get my car to start again. It’s when I come to a stop an pull out it just kills on me. So I have to make sure no one else is coming an I have enough time to be able to restart it otherwise I’m worried when I pull out of anywhere or stop an go that another car will smack into me because my car just died on me in the middle of the road/ pulling out an crossing lanes. SUPER SCARY! 3) Let get into the next issue so anytime I run my ac my car starts to do this jumping thing like it wants to kill on me not to mention it has killed on me with the ac on (I live in Louisiana an it’s too hot not to have ac plus I have 3 kids) what’s sad is the ac works fine but if you want the car to maybe not die then turn it off an you have a better chance of it not killing off on you but not always a guarantee. So ill run it for second to try an cool down so I’m not drenched in sweat but I have no other choice to turn it off so the car doesn’t just die on me. This refers back to the 2nd problem I make sure it’s off anytime I pull out of anywhere thinking that would help it from killing on me while trying to get out of anywhere but it doesn’t but I can tell you If the ac is on when I pull out when I start to go it dies right as I’m in the middle of the road every time never fails. Mechanics have replaced parts trying to fix the issue, but it still happens I can’t keep buying/fixing things for nada, ongoing problems since buying.

Fuel line leaking similar to the recall on 2008-10 Cobalts -- gas puddles or drips from leaking fuel lines near the left rear wheel well, near the exhaust pipe and muffler. The leak is caused by corrosion of the metal fuel lines that are secured to the body of the car by plastic blocks.

My 2006 Chevy Cobalt has a fuel leak which was recently a recall. I have been told by several dealerships that it will not be repaired for free. How can this be? I didn't know recalls expired. It's a safety issue and the manufacturer's responsibility. Please advise me on next steps.

Last year or so, even before than, I noticed suddle fuel odor smell & noticed few drops by left rear wheel area...it has progressingly gotten worse and now puddles and smells of fuel constantly...all which I traced back to fuel lines by rear exhaust heat shield area where it's very rusty, inline elsewhere around car area...seems to be bad design and or manufacturing issue...also very common I noticed with cobalt saturn Pontiac models sharing same design & platform.. Very dangerous and needs to be corrected by gm!

My headlight an blinker quit working new bulbs an all new wiring it it still will not work My trunk button also just stopped working an the fuse is not blown. I even replaced it just to make sure still nothing. Door panel clips won’t stay in bought new ones same thing so now my handle is coming apart an my door doesn’t want to shut bc it thinks I’m still holding the handle.. Fuel everytime I get gas I have to crank my car a few times and press on the gas before I can get it to go otherwise it just dies on me I’ve had it looked at they said it was something about how my car does not know when to stop releasing air I think. My blinkers don’t turn off unless I do it manually. The seals on my door is no good anytime it rains it’s coming inside of my car an since the door panel won’t stay on it’s coming straight into my car

I began noticing a slight drop in fuel mileage at first. Started smelling fuel while parked and only getting 200 miles to a tank. Noticed the supply and return fuel lines where damp. Dropped the tank and the fuel lines at the pump were cracked a little. I temporarily fixed thos with jb weld but dont expect it to last.

Fuel lines are rusted where the heat tape is around them by the exhaust. This has caused them to rust and no is leaking fuel. I am worried that it's going to catch fire. This is my daughter's car and is a very poor design.

There is a recall for some vin numbers on the 2006 Chevy cobalt (recall # 09V419000). My vin number was not included but the exact recalled part was also defective on my car. I wanted to let you know because there are probably several more vins that should be included in this recall, as my car is proof of that.

THE COMPANY WRAPPED A HEAT SHIELD FIBER AROUND A BARE METAL FUEL LINE CAUSING PREMATURE FAILURE OF THE LINE IN THAT SPECIFIC LOCATION DUE TO RUST FROM THE TRAPPED MOISTURE. THE FUEL LINE BURSTS CAUSING A STEADY FLOW OF GASOLINE TO POUR FROM BENEATH THE VEHICLE CAUSING AN EXTREMELY HAZARDOUS SITUATION. THE CAR CONTINUES TO FUNCTION, LEAVING A TRAIL OF GASOLINE EVERYWHERE YOU GO. THE HEAT WRAP DOES NOT APPEAR TO AFFECT THE BRAKE LINE DUE TO IT'S BLACK COATING. THE FUEL LINES SHOULD ALSO BE PROTECTED IN THIS AREA.

MY VEHICLE, A 2006 CHEVY COBALT LT, LIKE MANY OTHER CHEVY COBALTS I'VE FOUND IN MY RESEARCH, HAS A FUEL LEAK IN THE REAR DRIVER SIDE. I HAVE NOT PINPOINTED THE EXACT LEAK LOCATION BUT I HAVE A PICTURE DISPLAYING THE FUEL LINE COVERED IN WHAT SEEMS LIKE AN ALUMINUM FOIL TO KEEP THE LINES FROM HEATING UP. CLEARLY THIS DOESN'T WORK. THIS IS A COMMON ISSUE AND I BELIEVE IT NEEDS TO BE ADDRESSED.
