What is the reason for the recall and replacement of the transmission in the BYD Song Max?
4 Answers
BYD Song Max is being recalled for transmission replacement due to issues with the gearbox. The advantages of the Song Max's transmission and dual-clutch transmission are as follows: Transmission of the Song Max: This vehicle is equipped with two types of transmissions: a 6-speed manual transmission and a 6-speed dual-clutch transmission. The BYD Song Max series all use a 1.5-liter turbocharged engine, and the dual-clutch transmission is the most suitable to pair with a turbocharged engine. Advantages of the dual-clutch transmission: The dual-clutch transmission has high transmission efficiency and fast gear shifting. The dual-clutch transmission is developed based on the manual transmission, and its structure is similar to that of a manual transmission. The only difference is that the dual-clutch transmission has an additional set of clutches and a gear-shifting control mechanism. The dual-clutch transmission is connected to the engine via clutch plates, which is why it has high transmission efficiency.
I think the main reason for the BYD Song MAX recall to replace the transmission is due to mechanical or software issues inside the transmission. Specifically, some batches of vehicles may have used less durable components in the transmission, such as bearings or gears that are prone to wear and breakage over long-term use, leading to rough shifting or even complete jamming. Another common issue is software bugs in the control unit, which may cause the transmission to misinterpret signals during high-speed driving, resulting in sudden downshifts or loss of power—a dangerous situation. This was discovered through BYD's own testing, and continuing to drive under such conditions could increase the risk of rear-end collisions or accidents, prompting the proactive recall for replacement or upgrades. As owners, we should visit the 4S store as soon as possible after receiving the recall notice—the entire process is free and takes about half a day to complete. For daily maintenance, avoid sudden acceleration or heavy loads, and regularly check the transmission fluid level to prevent potential issues in advance. This action reflects the company's responsible attitude toward user safety. While it’s not a major problem overall, it should still be taken seriously.
The recall of the BYD Song MAX for transmission replacement is primarily aimed at eliminating potential safety hazards. As a critical component, if the transmission malfunctions—such as leaking oil or getting stuck—it could cause sudden deceleration or engine stalling at high speeds, which is highly dangerous and could easily lead to accidents. BYD identified the defect through user feedback and quality inspections and promptly initiated the recall to replace the faulty parts, ensuring vehicles are safe for the road. As regular car owners, once we receive SMS or email notifications about the recall, it's best not to delay and schedule an appointment with the 4S store immediately for the transmission replacement. The process is usually free and takes only a few hours. During daily driving, if you notice similar issues like excessive shaking during gear shifts or unusual noises, these are often early warning signs. Maintaining smooth and gentle driving habits, along with regular maintenance checks, can help reduce the likelihood of future malfunctions. Recalls not only fix defects but also strengthen brand trust. Although the impact is widespread, timely handling ensures safety comes first—never take it lightly.
The reason for the recall of the BYD Song MAX to replace the transmission is that components inside the transmission may malfunction, such as damage to the shifting module or sensor failure, leading to unresponsive gear shifts or pauses while driving. As an owner who encountered similar issues, I received a notification, and after the free replacement under the recall, the car runs much smoother. It's important to pay attention to the transmission's performance daily; any abnormal noises or delayed responses should be checked early. The recall process is straightforward, and timely action by the owner is key.
