Please also check out the statistics and reliability analysis of the 2012 Chevrolet Malibu based on all problems reported for the 2012 Malibu.
Vehicle was in motion at about 60 mph on a highway and the rpms dropped drastically, the anti skid indicator light came on, the vehicle lost power temporarilly. I pulled over and slowed down and the car returned to normal. Same evening vehicle was in motion about 55 mph on a highway when there was a loss of power, steering got sluggish,all indicatorlights on dash blinked on and off engine light came on and stayed on, anti skid indicator light came on, was knocking in motor and car would not accelerate over 20 mph. Completed a diagnosis of the vehicle and a code p0068 was noted by diagnostics. P0068 the engine and transmission system is not performing as expected. An issue has been detected in the throttle control system that connects the accelerator pedal with the throttle and integrates features such as cruise control, traction control, stability control, and pre-crash systems. If the check engine light is flashing, a misfire condition has been detected. A misfire increases vehicle emissions and could damage the emission control system on the vehicle. Please reduce vehicle speed, avoid hard accelerations, avoid steep uphill grades, and reduce any cargo loads such as a trailer. If the vehicle is continually driven with the check engine light on, the emission controls might not work as well, the vehicle fuel economy might not be as good, and the engine might not run as smoothly. This could lead to future repairs.
