Front Suspension Wheel Bearing problems of the 2007 Nissan Quest

At 60000 miles had to replace the passenger wheel bearing and abs sensor in the vehicle. At 90000 miles a knocking sound began to come from the engine while the vehicle was stopped or in park. Mechanic advised this was due to the timing chain, which is a problem due to the plastic parts that Nissan uses to hold the tension on the chain. This is a known problem with this model vehicle as numerous complainants have been filed. Concerned that Nissan knew it had a bad component and has not fixed the problem that exist. Also, now the driver side wheel bearing is bad and needs to be replaced. Started to have problems with the brakes around 30000. Fixed the brakes with oe parts, and then began to have problems with the rotors. Technician advised these problems came from the rotors getting hot. Had the rotors turned which did not work. Now I am going to have to replace the rotors on the front of the vehicle. Window motor also has went bad in the vehicle.
