Analysis

What Problems Does the 2002 Mercedes-Benz M-Class Have?

The 2002 Mercedes-Benz M-Class, while offering luxury and some off-road capability, has been reported to have several frequently occurring problems and reliability concerns. Common issues include failures of the mass airflow sensor, leading to poor engine performance and fuel economy. Sunroof malfunctions are also frequently reported, ranging from sticking to complete failure. Electrical problems, in general, tend to plague these models. Rust is a significant long-term concern, particularly in regions where road salt is used. The undercarriage and body panels are susceptible. Transmission issues, especially with the 5-speed automatic, are not uncommon, with reports of rough shifting or complete failure.

Recalls have addressed various issues, including potential fuel leaks and brake light switch failures. It's important to check the vehicle's VIN for a complete recall history. Long-term reliability is generally considered below average compared to some of its competitors. The cost of parts and labor for repairs can be high, reflecting its luxury brand heritage. The 2002 model year doesn't stand out as significantly better or worse than other years in the first generation, but consistent maintenance is crucial to mitigating potential problems.

How long will the 2002 Mercedes-Benz M-Class last?

Given their age, most 2002 Mercedes-Benz M-Class vehicles have accumulated significant mileage, often exceeding 200,000 miles. Years of service can vary greatly depending on maintenance. Well-maintained examples might reach 20+ years of service, while neglected ones could be nearing the end of their lifespan. Long-term durability is a concern due to rust and electrical issues. The body-on-frame construction is generally robust, but components like suspension bushings and other wear items will likely need replacement multiple times over the vehicle's life. Proper maintenance, especially fluid changes and addressing issues promptly, is crucial for longevity.

What Technology & Safety Features are Included?

The 2002 Mercedes-Benz M-Class featured technology that was considered advanced for its time, although by modern standards it is quite dated. The entertainment system typically included a premium sound system with a cassette player and a CD player. A navigation system was available as an option, but it was rudimentary compared to current systems. Driver-assistance features were limited; it included cruise control and antilock brakes (ABS).

Safety features included front airbags, side airbags (optional), and ABS. Electronic Stability Program (ESP) was also available, which helps to prevent skidding.

Crash-test ratings from the IIHS (Insurance Institute for Highway Safety) and NHTSA (National Highway Traffic Safety Administration) provide insights into its safety performance. The NHTSA gave the 2002 M-Class four stars for driver and passenger frontal crash protection and five stars for side crash protection. The IIHS rated it as "Good" in the moderate overlap frontal crash test. Remember that safety standards and technology have evolved significantly since 2002. Optional features included a sunroof, upgraded sound system, and leather seats.

2002 Mercedes-Benz M-Class Prices and Market Value

When new, the 2002 Mercedes-Benz M-Class ML320 was priced around $37,000, while the ML430 was closer to $45,000. On the used market today, these vehicles typically range from $2,000 to $6,000, depending on condition, mileage, and location. The M-Class has depreciated significantly due to its age, maintenance costs, and known reliability issues. Factors affecting resale value include overall condition, service history, rust presence, and the operability of key features like the sunroof and electrical components. Lower mileage examples in excellent condition command a premium, but even those are relatively inexpensive.

2002 Mercedes-Benz M-Class Cost of Ownership

The 2002 Mercedes-Benz M-Class is generally considered costly to own. Insurance premiums might be moderate, but fuel costs can be high, especially with the V8 engine. Maintenance and repair costs are significant due to the vehicle's age and potential for breakdowns. Parts can be expensive, and labor costs are often higher for European vehicles. Long-term ownership requires a budget for unexpected repairs. It is not an economical choice for those seeking a low-cost vehicle.

2002 Mercedes-Benz M-Class Insurance

Insurance for a 2002 Mercedes-Benz M-Class is moderately priced, reflecting its status as a Wagon with strong safety ratings and
reasonable repair costs.

How Does the 2002 Mercedes-Benz M-Class Compare to Other Wagon?

The 2002 Mercedes-Benz M-Class competed with luxury SUVs like the BMW X5, Lexus RX 300, and Acura MDX. In terms of performance, the ML430 offered comparable power to the X5, but the X5 generally had a sportier driving feel. The Lexus RX 300 prioritized comfort and reliability over outright performance, making it a more sensible choice for many buyers. The Acura MDX offered a good balance of features, reliability, and value.

Compared to its rivals, the M-Class lagged in reliability. The Lexus RX 300 and Acura MDX were generally more dependable. Feature-wise, the M-Class offered similar luxury amenities, but its technology was becoming dated compared to newer models. Price-wise, used M-Classes are now very affordable, but the long-term ownership costs offset the initial savings.

Alternatives to consider include the Lexus RX 300 for its reliability and comfort or the Acura MDX for its balance of features and value. The BMW X5 offers a sportier driving experience but can be expensive to maintain. Unless you specifically desire the Mercedes-Benz badge and are prepared for potential maintenance, the Lexus or Acura might be better choices.

Ranks #707 SUV

Final Verdict: Is the 2002 Mercedes-Benz M-Class a Good Wagon?

The 2002 Mercedes-Benz M-Class is ideal for someone seeking a relatively inexpensive entry into the luxury SUV market and appreciates the Mercedes-Benz brand. However, it is generally *not* worth buying for those prioritizing reliability and low running costs. It's only worth considering if you find a well-maintained example with a comprehensive service history and are prepared for potential repairs. A pre-purchase inspection by a qualified mechanic is essential. The ML320 might be a slightly more economical choice than the ML430 due to its better fuel economy, but both require careful scrutiny before purchase. Don't consider this vehicle unless you can perform some maintenance yourself or have a trusted and affordable mechanic.

2002 Ml320 Very reliable.

2002 Ml320 Very reliable. I bought it used with 134K, not easy to do as most have already hit 200k , very reliable , especially if you stay on top of it with oil changes. I dropped the transmission fluid and measured how much came out. Put new gasket and filter and fresh ATF full synthetic. It dropped about 3.5 quarts of ATF , so I added 4 quarts. Runs like a dream. My ML500 had too many sensor issues, camshaft, computer issues, ignition issues, and crankshaft sensor issues, other sensors with leaks in high pressure ATF hose etc. This ML320 has been problem free for 15 months and counting. It's about to hit 140K. When I bought it used it had 136k last year. I changed spark plugs and ignition coils. 4x4 Off Road capable, snow ready, all wheel drive. Great on gas, unlike ML500 same year, wow , ate gas like crazy. Very happy with this beast in black. Best SUV Mercedes ever made. You see plenty of these out there on the road, the ML500 not so much.

Great reliability. I have the ML320 from 2002 with

Great reliability. I have the ML320 from 2002 with 135K and it drives very nice. Powerful engine picks up fast and responds with barely touching the gas pedal. With my ML500 I had a lot of sensor issues. Crankshaft, camshaft sensors etc. This one has no codes stored in the computer. Great on gas in comparison to the ML500 I previously owned. I love this truck.

All Things German on March 31, 2020

Solid but... it's a Mer$edes

I've known this car for 18 years. It's been a solid ride, and now I own it. Power everything, and I really like having heated seats in the winter. Its infinite position seats are also nice, plus it remembers my settings. I was able to use it as a camp vehicle, sleeping in the back. At one point around a 125000 miles, things started happening to it...various leaks and an overheating problem. The radio became sporadic, and it's navigation system was antiquated. Some people would say it was time to buy a new vehicle, but I decided to fix it instead. While doing that brought it back up to speed, it was not cheap. All told, I put in a little over 6k into it. Still, I love how solid it feels. It's a little tank. I feel safe in it, I feel it will go anywhere and get me out of any scrapes. That being said, I'm not enamored with its gas mileage (19 mpg), and...while its recent repairs will keep it going for quite some time, I am positive that future repairs after that will be pricey, so for that reason I would not recommend this particular SUV to a friend. Maybe one with lower miles, and ONLY if that friend likes the idea of driving a Mercedes. My next vehicle will be a hybrid or electric.

Reliable, sporty, sleak and clean SUV

SUV is comfortable, roomy and handles NJ roads very well. Pioneer in-dash navigation system with Bluetooth is great. Everything you need for a low cost SUV to get to take trips, commute to and from work and run errands. Mercedes engineering is apparent throughout.

Clean, sleak and durable. I've had it for 9 years

My ML 320 exceeded my expectations; awesome looking, comfortable, great pick up, easy to repair and great ROI; I would always recommend an ML. I am the second owner.

Best car I have ever owned

Excellent drive, reliable, spacious, fun, safe, and most importantly people can't tell that it is a 2002 model. The Germans know how to build a car that stands the test of time.
