Update Issues

The recent update has created two error codes for CAN 1 and CAN 2 sensor timeout. The Ethanol sensor value is at 0%. Following a reflash the car generated a Power Management Fault and Incorrect Shutdown Error. The Ethanol sensor value went to 0 again. No issues with car or software since last release. Why do updates get pushed automatically? I’d rather update after everyone exposes bugs and they are resolved. Clearly MHD tests code in production.
