It started shutting off at a light for autostop.but when it would turn green it would intermittently just drop out of autostop without restarting. Then may start back up or maybe not, many time after restarting at the light it would died in the middle of the inspection. A parasitic draw kept killing the accessory 12 V battery replaced the 12 V battery but the problem continued. When the truck was running it would run flawlessly, before stalling. The code said to replace the auxiliary fluid pump. I had it a new auxiliary fluid pump installed. After this the vehicle wouldnt crank. They then worked through a service bulliten fixing a list of areas were the harness was chaffed and shorted. The truck has been out of commission the past 10 months and intermittently started twice during this time, it ran rough for 5 mins and died out at the first stop sign and wont crank again. Some times it will crank but not start.

Vehicle will jump forward when going into auto stop as if you are sitting at a light behind someone you would hit them, sometimes going down the road when going into hybrid mode it will stall and start jerking forward and steering locked up wouldn't turn witch would cause to run into someone
