Unhappy Looking for advice (2015 ML 350 Bluetec)

Hi everyone,

I am looking for an advice before buying the Mercedes.
It would be my daily car, and I drive a lot. Usually it is 800-1000 miles a mouth.
I found one to buy 2015 Mercedes ML350 Diesel with an air suspensions and 45k miles (72k kilometers), and almost bought it but then I read a lot of bad reviews about the car. I decided to talk with some good mechanics I know. They told me to stay away from it. Some of them said that the bluetec system is not working good, some said those cars are oil leaking a lot since even new, have failure of turbo, failure of air suspensions. They told me that new problems will appear almost every day and i will get tired to fix it.

That is why I came here because you guys all around those cars and know a lot. I really like the car and how it looks. A guy who is selling the car gave me a really reasonable price. Usually cars with this price have 65-75k miles.
I am very hesitant now about buying this car after read reviews and talk to mechanics.

For example, I have now as my daily car 2015 Audi A3 TDI. I got it 3 years ago with only 38k miles , and since then this car has not give me any troubles. Only change brakes, oil and filters

I will appreciate any comments/advices.

Thanks

P.S.
I live in Vancouver, BC if this is important.

You'll hear strong opinions from both camps.
Personally, I like mine.

This place is a joke.
Run. Run far and fast. The om642 is a junk engine. The last good diesel engine MB sold in the U.S. was in 2006. And it has air suspension? Yikes. You will be dumping endless money into that car with no return on your investment except more repairs. The ML350 m276 gas engine is inherently more reliable. MB tech here for the last 21 years, 28 years total in the business. Don't do it.

Even with a such low mileage of 45k miles ?

Always believed that the Mercedes has reliable cars, as they need to maintain their reputation. But it turned out to be the opposite. Their cars are good when its new

Even then, so be careful and gather more information before making your decision. I am not a diesel guy, but I have been around the block helping others repair diesel (city transport fleet), and diesel engines are black and white to me, either they are great or they are junk (and those do not last too long). To me the word Diesel must mean bullet proof, intended to last forever; otherwise, why all that extra work and refinement to last the same as gasoline?

Also, you do not seem to have a problem with your current vehicle but seem to be looking for one. Just my 2c impression.

Thank you guys for the advices! I really appreciate it!
I decided not to go with that ML, a lot of people told me same as you said. Too many negative feedbacks.
If I have an extra space in a garage and $, probably i would buy it.

Cheers,

MB’s of all kinds.
Get a 2015. Get a ML350. Just don’t get a BT. Not worth it. A 2015 ML350 Gas will give you many years of trouble free miles. I bought my 2015 ML in 2017 for my wife and it had 22,000 miles. Now in 2023 and 45,000 I only had a recall done. Everything has been upkeep such as tires, filters and fluids. They are just a easy SUV to own with little hassle compared to a BT.

I heard about the gas 350 version that it is more reliable than diesel.
I thought about diesel only because fuel consumption is better than gas and I drive a lot.

Thank for advice

455 ft. lbs. of torque is another very real argument for the diesel; you won't see those numbers without a V8 that'll return mileage in the teens. Don't be scared of it; most of the engine is under an extended warranty and the other stuff that can fail is on the gas version also. The V8 has its own set of issues.
That said, the diesel is not a local short run grocery getter. I start mine pretty much only for trips of at least 30 miles. The gas engines are for going around town.
