Today I measured the voltage of the 12 V battery, and it came out to be 12.1 V. I started the car, but today the hybrid system behaved normally. Could that 12v battery be the cause of all the problems? 

There are apps on android and iOS that can help you monitor your Battery 🔋, and hybrid system. With suitable obd 2 adapter like Carista from Amazon for example.

I was thinking of charging the 12v Battery for the weekend, but I don't know how to raise the back seat. I tried to pull it up but it doesn't work. I don't know where to press the seat to separate it. I don't have any feeling and I'm afraid I'll break something.

It’s just pull up stronger. There are other posts about this with pictures and explanation. 
If you worry about it you can connect charger to the jump start points under bonnet in the black box. Or just start the car and leave it in ready mode 40-60 min.

I don't have electricity in the garage. I have no choice but to take out the 12V Battery and charge it in the apartment I felt like an idiot for not being able to raise the back seat. 

[Aldino]

I did not know that if the display shows that the Hybrid Battery is at 100%, it is actually at 80%. I was afraid that overcharging the Battery would accelerate its life hybrid Battery.

Use the Ready mode then. Taking the Battery out is going to be much more complicated. Turn off AC, lights and fans and keep an eye on the car.

Today, my engine started up again and dosent switch on hybrid while driving in the city.   it quickly charged the hybrid battery to 100%. I turned on B mode again and everything quickly returned to normal and the hybrid system started to turn on EV mode. The 4-month-old car has already started to get annoying. It doesn't look like Toyota quality and reliability. 

What are you talking about?   Why are you getting hung up about all this and talking garbage about reliability.   My Lexus often charges the Battery to 100% and so did the Yaris and Yaris Cross so they’re all faulty according to you.  I take it you are running around with the climate control off because if like any normal person you are not, the engine will run.

If the hybrid battery often goes to 100% and the engine  overcharged battery, this reduces its shelf life.  

No it won’t, that’s more nonsense.   The display shows the normal range, it doesn’t turn red or give a warning at 100% charge, nor does any Toyota literature anywhere say the Battery shouldn’t get to 100%.  Forums attract closet experts that seem to know more about the way a vehicle works than the people that developed them.  The people that design these systems have forgotten more than you know about what should and shouldn’t happen and not being their first rodeo have protected the Battery from overcharging and it’s outside and above range shown by the graphic that you hang your claims of poor quality on.  Get a grip.

B will not cause damage but adds unnecessary stress to the hybrid system and only should be used in specific situations like continues downhill descends, there is no distance specific or time but as soon as you drive on level ground better to flip to D. 

The B what actually does is two things: 

1. Increase regenerative braking power via the electric motor 

2. Starts the engine to provide braking resistance to the driving wheels- similar to low gear on petrol manual car. 

When choosing B the hybrid system will regenerate more energy faster ( this comes with more heat added to the inverter and the traction battery) .
In Toyota hybrids the traction batteries are usually set to remain between  40-80% state of charge all the time . Anything outside these numbers the system will start the engine to either change or discharge the battery to more appropriate levels.
Driving in B will actually trigger these two processes faster and more often and this is why Toyota recommends in their owners manual only to use B in specific conditions and not as your regular drive gear. 
 

What stress does it cause Tony?  It gives a retardation force but a lot less load on the motors (presumably what you refer to as stress) in overrun than it does under power.  This whole thread is full of conjecture and speculation about the way the dreaded B mode works.  If it was capable of damage, they wouldn’t rely on over qualified chumps to control the situation, they’d build in some protection and certainly in terms of overcharging they do and it’s easy to observe and hear the system hand off to engine braking when the Battery gets to 100%.  If that graphic is the be all and end all, then there is an imaginary state of over 100% where it turns red and the operator is capable of cooking the traction Battery.  There’s also a point where the owner can damage the hybrid powertrain by overuse of the B mode and negligent Toyota and Lexus designers are inundated by failed powertrains.  Oh wait, no there isn’t, they thought about that and it never happens.  Never.  Not once.

An old fella told me on my wedding day (44 years ago yesterday) “a bit of advice, never let the sun come up on your wrath”, in other words, if you have a row with the mrs, start the following day brand new and I must admit it works.  However, I have noticed, I am least patient in a morning but the forum doesn’t let you edit after a short while so if I let rip at first light (not talking about wind) I can’t back pedal even if I want to.  I’m not having a go at Tony, I like him and I hope we can debate stuff without getting offended but I certainly don’t agree with the author of the thread.  People come on the forum to gather information that helps them decide whether to buy one of these cars and reading this lot could be put off a fantastic car - just about the most reliable in the world.  Manchester has an enormous fleet of taxis.  They are probably 80% Toyota Hybrids with monumental mileages and are driven by people that are woefully incompetent.  If anybody can break one, they can and there are no Fords, Vauxhalls or German cars because they would ruin a taxi company in no time with repair bills.  They don’t care if it’s in B or D any combination at any time as long as it goes and many of them are between quarter and half a million miles.  If I can get any conversation out of them, I often ask if any problems and I’ve never had any of them say other than “no, just oil changes”.  The cars are clearly tired and in need of four shock absorbers, they have lumps on tyres where they’ve been bounced off multiple kerbs, some sound like they’ve got a constant Lancaster bomber escort with the wheel bearings moaning BUT, I’ve never heard a single one with a noisy engine or hybrid powertrain.  Then we get somebody with a 23 model that has decided because he doesn’t understand how the system works but the graphics prove it doesn’t work right, he’s got a demic and Toyota quality is poor.  It’s not a question, it’s a fact.  I admit, I haven’t got a lot of patience for that kind of rhetoric.   😉

My old Prius would only ever get full on the Battery on a long hill near here. It is about 4 miles and you could feel the braking stop as you coasted down the hill in B.

Now back to 12v battery. 
If you have weak 12v battery but still able to start and drive , the hybrid system may get loaded as the low 12v battery requires more time to get recharged and the system will need more energy from the hybrid battery, which will need more energy from the engine.
Even with good soc the engine will  kick in more often and remain on for longer time when the hybrid battery is extra loaded like in these specific situations, low 12v battery, AC working hard to cool down cabin or when outside weather is very hot or very cold. The hybrid system will monitor these variables and turn on engine more often to preserve your hybrid battery and extend its life.

I agree that with low 12V Battery the DC-DC converter should do extra work and drain more energy from traction Battery, but I don't think that this bigger request could cause the always on ICE situation.  I expect that it may cause more frequent ICE starts but not a no EV behavior.  Moreover when this situation happens the SOC level could reach the top. If 12V recharge is so power hungry it should not happen.

I don’t think the traction Battery will flinch at charging the 12v Battery but it will start the engine if the climate control is on. I never turn mine off and as expected I get the engine running accordingly.  It’s by design and I certainly ain’t running round with it off just to stop the engine running.

Well I definitely don’t feel offended or anything, particularly from Don, he is my best friend here 😊.  Although we may disagree here and there or have different view and opinions on certain things, but this is how the truth is born, right.
A 44 years since wedding, congratulations, I am just one month and a half short of reaching 44 years old myself, so I still have what to learn from you guys, and I respect each and everyone’s opinion. 

Now about the cars and expert opinions - I am not an expert or officially trained mechanic, I am simply a Toyota hybrid owner who drives and maintain his own car.
I used work in largest Prius fleet in London 2012-2015
I am not a taxi but I do drive similar mileages and I choose my Toyota hybrid specifically for this job.
Every day I come here and right something about cars is based on driving experience, most members who follow they know me, every day is another 200 miles to the total daily counter.

“The hybrid system will be unnecessarily stressed if we constantly drive in B”- this is written in my handbook, what stress could be, it’s obvious to me and this is heat in the Battery itself and in the inverter. Both has cooling systems so not a risk of anything, damage or whatever, it’s just no needed to be and more heat means less efficiency. 
You can drive a hybrid as you wish, even in N neutral up to the max speed limits of the car 115mph . People says don’t do it you will damage the transmission, well I did it many times at 70mph when was looking for vibrations issues, so no damage was done. I have gone through most common Toyota hybrids eventual problems or issues, a long list to write about, but few of these including hybrid system malfunction, egr blocked, 12v Battery replacement, hybrid Battery replacement, etc , I know my car pretty good as I did on it over 235k miles just by myself, driving and maintaining. I would say these are very good cars, probably the best available at the moment.

I’ve got the S selector in the Lexus which it basically gives the option of using with no restrictions that I can find.  I use it all the time and today again I forgot I’d used it for a big hill and drove most of the way to work (23 miles).  I use it as a retarder for hills almost every time I’m out.  When I knock it across to S it provides braking with foot off and extra power with foot down.

I am surprised that no one has asked if the car is being driven in PWR, ECO or OFF. I am sure ECO will drive more on the EV when available. The B Mode is on the gear change and so far, bar by accident, I never use it.

My old fella used to say, "don't go to bed angry...stay up and fight" !

And... I often drive in "C" mode.  🙂

[Aldino]

Today I had an appointment at Toyota and they tested my car and found no faults except that the voltage of the 12V Battery is low. At Toyota I was told that the 12V Battery is not yet ready for replacement and I should leave the car in P or drive so that it can be charged by the hybrid system. The technician told me that the engine on the Yarissa Cross often starts when the voltage in the 12V Battery is low.

Yaris Cross 2023
My Yaris Cross is 4 months old. For the last few days, the first 15 -20 minutes does not turn on the EV mode,just drive on gasoline engineEV mide just turn on if stop on traffic lights. The hybrid battery is often 100% full, which is not good. Does anyone know what can cause this phenomenon.The weather is warm and the heating is off. Im in Germany

as others have said dont worry about it ours does the same. In winter as its colder the EV wont kick in for a while until things are up to temp. I even find it also then uses EV a little less in winter then summer. Like wise even if it is summer but early morning it still takes a while to kick in. But if you take it out midday when its hot you can drive straight away on EV as its all up to temp because of the environmental temp

The Carista app supports Toyota Yaris features/functions. Why would you want to use it while driving?

[TonyHSD]

Yes you can turn on Carista and use the app to monitor live data. Other apps to look into hybrid Battery and 12v Battery are hybrid assistant , Dr Prius . With Carista app full paid version you can do different settings, lights, dings, seat belts , locks etc
