After 12 days of investigation at a BYD service centre, representatives from BYD Sime Motors visited the owner in Melaka to provide an explanation on the issue. While initial assessments pointed to the 12V battery as the culprit, the final diagnosis revealed a different root cause: a faulty sensor located at the driver’s door.

According to the explanation given, the damaged sensor mistakenly triggered the vehicle’s safety shutdown sequence.

This caused the Atto 3 to initiate rapid emergency braking, which activated the hazard lights and bringing the car to a complete stop in under seven seconds. This was followed by a full system power-off.

The car reportedly became unresponsive with the gear in neutral, and the wheels locked, preventing it from being pushed to safety. As a result, it had to be towed with the help of wheel dollies.

The owner has also published dashcam footage, confirming that the car began braking at 00:21 while travelling at 106km/h, coming to a full stop by 00:27. He emphasised that no warnings or indicators appeared before the vehicle took “drastic” action.

While the experience was unsettling, the matter was resolved when BYD Sime Motors agreed to repurchase the vehicle via full settlement with the bank. The owner noted some financial loss from several months of instalment payments but said the decision was made in the interest of family safety. As shared in the previous post, his EV was 10 months old and have clocked over 20,000km.







Similar case overseas (brasil)

good for him because can buy another atto3 at discount right?

Didn't know car will emergency brake if door is opened

Salahkan pintu pulak

faulty sensor at the door also brake? LOL

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.

Gila punye safety function

Illogical to power off and lock wheels

Not scare meh?

Switch to reliable car better

recall inkambing or isolated case? lol

: a faulty sensor located at the driver’s door.

What the fuck? Why so many sensors are directly connected to the car's ability to be used?

wow thats scary man

No viral won't resolve?

FuSa is a bitch causing unintended consequences

so this faulty sensor shit is a disaster waiting to happen.. imagine these modern so called high tech cars now packed with sensors in every corner, one of the sensor go crazy u will risk losing life stopping suddenly in the middle of high speed freeway

Yup that's some regenerative braking going on at 106km/hr to 0 km/hr in just 6 seconds.

this is really stupid and unnecessary move.

nasib baik bukan time corner...lol

Wah ... Really Bei Yan Diu lah lei

Much technology
Very advanced

walauweh, phobia lor, i don't think i still able to drive back the same model or even the same brand ler

my life is not that cheap thou

big loss to him bro. no way he will buy another atto. lol. manufacturer for sure follow that 25% depreciation rules when repurchase his car. he lose big wo in term of monetary

this is lesson to him. dont simply become rat and buy early adopter ev from china

now soyacincau become car review tread and faster updates that Pauline Tang

you are the beta tester sankyu.

if he wants to try dying again, then yes

Not only the driver's life but other road users as well

now i should be alert of this beiyandiu

Isolated case ni
Please don't generalise all Atto3

#doneplotek

I think he also glad to be able to sell back to them,safety more important

so become rat lab for Testla or Beemer/Meseli EV is okay la?

inb4 tesla > all

Ev companies need to be seriously get audited by safety board. Need to check their electrical scchmatics. Im curious how many sensors when go into error start deactivating the car for no reason what so ever.

My ice car if crank shaft sensor rosak to o2 sensor rosak it won't deactivate the car midway driving

I smell bullshit.

Either BYD Malaysia just wanna keep something more sinister under wraps or BYD system architecture has a serious flaw where a non safety critical fault can trigger system shutdown. Even so, no reason to have car totally unresponsive.

We can only hope our authorities can intervene before something worse happens.

During development, all car manufacturers and suppliers must conform to ISO 26262 with regards to electronic components. BYD is not a new manufacturer. So either something is wrong with their architecture or something worse is the culprit. Can’t be a door sensor.

Is this ISO requirement applicable in China?

If it was a faulty door sensor how come this was not picked up by the owner and mentioned earlier in the initial report ?

looks like those who bought is the lab rats now

wait for Atto 4 Ultra Pro Max edition, will have bug fix

Kenot just OTA update kaaa

All are software driven

Serious software bug

Cannot simply slam the brake and shutdown the car just because of a sensor fault. Must have better algorithm to manage data from faulty sensors.

Already say. Avoid china brand cars. No RnD. Just copy paste. But copy also can fail.

Lol retarded so called high tech junk.

My father BMWajunk electrical faulty as shit, doors will auto unlock randomly and lock back when step brake. But luckily didn't randomly kill the car like this CCP junk

buy more cars that's full of electronics and sensors inside

all it takes is 1 sensor

Ah Boy are you still using this same car or already sold?

made in china no good again

Nanti Sime Darby selling BYD pre own with low millage.

The car's computer did not give any visible clues to a door sensor fault but simply shut down the vehicle.

Same car la ayam happy with this car why sell

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

If faulty sensor at door , just tell or give warning to driver got faulty sensor at door

Pusing pusing until cow also can fly

Inb4 LOD coming

BYD thanking the beta testers ler for real life test and improving the vehicle

Later all the Ev fanboy beta testers in /k here come wallop anneh only u know

There is more than meets the eye

So it is not the door sensor is faulty right ? How can a faulty door sensor shut down the entire vehicle that is in operation ?

Automotive is IATF no?

Atto 3 prices going to drop more and I think many people going to dump off their Burn Your Dick Atto 3 car…

The one in this case was just 10 months old, and so fast sensor kaput already…

Did u read the article? SD agree to buy back the car on the remaining hire purchase amount with bank..

I don't think you can detect any sensor fault of any kind, unless you have multiple units of the same sensor with one not reporting the same condition with the other.

For example you have a temperature sensor reporting very high temperature but actually it is faulty, how would the system knows that it is faulty? It is impossible to know that. Unless you have another sensor's reading. If both sensors reporting high temperature, then only the system really knows that you have high temperature. If one is very different from the other, then you have a sensor fault.

Good for them. All byd cars should offer buy back as an assurance.

buy back sounds good on paper but dude lost 10 months of installements and ended up with a life scar and no car

Worldwide recall?

The manufacture can program the vehicle to shut down in any manner if any sensor is faulty. Whether that's a logical step is another issue.

Not bad, atleast byd buys back

jgn jgn, other ev also do this same stunt lol

Detection of a faulty sensor is impossible if there is only one sensor.

If a door is truly suddenly opened when driving then shutting down is a legitimate way to save the passenger. I think they should have 2 door sensors for each door instead of one.

But why buy back if can replace the faulty sensor?

Even if not applicable, if they want to sell internationally, they have to conform.

Cukur. Now we know that the distributor will offer buy back immediately got door sensor problem.

Tesla woso





https://www.facebook.com/share/p/18spa5etRV/

Gila la wei. Conti even engine meletop pon you can replace the engine only.

No need to scrap the whole car lol.

It is so dangerous that replacing the faulty sensor does not cut it but must buy back for safety reasons.

because it is not just faulty sensor? Suck Dick wants to bb coz wants to hide further error by Bei Yan Diu?

No need 2 sensors. Vehicle controller should be able to determine faulty sensor signal through CANBUS.

The issue here is the way the vehicle determined a faulty door sensor as a safety critical issue, which if following the norm, door sensor should just be Automotive Safety Integrity Level A.

ASIL-A components shouldn't cause vehicle to totally shutdown.

So, if it's true that it's due to door sensor, means BYD architecture on handling faulty sensor is flawed.

If it's not due to door sensor but something worse, BYD is covering up.

Not sure how our authorities will handle.

But if this happens more frequently, especially in EU or US, than the authorities will investigate and BYD might need to issue a fix and recall.

Kesian sd. Have to cover up for BYD’s poor engineering.

Maybe manufacturer wants to recreate the same situation for testing.

Noway they will buy byd already la even 50k also wont buy.

As i said many times, china cars have such poor engineering that a sensor in the door can cause catastrophic malfunction of the whole car.

Which stupid engineer designed that sensor?

Byd shud recall n reprogram the sensors systems so tht won't have engine shutdown when faulty or errors

If you have the time, calculate 60Kwh to explosion in joule then find what kind of explosive that matches that energy release. Then realize, that you do not want that kind of energy between your crotch. No i'm serious. Searches like this flags you as terrorist.

Then you will probably think "haiyaa... can one la...".

Then after 1 day of sleep, you realize, thats why they put so many safe guards into an EV. Have you ever thought that they armored the battery is not for puncture but rather energy containment? No?

good lah..at least a closure for owner..no more worry and of this problem

and byd can fix this issue do something about it

ploton da best, only window rosak

If there is a connection issue to the sensor then you can say you can detect no communication with the sensor. If there is no communication problem with the sensor but the sensor gives you wrong data, that couldn't be detected unless you get data from another sensor to confirm.

because this isn't a sensor issue, this is a programming issue
u change the sensor now...it should be fine but the programming part isn't updated

so if anytime in the future the sensor fail again, the same thing is gonna happen again
and maybe worse thing is gonna happen

That wouldn't require any recall, just a software update would do.

True also. But the way the car behaves after a faulty data is the issue here. Door sensor shouldn't trigger abrupt full vehicle shutdown.

First time I hear the car come to full stop with a faulty sensor

This is just insane there are so many sensors in a car and instead of faulty it should go into limp mode ( drivable so u can coast to the side ) and stop safely

The chances are much less than takata airbag killing people.
so dont worry.

Perfect if kidnapped or carjacked. Just open the bloody door and flee for help.

i dont think its just a faulty door sensor..... thats a very very low level mistake that 1 sensor faulty will cause the entire system to shutdown

Buying back the car at remaining bank value is an insult to the car owner, his life at risk, caused trauma and inconvenience, lost of use and also few months of installment lost

Come on, i think they can do better than this

If can wrk via update good, Maybe need plug in,some hardware replacement etc

mb also same.. try driving and open driver door... gear
goes straight goes to P.

Probably too aggressive safety precaution in their programming. I wonder if that's a requirement in their ANCAP certification? Maybe should give user the option to choose whether to just give warning only or shutdown or do nothing.

used BYD will flood the market soon

From this statement already know you are no automotive and safety engineer here.

See if proton does that lol

Hardware recalls may be warranted if more of such devices were found to be faulty, like what happened last year with their power steering fire hazard problem with some of their models.

.
Most likely Ah Boy96 will now drive his BYD Atto 3 below 69km/h on the highway, just in case .....

.

This is /k lah. Not a automotive safety forum. You can berambus to there if you are one such expert.

.
I don't think the Tesla on FSD woso this same stunt.
.

Why should i berambus when i can call you out for tokok here?

Kecian u kantoi again tokok acting like automotive expert.

Already happening due to unsold inventory. Good luck buying ccp cars.

https://theedgemalaysia.com/node/756680

When this Atto3 failed on the fast lane, what was the HV Battery readinga ? I don't remember reading anything about this.
