52 highway miles on an SR/S means there is a massive problem with your battery and you should probably go through the warranty process.
Doesn't that depend on how fast you're going? "Highway" covers a lot of ground, from 50-60mph to open expressways 80-90mph.
Last night I got less than 50 miles with the cruise control set to 68mph. I also have the magic charging problem which isn’t how it’s supposed to work.
Everyone expects a battery with a 100k mile / 5 year warranty to last either 100k miles or 5 years. The reality is after 30-40k miles it has to be replaced and then after another 30-40k miles it has to be replaced again and you didn’t even make it to 100k miles.
I participated in the Zero circle jerk for over a decade but enough is enough.
WHERE IS THE BATTERY THAT WE ALL PAID FOR!?
