During the warranty period, Qi Jun Company has a valve assembly that can be replaced free of charge.

During the warranty period, Qi Jun will replace the EGR control valve free of charge. Recently, the phenomenon of delayed start-up and difficult start-up has begun to appear. When tested in Dongfeng Nissan 4S shop, the EGR control valve still failed. After inspection, the valve was slightly opened and closed, and it was normal after replacement. Maintenance cost 1600 yuan, the warranty period has expired, and the cost is self-care. According to the last maintenance interval 18 months, the total mileage is 64,000 kilometers, which means that the replaced EGR control valve has only been opened for 18 months, and it will break down after 25,000 kilometers, which is definitely a quality problem. There are still many car quality problems on the internet, and manufacturers should recall this quality problem.
