Have you taken delivery of a D model (P85D, S85D, S70D) in the past few weeks--say any time since May 1, 2015? If so, it would be great if you would help with some simple data collection, so that we can figure out whether an issue has been resolved or not. I'll explain. There was an issue with the D models' odometers that saw them all overstating actual distance traveled by about .8%. There is a thread on this topic, which I'll include the link to below, but you don't need to read the whole thread to help. In fact, you don't need to read any of it, unless you want to. Do P85Ds and S85Ds have inaccurate odometers that overstate distance traveled? In a nutshell, the problem was identified, and then confirmed by a good number of users, driving on both the snow tires and all season tires that are sold with the cars. Though the variance was within specifications, this inaccuracy had not existed in prior Model S models. Since it was consistent at .8% we hoped that it might be a simple error in a formula. I wrote to Tesla, letting them know what we had found, hoping it might be an easy fix. Since coming back from having my winter wheels taken off and my all season wheels put on in late April, my odometer is now providing accurate mileage figures. My P85D was also updated to firmware version 188.8.131.52.188 (.188 for short) at that time. I initially attributed the fix to the firmware update alone, but others with firmware .188 were not seeing the more accurate odometer readings. Someone suggested that perhaps the fix was in the firmware update, but that it also required either a TPMS reset and/or a wheel change for the fix to take effect. This is where you, as new owners, come in. Assuming you took delivery with version .188 or later, the fix, assuming there is one, should already be on your cars. If that's true, your cars will have accurate odometers. It would be great if you could record some trips, comparing the mileage your D reports to some other reliable source for the actual distance. This could be something like Google maps, or a GPS system--you get the idea. You would just post with information as follows: Model: P85D Delivery Date: May 5, 2015 Current Firmware version: .213 Firmware version at time of delivery (if known): .188 Odometer MileageActual MileageSource (Actual Mileage) 24.324.4Google Maps57.957.7Garmin GPSI'm sure you understand. If you have any questions, just ask. If we get even just a handful of people reporting even just a handful of trips, we should be able to tell whether or not Tesla has solved this problem in the Ds. Once we have some data to report, I'll update the thread above as well. Thanks a lot!
