Wiring harness is located too close to the human under the driver's seat. Exposes the driver to electrical frequencies that could be avoided if the wire harness was a further distance away from the human. Also, the the fuel line rusted through after 9 years about 9 inches away from the rear axle where the metal tape ends around the fuel line. The metal tape seems to allow more moisture to become trapped around the fuel line; which promotes rust and a leak where the metal tap ends. After the metal tape, the fuel line is in good condition on this specific vehicle. The fuel leak is about 0.5 inches wide and a lot of gasoline drips / leaks after the car is started. The rust particles are located after the fuel filter; which may promote the rust particles to reach the engine via the rusted fuel line. The car has trouble starting (a delay) and needs to have the key turned twice due to the leak. The leak is very close to the muffler, so it seems like it would be at risk of catching on fire if the muffler was hot enough or if it were traveling on a long trip or going up or down a steep hill. The vehicle has been inspected by police. There were no warning lamps or lights.

I bought a used 2009 Chevy Cobalt 2 years ago in 2017 with 119K miles. It has been nothing but a headache with things going wrong! the biggest issue is the code P2135 that sends the car into reduced engine power and the engine shakes violently. This is very scary especiallywith 3 young boys in the car with me. I have replaced the entire throttle body, ECM, accelerator pedal assembly with new sensor, crankshaft positioning sensor, camshaft sensors, spark plugs and spark plug wires. After all these things I am out of ideas onwhy this keeps happening in but all those new parts have not fixed the problem that keeps occurring. Please tell me there is a recall or you can at least tell me what the problem is. I have read many forums about people with this same issue.

The vehicle anti theft light keeps coming on. When this occurs the vehicle jerks in drive, hard to stop, wheel will lose power steering in drive, and all needles will move. The RPM, mph, and gas needle continues to fluctuate. The gas needle will indicate low fuel when fuel is present. I can never know what speed I'm doing. The vehicle flashes power steering digitally. The car will shut off in mid drive! taken to many mechanics including dave gill Chevrolet and no one fully diagnosed the issue!

Hello, I have a 2009 Chevy Cobalt. It was running okay. I went to the store for some dog food. Parked the car, came back to go back home and the key 🔑 in the ignition would not turn. It was locked or jammed, don't know. Key would not turn in the ignition switch to turn the car on!!! I went to the internet and found that there was a recall from General Motors on my 2009 Chevy Cobalt. I found a NHTSA campaign id# 14V171000 that shows the recall for my car. It describes an ignition switch recall. I called the chuck nash Chevrolet where I bought the car and they told me that they had repaired the recall. Apparently they repaired it with a defective ignition-switch or not at all. The recall states that some vehicles were repaired with defective or used parts. Mary barra, General Motors CEO stated that all affected recall vehicles would be repaired up to customer safety standards. I really need your help in this matter. This car is my only means of transportation. Thanks. God bless.

After driving car approximately 4 miles on county roads, at 25-35mph. I arrive at my destination, stop, shift into park, and reach to turn key off. I am unable to move key from the run position, and/or remove the key. So my car is sitting there running and I am unable to turn off the engine. After nearly 10 minutes trying to turn the key back to off while jiggling the key and the steering wheel, and shifting the gear shift down and back to park several times, I am unable to regain control of the ignition switch and key. I resort to pulling a fuse underhood to kill the engine.

Wiring harness in driver's side front door creates an electrical short that disables side impact sensors/airbags. Symptoms match exactly the an existing recall (15V500000) that lists only the 2010 model year as being affected. The disabling of the airbag happens every time the driver's side window is rolled down. This occurs when driving and stationary.

This has happened twice, my car wont start and the anti theft on the dash comes on but there's nothing on to kill the battery. Also sometimes while driving my service air bag light comes on but goes off right after. Last thing is my power locks would go crazy just locking and unlocking either when the car was off or in motion.

Electromagnetic meter (emf meter for both wireless & non-wireless forms of electrical radiation) used to measure electrical radiation levels read high levels of radiation that the meter felt was over-the-limit only when powering the vehicle on buy turning the key (with a battery & gas in the vehicle). The increase of electrical power seems to be the cause of the meter increasing. There are many wires that were under the seat that are setting off the meter when held within 12 inches of it (in the area the driver & passenger would sit - on the seat). Perhaps, a recall and electromagnetic shielding needs to be added in the area where the passengers and drivers sit.
