OK, this is my first of many complaints on this car so be sure to check all my posts. This started out a few weeks prior to the repair. It began as a low hum, I didn't even notice it at first until a friend hopped in one day and pointed it out. IT continued to grow from a low hum to a very noticeable hum and then into almost a low grinding sound accompanied by a vibration on the floor. The weird thing was that it only was noticeable when going straight or turning left, on a right turn or curve it would cut out. I just thought it was a wheel bearing. I had some electrical work that needed to be done as well(see my other complaints) so I booked it in at the dealership. The replaced the left front wheel hub assembly at a cost of about $450. Things were good the first week but then I started hearing the low humming sound again. I though I was just hearing things at first, but after another several weeks it was back in full force. I took it back in to the dealership again and now they tell me the right hub assembly will need to be replaced. I've never owned a car that needed a hub assembly replacement, let alone 2 of them at under 100,000k. I'm getting a second opinion tomorrow.
