Hello, I am driving 2013 3.6R Outback since Fall of 2012 bought brand new. Mostly highway miles, occasional trips to the mountains, ocean beaches and national parks. I maintain my car very well and so far had not have any problems. At about 64K miles I started to hear constant humming noise coming from the front of the car on its both sides. I have a set of hard rubber Firestone tires. So initially I attributed this sound to the tires rubbing against the road. But this noise was becoming louder at higher speeds. After it became unbearable to my nerves, I took my car to the dealership. They determined that both of my front wheel bearings are bad and need to be replaced. Even though my car's drive train warranty has expired, I called SOA and insisted that it is highly unusual for the wheel bearings to go out in just 60K+ miles. It must have been a latent factory defect that slipped through their QC. I drove a 1999 Mercury Sable wagon before this car for well over 200K miles without any problems related to the wheel bearings. To their credit, SOA agreed to pay for fixing this defect as their act of good will. Otherwise I would have to spend around $724 out of my own pocket. I intended to keep this car for as long I could based on its reputation for durability and longevity. But now I have a reasonable concern, for how long can I drive my Outback before similar problem occurs with my rear wheel bearings or reoccurring with the front ones? Could somebody share their thoughts or suggestions on this matter?
