The all around vehicle camera system fails on average every 6 months. As the dealership is far away in our area, I have to take a 1/2 day to full day off work to take it over. I believe we are now on the third replacement camera module, in need of a fourth that was just replaced less than two months ago. GM makes it unreasonable to deal with. They require you drive over to the dealership just so they can see the same problem is occuring and only then will order parts, requiring a second appointment. The problem is the same and this is just adding more time to the failing safety issue which is of major concern because we can't just drop in easily because we are in a remote area. It sometimes takes over a month for me to be able to schedule a time to go over there --- so I go many weeks with a failing camera system.

I am writing to report a serious safety concern involving my 2024 Chevrolet Silverado that resulted in a child being locked inside the vehicle with the key fob present inside the car. On March 25 2026, after parking and turning off the vehicle, I exited the driver’s seat with my key fob inside my purse, which remained in the front of the vehicle. I then walked around to remove my daughter from the back seat. During that time, she climbed into the front seat and pressed the interior door lock button, locking all doors. My daughter has autism and is not able to follow instructions or unlock the vehicle on command. As a result, she was locked inside the vehicle with the key fob present inside, and I was unable to gain access from the outside. The vehicle did not prevent the lock from engaging, nor did it allow me to open the door despite the key being inside the vehicle. This situation required emergency assistance (911) to safely remove her from the vehicle. I understand that many vehicles have “lockout prevention” features; however, in this case, the system did not account for a vulnerable occupant inside the vehicle. Allowing the vehicle to be locked from the interior while the key fob is inside—and without any external override—creates a significant child safety risk. I am requesting that Chevrolet review this design behavior as a potential safety issue, specifically: - Why the vehicle allows interior locking when a key fob is detected inside - Why there is no external override to unlock the vehicle when the key is present - Whether a software update or safety feature enhancement can address this risk This is not just a convenience issue—it is a safety hazard that can lead to dangerous outcomes, especially for children or individuals with disabilities. Please confirm receipt of this concern and advise whether this issue has been previously identified or is under review.

Formal complaint — outdated Android/Google Built-In security patch level on 2024 Chevy Silverado; potential cybersecurity defect and negligent maintenance by manufacturer. I am submitting a formal complaint regarding a critical cybersecurity and software maintenance defect in my 2024 Chevy Silverado. The vehicle runs Google Built-In / Android Automotive OS with an Android Security Patch Level of February 2024 (as displayed under Settings → About → Android version). As of this writing in December 2025, this patch level is nearly two years outdated, with no available over-the-air (OTA) updates and no clear communication from General Motors or Google regarding continued support or end-of-life status. This condition exposes the infotainment and telematics systems to known and documented vulnerabilities, representing both a cybersecurity defect and potential consumer safety. Description of the defect: The infotainment system reports “Android Security Patch Level: February 2024.” Attempts to check for updates return “Your system is up to date.” The system shows a red exclamation mark beside the patch level, indicating a fault condition or known update gap. Neither the dealer nor OnStar/Customer Support can apply an update manually or clarify the support cadence. This leaves the vehicle permanently exposed to Android-level vulnerabilities discovered and patched long after February 2024. Security and regulatory implications: The infotainment system runs a network-connected OS with Bluetooth, Wi-Fi, cellular, and vehicle bus access. Unpatched Android components are subject to hundreds of known CVEs since February 2024 — including privilege-escalation, RCE (remote code execution), and Bluetooth/Wi-Fi stack vulnerabilities. The U.S. NHTSA Cybersecurity Best Practices for the Safety of Modern Vehicles (2022 update) and ISO/SAE 21434 require that manufacturers maintain timely security updates for all connected vehicle systems.

Formal complaint — persistent, non-disableable Bluetooth transmitter in [2024 Chevy Silverado] / privacy & safety risk; request for remediation and recall assessment I am writing to file a formal complaint regarding a safety and privacy defect in the infotainment/telematics system of my vehicle, a The unit runs Google Built-In / Android Automotive OS. This complaint documents technical evidence that the vehicle’s Bluetooth radio broadcasts a persistent, non-randomized MAC address and cannot be completely disabled via any user-accessible control. I request immediate remediation, a formal security assessment, and confirmation whether this condition will be remediated by firmware/OTA update or recall. Summary of the issue The infotainment unit’s Bluetooth adapter emits BLE advertisements that expose a static, permanent MAC address i.e ([AA:BB:CC:DD:EE:FF]) that does not change across power cycles and is visible to passive scanners while the vehicle is parked and otherwise idle. The vehicle provides no persistent user control to turn off the Bluetooth radio; menus do not disable the hardware radio. Attempts to disable Bluetooth via the system settings are ineffective. The static MAC and inability to disable the radio create an ongoing privacy and tracking risk: third parties can uniquely identify and track the vehicle across time and locations by logging the broadcasted identifier. This configuration is inconsistent with current industry cybersecurity & privacy guidance that recommends minimizing exposed identifiers, providing user control to disable wireless interfaces, and implementing randomization of wireless addresses when possible. The static MAC plus non-disableable radio constitutes a persistent, unique identifier broadcast in public spaces. This defeats reasonable efforts by consumers to limit tracking and to control their privacy.

On [XXX], I [XXX] ) experienced the following issues with my new 2024, Chevrolet Silverado - 1500: • Front Windshield Wiper Washer Fluid not spraying/dispensing. • No messages or symbols displayed on the Driver Information Center dashboard indicating Windshield Wiper Washer Fluid Reservoir low/empty. • Inspected the reservoir that holds the fluid and did not observe low/empty. • Took it to the GM dealer 4 times and they were unable to repair. My vehicle has a recurring defect with the windshield washer system where the washer fluid does not dispense when activated. This issue occurred on a new vehicle and has persisted despite service attempts. When the washer fluid fails to spray, I am unable to clear dirt, dust, road debris, or moisture from the windshield while driving. This significantly reduces forward visibility, especially at freeway speeds or in conditions where debris from other vehicles hits the windshield. The inability to clear the windshield immediately creates a safety hazard because it can obstruct the driver’s line of sight and increase the risk of a collision. This issue is not cosmetic, it directly affects safe operation of the vehicle and the driver’s ability to maintain visibility during normal driving conditions. I am reporting this because the defect is ongoing and may affect other vehicles of the same model. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
