Adhering to the attitude of taking charge of the interests of customers, responsible for product quality and responsible for the safety of customers, Dongfeng Nissan launched a recall plan for the 689,000 vehicles with hidden brakes at the end of February. The recall has been launched more than 20 days ago. However, the “China Business†reporter noticed that the doubts about the recall maintenance program on several major automobile quality complaint websites did not decline, but more than 200 owners began to defend their rights on their own. In a vehicle owner rights group, several owners told reporters: “The rationality of the maintenance measures for spraying silicone oil is to be discussed, and it is hoped that Dongfeng Nissan will completely replace the main pump and extend the brake system.†Although people in the industry believe that the brake problem is closely related to safety, car manufacturers will take effective measures for brand considerations. However, the owner does not seem to agree with this statement. "If the scheme of applying silicone oil is reasonable, I hope Dongfeng Nissan can sign a guarantee." However, with the event's fermentation, the 4S shop staff in turn required the owner to prove that the solution for applying silicone oil was not reliable. In the face of disagreements from various parties, our reporter called for an interview with Dongfeng Nissan. It stated that there was no situation in which “the owner of the vehicle questioned whether it would not fall or rise,†and this recall has already passed the company’s strict technical justification. And durability test, judgment method is effective. Brake storage security risks On February 28, 2018, the recall plan for 6,893,301 vehicles of Dongfeng Nissan was officially launched. The vehicles involved were mainly new bluebirds, Xindaida, and Cenozoic generations produced from April 6, 2015 to July 21, 2017. And Sylphy / new Sylphy. According to the defect description made by Dongfeng Nissan, some of the brake master cylinder oil seals in the recalled area may be turned over due to insufficient surface lubrication, resulting in poor sealing, resulting in oil leakage and causing the brake warning light of the instrument cluster Bright tips. In extreme cases, after the warning light is turned on, it will continue to be used. A serious brake fluid leak will result in insufficient braking force. An automotive engineer told reporters that from a technical perspective, the brake risk of Dongfeng Nissan is very serious. “A lot of old cars, when they need to replace the master cylinder or the drum, are in many cases caused by problems with the seal ring. After a problem with the seal ring, the oil leaks into the vacuum, causing the brake force to drop and the foot to become soft. Lack of braking power." "Brake-related problems are usually closely related to safety and therefore very important. I believe that manufacturers will never take lightly on the issue of braking." Xu Haidong, assistant secretary general of the China Association of Automobile Manufacturers, said. In this regard, Dongfeng Nissan said that in accordance with the national regulations of the recall regulations management system, in accordance with the vehicle recall procedures, all relevant vehicles launched a recall plan. It is understood that for the vehicles involved in the recall, Dongfeng Nissan will add a special silicone oil to its brake master cylinder free of charge to prevent the oil seal from turning over due to friction. Replace the oil seal that has been turned over and brake the master cylinder assembly. To eliminate security risks. For newly produced vehicles, improved parts will be used. As for the progress of the current recall maintenance, Dongfeng Nissan told reporters: “The owner has returned one after another and the problem has been properly handled.†Recalling a temporary solution? With the vehicles involved in the recall plan and 4S shop to repair the car, the reporter noticed that the complaints on the major auto complaint websites about Dongfeng Nissan's recalled repair program have gradually increased. On March 21, a new generation of car owners complained on a vehicle quality complaints website: “March 3, 2018, regular maintenance of vehicles, brake masters injection of silicone oil. March 7 on the high-speed vehicle braking The fault light is on, the fault light is still blinking after entering the service area, and it will return to normal after about 2~3 km, but it will appear again on March 9th and 19th, both of which are normal after driving for a certain distance. The brakes of the brakes in the district emergency brakes were fortunate that there were no vehicles ahead." “I don’t know if the car is flawed, but the car has been feeling soft on the brakes until I see the recall announcement. I received the recall message on March 6, but I don’t recognize the program for applying silicone oil. I hope Dongfeng Day The technical report on technical reliability and safety after spraying silicone oil was issued by the production capacity, and the customer service of Dongfeng Nissan stated that it was not convenient to disclose it.†On August 22, 2017, the owner of the 2016 New Sylphy Gento edition was told to reporters. The other car owner who bought the Sylphy CVT Deluxe Edition in December 2016, the car is also in the scope of the recall, according to its description, in the course of the car there have been three occasional brake failure, the most recent occurrence is On March 4, 2018. "But due to an accidental failure, the 4S shop staff did not test the car and said no problem. After the 4S shop reported to the manufacturer, the manufacturer processed it cold, and he answered that I had no problem and could not be repaired. Now the car has been in the 4S shop for three weeks. ." "Safety is no small matter." The owner also told reporters that 4S stores believe that the problem with their vehicles is not caused by the recall. "The brake master pump will not change the pump without leaking oil. Now, I have already sent a message telling me that silicone oil has been applied. The front desk supervisor at 4S also blames me for being too true." The reporters found out that the Dongfeng Nissan Bluebird, Sylphy, and Tiida models all had complaints from owners complaining that Dongfeng Nissan’s plan to add silicone oil to the brake system of the recalled vehicle was unreasonable and “a temporary solution is not a solutionâ€. Some owners believe that to solve the problem, replace the brake master cylinder assembly with all recalled vehicles. Can the brake master cylinder be filled with special silicone oil effectively solve the brake problem of Dongfeng Nissan? "In this case, the assembly will be replaced with caution in the course of maintenance. However, under normal circumstances, special silicone oil and brake oil will not produce chemical reactions, and it is very durable. I believe that Dongfeng Nissan's method of spraying silicone oil should be certified and effective. It was only adopted." The above engineer analyzed said. At the same time, he also pointed out that neither the master cylinder nor the vacuum booster is expensive, and if it is directly replaced, Nissan can afford it. The reason for choosing to spray silicone oil should have been durability analysis. "Japanese companies have a perfect process for durability analysis. This program should have no problem in general." In Xu Haidong's view, for the recall plan, consumers themselves will have a taboo mentality, and will also pay more attention to the hidden dangers of the car. If the manufacturer has only a short-term, untestable solution to the safety hazards of the car, the problem will be difficult to eradicate. From the perspective of its brand, manufacturers will certainly consider it well. In response, Dongfeng Nissan told reporters that the method of spraying silicone oil used this time can ensure the lubricity of the surface of parts and effectively solve the problem of oil seal lubrication. At the same time, the silicone oil used in this recall is a special low-molecular-weight silicone oil. It has no volatility and therefore has a very long life. It ensures the lubricity of the surface of the parts and prevents the oil seal (sealing ring) of the master cylinder of the vehicle from turning over. "This project has passed our rigorous technical demonstration and endurance test. The judgment method is effective and effective." Main models affect geometry It is worth pointing out that among the models recalled by Dongfeng Nissan, both Sylphy and Tiida are Nissan's best-selling models in China. In particular, Sylphy, the sales of Dongfeng Nissan's various models have been far ahead. According to the statistics of sales monthly reports disclosed by Nissan Motors official website in China, the cumulative sales volume of the Sylphy series vehicles during the period from February to December 2017 exceeded 368,000 units, accounting for over one-third of the total annual sales of Dongfeng Nissan. Will the major recall of the main products have any impact on the sales of Dongfeng Nissan in 2018? "Recall incidents may have a certain impact on auto makers in the short term, but they will have little impact in the long term," Xu Haidong said. Dongfeng Nissan said that Dongfeng Motor Co., Ltd. has submitted a recall plan to the AQSIQ in accordance with the requirements of the "Defective Automobile Products Recall Management Regulations" and "Defective Automobile Product Recall Management Regulations." “We found the problem openly and transparently recalled the relevant vehicles to ensure that all customers can fully enjoy the quality of life that Dongfeng Nissan products bring to them, and will not have a significant impact on the market sales of Dongfeng Nissan in 2018.†In addition, Dongfeng Nissan also indicated that from January to February 2018, Dongfeng Nissan’s terminal sales still maintained a good momentum of increase over the same period of 2017. Data shows that Dongfeng Nissan (including Nissan imported models, including the Japanese product brand models) in January and February 2018 cumulative sales increased by 6.4% year-on-year.
