2010 Chevrolet Cobalt engine problems

“My car had a fuel pump go, then within MONTHS, another. We then dealt with the SAME problem symptomatically, and was told it was the fuel pump sensor. Within the last few weeks, I am having all the same issues-including the car intermittently not starting, gasoline leaking from the vehicle, both noticably missing from the gauge (i.e 1/8 tank less than night prior), odor of gas in the car, stalling out while driving and trying to start it, but also now dripping gas from the car. A new issue popped up, which is the dash light coming up saying "check gas cap". This past Thursday, my car wouldn't start again, and has not started since. It's concerning that the Chevy Cobalt has had recalls for the same exact problems, literally thousands of complaints that mirror mine- for every model year EXCEPT the 2010. It's also interesting that they also stopped producing the Cobalt entirely in 2010 too, but considering the amount of faults and issues I've seen documented in every year model it's not a shock. I'm concerned that despite the amount of complaints that include 2010 models, they were excluded from the recall and seeing that my situation is another one that won't be…”

“I PURCHASED A 2010 CHEVROLET COBALT FROM A USED CAR DEALERSHIP IN JULY OF 2019. 3 MONTHS INTO HAVING THE CAR, AS I , MY MOTHER AND 6YO DAUGHTER WERE DRIVING ON THE HIGHWAY AT APPROXIMATELY 60MPH , THE CAR STARTED TO JERK AND SLOW DOWN. THE 'ENGINE REDUCED POWER ' MESSAGE CAME ACROSS MY DASH . WE WE'RE ALMOST SIDE SWIPED AND REAR ENDED. ONLY FOR THE FACT THAT A FELLOW MOTORIST STOPPED BEHIND ME TO HELP MERGE TRAFFIC TO KEEP US FROM GETTING HIT , IS WHAT KEPT US FROM BEING IN AN ACCIDENT AND PULLING OVER TO THE SHOULDER. THIS IS SO DANGEROUS AND I CAN'T IMAGINE AS A MOTHER HOW LOSING HER LIFE, OR THE LIFE OF HER CHILD WOULD HAVE BEEN DEVISTATING BECAUSE OF A MANUFACTURER'S ERROR!”
