I believe the main issue is not about the buy back, but how many cars are still there on the road with faulty sensor. So it’s gonna be a recall? Or there is no way to detect it?

Human lives can gone anytime with this kind of sudden braking at high speed.

Like someone mentioned, maybe there are more serious issue hence the decision to buy back it.

Ayam not a car manufacturer, but very hard for ayam to believe a company want to buy back a whole car all just due to 1 faulty sensor

Again you are creating failure links by yourself

eg:-
Why would 12V battery fail when it is powered by Dc/DC converter at 13.8V. So Inaccurate.
Any electronic door sensor are voltage regulated. So inaccurate.

You can go round and round and repeat your same story and I will counter you the same way.

I also can create stories :-
12V battery fail ---> LCD light flikering ---> I get headache. LOL

Man I can't believe a Christian claiming to be an expert of electrical system managing a "fleet of cars" got himself wrong when he doesn't even know a DC/DC converter is the one powering the whole car up when it is running.
I wonder if he knows that you can remove the battery after the car is running because the alternator is the one keeping the system alive.
LOL, imagine thinking asking a group of people to change battery makes him an electrical expert... LOL.
It's like saying he cooks Maggi mee at home and therefore he's a Michelin star chef. 
And then when he can't counter with facts, there comes the name calling.
Imagine a Christian after their arrogance and mistakes , can't take the ego bruise and resort to sex toy name calling.
Well it looks like even the Christian thing is a facade.
