As just one example, I was unable to start my new model 3 on a cold morning after owning it for 3 months (which in itself is horrendous). The entire system shut down and would not start. This was particularly problematic for me as I am required to get into the hospital in under 30 minutes in order to treat stroke patients. As such I ended up having to use an uber to make it to my surgical list.
As is typical for uber, it was impossible to get hold of a human to resolve the situation and the replies (from whatever it is that replies to you on their app) refused to help me unless I waited at my car for their service to show up.
When I finally got hold of someone I was told that in order to prevent this, I should prewarm the car using the app prior to using the car. No-one ever explained this to me prior to this happening.
I would like to say this has been the only incident but there have been innumerable problems at every point as a new owner.
