NHTSA Complaint #11692640 — 2021 CHEVROLET SILVERADO 1500

The following is a list of persistent electrical failures in my vehicle, several of which present a significant safety risk. I have attempted to resolve the issues: •Emergency OnStar Button Failure: My vehicle's emergency OnStar buttons consistently fail to function when the ignition is off. This is a critical safety defect, as the system is designed to work on a backup battery during an emergency, such as a crash. The system only operates when the ignition is on. • Excessive and Dangerous Floor Hump Heat: Following a service visit on October 2, 2025, the front floor hump became excessively hot, melting personal items and posing a fire and burn risk. •Fabricated Safety Warnings: The vehicle's computer system repeatedly displays false and misleading messages. Examples include an incorrect "new brake pads detected" prompt and a "taking your eyes off the road" warning that does not apply to this vehicle. These phantom messages are distracting and can cause driver confusion. •Persistent Connectivity Failures: The vehicle experiences frequent and consistent failures with its Wi-Fi and GPS systems, indicating a potential electrical or software malfunction. Numerous resets attempted by the manufacturer's technical support have not resolved the issue. • Computer Display Anomaly: the Chevrolet symbol appeared in red on the computer screen when the truck was started. The vehicle has repeatedly experienced spontaneous changes to the radio station and the air conditioning switching from cold to hot without driver input. •Unusual Decompressing Sound: When the vehicle has been sitting for an extended period, an unusual decompressing sound can be heard coming from the rear underside whenever a door is opened. Date: Software updates on January 27, 2025 and October 2, 2025. Diagnostic Test performed on October 2, 2025 that failed to resolve the issues. The OnStar buttons only works when the vehicle is turned on. I do have photos and videos available to support your claim.
