Model S odometer accuracy issues.

[vinS0021]

I'm an early adopter, had my S signature since Oct 2, 2012...vin 211. I took a short road trip today ~150 miles and noticed that the odometer was not incrementing each mile. It jumped 5, 2, 3 ,1... inconsistent increments. Not sure if it is incrementing after the miles driven or before. Opening a service ticket, but was curious if any other owners of an S have noticed this issue. My current software version is v11.1 ⁦(2024.2.7 d522c44937f7. Looks like I'm current with updates. I've known for awhile my speed is off 1 mph for every 40mph but I never noticed this odd incrementing of the odometer before.

Are all the trip odometers recording this inconsistency? I believe there is a second official odometer in the black box that can offer a backup of correct mileage, in case the human interface odometer goes bad or is replaced. I'd have it looked at before you lose the true mileage. That will cause all sorts of issues.

Thanks and yes, that is my fear. Checked the trips and as I suspected they have all been reset multiple times by service where power was disconnected. Have a mobile service appt for Friday...we'll see what they say.

Also, check the odometer at the bottom of the home page in the phone APP.

Odometer behind the steering wheel and odometer in app match. Hopefully it's the correct number.

Chatting w/ service...memory was at high utilization so they cleared a majority of that. Apparently the trip odometers eat a lot of memory. Still having the odd incrementing so we are on to a factory reset...ouch.

Factory reset is painful but car gave me hope with the odometer incrementing correctly for the first 2 miles...then nothing for the next 8 miles. I gave up and went home. Service is researching.

The definitive answer from the service center...appears all cars on this version of firmware will have this issue. See pics for technician note and firmware version.
