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.…

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 do…

Observation: "While operating the vehicle in Reverse (R) with the One-Pedal Driving (OPD) mode enabled, the expected aggressive regenerative braking deceleration is disabled or significantly reduced compared to when driving forward in Drive (D). Safety Concern: "This creates an unexpected driving experience where the car continues to coast/accelerate without input when the accelerator is released, requiring the driver to use the traditional friction brake pedal to stop the vehicle. This goes against the driver's established muscle memory and e…

The Passenger Side door mirror is manufactured with flat glass and Not Convex glass. The flat glass field of view is not nearly wide enough for this large truck. This flat glass combined with the width of the truck (distance from the driver's head/eyes to the passenger door mirror), height and length of the truck creates a substantial risk for an accident while traveling on the roadway, highway or even maneuvering while parking. It is impossible to adjust the flat glass mirror to indicate a smaller car to the right side of this truck, and at…

Vehicle was taken to Chevy dealership on 4/23 this issue has been confirmed and replacement parts on order. Under bumper to bumper warranty.
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.

This can blind other drivers and possibly case a crash. The other Dangerous safety feature on the vehicle is the Automatic Emergency Braking. The AEB feature when crawling behind another vehicle in bumber to bumper traffic will randomly just slam on the brakes unnecessarily which could cause a rear end collision. When this happens, There is no need for emerge…

Gm refuses to repair or replace. Gm stated dealer says vehicle has completed repairs and vehicle ready for pickup. Dealer has not repaired or replaced any items or parts.

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 …
The vehicle experienced repeated high-voltage system warnings and battery conditioning system failures. On multiple occasions the “Service High Voltage System” message appeared along with codes P0530 and P1C26 related to the lithium-ion battery conditioning system that controls heating and cooling of the high-voltage battery pack. A critical U3578 code triggered an urgent OnStar alert requiring immediate service. The high-voltage fault was linked to an overcharged HVAC system that caused the A/C compressor to fail. This led to a full HVAC syste…
