China Auto August 22 Recently, China Auto Quality Complaint Platform (https://315.auto.china.com.cn/) received a large number of complaints from owners of Chery Tiggo 8 PRO, saying that there was a high-frequency brake buzz in the vehicle, which was a common problem. To this end, hundreds of car owners spontaneously organized rights protection, hoping to promote Chery manufacturers to solve complaints. As a mid-level SUV model that just went on the market in May this year, the Tiggo 8 PRO was troubled by the buzz of the brakes when the new car was just bought back.
A car owner described to reporters that there was a brake buzz the next day after picking up the car, which could not be covered with music when driving. The most irritating thing was that there was still a high-frequency buzz after the flameout, and the buzz was in my ears after driving for a long time. I have been to the local service shop for inspection, but I have no results after many complaints. Later, I found that most cars have high-frequency beeps.
Another car owner, Mr. Gao, also told the column "Pony Says Car" in auto channel, China Net that more than 200 riders have beeps. When driving, the sound is very noisy, which is a high-frequency sound, and there are also beeps in the test drive. The 4S shop said that if you buy a domestic car, you should be psychologically prepared to accept these small problems, and you can only wait for the manufacturer to give a solution. After the interview, the reporter also learned that the owners all pointed the root of the buzzing sound problem to Chery’s "Onebox Brake by Wire". In fact, since Chery used the brake-by-wire in the Tiggo 8 series, owners of the Tiggo series have been complaining that the brake-by-wire has jitter and abnormal sound, until this time it broke out in the Tiggo 8 PRO. It is reported that the Onebox brake-by-wire system of the Tiggo series is independently developed by Chery, which is composed of vacuum booster pump, master cylinder, electronic vacuum pump, EPB and ESC. Although the manufacturer claims that the brake-by-wire system has higher braking efficiency, it seems that this system is not perfect and mature enough at present.
The reporter then gave feedback to Chery about relevant complaints. The official said that he would contact the owner as soon as possible to invite him to enter the station for treatment, carry out detailed inspection on the vehicle and provide specific solutions, and then he would do a good job in tracking the vehicle to provide customers with satisfactory after-sales and guarantee services. In addition, Chery will also arrange engineers and technicians to carry out detailed inspection and investigation on the causes of the above problems, and comprehensively verify and qualitatively analyze them from the aspects of quality and design, so as to determine whether the above problems are sporadic cases or multiple occurrences.
At the same time, the column "Pony Talking about Cars" is also further following up the latest development of the incident. Chery has also provided a solution of "installing sound insulation cotton" for some car owners, but the car owners think that this move is "stealing the bell" and has no real effect and does not solve the substantive problem.
In fact, it is not only the brake buzz of the Tiggo 8 PRO, but also some car owners report that the vehicle has encountered a safety hazard of brake hardening. A Tiggo 8 PRO owner said that on the one hand, when the car brakes, there will be a buzz, and the sound will be harsh. Secondly, when the car brakes suddenly harden twice during driving, it is necessary to step on the brakes twice and intervene in the backup brake. The backup brake has a slow response and poor braking ability. Coincidentally, another car owner told reporters that the vehicle suddenly braked hard and could not step on it during normal driving, and reported various fault codes.
According to the relevant provisions of the Provisions on Responsibility for Repair, Replacement and Return of Household Automobile Products, if the household automobile products have steering system failure, brake system failure, body crack or fuel leakage within 60 days from the date when the seller issues the purchase invoice or within 3000 kilometers (whichever comes first), and consumers choose to replace or return the household automobile products, the seller shall be responsible for free replacement or return. Therefore, some car owners require manufacturers to return cars, and car owners are actively communicating with Chery through various channels to solve related problems.
