2007 Mercedes R350: Ownership Reliability and Common Issues

The 2007 Mercedes R350, while bearing the prestigious Mercedes-Benz name, might present owners with a less than stellar ownership experience, particularly concerning reliability. Sharing its chassis and core components with the ML and GL-Class SUVs (W164 and X164 respectively), the R-Class (W251) unfortunately inherited some of their weaknesses, especially when tasked with van-like duties.

One of the most frequently reported problem areas for the 2007 Mercedes R350 is its suspension system. Owners often find themselves replacing control arms and front struts more often than expected for a vehicle in this class. This heavier vehicle takes a toll on components designed for SUVs, leading to premature wear and tear.

Transmission issues are another significant concern. Similar to its SUV counterparts, the 2007 R350’s transmission can be prone to problems, potentially requiring costly repairs or even replacement over time. Electronics are also known to be a source of headaches, with various electrical malfunctions adding to the ownership burden.

Under the hood, the engine of the 2007 Mercedes R350 isn’t immune to potential issues either. The M272 engine, while generally robust, is known for balance shaft problems. If this issue hasn’t been addressed by previous owners, it can lead to a major repair bill, ranging from $2,000 to $4,000. This engine concern, combined with the aforementioned suspension, transmission, and electronic issues, paints a picture of potentially high maintenance costs for the 2007 Mercedes R350.

For those considering a vehicle of this type for family hauling or utility purposes, it might be prudent to consider alternatives known for superior reliability and lower running costs. Vehicles like the Toyota Sienna, for example, often present a more dependable and economical long-term ownership experience. While perhaps lacking the prestige badge, the Sienna prioritizes practicality and reliability, and benefits from a wider mechanic pool for servicing, potentially reducing labor costs.

Ultimately, while the 2007 Mercedes R350 offers a taste of Mercedes-Benz luxury in a versatile package, potential buyers should be aware of the common reliability issues and factor in potentially higher maintenance costs compared to more reliable alternatives in the minivan or SUV segment.
