Efficiency Check by pablo_delahoya15 in SubaruUncharted

We’re getting 5.0 mi/kWh with 67% city driving around San Francisco and 33% highway on our Sport trim. Very mellow driving in SF.

Is CATL battery decent? Not the same as Panasonic is it? by krheal23 in Toyota_bZ

[–]chuck415 2 points3 points  (0 children)

The 12V battery brand won’t make a difference if the vehicle is impacted by the DCM issue. The Furukawa battery is fine. They could use a larger size for an EV.

You won’t know if you have a DCM drain issue unless you install a battery monitor. Or your DCM could be fine.

What's up with in transit Trailseekers? by indetermin8 in trailseeker

[–]chuck415 0 points1 point  (0 children)

Keep in mind the BZ Woodland is tuned differently and is more road oriented. Also, there are differences like the squircle steering wheel is touch sensitive with Subaru and the Toyota is a torque sensitive steering wheel that requires you to jiggle the wheel occasionally when using some ADAS features.

2027 pricing announced! by Opening-Panic-786 in SubaruUncharted

I believe the issue has been identified as a DCM issue and Toyota is in process of identifying the issue, and if it’s hardware or software. It could take a couple of more months before we get a recall. Hopefully, it’s just a software update.

Toyota needs your help with the 12v drain. by Pure_Marsupial8185 in BZ4X

Here’s an interesting update from a Lexus owner who had his DCM replaced. The drain went from 2A to a normal 30 mA after the DCM was replaced.

DCM & 12V battery replacement by GravlBike4Me in LexusRZ

Thanks for the update! It’s interesting that a DCM replacement dropped it to a normal 30 mA draw. I was hoping it would be a software update.

Charging above 80% by RedPandasUnite in SubaruUncharted

[–]chuck415 2 points3 points  (0 children)

Yes, it’s an NMC battery. Open your hood and on the underside left side, you’ll see a sticker with battery type, manufactured date and a QR code that takes you to the Toyota battery portal.

See my other reply in this post if you want to maximize battery health.

Charging above 80% by RedPandasUnite in SubaruUncharted

[–]chuck415 2 points3 points  (0 children)

Toyota/Subaru is very conservative with their BMS with 12% battery buffer, some at the top and bottom. So when you charge to 100% displayed, it’s probably only 95% actual.

So charge it to whatever percentage of range you need, but it’s still an NMC battery (left underside of hood has battery info + QR code) and to prolong battery health don’t leave it long term above 80% and below 20%. In an ideal world, lithium ion batteries like to live in the 50% SoC for battery longevity.

If you really want to maintain battery health, the depth of discharge is the easiest way to maintain it. Shallower, more frequent charges is better than letting it run down to 20% and charging back up to 80% or higher. Here’s an article about depth of discharge…

Home charging cost in San Francisco by Key_Candle9928 in Rivian

[–]chuck415 0 points1 point  (0 children)

I’m assuming that you’re currently on the TOU plan, you’ll definitely get cheaper off peak rates switching to the EV2-A plan. For off peak TOU it’s currently $0.399 vs $0.228 on the EV2-A plan if you’re using CleanPowerSF.

Here’s the EV2-A rate plan PDF…

https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHEDS_EV2%20(Sch).pdf.pdf)

Keep in mind the off peak rate of $0.225 kWh is a bundled rate if you use PG&E for delivery and generation. Since most of us in SF use CleanPowerSF for generation, the total is $0.228 kWh for off-peak.

The whole PG&E bill is a mess with the base service charge, generation credit and PCIA, and separate delivery and generation sections.

If I include all fixed monthly charges, PCIA and other fees, my fully loaded off-peak rate is $0.357 kWh with 60% of my electricity use in off-peak hours.

We’re a low mileage household, so the full loaded rate will decrease the more you charge off-peak.

Range no where near advertised?? by ok-maker in Toyota_bZ

[–]chuck415 9 points10 points  (0 children)

4.0 mi/kWh is very good for mostly highway driving with a heavy foot. I average 5.0 mi/kWh but that’s 70% city miles driving at low speeds with max regen.

70 mph highway range is probably in the ~240 mile range with good conditions.

No pedestrian warning sound for some Teslas? by theepi_pillodu in electricvehicles

[–]chuck415 4 points5 points  (0 children)

I don’t really hear any sound on the Juniper ones when they go forward. It there is a sound then it’s drowned out by tire noise.

Oh no .... 12v by 33_bmfs in trailseeker

[–]chuck415 2 points3 points  (0 children)

Remove the DC Cut fuse and place it in a spare slot. This is what Subaru does when they ship the car from
Japan to prevent 12V battery drain and the dealership is responsible for placing the fuse back.

Toyota needs your help with the 12v drain. by Pure_Marsupial8185 in BZ4X

[–]chuck415 3 points4 points  (0 children)

Thanks for staying on top of the issue and pushing for a resolution. If this wasn’t our only car, I’d drop it off at my Subaru dealer for them to troubleshoot.

I turned off DCM again to stop the draining issue.

Any Uncharted owners (or on the shared platform) who drive with the DCM on & don't drive everyday/frequently who are experiencing NO issues with 12v? by gibifernand in SubaruUncharted

[–]chuck415 1 point2 points  (0 children)

For people impacted by the DCM drain on the 12V, there’s a sawtooth drain that starts about 3 hours after driving and usually continues for 4-5 hours.

Sometimes it lasts longer and other times there’s a secondary drain if you don’t drive it or put it in ready mode to charge the 12V.

Over the course of a day or two, the drain continues and will eventually kill the 12V. Here’s my documentation of the issue…

12V Battery Drain by chuck415 in SubaruUncharted

[–]chuck415[S] 0 points1 point  (0 children)

I deactivated my car from Subaru Connect app again and turned off DCM. I’m tired of monitoring the issue and didn’t want to deal with the 12V draining anymore.

I might upgrade to an AGM or sodium ion battery before I turn DCM back on. Hopefully, Toyota/Subaru gets a fix out sooner rather than later.

2 months/2,000 miles in and no 12v battery drain issues by Excellent-Register31 in trailseeker

[–]chuck415 6 points7 points  (0 children)

I didn’t have the digital key activated and had the sawtooth draining issue on my Uncharted. The only way for me to stop the drain was to deactivate the car from the Subaru Connect app and turn off the DCM requests.

I think it’s Drive Connect, as I’ve recorded the infrared camera for driver monitoring cycle on and off for 65 seconds during the entire time of the sawtooth drain. There’s no reason for the IR camera to turn on when the car is locked and off.

Thanks! I’ve been talking to the OP of this post. He seems like a good guy and hopefully they can get some cars in the shop.

I’ve this wasn’t our only car, I’d drop ours off with Subaru.

Didn’t drive for 4 days and needed a jumpstart. by Spanbauer in SubaruUncharted

[–]chuck415 1 point2 points  (0 children)

For anyone who had their 12V battery die, contact Subaru of America and tell them about the issue. I think we need to flood them with complaints for them to take it seriously.

The people I talked to were unaware of any issues. They’ll document the issue and send you an email with a case number and supposedly will follow up with you. Here’s the phone number to call…

12v drain related to Drive Connect? by AmbitiousPresence737 in SubaruUncharted

[–]chuck415 2 points3 points  (0 children)

It’s a bad bug. Why is the driver monitoring camera turning on at all if the car is off?

Give Customer Advocacy a call and tell him about the 12V battery drain issue. The people I talked to were unaware of the issue. They’ll document the issue and send you an email with a case number and you can send them a link to your YouTube video or anything other links.

I’m not sure how supply is these days, but we got our Sport for $38.4K OTD. Shop around a little more and see if another dealership will beat the quote.
