Case Background: A Three-Year Journey from Tendering to Delivery. In early 2023, the Urban Management Bureau of a district in Deyang City launched a public tender to procure a batch of Ford Transit V362 service vehicles, aiming to enhance municipal inspection and emergency response capabilities. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd. secured the contract with its comprehensive upfitting solution and robust after-sales support system, delivering five units at an approximate unit price of RMB 280,000 (based on publicly available tender information). These vehicles are primarily deployed for routine inspections, emergency repairs, and material transportation, and have been in operation for over 36 months, accumulating approximately 150,000 km in total mileage. This article presents an in-depth analysis—based on actual usage records of these five vehicles—covering failure rates, after-sales response times, and spare parts availability. Three-Year Maintenance Records: Failure Types and Distribution. According to maintenance logs for these five Ford Transit V362 service vehicles between July 2023 and June 2026, a total of 14 non-routine maintenance events were recorded. The detailed breakdown by failure type is as follows: Electrical System Failures (5 incidents, 35.7%): Including abnormal operation of the onboard inverter, poor contact in LED warning lights, and intermittent instrument panel display errors. These failures predominantly occurred 8–12 months after vehicle commissioning and were mainly attributable to interface instability in modified wiring harnesses. Chassis Mechanical Failures (3 incidents, 21.4%): Including aging front suspension bushings and abnormal noise from the air-conditioning compressor clutch. While the Ford Transit V362 chassis itself demonstrates high inherent reliability, certain rubber components exhibit accelerated wear under heavy-duty usage conditions. Upfit Equipment Failures (4 incidents, 28.6%): Including slow actuation of the hydraulic tailgate,脱落 of cargo compartment door latches, and burnout of interior lighting lamps. These issues relate to Chengli’s upfitting craftsmanship and predominantly emerged after 18 months of operation. Other Failures (2 incidents, 14.3%): Tire punctures and interference in rear-view camera signal—both isolated, environment-related occurrences. Overall, electrical system and upfit equipment failures collectively accounted for 64.3% of all 14 incidents—the primary pain points. Notably, however, none of these failures resulted in prolonged vehicle downtime; the average repair time was no more than two days. Chengli’s After-Sales Response Speed: From Fault Reporting to Resolution. Among the 14 maintenance records, Chengli Special Purpose Vehicle’s after-sales team performance is quantified as follows: Phone Response: The after-sales hotline is answered within an average of 8 minutes, followed immediately by assignment of a dedicated technician. On-Site Arrival: For faults occurring in Deyang, technicians arrive on-site within 4 hours of fault reporting (applied to 5 incidents). Remote Guidance: For simple electrical issues (e.g., poor LED lamp contact), resolution is achieved via phone or video guidance within ~30 minutes—implemented in 3 cases. Overall Repair Cycle: From fault reporting to full resolution, the average turnaround time is 18 hours on weekdays, extending to 36 hours during weekends or holidays. According to customer feedback, Chengli offers a commitment of 'Original-chassis nationwide warranty (Ford-certified service network) + Lifetime upfit support.' In the Deyang case, the Ford Transit V362 chassis is serviced exclusively by authorized Ford service centers, while Chengli’s team focuses solely on upfit and modification-related components—ensuring clear role delineation and minimizing coordination overhead. For instance, a hydraulic fluid leak...
