Beware of the Repair Virus

If you are interested in a beautiful looking SUV that is comfortable and will cost you more money in repairs than you have ever experienced before; then this is the vehicle for you! Here are the items you need to make sure have been replaced before you purchase one/ if they have not been replaced; plan on saving up because those dark day(s) will come. Oil cooler seals: $2500+ NOX sensor replaced if you do it yourself (1) $450 if the dealer does it over $800; note** there are two NOX sensors Shocks and struts: $2300 Air Mass Flow Sensor: $750 Regular 10k maintenance avg: $350 (always ask what is being performed) Fuel Filter: $240 Seat Belt: $750- Manufacturer defect that mercedes will not own up to. Brakes: Mercedes does not believe in rotating rotors; they replace them with the pads. What does this mean; more $$ There are probably more to come; i may find out or i may wave the white flag and try to get rid of it. I will put it to you the best way i can; i have owned a variety of diesels for over a decade including foreign diesel powered vehicles. Pass on this one; this has been a money pit compared to the 10 diesels i have owned. I have only owned this vehicle for 2 years and look how much i have spent; this is a fun vehicle to drive and has every bell and whistle; but you will pay to have the luxurious Mercedes-Benz named vehicle.

Worst reliability of any vehicle I have ever owned

The engineers who designed the vehicle did a good job. It is spacious, comfortable, quiet, has a fantastic range on long distance drives - up to 700 miles on one tank 95 liters / 26.5 US gallons. I still love driving it after almost 7 years. You can drive 800 miles in one stretch and exit the car still feeling fresh. The strong torque of the Diesel engine with up to more than 30 mpg, the transmission working seamlessly in the background, the comfortable ride, the quietness of the cabin, the excellent seats make this a wonderful vehicle. BUT THE RELIABILITY IS TERRIBLE! This is hands down the worst vehicle I have ever owned in terms of frequency and cost of repair (see below), and these cars include 2 Jeep Cherokees when they were still made by AMC. While my local dealer is very very good, Mercedes Benz of USA and the folks in Stuttgart were of no help whatsoever. Verbatim from a MBofUSA representative: "Sorry, there is nothing we can do for you. We suggest you negotiate a real good deal with your local dealer when you buy your next Mercedes." Repairs & Parts replaced on my 2009 Mercedes ML-320 Bluetec in 6 years & 10 months and 73,696 miles light duty use. 01. Factory recall: Tail lamps, rear lights, power lift gate module replaced 9cost not known) at 5,176 miles 02. Warranty work: Noise from front end; replace right front wheel bearing at 27,670 miles 03. Warranty work: Replace left strut assembly front and replace buttons on steering wheel at 32,477 miles 04. Warranty work: Removed and lubricated shift paddles on steering wheel to fix squeaky noise at 32,620 miles 05. Warranty work: Replaced defective NOX sensor at 35,866 miles 06. Warranty work: Left rear door lock assembly replaced at 42,541 miles 07. Repair NOT covered by warranty: replaced auxilliary heater in AdBlue tank diagnosed at 49,671 although it is part of the emissions control system but NOT covered by MB emissions control warranty (read the small print); paid out of some slush fund after my vociferous complaints to MBofUSA; cost estimate almost $2,200.-; fixed problem at 50,843 miles 08. Repair: Front passenger door lock assembly (same broken part as above, different door) $833.99 after 15% dealer courtesy discount at 53,277 miles; MBofUSA refuses any consideration. 09. Repair: Noise from engine department - loose NOX sensor - tightened - no charge at 56,633 miles 10. Repair: Replace 2nd NOX sensor and EGR temperature sensor and air cleaner turbo seal at 60,028 miles; this NOX sensor lasted 24,162 miles; cost of repair $1,350.92 11. Repair Turbocharger intake shut-off motor, seals, gaskets, pipes (almost left me stranded) at 66,241 miles; cost $1,675.89 12. Repair: Bad Glow Plug Control Module at 68,9921 miles; cost $503.64 13. Repair: Oil leak in front engine area. Turbo Pipe Gree O-Ring Seal and seal on oil breather assembly black o-ring seal; oil squirted on V-belt; replaced free of charge by dealer as it was possibly related to repair #11 not performed 100%; dealer otherwise very good and VERY HONEST. Same mileage as Repair #12 done at same time. 14. Replace 3 engine mounts / support struts. They were leaking fluids; at 73,696 miles; $1,774.38 15. Replace temperature sensor upstream of turbo at 73,696 miles (as in #14); cost 737.98 Estimated cost of warranty repairs $5,000+; repairs paid by owner $6,876.80 (does NOT include windshield replacement caused by stone from passing truck or self inflicted body damage); additional regular maintenance cost incl. tire replacement $8,391.98 (does NOT include registration, SMOG check, insurance, fuel); total estimated cost for all repairs, incl. warranty work, and regular maintenance ~ $20,268.78; Days in service 2491; average number of days between repairs (does not include regular maintenance trips) 166; average number of miles between repairs 4,913. UPDATE 1: The car now has 80,750 miles on it and nothing has broken since my original review. That is about 7,000 miles without something breaking, although I did have a brief scare at about 76,000 miles when the car lost power on a long uphill portion on the freeway and slowed down to about 35 mph. I managed to pull off the road [slow trucks were using the emergency lane], turned off the car, and after about 5 minutes restarted it. It has been running fine ever since. A visit to the dealer did not show any recorded error code. About 30 miles earlier I had added fuel when the tank was still half full. Maybe the fuel was dirty and caused a momentary clogging. I still love the design and how it drives very much, it is just the reliability that I hate. But I may have gotten a particularly bad one-off example. UPDATE 2: At 80,915 m replaced defective 2 front air suspension struts & air compressor & 4 new tires as a result, new turbo inlet pipe seals, new transfer case input shaft seal, incl. C-Service $7,303. 15 unscheduled stops so far not counting light bulbs. Repl. backup camera (warranty), est. $2,400 incl. module.

Have owned the Discovery and LR3 and was ready for a change. Drove the Ranger Rover Sport, X5 and ML350. Simply no comparison. The Benz is by far the best combination of luxury, performance, safety and styling for the money. We are completely blown away by the driving characteristics and features of this vehicle. It is light years ahead of its predecesor, the ML320, which was a stubby, truck-based abomination. This thing is an E-class with some ride height and storage space. If you're considering an SUV in this price range, you must drive this car. My only complaints are the position of the cruise control stalk and the learning curve on all the features. Gas mileage is as bad as the Rover.

Overall this is an excellent SUV. It's got peppy acceleration, good brakes, great looks, and is very comfortable. The interior is super nice. I love the iPhone integration, backup camera, and peace of mind knowing I have airbags everywhere. This SUV has FANTASTIC traction. It can be raining and I can pull out on an uphill incline and floor it- this thing just grabs and go's! This gives me peace of mind when my wife drives it versus our car when the weather is bad. With all that being said- it's a Mercedes. Premium fuel, expensive synthetic oil changes, and all that good stuff. Its not too bad because honestly all cars are expensive if you go to a dealer. Find a good Indy mechanic good with euro cars and you'll be fine! I had a Timing chain replaced at 80,000 miles- was told it may have needed this because perhaps the previous owner may not have changed there oil like he should have.

I brought one with 150k it’s been six month since I had owned. This car drives smoothly especially on the interstate for road trips. Gas mileage it’s not bad at all I get 19/22 mpg on the freeway. The trunk is huge with enough space also you can fold down the back seats. The rear view camera comes in clutch for this suv, navigation system works fine for a European car.

I have worked for Mercedes for over 10 years. Always known it's the safest car in the world and the craftsmenship is A+. Finally I leased one and even more excited then I could have imagined. There is no one noise at 80mph+. The stereo system with over 600watts is awesome. The suspension system with the upgrades to agility control cant be beat. It even almost makes sharper u-turns than my motorcycle. The Nav is hard drive based and is almost immediate when using. The voice control system is awesome and can even be tweaked to understand people with accents, like my wife who is from Romania.

I own 3 Mercedes Benz's. A 2006 S500 with 120,000 miles, a CLK550 with 50,000 miles and the 2009 ML350 with 53,000 miles. Out of these 3, the first 2 are manufactured in Germany. The ML is made here in the USA. The first 2 get 24-27 mpg on a long trip. The ML350 gets around 20mpg. Heres the issues. The ML is not made as well as the other 2. It has had rear hatch issues, sunroof issues (just had to replace the switch on the sunroof, cost almost $1,000) and multiple other very minor issues that always seem to cost between $500 and $1000. The cover of the drivers rear view mirror popped off. Everything functioned, but the cover would sometimes pop off in the car wash. Cost to repair $630.

I liked the 2006 ML so much I got a 2009 ML when my lease was up. The 2009 gas mileage averages around 10mpg in the city and 15mpg on the hwy. Compared to 15mpg in city and 22 mpg that i got with the 2006. The handling on the 2006 was great and fun to drive, the 2009 doesnt have steering with as much feel, it feels more like a bus. No feedback. I think the steering wheel is also bigger in this year but not sure. THe fake leather seats do not compare to the comfort of the leather seats i had previously. THe rear bumper design with the color coating is really dumb but a good way for the dealers to make extra money when you turn in the car. It scratches easily

Do not buy this model. There are way too many issues with the bluetec system. I thought I was buying reliability when I bought a diesel. I was sadly mistaken. Avoid the ml320 bluetec at all costs. I’ve spent so much money in repairs. Including a check engine light that no one can find out what’s wrong with it. Prone to leaks. Interior is great and overall style of the suv is fairly modern even in today’s standards. But, it is just not worth the reliability. Let this car die everyone so that no one else needs to make the same mistake I did.

I bought my 2009 ML350 in 2011 used (traded in from a lease) from a Range Rover dealership. I had never even thought of buying a Mercedes SUV, but it just called my name on the used car lot while my son-in-law was buying a new Range Rover. Hands down it is the best car I have ever owned! I have always traded in my cars after 2 years, but not this one! I want to drive it forever!

Traded in our Landrover and we enjoyed the LR3 while we had it. We drove all the other competitors in this price range. The general overall feel and construction of this suv will impress you. It is on a whole different level when you compare to the others. The lexus felt like a toy....We had two BMW's prior this purchase and wanted something different. I cant believe anyone would choose the RX Lexus over the MB.

Never buy a Mercedes. They are not reliable mechanically. The SUV spent more time in the shop than on the road. Diesels are not the way to go because you will have to replace the DPF filter at a cost of 4500 to 6500 dollars. Short trips the kill the DPF filter faster. That is almost half the value of the SUV. Mercedes should be sued for allowing this piece of junk on the road. I will never own another Mercedes again. The diesel engine which you can Google and read about is junk. The engine is an OM642. The engine oil is 10 dollars a quart and it drinks it at a rate of 1 quart every 1500 miles. Do the math on that one. The urea tank heater will fail which is 1500 dollars. I think it is also a bad great idea to not have a spare tire either and no place to put one.

Like many German cars, this has its quirks. The navigation is tough to get used to, but that's not what's most curious about this car: at elevation about 10,000 feet, the nav shuts off! It displays a warning and becomes inoperable. Mercedes says it affects so few people that they won't fix it. So if you drive in the mountains a lot (we live in Colorado) and want to use this car in high elevations, keep this in mind. As importantly, keep in mind that Mercedes refuses to spend the time reprogramming the nav systems. Maybe they outsourced that part to Japan...

Usually, when it comes to SUV's, I'm a Ford guy. Their SUV's feel like trucks and I like that... I never imagined myself driving a crossover. Until now. The wow factor is instant when you see this SUV. Inside and out it is just fantastic. Faster than my old V8 with better MPG's and no problem towing our 22 foot boat. I've owned a Hummer H2 in the past and I'll be the first to admit that his Mercedes is an off-road legend in hiding! I love it. It's perfect for the whole family. All 5 of us (plus 2 dogs.)

Absolutely impressed with the performance and handling. The styling is aggressive, but tasteful. The acceleration is excellent for a rather heavy "small" SUV. Steering is elegant and smooth. Shifting is excellent. A bit sluggish on an uphill during hwy cruise, but if you push on the gas it responds nicely. The nav is typical of European cars, however, it is functional and one should not be too picky. Likewise, the turn signal is a little lower on the stalk, but takes 15 min to get used to it. The gear shift is great. Electronic shift is great. All said, a definite buy!

Ive had the ML-350 for 4 weeks now with 1000 miles, performance is acceptable. I have been disappointed with the car. Few days after owning the vehicle, started the vehicle in garage, noticed two problems, 1. white smokes (only happened once). 2. Notice an engine knocks on cold start (listen carefully- make sure radio is off). Squeals noise coming from steering column and passenger driver. Drive Seat moves (under my knee) during acceleration. Rough idle. More wind noise than my Ford SUV.

I was all ready to purchase the larger GL SUV but this ML350 offered far easier driving/maneuvering plus good MPG while still providing excellent interior space. I have enjoyed this vehicle and have become aclimated to peculiarities such as low indicator location and overly complex button crazed Command system. Push the dash info button and even without the NAV turned on, the car displays the street, town and heading you are driving on. Neat. Handling, suspension is sophisticated. Loaded with 700# of big people (4), the 350 drove virtually the same as if unladen. It didn't even squat as my previous big GM SUV did when loaded. MPG has been the big surprise. It gets 17/23.

Just picked up the ML for my wife. We looked at the X5, Q7 and the MDX. The ML interior is great compared to the others. The ride is fantastic! I believe that whatever issues this car had previously-they have corrected. My wife is in heaven. She loves the seats and says they are the most comfortable she has ever had. The ride is very quiet and the handling is smooth. We are very happy with our choice.

I buy a new car about every two years and just traded in a Jeep Commander Limited with a Hemi in for this new oil burning Benz. All I can say is: WOW. This truck is the bomb, I have only driven it about 1,000 miles so far but am averaging 30mpg on the highway and about 22mpg in town. I got nearly every option, including prem packages 1 and 2 (keyless entry) and leather, etc. The ML320 is like an S class in overshoes, the ride is first rate and the gas mileage is simply amazing for such a large vehicle. The only complaint I have is that from 0-10 mph it is a little herky jerky until the turbo kicks in then it flies. The fit and finish is typical MB and is my #1 choice in a luxury SUV.

I bought this car 11/29/08 with 10 miles.This is the best car I have driven to date. The ride is smooth, excellent for long trips. Control and nav are relatively easy to use, not complex as some indicated. This is my first MB. I have 1200 miles on it so far so its too early to assess its reliability. I absolutely love this car so far.

If you never thought an SUV was for you, add the 2009 MB 320 BlueTech diesel to your list because it handles very well, has lots of room inside, is safe, lots of TORQUE and is economical mileage-wise. I have observed 22 MPG city stop/go driving.With the most conservative driving style I've observed 30 MPG highway driving in an SUV not in an economy car! Be gentle on the throttle when pulling away from stop lights and use cruise control on the highway. The turning circle radius is good and the steering for tight parking is very easy to maneuver. The front and rear parktronic option is a must. The styling of the redesigned model is a huge improvement. Very masculine. Highly recommended

Since I do a lot of highway driving, at times in bad weather conditions, I feel I need a SUV. This MB beat my previous luxury Japanese SUV hands down, in terms of ride, braking, offroad (something the previous SUV just couldn't handle)and mileage. It sure cost more but the extra cost is worth it. Mileage is very good and one can't tell that it's a diesel engine. Using the cruise control significantly enhances mileage on highways. The transmission and engine deliver power smoothly. Diesel engines beat out hybrids when hauling heavy stuff and the ML320 has class-leading towing capacity. So far, no problems with reliability. Looks like MB has fixed the problems of the previous generation.

Well it time for an update on my ML550. I put on 6,000 miles and so far not much problem to report. I had to make one stop to the dealer to date and that was for a recall notice I receive to fix some hydraulic problem and tail light seal. The truck was drop off in the morning and i picked it up about three hours later. some noticeable comments: 1) there is a click noise in the cold when you first start the car. 2) With the window down a loud noise is heard when switching from park to drive or reverse. The dealer said this is normal and is due to the large solonoid. 3) The radio went off but no display came on. The radio came back on after the vichele was turn off and back again.

Bottom line...we spent over $15,000 on repairs. So many problems with the adblue system. My ML went into limp mode and not even the Mercedes dealership mechanics knew what to do! We ended up having to junk the car. It was such a heartbreaking experience that we will NEVER purchase a Mercedes again!

This has been a wonderful driving experience .The Diesel is very smooth and quiet and the highway milage is regularly over 28 mpg with average usually around 25 including city. The interior systems are fun and easy. The lift gate is great and at the right height to the ground and the space is more than ample.

I have had this vehicle for 2 years and 5 months. Service has just finished replacing all of the front end bushings without an apparent cause for wear. 29522 miles of almost all highway miles and good roads. No off roading. After one year my gas gauge started malfunctioning. Service had to drop the tank and replace one gauge. I had a 2000ML with various problems including the same gauge issue. Nine years later and still issues that should never have happened. Mercedes service has been very good but none of these things should happen. Integrity is lacking. Too high a price to spend the time in service for things that should not fail so quickly. Transmission could shift a lot smoother.

My wife and I loved this car!! It was primarily my wife's everyday ride. The diesel was peppy and economical, although Mercedes-Benz has had some oil and turbo issues with its Bluetec engines due to engineering compromises made to meet unrealistic California emissions rules. This car would haul 13 bales of pine straw in the morning and, after a quick sweep, be an elegant ride to a dressy dinner that evening. Great on long road trips or around town, and the 115V outlet meant the blender went with us on tailgating Saturdays. Very comfortable for me, a 5'6" geezer, but equally so for my considerably taller and decades-younger wife.

Just bought the ML350 4Matic - I love this car. I'm over 6feet tall and this car is the only crossover that's built for tall people. Looks sexy and drives great - what more can you ask for.

Worst vehicle I have ever owned NOT!!! If people weren't so afraid to spend money on maintenance and repairs we Benz owners would have nothing to drive. So......,thank you. What a great engineered vehicle. Good work Benz. I'm proud of ya! Bought the car for 20k took it to Florida twice no breakdowns "mazda" Couple of repairs here and there. Whatever... It's better than replacing a transmission on a CHRYSLER!!! Yeah Chrysler Sucks. Benz knows ,Chrysler got fired from Benz in 2008. Best move to make , they try and ruin everything they touch. Lots on the never buy list. Alright, thank you Benz for engineering the BEST car I have ever owned.

We bought this to replace the 1998 ML320 we had for eleven years. The old one was great and gave outstanding reliability, but it was time to replace. This ML320 BlueTec is a great replacement and it has lived up to it's advertising. Great mileage and comfort with all the gadgets you would want. Very solid feel on the road with plenty of room for storage. We have other diesels in the family and this is one of the best. It is quiet and soot free with good mileage for the weight of the vehicle. On the road you don't even know it's a diesel. Fantastic improvement over the older diesels.

Not for family of 4 with kids

We bought the Bluetec for the fuel economy and the exterior styling. Little did we know that it is not designed for tall or larger people. I weigh 210lbs and 5'11" tall so I am not big. It is very uncomfortable to come in and out of the driver's seat. With the seat back, my kid does not have leg room from his car seat. I move the seat forward and have to drive uncomfortably. The rear entertainment is mounted very poorly in the back that my 4 year old has bumped his head hard 3-4 times. I do not recommend it for family of 4 with kids. With the 2 car seats, it is very difficult to seat 5. THe fuel economy is averaging around 24mpg which is not bad. Diesel is sufficient for daily drive.

My dad got this car as a loan while his CLK was in the shop and I felt the need to write a review for it. First, this car is very fun to drive and has great handling and performance. The rear seats are another story. The way the back doors are shaped makes you trip almost every time you get out of the back. They contour around the wheel inserts. Making for a very uncomfortable entry/exit. Just look at a side view of the car and you'll see how the back doors are shaped. It has a very well made interior and exterior. The navigation system is pretty confusing, though. It's a pretty good car overall.

Purchase this since we needed something relatively large - but were very concerned about getting a gas guzzler SUV. So far, so good - this SUV is a great solution. Getting 24+ on the highway and plenty of room and comfort. No quality issues so far, but it hasn't been long - initial build quality seems outstanding.

I have had this truck for around a month now and I am very impressed. It flat moves and is stable doing so. I purchased it to replace a 2002 C class MB that I loved but missed having room to haul anything. So far it's two thumbs up! Anxious to take a road trip in the next 2 months. Vegas to Denver should be a good test. Maybe a bit of off road testing hopefully. The gas millage isn't anything to write about at this point but it's only got 1000 miles on it. It feels like a Benz... That's the best part!

Following 10 years of ownership I can definitely say it is a tale of two cars. Power and comfort are superb... cost to maintain not so great. Expensive to maintain through MB dealership. The 642 engine could be outstanding but it is choked down with anti-pollution equipment. But despite this it averages 28 mpg and 33 hwy.

This is not a Toyota Tacoma SR5 or a Camry Hybrid.

I own a 2016 Camry Hybrid, a 2012 4x2 Tacoma, a 2012 Benz GL Bluetec, and selling after 5 years a 2009 Benz ML bluetecs, and a 2000 CLK. Have owned benz's for 50 years. The new ones are not like the old ones, lots of bells and whistles that add to comfort, luxury, and repair costs. But then my friends with Jeeps have a lot of garage time so ... Both Toyotas are reliable, boring, handle poorly, not much power, and get way worse fuel economy on a trip, even the hybrid. The Toyotas run reliably, the Benz's? If you pay attention for leaks and unusual noises. Costs: One thing for sure, go to a dealer and pay 2x what a good private shop charges for the Benz, only 1.5x for the Toyota. Drive 900 miles to Death Valley or to LA? No problem in the ML and heaven in the GL. 80 miles to Sacramento in either Toyota and I am done. And the Camry is an XLE Hybrid! What is the actual safest car in a broad range of (non-idiot rollover) accidents, and headons? Ask your State Farm Agent, check the NHTS "accident analysis" reporting. What the reports tell you is a current model ML (too few GL's) is the safest car to be in based on actual accident injuries: I saw an ML hit a Lexus: both totalled, ML occupants were fine, not the Lexus'. But the Lexus LOOKED total'ed, ML had a corner badly scrunched. A few years ago an internationally know modern dancer was hit head on on the Golden Gate Bridge. She was driving an ML and survived. The other driver did not. Have you checked the specs to see how heavy a Tesla or eMustang is? Or a eLighting Ford? With my ML/GL I get safety, good mileage, great power, and super handling. Real parts costs and service. AC out on both the Tacoma and the ML and the GL. $1500 for the GL (garage, OEM parts), $3800 for the ML (Dealer) and $4300 for the Tacoma (dealer). Air shocks: good after market shocks are CHEAPER then after market "conventional" shocks for either the Camry or my ML. Yes to those darned oil cooler seals on
