This matter came to light in February 2024 when Subaru initiated an investigation after receiving returned parts from reports indicating airbags failing to deploy as intended. Subaru collaborated with the supplier and submitted an equipment recall (24E-016) to the National Highway Traffic Safety Administration (NHTSA), signalling the commencement of evaluations regarding the safety implications for Subaru vehicles and the potentially impacted population. Subaru made the decision in March to launch a comprehensive safety recall campaign.
Digging into the technicalities of the issue, the defect report highlights a convergence of factors contributing to the capacitor cracking. It suggests that the utilization of alternate component sub-suppliers during short-term natural disaster recovery, combined with certain supplier processing methods, may have led to this vulnerability. Specifically, it’s noted that during a specific production period at a particular supplier, the ODS Sensor Printed Circuit Board (PCB) might have undergone deformation, thereby initiating cracks in the capacitor. Over time, these cracks could permit moisture ingress into the capacitor, ultimately resulting in a short circuit.
The ramifications of this malfunction are significant. When a short circuit occurs, indicators such as the SRS airbag system warning lamp and the front passenger’s frontal airbag OFF indicator illuminate. This signifies a potential failure of the front passenger airbag to deploy in specific crash scenarios, thus elevating the risk of injury to the occupant in the respective seat.
In response to this concern, Subaru has outlined a comprehensive course of action. Owners of the affected vehicles will be contacted and requested to visit authorized dealerships for the replacement of ODS sensors on the front passenger seat. Initial communication regarding the safety risk is anticipated to be dispatched by May 21, 2024, in the form of interim letters. A subsequent letter will follow once the remedy procedure is finalized. To facilitate communication and tracking, Subaru has assigned the recall number WRA-24, with the NHTSA campaign number denoted as 24V-227.
Subaru’s EyeSight collision detection system is a significant advancement in automotive safety technology, offering drivers an extra layer of protection on the road. The technology works by utilizing a combination of cameras and sensors that detect vehicles ahead and objects surrounding the Subaru vehicle. If the system anticipates a potential collision, it intervenes by automatically reducing engine power, helping to mitigate the force of impact and potentially preventing accidents.
