Strut Failure problems of the 2003 Mercedes Benz E500

2003 E500 with 64000mls, my front air suspension strut bottomed out failed wile driving at normal speed. Took the car to mercedes and it was out of warranty; we replaced the 2 front shocks and compressor but 3 weeks later my back shocks failed to. Total cost o repairs $3500 and still not driving alright harsh driving and lots of vibration.

Mercedes benz E500 airmatic strut collapse. Low mileage: 43000 at time of failure. Driving at highway speed when strut failed. Car leaned to right & made an emergency stop. Mercedes benz charged $1100 for replacement part, I installed. It appears to be a design flaw: protective bellows fails & contaminates air bag.
