AutoBeta(AutoBeta.net)08/20 Report--

In May this year, Mr. Yi bought more than a year of Porsche Cayenne suddenly caught fire spontaneous combustion, the fire brigade issued a letter of identification, determined that the cause of the fire is caused by electrical circuit failure, and Porsche company identification results said that there are suspected lighter parts in the car, judged as external fire, what is going on? Let's take a look.

According to Mr. Yi, at 11 o 'clock on May 22, the vehicle stopped in the parking lot of a factory in Heshan City, Guangdong Province. Less than 10 minutes after parking, someone informed him that his car was on fire.

Mr. Yi went to check that the driver's seat was on fire. Mr. Yi tried to open the door but couldn't open it. Finally, Mr. Yi and several friends smashed the window and put out the fire with a fire extinguisher. Only then could the fire be controlled. But even so, the seats, center console and roof of the vehicle were badly damaged.

Mr. Yi introduced that he drove for about 2 hours on the day before spontaneous combustion of the vehicle, and the total mileage of the vehicle at that time was 11900 kilometers.

Heshan City Fire Brigade issued an accident identification letter for this, determining that the fire position of the vehicle on fire is the driver's seat, the fire point is the driver's seat, and the cause of the fire is that the electrical circuit fault of the driver's seat ignites the surrounding combustibles.

On May 30, Guangzhou Panyu Porsche Center pulled the accident vehicle back to the store.

On June 4, Mr. Yi signed an agreement with the Porsche Centre to dismantle the vehicle and then handed it over to Porsche China technicians for identification.

On July 23, Porsche's appraisal report came out. According to the report, Porsche team found a part containing metal spring under the seat during the process of removing the seat. It was judged that the part did not belong to the car body part, indicating that it was likely to be part of the lighter, and compared with the compression-ignition lighter, the metal part was found to be consistent.

Porsche China therefore believes that the cause of the fire was not a fault in the vehicle's electrical wiring, but an external cause, unrelated to the vehicle's own oil and hot components.

Such identification results let Mr. Yi laugh and cry, Mr. Yi said, He usually do not smoke, How can there be a lighter in the car, And is in the vehicle inspection two months after the suspected lighter situation.

On August 19, the relevant media contacted a marketing manager of Porsche Center, who said that Porsche China attached great importance to the incident, but the appraisal result was different from the certificate provided by the fire brigade. For this, the company was still negotiating with Mr. Yi to find a mutually satisfactory solution, but it was unknown when the solution would be given.

In addition, as to whether Mr. Yi's failure to open the door when putting out the fire is a design defect, the marketing manager said that the specific reason needs to be explained by Porsche technicians, which cannot be answered at present.

On the evening of August 19, Mr. Yi negotiated with Porsche Centre again, and finally both parties reached an agreement to replace Mr. Yi with a new car of the same model, which was finally resolved.

The investigation found that Porsche recalled vehicles in June because of the risk of fire, but the recalled vehicles were not Mr. Yi's Cayenne models, but Panamera models.

According to the announcement of the National Municipal Administration, Porsche recalled some imported 2011-2016 Panamera series vehicles manufactured between November 1, 2010 and September 13, 2016, and the number of recalls was 42070.

The reason for the recall shows that moisture in the air may penetrate into the interior of the control unit due to insufficient tightness of the control unit of the air conditioner blower regulator. When the moisture condenses into water droplets to a certain extent, it may cause failure and short circuit inside the control unit. In extreme cases, the risk of fire cannot be ruled out, and there is a potential safety hazard.

Porsche China said that since June 24,2019, free inspections have been carried out for vehicles within the scope of the recall, and temporary sealing strips and relays have been added to the air conditioner blower regulator control unit according to the inspection results to reduce the risk of short circuit in the control unit. After the recall is officially implemented on October 7,2019, Porsche (China) Automobile Sales Co., Ltd. will replace the improved air conditioner blower regulator control unit free of charge for defective vehicles within the recall scope to eliminate safety hazards.
