Individual service centers have gone through rough periods before - which Tesla was able to address.
This time - it's different.
As locations start seeing Model 3 deliveries, the number of vehicles supported by each Service Center increases rapidly. This is putting straining customer support and service network in North America now - and will start impacting everywhere else next year.
And, this time Tesla is continuing to increase production - so they'll be facing these challenges more quickly now.
At the same time, Tesla is pushing to achieve profitability - which makes it more difficult for them to add infrastructure (service centers, mobile service vehicles, staff).
But, Tesla has a huge advantage over ICEs - the amount of service and support required for each vehicle is significantly less than for an ICE. And many of the issues can be handled over the phone or by a mobile service vehicle - not requiring going into a service center. So the amount of infrastructure investment needed by Tesla should be considerably less than the ICE manufacturers.
The next few months could be challenging in some locations - but for Tesla to survive (they are now outselling Jaguar worldwide, and BMW/Mercedes in the US), they'll have to figure this out.
For now, it may be a little frustrating to get support and service - though with Tesla's track record so far, it's likely they'll work this out - and continue to provide the service and support that has resulted in strong customer loyalty.
