Cabin "knock" on GLE43 Coupé...
However, one thing that we've noticed is that there is a clunking/knock sound that appears to come from the drivers side / seat area. The best way to describe it is that it sounds like there's a marble that's rolling around on the floor, and hitting a wall when it stops, making the clunking/knock sound. It's very repeatable. All you have to do is just slowly weave back and forth down the road and you will hear it "hitting" on every steering change. It also happens every time that you turn a corner into a driveway or parking lot, where the vehicle is going thru an incline.
We need to take it back to the dealer for a couple of things that we've noticed, and I'm wondering if anyone else has experienced this? I'd like to give the dealer a heads up on what the issue might be if someone has an idea.
It definitely is annoying, and needs to be fixed...
I didn't mention this in my original post, but to me, the sound seems to be coming from the drivers side B-pillar, but you're right, it could be coming from somewhere else, and just resonating there.
I just took a flashlight, and did a thorough investigation under the seat, and I didn't see anything unhooked, or loose, or out of the ordinary. All that to say, though, there is a LOT of stuff under there, and it's not exactly easy to see under there either...




I thought that it was the seatbelt system also! Dang.
Have you had yours into the dealer???

I finally got a call from another rep saying they found the drivers side seat belt faulty and are replacing it (gle63). I presume that caused the knock but who knows.
In any case, not ideal service at manhattan...
I will report back if it works or not soon

Roofliner , whole shabang had to come apart on few hundred units where the weld joints needed to be redone, along with some compound.
Hopefully it's just something simpler!!

I got a call from Krista who said in more words "too bad, you have a knock, deal with it, it's normal". Then I find out they admit there is a knock and that is not normal. They go on to replace the seat belt and hold the car a week. I get car back, dive a mile, the noise is back. They claimed to have road tested it. They must have had the music on for their joy ride because at the end they say "Excessive noise no longer present" although it is.

I had an issue of warped rotors on a previous car. They fixed them twice under warranty. When the problem came back again, they accused me of "riding the brakes", like I'm some kind of idiot. Before it was all over, I was dealing with the regional sales manager for the entire east coast! He personally sat in the car while I test drove it so he could see and feel the pulsation of the brakes and steering wheel. He acknowledged the problem and replaced the rotors again. A year or two later, the problem occurred again. I finally realized it was a design default. No matter how many times they replaced the rotors, it would only continue to happen AS LONG AS THEY WERE USING THE SAME OEM ROTORS. I found a high performance shop online. I ordered a set of third party cross drilled rotors from Canada. The problem never happened again.
OK, OK....I know I ended up coming out of pocket for the fix. But the moral of the story is this. I never gave up until they exhausted every possible remedy. The only way they could have fixed it was to redesign the part. That wasn't going to happen until the next generation of that vehicle.
