Troubleshooting Unavailable Cruise Control on Your 2021 MSP
Cruise Control Unavailable
It can be frustrating when your car’s cruise control feature stops working. It is especially annoying if the problem occurs after you have just bought a new vehicle. This happened to one driver who purchased a 2021 MSP and drove it home with no issues, but then found that their cruise control was unavailable the next day.
The driver rebooted the car and disabled sentry mode, opened/closed all doors and frunk/trunk, but this did not solve the issue. The driver then replaced the USB stick inside the glove box with a different one and formatted the new one using the UI. This also failed to fix the issue.
When they started up the car, FSD visuals were back, but within 3 blocks it had disabled itself again. Dashcam recordings showed that all cameras were clean and crystal clear. The driver reset camera calibration, drove 15 miles, but still could not get it to work.
It appears as though something may be out of wack, and hopefully this is all it is as further troubleshooting may be required. If this does not fix the issue, contacting customer service or taking your car in for repair may be necessary.
In conclusion, if your cruise control suddenly becomes unavailable on your 2021 MSP, try replacing and formatting the USB stick, resetting camera calibration, and driving around for a while before contacting customer service or taking it in for repair.Hopefully, this will solve the issue.
