And what incentive do the thousands upon thousands of people with no car trouble have to search for such a site and add their car to the database? Any site that relies on voluntary reporting ALWAYS has a huge bias towards the small percentage actually having issues.
Consumer Reports and Tesla are the only ones who have valid data on MS reliability, the former claims reliability is Average, the Later hasn't said. ALL other sources are useless for the purpose of determining reliability.
And as a side note, don't ever click on seekingalpha, it's all garbage from people with a huge vested interest. you'll never find anything unbiased on that site.
Consumer Reports data is inaccurate for many reasons and is obfuscated. Truedelta is open shared data updated quarterly versus the yearly data CR publishes. I'd argue this is analogous to Wikipedia and the internet in general vs hardback encyclopedias. People wised up and stopped buying outdated overpriced hardback encyclopedias at some point and I think it was worth the transition.
It's in the interest of all consumers to join Truedelta and add their data. It's the same reason people write reviews on Amazon or on Yelp or any other site that allows users to submit reviews. It's just that for Truedelta you input data quarterly not a review. The sites owner does the work with the statistics to reduce bias as much as possible and if you read the documentation on the site you'll see the mathematical differences between TD and CR laid out for all to see.
Seriously if you don't know about it don't diss it, just read up on it or ignore it. But if you care about cars at all you should spend some time looking at the site and the data it has and go ahead and add your data to the mix for the good of the community.

And to be clear if you google Michael Karesh (the creator of truedelta) you'll find he is not anti Telsa and posts constructive supportive comments when discussing Tesla. His site and his posts that I've read are about as vender neutral as I've seen (so long as you look at content about the car companies and models and not about Consumer Reports).
