The 2008 Mercedes-Benz M-Class is a mid-size luxury SUV, part of the second generation (W164) produced from 2005 to 2011. Key trims include the ML350, ML550, and the high-performance ML63 AMG.

Analysis

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

The 2008 Mercedes-Benz M-Class, while generally reliable, has some frequently reported problems. Air suspension issues are common, particularly in models equipped with Airmatic. This can lead to sagging suspension, compressor failures, and expensive repairs. Oil leaks, especially from the valve cover gaskets and oil cooler seals, are also frequently reported. Electrical issues, ranging from malfunctioning sensors to problems with the Command system, are another area of concern. Some owners have reported issues with the transfer case and transmission, particularly in higher-mileage vehicles.

Recalls for the 2008 M-Class have included issues related to fuel filter flange cracking, which could lead to fuel leaks. Owners should check the NHTSA website for specific recall information related to their vehicle's VIN. Long-term reliability can be affected by regular maintenance. Neglecting scheduled service can exacerbate existing problems and lead to more significant issues down the road. Pre-purchase inspections are crucial to identify potential problems before buying a used 2008 M-Class. Particular attention should be paid to the air suspension, engine seals, and electrical system.

How long will the 2008 Mercedes-Benz M-Class last?

With proper maintenance, a 2008 Mercedes-Benz M-Class can easily reach 200,000 miles or more. Many owners report reaching 15 years of service, showcasing potential longevity. However, longevity hinges on diligent maintenance. Key weaknesses that emerge over time include the aforementioned air suspension, which can require costly repairs. Rubber components, such as seals and hoses, tend to degrade over time, leading to leaks. Regular fluid changes (engine oil, transmission fluid, coolant) are essential to maximize lifespan. Neglecting these services will significantly shorten the vehicle's usable life and increase the likelihood of major repairs.

We bought this SUV used and I dare say that if at all possible, I would never go back to any other make. It is super reliable, I have had no major issues ( it had 109K miles on it) and it goes through snow like no other!
JP
Quite comfortable, handles well. Clean interior and love the body lines! Good acceleration, good braking. I have owned very eco friendly cars, I cannot day it gets great gas mileage but I knew that when I purchased it. Overall, great car!!
Nanz
Very nice. Smooth to drive! I purchased a used Mercedes for my youngest when he was at school and until now he is still driving it with more than 200,000 miles in it. I hope I get to drive mine that long or longer. I love it!

Not happy as the condition was nothing but a constant oil leak even after investing $1600 to fix and being told it would be another $2500 To get it stopped
Not happy
This is the most dishonest car dealership out there, please beware they will steal your deposit. They have you sign an agreement and collect money from you. They will then sell the car to someone else before you can finish the purchase and not refund your deposit. Very dishonest and not trustworthy.

What Technology & Safety Features are Included?

The 2008 Mercedes-Benz M-Class features a decent array of technology for its time. The standard COMAND system includes a central display screen, a CD player, and basic audio controls. Navigation was an available option, along with a rear-seat entertainment system with DVD playback.

Safety features include standard antilock brakes (ABS), electronic stability control (ESP), traction control, and a full complement of airbags (front, side, and curtain). Driver-assistance features were limited compared to modern vehicles, but some models included parking sensors and a rearview camera as optional equipment.

Crash-test ratings from the Insurance Institute for Highway Safety (IIHS) are generally good. The 2008 M-Class earned "Good" ratings in most crash tests. The National Highway Traffic Safety Administration (NHTSA) also provided safety ratings, which should be consulted for detailed information. Remember that safety technology has significantly advanced since 2008, so newer vehicles generally offer superior protection. Blind spot monitoring and lane keeping assist were not available features on this model year.

2008 Mercedes-Benz M-Class Prices and Market Value

When new, the 2008 Mercedes-Benz M-Class ranged from approximately $44,000 for the base ML350 to over $80,000 for the ML63 AMG. Current used market prices vary significantly based on condition, mileage, and trim level. Expect to find ML350 models ranging from $5,000 to $12,000, while the ML550 and ML63 AMG command higher prices. Depreciation is significant, as with most luxury vehicles. Factors affecting resale value include the vehicle's condition, maintenance records, mileage, and the presence of desirable options. Models with low mileage and a documented service history command higher prices. The ML63 AMG, due to its performance and rarity, tends to hold its value better than other trims.

2008 Mercedes-Benz M-Class Cost of Ownership

The 2008 Mercedes-Benz M-Class is generally costly to own. Insurance premiums are higher than average due to its luxury status and potential repair costs. Fuel economy is not a strong point, especially with the V8 engines. Maintenance and repair costs can be significant, particularly for specialized parts and labor. Expect to pay more for routine maintenance compared to non-luxury SUVs. Long-term ownership requires a dedicated budget for potential repairs, making it less economical than many alternatives.

2008 Mercedes-Benz M-Class Insurance

Insurance for a 2008 Mercedes-Benz M-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 M-Class Compare to Other Sport Utility Vehicle?

The 2008 Mercedes-Benz M-Class competed with the BMW X5, Acura MDX, Lexus RX, and Volvo XC90. In terms of performance, the ML63 AMG was a standout, rivaling the X5 M. The X5 generally offered a sportier driving experience, while the MDX provided better reliability. The Lexus RX focused on comfort and fuel efficiency, and the Volvo XC90 prioritized safety. The M-Class offered a good balance of on-road comfort and off-road capability, a niche few rivals fully matched.

Feature-wise, the M-Class was competitive, although its technology was becoming dated by 2008 compared to newer models. Reliability is a concern, with the MDX and RX generally considered more dependable. Price-wise, the M-Class was in line with its German rivals but more expensive than the Japanese alternatives.

Alternatives to consider include the Acura MDX for its reliability and practicality, or a newer Lexus RX for improved technology and fuel economy. If performance is a top priority, a well-maintained BMW X5 could be a good option, but be prepared for potentially higher maintenance costs.

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

The 2008 Mercedes-Benz M-Class is ideal for buyers seeking a blend of luxury, capability, and a prestigious badge. It's worth buying if you're prepared for potentially higher maintenance costs and prioritize comfort and a refined driving experience. It's best purchased used, as new models have significantly depreciated. Consider the ML350 for a balance of performance and efficiency, but the ML550 or ML63 AMG offer exhilarating power if budget allows. A pre-purchase inspection is crucial to identify potential issues and ensure long-term reliability. If reliability is your top concern, consider alternative brands like Acura or Lexus.

Most reliable vehicle I have ever owned!

We bought this SUV used and I dare say that if at all possible, I would never go back to any other make. It is super reliable, I have had no major issues ( it had 109K miles on it) and it goes through snow like no other!

Good Option for Section 179 vehicle

I bought this car for the Section 179 vehicle deduction as it is over 6000 lbs and therefore classifies as a truck. I bought the 2008 in 2014, so six year old at time of purchase. Rubber additive issue after 4 years. So suggest if buying used to get one 2 years tops. Expensive to maintain, but rugged on the inside. Mine still looks great after much use and a big dog.

Best SUV I have owned

Bought this car with 106000 mi used and have not been disappointed. The V8 engine is high performance and 0-60 is 5.7 seconds with the high mileage. When I bought the car the interior was like new, the seats are comfortable enough that you can travel for hours without discomfort. Only downside is cost of repairs, as you get charged more for brand even outside of Mercedes dealership that you wouldn’t on other German makes like my VW rabbit.

Rick- I own 2, stupid me on October 30, 2018

Known for problems/oil leaks

$3200 to repair the front end and now needs a $4500 repair for mail seal leak, which is a known problem with these cars. The seals are cheap but it is a 10 hour repair job, or more!

MB V-6 CDI SUV - Love it, love it!

This SUV has more bells and whistles than I could ever imagine! Ice cold A/C on command (no waiting forever for it to cool down), leather seats are immaculate, great powerful engine! Fun to drive. The convenient push-button hatch makes it easy when my hands are full. This vehicle has been very well taken care of! GERMAN Engineering at its BEST!

Just what I was looking for

I looked for a car exactly like this for approximately 16 months. With arthritis of the hip I needed to ditch the C230 Kompressor I had and move up to a SUV. I looked and monitored for pricing for a long time. I watched the prices drop and decided to see if coulter was in a bargaining position to help me out. I went, saw and drove the car and knew the price asking for this car was just up my alley. They got me a good loan with a bank and I was soon driving pain free as the challenge of getting into and out of the low sitting sedan was a issue for me. Now I just slide in and out and the comfort factor is a step up from my last Mercedes. Really enjoy the car and have already had several compliments on the car.
