Experiencing issues with your 2015 Mercedes Benz Gl550? You’re not alone. Many owners have reported problems ranging from annoying seat clicking noises to more significant concerns with engine and transmission mounts. Let’s delve into these common issues and what you might expect in terms of diagnosis and repair.
One prevalent issue is a clicking sound emanating from the seats. Frustratingly, this problem can persist even after seemingly expensive repairs. One owner recounted spending over $900 to address a clicking seat, which included a seat cushion replacement. While this provided temporary relief for about 300 miles, the clicking eventually returned. Dealers sometimes suggest replacing the entire seat frame or adjuster mechanism to resolve this, with quotes reaching upwards of $1500 for parts alone. Interestingly, while individual adjuster motors are available for around $300, replacement of the whole assembly is often recommended. Seeking quotes from independent Mercedes-Benz specialists in addition to dealerships can provide valuable price comparisons and potentially alternative solutions.
Engine and transmission mount issues are another common repair area for 2015 Mercedes Benz GL550 owners, often surfacing around the 70,000 to 80,000 mile mark. Symptoms of a failing engine mount can include a noticeable engine lift and drop during acceleration and deceleration. A simple test to check for a bad driver’s side engine mount involves putting the vehicle in drive, holding the brake firmly, and gently accelerating. If the mount is failing, you may visually observe the engine lifting and then dropping when releasing the accelerator. Transmission mount problems, on the other hand, can manifest as rough shifts during both upshifts and downshifts. Repairing both engine and transmission mounts can cost in the vicinity of $1500, encompassing both parts and labor.
While overall the 2015 Mercedes Benz GL550 is often praised for its driving experience and reliability, being aware of these common issues can help owners proactively address potential problems. Whether it’s a persistent seat click or concerns about engine and transmission mounts, seeking professional diagnosis and repair from trusted Mercedes-Benz service providers is crucial to maintaining the performance and longevity of your vehicle. Don’t hesitate to explore options from both dealerships and reputable independent shops to ensure you receive both quality service and competitive pricing.
