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 as the local forum in Jinhua, this slightly professional word suddenly entered the line of sight of the Jinhua owners, what is the three yuan catalyst. What's going to happen to maintain it. On the forum, the three cars met the three yuan catalyst problem. "The car also often appeared the phenomenon of engine fault light frequently. 4S said it was oil problem. It was flickered to clean oil road and oil tank over 3000 yuan, or often light the light. After the system was re upgraded, it was no longer to be sold for a moment when it was about 62 thousand kilometers." "Bright, finally determined is three yuan catalytic problem!" in the forum, the first to trigger the discussion is this post, lauchiwai said, 4S store said that can not claim, can only use other ways to help, but 1 months have no news. A Cadillac owner also encountered 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 Mazda 3 in December xuser56803952010 car, opened a few years after the sudden acceleration of weakness, 4S shop inspection of the same problem in the three yuan catalytic fault, "4S said that because I did not do maintenance in 4S, I should make up to do 2800 yuan maintenance project can be changed to three yuan." The three car, the same problem, is three yuan catalytic device out of the situation, this is exactly what parts of the car, 4S store why not claim. Why three yuan catalytic device love the problem "during the warranty period can not be guaranteed, our car how to do." this is the most concern of everyone. Zhou Jinhai, Deputy Secretary General of the Jinhua automotive Exchange Association, said that the main role of the three yuan catalyst is to filter the exhaust gas of the car and make the final emission of the tail gas reach the standard. 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 a car owner, when can you notice a problem with the three yuan catalyst. "The throttle feels bad, speed can't be added, or the smell is smelling after driving, maybe three yuan catalyst plugging or getting out of trouble," 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." In the same situation, how to safeguard rights Zhou Jinhai said, in view of the current difficulties of safeguarding rights, the owners do not pay attention to collecting relevant bills during maintenance and maintenance. When the complaint needs to be raised, it is found that it is difficult to get strong evidence and increase the difficulty of safeguarding rights. Some owners find car fuel consumption and power in daily use. The sound, sound insulation and other problems exist, and the manufacturers say that these problems are within a reasonable range, both sides do not have a unified definition standard, but also cause more consumption disputes. Zhou Jinhai concluded that when the legitimate rights and interests of consumers were infringed, the following five ways could be maintained to protect their rights and interests: 1. to negotiate and reconcile with the operators; 2. to request the mediation of consumer associations; 3. to the relevant administrative departments; and 4. to arbitration organizations to arbitration on the basis of the arbitration agreement reached with the operators; 5. 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.
