As with all cars something will always break and Nissan is no exception. At 77,000 miles the "Service Engine Soon" light came on and was flashing in a sequence of three blinks upon which the engine started to run uneven. I then took the car to a local Nissan dealer and was told after a $90 diagnostic check that the ignition coils were bad, and was quoted nearly $700 to fix the problem, upon which I said "thanks, but no thanks". I came home got on eBay and purchased a set of nearly new coils from an '99 Infiniti I30 for $60. I popped the old ones out and popped the new ones in and viola, problem solved. I then took the car to Autozone and had them reprogram the computer so the light would go out. This was so easy to fix that my disgust for the dealer quote was intensified ten fold.
At 90,000 miles I had the CV axles replaced at a cost of $220 (very fair price) this is common of all makes with front wheel drive at this stage of use.
The original battery went at 93,000 miles, and at five years of age this is normal.
Now at nearly ten years of age the power antenna has broken, but was easily fixed by me at a cost of $12. The biggie came at 109,000 miles when the A/C compressor went out at a cost of $1100. Soon after this the radiator went out and I fixed that myself for $120.
The lesson here is if you can do the work yourself, do it, and save big money, but whatever you do, stay away from the dealer. Do it yourself or find a reputable repair man.
I know this sounds like allot, but it's not, after ten years age and over 111,000 miles she's still running strong, smooth, and straight. Keep clean oil and fluids in this car and she'll last for 500,000 miles.
