Instrument Panel problems of the 2005 Toyota Scion Xb

2005 Scion Xb we have had to put three windshields in, four sets of tires and now the speedometer went out. We just spent two thousand dollars at the dealership, it had to have the seat belts done, the cruise control stuck all the time and we never got recall letters, I went on line. I am so concerned about the safety of my son. There should never be three windshield replacements, we don't know what the deal on this is and we have checked the tires daily. I appreciate the information here.

The vehicle stability control; traction control; check engine light have come on and remained on. The light was temporarily deactivated when a cam gear was replaced at wagner Toyota in lancaster MA. The error code returned and has remained on despite leaving the car at gatorland Toyota in gainesville FL on three separate occasions. The dealership service manager after first replacing the computer advised me that they do not know how to repair my car. I am uncertain whether the vsc or the traction control is operational at this time (safety concern).
