It's clear, Tesla's "warranty" has become BS. They try to get away with not repairing anything anymore. I even had a case where my SC was working on my car around fall 2018, had it for 1 month trying to figure out what the problem is (vibration with the car at high speeds)...I have an email from the SC Manager stating they see the problem, and they've replaced X, Y , Z, but the problem is still existent, however due to winter road conditions they asked me to take the car back as is and bring it back in Spring.
In Spring I took it back...and I got the response "Car drives fine under legal speed limits, we won't warranty anything above it"....despite the email that states "Yes there's an issue with it"
On the shudder issue, I've been getting the run around for over a year now, and my car warranty is about to run out...I'll probably get a "Oh warrantees over too bad" by the time a permanent fix is in.
