general problems of the 2013 Mercedes Benz GL450

While driving on the freeway, we picked up a big screw in our tire which immediately deflated. To continue our journey, we wanted to replace the tire with the spare wheel. To do that, we used the floor jack that came with the car and this would have been it's first use. While attempting to lift the vehicle, the threaded bushing of this scissor type floor jack completely stripped (see picture). Not only is this super dangerous to have such a floor jack included, but if could have left us stranded for a very long time in case we would have been more remotely. I would suggest to investigate these floor jacks whether the pose any safety hazards and if make mercedes-benz replacing them free if charge.

Upon acceleration after a complete stop there are several seconds of hesitation to accelerate and loud clicking sounds that neighboring cars can hear. After doing online research, this issue is not limited to Gl450. Other owners have expressed the same concern in other models: 2008 c300, 2009 c300, 2015 c300, 07 Gl450, 03 Gl450.

Headrests on second row with easy entry option cannot be removed. Therefore, proper installation of a child safety seat (convertible car seat) is impossible. This family vehicle is unusable safely for a child.
