What Problems Does the 2017 Mercedes-Benz CLS-Class 550 Have?
The 2017 Mercedes-Benz CLS 550, while generally well-regarded, does have some reported issues and potential long-term concerns to consider. One of the more frequently mentioned problems relates to the air suspension system. Owners have reported issues with air leaks in the suspension struts or the air compressor failing, leading to a sagging vehicle or an inability to adjust ride height. These repairs can be quite costly. Another area of concern can be the infotainment system, with occasional glitches or unresponsiveness reported, though software updates can often resolve these.
Regarding powertrain, the 4.7-liter twin-turbo V8 is generally robust, but like any complex engine, it can be susceptible to issues related to turbocharger seals or ignition coil failures over time, especially if not meticulously maintained. Fuel injectors have also been cited in some instances.
While specific recalls for the 2017 CLS 550 might vary, it's always advisable to check the NHTSA website for any outstanding safety recalls. Common recall themes for Mercedes-Benz vehicles of this era can include issues with airbag inflators ( Takata recall related), or potential electrical system faults.
Long-term reliability is a mixed bag. For owners who adhere to the recommended maintenance schedule, the CLS 550 can be quite reliable. However, the cost of parts and specialized labor for these luxury vehicles can be significantly higher than for mainstream brands, which impacts the overall long-term ownership experience. The complexity of the advanced technology and comfort features can also lead to more potential points of failure as the vehicle ages.
It's worth noting that while the 2017 model year is generally solid, specific issues could be more prevalent in earlier or later years of the second-generation CLS. However, for the 2017 model, the air suspension and potential for higher maintenance costs are the most consistent themes.

How long will the 2017 Mercedes-Benz CLS-Class 550 last?
Based on owner data and typical luxury car usage, a 2017 Mercedes-Benz CLS 550 can reasonably be expected to provide reliable service for 150,000 to 200,000 miles, provided it receives consistent and high-quality maintenance. The engine and transmission are engineered for durability, but like many German luxury vehicles, they benefit significantly from timely oil changes, fluid flushes, and adhering to the manufacturer's service intervals.
Long-term durability is strong in terms of its core mechanical components. However, weaknesses tend to emerge in the supporting systems. The air suspension, as mentioned, is a common point of failure over time, often requiring replacement of struts or the compressor, which can be a significant expense. Electronic components and sensors associated with various comfort and safety features can also become less reliable with age and mileage. If well-maintained, the chassis and body will likely hold up well, but the cost of keeping all the sophisticated systems operational can increase substantially after the 100,000-mile mark.
