Cadillac XTS strut leaking issue requiring replacement, common in other GM vehicles on Cadillac XTS

Some Cadillac XTS owners report experiencing issues with leaking struts, which can indicate failed internal seals leading to oil leakage. Additionally, there have been reports of rear suspension not holding air, potentially related to these leaking struts or other suspension components. In some cases, owners have noted locked struts after the vehicle was jacked up for an extended period, although adjustments may still allow movement. Furthermore, specific instances, such as a service suspension code in a 2016 XTS Premium indicating the need for front left strut replacement, highlight the potential necessity for strut replacements in XTS models. These concerns underscore the importance of timely inspection and maintenance to address strut-related issues in Cadillac XTS and other GM vehicles.
