What Problems Does the 2008 Mercedes-Benz R-Class Have?

The 2008 Mercedes-Benz R-Class has several frequently reported problems. Air suspension failure is a major concern, with components like the air struts and compressor prone to malfunction, resulting in expensive repairs. Oil leaks, particularly from the valve cover gaskets and oil cooler, are also common. Electrical issues can range from minor sensor malfunctions to more significant problems affecting the vehicle's systems.
Transmission problems, including rough shifting and failure, have been reported by some owners, though not as frequently as the air suspension issues. Recalls for the R-Class have addressed issues like fuel filter flange cracking and potential problems with the fuel pump relay.
Long-term reliability is a concern due to the complex nature of the vehicle and the potential for costly repairs. Earlier model years (2006-2007) may have more prevalent issues due to their age. Thorough maintenance records and pre-purchase inspection by a qualified mechanic are crucial to identify potential problems before purchasing a used 2008 R-Class.

Long-term durability is a concern due to the aforementioned air suspension, electrical, and oil leak problems. These issues can become more frequent and costly as the vehicle ages. Regular fluid changes, timely repairs, and careful attention to warning signs are essential to maximizing its lifespan. The R-Class requires proactive maintenance to avoid major failures.

What Technology & Safety Features are Included?

2008 Mercedes-Benz R-Class Insurance

Insurance for a 2008 Mercedes-Benz R-Class is moderately priced, reflecting its status as a Sport Utility Vehicle with strong safety ratings and
reasonable repair costs.

How Does the 2008 Mercedes-Benz R-Class Compare to Other Sport Utility Vehicle?

The 2008 Mercedes-Benz R-Class competed with vehicles like the Acura MDX, BMW X5, and Lexus RX. In terms of performance, the R-Class, especially the R550 and R63 AMG, offered competitive power. However, its handling wasn't as sporty as the BMW X5.
Regarding features, it matched its rivals with available luxury amenities, but its technology was becoming dated compared to newer models. Reliability is where the R-Class falls short compared to the Acura MDX and Lexus RX, which are known for their dependability. Price-wise, used R-Classes are now more affordable, but potential repair costs offset the savings.
Alternatives to consider include the Acura MDX for reliability and a more engaging driving experience, or the Lexus RX for a comfortable and luxurious ride with better long-term dependability. The Buick Enclave offers similar space and features at a potentially lower overall cost of ownership. While the R-Class offers a unique blend of luxury and space, its reliability issues make it a less compelling choice than its rivals.

Final Verdict: Is the 2008 Mercedes-Benz R-Class a Good Sport Utility Vehicle?

The 2008 Mercedes-Benz R-Class is ideal for buyers seeking a luxurious and spacious vehicle with available all-wheel drive, who are willing to accept potentially higher maintenance costs. It's worth buying *used* if thoroughly inspected and well-maintained, preferably with comprehensive service records. The R350 offers a balance of performance and fuel economy, while the R550 provides more power. The R63 AMG is for enthusiasts willing to pay a premium for performance.
However, potential buyers should be prepared for air suspension repairs, electrical issues, and other costly maintenance items. If reliability is a top priority, alternative vehicles like the Acura MDX or Lexus RX are better choices.

Bought it when it was already 7 years in service.

A great car with so many safety features and best value. Spacious interior and stylish exterior. I own a V6. It’s a pretty heavy car so V8 maybe better than V6?

Has all the options one could ever need.

I love the look and the six are the most comfortable out there!!! Most cars only fit four comfortably the fifth is squeezed in the rear seat. Most SUVs too boxy.

Lots of car for money

Overall great car. Sad it's discontinued. Lots of vehicle for the money. Extremely comfortable for 6 people. Not a lot of cargo if fully loaded with passengers but all in all worth the money.

Excellent 7 seat car. Does't look like a minivan.

The car is great. All 7 seats are adjustable. Very comfortable inside with 7 passenger, or very spacious with just 5 passengers. It has plenty room even on the 3rd row.

Love the space

This car might all of our needs. We're looking for a larger family vehicle that we could fit our two car seats in and still have some cargo room. This vehicle has fit all of that and more.

This is the most versatile car/SUV for the $$

This car has tons of room. All rear seats can be folded flat for hauling big items. The AWD is a bonus! Very easy to get around
