I first had noticed my front passenger speaker would cut in and out. It didn't matter if the car was stationary or if I was driving. The following week I was driving through the parking lot of my job and the doors locks started locking and unlocking rapidly by themselves. And now they rarely ever do either when I try and push the lock buttons. So they either have to stay locked or unlocked depending the mood of the car. The following week I had a gas leak and had to have it serviced because that is very dangerous. The mechanic told me that there was a recall on that plastic piece to fuel system but only in southern states and I live in the North. And not to long after that my turn signal switch wouldn't stay on or it wouldn't shut off by it's self. Also dangerous trying to hold switch on while making a turn.

Strong gasoline odor from vehicle when parked and during operation. Very likely same problem addressed in NHTSA campaign 09V419000. Recommend that recall should include all model years with faulty fuel pump assembly, and should apply nationwide, not just "hot" states.

The contact owns a 2008 Chevrolet Cobalt. The contact noticed a strong odor of fuel and noticed fuel leaking underneath the vehicle. The contact stated that the fuel gauge was not working. The dealer (sunrise Chevrolet Buick GMC, 4605 S houston levee rd, collierville, tn 38017) was contacted and a technician informed the contact the dealer would not be responsible for the repair cost since the vehicle was not included in a recall. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 263,000.

The fuel line rust out and leaks gas. This is a very dangerous situation but apparently not covered by recall 12V459000. This gas leak should defiantly included in that recall. My car is driven by a teenager and he did not notice the leak until I saw it. The repairs were over $800. This happened to both of our Chevy Cobalts in the same week.

I reported this back in 2016-1-28 ref.no.10822806 gas line corrosion problem, do to muffler right under gas lines and gas line up in pocket where heat and moisture cause early corrosion(poor design). GM had go me to a dealership and confirm corrosion problem (wanted 750 dollars to fix). Talk to rep.for GM, mentioned I felt poor design and protental safety =may cause fire. Did have fix at garage for 200dollars. Now corroding again after 2yrs. This confirms gas lines in pocket up above muffer traps heat and mositure causeing corrosion. Please advise company does not want to listen to me and I can't afford to replace gas line every 2yrs.. feel strongly about poor design and GM should be responsible. Fire hazard this is same car that had key problem, steering problem, gas line problem at tank and gas pump, yet they don't want to listen, help help help!!!!

The dash message says power steering. As I was excellerating in the on ramp of the highway, the RPM jumped up to 6,000 all on its own and now it will not shift gears, does not read any mph, and can barely go more than 20mph. This was unexpected and had no warnings prior to. Although it still functions (turns on, runs, has all power available, has reverse) it is ultimately disabled. Also, the fuel lines/ fuel pump failed causing a gas leak, making it a challenge to start the vehicle. I have patched the fuel line as a temporary fix. I have already replaced the lower control arms and the timing chains at my own expense

I woke up to find that my car was leaking fuel. There was no accident or incident. The leak is from the rear driver's side. This seems to be described in other 2008 Chevrolet Cobalts and is covered in some cases under a recall #12191B. My VIN is not included so I was hoping to raise awareness that this problem continues to occur on cars of this year and model.
