· Look at the recall of parts related to car recalls in 2014, accounting for 80%

From the perspective of auto parts, the 2014 car recall was another scene compared to the previous year.
According to the statistics of the recall report issued by the AQSIQ Defective Product Management Center, the reporter found that in 2014, China implemented a total of 124 vehicle recalls, recalling 5.0252 million defective cars, including about 3.95 million domestically produced cars. 1.1 million vehicles. Since China implemented the recall system for defective automobile products in October 2004, the AQSIQ has implemented more than 780 recalls involving more than 20 million vehicles.
In the context of the steady growth of automobile production and sales nationwide, the number of recalls and totals of China's vehicles in 2014 have decreased compared with the previous year, but the reasons for the recall are more diverse and complex, and with the global procurement of auto parts. The expansion, as well as the introduction of auto parts into the recall system regulations, is likely to have more cases of multiple automakers implementing recalls due to defects in the same auto parts.
According to the National Defective Automobile Product Recall Integrated Management Information Platform, the classification of automobile defect information collection is counted in ten categories (engine, transmission system, braking system, suspension system, steering system, electrical equipment, body, airbag and seat belt, Among the tires and wheels and additional equipment, the number of defective vehicle recalls related to engines, airbags, seat belts and suspension system components accounted for more than 80% of the total annual vehicle recalls.
â–  Engine-Recall The most complex engine and related component assemblies are the most complex automotive component systems. Last year, more than 40 reasons for the recall related to the engine involved the engine itself, fuel supply system, cooling system, ignition system and new energy components. The total recall amounted to 2.153 million units, accounting for 42.61% of the total recall.
A fuel pump flange return pipe bracket, so that more than 900,000 cars of 10 independent brands such as Brilliance, Great Wall and Chery are “affected”. In the last two months of 2014, two batches of Chinese auto companies jointly announced the recall of more than 860,000 vehicles, mainly due to the design and manufacturing problems of the parts supplier and the Automotive Electronics Co., Ltd. or the fuel pump flange return pipe bracket cracking of the vehicle. , which causes fuel leakage. In August last year, the SAIC passenger car recalled 58,000 Roewe 550 cars due to the same problem or the fuel pump flange return pipe joint crack and fuel leakage.
Any excellent engine technology can not be tolerated, and German BMW, which is often talked about by consumers, has to recall all of them due to a little negligence. In April last year, BMW (China) Automobile Trading Co., Ltd. due to the design of the fixing bolts on the engine variable valve timing mechanism (VANOS), during the operation of the vehicle engine, the fixing bolts may loosen or even break, thus recalling the inlet 1 The system, 3 series, 5 series, 6 series, 7 series, X1, X3, X5, X6, Z4 totaled 138,500 units.
There are many quality problems in the fuel supply system components, and it also reflects the defects of the vehicle management process. Shenlong Automobile was mixed with a small number of unqualified multi-function valves during production, which caused cracks in the multi-function valve casing during the use of some vehicles, which caused the recall of 162,900 domestic Citroen Sega and Peugeot 307 and 408; Chang'an Ford's performance in the last year was due to the failure of the vehicle's refueling hoses and filler hoses. The long-term use will cause cracks and recall 191,700 Foxes.
Last year, the hybrid Toyota Prius was damaged due to incomplete vehicle control procedures, which caused damage to the inverter of the hybrid system and recalled 3,210 vehicles. The British luxury car brands Jaguar, Aston Martin, Luster, Land Rover have recalled different scales due to quality or installation problems of parts such as charge air coolers, accelerator pedals, oil cooling hoses, fuel injectors.
■ Airbags that drive the whole body and the whole body The safety awareness of Chinese consumers' car use is gradually improving, and whether the airbag configuration is perfect is an important factor for domestic consumers to consider buying cars. However, in 2014, China’s recalled vehicles due to airbags and seat belts reached 1,193,100, accounting for 23.62% of the total number of recalls. This is indeed somewhat worrying.
Takata's airbag defect has tarnished the Japanese auto industry, and it has caused a big shock in the global automotive passive safety industry. Involved in Takata, in 2014, the total number of Japanese cars recalled by China's auto market due to airbag problems exceeded 800,000, involving brands such as Honda, Toyota, Nissan, Mazda, Infiniti, and Acura. FAW-Volkswagen recalled a total of 270,600 domestic Audi A4L and imported A4 allroads from May 2012 to October 2014. The reason for the recall was that some vehicles were safely installed due to airbag control unit software parameters. The air bag cannot be opened correctly.
The recall of seat belt problems is mostly related to the failure of the tensioner. In May and August last year, Shanghai GM recalled 32,000 domestic Angola and imported 26,600 Angray, all of which were locked by seat belt tensioners on the seat belts when the vehicle collided. It may lag behind and there are security risks. In December last year, BMW recalled 846 vehicles of the 3 Series, which were related to the environment in which the vehicle was used. When the temperature was below zero degrees Celsius, the seat belt on the right side of the front row may be difficult to pull out or even pull out, causing passengers to lose protection.
■ The “Retained Axis Door” suspension has only four recalls related to the record suspension system, with a total volume of 713,900 units, accounting for 14.13% of the total number of recalls. In such a quantity, "credit" belongs to FAW-Volkswagen New Sagitar.
It is reported that the new Sagitar rear suspension produced by FAW-Volkswagen after May 1, 2014 has all been changed back to independent suspension, and the coupled rod rear suspension previously used has created a single recall of the single brand in the domestic auto market in recent years. recording. With the intervention of the General Administration of Quality Supervision, Inspection and Quarantine, FAW-Volkswagen released a report in October last year, recalling 563,600 domestically produced new sagitars and 17,400 imported beetles equipped with coupled rod rear suspensions produced in the past three years. The arm may accidentally break after the vehicle is hit. However, FAW-Volkswagen's solution to the "patching" of the rear suspension has not been recognized by consumers.
Imported Cadillac also has a production assembly error. In September last year, Shanghai General Motors Co., Ltd. filed a recall plan with the AQSIQ and decided to recall a total of 107,700 imported Cadillac SRXs from July 2009 to August 2014. The reason for the recall was the rear suspension adjustment link assembly problem. The torque of the connecting rod nut may not meet the standard requirements, and looseness may occur after long-term use. SRX is a GM's luxury SUV, but the nut torque assembly on key components is not up to standard and lasted for 5 years, which can not help but question the GM production management and monitoring capabilities.
â– Electronic control module problems or increasingly prominent reasons for car recalls in 2013 and 2014 can be found that automotive electronics-related control software parameter settings and electronic control module safety are increasing. With the increasing use of automotive electronics and the promotion of active and passive safety functions of body electronics, there will be more recalls in the future due to defects in automotive electronics hardware and software.
Not only the above mentioned airbag control unit software parameter setting problem caused Audi 270,000 vehicles recalled, FAW Cars 15,798 Pentium B50, Dongfeng Passenger Car Company 2848 A60 sedan also recalled due to abnormal operation of the airbag control unit; 1909 The imported Land Rover Range Rover has not been upgraded to the latest version due to the body control module software, which caused the steering and dangerous double flash warning lights to fail and recalled; 3040 imported Subaru Foresters were improperly set by the engine control program and the high temperature caused by abnormal engine load High-pressure gas is damaged by spark plugs or pistons; Sichuan Automobile recalled 7,796 light buses due to low ABS actuator assembly protection capability or ablation of ABS circuit boards. In addition, the electrical component materials and design of the system of seat control and lighting control are also the main reasons for many recall events.
In addition, although there have been few incidents due to the recall of tire quality in recent years, the companies involved in each recall are very extensive. At the beginning of last year, 30 producers including Hualing Xingma, Laiyang Hongda Road Construction Machinery and Sany Auto recalled the trucks and buses equipped with Bridgestone and Fengchitong brands from January 2012 to September 2013. A total of 10,942 vehicles were used for tireless radial tires. The main reason is that the manufacturing process is not perfect, resulting in insufficient bonding strength of the joint parts of the rubber material. After the driving, the inner surface of the tire will be cracked, and the tire may be bulged or even leaked.
