Replaced the front and back wheel bearings at a cost to me of 1500.00 after replacing the passenger side wheel bearings in 2012. This is definitely a safety issue which I addressed to Infiniti who proceeded to take no responsibility. This is just one of many in a long line of issues with this vehicle. These will be posted in subsequent complaints. Again a file was opened with Infiniti in which they addressed my complaints in a condescending manner. The fact that I have done a tremendous amount of business with Nissan/Infiniti over the years did not matter one bit. Read their mission statement on their website about the quality of their product. It is quite interesting!!
