I have spent a week searching the internet for information on the GL350 and anyone who might have issues with wind noise. It seems that anything I can find states that all the GL's are 'whisper quiet' or the reviews say there was a "touch" of wind noise but "barely noticeable."
I am sad to say that my GL seems to have QUITE a bit of wind noise. As I approach 50 mph, I immediately start to hear the noise, which seems to come from the upper part of the dash, almost as if coming from the defrost vents up there. At 65-70 mph it literally sounds as if my defrost is on a medium setting or something. In between the "solid" wind noise that never stops, you also hear "gusts" of the wind as well, even when it is not windy outside. Surely, this cannot be normal "wind noise" for a Mercedes
I had less wind noise in a 2004 Hummer H2 with 130,000 miles on it.
My question is, does this amount of "wind noise" or "wind rush" seems normal? I'm getting NO wind noise from the doors, the sunroof or the racks up top (no cross bars). It just seems as if its coming from the windshield area and honestly..it's all I can focus on, now that I know it's there. If you turn the radio up quite loud, you can eliminate it, however, I can't imagine that would be the only "fix" for this. I've had the car for about 5 weeks, I've put on about 2500 miles (I drive a lot..).
I'm tempted to go back to another dealer and drive another GL350 to see if this is "standard wind noise" I have in my GL or if I just seem to have something wrong with MINE
In my searching, I found that someone on here had a GLK and had wind noise possibly coming from a heater box, but I would have NO idea where that would be located. I'm afraid when I take this to the dealer they will tell me it's "normal" yet anytime I drive the car, hearing the "rush of wind" starting about 50mph is..just a bummer.
I did search as much as I could on this issue and couldn't seem to come up with ANYONE complaining about wind noise in the GL's. Seems as if they are usually "whisper quiet." So..I am obviously confused.
In the 5 weeks I've had the car, the engine light has already came on once,(they say it has a defective NOX sensor? they are ordering that part, from Germany), the electric up/down on the back seats stopped working within a week of owning it, and I couldn't get the right seat to go up or down.. and I found that the dealer had basically rigged the broken rear clothes hanger thing to work, it fell out on the drive home from the dealer the first day..lol (it was actually cracked and broken.) (they ordered a new one and installed that as well.) So they have fixed everything that is going wrong with it, but we sold our old SUV because every month we were at the Chevy dealer getting things fixed..so we decided to buy a new car..and voila--I am still at the dealer getting things fixed. I was hoping to avoid that with a new car!
All the above said, I really do LOVE the vehicle. I WANT to love the vehicle...but it's such a bummer when it's only 5 weeks old and you're dealing with this many issues. So..I'm hoping they can fix my wind issue--and then, all will be well.
Any help, ideas or suggestions would be wonderful. I joined your forum today!
