AVTOVAZ began equipping certain Largus models with an anti-lock braking system supplied by the Chinese manufacturer Trinova. Reports circulating on the unofficial AvtoVAZ public page on VKontakte, Avtograd, suggested that the system did not perform as expected during testing. This raised concerns about the braking performance under critical conditions and prompted a closer look by the engineering team. The move to introduce a new ABS unit was part of a broader effort to modernize the vehicle lineup, but the initial results indicated potential issues that could affect a portion of the upcoming dealer inventory. In this context, the company faced a decision point: proceed with confidence in the new component or pause to ensure reliability across all trim levels and configurations, particularly as the cars were slated for sale to end customers. The situation highlighted the importance of thorough validation when integrating electronic braking control systems into production vehicles, especially in markets with rigorous safety expectations.
The core problem appeared to involve the ABS becoming active or misbehaving under aggressive braking, though exact symptoms were not publicly detailed. The ambiguity around the fault behavior meant that the internal documentation and test notes remained restricted to the project engineering teams and management. Dealers and customers rely on the ABS to modulate wheel slip, maintain steering control, and reduce stopping distances on varying road surfaces. Any deviation from expected ABS performance could have serious implications for vehicle safety and consumer trust. As a result, the decision was made to halt the dispatch of several hundred Largus units produced in multiple trim levels, which were already prepared for shipment to dealerships. The pause was intended to prevent the distribution of potentially nonconforming vehicles and to allow time for a comprehensive root-cause analysis. The situation has also underscored how supply-chain contingencies and cross-border supplier integrations can interact with local validation processes, especially when new components enter mass production for a major brand.
At present, Avtovaz engineers and quality assurance specialists are actively diagnosing the root cause of the ABS irregularities and are preparing a retest plan aimed at validating corrective actions. Their approach includes verifying electrical connections, software calibration, sensor performance, and interaction with other vehicle stability systems under a range of braking scenarios. The company is coordinating with its test fleet and conducting additional road and laboratory assessments to ensure that the ABS operates consistently across all anticipated operating conditions. Once the retesting demonstrates stable and compliant behavior, the Largus lineup will be re-entered into the distribution pipeline and sent to dealers. This rigorous process emphasizes the commitment to safety and reliability that customers expect, even when introducing newer electronic features into a longtime model family.
