Has anyone had this before? Yesterday the nav started my regular journey telling me I’d have 70% battery left at destination. Usually I can increase this a bit by driving carefully, so I didn’t think much of it as it started to tick up to begin with. I even commented to my wife how awesome my driving must be because we’d gained 9% expected SoF at arrival.

As the journey went on, it started showing that I’d arrive with MORE charge than I had currently and continued to increase during the journey until I arrived with 70% but the Nav showed I would arrive with 99%.

stopping the Nav and reprogramming didn’t help - at 75% SoF I cancelled the Nav, turned the car off, turned back on and entered the destination and it said I would arrive with 95%.

it’s a journey I do often so I knew exactly what to expect, but I’m due to go in my first Euro road trip in a month and this kind of error would make life difficult. Wondered if anyone else has experienced this. My return journey is tomorrow so I’ll be able to see if it miscalculates again.

No, not seen that one before.
It's not assuming you are going to stop and charge it just before you get to your destination is it?
Mine does things I dont expect when in 'range' mode and I get the minimum SoC wrong.

Happened to me once. It’s a bug I think. Never happened again.

Happened to me 4 days ago but my case was even more obvious…100 meters from home the deviation was 15% actual battery charge and 29% expected charge with no charging stops ! Maybe it was expecting a lightning strike around the corner ??…

Good to know it’s not just my car - have you guys had the recent software recall update? I didn’t bother to book mine because my nearest dealer is over an hour away
