Owner Narrative

I reporting a potential safety-related defect involving my 2023 Tesla Model Y Performance. Since shortly after purchasing the vehicle in April 2026, it has repeatedly been unable to successfully install Tesla software updates. The updates download, but the installation repeatedly fails. I have attempted installation multiple times under appropriate conditions, including adequate battery charge, stable Wi-Fi, vehicle reboot, removal of USB devices, and installation directly from the vehicle touchscreen. The failures continue. Tesla evaluated the vehicle and documented the failed software installation. Tesla also identified a possible issue involving the HW3 car computer and prepared an estimate of approximately $3,000 that included replacement of the vehicle computer, diagnostic work, and labor. I am concerned because Tesla vehicles rely extensively on their onboard computers and software for vehicle operation, safety systems, driver-assistance functions, security updates, bug fixes, and manufacturer-issued corrections. Because this vehicle cannot successfully install software updates, I am concerned it may be unable to receive safety-related corrections or updates that other vehicles are receiving. This is not simply an infotainment issue. The failure appears to involve the vehicle computer itself and has continued despite repeated troubleshooting and Tesla service involvement. I believe NHTSA should evaluate whether defective HW3 computers or related electronic systems can cause repeated update-installation failures and potentially prevent affected Tesla vehicles from receiving safety-related software updates or recall remedies.
