BYD Han AWD Mk1

The 15.6-inch rotating DiLink infotainment screen can experience sporadic reboots, slow cold startup, and CarPlay/Android Auto disconnections. When the screen freezes, climate control, reversing camera, and navigation become temporarily unavailable. BYD addresses many issues through OTA updates, but some owners report new bugs introduced with updates. A soft reset (hold volume down for 15-20 seconds) usually resolves immediate freezes. Factory reset via System > Version > Factory Reset is the last resort. Most fixes are covered under warranty, though diagnosis may cost around €70-180 at a dealer. The issue is widespread across BYD models and improves with successive software updates.

The 12V battery powers essential electronics including door locks, lighting, and computer startup before the main high-voltage system activates. Certain software modules or the V2L adapter's control module can fail to enter low-power sleep mode after shutdown, causing parasitic drain. Owners report the BMS does not aggressively recharge the 12V from the main battery, and maximum charging voltage (13.8V) is below ideal absorption voltage (14.4-14.8V). BYD has released a firmware fix that increases check frequency, but some owners still experience issues. Replacement with an AGM or LiFePO4 12V battery costs around €150-280. Avoid permanent OBD accessories that prevent sleep mode.

The Han uses flush electric door handles that retract into the bodywork. The electronic mechanism is prone to malfunction in cold or wet conditions, with reports of handles failing to extend when approached or unlocked. In winter, ice formation around the handle pocket can prevent operation entirely. BYD's owner manual suggests gently shaking the handle or checking door lock and battery status. If the mechanism itself fails, replacement involves electronic components inside the door and typically costs €200-600 per handle depending on labor. China has announced a ban on concealed-only door handles from 2027 due to safety concerns. Applying silicone spray to handle pockets before winter can help prevent freezing.

The Han's DiPilot ADAS suite uses cameras and radar that occasionally produce false warnings, overly cautious lane-keeping interventions, and night vision halos. After windshield replacement or front-end work, a full static calibration is required (€240-520 at a certified center). Dirty sensors are a common trigger. Software updates improve behavior, but some owners report persistent false braking events. Always ensure cameras and radar housings are clean. ADAS calibration requires specialized BYD diagnostic equipment, which may not be available at every workshop.

Some owners report the CCS connector lock actuator sticking, preventing cable release after charging. The actuator reset or replacement costs around €180-420. Additionally, the Han's LFP battery is more temperature-sensitive for DC charging than NMC chemistry. In cold conditions (below 15 degrees C), DC charging may be limited to 30-50 kW even at a 150 kW charger. Pre-conditioning the battery via navigation route planning helps, but the Han's 120 kW peak DC speed is already modest for this segment. The issue is partly inherent to LFP chemistry rather than a defect.

Heavy reliance on regenerative braking means the mechanical brake pads and discs see little use, especially in city driving. This causes disc surface rust and pad glazing (vitrification), leading to squealing, reduced effectiveness when needed, and uneven wear. Symptoms include metallic noises, spongy pedal feel when cold, and prolonged stopping distances. The fix involves deglazing or replacing pads and discs (€140-380 for a set). Regular controlled hard braking on safe roads helps maintain disc condition. Some owners switch to lower regen settings periodically to exercise the mechanical brakes.

The European Han AWD comes with a 6.6 kW onboard AC charger as standard (optional 7.4 kW upgrade), which is notably slow compared to the 11 kW or 22 kW chargers found on competitors like the BMW i4 or Mercedes EQE. A full home charge from empty takes over 12 hours. If the onboard charger unit fails, replacement costs are in the €500-1,500 range depending on the unit and labor. This is a rare failure but worth noting given the limited independent repair options.
