I was pulling up the passenger seat to put something in the backseat of my parked car. The headrest unexpectedly deployed and a small plastic piece broke off. Now I am fearful this could happen when driving the car, potentially harming myself or others. A witness saw what happened. There was no warning.

1. oil leak from the oil cooler assembly in the diesel engine. Obviously, a cheap gasket was used to seal it! mb, with diesel experience of over 80 yrs, should know by now what material they use in their diesel engine. This defect will develop in every car they made in the same way and they should recall the cars and correct the issue 2. the driver seat is torn along the tuft in the seat.this is happening across the board ion all mb cars using the same materials. Again, it is a material issue and should be corrected. Old mb seats lasted for decades!
