How is it that your battery is still kicking long after the warranty mileage of 20,000 kms whereas our friend battery had failed at 10 months or just above the warrantied mileage. It would be good if I have access to that battery in question so that test can be done to determine was it really the 12V battery or is it something else.

If your friends whose Atto3 already clocking 100,000 kms and they are still with the factory battery, this case lagi doesn't make any sense.

A car that takes control away from the driver is a major risk, and not a safety feature.

Imagine you are halfway overtaking on a 2-way lane but the car decides to reduce your throttle speed because it thinks you are driving "too fast" or "too recklessly" due to "lane departure" sensor ?

Oh the friends with 100k mileage have had their 12v replaced at around 60k-65k. But i dont have the readings/report when it failed

I presume your friends didn't use until the battery died correct but when their battery was tested and showed it was weak, they replaced them accordingly.

No, they use until cant start the car

Told you it wasn't the 12V battery. While the whole /k talk about 12V the battery, I was the one who mentioned it cannnot be the 12v battery.

Where is that guy who managed a fleet of cars and claim how he know best and wanted to put me in my place when I said it wasn't due to the 12V battery. Need to dig back the post.

Common sense will tell you that 12V battery is expected to fail and the software algorithm will not be so stupid the allow such a simple battery malfunction to cause emergency brake.

Roman Catholic :- It's all the driver fault for not not changing the battery. If the driver have change the battery despite no warning , this would not have happen.
                           There's nothing wrong with BYD emergency braking when battery is low and it is acceptable. The fault lies on the driver for not changing the battery.
                           I know more because I manage a fleet of cars. Yes managing a fleet of cars , tells me that BYD emergency braking is not a safety issue and it is a driver issue.  

What diverting idiot ? The fucking 12V lead acid battery has a limited life span. No point writing further to you obviously you don't understand how the whole fucking electrical system works and you say it's irrelevant. I am already managing fleet of vehicles and I will drop smart asses like you in an instant.

Best answer would be that owner to post an update how is his BYD now after his 12V Low Battery was replaced.

This is an EV, we are talking about.

For ICE, my clients are supposed to listen to me when I tell them to replace their batteries. Those who don't listen and when face problems, it's my fault ?

What I would like to see is battery was still able to start the vehicle but because it wasn't healthy anymore, it died while the car was being driven.

Fyi, .......

So now how? Claim to know electrical system so well , but at the end turned out to be wrong.
Blamed the driver,  and then now turns out not to be a 12V issue which I predicted.

Don't have to reply to that idiot.

The ps is very clear its the battery

So far none. Not even in the big whatsapp owners only group. All just cannot start car

Don't understand why issue happen so many plotektor, when we should be pointing finger at the manufacturer
