Hongqi was originally used mainly as an official vehicle, but in recent years, with changes in the brand strategy, more and more Hongqi cars have appeared on streets and alleys. As a mechanic with ten years of experience, it is essential to learn and understand each upcoming popular model. After persuading my supervisor, I was finally allowed to enroll in a Hongqi specialized repair training. Now, I can say I am quite knowledgeable about Hongqi models. Today, a customer brought in a Hongqi H9. This car has a function where the side mirrors automatically tilt downwards when reversing and return to their position when driving forward, but the customer's car stopped doing so yesterday. Based on my experience, the issue likely involves the door panel's control circuit. I removed the door trim to expose the door circuit board and measured the voltage at each terminal. As expected, I found two terminals with a voltage of 0, indicating the issue's origin. Tracing the wiring, I found a break, likely due to negligence during assembly. After reconnecting the wiring, the automatic mirror adjustment function was restored. I charged the customer 50 yuan for today.
This car features a 2.0T turbocharged engine + 48V mild hybrid system, paired with a 7-speed dual-clutch transmission, providing a maximum horsepower of 252hp and maximum torque of 380Nm. The power performance is abundant, with strong low-end torque in urban settings.
The chassis configuration includes a front double wishbone independent suspension and a rear multi-link independent suspension. The overall tuning leans towards comfort, offering good stability at high speeds and a high level of ride comfort.
The interior design is striking, with a large embedded central control screen and a fully digital instrument cluster rendering a strong sense of technology. The materials used are also very sophisticated, with a high sense of quality.
The maintenance interval for this car is 10,000 kilometers, with the cost of oil and filter replacement around 700 yuan. I suggest the owner replace the transmission oil, brake fluid, and spark plugs at 50,000 kilometers to provide better working conditions for the engine and extend its lifespan, with prices controlled within 1,500 yuan.
Overall, this car's exterior and interior have an impressive appearance, with excellent power performance and a highly tactile ride experience, which adds points to this vehicle.
