Chinese regulatory authorities have confirmed the start of an extensive repair program involving vehicles from one of the country’s largest car manufacturers. The corrective action specifically covers 96,714 units of the Qin Plus DM-i model, manufactured between January 2021 and September 2023, aiming to neutralize a technical failure that could compromise the safety of the occupants and the integrity of the car.
Detailed investigations into the power management system identified a vulnerability in the battery controller capacitors. With continuous use and natural aging of the components, there is the possibility of microcracks that result in the module overheating. Essa thermal instability, if left untreated, considerably increases the risk of combustion in the energy compartment, requiring immediate intervention to prevent serious accidents.
Software update fixes power system failure
The strategy adopted to resolve the problem combines remote technology and physical replacement of components when necessary. Todos owners of affected vehicles will receive a software update via OTA (Over-the-Air), eliminating the need for immediate visits to the workshop for the first stage of diagnosis.
The new code implemented in the control module will now actively monitor the behavior of the capacitors during conduction.
If the system detects any anomaly or voltage variation that indicates a risk of failure, an alert message will be displayed on the vehicle’s instrument panel. Nessa situation, the driver is instructed to look for an authorized dealer, where the complete replacement of the battery controller will be carried out free of charge, guaranteeing the definitive elimination of the risk of fire.
Safety procedures reinforce commitment to consumers
This recall highlights the importance of continuous quality monitoring in electrified vehicles, especially high-voltage components.
Road safety experts reinforce that owners of hybrid and electric models must always pay attention to system warnings and keep software updates up to date. Preventive maintenance of battery systems is crucial to ensuring the longevity of the automobile and the protection of all road users, demonstrating the industry’s responsibility to correct production failures in a transparent manner.
