It is reported that GM is recalling more than 27,000 Cadillac SUVs globally due to hidden dangers in the wheels of vehicles, including over 2,000 cars in China.
Since 2013, there have been a few car companies that “planted†on wheels in China, and various complaints from car owners are often seen in various media. According to statistics, only in early May, Changan Suzuki, Beijing Hyundai, Buick Excelle, Beiqi Foton, Global Hawk and many other automotive brands have received complaints regarding tires . The reasons for complaints include bulging, puncture, and abnormal wear.
However, the status quo is: “Any complaints are made by you. I don’t move.†Auto dealers generally deal with such complaints in two ways: First, tell the owner: your tires have passed the warranty period; The owner of the warranty said: Your tire problem was caused by improper use and you cannot pay.
Is the quality of matching tyres and replacement tyres not uniform?
The complaint cases listed above all refer to the original matching tires for the vehicles. So why are so many supporting tires criticized?
This may be from "this is the same root, quality difference". According to reports, many tire manufacturers provide matching tires and replacement tires, even if the same model, the quality is also different.
Not long ago, the reporter asked the technicians of a domestic tire company whether the quality and technical standards were the same for the tires that were provided to the auto companies and the replacement tires that were sold on the market. The technician's answer was: "It's definitely not the same." Then it was secretive.
The editors later asked the tire companies about this, but most of the interviewees were ambiguous, and some said: "It should be the same." Some are: "Not very clear."
It is understood that relative to the replacement of tires, the profits obtained by tire companies on matching tires have been minimal. Some companies even said that this part of the product "has no profit or even lose money," and the reason why it still maintains this market, but is to "use the auto companies to improve their own visibility."
Can you imagine: "no profit" products, quality assurance it?
Unclear from "not important"
On the other hand, why did auto companies ignore many tire complaints?
According to analysis, first of all, tires are just a set of parts compared to the whole vehicle, and they are easily overlooked parts compared with other parts such as engines. The editor had asked too many consumers. Most of them didn't know which manufacturer and which kind of tire they were equipped with.
Since it is an "unimportant" component, there is no need to pursue too much. Clearly, "controlling costs" is even more important.
Second, the "costs" of car dealers dealing with problem tyres are very low, which on the other hand "contempt" them. In many relevant regulations, tires are classified under the category of “consumer partsâ€, and their warranty period is also shorter—usually 3 months or 5,000 kilometers, and some are not even warranted at all. In this way, many car owners, especially new car owners, will not be aware of the warranty period.
On January 1, 2013, the "Regulations on the Revocation of Defective Automotive Products" was implemented. The media has repeatedly reported that since the tires after-sale problem has "there is a standard to follow." However, the fact is not so simple.
The “Three Guarantees†stipulations of the above-mentioned regulations for automobile matching tires are as follows: If there are defects in the tires of the accompanying equipment, the manufacturer of the automobile products shall be responsible for the recall. However, it does not stipulate what kind of defects appear, how many tires have defects, and who will identify such “defects†in order to meet the recall criteria. Therefore, this provision does not seem to have a substantial effect on solving the various problems that exist in domestic automobile matching tires.
China is now a well-deserved auto country. However, many areas are still in a state of “unclear,†and the “blurry†of matching tires seems to be difficult to clarify in the short term.
