The jeep's herdsman is still self - burning after the recall
the state qqsiq ordered the Chrysler Jeep to suspend imports. According to CCTV weekly quality report yesterday, as of March 25, 2011, there were 18 incidents of Autobots in China. Among them, there were 9 suspected fires caused by excessive oil temperature.
flat road normal driving spontaneous combustion of spontaneous combustion
Jiangsu car owner Cen said that in January this year, he just bought more than one year of imported herdsmen unprovoked car spontaneous combustion accident. In retrospect, Mr. Cen still feels "very afraid". Mr. CEN is not able to understand that the location of the vehicle's spontaneous combustion is not a "high difficulty" section, but a flat hard rock road, which does not make any difficulty for the rodsman's cross-country ability. In just a few minutes, the imported Wrangler and vehicle belonged to Mr. Cen worth hundreds of thousands of dollars, all of which were burned and his property was seriously damaged.
Mr. Chen's accident is not a case. As early as 2009, a car owner in Beijing had a similar situation. According to the owner's investigation, there were at least six or seven cases of spontaneous combustion of the herdsman in China.
15 spontaneous combustion accidents,
the state QQ defect product management center in July 2009, conducted a survey on the start-up defects of the Chrysler Jeep horse man. According to the survey, there were more than 10 cases of spontaneous combustion of Jeep Wrangler from July 2009 to September. In November 2009, AQSIQ issued the first warning notice about the safety risks of some imported Chrysler Wrangler SUVs.
in January 2010, Chrysler (China) Auto Sales Co., Ltd. recalled 1809 of the jeep horse ranch people in 2007 and 2008 in China because of the possible risk of self ignition of vehicles.
however, the recall did not change the problem of spontaneous combustion of herdsman. According to data from Chrysler (China) auto sales Ltd., 18 herdsman auto spontaneous combustion occurred in China by March 25, 2011. Among them, there were 9 suspected fires caused by excessive oil temperature. Of these 18 spontaneous combustion incidents, 15 have not reported to the General Administration of quality supervision, inspection and quarantine, nor have they filed for the information management system of defective product management centers.
according to the statistics of the State General Administration of quality inspection (qqsiq), the imported herdsman car began to sell in our country in the second half of 2007, and 7341 units have been sold at the present time. The known spontaneous combustion incidents have reached 18, experts pointed out that the incidence of such spontaneous combustion is very abnormal. 15 of them occurred after the recall in January 2010, which means that the recall did not fundamentally solve the problem of the spontaneous combustion of the herdsman.
the exorbitant oil temperature of the gearbox is now a mystery to
Chrysler, and the jeep horse man does not have a problem in design, only due to "overuse" under extremely harsh conditions. Such as running in the sand for a long time, or overloading vehicles in the snow.
according to Wang Kaiming, an expert on the defect product management center of the State Administration of quality inspection (qqsiq), according to technical analysis, it was found that the reason for the spontaneous combustion of the jeep herdsman is that the oil temperature of the automatic transmission is too high, causing the mixture of oil and gas to be ejected from the vent of the gearbox, and contact with the high temperature components such as the surrounding three element catalyst, causing a fire.
according to the reporter, in January 2010, the recall measures adopted by Chrysler mainly solved the problem of overheating of oil temperature in the gearbox of the jeep's herdsman. What Chrysler takes is to install a gearbox oil temperature alarm system, that is, when the oil temperature of the jeep's Gearbox reaches 135 degrees centigrade, the alarm will be alarm and the alarm will continue for 30 seconds.
but according to the comparison and analysis of the improved 2011 and 2010 Jeep horse ranch people after the improvement of the defective product management center of the State Quality Inspection Administration, it was found that after several tests, after the oil temperature of the gearbox reached 135 degrees centigrade, the alarm sound lasted only two seconds. At the same time, the leakage of transmission oil was also found in the experiment. Experts pointed out that if the experiment continues, it is likely to cause vehicle spontaneous combustion.
in addition, according to the data provided by Chrysler, 2008 to 2010 jeep herdss run for 15 minutes at a speed of 32 kilometers per hour under the condition of sand, and the oil temperature of the gearbox will reach 135 degrees Celsius. Therefore, experts warn that Jeep Wrangler is not suitable for long operation in harsh conditions such as sand.
