On January 27, according to the announcement of the State Administration for Market Regulation, Tianjin FAW Toyota Motor Co., Ltd. and GAC Toyota Motor Co., Ltd. filed a recall plan with the State Administration for Market Regulations in accordance with the requirements of the Regulations on the Administration of the Recall of Defective Automobile Products and the Implementation Measures for the Administration of the Recall of Defective Automobile Products. Among them, Tianjin FAW Toyota Motor Co., Ltd. recalled some Corollas produced between March 23, 2020 and July 2, 2021, with a total of 162301 vehicles. GAC Toyota Motor Co., Ltd. recalls a total of 161614 Leiling vehicles manufactured between April 8, 2020 and November 19, 2021.
According to the recall announcement, due to the manufacturing problems of the engine ignition coil, the size of the 1-stage coil bracket inside some ignition coils has been deviated, and the 1-stage coil may come into contact with the central iron core, and the insulation between the copper wire and the central iron core in the coil is reduced. In extreme cases, the operation of the engine may cause a short circuit in the 1-stage coil and the central iron core, so that the fuse is fused, cutting off the power supply of the spark plug, causing the vehicle to stop during driving, increasing the risk of accidents in the vehicle, and there is a safety hazard.
In view of the above defects, Tianjin FAW Toyota Motor Co., Ltd. and GAC Toyota Motor Co., Ltd. will replace the modified ignition coil free of charge for the vehicles within the scope of the recall to eliminate potential safety hazards.
Ignition coil Ignition coil, as the name suggests, is a device that provides ignition energy. We all know that the car can drive normally on the road, it must be driven by the engine, and the power of the engine drive comes from the combustion of the mixture in the cylinder, and the energy that ignites these mixtures is transmitted by the ignition coil, but the real action is the spark plug.
In general, the service life of the ignition coil is more than 100,000 kilometers. When the engine is running, there are often tens of thousands of volts of high-voltage pulse current on the ignition coil, because it works in a high-temperature, dusty, and vibrating environment for a long time, it will inevitably produce aging or even damage, and if it is not replaced in time, it will have an impact on the working performance of the engine. Of course, although the service life of the ignition coil is 100,000 kilometers, it is not a fixed replacement cycle, as long as the ignition coil can work normally, and the performance is not significantly aging, it does not need to be replaced.
The situation of ignition coil failure mainly includes the following situations: 1, in the idle state, the body shake is obvious; 2, with 2500 turns as the benchmark, the body shakes significantly when it is lower than 2500 rpm, and the jitter disappears when it is higher than 2500 rpm; 3, the engine in operation has obvious jitter, which is not in the normal engine working state. All in all, if the ignition coil fails, there will be jitter. Of course, as the recall announcement says, because the spark plug cannot work properly due to the ignition coil manufacturing problem, it will directly lead to the engine not working properly, and the consequence is that it may lie on the road and increase the probability of accidents.
The recall involves GAC Toyota Ralink and FAW Toyota Corolla, both best-selling models of each company. According to the data, the cumulative sales of the Corolla in 2021 324763 vehicles, which is the highest sales model of the Toyota brand in China, and the cumulative sales of the sister model Ralink are 227673 vehicles in the whole year, second only to the Corolla.
