i hate the trend of adding unnecessary sensor to a car.
1 of my friend, very early adopter of tesla, b4 official Tesla launch in m'sia.
he got unlucky of buying a tesla with faulty door sensor.
the car refuses to drive bcoz detect 1 of the door not closed when it's already closed properly.

ya, the more sensor, the more problem :X

Now let's take it further, what exactly is wrong with the door sensor ? Mechanical or electrical fault ?
*
During the drive, the sensor suddenly stopped sending signals to the ECU or BCM and the car's computers assumed an accident and went into protection mode.

It is the same as Boeing 737 Max 8 and the AOA sensors. When the sensor fails, the MCAS system took over from the pilots and crash the plane.

You got read the article or not first before posting?
The Tesla problem is due to FSD not functioning correctly + user issue. Quoting from your article:
BYD is totally BYD engineering failure. It doesn’t say anywhere that a user should act as a backup to the door sensor nor does make any sense to do that.

Kesian sd. Have to buy back this piece of junk metal..

means Tesla FSD algorithm is still not matured and unreliable. need rat to test it out. in this Tesla case more dangerous.

for BYD case, yes the sensor problem, at least stops safely under 7 seconds. only other drivers need to be beware of these cars.

Aiyoyo pilots must always be able to override any system just like driver must be able to take control of the vehicle in case of an emergency. If a vehicle is designed to make its own decisions without any input from the driver, then such vehicle should not be on the road.

It's plain stupid for such a sensor that was working before to fail suddenly and bring the vehicle to an immediate stop. The sale of such vehicle should be stop immediately and a thorough investigation conducted.

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.
*
The main issue is the car programming how the car react and action when it receives the signal from the sensor. Faulty or not.

In this case, the programming is bad and not mature. The car wasn't fully tested in all situations.

All this Atto car need to be recalled to change the firmware. Otherwise, all this Atto is like time bomb on the road.

The buy back is because the owner has no confidence in the car. And this experience is a phobia for him. I guess he will sell if not buy back.

Sensors have been in cars since 10 years ago. Any ICE with an ECU is sure to have sensors. Just that nowadays cars have more sensors for everything.

Once i had a Proton just lose engine power on the road. Engine management just appear on dashboard and even lost power steering. Lucky was not driving fast and not many cars on the road....

Got but they have 10 seconds to do it previously. When the plane already nose diving, 10 seconds simply ain't enough to disable the system.

Provided you can see them. When such EV blacks out on a dark highway how ? Just saw a video, the carcam travelling on center lane and suddenly it passed a silhouette of a stranded vehicle on the fast lane sudah kena accident without any lights at all. If the carcam on the fast lane, mana tak langgar.

Imagine a stranded EV without any power on the highway and an iCE smashes into it, which weighs more than the iCE. Mampus.

Previous sensors mostly for monitoring but passive.

Now more and more active sensors monitoring the car without the driver's decision making. It's like Skynet taking over your car and stopping as it pleases. Human drivers not allowed to do anything. One day, these cars may reverse the aircon motor polarity and suck all the air out from the cabin.

Humans are not perfect.

So, even the machines they created are not perfect.

Can't imagine if AI begining self aware next time. Due to an imperfect programming, all decision made won't be perfect either.

Moral of the story for Sime Darby , take incidents like this seriously and not try to push the blame to driver in an attempt of trying to escape responsibility.
You can tell they were trying so hard to run away from responsibilities, when they expect the customer to pay for the battery so that they can fix the car.. doh.gif

To /k that is trying so hard to plotek .. don't simply try to blame the driver without understanding what is going on.
Especially those that claim that they manage a large fleet of cars but actually have very little understanding on the electrical system.

I thought it's an feature like the sun roof for maximum ventilation. 🤣🤣🤣🤣🤣

The only lesson that I have learnt is keep my distance from such vehicles on the road.

How on earth such flaw wasn't detected with all the testings that's done before launch ? Macam tiada testing shit aje.

i suspect rush to market as usual plus software stuff that can OTA they are more confident or likely to rush since can update later. But what if something happens before the OTA update happens? that's the problem with these manufacturers...

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 to allow such a simple battery malfunction to cause emergency brake.

Fyi, .......

Gemini AI Overview

Yes, a weak 12V battery can potentially cause door sensors to fail or malfunction. Sensors rely on a consistent and adequate voltage supply to operate correctly. If the battery is weak or failing, it may not provide the necessary voltage for the door sensor to function properly.

Here's why a weak battery can affect door sensors:
- Insufficient Voltage:
Sensors require a specific voltage to operate. A weak battery may not provide enough power, leading to unreliable or inaccurate readings from the sensor.
- Intermittent Operation:
Even if the battery isn't completely dead, it might fluctuate in voltage, causing the sensor to operate intermittently or incorrectly.
- System Malfunction:
A weak battery can also affect other vehicle systems, including the car's computer, which might influence the operation of the door sensors.
- Other Factors:
While a weak battery is a common cause, other factors like wiring issues, sensor failures, or problems with the vehicle's computer can also contribute to sensor problems.

If you're experiencing issues with your car's door sensors, it's always a good idea to have your battery checked and ensure it's providing the necessary voltage.
