The issue fixed by lowering the car is the same issue that has resulted in endless cv/half shaft replacements for the last 10 years. I went through 3 sets of replacements myself on my P85D until I lowered the car an inch.
I should say "re-lowered", because that inch lowering was just returning the car to the old stock height. In 2014, Tesla raised the car 1" after the bad press due to battery damage from debris strikes. When they raised the car, they started a long journey of pain and suffering for thousands.
The issue never returned after I lowered the car.
Their software update, which makes it better, just makes it better. If you lower the car when new, there's a good chance you'll never even need the software update, but both combined should do a great job of preventing the problem from ever happening.
It's been a while since I issued this warning. If you have lowering links, you MUST remove them before an alignment done by Tesla otherwise your car will be returned to stock height WITH the lowering links installed since they do a ride height calibration as part of the alignment.
