We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

Start by checking the after-sales clause in your contract—reputable exporters typically offer 3-12 months of parts support. The usual process: send the exporter a fault description with photos or a short video, plus your VIN and contract number. They will confirm whether it is a warranty case or a paid parts order. For warranty claims, common resolutions are free parts shipped with your next container, or a credit/refund for parts you source locally. Keep all communication in writing. To avoid long waits, ask for the OE part numbers in advance and check whether local dealers stock the same components—many Chinese brands share suppliers. Ordering common wear parts (filters, brake pads) together with the car shipment is the cheapest option by far.

Start with the owner's manual for your exact model and year—it lists the official service intervals and the required fluid specifications. If the manual is only in Chinese, ask the exporter for the English version, or check the manufacturer's website and owner community forums for your region. After the car arrives, do a baseline service even if the seller says it was just serviced: engine oil and filter, air filter, cabin filter, brake fluid check, coolant, and a 12V battery test. From then on, follow the "severe" or "extreme conditions" schedule rather than the normal one—dusty roads, short trips, and hot or very cold climates all count as severe duty, and intervals are usually shorter. Keep every invoice and record. A documented maintenance history makes warranty claims easier and protects resale value.
