Center console is not safely installed and moves while driving. Evidence is that Mercedes-bens has now twice updated the part for replacement, but does actively offer that for existing owners: Original part:166-680-16-52 1st revision part:166-680-38-03 2nd revision part: 166-680-86-04

2017 Mercedes Benz gls 450 4matic purchased September 2016. Returned vehicle to dealership 6 (six) times for foul smell coming from air conditioning unit. Foul, moldy smell still remains. Dealer has changed multiple parts, cleaned the a system and replaced dust and fine particle filter each time. The smell always comes back. Developed a recurring cough because of smell. After calling a lawyer I found out that there is a class action lawsuit regarding multiple Mercedes Benz models including the 2017 Gls450.

On Friday 11/30 my 2017 Mercedes GL450 suffered a catastrophic electronic malfunction that led to a) no ability to get car out of drive (e.g. wouldn't park, reverse, couldn't take my foot off the brake), B) no ability to turn car off, C) power steering went out, D) airbags flagged as inactive, E) most all my dashboard warning lights went on including one that said "malfunction", F) my dashboard gauges failed (e.g. no working odometer), G) the rear hatch couldn't open. This happened while driving my family -- including 2 young children -- through the desert, putting us at very great risk. My car is being serviced at mb of valencia (the closest one I could drive to). I'm being told by them that a minor, low-speed and low-impact dent in my rear bumper caused a misalignment in my exhaust, which blew hot air into the bumper and caused the blind spot assist to melt. This seems like a major design flaw -- that a small misalignment could cause a severe and life-threatening cascading system malfunction if left untreated, and that I had no warning of any kind that what appeared to be a minor dent was a major issue. I want to know if others have had this happen, and if this warrants initiating a recall investigation. My insurance company is taking photos and writing up findings. I'll provide them on request.

While driving down the turner turnpike (between tulsa and okc, around 70-75mph)the vehicle without warning has swerved left and right on three different occasions. The action felt as if the hand of god was throwing us left and then right. The car has a mind of its own. Then the last time that I drove the car it suddenly yanked me off the road without warning, literally trying to kill us. This last incident occurred when the car had around 1,750 miles on it. The thing is dangerous! I now own a car that I can't put my family in and should not be allowed on the road. The shaking originally started out as soon as I put the car on the highway for the first time, two days after purchasing it. But the shaking was only a shake that would be described as an irritant. However, in mbokc's efforts to correct the problem they may have created the two new problems which are far more troubling. Mbokc reported to me that after driving the car 600 miles they were only able to experience the problem twice. Therefore, they weren't able to fix the car unless I can get the car to preform that way all the time. It's also funny (according to the recording which I have) that they drove the car several hundred miles before they experienced the problem twice. It also waited until I drove it 1,750 miles before it tried to kill me! not sure if I should wait until an accident occurs to act. Please advise!
