Part of the Mercedes Benz M Class, the Mercedes ML350 started its production in 1997 and has seen various production sites, including Austria, India, Thailand, and America.
It would be later renamed the GLE Class to synergize the naming convention with other lineups.
Formally, the M class ceased its production in 2015, which led a lot of people to ask how long do Mercedes ML350 last, and that is something you should not fear as the average Mercedes ML350 will last you an average of 225,000 miles, give or take 25,000 miles depending on your care of the vehicle.
While this range of total mileage is quite respectable, it is not as much when compared to other select vehicles, which is why I will be taking an in-depth look into the Mercedes ML350 and seeing how well it can last in today’s environment and compete against other cars and vehicles so make sure you stick around till the end if you want to know everything about how long your Mercedes ML350 can last and how you can make it last even more.
What Is The Average Life Expectancy Of A Mercedes ML350?
225,000 miles is quite standard for most vehicles that you can find today, meaning the Mercedes ML350 is not doing anything special or beating any records.
The minimum you can expect from your Mercedes ML350 is about 13 years which is very respectable for a luxury midsized SUV.
However, if you give it careful attention and care, you can see it last even further, up to 16 years which is much better and more in line with what you’d expect from a company as well known and renowned as Mercedes.
Despite this, however, people are still not convinced about the lifespan of the vehicle, which is why I will compare it to other prominent cars to see how it can compete against them and if it has a decent lifespan.
Does Mercedes ML350 Last Longer Than Other Similar Vehicles?
When talking about the Mercedes ML350, many similar vehicles are in its category. Many of them have their unique specifications, features, and other things that separate them.
These differences also stack up together to provide you with different lengths of lifespan.
In this section of the article, I will directly compare the reliability and lifespan of 3 different and well-known vehicles with the Mercedes ML350 to see which car has a longer life.
To do this, I will only be taking into account the factors that directly affect the car’s lifespan to present more accurate test results that will properly determine which car can last longer and is worth getting over the other.
1. Mercedes ML350 Vs. Lexus RX 450h
The first vehicle that I will compare with the Mercedes ML350 is the Lexus RX 450h, which transitioned from a compact luxury SUV to a midsized luxury SUV in 2003.
- Despite being quite reliable, the Mercedes ML350 is beaten by the Lexus RX 450h, which boasts higher reliability ratings across various sources.
- The Mercedes ML350 has a much higher minimum life expectancy when compared to the Lexus RX 450h, but the RX 450h can reach up to 300,000 miles which are 50,000 more than the ML350.
- The Mercedes ML350 and the Lexus RX 450h have very common issues, but according to raw data, which fluctuates based on popularity, the Lexus RX 450h had much fewer issues than the Mercedes ML350.
- You cannot expect cheap repairs when talking about the Mercedes ML350, probably the most expensive car in the luxury midsized SUV category, so it is easily beaten by the Lexus RX 450h.
In this first test, it is evident that the Mercedes ML350 could not hold up to the Lexus RX 450h, which is superior in most regards and is the better choice.
2. Mercedes ML350 Vs. INFINITI FX35
The next car to go up against the Mercedes ML350 is the Infiniti FX35, discontinued in 2017, having a small run of only 15 years.
- Both of these cars can easily rank in the top 10, but the Mercedes ML350 still cannot cross the Infiniti FX35, which can more consistently reach the top 5 when it comes to reliability and longevity.
- Speaking of longevity, I believe that the Mercedes ML350 has an advantage when it comes to it as both cars can reach 200,000 miles, but there is no set estimate on how higher up the Infiniti FX35 can go.
- Following the same result as the comparison above, both the cars have very few issues, but when it comes down to raw data, the Mercedes ML350 is beaten by the Infiniti FX35.
- The same thing applies here, the Mercedes ML350 is overall $200 more expensive to repair in the year compared to similar vehicles, but the Infiniti FX35 is $200 Cheaper.
While the Mercedes ML350 may last slightly longer, it only gets this due to a lack of consistent and proper information on the Infiniti FX35, which is better in every other regard.
3. Mercedes ML350 Vs. Acura MDX
The final car to be compared against the Mercedes ML350 is the Acura MDX, available in the market since 2001 but saw a break between 2020 and 2022.
- Another tough matchup for the Mercedes ML350, the Acura MDX is widely regarded as one of the most reliable luxury Midsized SUVs, giving it a distinct advantage for reliability across multiple different platforms.
- This is reflected in how long the vehicles can last, as the Mercedes ML350 lasts 50,000 miles less on its highest mileage when compared to the Acura MDX, whose minimum lifespan is the Mercedes ML350’s highest.
- While this could easily be due to the popularity gap of both vehicles, the Mercedes ML350 has fewer problems compared to the Acura MDX, which has had a few troublesome models.
- However, these problems are much more expensive to fix in the Mercedes ML350 than in the Acura MDX, which is more than $200 cheaper.
This comparison is also lost by the Mercedes ML350, which does have fewer issues but ultimately is worse in every other category.
Life Expectancy Of Mercedes ML350 Car Parts
If you have been happy to see how long the Mercedes ML350 can last, you should know that many different factors go into its lifespan.
It is your duty as a responsible car owner to make sure all of these factors are satisfied so that your Mercedes ML350 can live as long as it can.
This will involve taking care of the parts of the vehicle. In this part of the article, I will talk about the various components and parts you should monitor when dealing with the ML350 and take good care of them.
I will also tell you how long you can expect these components to last and how you can better take care of them.
Average Lifespan Of Mercedes ML350 Brake Pads
Depending on the amount of use and the condition of both the road and the traffic, you can expect an average of 50,000 miles from the brake pads of the Mercedes ML350, which is on par with many of its competitors.
Depending on the factors above, you can get more or less 10,000 miles from the brake pads depending on how you use them.
To make sure you get the most out of your brake pads, you must try to avoid keeping your foot on the brake at all times, as this can wear out the brake pads.
You must also avoid speeding, resulting in longer or sudden breaks, which will further wear out the brake pads.
Average Lifespan Of Mercedes ML350 Battery
The battery life of the Mercedes ML350 is the same as you would expect from batteries of other cars. This would be an average of 4 years or 60,000 miles.
Similar to other components of the car, its lifespan will shift depending on how well you take care of the battery.
For that reason, you should make sure that the battery is well tightened and secured inside the car, as bumps and vibrations can cause damage or short-circuiting.
You should also avoid using the internal electrical components of the car for extended periods as they can also decrease the life of the battery by reducing its charge, which you should take care to maintain.
Average Lifespan Of Mercedes ML350 Tires
The tires have the most variation when it comes to lifespan as they will depend heavily on the owner as well as the location and setting of the car.
In an ideal setting, the tires of your Mercedes ML350 should last as long as five years which is very nice, but this can just as easily get cut down by half depending on the situation.
To maximize the lifespan of your Mercedes ML350’s tires, you should take care to avoid all sorts of speeding, off-roading, and drifting. You should try to avoid areas with a high density of traffic.
Average Lifespan Of Mercedes ML350 Transmission
The transmission of every vehicle typically lasts as long as the vehicle itself, which saves users a lot of money they would rather spend on a replacement transmission system.
Unfortunately, for some models of the Mercedes ML350, transmission failure was somewhat of a common occurrence, especially at the early stages of the vehicle.
For the most part, you should get the full 250,000 miles, but without proper care, it can be significantly lower, which is why you should regularly change the fluid of the transmission and shift as well as you can so that no issues rise up in the system.
Average Lifespan Of Mercedes ML350 Spark Plugs
As is standard for high-quality spark plugs, you can expect the ones inside your Mercedes ML350 to last well over 100,000 miles which translates to more than six years of usage before you need to have them replaced.
To keep the spark plugs healthy, you should try your best to keep the engine as healthy as possible, as it will have a direct impact on the life of the spark plugs.
Average Lifespan Of Mercedes ML350 Key Fob
The Mercedes ML350’s key fob has had some mixed reviews when it comes to how long it can last, particularly the battery of the key fob, which can last as low as one year and go up to 4 years.
This will depend on how much you use the key fob and the battery you put in it. To extend the battery, you should avoid spamming the buttons, as this reduces both the button life of the key fob and the battery.
You should only press the buttons when you are in the range of the car.
What Is Good Mileage For A Used Mercedes ML350?
Considering that the Mercedes ML350 is pretty good when it comes to durability, lasting just as long as most of its competitors, being beaten by a select few.
This gives you a lot more room to buy used models of the car as you can get them for slightly higher mileages.
Typically, you should try to get the lowest mileage you can, but in the case of the Mercedes ML350, the most optimal range to get a used car would be between 50,000 to 75,000 miles.
If you spot an ML350 that is in great condition, then you can maybe consider it in 100,000 miles, but you try your best not to go over like this.
