20230210AIR BAGS

The seat occupancy sensor on the passenger seat of this car is malfunctioning. This is a RECOGNIZED PROBLEM for Mercedes cars. There are numerous websites and YouTube videos describing this problem, offering replacement sensors, offering bypass kits and describing how to make this repair. (Please see attached for small sample). But Mercedes does not acknowledge this problem and has not responded to correspondence about the problem. Instead, the local dealer has said that it will cost >$1,000 to diagnose the problem and that they will probably have to replace the entire bottom section of the seat, which would cost at least $5,000 for parts and labor. This problem WILL cause the child safety seat feature to malfunction and may keep the passenger side airbag from deploying in a collision. The consumer stated the seat occupancy is defective and the parts are not available for his vehicle.
