For those not reading the small print everyday it looks like Tesla have changed the Ms and MX battery and drivetrain warranty to now ne limited mileage. On the flip side they've now added a performance guarantee and its broadly in line with the Model 3 which loses one of the advantages of the MS and MX for high mileage drivers.

The more worrying aspects however are they now want to exclude drops in capacity or charge rate as a result of a software change as opposed to degradation. #batterygate and #chargegate owners will understand the concern

Secondly, they've updated myTesla to the NEW document even if its not applicable to the date your car was manufactured. As it only happened yesterday its anyones hguess whether they will try and apply the new rules to old cars.

If you want to see the rpevious versions then I've put them here with their publish dates. If anyone finds a version I have missing I'll happily add it.

There’s another thread that touches upon this, and you’ve not picked out the important bits..

“The Battery, like all lithium-ion batteries, will experience gradual energy or power loss with time and use. Loss of Battery energy or power over time or due to or resulting from Battery usage is NOT covered under this Battery and Drive Unit Limited Warranty, except to the extent specified in this Battery and Drive Unit Limited Warranty. See your owner documentation for important information on how to maximize the life and capacity of the Battery, failure to follow these recommended battery maintenance and charging procedures shall void this Battery and Drive Unit Limited Warranty.
Your vehicle updates its software wirelessly, constantly providing new features and improvements for your vehicle, including updates to protect and improve Battery longevity. Any noticeable changes to the performance of the Battery due to these software updates are NOT covered under this Battery and Drive Unit Limited Warranty.”

this seems to say two things.. the first part that normal degradation isn’t a warranty matter and could be read that the 70% performance threshold doesn’t apply. The second part says we can send a software update that takes away range and that’s not a warranty matter either.

Tesla write some dreadful documents, you can interpret the above as either “we warrant 70% irrespective of how the reduction occurs” or “we warrant 70% excluding normal degradation or as a result of software changes”

Why? Batterygate, chargegate, reducing the warranty provision in the accounts to eek another % out of gross profit, because they’re in a dominant position and new buyers won’t be bothered as it will not hurt owners for 3 or 4 years.
