What are the causes of BYD Han malfunctions?

BYD Han malfunction causes: EV power limitation failure. At least three cases of vehicles stalling due to EV power limitation have been publicly reported. Since the original posts were deleted with no follow-up resolution reports, the actual causes remain unknown. It is speculated that damage to certain modules may prevent motor startup. Another issue involves microswitch failures in vehicle unlocking, likely caused by the vehicle's inability to recognize the remote key. This can be resolved by opening the engine compartment, disconnecting power for 15 minutes, and restarting. For instrument cluster black screens or infotainment system reboots, remain calm and wait for the reboot to complete - normal function typically resumes. These issues are possibly caused by chip overheating or conflicts between the native Android system and certain apps, hence installing too many applications is not recommended. Failures in recognizing large-capacity storage cards are also attributed to the outdated Qualcomm 625 chip. It's advisable to use the official 8GB card instead, though certain brands' 64GB cards may work - check the card slot temperature and verify their durability and read/write speeds. Testing shows formatting large cards as FAT32 enables recognition, but they tend to overheat, operate slowly, and are prone to damage. Center console noises are likely caused by thermal expansion/contraction stress from extreme temperatures, with no apparent solution. Reverse camera green screens or erratic radar alerts represent the most frequent ADAS sensor failures, which may recur even after dealership service, suggesting potential software-related factors.
