Vehicle bought used in March 2019 with 96000 miles roughly recurring p0011 and p0010 codes after several repair attempts. Stealership will not return calls or attempts to meet about this and a list of other issues that have not been fixed on agreement. Car shuts off in traffic at times and has shut off while crossing highway and was almost T boned with my kids in the car. I have replaced both cam actuators twice to date and still nothing. May be a PCM issue but unable to test without GM equipment.
