At present, in the Chinese market, there are not many models using CVT transmissions. Because most of the independent brands are more inclined to drive efficiency, and the cost is not high double clutch transmission.
Among the domestic automobile manufacturers, Chery Automobile is one of the earliest enterprises to start independently developing transmissions, Chery's research and development of transmissions can be traced back to 2003, at that time Chery Automobile established Chery Precision Machinery Company under its umbrella, and its main business is gearboxes. It was not until 2010, that is, it took 7 years, that Chery's self-developed CVT gearbox was mass-produced off the production line.
However, because the CVT gearbox is designed with more consideration for the fuel economy of a car and the traffic conditions of the city. So the CVT stepless transmission is not suitable for intense driving. Because it adopts different steel belt transmission from other gear gearboxes, the CVT gearbox cannot transmit too much starting torque, otherwise it is easy to cause steel belt slipping and accelerated wear. Therefore, at present, Chery only uses the CVT transmission in some compact cars, and does not use it on high-end models.
Recently, on January 27, according to the announcement on the official website of the State Administration for Market Regulation, Chery Automobile Co., Ltd. will recall 146,631 vehicles, involving Models such as The Arrizo 5 and the Tiggo 7. According to the announcement, Chery Automobile will recall some Of the Arrizo 5 vehicles with CVT 19 gearboxes produced from August 8, 2015 to March 25, 2020, for a total of 121,881 vehicles.
Vehicles within the scope of this recall may not have enough clamp clamping force or incorrect position during the assembly of the gearbox cooling tubing assembly, and in the long-term use of the vehicle, the transmission cooling tube may fall off, the transmission oil leakage, fault light is on, and extreme situations may cause the transmission power transmission of the gearbox to be interrupted, and there are safety hazards.
Chery said that it will replace and reassemble the transmission cooling tubing for free for this part of the Arrizo 5 car within the scope of the recall to eliminate the safety hazard.
Chery Automobile will also recall 24,750 Tiggo 7 vehicles of the CVT 19 gearbox produced from May 9, 2016 to December 30, 2018.
It is reported that the transmission cooling tubing of the vehicle within the scope of this recall is insufficient due to structural design reasons, there is a risk of cracking and oil leakage, there will be transmission oil leakage, fault light on the phenomenon, in extreme cases may cause transmission interruption of transmission power transmission, there are safety hazards.
Chery Automobile Co., Ltd. will replace the improved transmission cooling tubing for this part of the Tiggo 7 vehicles covered by the recall free of charge to eliminate safety hazards.
Although Chery recalled the transmission problem, but the author found after investigation, in the professional quality complaint website, the two models of the most problematic is not the transmission problem, in the recall time frame, Arrizo 5 the most problematic is actually the rust problem, and even as many as hundreds of user complaints, are because of the body rust. So much so that users are still complaining about rust at the end of 2021.
In addition to rust, the most complaints from users are the suspension problem, Arrizo 5 has a shock absorber abnormal sound, running deviation and other issues. Of course, the abnormal sound may also be due to the problem of rust, and some parts have a certain relationship with aging. There are also hundreds of complaints from users about the problem of abnormal vibration dampers.
Transmission noise was the third highest with only 108 complaints.
However, objectively speaking, Chery is also constantly improving the products of Arrizo 5, from the 2018 model to 2021, the number of user complaints is particularly small. The most problematic models were mainly on models that appeared around 2017.
In addition to the Arrizo 5, the problem of the Tiggo 7 in the recall time, the most common problem is still the body rust. It seems that the rust problem at that time was a common problem in Chery.
Tiggo 7 had the highest number of complaints in 2018, with 263 cases. Secondly, the number of complaints in 2020 is also relatively large, with 171 cases. In these two years, the most complained about problems in addition to rust, there are also abnormal noise, window failure and other small problems.
Of course, we must encourage Chery To dare to take the initiative to recall the transmission problem, especially the recall of many discontinued Arrizo 5 and Tiggo 7, but at the same time Chery can not ignore these two other problems. In the future, in the process of research and development of new cars, we can solve all problems and provide users with the most reassuring car, which is the most important.
