AutoBeta(AutoBeta.net)01/27 Report--
On January 27, according to the announcement of the State Administration of Market Supervision and Administration, Tianjin FAW Toyota Motor Co., Ltd. and Guangzhou Automobile Toyota Motor Co., Ltd., in accordance with the requirements of the regulations on the recall of defective Automobile products and the measures for the implementation of the regulations on the recall of defective Automobile products, put on record the recall plan with the State Administration of Market Supervision and Administration. Among them, Tianjin FAW Toyota Motor Co., Ltd. recalled some Corolla produced between March 23, 2020 and July 2, 2021, totaling 162301 vehicles. Guangzhou Auto Toyota Motor Co., Ltd. recalled a total of 161614 Leiling cars produced between April 8, 2020 and November 19, 2021.
According to the recall announcement, the manufacturing problems of the engine ignition coils in the vehicles within the scope of this recall have led to a deviation in the size of the level 1 coil support inside some of the ignition coils, and the level 1 coil may be in contact with the central iron core. the insulation between the copper wire in the coil and the central core is reduced. In extreme cases, the engine operation may cause a short circuit between the level 1 coil and the central iron core, which will fuse the fuse and cut off the power supply to the spark plug, causing the vehicle to stall while driving, increasing the risk of vehicle accidents and causing safety risks.
In view of the above defects, Tianjin FAW Toyota Motor Co., Ltd., Guangzhou Automobile Toyota Motor Co., Ltd. will replace the improved ignition coils for vehicles within the scope of the recall free of charge, in order to eliminate safety risks.
Ignition coil, as its name implies, is a device that provides ignition energy. As we all know, if a car can drive normally on the road, it must need an engine drive, and the power driven by the engine comes from the combustion of the mixture in the cylinder, and the energy to ignite the mixture is transmitted by the ignition coil. it's just the spark plug.
Generally speaking, the service life of the ignition coil is more than 100000 kilometers. When the engine is running, there is often tens of thousands of volts of high voltage pulse current on the ignition coil. because it works in the environment of high temperature, dustiness and vibration for a long time, it will inevitably cause aging or even breakage. If it is not replaced in time, it will affect the working performance of the engine. Of course, although the service life of the ignition coil is 100000 km, it is not a fixed replacement cycle, as long as the ignition coil can work properly and there is no obvious aging, it does not need to be replaced.
As for the condition of the ignition coil fault, there are mainly the following situations: 1, the body jitter is obvious in the idle state; 2, the body jitter is obviously changed to the benchmark at 2500, and the body jitter disappears when it is lower than 2500 rpm; 3. The running engine has obvious jitter, which does not belong to the normal engine working state. All in all, when the ignition coil fails, there will be jitter. Of course, according to the recall notice, because the spark plug does not work properly due to problems in the manufacture of the ignition coil, it will directly cause the engine to fail to work properly, and the consequence is that it is possible to lie down on the road and increase the probability of accidents.
With regard to this recall, Guangzhou Auto Toyota Leiling and FAW Toyota Corolla are the best-selling models of the companies. According to the data, the Corolla sold a total of 324763 vehicles in 2021, making it the Toyota brand's highest-selling model in China, while sister Leiling sold 227673 vehicles in the whole year, second only to the Carola.
