At a Tesla Service Center this typically costs **$0 - $150 (Diagnosis only if the USB port is faulty)**. An independent shop charges about **$0 - $100 (Rarely needed)**, and doing it yourself costs **$15 - $60 (High-endurance USB drive or small SSD)** — potential savings of **60% - 100%**. DIY difficulty: easy (10 - 20 Minutes). ![Dashcam / Sentry Mode USB Drive Not Recognized](https://evfixguide.com/assets/images/service-mode-screen.jpg) ## Symptoms - Dashcam icon shows an error or 'unavailable' message on the touchscreen - Sentry Mode events are missing or videos are corrupted - Recordings stop after working fine for weeks or months ## Repair cost: Tesla vs independent shop vs DIY | Option | Typical cost (USD) | | --- | --- | | Tesla Service Center | $0 - $150 (Diagnosis only if the USB port is faulty) | | Independent shop | $0 - $100 (Rarely needed) | | DIY | $15 - $60 (High-endurance USB drive or small SSD) | | Potential savings | 60% - 100% | Ranges are US estimates compiled from owner reports and shop quotes; prices vary by region, model year and parts availability.

If no USB device is recognized in any port, a Tesla Service or independent shop visit may be needed to check the USB hub or wiring. [Get matched with an independent shop →](https://evfixguide.com/?shop=dashcam-usb-not-working#find-shop-section) ## How to fix it yourself (easy, 10 - 20 Minutes) Use a quality high-endurance USB drive or SSD, format it from the car, and plug it into the correct port. No tools are needed. ### Tools you need - High-endurance USB flash drive or portable SSD (64 GB or larger recommended) - Computer (optional, to back up existing clips before formatting) ### Steps 1. Back up any clips you want to keep, since formatting erases the drive. 2. Plug the drive into the car's front USB port intended for data. On many newer Model 3/Y vehicles this is the port in the glovebox; other ports may be charging-only. 3. Go to Controls > Safety > Format USB Device. The car formats the drive (exFAT) and creates the TeslaCam folder automatically. 4. If formatting on a computer instead, use exFAT or FAT32 and create a folder named TeslaCam at the root of the drive. 5. Wait for the Dashcam icon to show it is recording, then test by saving a clip. 6. If the drive keeps failing, replace it. Cheap flash drives wear out from constant recording. **Pro tip:** Dashcam writes video continuously, so standard thumb drives often fail within months. High-endurance drives or SSDs designed for constant writing last much longer. ## Frequently asked questions ### How much does it cost to fix a dashcam USB that isn’t recognized on a Tesla?
