BYD Sealion 5: “Distracted Driver” and “Fatigue” warnings; Lane Keep Assist interventions
For BYD Sealion 5 vehicles, owners have reported that the Advanced Driver Assistance System (ADAS), including fatigue monitoring, is overly sensitive. Specifically, the Driver Monitoring System (DMS) camera on the A-pillar frequently triggers audible “Distracted Driving” or “Fatigue” warnings as a result of the driver checking their side mirrors, yawning or wearing certain types of sunglasses. Furthermore, the Lane Keep Assist system can be overly aggressive on poorly marked roads.
To achieve high ANCAP safety ratings, the safety systems were set to a high level of sensitivity. Furthermore, the infrared camera misinterprets natural head movements as a lack of attention, and the LKA system was tuned for well-marked roads.
Drivers could lower the alert volume and adjust the sensitivity in the ADAS settings on the touchscreen. A permanent improvement, however, requires a BYD service centre to implement a firmware update to recalibrate the camera’s detection logic.
2025 BYD Sealion 5: “12 Volt Battery Low” and “Power Limited” warnings
For 2025 BYD Sealion 5 vehicles, the car may become completely unresponsive (“bricked”) because the 12 volt starter battery has been depleted, even if the “Blade” traction battery is nearly full. This often results in a “12V Battery Low” or “Power Limited” warnings on the dash.
This problem is typically caused by a high “parasitic drain” when the vehicle is locked, or the DC-DC converter failing to adequately top up the 12 volt battery while the car is being charged via a slow AC home charger.
The immediate fix is to jump-start the 12V battery using the terminals under the hood. For a long-term solution, many owners opt to replace the factory lead-acid battery with a higher-quality AGM battery. However, AustralianCar.Reviews recommends that owners get the latest Battery Management System (BMS) software since it has improved 12 volt battery maintenance logic.
BYD Sealion 5: clunking and knocking noises from front suspension
BYD Sealion 5 owners have reported clunking or knocking noises from the front of the vehicle when driving over speed bumps, or when turning at low speeds. This problem has been attributed to loose mounting bolts on the front stabiliser (anti-roll) bar links. A BYD dealer can typically resolve this issue by re-torquing the suspension mounting points and lubricating the bush housings.
Some drivers have also reported the vehicle pulling slightly to one side on the highway, despite low odometer readings. This problem has been attributed to the factory wheel alignment settings being out of specification. This can be fixed by a four-wheel alignment.
BYD Sealion 5: touchscreen lags or freezes; driver settings are forgotten
For BYD Sealion vehicles with the DiLink 5.0 system, owners have reported that the large touchscreen can occasionally lag of freeze, particularly when running wireless Apple CarPlay or Android Auto. These problems are due to software errors related to the “handshake” between the smartphone and the car’s Bluetooth/Wi-Fi module. To address this problem, a system reset can be performed by holding the volume scroll wheel on the centre console for 10 seconds.
Some owners also report that the system “forgets” saved driver settings, such as mirror positions or climate control preferences, after the car is turned off.
For both these problems, it is recommended that owners get the latest over-the-air (OTA) updates.
BYD Sealion 5: power tailgate fails to close completely
For BYD Sealion 5 vehicles, there have been reports of the power tailgate failing to close completely, or it may detect a “phantom obstacle” and reverse direction mid-way. This fault is generally caused by overly-sensitive pinch sensors in the tailgate. Owners can re-calibrate the tailgate by manually holding it at the desired height and pressing the “close” button for five seconds until there’s a beeping noise.
BYD Sealion 5 Premium: driver’s memory seat doesn’t work
For BYD Sealion 5 Premium vehicles, owners have reported that the power seat memory function may fail to return the driver’s seat to the correct position when the driver enters the vehicle. This has been attributed to a calibration error in the seat’s position sensors. A BYD dealer can perform a “hard reset” of the seat module using their diagnostic tool to clear the sensor cache.
