Really dont understand why they dont keep spare parts. How many thousand myvi already on the road. This is not a even a continental car. Really pissed off with perodua.

If mine also a fuel pump problem, they should do a major product recall. It's so dangerous that the engine can just suddenly die while driving.

hard to wrongly design a pump setup, more likely they are being supplied with bad pumps. After your pumps get replaced, let us know here if you still experience the problem since if they use a different pump than original and still have problem would indicate a design fault.

A lot of local suppliers are corrupted so have no issues cheaping out and providing faulty parts. I've seen this first hand as part of corruption in malaysia, we really cant make anything here without corruption getting its hands on it. Thats probably why there has been no major recall or announcement, its not considered a safety hazard if your car stalls.

However if the injectors are starved of fuel theres potential to damage them for a huge repair bill. Perodua needs to be quick to investigate, could be either a bad supplier or they just assemble it wrong at factory. Either way transparency helps if you dont want to tarnish the brand, at least if bad supplier can prove and can announce and maintain brand image. If the demand was high, more likely they could've ordered pumps from another supplier, which could be bad pumps.

Thought suddenly car gearbox totally cannot move is exclusive to VW DSG Mechatronic, lol.

german gearboxes are known for smoothness and performance, but not reliability. Even if its bosch i'd question a german car or part. This is very worrying though.

Cant go wrong with a manual.

I've just encountered this issue as well, but mine is funnier. My car is just less than a year old and I rarely drive it so the mileage is quite low. The first time my car died in the middle of the highway, they helped me jump-start my car and told me it was a battery issue. Not even a year and battery die dy 😂 Nevermind, my dad told me to change the battery to a maintenance free one so we voided the warranty on that. However upon checking the original battery, it was still charged at 75% so it was still good.

3 days later, my car died again on a different highway and this time, they told me it was the battery problem again, even after telling them I've changed the battery from their previous recommendation. They did a test drive and didn't believe me that my car could just die like that and kept insisting it was "battery problem" .

When I was just leaving the SC, my car couldn't start AGAIN and this time, I called the mechanic over and rubbed his face in the issue ("See! See! What battery problem?"). Only then did he admit that it was most likely the fuel pump that was causing this issue and when I was shocked on how a car less than a year could have this kind of problem, he just laughed and said "it's common for Myvi already". He also told me it'll take approx. 1 month for JUST THE PART TO ARRIVE IN MALAYSIA while labour would take around 1-2 weeks.

I will be calling up the Perodua customer service to give them a piece of my mind today. So unacceptable.

who did you call for help? No such thing as a car dying while driving in the middle of the road. For an electrical problem to stop a car both the battery and motor which produces DC power have to both die.

One funny thing as well, mercedes had this problem a couple of years ago with the car just dying in the middle of the road while driving laugh.gif .

Its only if cannot start then would the battery be a problem.

Hi there, you seem rather knowledgable and what is your profession, if you don't mind ?

software developer, EEE. So i do know about the computer systems used in cars.

Sorry too burst your bubble but what you wrote is incorrect. A weak battery can and will cause a car to stall too. It happened while I was in the car and it happened to a good friend of mine Cikgu Ali. Cikgu didn't believe initially when I warned him about it when he came to see me about his battery, and sure enough happened to him also while on his way home. Well, I had to help him with my car's battery so that he could drive home. Modern cars with so much electronics in them is now highly dependant on a healthy battery too. 😊

Perhaps the correct question every car owner should ask is when should they change their battery before it dies out ? For some its 80%, for some its 60% and some its 40% State-of-Charge but at stage, one is pushing ones luck a little to far. Penny wise but definately  pound foolish.

Thats the thing, cars dont stall if the battery is weak only if the motor is weak as well in which the voltage of both are too low to supply the required amps. I do know that electronics need the right voltage, but its also to do with amps. Draw too much amps and the volts decrease.

When the engine on, the motor produces DC, ideally at 12V but you do need more volts to recharge the battery so it can go to as high as 15V and is allowed to vary. If the motor is too weak, it will not be able to sustain a good voltage. Thats why the voltage guide for checking battery health for voltage isnt determinate when the engine is on but rather when the engine is off when the battery is fully charged.

If the battery drains too much when the car is off it will mess with the electronics.

But if the car can stall just because the battery is too weak, but the motor is fine, than something must be wrong in the design. Given the same electrical connections, the higher voltage always wins the flow.

Sometimes things plugged into the cig slot can cause interference, especially if they have switching voltage setups like USB chargers (feedback interference back on the 12V circuit from switching 12V to 5V) which can mess with the cars electronics especially if a voltage on the line is weaker.

I believe this fuel pump issue also spread across other car brands such as honda & toyota.

The single fuel pump manufacturer is to be BLAMED for this issue.
Anybody knows which manufacturer did this?
This only happens for late 2018 and the current 2019 car models though.

yup, more specifically this happened a year or 2 before with mercedes in australia, and their customer support was terrible for it, the cars just kept doing that.

Ive not heard it yet for honda and toyota, only merc and recently perodua from here.
