Electrical faults are among the most annoying problems to discover after import, because they rarely stop the car from running. Ask the seller for a live video walkthrough testing each item: all four windows up and down, sunroof open/close, central locking (including with the key and remote), infotainment touchscreen, Bluetooth pairing, all cameras (reversing and 360-degree if fitted), parking sensors, interior and exterior lights, and the horn. Also watch the dashboard during startup: every warning light should illuminate briefly and then go out. A light that never appears, or stays on, tells you something needs attention. Pair this with an OBD scan to catch stored fault codes the seller might not mention. If a feature "only works sometimes," assume it is broken and price the repair into your offer.

Currently, in most developing countries, there is a severe lack of deep repair capabilities for the three electric systems. We recommend that B2B car dealers must have basic electrical insulation testing capabilities.

This is a typical case of "secondary damage caused by unprofessional rescue." Many hybrid vehicles require access to "maintenance mode" via engineering computers to allow the water pump to run at full speed for exhaust. We do not bear any moral or financial responsibility for cylinder damage caused by local technicians' misoperation.
