I have been using the Dashcam facility of Model 3 for a while. I have a Fat32 formatted 128GB USB drive. Initially i used to check the recording every other day to confirm if the events of the day like drive to and from work, time in the parking lot is being recorded properly. I then forgot about checking the video for a while till last week when i found out someone had dinged my car in the Parking lot at work. When i got home that day and inspected the drive (it was about 28G used) i noticed that the recording has not been done for the Drive into work and for the time the car was parked for that day. It had recorded the drive home. When i checked for last 7 days i saw it hadn't recorded for few days (weekdays when i use the car) and for days where there was some recording it was incomplete or sometimes it wouldn't open the file. I even tried enabling Sentry mode the next day and i saw the same behavior. I open a case with Tesla 3 support (Sunnyvale), met with a Service advisor who told me that he would need the logs to be analyzed by some specialist and they would let me know why the recording has been irregular and messed up. Its been few days now and i havent heard back from them. I have called up few times, left messages but no response.
Please let me know if you have faced this issue or if you know of any solution here?
I formatted the USB drive yesterday and drove the car into work today. When i inspected the drive i see that the video for the morning drive and most of the parking timeframe is not available. The last 1 hour in parking lot and the drive home was available.
