2024 Chevrolet Silverado Ev

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 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 does 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: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.
