We have had a 2010 GL350 with Bluetec for over 3 years. DEF heating components, suspension, compressors, nox sensors, etc. have continually failed and the parts and labor on these things are not cheap. MB gave us 10% off when the heating element for the DEF went out just a few thousand miles after the warranty expired. They don't really care as evidenced on my E350's with Bluetec check engine light would not go off and triggered so many other codes to repair it is now ready to be scrapped and sent off the the auction in the sky. Be forewarned, MB does not stand behind these products, will not issue recalls and our most recent problem with the GL350 was smoke bellowing off the engine compartment and diesel leaving a trail on the way home. Not sure what it is this time, but am sure it will be expensive, that is a MB guarantee. My issue this time is this vehicle could have caught on fire. Yes, just like last week on the E350, I will fire off another email to MB CEO Deitmar Exler today, but don't expect too many results from it?
Stay away from Mercedes gl. This is a disaster car. I bought this car with minimal milage on it, after 50, 000, it started to fall apart. I had the following problems in 6 months: oil leak, sound stopped working, right mirror stopped working, rear suspensions made an explosion sound while I was driving, and many other problems. My mother in law had one and had many problems with it, but I thought she was just unlucky so I bought one, what a disaster. I was afraid driving anywhere because i was worried it was gonna break any time. I was ready to give it away for free because repairs were soooo expensive. The day I sold it (25000 dollars less), I felt so relieved. Stay away from this car.
This has all the required service timely and fully performed. Almost new brakes, new tires and a new diesel particulate filter. Emissions inspection for 2 years 11/09/2016. Has been well taken care of with normal wear and tear. Nav system updated 11/09/2016.
I Have sold the car for the maintenance after 160,000 miles became very expensive and on going every month or so.
Bought used GL350 and told the wife it was a Mercedes, they been making diesel cars forever. First few months, oil "o" ring goes to the tune of$1,600. Four months later timing chain stretched for about $ 3,000. Two weeks later windshield leaks and rusts connections to air bag module. $ 6,600. One month later rear wheel bearing goes bad for $800. That's over $11,000 in repairs in just over a year. Funny part is "0" rings and modules have been recalled on other 350 models. Not a happy Mercedes man.
Nobody who is looking for a reliable diesel car/ truck should buy MB GL350, which is a constant source of frustration. It is a large SUV with good fuel economy considering its size. But there is no other positive points about this car. Negative points include the following: Frequent problems with check engine light repeatedly turning on Electronics are not at all user friendly No spare tire. Although you can run on a flat tire for 50 miles but what if you are driving at night on a long drive. Traction is not the best in bad weather conditions. It depreciates faster than any other car in this range, almost 10,000 each year. Interior is spacious but not comfortable.
