This briefing outlines a critical safety investigation involving Aston Martin DBX model variants produced between February 2020 and November 2025. The investigation identified a significant mechanical defect: a bolt with a reduced shank diameter that risks the displacement of the torque pin in the rear lower suspension arm. This defect presented a high risk of component failure, potential accidents, and regulatory non-compliance.

The financial impact of this issue was substantial, resulting in production losses of €450,000 per month. Through a systematic root cause analysis and a two-tiered corrective action plan, the organization successfully reduced problem recurrence by 85% and achieved annual cost savings of €180,000.

The core of the safety issue lies in a manufacturing or design discrepancy regarding the rear suspension assembly. ...
