Is this Tesla's fault? Not entirely. But let's be honest, a small warning in the middle of the owners manual is not good enough.
I'm sure they feel it would be stupid to advertise something that to the general public looks like a defect with the technology. But I think it would have been better for them in the long-run if they were more informative. Now they are doing damage control, and a number of people have probably been turned off due to this whole saga.
tl;dr This information needs to be common knowledge amongst owners, Tesla could have avoided this if they handled it upfront instead of waiting for it to leak out on a blog.
They definitely inform the owner that completely depleting the battery will damage it. Why does everyone seem to think they don't?
The newer Roadsters even come with a system to notify Tesla if the batteries are too low. What else could they do to educate the owners? Make them take a weekend class?
You can destroy a Tesla by running it into a brick wall too. Yet there is no warning in the manual for that. Probably because it's not a risk unique to Teslas. Leaving your car at the airport for two weeks and coming back to find it suddenly worth $40K less than when you left it is more-so unique.
Tesla seems to be somewhat downplaying the high costs involved in forgetting to plug it in or leaving it too long.
It's not reasonable to assume that ordinary people know the inherent risks in lithium ion batteries. As such, the massive risk should have extreme emphasis in the instruction manuals, be explained in detail by the sales people, exist as clear warnings in the car, and so on.
I mean, yes. You can "destroy" your car by not charging it. You can also destroy it by accidentally running it into a brick wall. No PR spin will change that either. That the repair would be very expensive is a moot point - this is a maintenance responsibility to you as the owner. As long as you are aware that this is an issue - just plug it in. It's not like you can forget by accident when you're aware that letting it completely deplete over a couple of months will cause an incredibly expensive repair job.
So where is the problem?
