2024-25 BYD Sealion 6: clicking or ticking noise from front wheels
In 2024-25 BYD Sealion 6 vehicles, owners have reported a distinct “clicking” or “ticking” sound coming from the front wheels, typically occurring during sharp turns at low speeds (such as parking or navigating roundabouts). While this problem is most common in Sealion 6 Premium (AWD) variants, it has also been reported in Dynamic (FWD) variants. This clicking/ticking is most commonly attributed to faulty Constant Velocity (CV) joints or drive shafts. However, in some specific cases, it has been found that manufacturing tolerances of the wheel rim allow it to slightly contact the brake calliper under load, or the intermediate steering shaft requires tightening.
Depending on the particular cause of the problem, fixes include:
- replacing the affected CV joint or drive shaft;
- smoothing the inner face of the wheel rim; or
- tightening or replacing the intermediate steering shaft.
BYD Sealion 6: intrusive Advanced Drive Assistance System (ADAS) and Fatigue Monitoring
Owners have reported that the BYD Sealion 6 frequently emits loud, high-pitched audible warnings (e.g., “Please drive safely”) or applies sudden steering corrections. Furthermore, the Driver Monitoring System may be triggered by the driver wearing sunglasses or glancing at the infotainment screen. These issues are caused by an overly sensitive camera calibration and software logic that is not fully optimised for Australian road markings or typical driver habits.
While some software updates (such as Version 2.0.0 or later) have refined the sensitivity, many owners manually disable these features in the “Safety” settings menu. However, because these systems often reset to “ON” every time the car is started.
2024 BYD Sealion 6: “floaty”/”pogoing” rear suspension
For 2024 BYD Sealion 6 vehicles, the car could feel “floaty” or exhibit a “pogoing” (repeated bouncing) effect after hitting speed bumps or dips at highway speeds. This could create a feeling of instability for rear passengers. This was caused by under-damped rear shock absorbers and soft spring rates that were designed for comfort over smooth urban roads, but which struggled with the rebound control needed for bumps or undulating regional roads.
BYD introduced an “Australian suspension tune” in late 2025 models and these models do not seem to have this problem. But for affected BYD Sealion 6 models, many BYD dealers now offer a firmware/hardware update to the damping logic if owners raise this issue when the vehicle is being serviced. Some owners, however, have opted for aftermarket shock absorbers (such as Koni Special Active) to provide better rebound control.
2024-25 BYD Sealion 6: 12 volt battery drained
For 2024-25 BYD Sealion 6 vehicles, the car may become completely unresponsive (“bricked”) after being left for a few days, requiring a jump-start or a battery replacement. This is caused by the Battery Management System (BMS), which sometimes fails to engage the High-Voltage (HV) battery to top up the 12V starter battery when the vehicle is off. Alternatively, parasitic draw from the car’s 4G/5G connectivity and app-syncing features can also deplete the small lead-acid battery.
To fix, dealers can apply a BMS software update to improve the charging logic. However, many owners also choose to replace the factory 12V battery with a higher-capacity AGM (Absorbent Glass Mat) battery to better handle the deep-cycle stress.
2024-25 BYD Sealion 6: headlight low-beam alignment
For 2024-25 BYD Sealion 6 vehicles, owners have reported that the low-beam LED headlights have an extremely short “throw”, often illuminating less than 10–15 meters in front of the vehicle, making night driving feel hazardous. This problem was due to incorrect factory alignment of the headlight units, which were often set too low during assembly.
This issue could be partially addressed using the manual height-adjustment dial (located to the right of the steering wheel). For a permanent fix, however, a BYD dealer had to perform a mechanical re-alignment of the headlight housings to ensure the beam cut-off satisfied Australian Design Rule (ADR) standards.
