Test Drive Task: Navigate to a quiet area and perform a series of gentle stops and one slightly firmer stop to observe the regenerative braking transition. Ensure the handoff between regenerative and friction braking feels consistent and isn't grabbing abruptly.
Check this by: Inspecting the interior infotainment screen response time while parked. Toggle through the drive modes and climate settings repeatedly to ensure there is no lag or screen freezing, which could indicate software optimization needs.
While driving: Listen for any faint rattles from the panoramic glass roof or the boot area over speed bumps. While the Sealion 7 is well-built, checking for cabin noise is a good way to assess the build integrity of the specific unit you are viewing.
Check this by: Cycling through the ADAS (Advanced Driver Assistance Systems) settings. Ensure the lane-keeping assist and adaptive cruise control toggle on/off without persistent error messages on the digital instrument cluster.
Initial chassis inspection and cabin air filter replacement for optimal air quality.
Brake fluid flush as per EV maintenance standards to ensure pedal feel remains sharp.
Full drive-unit coolant system inspection and tyre alignment check to maximize tread longevity.
Check the tyre pressure weekly to ensure you are getting the most range out of your battery.
Keep an eye on the software update notifications via the BYD app to ensure your vehicle features are current.
Wash the underside of the vehicle occasionally, especially if you live near the coast, to keep the chassis in top shape.
Monitor the charge port for any debris; a quick wipe-down ensures a clean connection every time you plug in.
Have the wheel alignment checked every 15,000km, as the instant torque of the RWD motor can lead to faster tyre wear.
Estimated repair costs if issues arise
Because the Sealion 7 has a high-torque electric motor, you might eventually need to budget for premium EV-rated tyres which help with road noise and range efficiency.
In cars of this age, it's common to consider a deep clean of the air conditioning system and filter replacement to keep the interior cabin smelling fresh and the system efficient.
Even in an EV, the 12V battery powers your electronics. If this component needs attention in the future, it is a standard maintenance task to ensure your car starts and communicates reliably.
