2024 Chevrolet Silverado EV Problems

See attached document for complaint.

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.

On 1/20/26, we purchased a ‘24 Chevy Silverado EV from a Chevrolet dealership. 2 days later, on 1/22/26, while my husband was driving on the interstate, the tonneau cover partially detached and flew backwards lifting upwards and flapping violently. One of the metal crossbars detached completely from the tonneau cover and flew off the truck, and a second crossbar began to tear away. The cover was flapping forcefully which created a highly unstable and dangerous condition. My husband pulled over on the side of the interstate to remove the tonneau cover to prevent it from fully detaching. He placed the cover into the truck bed. This incident occurred suddenly, with no warning. This was a near-miss incident with potentially catastrophic consequences. If the tonneau cover had fully detached, it could have become airborne and struck another vehicle. The crossbar that flew off, could have struck another vehicle, easily penetrating a windshield, causing another driver to lose control, or result in a multi-vehicle collision. The risk of serious injury or fatality was significant. The next day, on 1/23/26, we took the truck and damaged tonneau cover to our local Chevrolet dealership for inspection. The service manager visually inspected the cover and documented the failure. We scheduled an appointment for repair at their soonest availability, 2/4/26. We will not feel comfortable using a new cover unless a modification is made to adequately secure the cover to prevent this from occurring again. We also called the Chevrolet dealership where we purchased the vehicle from and spoke with the general manager to let them know what happened, as they have sold close to 100 of these Chevy Silverado EV’s. They said this has happened to others and they speculate that GM is already aware of this concern. We urge the NHTSA and GM to take immediate action. Please open an investigation and issue a recall before someone is seriously injured or killed. Thank you NHTSA!

The contact owns a 2024 Chevrolet Silverado EV. The contact stated that while operating the vehicle in sub-zero temperatures, the HVAC unit failed to blow hot air through the vents. During the failur,e the contact was unable to defrost the windows. The vehicle was taken to the local dealer who determined that the heater control module was inoperable and needed to be replaced. The vehicle was not repaired. The contact was informed that the heater control module part was on a national back order and currently not available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 13,000.

The exterior passenger side 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 (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 any roadway or even maneuvering while parking. It is impossible to adjust the flat glass mirror to bring a smaller car to the right side of this truck into the driver's field of view, and at the same time, approaching traffic from the right rear. This is particularly dangerous when needing to make a quick "glance and maneuver". GM Parts has advised there is no alternative replacement mirror for this truck. Replacing the flat glass mirror on the passenger side with the commonly used passenger convex mirror glass would correct this hazardous situation.

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)

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.

The contact owned a 2024 Chevrolet Silverado EV. The contact stated that when idle, the vehicle would hesitate before accelerating. Continuing to drive at approximately 55 MPH, the accelerator was released, and the vehicle continued to accelerate. The vehicle veered off the road, where the vehicle flipped a total of 5 times before coming to a stop. The contact received injuries to their back, whipflash, and a contusion of the stomach. Medical treatment was needed and had been ongoing. The vehicle was towed and totaled. A police report was filed. The manufacturer was not informed of the failure. The failure mileage was unknown.

On multiple occasion parking sensors activate for no reason. Emergency braking occurred while backing as well as while driving for no reason at all. High possibility of a crash occurring. 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.

I am 6'2" tall. The shoulder straps on both the drivers and passenger side do not adjust up far enough to protect me in the event of a crash. The straps slip down below my shoulder. This is due to the fact that the WT model does not have power seats, so I am unable to lower my seating position to a safe level. If the seat could be lowered, the shoulder straps would sit properly above my shoulder. In the event of a crash the shoulder strap will be totally useless.

Under heavy acceleration the vehicle swerves from lane to lane and the operator is unable to counter the steering. The behavior continues until the acceleration is halted. The vehicle was grounded due to it being deemed unsafe by the originating dealership technician and repairs were attempted but were unsuccessful. The dealership had another vehicle like mine in inventory so they tested that one and found the same erratic behavior but rather than deeming it to be a problem they declared the steering issue it to be normal for that model. This is section 4 of the attached dealership service report.
