2024 Chevrolet Silverado EV

On XXX, at midday, in the Haggen parking lot in [XXX], I unlocked the passenger door with the silver exterior door button. At that moment the side-view camera display glitched, and afterwards the exterior door buttons stopped working. The key fob and the interior door buttons still worked. Restarting the infotainment system did not fix it, and the passive-unlock setting was not the cause. After I left the truck locked and asleep for about 20 minutes, the buttons and cameras both worked again. I use the side cameras for lane centering while driving.

I own a 2024 Chevrolet Silverado EV WT equipped with the OEM soft tonneau cover. The original cover and its warranty replacement have both failed in the same way. The cover material appears to shrink over time so that the side flaps will no longer reach and stay attached to the Velcro along the bed rails. At highway speeds the cover flaps and “balloons” upward, and the Velcro strips will not stay connected even when properly installed and tightened. The dealer has already replaced the cover once under warranty, but the replacement has the same problems. This suggests a design or materials defect, not a one‑time bad part or installation error. In my opinion, the flapping and ballooning could allow the cover to come loose or detach at speed, which could create a road hazard for other drivers. I am asking NHTSA to track these failures and evaluate whether the OEM soft tonneau cover on the Silverado EV presents a safety risk similar to prior GM tonneau cover issues where covers detached while driving.

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.

When charging my Silverado EV at Level 3 DC Fast chargers it is not charging at the same Voltage / Power as it has been in the past at the same stations (roughly half the power). I have taken it to the service center for diagnostics but they were unable to isolate the component that caused this problem, only reproduce the problem. Further details below. What component or system failed or malfunctioned, and is it available for inspection upon request? - The Level 3 DC high voltage charging is not charging at the same voltage as a comparable Silverado EV. (Pictures attached) - I can demonstrate the problem with my car on request, I have attached pictures of a new Silverado EV charging as well. How was your safety or the safety of others put at risk? - I would not consider it safe for level 3 DC charging which involves high current and high voltage to not be working as designed. It is also unsafe to not have any warning lights indicating that the charging is not working as designed. Has the problem been reproduced or confirmed by a dealer or independent service center? Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - The problem has been reproduced and confirmed by John Heister Chevrolet of Fuquay Varina NC. They were unable to isolate a component that is causing the issue and have sent log files of the car to the engineers at Chevy to further diagnose this issue. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - There are no warning lights / messages indicating that there is a problem even now. Only the symptom of not charging at the expected Voltage / Power level. - Symptoms were first observed by me on December 16, 2026

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!

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.
