AutoBeta(AutoBeta.net)07/25 Report--

Recently, Mr. Jiang from Nanjing, Jiangsu Province reported to the Consumer report that his BMW had a collision due to brake failure. In response to the cause of the accident, 4S store staff said there was a delay in braking, while brilliance BMW said it was "the ground is slippery and difficult to brake".

According to media reports, Mr. Jiang bought a BMW iX3 at Nanjing Ningbao Automobile Service Co., Ltd. (hereinafter referred to as "4S store") on April 15 this year. Mr. Jiang had an accident when he was driving a BMW iX3 into the parking lot on May 15 this year. Mr. Jiang reflected to the Consumer report that when he was passing through the speed reducer, he felt that the vehicle did not respond to any brake at that time, and then continued to step on the brake pedal, but the vehicle still did not slow down. finally, it collided with the wall of the parking lot at a corner, but fortunately there were no casualties.

Mr. Jiang said that before the collision, the speed of the vehicle was about 17km per hour, and there was stagnant water on part of the parking lot. "I can understand that the wet braking distance on the ground is getting longer, but it's not enough to hit the brakes without any reaction." Therefore, Mr. Jiang believes that there is a brake failure in the BMW iX3.

After the incident, Mr. Jiang reflected the situation to the 4S store, which denied the claim of "brake failure" at that time. According to a written document provided by Mr. Jiang, the Beijing branch of brilliance BMW Co., Ltd. replied to Mr. Jiang that "according to the video at the time of the incident, the ground was wet and slippery". The braking and steering function of the car is normal. Technically, it is believed that the accident is due to the fact that the ground with low adhesion coefficient can not provide sufficient braking deceleration and steering lateral force for the vehicle. "

The document also shows that the driver had stepped on the brake pedal 3.5 seconds before the collision and DSC had intervened in the work, indicating that the DSC was working normally. However, Mr. Jiang said that this was not consistent with his actual experience. "at that time, I stepped on the brakes many times and loosened the throttle about 10 seconds before the collision, but the car did not slow down. I put on the brakes again about 3 to 4 seconds before the collision. There is still no response. " Mr. Jiang said that BMW did not provide me with detailed and complete driving data, without the support of the data, it was unconvincing to such a reply.

In addition, Mr. Jiang participated in the mediation process with Nanjing Ningbao 4S store organized by the local market supervision department. "the staff of the 4S store said during the on-site mediation that there would be delays in the brakes and there were no quality defects in the vehicles."

On July 15, the person in charge of the Nanjing Ningbao 4S store told the Consumer report that according to the previous survey results provided by brilliance BMW manufacturers, Mr. Jiang's braking and steering functions were normal. "with regard to the questions and demands raised by car owners, we will continue to communicate with car owners, and if car owners want to invite third-party authorities to test their vehicles, we will actively cooperate."

Data show that BMW iX3 officially went on sale in November 2020, with a price of 34.80-387200 yuan. The new car is based on the BMW X3 design, retaining the BMW family design while adding new energy vehicle elements, such as closed double kidney grille, blue trim frame and new style wheels. In terms of interior decoration, the BMW iX3 is consistent with the current BMW X3, which is equipped with a suspended central control screen, a full LCD dashboard and an electronic handle, but also adds blue decoration to the details to show different identities.

It is worth mentioning that the BMW iX3 has been recalled many times. On March 5th this year, BMW iX3 may cause the rotor to rotate over the shaft because the motor motor in the brake booster hydraulic unit of the Integrated Brake system (IB) has incorrect soldering points in the production welding process, so the control system will detect unreasonable position signals and alarm and enter fault mode. At this point, the IB system will lose braking power and only maintain the basic mechanical braking mode. When the vehicle needs emergency braking, the braking distance will be longer than the normal state, at the same time, the vehicle ABS function will fail, which increases the risk of vehicle accidents and has safety risks. Brilliance BMW Co., Ltd. will replace brake booster hydraulic units for vehicles in the recall area free of charge to eliminate safety risks, and unsold vehicles will be sold after eliminating defects.
