·The engine has become a complaint in the hardest-hit area, and the independent joint ventures each account for half of the country.

As the car ownership continues to rise, the problems exposed are also increasing. According to statistics from specialized research institutions such as the Auto Complaints Network, the Auto Complaints Network received a total of 3,281 complaints involving engines in 2014, an increase of 2.53% from 3,200 in 2013. In the 2014 complaints about the engine, the joint venture brand had the largest number of complaints, with a total of 1853 cases, accounting for 56.95%; the self-owned brand “followed”, a total of 1244 complaints, accounting for 38.23%; the number of imported brand complaints was 157 Zong.
Judging from the volume of complaints, self-owned brands and joint-venture brands each occupy “half of the country”. Although the number of joint venture brand complaints is larger, it is also related to its sales volume and market holdings. For independent brands, domestic enterprises have existing ones. The core of engine technology is still in the hands of foreign companies, and it is precisely because some domestic brands are immature about engine technology. Therefore, after the engine has problems, it is often helpless, which has led to further intensification of domestic brands related to engine complaints.
From the direction of complaints, among the 3,281 complaints about engine complaints in the Automotive Complaints Network in 2014, there were 1,543 complaints about abnormal engine noise, accounting for 38.3%; 818 complaints about unstable engine idling, accounting for 20.42%; There were 489 cases of oil consumption increase, accounting for 12.21%; 569 cases complained of difficulty in starting the engine, accounting for 14.21%; 595 cases complained of engine leakage, accounting for 14.86%. (Some complaints select multiple complaints)
Among all 3,281 complaints about engines, 2,546 cases have been processed, accounting for 77.6%. However, from the perspective of vehicle satisfaction, only 3.5% of the owners expressed satisfaction with the results. There are still 735 complaints related companies. Not processed.
From the perspective of engine vehicle status: the proportion of complaints about quality problems during the running-in period (including one month) reached 17.06%, the complaints during the warranty period accounted for 60.02%, and the complaints outside the warranty period accounted for 22.92%. From this point of view, most engine failures occur during the warranty period, so the quality of the engine can not be ignored.
Maintenance has always been the main complaint of the owner. In the analysis of engine complaints, the proportion of repairs required is 24.37%, and the proportion of recalls is 22.48%. From this point of view, after the engine has a problem, the owners are not very eager to solve the problem through maintenance, the recall has become the first choice for complaints.
Regarding the abnormal noise of the engine, Mr. Yi of Tianjin issued a complaint in the Auto Complaints Network that the abnormal noise of the JAC and Yue RS engine purchased from 2013 has appeared, and the manufacturer also has a maintenance record. So far, the engine has passed the insurance before telling the owner. If you can't fix it, Mr. Yi said that the 4S shop can't be repaired. Where can I go for repair? Who will bear the loss?
As the core component of the car, the engine's abnormal sound marks that the technical state of a certain engine has changed. Mainly due to some parts worn or even assembled or improperly adjusted. The abnormal noise of the engine caused problems in the car engine, which would threaten the safety of the car and the safety of the people on the car.
According to the Auto Complaints Network, there were 1,543 complaints about abnormal engine noise throughout the year, accounting for 38.3% of all engine complaints. A total of 1226 complaints were resolved in about 80% of the total, and the remaining 317 complaints were not responded by the relevant manufacturers.
Complaint about engine idling instability Mr. Chen of Xuzhou, Jiangsu Province, complained on the Auto Complaints Network that the 13-year-old Zhengzhou Nissan Sunshine has started to drive 2000 rpm since the start of the car, and it will take 1000 minutes after 4-5 minutes. turn.
Unstable engine idle speed is one of the common faults in car use. There are many reasons for this. In addition to the oil road problems caused by the use of inferior gasoline, it is generally caused by problems in the engine parts or the intake system. Although the idling instability will not affect the safety of the owner, it is devastating to the daily driving of the owner.
According to the data of the Auto Complaints Network, in the whole year of 2014, there were 818 complaints about unstable engine idling, accounting for 20.42% of all engine complaints. Nearly 90% of them were finally resolved.
Complaint about engine leakage Mr. Peng of Hubei issued a complaint in the Auto Complaints Network that the Tianjin FAW Weizhi V2 engine that he purchased was only 3,000 kilometers away from oil leakage, and the repairs did not help. Most engine leakage phenomena are general faults and minor faults, and a few are serious faults and fatal faults. If some leakage faults are not eliminated in time, it is likely to become more serious and directly affect the performance of the whole vehicle, so it needs to be resolved as soon as possible.
According to the data of the Auto Complaints Network, in the whole year of 2014, there were 595 complaints about engine leakage, accounting for 14.86% of the complaints. Among them, 440 cases of nearly 80% of complaints were resolved, and 155 complaints were caused by the failure of relevant manufacturers.
Although the car three-package stipulates that "household car products are within 60 days from the date of the seller's invoice to purchase the car or within 3,000 km of the driving range (whichever comes first), the main parts of the engine and transmission have product quality problems, consumers You can choose to replace the engine and transmission for free." However, as the core component of the car, replacing the engine not only has a greater negative impact on the value of the car, but also affects the service life of the car.
Therefore, once the car has a problem with the engine quality during the warranty period, most of the owners will choose to return the car, but the standard for the engine return car in the three-package of the car mentions that "the engine, the transmission have been replaced 2 times, or the same main engine or transmission. Parts due to their quality problems, after two replacements, can not be used normally, the engine, transmission and its major parts replacement times are not repeated. The same part must be replaced 2 times before the replacement can be carried out, but for the 4S shop, this "same part" can operate a relatively large space, so in the face of the engine complaints, the car mainly wants to defend the rights, it is still difficult . This is also the reason why only 3% of the 70% of the complaints handled have been satisfied.
