My cobalt illuminates the check engine light as well as the theft light and displays engine power reduced happens multiple times first time it started was in 12/2017. The car was purchased in 2011 always serviced and repaired by dealer ship. The car stalls at stop signs lights or when you pull into a parking lot. Engine light comes and goes. Lights dim and flicker the gauges jump up and down in the dash. After you shut the car off the gauges in the instrument cluster jump adn make ticking noise. When there is no engine light present the car idles rough and acts like its going to die till you start driving then its fine. The issue with the brakes are when you to press them the pedal will depress all the way but its like it dont meet with the pad, this problem is intermittent as well. Obd2 codes have been p0641 p0017 p0651 p0573 current codes stored are p0340 p0300 p0341. I've had this car at the dealer and multiple shops on multiple occasions now without resolution. It's becoming more of a problem than anything especially when your on the interstate and it dies or coming up to a stop light/ sign, a car pulls out or an animal and your brakes fail to stop you! It is a very scary situation. The car does have high miles but I have not had any problems till december of 2017 mileage is 203,602 all maintenance is performed under recommended mileage.
