Mid/rear Seats Assembly problems of the 2006 Mercedes Benz R350

May 13, 2019, my wife started the car and drove for less than a mile when her dress started smoking from the driver seat that was alight. She stopped the car and removed our 11 month old baby from the backseat and called me. She has a video of the incident. I checked on mercedes USA site and found out that there was a class action law suite on this issue. We were not notified by either mb or the administrator of the case. This could have turned out deadly as the battery is under the passenger seat and the fuel lines. I turned the car on and again , the seat started to smoke. It is now parked in our driveway as my wife and I are scared of putting our kids in it. I contacted mb USA and they directed me to the administrator of the law suite. This can create dangerous or even deadly situations if my was on a highway and could not stop or fie escalates rapidly with our child in the back seat.
