AutoBeta(AutoBeta.net)07/21 Report--

Recently, a M9 owner from Shangqiu revealed to him that he was driving a new car that he had bought less than half a month ago. The M9 had a suspected brake problem in the basement, causing the car to hit a wall, Henan TV legal Channel reported.

The video posted on the Internet shows that the car crashed into the front wall and made a loud noise as it was about to drive to the corner at the end of the garage. The owner told the media that at that time, when he found the vehicle increasing speed, he slammed on the brakes, but the brakes did not respond, and the vehicle finally accelerated and crashed into the wall. From the damaged pictures of the vehicle after the accident, we can see that the position of the headlights of the vehicle was seriously damaged. For the accident, in the video, the car owner also put forward his own request, which is to require the manufacturer to provide the vehicle driving report data.

In response to this matter, it has also triggered a large number of netizens' discussion. Some netizens commented: the speed is obviously too fast, this curve matches this speed, it is estimated that most people will not be able to turn around. In addition, some netizens pointed out: the epoxy floor with water, do not exceed 5 yards per hour, you can not stop.

Subsequently, the 4S store also responded to the incident: it was not the problem with the vehicle brakes, but the accident caused by the slippery ground at that time. At the same time, it also takes out the driving data provided by the manufacturer, and gives an explanation to the data. The final conclusion is that after meeting water, the adhesion of epoxy floor paint is not as high as the normal dry road, and there is no problem with the vehicle.

Subsequently, the official of the question world also commented at the bottom of the video, saying: after the accident, they received the information of the collision of the vehicle and rushed to the scene to assist the traffic police and the owner of the car. On the same day, the epoxy floor of the underground garage was wet and slippery, and the maximum speed when the vehicle entered the underground garage was 36km/h, and braking was carried out when it was about 15 meters away from the wall, and finally the vehicle hit the wall with 15km/h. According to the background data analysis, the braking system and steering response are normal, and no product quality problems are found. In order to ensure driving safety, when driving in a slippery garage, you should strictly follow the garage warning signs to slow down and avoid slamming on the brake and steering wheel.

It is understood that at present, most of the underground garage floor because the epoxy floor can have dustproof and moisture-proof, but also conducive to the advantages of cleaning, all choose to use epoxy resin for paving. But it is worth mentioning that the epoxy floor is mainly composed of an organic material called "epoxy resin". When stagnant water falls on the epoxy floor, a water film similar to water pouring on the oil will be formed, which will greatly reduce friction, so this is also the main reason for many vehicle accidents on the waterlogged epoxy road surface. Normally, when driving in an epoxy floor with stagnant water, you must control the speed below 5 mph in order to ensure sufficient braking distance and avoid accidents. The maximum speed of the car owner in this accident is 36 mph, which really greatly increases the risk of an accident.

In fact, in recent years, when many vehicles are driving on the slippery epoxy ground, the speed is too fast and urgent to make strong braking, which will lead to too fast tires to slip and unable to stop the collision. Data show: M9 is a flagship model of AITO, launched at the end of December last year, positioning large-scale SUV, a total of 4 models, the price range is 469800-569800 yuan. The latest sales of the M9 were 16525 in June, compared with 58823 in the first half of this year, according to the data.
