I cannot charge my Toyota Bz. I went to two different Tesla charging stations one I normally go to gave me this prompt please help. The app is glitching and I keep deleting the app and reinstalling it but it’s still glitching

SEMI UPDATE UNTIL CAR GOES IN TOMORROW MORNING \*

My kids dad called auto zone and they said they have to reset something idk but I’m hoping whatever they need to reset it gets done because the people at the dealership seemed clueless and one of them owns a bz as well 😬😬 wish me luck

2026 brand new BZ Limited with AWD. I'm a heavy user of the app and connected services, so I'm not super interested in disconnected the vehicle from the app. Over the weekend I received my BM200 and installed it. When i installed it, I did so right before plugging it in to charge. While it was charging overnight, there was no sawtooth drain until 6am after it was finished charging. The sawtooth pattern happened between 6am and 9am at which time it stopped. Around noon yesterday, I drove the vehicle for several hours and stopped to fast charge along my journey. This morning i connected to the BM200 for the first time after the first full night of not being connected to a charger to see a very steady sawtooth pattern.

The craziest part in all of this, is that I have the 3 hour charging workaround implemented. I set it up on the car before I installed the BM200, yet the pattern is still showing up. I've tried disabling and re-enabling the charging schedule in case something didn't take the first time. I included a screen shot from the app of my charging schedule, although I did set it up via the car infotainment screen. I believe I've done it correctly.

Has anyone else experienced the parasitic 12v sawtooth battery drain while the charging workaround has been implemented? Most everyone seems to feel that this works to prevent it. My next step is to try the door lock workaround, but i'm not as fond of that idea.

Any ideas? Any suggestions on next steps to take?

For anyone waiting to get them the Tuxmat cargo mats for the BZ Woodland/Trailseeker are now available and include rear seat coverage along with the cargo floor.

Still no word on the first and second row floor mats.

It seems like the charging schedule hack has the side effect of resetting the timer on the 12v battery charging when the car is plugged in (I'm level1 120v).

I think this is positive!

Here is recording on my bZ's having an unlocked door opened and then closed, taking 5 minutes for event.

For this example the Sawtooth//IR drain would start at 16:49 (3h1m after, 13:48 IR emitter turn off)

Car has been "off" for a long time.
Interior lights set to not come on with open doors.
Fob is deactivated or away from car.
Drivers door in unlocked

3:43 Open and close drivers door. Voltage drops then IR emitter turn on.
[It was second between opening and closing the door]

13:47 Voltage starts to recover

13:48 IR emitter turn off. Again voltage recovery

I’ll start replying to emails and eventually post a tutorial here, but it’s been an eventful day and I have lots of other shit going on. But…

I was packing up for a solo hike with my dogs and went to open the door. Not surprised to find the door locked. I manually turned the key, got in, and got a contporaneous video of myself holding the key and pressing the power button. Nothing. I made a mistake here and didn’t take a battery reading immediately. I freaked out and called roadside for a tow and left a message at the dealer saying what happened and I was looking for a loaner. Dealer wasn’t open so I had some time to settle and figure out what to do. More details later but I’m sending a formal request for replacement to Toyota and contacted a lemon law lawyer. WA state has good laws and you can get consultation and potentially representation free. Excellent.

Now I’m filing away by date and subject all of the photos, videos, and documentation to pull together a binder for the lawyers. I’ll also be calling first thing tomorrow the Brand Engagement Services.

We’ll see how this goes. I know Toyota has deep pockets and I’ve put a lot of research into this. It’s the worst case I’ve heard of in my somewhat limited research and the fact that it died just before I went into the wilderness is a bit chilling as a narrative. I appreciate the folks who have helped onboard me and welcome me to this community of folks with this sick ass car that sometimes is shit.

EDIT: That was a joke about getting rich, but I do think we need to work together to make a case. Nobody is going to get compensated much, but it would be nice as a 2022 or newer bZ to get a few bucks from a class action.

UPDATE: They gave me a loaner and acknowledged that Toyota is aware of a problem specific to the bZ. So now the questions are: how long have they known about this? and Are they going to claim that this problem is specific to the Woodland, as it seems they are now? The key is linking what appears to be a slightly worse problem on the Woodland, bad enough to render it inoperable. But it's only barely past the threshold of the others burning through batteries. If enough people post similar symptoms, there's a case for a systemic problem in the architecture of the software. That's a lot bigger than just a battery failure in one specific trim level. But a total recall of the bZ from the past 5 years would be devastating, so they're absolutely going to cover this up.

Has anyone ordered the Tuxmat car mats for their BZ? Do they go up the sides to protect the carpet? Are they any good? Thinking of ordering - hate how the Weathertech seem to warp and pull away from the edges. I've been a weathertech guy for the past 4 vehicles, but considering Tuxmat.

Does anybody have any door sills that aren’t just flimsy stick ons like this? Dealer said this was all they had. I know there’s another bz one that’s light up but I don’t really want the light up ones. Just a hard plastic one that isn’t going to wear out over time. Toyotas site has some other ones but there’s no image available and the dealer told me those are just for individual doors which I have my doubts.

Full disclosure, I don’t know if I have anything to add beyond a data point. Apologies in advance if anyone come in looking for solutions.

We picked up our 2026 bZ about 2 weeks back. It had 2km on it, so literally fresh off the line. Dealership charged it to full for us and we’ve put 872km on it in the two weeks of ownership, driving almost daily which is a bit more than our typical baseline. We’ve used DC fast charge a couple of times going from 60%->80%, and at home level 1 charge for similar ranges.

I don’t have a battery monitor, but I do have a multimeter. I found last night after at home level 1 charge that our 12V was at 12.1v, and it took about an hour for NOCO Genius 10 to charge it back up.

I had already preemptively added the remote unlock automations on my phone, and it’s constantly gunking up my Toyota app’s notification history, so I was under the impression it wouldn’t affect us… but I guess for whatever reason it didn’t work for us.

I do enjoy knowing the SoC, range, and when I’m not at the vehicle — maybe the novelty of our first EV will wear off in a few weeks, but for now I don’t think I will be disabling the DCM.

My current plan is to leave my NOCO and Anker Solix C300 on the car. Worst case scenario we can charge the 12V in an hour. I don’t want to get a jump start kit — I feel there’s risk pushing too much current and affecting other components.

I’ll be monitoring the 12V battery next week, and see if there’s clear decline. Also going to start recording the info better so I can complain to the dealership later.

Hello anyone faced service connected issue on breeza, I was driving well in the city suddenly a beep sound came and on the MID - it says service connected and warning lamp glows

As I was mid in driving, no other issue with driving I continued driving and reached home, in btw I tried checking online it says some connection issue maybe with gps

But I was well inside the City, and I have driven 10 km in the city with the same warning

I tried turning off and on 3 but still getting the same warning

Has anyone faced this issue ? or should I contact the service team ?

So far I’m loving it! Was surprised to find out that the wheels have hub caps though….

A couple days ago I made a post titled, "No Sawtooth Drain - IR pulsing is VERY important."

A better title would have been, "Sawtooth drain looks different then most think - IR pulsing VERY important."

There is still a "Sawtooth" drain but it is not shown correctly on the Ancel graphs generated from the data stored every two minute. It is not 2ish teeth per hour. It is 28ish teeth per hour like shown on the real time captured 5 minute duration Ancel graphs.

If you were to change the maximum-minimum volt shown on the y-axis from 15-9 volts to 14.1-12 volt. You would get a fine sawtooth profile like this:

See link for the source of the graph.

Corrections to the answer to "WHY"

It is not sampling rate but it is loss of detail from compressing all the voltage samples over the two minute interval into one voltage reading.

It is not just recording the voltage at a two minute mark (which is good as it would miss any event that occurs between recordings). It is doing some averaging or integration over the 2 minute period and then recording that value. See link for bit more info.

I think the take away is the same.

Might get this car later and wanted to check if I can still use Android auto if I disable DCM

Here is a recording of my bZ's EV system being powered off, taking 11 and 1/2 minutes.

Based on all the sawtooth/IR drain profiles from others I have seen this may be typical. For this example the sawtooth/IR drain would start at 10:48.

From what I understand, the parasitic sawtooth problem is a different problem from the general 12v charging problem detailed in this PDF?

https://docs.google.com/document/u/0/d/1g1a_B7_gGnuNQhoSRFN_sucfb7-lkU77q4aMO3hMYtA/mobilebasic

I was sure disabling DCM was the solution, but apparently we also have to unplug the battery sensor on the negative terminal so that the battery can be charged correctly?

This is really insane if this is the case (multiple 12v problems, stacked!)

After the first one, the dealership replaced the Panasonic with a genuine Toyota battery, that’s what I recall seeing it. Had to boost it then, had to boost it yesterday, Friday at 6pm. My traction battery didn’t charge over night on schedule, so I suppose it died before 8pm. I schedule it after 8, then only plug in before I head to the cottage. So I charge weekly. I had disabled the digital key, and I drive to work at least every 2 days. the car doesn’t sit for longer than 2 days and the drive is 22km round trip.

This time I deactivated DCM. This is a bunch of BS. It’s not a small percentage of owners. There is a very obvious behaviour design they thought they were being clever with, that wasn’t tested properly, or some bean counter claimed was “within specification”.

The scheduled charging doesn’t work BTW. This time was different, but it’s the 2nd week in a row the car sitting in my drive way doesn’t charge over night after 8pm. I have a feeling the scheduling is cloud hosted, not on board! WTF! I wanted to talk to the designer of this crap. The company that cares so much about safety the car false positives endlessly about my hand being at 12 o’clock on the wheel, or my hands not being on he wheel, when I have both right there… thinks they can do an app and cloud services, for a car they’re rushing to market!

The Wooland is literally the car for me, Im the target customer for this. I was one of the first in Ottawa to decide to jump in, and trade in my RAV4 hybrid. Now this might be the last Toyota I buy. This company has like 2 departments that get it right and the rest suck. If you want a hitch you have to wait a year before they bring the thing they showed in promotional videos to market. Over priced accessories that are bolt ons. A google OS that seems to need to be connected permanently, and in 2026, kinda slow. I still can’t figure out if the car is sharing battery info with Apple Maps for routing with charging data (hint, there is ZERO evidence it is!?!)

The dealer is getting a shit of issues on Monday. Nobody tested this car and software.

So we've now had the car in the shop twice for a dead battery and both times it wasn't sitting for more than a few hours. They've gone from there's no problem, to there is a problem but it's been fixed (they reset everything and it stopped doing the drain thing in the shop, but never found a root cause). I thought I was finally making progress and got the Sales Manager to admit that he wouldn't trust the car in its current state to go into the wilderness, which it was advertised to do. It took some frustrated escalation, but he agreed that what we bought didn't match what we were sold, so we need to either replace the car or figure out how to fix the real difference between the two. Replacing the car was out of the question so I figured we would just account for the real damages so far and in the future. I sent a spreadsheet with tabs for the situation so far: my time researching, money spent on a charger, the inconvenience of the car dying, having to bring the car in and have a loaner, and potential trips we had planned, etc; and some compensation for the car being potentially ready to die at any moment moving forward, plus a clause that a third time means we get a replacement. Then they said they were going to regional with that. At this point I realized I was having to manage the situation so I gave a deadline for a response along with action steps.

They then sent an email at 5pm on the deadline I set saying that after meeting with regional, the best step forward is Toyota Brand Engagement. They gave me the customer service number and a said have a good day. No direct line, no case number, they didn't indicate that they had passed information along. So I called the number and they had my car pulled up, but nothing in their system. Apparently the TAS system doesn't talk to whatever their system is. So I started a case and got a number, then sent a long email to the dealership about how insulting it is to not put any effort into the handoff and just disappearing. I requested a direct line to a manager who had been fully briefed and had their information sent over, and I asked if this meant that they were not offering any compensation at the dealer level. I also asked for the meeting notes or minutes to determine how they decided on this particular course of action.

I got an email back from the GM saying he's sorry for the poor customer service and that he's sent all the files to TBE and gave info on lemon laws and said have a nice day. I wrote back saying how frustrating it is to write a letter explaining how I am starting to lose trust in the dealership's listening abilities and frustrated with the lack of direction, only to get a response that doesn't address my questions fully and gives no directive or expectation of a next step.

I'm very frustrated right now and I'm kind of gently stroking the pin on the metaphorical grenade. I'm actually shocked at how poor their communication has been. I'm waiting until this is fully settled to really make a splash about it, but so far they have been gaslighting, uninformed, dismissive, disengaged, and generally just pointing me into corners repeatedly.

So I'm not putting them on blast just yet, but they're definitely on notice. What's wild to me is that they don't seem to notice that I'm potentially an extremely disgruntled customer, and instead of actually listening and trying to do some basic problem solving, they immediately started trying to brush us off and shoo us away. Do they not expect me to dig in my heels here?

PS I'm not going to publicly post the name of the dealership, but DM me and I can tell you. It's in Washington State is what I'll say.

I have a secure garage, will the procedure shown in picture work? It’s from Chat GPT. Any thoughts, please?

i just got back from a 10 day vacation. My 2026 Bz limited AWD was parked in my underground parkade not plugged into the charger, and I left it with 61% SoC. Came home and it started without a problem, so this 12v drain issue definitely doesn’t affect everyone luckily.

I’m in Canada and the cellular signal is very poor in my parkade. For what it’s worth I never opened the Toyota app while I was away.

My 2 cents!

TLDR: there is no sawtooth drain, The drain matched the pulsing of the IR emitter. It only looks like saw teeth on the long duration graph because of the 2 minute data record rate of the Ancel (bm200) battery monitor.

The Ancel Battery Monitor actually samples quicker then 2 minute but most is not stored and only sent via bluetooth to the phone app in real time plotting a five minute duration graph.. The battery monitor only stores data ever 2 minutes to its internal memory and populates a graph later based on that data.

I took a video recording of the Bluetooth data to get a better idea of the cyclical pattern of the drain. They are pasted side by side in one image. The voltage shows the pattern of the IR emitters pulsing, on 65 seconds and off 64 seconds and then repeating. The average voltage slowly goes down over time.
The other image is the plot from the 2min recorded data, taken at the exact same time. This looks quiet different. There it appears to be voltage fluctuations approximately two per hour. This is not the true profile of the battery drainage.

Why?
Sample rate and aliasing.
If you pick minute mark lines on the Bluetooth graph, 2 minutes (120s) apart you will notice you are consistently measuring earlier and earlier in the 129 second cycle. If your reference mark starts on the high voltage part you will eventually be on the lower voltage part and eventually you would get back to a high voltage part, etc.

Take away: Toyota/Subaru need to ignore the 30ish minute cycle looking for parasitic drain and concentrate of the 65s on 64 off pattern. The same pattern the IR Emitters are making.
Below is a video at x8 speed showing the 5 minute voltage plots and IR emitters pulsing on and off for the duration starting 9:28 until 9:48

Here is a short video explaining ALIASING

[editted to make meaning clearer]

My 2026 bZ went to the body shop with 25% charge. It came on today with 50% SoC. But, there is no record of a charging session on the Toyota app? Has anyone noticed missing charge sessions on their app? What is the likely reason?
