 I traded in my car this weekend. I had owned a 2006 430S 4matic for 4 years. In that time it was trouble free for 2 periods of 6 months. Traded it in with 80k which was limited due to the multiple issues that we encountered. First the tire pressure sensors went...3 times. Next the turn signal control stick disintegrated. Next the heated steering wheel control had the same issues. The washer fluid reservoir cracked ($450).I went through a 1/2 dozen bulbs and each time a bulb goes out it disables the electrical system. The ultimate issue was the continued shaking when the car went over 50 MPH. Apparently there is a known issue with the struts, but MB will not own up to it. I almost forgot to include the A/C unit working on and off, usually in the winter. Never again!!!
