Hi!
What really bothers me even more than Tesla's not telling me is that they have been downright not forthcoming when it comes to the whole battery warranty.
We purchased our S85 in 2014 from a previous owner's widow; it was one of his nine cars--no kidding--and had 1400 miles on it after a year. We now have 100,00+ miles on it and are still enjoying it when we're not sequestered here in CT. Several years ago, the battery failed. My wife came downstairs in the AM and the car was totally dead. Prior to that we had a connector problem that required battery servicing, but this time it was a full replacement. I was first told that we'd be getting a new battery, but they had to send the old one back to Fremont. That took three or four _weeks_! Whether or not the battery was new, repaired, or refurbished, I could never find out. I'm assuming it was refurbished. So, when I started noticing a decided drop in the ability to charge, which was roughly a 10-15% loss in range, I complained. No information that was useful was forthcoming.
So, here's my beef: only by reading this and similar blogs did I "discover" what had happened, after which and when confronted, did the SC 'fess up to say that yes, the charging has been capped. They said it was because I was supercharging, despite my having cleared that regular supercharging was not a problem, according to the SC some five years ago!.
The other beef? The amount of customer time wasted trying to find out and figure out what is going on is, in my book, an incredible time-waster and something for which I should be duly compensated. I'm not kidding. This is the same kind of nonsense that happens with computers or cell phones when the manufacturer elects to make a change or has a bug and the customer is left to figure it out on his own. That's a measure of product quality, or lack thereof. This is not useful in the last, although I will shyly admit that I do like trying to figure out some things; this is not one of them, however.
We've taken four trips around the US (our daughter lives in CA); we'll do it again and we may very well do it in winter. Loss of range is a new kind of "range anxiety."
Is there a model year or VIN after which the crippling did not take place? I'd like to know for planning purposes, especially if I want to do another road trip around the US.
Oh, and I understand that if you elect to upgrade your MCU or choose 4G, then you may have crippled function with the radio. I think most customers buy on the basis that the product will not be devalued by the manufacturer after the sale. I want to know more about the pending lawsuit.
We love the Tesla, still own some of their stock, plan to buy another, but crippling function is not my idea of honesty, even when 'fessed up to.
