12v battery maintenance, issues, etc.

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…

[yossarian247]

It was endless problems with a Skoda which led me to buy my first Toyota ten years ago! Ironically the main issue with the Skoda was random refusal to start, although not Battery related. Two main dealers and a VW specialist tried to fix it and could not find the fault, so I got rid.

[flash22]

i have worked on my fair share over the years, the small turbo engines can be a bit fragile (a cam belt change can run into £700 by a main stealer), dsg has its own issues, no matter the Marque all brands have issues, the Mk4 yaris has sold in big numbers so there a plenty on the roads

if you are changing cars every 2–5 years, most issue will be covered

For me it will be welcome MK4 Yaris 🙂

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

What harm would opening the thread i suggested have done if it was made plain in the OP that it was going to be sent to the press this which would have got round the problem below, owners are rightfully annoyed  they have spent £20,000+ on a car that they then find lets them down if they dont use it regularly and  need to keep charging it as they are worried they are not using it enough and it will eventually let them down.

Maybe you need to become a pressure group as it looks like sod all is going to be done and this issue will carry on.

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.

There are a lot of articles about small turbo petrol engines suffering from carbon build up which is one of the reasons i chose the MK3 when switching from my diesel.

No we don't. 

The Club is largely managed/moderated by volunteers - currently a team of two, including myself.

As we have other parts of our lives to lead, we certainly don't have the time or inclination to change how the Club operates, or devote more resource to managing media contacts, etc.

I also don't think the vast majority of members want the Club to move away from a quite informal place, where members can seek and give advice to others. 

[Derek.w]

A lot of cars had Battery problems because of covid lockdown so replacment Battery were in short supply for a lot of cars.

Just another reason I kept charging my old Battery every week until the battery I was after was back in stock.

IMO calcium car batteries will be a problem in cars :

Decoding the production date of the Turkish battery MUTLU :

https://power.bigbadmole.com/en/akkumulyatory/avtomobilnye/mutlu.html

If I well understood Calcium batteries should be charget with 16V that is avolatge that usually smart chargers don't offer and also internal DC/DC charging circuit works with a peak of maximum 14V.  There's a design flaw?  Charger designed for Lead Acid or AGM Battery but a different Battery technology choosen during car manufactoring ?

Even applying a static 16V low current charge with a normal power supply ( instead than a microprocesor controlled smart charger like CTEK ) I think you should disconnect the Battery from the car because I don't know how much is safe to apply 16V to internal circuits. 

[Dala]

Ever since I found out that I have a Ca-Ca car Battery, I charge the CTEK RECON - 15.8V max - without disconnecting the car Battery and I have no problem.

I know, it's not 16.5V, but better than 14.7V

[Eddie G]

A half hour over 60mph motorway drive every week or so seems to do the trick Battery wise on my 21 plate MK4 drives great, CVT good and 68.7 mpg with touch wood zero problems in the just over a year ownership, will be sticking with Toyota long term but enjoy your new car all same.

I would suggest that media organisations could be contacted directly by anyone wanting to highlight this problem

As said previously, the issue is already in the public domain and has been for over 2 years.

Hi, 

can someone help me please? I replaced the 12V Battery and all electronics seem to work normally, computer starts, radio, AC. 

But I see a lot of warnings on my dashboard and the wheel is blocked. 

Do I need to do something special to reset the self-check routine?

[Dala]

What car Battery did you use?  Again turning it on and off does not help?

I bought Bosch Accu S4 ACCU 12 VOLT 44 AH  

I am going to do a hard reset in the evening: disconnect this accu, wait for 2 minutes and then connect.

But turning the car on/off doesn't help. I read in the manual that the car somehow can remember the state it was in when the accu died.

[MCatPG]

I'm interested in the warranty implications if an owner changes the 12V Battery for a type different to that which was in the car when it was delivered. My inclination would be to get Toyota's agreement before doing this even if I was paying for the new Battery and having it fitted by a dealer.

By the way, I read that Ca-Ca (calcium ion) batteries have exactly the same fault mode as AGM batteries - if they are discharged below 50% capacity they must be fully re-charged immediately or they will be ruined, and even an immediate re-charge may not save them. If they are fully discharged they will lose a significant amount of their designed cycle capacity (the number of times they can be charged and discharged).
