2. The starting date of the quality warranty period is the date of invoice issuance to the dealer or end user.

3. The quality warranty service should adhere to the principle of repair as the main principle, and replace the corresponding damaged parts if it is determined that they cannot be repaired. If the problem can be solved by repair, the parts will not be replaced. If the problem can be solved by replacing parts, the assembly will not be replaced. In principle, the method of repairing and replacing parts is adopted to restore the product technical performance indicators.

4. If the vehicle has quality problems, please contact the customer service department of our company in time. For vehicles that need warranty, if the user keeps the factual site or evidence of the quality problem, our company will only bear the cost of accessories and repairs, and will not bear indirect losses and expenses (road maintenance fees, insurance premiums, cargo damage, profits, wages, etc.) other than the quality warranty.

5. After receiving product quality issues reported by customers, the customer service department can directly solve simple problems by phone or WeChat to inform customers to solve them. For complex problems that cannot be solved directly, professional personnel will be arranged to provide on-site services. Customers should actively assist and cooperate. For vehicles with large maintenance workload or high difficulty in on-site maintenance, the customer service department can negotiate with customers to arrange for return to the factory for maintenance according to actual conditions, and the time will be negotiated by both parties.
