Most leading Chinese brands' car systems support "offline voice commands" (like adjusting temperature and opening windows). However, if recognition fails due to accent or language limitations (only standard Chinese is supported), you can always control it via the physical screen.

Act fast and follow the paper trail you built before buying. First, document everything immediately: take photos and videos of the fault, note the date of arrival and the odometer reading. Most exporters offer a commercial warranty window (typically 15-30 days after arrival) for major components like the engine, transmission and high-voltage battery. Contact the exporter in writing with the evidence, referencing your contract's warranty clause. For minor issues, a common arrangement is that they air-freight the spare part to you or reimburse a capped repair amount at a local workshop. To protect yourself before purchase: get the warranty terms written into the sales contract, including response time, what is covered, and how parts compensation is calculated. Also ask which fast-wearing parts (brake pads, filters, wipers) they recommend buying together with the car, so you are not stuck waiting for a small part from overseas.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
