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.

   The wiring in my trunk harness was severed due to the repeated opening and closing of my trunk. This caused my reverse lights to fail and my trunk latch to stop working. This issue is part of a known recall: Campaign 21V-00D. Tesla attempted to fix the issue in 2023 but the poor repair did not work. I took my Tesla to the dealer and they refused to remedy the issue unless I would pay $1300. I persuaded them to lower the feet to $300 but still feel that I should not pay…

   The screen (which controls all functions of the vehicle) starts to go haywire. It's almost like there is a phantom touching the screen and pressing buttons. The screen will start zooming in and out - changing your navigation destination. The air controls will turn on full blast and then you are unable to shut them off because the screen will not respond. It becomes a giant distraction to the driver (imagine a screen that large malfunctioning) and tesla does not think this is…

   My Tesla Model 3 was brought to Tesla Princeton Service Center on February 27, 2025 for a 12V battery replacement. During the service visit, Tesla also replaced the rear glass, citing the rear defroster as the root cause of the battery drain — a repair that was added without prior discussion and increased the total invoice from an original estimate of $180 to a final charge of $1,730. Upon picking up the vehicle, the rear backup camera, blind spot cameras, navigation system,…

    My Motor Control Unit failed. No reason given by Tesla Service Center. It simply just died. They cannot find a reason, and they also said I didn't do anything to cause the MCU to fail. Service Center agrees this is a rare event. Likely got a really faulty MCU to start with. I bought my car in 2020, so just over 4 years later my MCU died.

    I am still waiting for tesla to make this repair. I have contacted a service center several times and tried to make an appointment once. Tesla cancelled the appointment and keeps telling me they have not received the parts to make the repair. It has been over a year and a half since tesla announced the recall and it has failed to repair my car. My understanding is that the harness can short out and cause a fire.
