740,000 vehicles have been recalled globally.
Recently, a number of Volvo owners reported to Time Finance that the XC60 and S90 models they purchased had low-frequency resonance problems. Specifically, when the vehicle is idling or driving at a low speed, low-frequency resonance continues to occur in the vehicle, causing discomfort for drivers and passengers, and even dizziness, dizziness, nausea, etc. in severe cases.
Previously, according to foreign media reports, Volvo Cars will recall 736,400 vehicles worldwide due to a malfunction of the AEB (Automatic Emergency Braking System). According to Volvo's recall requirements, the recalled batches are almost all of the XC40, S60, V60, XC60, S90, V90, XC90 and other models on sale between January 2019 and March 2020. Currently, the recall process in the Chinese market is in progress.
Volvo has always focused on safety, and its founder even put forward that "the guiding reason for doing anything must be safety." It is understood that the global sales of Volvo Cars in 2019 were approximately 705,500, an increase of 9.8% year-on-year. This is the first time that Volvo Cars' annual global sales exceeded the 700,000 mark since its establishment in 1993. The sales volume in the Chinese market was approximately 161,400, an increase of 18.2% year-on-year. Among them, the annual sales volume in the mainland market was approximately 154,600 vehicles.
From the perspective of specific models, the XC60, XC90 and S90 are Volvo’s main sales models. The sales of the three models in the Chinese mainland market in 2019 were approximately 62,600, 17,800 and 43,100, respectively, representing a year-on-year increase of both More than 20%.
Regarding the problem of low frequency resonance, Time Finance contacted Che Yanhua, Vice President of Marketing of Volvo Cars Greater China Sales Company, and the other party hung up on the grounds that they were in a meeting.
Lawyer Duan Zhaoqi of Shanghai Jintiancheng Law Firm told Time Finance that low-frequency resonance is a car failure, which directly affects the use of the vehicle and the safety of the owner. The certificate of conformity is only a self-inspection of the manufacturer's own products. It cannot fully guarantee the quality of the product and proves doubtful. According to relevant regulations, within the validity period of the three guarantees, if the car repair time exceeds 35 days, or the repair caused by the same product quality problem exceeds 5 times, consumers can change the car. It is recommended that car owners keep the evidence and actively negotiate with sellers and manufacturers.
Strange "headache"
The owner Li Sheng (pseudonym) told Time Finance that he had proposed a Volvo S90 in October 2019 . He first bought this car because of Volvo's concept of safety and environmental protection. Although I heard about low-frequency resonance at the beginning, sales at the time indicated that this was no longer the case for the new car, and the dealer did not provide a test drive model. Because he was in a hurry to use the car, he placed the order directly.
But then he found out that he was "in a trick", "The driving experience on the day of picking up the car was very bad. His head was buzzing, and there was a feeling of swollen ears pressing on the eardrum. After returning home, I found other relatives and friends to test the car, everyone The feelings are similar. Later, in the course of daily driving, he often feels ear pressure, even intermittent tinnitus, sleeplessness or insomnia."
Hubei Che Yanqiang (pseudonym) also had similar experiences, he told Time Finance, for the convenience of family travel, purchased an XC60 in May 2018. At first, it was only driven when running at high speed, but the noise was relatively loud during driving. As the frequency of use increases, my hair is always boring, and my family feels uncomfortable sitting in the passenger seat, but it doesn't take it too seriously.
This situation lasted for more than a year. He was unable to work due to the worsening of the headache, so he went to the hospital to have a brain CT. The doctor told me that it was an vascular headache, so I took time off for half a month. Later, I found in the forum that many riders have similar feelings. He realized that this may be related to the low-frequency resonance of the vehicle.
At present, more and more car owners have encountered similar problems. According to Li Sheng, he has joined two rights protection groups, all of which are Volvo owners who have encountered low-frequency resonance, about 500 people.
However, what made them even more "injured" was that manufacturers and 4S shops "kick the ball" with each other. Multiple car owners said, They called the manufacturer’s 400 and 4S shops many times, but they did not give a clear answer and solution, and ignored the car owner.
Li Sheng said that because of the low frequency resonance problem, he went to the 4S shop for inspection many times. He was subsequently told that the low-frequency noise in the car was as high as 80 decibels, but below 90 decibels, which was within the normal range. Headache and tinnitus are just the subjective feelings of the car owner and have nothing to do with the car. The 4s shop insists that everything is qualified and they have a factory certificate.
According to Times Weekly, some Volvo 4S stores have responded that some customers did come to report this problem, but there was no problem after their inspection. Vibration and noise during the use of the vehicle are normal physical phenomena. In line with national standards. In response to the problems reported by car owners, the current proposal is mainly to upgrade the software and adjust the sealing strips. "For individual car owners, try to seal their cars, but not modify other parts of the car."
At present, some Volvo car owners have been "forced" to become engineers, studying sound insulation and noise reduction all day long. Some car owners have installed anti-vibration materials on the chassis, installed iron blocks on the exhaust pipes, or reinstalled soundproof cotton, Anti-vibration plate, but the effect is limited. Some people are even forced to sell cars because they can’t stand the low-frequency resonance. This has also caused the car owners to bear part of the economic loss. "The new car can lose 100,000 to 200,000, and the car dealer is not willing to accept it. Now this car is coming to me. It’s already a torture.”
Problems frequently occur
It is understood that due to physical characteristics, resonance on the car always exists, and the engine is idling. Yes, there are also cars running on the road, as long as the resonance frequency of the relevant parts of the car is maintained within the normal value, it is normal, and there will be no impact.
In contrast, Volvo's situation may be more serious. It is understood that the Volvo XC60 body resonance problem as early as the end of 2018, some XC60 owners published a post about the hot car idling resonance roaring problem, which quickly caused a large number of car owners and prospective car owners to watch, pushing the Volvo body resonance problem to the public's view.
As for the specific reasons, there is no definite explanation. Some car owners attribute the low-frequency resonance to the design, and the anti-vibration plate and the silencer cotton are not in place. Indeed, this is a design flaw. The "lightweight" design of Volvo's SPA platform and the unreasonable design of sound-absorbing cotton such as shock absorbers may be the cause of this defect; some insiders also said that this may be an exhaust system design problem, or an engine and exhaust There is a problem with port matching.
Previously, Volvo was named by CCTV due to quality problems. In September 2018, the CCTV 315 column team published an article "315 in action: Volvo that is out of control", in which it was mentioned that many owners of imported Volvo XC60 are facing the defects of the vehicle's dual-clutch transmission in daily driving. Life-threatening moments. Subsequently, Volvo officials gave relevant explanations and gave two solutions: "repair" and "replacement".
According to the vehicle reliability survey report of JDPower, a well-known third-party research organization in the United States, Volvo Cars had 162 failures per 100 vehicles in 2018, which was much higher than the industry average; Volvo Cars per 100 vehicles in 2019 There were 204 failures in the car, which was the third lowest in the entire ranking and became "one of the most unreliable car brands." Since
was acquired by Geely Holdings, Volvo Cars has been on the "fast lane", and its global sales have increased for 6 consecutive years. In 2019, Volvo Cars has sold more than 700,000 vehicles worldwide for the first time since its establishment 90 years ago. This is mainly due to the continued strength of the Asia-Pacific market centered on China. In order to further increase sales in China, Volvo Cars is accelerating the localization process. However, large-scale recalls and frequent problems have also planted "hidden dangers." (Beijing Time Finance Ouyang Xizi)
