Mercedes-Benz GLS550 air shocks lowered issue in rear suspension on Mercedes-Benz GLS550

Some Mercedes-Benz GLS550 owners report experiencing issues with the rear suspension, particularly related to lowered air shocks. These problems may stem from air leaks in the suspension system, which can lead to the rear suspension unexpectedly lowering over time. Additionally, cold weather can exacerbate the issue, causing the suspension to sink more noticeably overnight. Some owners have noted that minimal leakage in the rear struts may also contribute to this lowering problem. It is advisable for owners to seek a professional inspection of the air shocks and suspension system to identify any leaks or damage. As a potential solution, some GLS550 owners consider converting the air suspension system to passive shocks and coil springs for a more affordable fix. For maintenance and repair, using genuine Mercedes-Benz parts is recommended to ensure optimal functionality, while Arnott aftermarket parts may be considered for front air shock replacements to maintain the suspension system's performance.
