Since February 15th, BMW has announced a continuous global recall, involving about 750 thousand different types of cars, of which about 500 thousand in the United States, Canada, Japan and South Africa, which have been the largest recall for nearly 1 years. According to the latest information, the recall also includes a total of 2116 BMW X5 cars imported in mainland China in 2007~2010 years. The daily economic news reporter noted that the main reason for the recall in mainland China is due to brakes. In February 15th, BMW announced the recall of more than 30 thousand X5 series of X5 series of off-road vehicles in the United States as brake fluid leaks could cause power auxiliary brake failure. BMW said the recall of X5 models in the United States covered 2007~2010 models, from September 12, 2006 to March 18, 2010, using the 8 cylinder engine. The vehicles involved in the recall in mainland China belong to the BMWX5 series. The reporter consulted the State Quality Inspection Bureau website, and the data showed that BMW (China) Auto Trade Co., Ltd. submitted a recall report to the State Quality Inspection Administration (cqsiq), and will recall some of the BMW X5 (8 cylinder engine) from 2007 to 2010 since March 18, 2013. The production date is from May 9, 2006 to 201. In March 18th 0, according to the company's statistics, 2116 vehicles were involved in the mainland of China. The brake booster of the vehicle may be polluted by the lubricating oil in the vacuum pump, so the brake assist function may be affected. In some cases, the vehicle may lose the brake assist function, which may cause the vehicle braking performance to decline, and there are potential safety hazards. In February 16th, the National Highway Traffic Safety Administration (NHTSA) published the relevant information on the engine failure of BMW engine on the website. The reason is that there is a problem with wiring harness of battery cars, which may cause engine to stall. When the vehicles are used for a certain number of years, the wiring of the fuse box and the lines of the battery are aging, which may cause a short circuit between the battery and the fuse. As a result, the automobile power can not be supplied normally, resulting in engine failure. On the same day, BMW announced the recall of 504 thousand vehicles in the US market and the recall of 65 thousand cars in the Canadian market. It is understood that the recall vehicles include 2007 to 2011 BMW 3 Series cars, sedan cars, open cars and wagons, 2008 to 2012 BMW 1 coupe and open cars, and the BMW Z4 sports cars listed from 2009 to 2011. Some major auto makers, such as BMW and Japan's Toyota Corporation, have been recalling the recalls in recent years, because the companies use the same parts in different models to save costs. At the end of October last year, BMW Motor North America announced the recall of 45 thousand and 500 7 Series cars in the United States, correcting the parking defects. In February 19th, data showed that BMW motor was recalling 100 thousand vehicles in Japan and 50 thousand in South Africa. The vehicle models involved include 1 series, 3 series, X1 series and Z4 series. These models are produced between 2007 and 2011. A spokesman for BMW said there were no reports of accidents due to these technical problems, and those models did not involve Europe.
