My 90% was almost exactly the same as yours (low 230s) until this last week, so thanks for the data point!. Looks like more evidence that something is off in my battery. The whole "algorithm based on driving style" must just be a misunderstanding. Maybe the algorithm updated, but it'd be for how it measures the energy, not on how I drive, that'd be silly.My "classic" just got the update as well, Didn't change anything regarding rated range. Last week it was 232@ 90%, this morning 232 @ 90% post update. BAD module!
I think you're on to something here.I find that whenever customers complain to Tesla about their range dropping, Tesla pulls out the stock (and inaccurate) answers to try and make you go away. I'm sure that 90% of the time it's probably just owners not understanding rated vs ideal range, but the rest have legitimate issues.
If the customer complains about range loss, they probably switched from Ideal to Rated. If they still complain, make sure they're not looking at Projected. If they are looking at Projected, then advise that this is based on (recent) driving habits.
If the customer complains about range loss, they probably are confused about Ideal, Rated, and Projected. Projected is based on driving habits. Also the algorithm for measuring capacity is adjusted periodically via firmware updates.

Ideal is not more accurate than rated in assessing battery capacity. It's just a different way of expressing it. The problem is battery capacity can't be measured directly, so any result is an estimate.

My service center has always been good to me and I've known some of those folks since they day they started on the job. Portland's service center was one exhausted, overworked fellow relocated from Seattle when I got my car, an awesome fellow, loved talking with Jason. I'm optimistic they'll put in the due diligence, they always have before, and often above and beyond.
Once again, rated range has nothing to do with your driving habits. It's the range on the EPA test cycle. Period. Full stop.It could be that the new software version needs to relearn your driving habits, so you may want to give it another two weeks to adjust. Try also driving from a 90% charge level to 10% at least once.
That is just silly. Forward a complaint with your SC notes to Tesla corporate.I contacted the local SC. They claimed that my logs were fine and blew me off with "it's a firmware bug." They told me to charge to 90% nightly instead of 70%. I emailed Tesla; they brushed me off also and told me to deal with my local SC. After doing charging to 90% instead of 70% for a month, my 90% is now up to 133 miles. Oof.
Thanks for the suggestion. I emailed ServiceHelpNA at tesla.com. The reply I received on June 9 is below. I've received no contact since then. Is there another email address that I should try?That is just silly. Forward a complaint with your SC notes to Tesla corporate.
I was thinking of Jon McNeil, the VP of service.Thanks for the suggestion. I emailed ServiceHelpNA at tesla.com. The reply I received on June 9 is below. I've received no contact since then. Is there another email address that I should try?
Hello,
Thank you for contacting Tesla Customer Support.
I have documented your feedback on the request tracking this issue and have escalated to Service Management. As far as a fix for a bug and possible issues with the battery it’s a question that would be best handled by our Service Team. We appreciate your patience as we look into this matter and we will be contacting you for a follow up in the next 1 -3 business days.
