Cons: "Run flat tires stink, Blue tec is expensive,"

"I have owned this car for three years and love driving it and have had no problems. The only problem with this SUV is the tires and the cost of maintenance. It has run flat tires and they are terrible. If you have a flat it is very difficult finding a tire in less than a week. You cannot carry a spare because of the blue tec system. The dealer will sell you the blue tec fluid for 5 times what is cost at the VW dealer.Having a diesel does not save any money because of the tire maintenance and the blue tec. I will not buy another GL 350 CDI again."
"I have owned Yukon XL; Lincoln Navigator; Range Rover. This is simply the best SUV out there! Rides like a luxury vehicle , but yet can carry 7 in comfort. Including the 3rd row passengers! Only reason not a ten, is the navigation. MB should team with Garmin!"
"I bought this vehicle two years ago and am looking to trade it off. I loved the overall look of the vehicle and the interior has held up great, but I have had nothing but problems with it mechanically. It seems as though every month, I had to take it in for a service. Our closest Mercedes-Benz dealership is over an hour away making it inconvenient. I would think that after spending as much money as I have on this vehicle, I should have little to no problems. My husband has had to put power steering fluid in it twice, my brakes squeal, my hatch doesn't open by remote or by the outer handle. I must climb trhough the back seat and open it manually. Which is a great inconvenience in the Texas heat when you are needing to put groceries in the back or at a ball game and you need to get the cooler and you have to put the seat down and climb through the back to open the hatch. The tires do not last. Way too many problems for such a luxurious vehicle. We have owned a Lexus in the past and never had problems. I did enjoy the look of the vehicle but it did not make up for all of the minor problems we incurred."
"We purchased this SUV for the look and power. If anyone would have told me that it eats tires and brakes like a PIG, I would never have believed it. 100,000 miles and on 4th set of brakes and tiers. Now the rack sterring has broke ($3500.00 to fix). My wife drives this SUV and I drive Range Rover. Take Range Rover hands down over this SUV.
Look around before you buy this truck. If you are ok with repair bills, then this is the truck for you."
"Before I purchased my GL-450 i had a Lexus RX-350 which was a mistake because of the constant problems because of the lack of quality. Anyway, My GL-450 for my family and I has been the perfect fit. For long drives it is very comfortable even without the Premium Package and the easy third row, My previous car also had a third row but it was hard to access and not comfortable. It has a lot of storage space. This car has a lot of great features and good highway miles. Over all this is a great car"
"I bought my GL550 new in '08 in black with tan premium leather and traded in my CLK55. I got Heated rear seats, keyless go, dual entertainment screens. This car has ton of room despite the fact that the trunk is should be slightly wider. The seats heat up in 45 seconds! This car even has massaging seats! This car was loaded even without options I added! The engine is a horse! The 5,500 lb SUV goes from 0-60 in 6.5-7 seconds! The engine is super loud and in the GL550 you can barely hear it! I highly recommend this car."
"NEVER BUY a Blue-Tech. I bought this car in expectation of towing a trailer and still retain the style and comfort of a luxury vehicle. For the most part the first three years were great. Once that 40000 mile mark hit, I have had nothing but trouble. Terrible, and now as soon as I leave the shop the [Check Engine] light comes on again. What? Another $600 for a motorized intake valve. Not to mention untold other issues like $6500 for possible transition replacement. Then the Blu-Tech heating element is only sold as a combination piece with the entire unit. What $1200? Now they tell me the oil is leaking... on a Mercedes? The worst car I have ever had. Door closes like a tank, but it drops maintenance fees from my account like a rock in the ocean. Oh, and by the way my father bought the E class Blue-Tech. Same type of issues. Garbage. We have had Mercedes for years, but never again!"
"All around satisfied. Except for 2 issues. #1. The stock tires don't last more than 25K miles. Plan on spending over $1K to replace and you have limited options. Hankook is your best option with guarantee.
#2. Mercedes doesn't hold it's value as much as Mercedes likes to tout. It is a great quality car, few if any maint. issues, comfortable drive -- but depreciates just as fast as other cars. The real win is if you keep it over 7 years...then you see a difference."
"I just switched from a Lexus GX-470 to a GL 450. The ride is much better than Lexus and is more roomier. However, the instrument panel needs a major overhaul. This is the first car that requires you to read the manual just to find out how to operate the radio/CD. Once the radio is on, turning it off is yet another challenge. If I hit the power button, it turns the entire COMMAND off. The panel is over complicated. Why do I have to read the manual to operate such basic tasks???
There should be ONE button to do these things. I have to hit several buttons in the panel before anything starts."
Pros: "Comfortable, well appointed, great looking"
Cons: "Expensive maintenance"

"I love this car! I bought it in February 2010 with about 40000 miles on it and I added an extended warranty to 100,000 miles. I didn't buy it brand new because at the time my three kids were all under the age of four so I didn't want them to ruin a brand new one! I now have just under 70,000 miles and haven't really had a major issue yet. Aside from regular maintenance I've only had it in for a couple minor issues (ALL covered under warranty). The only one I specifically remember was the motor on the back door started malfunctioning so they replaced that and one of the air shocks (I think that's what it was called) had a leak so they replaced that as well.
My only complaint in this model year is that the nav system isn't as great as the newer ones and it isn't really all that great if you're searching for POI's. I literally sometimes get a location that is hundreds of miles away even thought I know for a fact there's a location within 10 miles. In case you're thinking I may need to update my nav disk, that's not it. I bought a new one about a year ago.
The only complaint I really have is that maintenance is expensive. Regular maintenance visits are several hundred dollars - pretty close to $1000. The other thing is that these cars are heavy and they go through tires MUCH quicker than I'm used to. They told me that when I bought it, but it still hurts. I just put new ones on for the second time and it runs about $1500. That's right - for the second time in 30,000 miles.
All of this said, I really do like this car a lot. It's comfortable and even the third row is tolerable for me (I'm 5'7). I wouldn't want to be back there for a cross country trip, but when my mother in law is in town I always somehow wind up in the back somewhere (that's a whole saga in itself….) Anyway, that's about it. I'm just starting to look for a replacement - more because my husband thinks I need a new car. I'm perfectly happy in my car and since my boys are getting bigger I'm considering a larger SUV (maybe an Infiniti QX56 or Q80), but since I'm losing the 5 point harness car seat in late 2014, I may just stay in the same size car and therefore I'm seriously considering a 2013 or 2014 GL."
"We've owned our GL450 for almost a year and have a little over 12,000 miles on it. We had a minor glitch at the beginning with the navigation system, but it was quickly resolved, and the only other time in the shop was for the annual maintenance where a few minor issues were tweaked (burned out light bulbs, glitchy rear hatch). Overall, we've been very happy with this SUV. The ease and flexibility of going from an 8-seat vehicle to a 5-seat with enormous cargo capacity is great, and the ride strikes a nice balance between maneuverability and comfort. It's also the quietest car we've ever owned. The only negative I can think of is the electronics (e.g., navigation and voice command) are a bit dated compared to the competition."
Pros: "expensive tires and have issues w/tire pressure"

"The GL-450 is a great vehicle. I wish the gas prices had not risen the way they did because it takes a pretty penny to fill it up. Tires are extremely expensive for it, but overall I am extremely pleased."
Pros: "Diesel, great gas mileage, large towing capacity"
Cons: "Too many sensors, expensive tires, gas cap issues"
Likely to recommend this car? (1-10): 10
"I own have owned this vehicle since new and I am on my 4th set of tires. The original factory tires lasts less than 15,000!!! Absolutely unacceptable. Only tire manufacturer is Parelli and these tires are extremely expensive. After 3 sets of Parellis I now have a set of Hankook tires and these are the best - reasonable in price, aggressive tread pattern, etc.
As for the diesel engine, it is the only way to go. I get well over 600 miles per tank. I drive from Raleigh, NC, to NYC in one tank and I do not need to refill until I am in NJ where full service gas stations offer the cheapest gasoline (and diesel) in the Eastern US.
Too many sensors on the vehicle is a curse and a blessing. Fuel filler cap does not close when the outside temperature is very high - another annoying fact.
Otherwise a fine vehicle which is aging well."
"If looking for a great big SUV this is one of the best. Traded and it brought 2/3 of its original value after 4 years! Turbo Diesel engine was flawlwss, and yielded lots of power torque and quiet sophistication, and up to 30 mpg on the highway! Amazing, understated luxury, impressive to customers I transported."
"Has had a lot of little things go wrong. Dealership near us was very good about picking car up, giving us a loaner, and fixing things quickly. It is an expensive car, but it is solid and has a lot of good features."
"I currently have 87600 miles on my 2010 GL450. I haven't had too many problems other than I had to replace the front and rear air suspension along with the air compressor about 2 years ago. My GL is currently under warranty but it will expire next month. We are having a hard time deciding whether to keep it or trade it in before the warranty expires. I've read a lot reviews where some owners have 80k miles or more. I know repairs can be costly and not sure if I want to run the risk of having something break down after warranty runs out, plus I'm still paying for it. If there was no high risk for expensive repairs, I would have no problem keeping it."
"I have the GL bluetec. I get great gas mileage and I don't find myself filling up at the pump as much. Usually I can go 10 days without getting gas. I love how much room I get and the third row seat is an actual third row seat that can seat real adults not preschoolers. I also love the rear view camera and the blind spot assist. Only draw back is the navigation is not as intuitive as I would like. Other than that, overall a great vehicle."
Pros: "Very luxurious, fast, comfortable, great looks"

"This car is amazing. Very fast on the highway and the ride comfort is superb. Accelerating is truly effortless, and for a SUV of that size I consider that spectacular. The interior is very luxurious. Leather is abundant throughout, and you also get televisions inside!! Also, there is a lot of wood trim. The exterior looks are aggressive without too much flash, just perfect. Overall, this is a great car, and the best part is it's a Mercedes-Benz!"
"owned this car since new in 2007. other than the standard maintenance have not had any issues. drives well both in the city and on the highway. Wish i had got the backup camera-this vehicle is large! Also not impressed with Mercedes and their slooowwwness to add things like usb ports, bluetooth, etc. Now that it is out of warranty, i'll be watching to see what starts to break."
"My second GL 1st 320 08 is much better than 07 37k mi and no major problems excel gas mi mid 20's at 80mph and pulls boat easily, bad elect shift put it back on middle get rid of ash tray, seats hard! All around great suv and I have had them all!"
"My husband bought me this SUV(GL-450) for Christmas last year and I LOVE IT. We have not had any problems with it. We have 3 kids and it has enough room for the 5 of us to be comfortable on long trips. It is very stylish and a head turner."
