Chinese manufacturer BYD has officially recalled 88,988 units of the Qin Plus DM-i plug-in hybrid model for a safety recall. The measure affects vehicles produced between January 2021 and September 2023 in the Asian market. The central defect involves the lithium battery pack, which poses a risk of critical failure while driving. The automaker identified the problem after internal quality analyzes and technical reports of power loss.
Administração Estatal of Regulação of Mercado (SAMR) of China supervises the operation. Documentos technicians point out that an anomaly in the battery tray can generate leaks and short circuits. The problem compromises the safety of occupants, with the possibility of sudden loss of power on highways and the risk of thermal fire. The government agency determined agility in communication with owners to avoid traffic accidents resulting from mechanical failure.
Detalhes power system failure technicians
The core of the problem lies in the assembly of the wiring harness inside the high voltage package. Continuous friction during car use wears down the cable insulation. Essa degradation exposes the conductive wires, facilitating undue contact with metal components of the car’s structure. Constant friction on uneven roads accelerates the process of breaking the original factory plastic protection.
The infiltration of coolant makes the situation worse. Quando the fluid reaches the area with compromised insulation, a reaction occurs that destabilizes the lithium cells. The vehicle’s electronic management system is often unable to isolate the fault in time to avoid abruptly cutting power to the electric motor. The sudden interruption of the power flow instantly disables the car’s traction.
Software Repair and Update Procedimentos
The automaker established an action plan divided into two main fronts to mitigate risks. Owners must schedule a visit to authorized dealers for physical inspection of components. Damaged parts will be replaced at no cost to customers. Técnicos specialists will carry out stress tests on the electrical system to confirm the feasibility of repairing each affected unit.
Além of mechanical intervention, the company will implement improvements to the car’s programming code. Remote updating aims to optimize the safety parameters and response time of the on-board computer.
- Instalação of a new continuous monitoring software for high voltage system.
- Configuração visual and audible alerts on the instrument panel in the event of a thermal anomaly.
- Substituição physical of battery trays showing premature insulation wear.
- Revisão complete of the affected wiring harness to ensure circuit integrity.
The update via OTA (Over-The-Air) allows part of the problem to be monitored even before visiting the workshop. The system will now identify abnormal temperature variations with greater precision. Veículos that present critical data in the remote diagnosis will receive priority in scheduling the physical service. The connectivity of recent models makes it easier to apply preventive fixes on a large scale.
Histórico recent calls from the automaker at Ásia
The current safety recall is not an isolated event in the company’s recent operations. In October of the previous year, the brand had to recall more than 115,000 units of the Tang DM-i and Yuan Pro models. The motivation also involved risks associated with the battery system and the possibility of overheating. The recurrence of electrical problems mobilized engineering teams to review parts supply standards.
A month earlier, in September, another massive campaign affected production lines. Cerca of 96,000 vehicles of models Dolphin and Yuan Plus entered the list of mandatory repairs. The defect on that occasion was concentrated in the energy converter, which had manufacturing flaws capable of interrupting the operation of the electric motor while it was moving. Service logistics overloaded the network of accredited workshops at the time.
The sequence of recalls raises debates about quality control in the electric vehicle industry’s supply chain. The rapid expansion of assembly lines requires more rigorous verification processes. Electronic components Fornecedores faces pressure to maintain delivery volume without compromising the reliability of structural parts. The balance between mass production and vehicle safety dictates the pace of industrial operations.
Impacto in the Chinese market and brand sales figures
Apesar technical challenges, BYD maintains a leading position alone in the global automotive market for electrified vehicles. The October commercial balance recorded the sale of 441,000 units, setting a new monthly record for the manufacturer. The volume represents significant growth compared to the same period of the previous year. The acceptance of the Asian public supports the corporation’s high profitability.
Plug-in hybrid models, the category in which the Qin Plus DM-i falls, continue to drive financial results. Sales in this segment surpassed the mark of 214,000 registrations in a single month, reflecting a 31% increase in demand. Consumidores seek the versatility of combustion combined with the economy of electric propulsion for long journeys. The still-developing charging infrastructure justifies the preference for dual engines.
The fully electric car segment also presented robust numbers in the corporate report. Foram delivered more than 223,000 units to buyers in the same thirty-day span. The portfolio diversification strategy allows the company to absorb the negative impacts of recalls without losing market share to direct competitors. The production scale guarantees comfortable profit margins for investments in research.
Automotive safety and regulation Protocolos
SAMR’s actions highlight the tightening of road safety rules in China in 2026. The regulatory body has intensified supervision over new energy vehicle manufacturers. The demand for transparency in reporting structural failures has become a priority for the Asian government. Multas Severe consequences await companies that omit data on fire risks or braking failures.
Especialistas in automotive engineering point out that the complexity of hybrid systems requires rigorous preventive maintenance. The integration of combustion engines with high-voltage electrical architectures creates an environment conducive to thermal wear. The development of solid-state batteries appears as a technological alternative to mitigate the risks inherent to liquid lithium. Laboratórios testing works on certification of new insulating materials.
The global market is closely watching developments in the quality policies of Chinese manufacturers. The expansion of these brands to Europa and América Latina depends on consumer confidence in the durability of the products. Rapid response to manufacturing defects, through structured recalls, serves as an essential mechanism for preserving corporate reputation in the long term. Transparency in the repair process defines customer loyalty to the brand ecosystem.
