Pre-catalyst came apart at 95k miles after a recall supposedly fixed the problem. The pre-cat came apart and is close enough to the cylinders that it ruined the engine (the 2005+ models have the pre-cat moved farther away to permanently solve this problem). Nissan has rejected all warranty claims on any cars outside of 60k miles. $4600 to fix it. The only permanent fix is an aftermarket header that puts car out of emissions compliance.
