- Some sellers may claim it s "new," but it could actually be a **refurbished or salvaged unit** with hidden issues.

3. **Limited Availability Outside Authorized Sources**

- While widely available from **Ford dealers and specialty auto parts stores**, finding a **verified OEM unit** can be challenging if you don t have access to official channels.

- If the original ECM was **flashed with a tune**, a replacement may need to be **reprogrammed** to avoid issues.
