My car turned off while I was driving and almost caused me to crash into an 18 wheeler. Thank God I turned on my emergency signal and the truck swerved!. I would of died. I was stuck in the middle of the road and luckily some passersby helped me push it into a commercial parking area. I tried to start it again and it wouldn't start. But, when I turn my key into the off position, my car tried starting by itself. It was scary. It was checked by a mechanic, prior to this happening, because the car was hard to start. The mechanic told me to find out if there is a recall. However, I did some research and there was a recall on the ignition switch and fuel pump. The ignition switch was faulty causing the car to turn off while moving and two people died as a result. I entered the VIN # and it didn't show any recalls.

Keep smelling fuel vapors on the rear left side of the vehicle. Checked the fuel filter and it seems to be working despite my gas mileage getting worse and worse. I've been burning a full tank of gas going less than 250 miles when I should get near 400 miles a tank.

The vehicle overheated and shutdown while traversing rt 287 near boonton at speeds around 65. I coasted off an exit and came to a stop at park ave and wootton St. While I was waiting for my vehicle to cool down so I could either fix/continue driving, it had become apparent that the engine compartment had started to combust. Noticeable by the sound of the fire. That left me rushing to empty out the vehicle of belongings in the middle of the road before the vehicle completely engulfed into flames. Note that prior to the engine overheating absolutely no warning lights nor indicators had turned on. When vehicle overheated the temperature light turned on and that was all until the vehicle was actually on fire and had shut itself off.

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.

Service engine light on along with traction light which appears when engine gets hot usually at an idle. So when traction light is on & your driving in normal traffic, car will slow down and you'll have to step on gas really hard to keep up with traffic, if and when transmission decides to shift gears it will bang really hard into second gear.
