At the end of the year, the Spring Festival Spring Festival trip was introduced to the agenda early. Owners who are going to drive home also need to start working on the car before a long journey. There are many discussions about such maintenance at the auto forum, and the most frequently discussed posts on "three Yuan catalysis" are the most heated discussions. The same is true of the local forum in Jinhua. This slightly professional word suddenly entered the eyes of Jinhua owners. What is a three way catalyst? What's the condition of maintaining it? The owners who are going to do a good job of car maintenance can pay attention to this problem. On the forum, the three car encountered three yuan catalyst problem, "the car also often appeared engine fault light often bright phenomenon, 4S said oil problem, halfway was flickered to clean oil and oil tank 3000 yuan, or often lights, after the system has been upgraded, to the 62 thousand - mile or so, then how to sell is also a moment will brighten. Finally, it will be bright. Finally, it will be a moment will brighten. Finally, it will be brighter. Finally, it will be a moment to brighten. Finally, it will be a moment.

Finally, it will be bright. Finally, it will be a moment. Finally, it will It is a problem to determine three Yuan catalysis! "In the forum, the first discussion was this post, lauchiwai said, the 4S store said that it could not claim, can only use other ways to help, but 1 months have no news. One car owner, also encountered a similar trouble. He said in his post that his car was bought in 2011, less than 3 years, more than 70 thousand kilometers, still under warranty. However, the three yuan catalytic device is also a problem, need to be replaced, but the 4S store does not claim to be a warranty claim project, "because of the use of fuel in the process of impurities caused by the replacement of the owners can only pay for their own money." Similar melancholy also plagued the owner of the car bought in December xuser56803952010, a few years after a sudden acceleration of weakness, 4S shop to check the same problem in the three yuan catalytic fault, "4S said that because I did not do maintenance in 4S, I should make up 2800 yuan maintenance project can be replaced three yuan." Three cars, the same problem, are three yuan catalytic device out of the state, which is exactly what parts of the car, 4S shop why can not claim? "During the warranty period, we can't get any guarantees. What should we do with our cars?" This is one of the most concerned questions. Zhou Jinhai, Deputy Secretary General of the Jinhua Automobile Exchange Association, said that the main function of the three way catalytic converter is to filter out vehicle exhaust so as to make the final exhaust gas meet the target. In Zhou Jinhai's view, the failure of the three way catalytic converter is more often seen in old cars and too fastidious luxury cars for oil products. "It's easy to clog, need to be replaced or cleaned, and the price is not cheap. The quality is ten thousand or twenty thousand yuan and the average price is four thousand or five thousand yuan." Zhou Jinhai said that the quality assurance of the three yuan catalytic converter is different from the 4S store. For car owners, when can we detect the problem of three yuan catalytic converter? "The accelerator pedal feels bad, the speed doesn't add up, or the smell of smell after driving may be a blockage or problem in the three way catalytic converter," Zhou Jinhai said. Its damage and its own quality is related to the use of the car, usually use less cars, not open the car perennial, or is always low speed driving car easy to appear three yuan catalyst problem, "for example, do not run long distance, usually only open 30~40 code car easy to form carbon." To improve it is not difficult, Zhou Jinhai said: "running a long distance to the high speed, pull a pull car, or a manual gear to hang three, open 60 miles, speed up, can reduce carbon." Zhou Jinhai said that, in view of the current problem of safeguarding rights, the owner of the car did not pay attention to the collection of relevant bills during maintenance and maintenance. When the complaint needed to be raised, it was found that it could not find strong evidence and increased the difficulty of safeguarding rights; and some owners found the car, dynamic force, sound, sound insulation and other problems in daily use. Manufacturers say these problems are within reasonable limits, and there is no uniform definition of standards. Zhou Jinhai concluded that when the legitimate rights and interests of consumers were infringed, they could safeguard their rights and interests through the following five ways: 1. to negotiate and reconcile with the operators; 2. to request the mediation of the Consumer Association; 3. to the relevant administrative departments; 4. to arbitration institutions to be submitted to arbitration according to the arbitration agreement reached with the operator; 5. to bring a lawsuit to the people's court. . In addition, the industry has called for the relevant departments to set up professional vehicle authority identification institutions as soon as possible from the protection of the interests of consumers, so that the contractual obligations of the operators should be raised to the legal responsibility.
