AutoBeta(AutoBeta.net)08/30 Report--
I learned from the car quality network that recently, the website has received a lot of complaints about BMW engines, mainly focused on brilliance BMW 3 Series. BMW 3 series engine problems mainly focus on cooling system failures and engine leakage antifreeze two major aspects, some car owners reported that soon after buying a new car, serious liquid leakage, and has not been solved.
A car owner complained that he bought a 2020 320Li M sports suit at a 4S store on August 21 and found a serious leak of antifreeze on the morning of August 27th. The car has not had any bumps or bumps so far, and it is now seriously suspected that the car has quality problems when it leaves the factory.
There are also car owners reported that the 2020 325Li M sports suit version, which was purchased in March, was successfully picked up on April 13th, and on August 29th the vehicle was prompted to add coolant, and then the car was towed to the 4S store. After inspection, it was found that the problem was caused by a problem with the thermal management module and needed to be replaced. The car owner said that more than 90 car owners have encountered the same problem, all due to the abnormal loss of vehicle coolant caused by the thermal management module, all of which are vehicles in batches from March to April 2020, and the manufacturer neither recalls nor issues relevant announcements to explain the situation.
According to vehicle failure statistics, the liquid leakage problem of BMW 3-series engine is mainly concentrated in 2017 and 2020 models. According to the search, the problem of BMW leakage can be traced back to 2017, while only for the leakage of the new BMW 3-Series, there are many posts on the forum.
Judging from the problem that many car owners reported on the forum that the new car was leaking antifreeze, most of them occurred after a few months or thousands of kilometers of driving a new car. As can be seen from the content of the post, the owners of the leaking car should have encountered a failure of the thermal management module.
It is worth mentioning that in addition to engine leakage antifreeze, brilliance BMW New 3 Series has also been recalled because of engine oil leakage. On November 8, 2019, brilliance BMW filed a recall plan with the State Administration of Market Supervision and Administration, recalling a total of 49 domestic brilliance BMW 325i and 325Li vehicles produced from May 21, 2019 to September 24, 2019.
The reason for the recall is that the needle roller bearing outer ring of the vehicle engine balance shaft may not be pressed correctly into the engine crankcase, and the bearing outer ring may be detached from the crankcase during engine operation. This may cause the balance shaft to become loose and come into contact with the crankshaft, interfere, and cause damage to the engine crankshaft and / or cylinder block, which may cause engine oil leakage if the engine is seriously damaged. In the worst case, the engine flameout in the process of vehicle driving can not be ruled out, which will reduce the maneuverability of the vehicle and there are hidden dangers.
It is understood that the new 3-series of brilliance BMW was officially put on sale in June 2019, launching two models: standard axis version (code G20) and long axis version (code G28). The 320bot 330 model went on sale at the Guangzhou Auto Show in November, with prices ranging from 29.39 yuan to 318900 yuan and from 37.99 yuan to 409900 yuan.
Data show that from January to July 2020, brilliance BMW's cumulative sales increased by 33.99% to 323699 vehicles, of which brilliance BMW 3-Series sales increased by 22.69% to 79740 vehicles, accounting for 24.63% of brilliance's market share.
In terms of sales data, the sales of the BMW 3-Series are second only to the 5-Series, which should not be the case for a hot and well-sold model. At present, a number of car owners have set up a group chat on the leakage problem, and if the problem is not resolved as soon as possible, there will be no new round of rights protection incidents.
