So your saying the last bars where fakes and I would have never made half the 20 miles only ten?
There certainly have been plenty of reports of milage dropping like a rock after thel low battery warning, so yeah, I think that's the prevailing theory.

What we really need is the updated service manual pages explaining the SOC % and the 12 display bars... Unfortunately I don't want to spend the $20 until I know it's updated...

I just got home from having the update done to my car. Went in with 85 miles range showing. They did not charge the car. When I left the dealership I had 101 miles range showing.

They must've updated your car with latest beta version of software that increases the range estimator :lol:

Re: Driving range display 'changes' after NTB11038 Svc Campa

I had the upgrade done Friday and immediately noticed my miles per kwh drop from 3.8 to 3.2.
Just did a 12 mile round trip starting with a 100% charge and used 4 bars and range went from 86 miles at start to 65 miles after the trip?
I know I definitely lost some efficiency due to lost regeneration because I started with a 100% charge but a loss of 4 bars (around 28%) for a 12 mile round trip?

I will have a better idea after my regular commute on Monday but so far I'm not liking what I see.

Re: Driving range display 'changes' after NTB11038 Svc Campa

OK. No one else here seems to have said this out loud yet, so I will. I had the recall software update done Friday. I think the bars are disappearing faster than an adjustment of the rate at which the last 15 miles decrease would warrant. What if Nissan decreased the available portion of the battery? Is there any way to check to see if we still have 24 kwh available? I'm not sure why they would do this, but I'd like to hear from those of you that have the means to check if the portion of the battery available for use is still the same following this recall work.
