Problem overview

Some Cadillac XTS owners report experiencing issues with leaking rear shocks even after recent replacements. These leaks can stem from various causes, including worn-out seals, rough terrain, or dirt entering the shock absorbers. Symptoms such as fluid leaking from the shocks, thudding noises over bumps, and sagging can indicate the need for immediate inspection and potential replacement. Owners are advised to address these leaks promptly to prevent further damage and maintain optimal vehicle performance. Proper diagnosis is essential to determine whether the leakage is due to normal seepage or a defective component, as unnecessary replacements should be avoided. Additionally, if the shocks continue to leak oil shortly after installation, it may suggest problems with the quality of the shocks or the installation process, prompting some owners to consider switching to regular shocks if the magnetic ones are not performing well.
