Complaint Summary

FORWARD COLLISION AVOIDANCE: WARNINGS

Owner Narrative

Tesla released a new version of FSD: 2026.20.6.11 V14 Lite for my 2022 Model Y Long Range. I installed it overnight and the next morning, several systems become intermittent. The backup camera stopped working immediately, and FSD would drop out, with the message "Take control immediately". I would then lose traffic visualization and other advanced features. Eventually the system would recover and start the cycle all over again. Several times per drive. I took the car to the dealer and they diagnosed it as a failed HW3 computer. The cost to repair it was $2,939 out of pocket since my car was 2 months out of warranty. The car was 100% functional before the V14 Lite update. The dealership denied the problem was related to the update, but the internet now has numerous instances of this problem, and attribute it to the computer running much hotter under this new update, causing components to fail. Our update was installed while the car was in our garage at a temperature in the 70’sF and immediately caused the computer failure before the car even left the garage. I requested and was given the failed computer in case any independent investigation is needed
