high-pitched whistling sound
Pick up the GLS450 in May and started to hear these whistling noise when I am going over 100km/hr, I did a lot of search (thanks to the forum and this threads), I tried the 3M tape, the O rings, neither of them worked. so I came across with some YouTube videos about similar issues with Volvo and Lexus, what they did to fix this problem is to use the cabinet door bumps. it worked! We drove over 1,200km the past week for road trip and the noise is gone. I agree this issue is design flaw and something to do with aero dynamic. so, here are the pictures! I basically stick the bumps all around, but I will slowly take them off one by one, and pinpoint which area really caused the issue. here are some pictures. hope this will help everyone until MB has a permanent fix.
The Best of Mercedes & AMG
I am waiting until March to bring my GLE in for its first service, I am hopeful by then that they will have their act together and immediately order the replacement cover. I also hope that the painting of the cover looks perfect and is indistinguishable from the body color. My GLE is white so I am not anticipating any issues.
Thanks for the part # , this way I can give it to the service advisor just in case he attempts another remedy for this annoying problem.

That being said, MB needs to step up its game in the area of customer service as well. My dealership has been always fair and I believe honest with me, my very limited experience dealing with MB corporate customer care left me somewhat unimpressed. Again, it was a one time call.
The American auto manufacturers vastly improved their product because of the superior quality and customer service of the Japanese manufacturers. The Japanese initially entered the market building tiny econocars, they gradually moved to somewhat larger cars, never sacrificing their build quality. Now they dominate, or have a huge presence in every segment, cars, luxury cars, sport cars, trucks and SUVs.
Mercedes does have a certain panache which IMHO, was not felt by me when test driving a Lexus. My wife who does not know anything about cars came away with the exact same feelings after our test drives. Today, when almost all cars are quite reliable, the little things become more prominent. I never heard a Lexus owner complain about how he was treated by Lexus, unfortunately I cannot say the same thing about a MB owner. Have a healthy , safe, and Happy New Year.
