Same, it’s been almost a month for me with no word from Tesla no change in the underreporting.

I think the bug was introduced in 21.39.1 which was rolled out at the end of November. I’m now on 22.1.1 which came out in February, but I still have the same problem.

My guess is this is a bug introduced with the Nov 30 firmware. My system was fine before that, but started reading 20% low when the new firmware was installed.

I have an identical issue with my Powerwalls. Starting in December my solar production has been underreported by 5kW and my house consumption has also been underreported by 5kW. The house numbers are sometimes driven to zero when the panels are producing. I called Tesla Support, they logged...

This is my biggest problem with the new app too. The monthly numbers only show net grid usage, not import and export. There isn't a way to download this data either.

In Ontario we have 1:1 net metering, but the feed-in and grid usage are treated as separate transactions with tax charged on grid use and no corresponding tax credit on feed-in. Pretty much equivalent to the round-trip losses in self-powered mode.

What exactly is the difference between “off grid” mode and “self powered” mode? I haven’t seen any documentation from Tesla on the off-grid option.

Congrats @pz1975, great to hear that 939 has a new home! The car is perfect for twisty mountain roads, I'm sure you'll love driving it as much as I did. Feel free to send me a direct message if there's anything you'd like to know.

I replaced mine with a length of non-stretch Spectra line. Cheaper than cable and available at any marine store.

With the arrival of my Model 3 I'm considering parting with my Roadster. This is a rare opportunity to own Tesla's first production car, only ~50 Roadsters exist in the Canadian market and Tesla is no longer converting US cars for import. The car is a 2010 Roadster 2.0 with 55,000km on the...

Good luck! One word of advice from my experience with longer road trips - try to avoid freeways and take more direct routes on two-lane highways where possible. The shorter distance and lower speed both help to minimize the time spent recharging. Smaller highways are also more fun to drive...

@vinko - on the Roadsters we have access to the log files and service menus so we can directly read the Calculated Amphour Capacity (CAC). For the Model S you'll need to rely on the displayed range. My Roadster is now eight years old and the battery capacity is at 97% of original, I think both...

Error 1144 could also be the wiring harness or the connector. My service centre tried three different fans before they realized the harness was the problem. It was an easy fix to swap it out.

Another option is do a range charge and then let it sit in the garage for a day with the cabin heat running on full. You don't need to take the SOC down to "unknown range", the bottom 20% (in the red) is enough to trigger a recalculation.

I also had an intermittent 1144 PEM Fan error on my Roadster, it would come up randomly and seemed unrelated to PEM temperature or driving conditions. Tesla Service was able to fix it by replacing the PEM wiring harness. It could be a loose connection in your case too.
