QUOTE(Boy96 @ May 5 2025, 07:22 PM) This one isnt a dead 12v issue. SC still checking actually so lets just wait for result. Thailand got few cases like this where the high voltage cables got chewed by rodents which resulted in similar thing happen. Car goes into emergency mode and shuts down . From the OP, BYD SC stated it was the 12V battery issue,....... Pada 4 petang mereka memberitahu kereta kami mempunyai masalah bateri 12V dan memerlukan masa beberapa hari untuk membaik pulih dan melakukan pemeriksaan. ...
Pada 5 May, mereka memberitahu saya bateri 12V perlu diganti kerana 'low voltage'. Agak terkejut juga kerana kereta ini baru berusia 10 BULAN dan sudah mengalami masalah bateri. Kos penukaran bateri pula RM418 dan tiada warranty kerana kereta sudah lebih 20,000KM. Persoalan seterusnya, kenapa tiada sebarang amaran atau warning dan kereta terus brek mengejut, mereka menjawab, memang TIADA AMARAN atau indikasi jika bateri 12V bermasalah! . |

. Fyi, ....... https://inf.news/en/auto/6af8730a4a0fd35604...1fe3ea6be7.html - The BYD Dolphin, known as the electric version of the Fit, has frequent quality problems. Is it the main reason for the car sea tactics? - 5 May 2025 .... Since last year, there have been reports from Dolphin owners that the car has a power system failure. In simple terms, the power system failure is a stall, the car loses power and cannot continue to drive.
After the Dolphin stalled, the car owner tried to restart first, but after restarting the Dolphin, the car owner hung up the D gear but still showed a power system failure and automatically jumped to the P gear. After repeated attempts, the Dolphin finally declared a strike, in the middle of the road. anchor.
In the end, the owner of the car said with a lot of self-deprecation that it is fortunate that it is not the rush hour. This is indeed the case. If you encounter this situation during the rush hour or on the highway, the sudden stall of your own vehicle is bound to trigger a series of chain reactions, and the consequences are unimaginable. What a terrible thing. ... P S - "car sea tactics".? = .? flood the market with new models every year.? = BYD can tidak-apa about providing good after-sales service to old models since their latest yearly new models are selling like hot cakes in CCP China, eg selling by the tens of thousands yearly.? = pakai buang. .

QUOTE(Boy96 @ May 5 2025, 09:08 PM) No ah, happen to me twice on Volkswagen before.. alternator died on fast lane car shuts down and engages EPB. Had to dolly up tow truck . ???? . AI Overview
No, Volkswagen cars do not typically engage the electronic parking brake (EPB) automatically when the alternator fails. While the alternator is critical for charging the battery, an alternator failure does not directly trigger the EPB. Instead, a failing or discharged battery, which can result from an alternator failure, might cause issues with the EPB.
.

No, Volkswagen cars do not automatically engage the Electronic Parking Brake (EPB) when the battery fails. If the battery is dead and the EPB was already engaged, it will remain engaged. However, if the battery is dead and the EPB was not engaged, it will remain disengaged because the electrical power is needed to actuate the brake into the set position. Some Volkswagen vehicles have a manual release mechanism for disengaging the EPB in case of a dead battery. . |

QUOTE(Boy96 @ May 5 2025, 10:10 PM) The service SA didnt communicate properly la The actual case is still under investigation. But from overseas (thailand) owners group, when this happen, there is an electric high voltage fault. So the system shuts down to protect the electrics. There is no emergency braking, just exaggeration due to panic and regen braking when its slowing down to a stop. It just entered limp /fail safe mode so the car is undrivable anymore despite in D. The SA ask to replace the 12v since it has been drained whilst at SC, they could've just charged it first in order to start diagnostic, not sure why they ask to pay, easy way out i guess . ???? https://www.reddit.com/r/BYD/comments/1j0fr...system_failure/ - r/BYD, 2 mo. ago

Quite possibly the 12V battery dead or too low. I had this twice. Call BYD road assistance.
Or jump start it.
On the picture you see what I saw. After the road assistance jump started my car it was all fine again. . This post has been edited by lurkingaround: May 5 2025, 10:26 PM |

I often see this kind of failures at Facebook groups. The common cause is that the 12V battery connections are loose, many of them say that tightening the connection fixes the problem. Try it

Locate the 12v battery and pull the cable (edit: disconnect the battery). While you’re there check the battery voltage level.
Most common faults I’ve seen (anecdotally) is 12v battery failure. . |

QUOTE(DogeGamingPRO @ May 6 2025, 10:37 AM) Not emergency brake, just motor lose power and cuz EV motor so instead of cruise it just decelerates, but probably to the driver felt like emergency brake cuz stopped abruptly and can’t move The 12v controls the connection between the main battery and the motor, so when 12v gone then motor also will lose power from main battery . After complete power shutdown, there is also regenerative braking to bring the EV car to a fast stop, ie not emergency braking via the brake discs. . |

Most common faults I’ve seen (anecdotally) is 12v battery failure. . . Also, "Power System Failure" that shuts all power to the EV car, can also result from issues with the high voltage system or traction battery. . |
