“The contact’s wife owns a 2006 Chevrolet Cobalt. The contact stated there was an abnormal fuel odor inside the cabin of the vehicle. While exiting the vehicle, the contact became aware that there was an oil leak underneath the rear end of the vehicle, and the fuel odor was more evident. There were no warning lights illuminated. The vehicle was jerking while accelerating and while driving from being stationary. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.”

“The car idles very low when stopped and sputters/putters like it's going to die. It has now actually died on me twice while driving, luckily when you put it in park and turn the car off and back on it starts right back up but you can see how this is a severe safety hazard. The first time it died I was stopped in the turning lane waiting on traffic to go by so I could turn left (this is the busiest street in town) I go to start turning left the car just shuts off mid turn crossing the other lane of the street, luckily I didn't get hit by oncoming traffic and was able to coast onto the side street that I was turning on and pull over and turn the car off and back on and drive it home. I took it to the mechanic and he can't figure out what's wrong with it so he gives it a tune up and now the check engine light won't turn off...fast forward to today it dies again at a stop sign with my [XXX] in the car. It is ESPECIALLY bad if you have the AC on it seems like it effects the electrical like the car is going to shut off when I am stopped and the ac is running, so I turned off the ac and it was still sputtering when I would stop but didn't die again. There is an entire…”

“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…”

“The problem that sent it to a different mechanic than the chevy dealer where it came from after a month and 900.00 bill for 550.00 ecm and diagnostic test they did without my permission, there labor for the test and ecm was a total of 900.00. Plus claimed it was throwing a code for a peddle that it needed. We just put a brand new peddle and brand new throttle body on it, it was idled to high, so reason for them getting it was to get the old ecm and new throttle sinked up to reduce the idle , at the time of it leaving me it started and ran just idle to high. Throwing no codes. They got it, claim it wouldn't start so did a diagnostic claimed it needed a new peddle. I said I'm coming to get it, they didn't tell me at any time I couldn't drive it home. I left there lot and pulled about 150 feet off the side of road because it wouldn't shift. Called them , botched did no good. Called same tow truck to tow it home. Got here it was idled normal but was throwing a different codes, I turned the car off it wouldn't stop running for about 3 to 4 minutes, then it died. I had it towed to different mechanic for the ignition to be replaced. He said it was throwing a couple…”
