During phone calls, the system would start making sparking noises and stall the calls. While navigation was input parts of the screen would disappear. While backing up, the rear cameras would freeze and stall. The rear camera freezing had caused us to get into an accident, and caused us to have 4 near misses. When I was trying to download the latest software release, the software download froze and never downloaded. I started to drive to the Tesla dealership and as I was doing so, the screen picture of my vehicle disappeared along with the gear shift indicator, the surrounding cameras failed. Then when I put on my turn signal, the sound disappeared. Then eventually the indicator disappeared. The entire screen froze with no information, and then went black while I was driving to the Tesla dealership. …
To whom it may concern, I would love some help with an issue I'm having with Tesla. I purchased my 2020 Model Y used from Tesla and the car was and is still under bumper-to-bumper warranty. I've had dozens of issues with the built-in dashcam and sentry modes that have stemmed from an update Tesla made, which has also resulted in my USB drives causing repeated errors. And while the USB drive error may not seem bad, it causes issues with the sentry mode and dashcam where they don't work and these features are some of the main reasons that I purchased the car, also making the car valuable to me and my family. Despite this, even though the car is still under warranty, Tesla Service in Sacramento is trying to charge me for my ninth service center visit for this same issue. …
On [redacted], I identified a severe and unacceptable loss of driving range in my 2020 Tesla Model Y (VIN: [redacted] , mileage: 59,127 miles). The vehicle now shows only ~180 miles of range at 100% charge, compared to the original advertised 316 miles - representing a ~43% loss of range. This degradation is far outside normal industry standards for EV battery health. This loss of range significantly impacts vehicle safety, as trip planning becomes unreliable and there is a heightened risk of being stranded on highways or in unsafe locations without charging availability. This could endanger both myself and other drivers, especially in rural areas or during extreme weather conditions. The issue has been repeatedly reported to Tesla, but they have failed to provide a technical explanation, battery replacement, or corrective action. …
Observed intermittent center display/infotainment computer (MCU) crashes/reboots where the center display becomes blank and then restarts. In recorded events, when reverse was selected during an MCU reboot interval, the rearview camera image did not display until the reboot completed. Recorded rear camera unavailability during reverse was approximately 10-17 seconds. MCU crash/reboot behavior was observed to be repeatable, including predictable occurrence while the vehicle was in the built-in Service Mode. After a factory reset, repeated/double boot behavior was also observed. Additional observations: - With the turn signal activated, light leakage was observed in the side repeater camera image (glare/bloom present in the camera view). - With each windshield wiper sweep, the forward camera image was observed to briefly flicker to a purple/green distorted state and then return to normal. …
On June 17, 2026, I experienced a severe and life-threatening entrapment inside my 2020 Tesla Model Y. The incident occurred immediately after I finished charging the vehicle for approximately two hours at a charging station under direct sunlight, which left the car extremely hot. After charging, I drove a short distance, parked, and left the vehicle for approximately 20 minutes. Upon my return, my card key failed to unlock the vehicle. After contacting my wife for assistance, I was briefly able to open the door, but I became securely locked inside the cabin as soon as the door closed. The 12V battery had completely failed without any advanced warning or vehicle alarm. All power was lost. The windows were fully rolled up, the climate control stopped, and there was no airflow. The cabin temperature was rapidly rising due to the earlier sun exposure. …
I ordered a used Tesla Model Y (VIN [redacted] ) on [redacted]. At the time of purchase, the car had 31,540 miles and was picked up from the Stockton, CA location on [redacted]. Since then, the car has performed pretty well, however I've recently experienced a slew of issues with the dashcam function of the vehicle. I've taken the vehicle into Tesla Service on two separate occasions, however they were unable to fix the problem and now I'm hesitant to drive the vehicle. One of the primary reasons I chose a Tesla Model Y was for the safety and security of having a car with a built-in dashcam and now that works infrequently. I've taken the vehicle into Tesla twice for this issue and they have been unable to fix nor offer a solution for this issue. …
