Per the Tesla service team, there is a defect in the car computer which causes intermittent signal of the backup camera, failure of automatic emergency braking, and also Autopilot unavailability in a 2021 Tesla Model Y with less than 40k miles on it. This issue only occurred after a software update and affects key safety features such as blind spot warning proximity warnings. The Tesla service team said the only way to solve it was to replace the entire car computer and charged us $2,583 for their own product defect. The car did issue alerts to us saying that Autopilot and automatic emergency braking were unavailable, but did not detect issues with intermittent camera signal.
