As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 141, "Minimum Sound Requirements for Hybrid and Electric Vehicles."

    Risk: Pedestrians may be unaware of an approaching vehicle if the PWS sounds are obscured, increasing the risk of a crash.

    Remedy: Tesla will perform an over-the-air (OTA) software update that will disable the Boombox functionality when the vehicle is in Drive, Neutral and Reverse modes, including Summon and Smart Summon, free of charge.

    Car was sitting at a red light while in Full Self Driving (supervised). The screen showed at least four red lights. Suddenly the car started to move forward while the lights were still red. I was able to stop it from going further. This has happened before and I reported it then. If I had not had my foot near the brake pedal the car might have just run through the light.

    On XXX at approximately 5:00 PM, I was driving my 2020 Tesla Model 3 on [XXX] from [XXX] toward [XXX], with Tesla FSD engaged.

    My Tesla Model 3 was brought to Tesla Princeton Service Center on February 27, 2025 for a 12V battery replacement.

Upon picking up the vehicle, the rear backup camera, blind spot cameras, navigation system,…

    When adaptive cruise control is enabled (Autopilot, not equipped with Full Self Driving) car will sometimes brake hard as if there is an obstacle ahead, with the words "Curve Assist Active" flashing on the screen. Seems to happen most often on state highways, vs interstate. In one case last night car slowed from 65mph to 30mph, on a straight road, with no object ahead. Thankfully no cars were immediately behind or I would have been rear-ended. Happened 4 times in 500 miles…
