There is apparently a known issue on the WT ‘Work Truck’ trim of the Silverado EV trucks where the factory wiring harness was assembled incorrectly. This prevents the truck from knowing when the rear doors are open vs closed. If only one (or even both) rear doors are open, all the doors may automatically lock (depending on auto-locking settings), potentially locking the driver out of the vehicle. As a first responder I immediately recognize this as a significant child safety issue: if a parent were to get out to check on their child in the back seat, finish what they were doing, then close the doors to get back in the front, they could find themselves locked out with their child locked inside. Because this would also mean the truck would be shut down, the climate controls would be turned off when this happens, and could easily result in heat injury or death of a child. This door issue also causes a safety issue as the dome lights do not come on when the rear doors are opened, and a door could potentially be partially or even wide open without the truck alerting the driver. The dash clearly shows and identifies the front driver and front passenger door open indicators, but ds not show either of the rear doors. I have not taken my truck into the dealer for correction of this issue yet, but I have confirmed this is an issue with multiple other Silverado EV drivers who have the WT trim (both 3WT and 4WT packages). While I will be working with GM to address the issue on my vehicle, I feel the potential risks of this issue are significant enough that the NHTSA should intervene for all affected vehicles. To save a little time, here is a forum post on the matter. Post #16 has a service description from a Chevrolet tech about this issue on another truck: https://www.silveradvforum.com/threads/issue-with-rear-door-sensors.1514/
