Took my first road trip in my 2024 Tesla Model Y LR DM and for the most part it was FANTASTIC. The drive from Richmond, VA to Houston, TX was LONG and required several stops to charge. The good news is that EVERY ONE of the SuperChargers I encountered worked perfectly - even the ones along I-10 in Mississippi and Louisiana! The car road comfortably and didn't have any physical problems during the trip.
However...
I did start having this weird problem on day 2 of the trip (Montgomery, AL to Houston, TX). I'd charge up and it would show my arrival at the next SC would be with ~20% charge remaining. Cool.
Then I hit the interstate and watched that number drift down to 19...18...17...16... and by the time it got down to 8% I decided to change my plans and stop at the next SC I came across instead of pushing it to Mississippi. Charged up again. Again: 20+ SoC predicted at the Mississippi SC. Hit the road again...
19... 18...17... 16...
WTF?
So I stop at another SC, the 3rd SC on I-65 between Montgomery and Mobile.
Same thing again.
By the time I got to Mobile I was resigned to the idea I'd be stopping at every single SC I came across between Alabama and Texas. But I didn't know why.
Somewhere in Louisiana I tried rebooting the system. Same issue.
At one point I decided to start looking at miles of charge remaining vs distance to the next SC. This is where I noticed what you see in the pic: 193 miles charge remaining, 194 miles to the SC. That means I should get there with 0% remaining. But you can see it says I'll have 11% remaining!
WTF again?
I realize weather (rain, headwinds, etc) and terrain play a role in miles you get from a charge but this was just ODD.
For the rest of the trip I completely ignored percentages and only looked at miles SoC and miles to the SC I was shooting for and everything worked out.
Anyone have any suggestions on what's happening here and/or why I didn't see this happening on Day 1 from Richmond, VA to Montgomery, AL?
Thanks!
