Take Hyundai Motor as an example, its recalls include Yaxinte produced in 2012-2015, Yazun produced in 2012-2015, Elantra produced in 2011-2015, Shengda produced in 2013-2015, Feisi produced in 2012-2015, and so on. It is understood that the three models with the most recalls are Hyundai Elantra, Kia Solanto and Kia Optima, with a recall number of 777100, 397200 and 383400 respectively.

It is worth mentioning that Hyundai and Kia have different reasons for the recall. There is a hidden danger of brake fluid leakage in Kia, which is still under investigation, which may be due to the problem of hydraulic electronic control unit. at present, there have been 4 fires and 6 heating (smoking, melting) accidents in the brand.

Hyundai is also at risk of brake fluid leakage due to leakage and short circuit caused by ABS anti-lock brake modules, resulting in 21 fires and 22 heating accidents in the United States since 2017. In 2019, Hyundai Elantra models sold in the United States had the problem of overheating of the ABS module, but because the module was seriously damaged and could not obtain the cause of the problem, the Elantra models appeared one after another and the problem was finally discovered in February 2011. the reason is that there is a leakage of brake fluid in the module. In the same year, Hyundai hired a third-party engineering company called Exponent and finally confirmed that the overheating problem may have been caused by a leakage of brake fluid in the hydraulic circuit of the ABS module.

Exponent found that the O-ring used in the ABS module consists of different rubber material formulations determined by thermogravimetric ("TGA") analysis, and that some material formulations used in O-ring rubber may lose hardness over time. In addition, the material may be affected by foreign contaminants in the brake fluid, which may affect the sealing performance.

Hyundai says owners of the affected cars can continue to drive them, but should park their vehicles outside and away from the building until the problem is resolved. The remedy is to use a new ABS module fuse to provide a smaller working current for the module. Hyundai also said that "in accordance with the reimbursement plan submitted to NHTSA on February 24, 2022, the owners of the affected vehicles will be reimbursed for out-of-pocket expenses incurred to obtain conditional remedies for recall".
