Energy Consumption graph WAY off after software update

[BrunOfOne]

New owner here, I have had my Y for 1 month and 1200miles.

I did the software update Wednesday evening that added the Icelandic language. Then yesterday I did my normal 36mile commute to work. After about 5 miles of driving, the "Energy Consumption" graph started going nuts and showing MASSIVE spikes and very high average energy usage. I usually get around 240-250wh/mi on this commute. By the end of the 36miles, my usage on that graph showed 408wh/mi over the past 30 miles. HOWEVER, the "Drive" screen showed that I was doing better than rated range. Indeed, I burned 11% of the battery going 36 miles which is pretty consistent with rated range (and past experience) and nowhere near 408. Nothing was different this day, it was 57F and dry out, and I was driving like a granny. I also saw this same behavior coming home yesterday.

Anyone else see this??? Very annoying it seems like a simple SW update broke this particular graph.

There is a thread here with similar feedback:

Problems with “energy app”?

Hello, I was chill driving yesterday on a highway hoovering at about 95km/h fascinated about relatively low consumption of 140wh/km considering misty wet roads and wild wind. The consumption tab was also showing more or less the same (10,25,50 km) as always however, at some point it started to...

Since upgrading last night, I’ve noticed my “consumption” Graph is showing a average of 430 wh, but my trip odometer is reading 240 wh for the same distance/drive.

The sample size is about 150 miles.

Is anyone else seeing this issue?

I have the same issue after the update, rebooted and problem is still there. The drive screen is working fine. Not sure which data is used to decide when and where to stop for charge on long trips.

Interesting. Another user pointed me here after I posted this for my 2023 Model 3 Performance. Also not long after the 2023.6.8 update:

Yes, mine doing it as well. I was driving 55 on flat ground today, and the Consumption graph showed me using 900 (!). Crazy. I had 82% battery, and it was showing me a range of 81 miles. As usual with updates, one step forward, eight steps back.

Same thing on my model 3 and it almost feels like how much its off is based on accidental conversion of Km - Mi.

My car is set in KM but numerically the value for wH/distance or estimated remaining distance seems as if its assuming Miles instead

Well I saw this crazy behaviour on my 3 weeks old model Y LR, after installing update 23.6.11

Anyone seen this get fixed yet? According to my Consumption tab, I'm averaging 760 per mile! The card tab still shows 260-270.

some people claimed that changing the wheel size, drive a while then change back would solve the issue, not for me.

I'm getting the opposite problem. I use to average 243 wh/mile (I drive like a granpa, I guess) which went up to around 260 when I got new tires, and then when the last update went through, 2023.12.5, my wh/mile got better (in the 220 wh/mile range) - definitely not a weather change or tire pressure or anything. I'll have to check the Energy app vs. the Trip box to see if I have the problem reported here.

Same here after 2023.7.10 (Model 3).

I went to that other thread, sat in my garage and changed the wheels to 19" Sport. The system rebooted. Changed back to 18" Aero, system rebooted.

This morning it's all fixed!

 

[rayrevolver]

.. nevermind. Hosed up today even worse. Doing the wheel swap thing today didn't work.

This issue is still present for those on FSD beta 11.4.x. It’s really annoying.

 

[tampaboyt]

Noticed it today , facing same issue> energy consumption graph has massy spikes (900 wh) ...model Y LR bought 3 weeks back

 

[CaseyL]

2023.7.15 (11.4.3) seems to have fixed it for me.

 

[tampaboyt]

latest upgrade fixed the energy graph but the current drive trip reading is messed up...its showing 1200wh usage

 

[OKLakegoer]

Same issue. I did get an update and it fixed it for like a day. Back to crazy scales on energy consumption. Current drive is fine.

 

[rayrevolver]

Installing 2023.7.20 right meow. We shall see!

***I'm on a Model 3 LR, so that why my numbers are so low. Just a reminder***

Installed last night. I also changed the Wheels in Service to the 18" Aero without the covers, so that did a reset.

This morning drove to/from camp (same drive all week). Temps were 73F and I didn't use a/c. EDIT: Forgot, it was damp but no rain, so I expected energy usage to be higher with wet roads the whole way. On the way home it sprinkled lightly.

This afternoon the temp should be 79F and I will probably use some a/c. Might rain, you never know.

The good news is the Current Drive/Since Charge/Odometer seems to be fixed:
31 miles, 6 kWh, and 195 Wh/mi. This is good and is what I expect. Did this same trip on 2023.7.10 and the best I could do is ~225 Wh/Mi.

The bad news - The Energy Screens are still off. I can try another wheel type reset before I run out. Its not going to be the same trip but its obvious the Energy shows averages over 300 Wh/mi which is insane and the unusual spikes to 600+ Wh/mi.
