2013 CHEVROLET MALIBU ECO with 38548.0 miles

Around the time i bought the car, on 11/30/12 at 5812 miles, unknown to me the car had a concern of loss of battery charge which called for an inspection of the generator control module. So a gen control module performance test per recall was performed. In may of 2013, i stopped at red traffic light and the engine was idling, when i proceeded to accelerate by placing my foot on the gas pedal at the green light, the vehicle shut off on me. This had nothing to do with the automatic shut-off that conserves energy. On 6/24/13 at 14006 miles, i tried to get them to do a diagnostics and i don't think they did a diagnostics even though i was still under bumper-to-bumper and powertrain warranty. They suggested a test drive with a mechanic foreman to see if the issue would present itself again. The issue did not occur again. In july of 2013, i then complained that the car had poor engine acceleration entering onto a highway and took it in for service at 14810 miles. They did a r&r ecm recalibrate controller program. On july 26, 2014, i drove earlier in the day for quite a few hours through the city and a little on the highway. I accelerated once on the highway at which the issue of acceleration presented itself again. At 38,548 miles, the following messages was shown on my dashboard: 1. Battery service needed 2. Power steering service needed i then called onstar and i asked them to do a diagnostics and they gave me the following messages: 3. Engine control module cruise control system not performing as expected. (P155A) 4. Powertrain system has detected malfunction related to cruise control system. Cruise control disabled. (C0800) 5. Powertrain system has detected malfunction related to transmission. The check engine light will not illuminate. Vehicle performance and shift behavior may be affected. Top shift feature will be disabled if equipped. (P0826) *js

2012 CHEVROLET CRUZE with 64829.0 miles

On the first occurrence the lights on the radio display began to flicker and then all electrical power to the dashboard. The electrical came back on and the dash display depicted the warning message check stabilitrak. I took it to the dealership where i purchased the car and they said that high voltage codes C0800, 07 and high voltage history showed up on the scope and there were no issues. The second time the lights on the radio display began to flicker and then all electrical power to the dashboard, airbags and the electrically assisted power steering went out, while on a very steep mountain road and i had no control over the vehicle. The electrical came back on and the dash display depicted the warning message check stabilitrak. I took it to a different dealership and the dash flickering occurred with the service person in the car driving but nothing showed up when the mechanic was trying to fix it so they said there was nothing they could do. Two days later while my daughter was driving she lost power steering and the same issues with the dash and was involved in an accident, thank god her baby was not in the car. Please help!....Updated 07/31/14 *bf
