My 5-month-old blue Model 3 was just scraped by a white pickup in the post office parking lot. My wife was inside at the time and I was home. When she came out 2 people shouted that a white pickup had scraped the side of my car and then took off. They didn't get the license # but she didn't despair. We have Sentry Mode! When she got in the car she saw the red exclamation mark in the upper right which, when you press it, says the USB speed is too slow so Sentry Mode had stopped working. When I checked the flash drive I found that it had recorded the first minute of her drive to the post office but nothing after that. The post office doesn't have video monitors in the parking lot so we're screwed. This is the third USB drive we've tried with Sentry Mode. The first was the 64 GB Sundisk, which is recommended in articles for this purpose. It worked fine for 2 months, then got the "too slow" message. I read all the forums about this problem and have since tried two others. The latest was a Sundisk USB 2 drive. It has worked for a month, has recorded many Sentry mode incidents with no problem (one from yesterday), and now failed 15 minutes before the accident. Both doors on the left side are dented and have a long white scrape mark. I have $2,500 collision deductible so that'll be out of pocket. Don't get me wrong. I love my Tesla and expect to have "growing pain" problems from time to time but this is getting old. How do I fix this USB problem once and for all??
