2012 Mercedes-Benz GL-Class Diesel GL350 BlueTEC 4dr SUV AWD (3.0L 6cyl Turbodiesel 7A)


Review

Comfortable. Handling is just so-so. Brakes are great. Impressive towing capacity. Fuel economy is incredible - 15 towing a 6,000 pound boat; 27+ on the highway. But after spending $3,500 replacing the pneumatic suspension air pump and various parts in my E350 4Matic wagon I should have been prepared for the $4K I've now spent on the GL350. A real Achilles heel for Mercedes. Engine air pump leak and battery replacement drained another $2K. Seemed like a good buy used at $26K but after one year I'm at about $33K. Hoping the (known) oil cooler seal leaking problem doesn't occur since it's about $3K. If diesel prices weren't so low and the fuel economy so high I'd be very dissatisfied with the purchase.

My two GLs are the two worst cars we've ever owned

Review

We have had two purchased-new GLs, a gas 2007 model and a diesel 2012 model. The 2007 started falling apart almost immediately, with the ball joints and two of the air shocks dying at 15,000 miles. The other two shocks gave out within 5k miles. Our 2012 diesel was good for the first three years, but has recently been in the shop five times in four months, each time for multiple days. This has included: two air shocks dying, a replacement shock leaking, power steering pump leaking and dying, adblue heater dying, and some sort of coolant/water leak. The truck is back in again, as it has yet another leak and a clunking sound when it starts moving. Note that the oil change on these is over $1000, and the tires need to be replaced every year for $2000. We are still under warranty, but I am dumping this piece of junk when the extended warranty ends. The 2012 model had supposedly improved the problems of the 2007, but in my experience it is yet another expensive junker.

Update: The clunking sound in the 2012 GL was due to a broken motor mount. The vacuum pump was also found to be defective during this monthly repair, and was spewing some sort of oil all over the motor. There is no way I would own this car without a warranty.

***Update 2: Edmunds requested I update this review. We ended up trading in the 2012 GL, after it went into the dealership for the sixth time in 5 months, each for a different, major problem. We traded in the GL and my CLS, and got two Audis instead. I will never buy a MBZ again, and I strongly recommend you run as quickly as you can from the GL.

Review

After I brought the car home, foundout there is a long scratch on the side of window, the dealer's pre-sale service sucks, they did not even inspect the car !
After 3 weeks, the car was less than 1500 miles, the car's steelring wheel quit working during the middle of the turn, almost killed me by kissing the light pole...
I had mercedes during the 90s, I can not beleive their quality and service gone so low .
I would never buy another Mercedes.
I had a Acura RL for years and I never had any problem with it, its quality, comfort,safety and equipment are way better than Mercedes, and 20k cheaper too.


Best Features

it does get 23mile per gallon.


Worst Features

Safety is No.1 important. When I read the review about this car would go on fire by itself, I did not believe it, now I have no doubts those stories are true. For the money mercedes charge, they should at least gurantee the basic safety ! The chair are very uncomfortable, I felt carry a big heavy bag all day long when I drives it. Come on, German enginnering suppose to be the best ???
