Forums for every vehicle type are generally negative. No one gets on and talks about every great experience, by in large people get on to bitch when things are bad. The proverbial 5% make 90% of the noise type thing...
Enjoy your MX!
While I agree that forums are inevitably biased for all the reasons stated, I do think an earlier poster is correct. The actual mechanisms for Tesla service are clearly designed to be low cost for Tesla rather than customer focused .. it IS hard to contact them, and it IS hard to get the information you need.
Several people here have said that is to be expected as Tesla move from luxury cars to mass-market cars. Um, sorry guys, my M3 cost over $65k after tax, and that is easily BMW/Audi/Lexus territory. Now I'm not saying Tesla service is WORSE than these others (though Lexus sets the service standard here), but I dont think "Tesla sell mass-market cars now" is a valid excuse either.
The reality, of course, is Tesla have grown fast since the M3 shipped, and the service infrastructure is strained. Hopefully, they will respond to this (actually, imho, they have no option if they want to remain viable long term).
