The steering wheel is locking up. First while parked and attempting to leave. It ds eventually unlock and appears to not have what i would refer to as power steering. While driving it appears to not have power steering and the steering periodically locks up which i would immediately brake a have to repeatedly yank hard on wheel until it unlocks at this point as of the moment of this writing the steering wheel is completely locks up and cannot be yank out of lock at all. I have a video of some incidents happening. One heading into on coming traffic another of the car driving up on a snow bank ( if the bank was not there the car would have ended up in a ditch ). There are caution indicators on the screen but none say stop do not drive. The first caution or warning indicator says stability control disabled drive with caution. Next indicator states traction control disabled drive with caution. Next indicator steering assist reduced steering may require increased effort. I find myself very lucky that no real damage injury or death occurred it was that dangerous on my over an hour drive. When the steering locked up in the parking lot i did contact tesla and initially everything was fine but locked up again in parking lot. I contacted them a second time with the wheel unlocking at the but no one said dont drive nor did any indicators state that actually indicated i could drive but with caution. I believe that if i were on a busy highway things would have been much worse. I was lucky. There was no indication of a totally locked steering wheel in there diagnostics indicators also nothing stating do not drive. Actually quite the opposite. I can provide driving video upon request. There were other warning indicators i have some recorded. None of the indicators stated a totally locked steering steering wheel lock up and nothing indicating do not drive. I would welcome your agency to come inspect this. It is a total danger to society.
