Since about 100k I have constantly been battling wheel bearing/hub issues. I had both fronts replaced under warranty but soon after one of my rears went. Since then they have been going one by one. So far I have replaced 4 but currently need to replace another 2. I have always serviced my vehicle at Infiniti dealerships and at $600CAD per wheel bearing/hub assembly including labour, it's becoming a little ridiculous. One of the service advisors near my home even agreed and said that the wheel bearing issue with Infiniti vehicles is something to consider when purchasing vehicles. It seems as if Infiniti really has a systemic issue with their wheel bearing/hub assemblies and seem unwilling to correct this issue. Not a good business model if you ask me.
