At 1st I thought got door is opened so I cannot lock it then I check all the doors , not all shut tight then I just leave it after that until now still work normally , hmm

manual or auto?
engine was in warm or cold condition?

Probably many have read this explanation from Perodua technical staff himself

Well just to be clear, by just turning off the engine, the steering won't lock. You will just lose power steering and it becomes extremely heavy to steer. Need to remove key from ignition only you can lock the steering which is can only be done manually by the driver.

I am not sure from what you mean by shd. (Any example links would do) I saw some ventilated batteries when I searched google. Maybe I could use a arudino to control the charging when the car's ignition is on (stop once the battery has 12V) and also make sure the current only travels from the car's battery to the additional battery.

Maybe i will just use a battery and charge it manually outside when the charge is low. I need a second one for accesories which run when the car is switched off. (and maybe when its running too, so I can take load of the original battery). The accesories will be custom so there wont be a problem wiring.

The alternator seems like alot of useless work.

yea i guess ESC would help better in this situation. Nonetheless, better tires if u want to drive at higher speeds or DRIVE SLOW. 

I am expecting two different consumption for now 5V 1A and 12V 1A for now. The 5V will have a converter so power will be lost there as well.

This is stupid. Talk complain to the manager or direct to Perodua HQ. I have no problem adding up the balance oil until enough for free replacement. Opened oil will not change in quality even up to 3 years, I read before but there are many opinions out there.

Hi. Would like to know whats the worst thing can hapen if change rim to 195/50 R15 6.5jj. No other mod. No sport spring.

Can anyone recommend where to buy car battery? Plan to change it as it is difficult to start.

Stock rim can change metal tyre cap? (The inlet that pump air into tyre)

Today feel very stress on my gear problem. Once moving from P to R, I feel very hard to move and will feel like startled after able to move to R. Have you all facing the same?? Its happened intermittently usually on the slope place. I'm planing to send my car for checking. Already mentioned before during service, but they said nothing wrong/no need to do anything.

buy aftermarket blade, keep the original blade's steel and use it with your new blade.
