19 Silverado TrailBoss V6: Several times now the truck stalled out when in park and idling. I try to restart and it turns over but won't start, take the key out and try again a couple minutes later and it works but the check engine light is on. Prior to this starting, last week while driving 60mph on highway the truck shuddered/shook a few times and the check engine light came on. OBD reads out P16AF & P16A7 as the error codes. Dealership said they ordered a new part...anyone having issues like this? Also, still no fix on the backup camera glitching out. Someone is gonna get hurt and GM has been made aware and I filed it with NHTSA. No fix yet...
I just purchased a 2013 2500hd with the 6.0 from a dealership last week with 84k miles on it. Tonight I started it and the service traction control light came on with the message on the info center. That's weird but then the doors started locking and unlocking themselves, the gauges kept going on and off, the engine would surge under any throttle so bad I couldn't drive faster than 55mph and the CEL came on. I took a video of what it is doing. The engine codes I got were pending and they are P105C P2544 Has anyone dealt with anything like this before?
