There are threads I avoid because of this. Enough already. Even worse when the poster starts repeating the complaint in every thread they visit. WE HEARD YOU.
To second Bonnie here, and to set some context -- I'm one of those people with a drive unit replacement.
First and foremost, this issue seems to come up (and has) for more than year on these forums. As the old adage says, "there's nothing to see here, move on."
Look, I'm an early adopter. I have a low VIN number. Innovation is messy. I suspect the majority of us suspect that on some level, which is why we are here. We like to be on the edge of change and drive it. We want to transform the driving experience for those that don't live on the edge, and make it the norm.
I'm not expecting perfection, but appreciate that Tesla strives for it. I will also go on record that they have gone WAY out of there way to treat me right as a customer. I have ZERO complaints about the service, follow-up, and professionalism of the team. Tesla often notes issues (based on data, which I appreciate) and keeps me on the road with no disruption of time. The one time I had an issue the calvary came -- quite literally, and I had a sum inconvenience of 30 minutes.
So turning back to my drive unit, was I concerned? No. It's a new vehicle. Tesla is experimenting with technology, bringing it to the mass market, and continuously improving it. Unlike any ICE vehicle I've owned, they keep making my car better, long after Elon Musk handed me the keys in 2012. (Yes, I have pictures.)
So here's my thought: rather than assume the Company is going to not treat it's customers the right way -- when they demonstrate tirelessly the opposite -- how about we trust awesome engineering and let them do their job? I have 100% faith and trust in their follow-through, and I'd encourage all of us to do the same.
