Daihatsu Motor Co. is recalling 298,748 light trucks in Japan due to a battery-area bolt defect that may prevent engines from starting [1].
The recall affects a significant volume of commercial and utility vehicles, posing a risk of sudden operational failure for owners who rely on these trucks for daily business.
According to a filing with the Ministry of Land, Infrastructure, Transport and Tourism, the issue stems from a bolt located near the battery [3]. When water accumulates in that area, the bolt can corrode, which may eventually lead to a failure in the engine's starting mechanism [3].
The recall includes vehicles manufactured between December 2021 and July 2025 [4]. Daihatsu and its OEM partners, Toyota and Subaru, are coordinating the effort to address the defect across the affected fleet [1].
Company data indicates that 27 cases of this specific issue have been confirmed [1]. The manufacturer said it is notifying owners of the affected units to ensure the bolts are inspected and replaced where necessary to prevent vehicle immobilization.
This action follows a pattern of quality control scrutiny for the manufacturer. The company said it is working to resolve the hardware vulnerability across the 298,748 units to avoid further reported failures [1].
“Daihatsu is recalling 298,748 light trucks in Japan due to a battery-area bolt defect.”
This recall highlights a vulnerability in the weather-proofing of critical electrical connections in Daihatsu's light truck line. Because these vehicles are often used in rugged or outdoor environments where water exposure is common, a corrosion-prone bolt represents a significant reliability risk. The involvement of Toyota and Subaru as OEM partners expands the scope of the recall across multiple brands, emphasizing the integrated nature of the Japanese light-vehicle supply chain.
