We bought a 2011 malibu used from a private party. It ran great, no dash lights, no weird noises or hesitation, everything was good. Then a couple weeks later it started up, drove 100 yards and stalled. We couldnt get it restarted so we had it towed and our mechanic found a problem with the battery connection, so he replaced the connector. Fired right up and all was good. Then 3 days later while leaving for work it stalled out before making it to the end of the street. He covered the tow this time and wound up replacing mass airflow. Again all was well and the car drove great...for 2 weeks. Then one day, pulling out of parking lot at work it stalled out again and would not start. It has been at the shop for almost a month now and the mechanic is stumped. There are no codes. He checked all the fuses, camshaft solenoid and sensors, made sure the maf he replaced wasnt a bad part, idle air control, fuel pump, fuel pressure all good. It just starts and then immediately dies. It's also crazy that it was repaired and it worked but then the issue returned.. twice.
Any ideas? I dont know if he's just frustrated and needs some fresh ideas or what, but I gotta figure out the fate of this vehicle soon.

 

what engine? the info i give may be incorrrect if the engine is different
no power train codes but are there any theft codes?

the 2.4 l engine...they have had issues with camshaft sensors causing this. disconnect one cam sensor and try to start...if no change reconnect and disconnect the other cam sensor...if it starts...check the sensor 5v ref wire...if the voltage is pulled low as the sensor is plugged in...replace that sensor.

If this fixes the car...inform your mechanic he needs to subscribe to identifix. It is a repair website that offers solutions to problems that don't conform to conventional testing.

 

I have the exact same issue with my 2012 Malibu 3.6 - Did you ever get this fixed? The car has been in the shop for a long time and no one can figure it out.
