Since the new generation of Corolla was officially launched in June, there has been a gradual recovery in sales. However, recently there have been complaints from consumers that the brake master cylinder of some new Corolla models may have quality problems due to inadequate control of parts and components. According to statistics from China Automotive Quality Network, at least two cases of brake failure due to brake master cylinder oil leakage have occurred. It is difficult for the owner to accept that FAW Toyota dealers do not think that the problem with the vehicle belongs to the brake failure, and only deal with the issue by replacing the brake pump for free instead of returning the vehicle.

China Automotive Quality Network Information shows that the two new Corollas with brake failure are 1.8L CVT GLX-i and one is 1.6L CVT GL-i. The two owners were from Chongqing and Dongguan. Both of them purchased cars at the beginning of August this year. The mileage of the vehicles was about 500 and 400 kilometers respectively. The time and process of the problems were basically the same, both around September 20. First, the warning light was on, and then the phenomenon of car could not be stopped. After the 4S shop detected, the cause of the problem was found to be exactly the same: the brake pump leaked.

Mr. Zhu, the owner of the Chongqing vehicle, believes that this is a serious safety hazard and requires the dealer to change his car in accordance with Article 30 of the Auto Three Guarantees Regulations. This clause stipulates that the family car product will have a failure of the steering system, failure of the braking system, or cracking of the bodywork within 60 days from the date of the sales invoice issued by the seller or within 3000 kilometers (whichever comes first). Leakage of fuel, consumers choose to replace the home car products or returns, sellers should be responsible for free replacement or return.

According to the report of China Automotive Quality Network, the dealer of this vehicle, Chongqing Wanjia Toyota Motor Sales Co., Ltd. does not admit that the problem with the vehicle belongs to the failure of the brake system and only agrees to replace the brake master cylinder for free. Another car dealer Dongguan East Toyota Motor Sales Co., Ltd. also holds the same response.

Insiders believe that even if the brake master cylinder or the sub cylinder pump is leaking or seeping oil, it is usually slow, and it rarely causes the brake to malfunction. The two new generations of Corolla have brake failure caused by the oil leakage of the brake pump when the mileage is only a few hundred kilometers, which can only explain the serious problem of the quality of the brake pump.

"Brake failure means that the brake system cannot work. The brake pump is an important part of the brake system. If it is necessary to replace the brake system, does it mean that the original system fails?" satisfaction.

In September 2013, the relevant regulations for the introduction of the “Three Guarantees” for automobiles were issued. The relevant authorities issued the “Guidelines for the Judgment of Serious Safety Performance of Household Automotive Products.” The definitions for failures are as follows: Vehicles, main systems or components are in normal use. Due to product quality problems, the complete loss of specified functions or serious degradation of main performance. Specific to the failure of the brake, it means that the basic brake function or the brake assist function suddenly fails, making it impossible for the driver to brake the vehicle according to his or her wishes, and controlling the vehicle to slow down, including sudden failure of the parking brake to make the vehicle The vehicle cannot be braked by itself while parking or driving.

In the two cases received by China Automotive Quality Network, the owner from Dongguan made it clear that when the accident occurred, he was driving from the basement and suddenly found that the brakes were almost gone. He stepped on the vehicle a few times before reluctantly braking the vehicle. . Do not dare to open, can only call the trailer to pull the vehicle to the 4S shop.

China Automotive Quality Network reported that relevant professionals believe that if the vehicle brake pump involved in these two cases is serious and directly causes brake failure, it is fully applicable to the above Article 30 of the three-car package, that is, The dealer should agree to the request of the owner to change the car or even to exit the car.

According to the owner of Dongguan, he had seen relevant contents of the training of the dealer on brake failure in the 4S store. The above clearly shows that the brake failure is divided into two situations: complete failure and reduced braking performance. Why does the brake failure caused by oil leakage from the brake pump of own vehicle be handled by the dealer?

According to the person in charge of the relevant department, there have been very few cases of returning or relocating vehicles since the implementation of the “Three Guarantees” car. Of course, this can be interpreted as an improvement in the quality of domestic cars, but on the other hand, it also shows that many owners do not enjoy their rights. Among these, the owners are not good at rights protection and some car companies have not rationally used, explain the car three bags Terms are the main reason.

At least from the experience of the Corolla owners whose two brakes failed, FAW Toyota’s auto three-bag system was challenged.
