David I have one fitted already but its  about time Toyota showed this infomation on the car info screen along with the hybrid Battery info.

With regards to the short low Battery warning between speedo and power usage this should stay on the screen until canceled by driver as the few seconds its on you can easly miss it expecily if you steering wheel is blocking it or you looking at the other screen for Battery info.

Toyota recomends if you have a low battery then stay in Hybrid mode ie second key position to give HV battery a chance to charge the 12 volt battery before starting.

This shoud also be programed and shown on the main screen as a timer before you start or press the start button all this is just softwear but dont hold your breath waiting.

I have the one I referred to in the Amazon link across the Battery in the Yaris Cross. It usually shows 12+ volts, but the 'Power' reading can drop quite a bit over the space of a few hours. (I have just checked and it is currently showing 77% - it was 90+% when I parked it at about 4.30pm! The fall off in the 'Power' reading is a lot more noticeable in the Cross than it was in the Corolla - I have no idea why. I agree with you Derek that having the details available on the screen would be a big advantage.

I have not found a way of downloading any information from the app - does anybody know if this is possible? However, you have given me an idea for a new spreadsheet ............🤔

If you using a iPhone just press top volume button and power button at the same time then you have a photo of what was shown on your screensaved in iPhone photos.

I suspect other phones can also take a screen shot then you paste it into other applications.

I have a Samsung Galaxy and the method seems to be similar, but I could not get it to work. I will try, (harder), tomorrow.

Pressing two buttons in a case cover can be tricky (at the same time) try it without the case cover it may help.

Am I right in thinking that you are all accepting of the fault on the Yaris and the C-HR such that the Battery goes flat. I drive 1000 a month living in Cornwall, just driving to the shop is 12 miles but I still had a flat Battery. The RAC are seeing this a lot now, an ex employee of my local dealer says having to put new batteries in is a common occurrence (I had a new Battery installed Monday into my Yaris cross, 14 months old, at the same time another customer, also on decent mileage, having been told they were the first one they had a problem with, was having a new battery but both the dealers and Toyota BG are refusing to accept they have a major problem!

Surely this requires more action from the group. They advertise these Hybrids in urban settings but tell you the car is not upto that type of motoring so officially they are breaking the law on Sale of Gods and Services?

[Max_Headroom]

Why doesn't someone who has had the problem open a thread titled  "My 12v Battery woes" or something similar get all members to post their problems and when the thread gets to a decent length showing this is a common problem send the link to all motoring magazines i am sure they would be interested.

We don't really have any quantitative data about the extent of the problem. Internet forums tend to attract posts from people who have problems but there will be lots of others who have no problems at all. The only evidence we have that this might be a serious problem for Toyota is the reports that the AA and RAC staff are saying they are seeing a lot of flat auxiliary batteries. The dealers are also seeing the problem but they will not cooperate, they will just lie about it because that's what dealers do. So my answer to your question is that I am accepting the existence of the problem and relying on self-help to manage the situation. Frankly at the moment my greatest concern is that the value of the car may be reduced if it becomes widely known that this problem exists and Toyota do nothing to solve it. Most people get cars on some sort of finance but we paid cash for ours so we don't really want adverse publicity.

@Max_Headroom This is that thread.

[Derek.w]

I am only driving 322 miles and thats in the summer less in winter.

No start problems since changing the Battery I presumed no point in asking Toyota for

one I wanted a larger capacity Battery.

Two If Toyota contributed to the cost of a replacment Battery the cost would be about the same as me changing it myself but without the battery capacity I wanted.

Three I can choose the battery MFG I want and its a lot more convinient than goint to the garage.

12v Battery issues aren't only occurring with Toyotas. Hyundais, Kias, Porsches, etc, may all have similar issues. 

The motoring media are aware of the issues already, as are various blogs, forums, etc, and Toyota magazine has published various articles on the same subject. So the information is already in the public domain. 

It isn't new news.

At the end of the day, Toyota Owners Club isn't a pressure or campaigning group. 

Even if it were, for the Club to alert media of the content of any topic, we would need the permission of each contributing member to that topic.

Are they breaking the law?  So called knowledgeable people quote sale of goods and merchantable quality but Toyota and every other manufacturer know what the law is so don’t try that in court or it will cost you a lot of money.  These problems are purely down to a lack of understanding about how hybrids work and I’m not giving in to the entitled protest mob.  I fully agree that the dealers could do more to assess and educate owners but the cars are fine if used right.

Oh no, not another Battery thread, especially one geared towards moanie groanies 😉

[Yaris Hybrid 2021]

Too much is too much. The most unreliable car ever. You never know if it will start or not. But now we have a new car and we hope that the starting problems are over. I don't think I'll ever buy a Toyota again.

[RickyC]

I hope yu're happy with your new car. 

Which car have you choosen ?

[TonyHSD]

Well, people says for some what it is a rubbish, for other it’s a treasure.
The dealer will change the Battery or fix any existing issue if presented and sell the car to somebody who will probably enjoy it as much as some other members does theirs. That’s life.
Hope you have picked a better car and most importantly trouble free.
For reference my best ever and worst ever cars were made by Toyota. 
Good luck 👍

Getting rid of my puma for similar reasons, love the car, just too many faults, hope my New Cross is better,

It's a lock-down car, lots had Battery issues - replace the Battery, also there is a well known DCM issue that causes parasitic draw - It's not so much the car but the dealers and the way they handle it, Anyhoo if you have gone with the DSG i wish you luck

 

The Hybrid driving style doesn't suit everyone

I hope you've choosen to switch from Yaris to Fabia for some more serious reason than the 12V Battery. 

In any case everybody is free to drive the car he prefers, else everyone would drive a Yaris or a Fabia. 😉

Have you had many volgswagen group cars?

[Primus1]

The puma has Battery drain problems too, that’s only a mild hybrid, lots of forum members have had the batteries replaced , improved at first but some were having the same problem, mine had the updates back in January and has also improved things, still get the occasional Battery message though…
