2024 CHEVROLET SILVERADO EV Electrical System Problems

While in traffic over 45 miles per hour, the vehicle placed itself into a hazard mode due to the electric vehicle propulsion system. This happened so fast and the deceleration rate was so quick that it risked a rear end collision. This is the second time this has happened and both were following a heavy rain storm. I drove through a modest puddle that did not even submerge half of the tire wall making contact with the road and did so slowly. Less than five miles later, the vehicle goes into what my service advisor calls "limp mode." I have asked General Motors to give me an even exchange or, in lieu of the fear this vehicle gave me, an upgrade to a Cadillac Escalade IQ.

The backup camera stopped working around July 1. I took the vehicle to the dealer and the dealer could not fix the problem. The dealer says GM is aware that some vehicles have their backup camera stop working and is working on a software fix. Backup cameras have been a required safety item on all cars sold in the US since 2018. An inoperable camera thus is a safety risk. There are no warning lights or other messages.

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...

The rear door sensors do not function, doors are always indicated as being closed, even if they are open. The car gives no warning if door open and vehicle put into drive. Also with walk away lock the vehicle can lock while rear door is in the open state resulting in accidentally locking a occupant in the vehicle. The walk away locked engaged while I was at the rear of the vehicle unloading my dog from the back seats.

Vehicle fails to determine if either passenger or driver rear doors are open. The vehicle is missing some functionality where the door can be opened and vehicle can be driven. My child can open the door and there will be no warning about the door being open. The interior lights do not come on when any of rear doors are open.

Rear door sensors do not work. No dash light or dome light to indicate if a door is open or adjar. If a child is in the back seat doors could be left open and the driver would not know.

When the rear doors are opened on the truck, the interior lights do not come on which is a hassle when securing an infant in a car seat. Further to this, the door ajar symbol on the dash does not come on for either rear door, it does come on for the front doors. I talked to GM about this and they said that since it's a WT model with the base lighting there are no rear door lights or sensors. I found another person with the same model truck where there dealer found the same problem but fixed it.

The rear passenger door sensors are not working on my vehicle as delivered from the factory/dealer. Upon opening the rear doors, there is no indication on the instrument panel/dome illumination as is present for the front passenger doors. With 4 independent doors it would appear to be a possible safety concern as the rear doors could unknowingly be open while driving. This issue has been discussed by several Silverado EV WT owners at the forum (linked below) and at least one dealer has diagnosed the issue as a missing ground wire on the door latch/sensor as documented in the service write up attached that was shared via the forum. However, other dealers are refusing to correct the issue as has been the case with my dealer thus far.

Vehicle does not indicate when rear doors are ajar or not properly latched. Vehicle information center shows when front doors or frunk is open. Results are either door swinging open when not properly latched or in my case, as the vehicle does not know that the doors are open, immediately locking the vehicle with the fob in my bag on the rear seat. I disabled the walk away locking feature for now as I only have 30 days of remote services with the vehicle to unlock vehicle from my phone. Vehicle is currently at Chevy dealer for troubleshooting. Quick search and communication with other owners indicates this is not an isolated incident.
