Xiaomi Auto Releases Maintenance Costs and Retractable Roof Warranty Details for Pengcheng Series

On the evening of September 15, 2026, Xiaomi Auto released Episode 290 of its "Q&A with Fans" series, disclosing maintenance costs for the Xiaomi Pengcheng model, cleaning instructions for the retractable roof canopy fabric of the N90 Max Explorer Edition, and the warranty period for the retractable roof compartment. The Xiaomi Pengcheng is a range-extended electric vehicle featuring a dual maintenance system combining "pure electric + range extender." Maintenance for the pure electric system covers the air conditioning system, the triple-electric system (including thermal management cooling and inspection of the power battery underbody protection), chassis system (including brakes, suspension, and tires), full-vehicle electronic/electrical and safety components, and routine body and interior upkeep. This service is scheduled once every year or every 20,000 kilometers, whichever comes first. The range extender system adds the following items to the pure electric system’s maintenance: engine oil and oil filter, range extender air filter, spark plugs, and range extender coolant. Specifically: - Engine oil, oil filter, and range extender air filter require servicing once every 3 years or every 30,000 kilometers of range extender operation after the initial service. - Spark plugs are serviced every 40,000 kilometers of range extender mileage. - Range extender coolant is replaced every 6 years or every 120,000 kilometers. Regarding maintenance costs: - The initial service for the N70 Max and N90 Max costs approximately RMB 1,414. - The initial service for the N90 Max Explorer Edition costs approximately RMB 1,444, which includes an additional safety inspection of the retractable roof compartment compared to the N70 Max and N90 Max. - Over the three years following the initial service (years 2–4), total maintenance costs amount to approximately RMB 3,540 per vehicle for the N70 Pro, N70 Max, and N90 Max models, and approximately RMB 3,630 per vehicle for the N90 Max Explorer Edition. Xiaomi Pengcheng also offers a "Worry-Free Service Package." The range extender version is priced at RMB 2,399 per year and includes seven benefits: unlimited complimentary basic maintenance for the pure electric system, one complimentary basic maintenance for the range extender system, worry-free window glass coverage (excluding roof glass and panoramic sunroof, limited to one pane), free paint touch-ups (up to two standard panels cumulatively), in-car network upgrades, on-site tire repair, and vehicle pick-up/drop-off for maintenance (limited to eight uses). In other years, customers may opt for the Standard version (RMB 1,299/year) or Pro version (RMB 1,499/year). The electric retractable roof compartment on the N90 Max Explorer Edition is a factory-installed native feature covered under the vehicle’s overall warranty policy—5 years or 100,000 kilometers, whichever occurs first. The canopy fabric is made of composite polyester material with surface coatings providing water resistance, stain resistance, and UV protection. Xiaomi Auto advises users not to disassemble or clean the retractable roof compartment themselves; if replacement is needed, they should contact a Xiaomi Auto Service Center for professional removal and installation.
