Some INFINITI QX56 owners report experiencing serious issues with rear suspension failure, particularly due to rust damage affecting the lower shock bracket. This rust can cause components to freeze, leading to bouncy and uncontrollable rear air suspensions, especially when navigating bumps. Additionally, owners have noted poor handling characteristics, such as swaying on grooved pavement and loss of control over uneven surfaces. Promptly addressing rust-related concerns is essential to prevent further damage, as a broken lower shock bracket can significantly compromise the vehicle's stability and overall performance. Therefore, it is crucial for owners to maintain their suspension systems to avoid these potentially dangerous issues.
