Warning problems of the 2018 Tesla Model S

Received and error message, lane departure avoidance features unavailable and steering assist reduced simultaneously while driving between 65-75 mph. Steering will required extreme effort to turn. I was about 5 minutes from home exited the highway and took the backroads. Steering did require extreme effort. The following morning, car worked fine.

Shortly after an update in December, my 2018 Model S started getting alerts: driving visualization temporarily degraded, charge port sensor fault, autopilot cameras unavailable, automatic emergency braking unavailable, lane departure avoidance features unavailable, steering assist reduced. The map no longer knows where the car is located and cannot navigate or tell what the battery percentage will be at. All automatic features have stopped working. The service center claims the ecu needs to be replaced. It was upgrade to the autopilot/full self-driving ecu in 2020. I have read reports from dozens of other Tesla owners that this update also broke their ecu. I believe Tesla knows the new requirements for full self-driving to be safe and usable does not work with their current ecu. They want to charge me $1600 to replace the ecu. I cannot receive the recall ota update with my current ecu.
