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.

As you stated above the air conditioning is not a reason a driver would loose control unless you have a mercades that is leaking gas and my kids and passangers are sick and passing out and so am I. this has been going on almost 3 years. Goes to dealership and then sits because they never fix it. Finally a law suit with people having same problem entered the class action suit nothing. Took the car back and they say now the toxic gas leaking out of faulty A/C units that Mercedes was sued and consumers won but now won't fix the problem. So I now have severe asthma my kids now have breathing issues and won't drive a sick car. A/C units are to be contained and hold anti-freeze that if inhaled as it is leaking out of the non contained unit is toxic, a carcinogen, same toxin used in nerve gas and it is deadly and Mercedes does not fix it or care. This has gone on for years and is a nightmare. They made a settlement but then they don't do what the judge set forth in the settlement agreement and I am not the only one;
