这个问题是常见的。
感觉GC 有不少Mercedes基因。下面视频里提到的oil filter housing漏油，我的M B也有。大切不错的车，米国人喜欢。

刚刚又research了一下，确实是常见问题。(thanks for sharing to update my knowledge base)
特别是对于 “ hydraulic (fluid-filled) engine mounts ”：

Not really a “popular” problem in the sense that every car suffers from it, but engine mount leaks can and do happen — depending on the type of mount.

Many modern cars use hydraulic (fluid-filled) engine mounts instead of the old solid rubber style. These mounts contain a damping fluid (often glycol or a special oil) to better absorb vibrations. Over time, the rubber can crack, or the seals can wear out, and the fluid may leak.

• When it happens: usually after 80–150k km (50–90k miles), depending on driving conditions, heat, and engine vibrations.
• Symptoms: visible fluid around the mount, increased vibrations in the cabin, clunking or knocking on acceleration/braking, or a sagging engine position.
• Which cars: luxury brands (Audi, BMW, Mercedes, Lexus) and many newer mainstream cars with comfort-oriented mounts are more prone, since they often use hydraulic mounts. Cars with simple rubber mounts don’t have fluid to leak.

So: it’s not a universal “common failure” like brake pads wearing out, but on cars with fluid-filled mounts, leaks are a known and relatively common aging issue.[/i]

这个真是硬本事
