The defect centers around the possibility of damaged UCA pinch bolts due to a fault during vehicle assembly. If the UCA pinch bolt is compromised, there is a risk of a loss of clamp load between the UCA ball joint and the knuckle. The consequences could be severe, leading to the separation of the UCA from the knuckle and, subsequently, the wheel falling outboard. This poses a significant safety risk, potentially resulting in a vehicle crash. As a warning, owners may watch out for abnormal noise when driving over bumps as a warning.
