33100 mi	The belt tensioner was reported by the dealer as being out of specification and they fixed it under warranty. I did not know anything was wrong with the car. They found it during the regular maintenance check
49000 mi	The car was having trouble being filled with gas. There is a recall on a vent tube, but that was not the problem. There was another part, however, in the emission control system which was still under warranty that was covered they had to order the part. Will be repaired next time I am in. Not a big deal
53000 mi	They replaced a long term warranty item in the fuel and exhaust system that is supposed to help with pre-mature shut off at the gas pump. It was not the vent tube that a recent recall was issued about, but some other part. It wasn't a big deal and took just over an hour along with an oil change. Car still runs great and I really have no issues.

45000 mi US $200	Upper Radiator Hose was leaking slightly from the end of the hose. Dealer replaced.
72477 mi US $205	Had to update the ECM with new software to correct an issue where the engine would die almost immediately after starting the car. Could also result in a hard to start condition when trying to restart the car after a short trip.

21500 mi

Would go to start the car sometimes, would get all of the warning lights coming on. Engine would not start. After about 10 minutes the car would start, and not go into gear. Took in for a diagnostic check, came up with 6 error codes. Said they couldn't fix it, and go to a dealer. After 2 weeks of hell dealing with it, it hasn't happened since. So, no money paid, problem hasn't recurred, and still need to get it in to get checked out.

Check Engine Light came on. Very erratic. Very frustrating since no engine performance issue manifested. Codes referred to a possible ECM defect. Expensive repair. However dealer technician carefully investigated and diagnosed a broken wire in the harness. The repair required a soldered wire and rewrapping harness. Problem eliminated. I was actually impressed and pleased with the technician's work. It was expensive; but it required a lot of testing of wiring in the harness and in a way I was paying for the experience and knowledge of a good tech person

116000 mi US $600	So the car stalled on the highway. Worn engine mount was replaced because we heard a vibration noise within the cabin. All told $600 but no understanding of why the car stalled and we can still hear the noise in the cabin, which I have since learned may be to do with a fuel damper. Gonna live with it. $350.

56184 mi US $114	Car was choking/bucking above 2000 RPM. Check engine light on. Car was not really driveable, but a well-rated shop was a few blocks away, so I limped it over there. Code P0524, engine oil pressure too low. No freeze frame data. Oil pressure was verified ok, oil level was ok (1/2 way between low and full). Bucking was due to limp-home mode. Topped off oil, cleared codes, test drove. Problem didn’t return.
59000 mi	Car was choking/bucking above 2000 RPM. Check engine light on. Code P0524, engine oil pressure too low. Bucking was due to limp-home mode. This had happened once before. Cleared codes, test drove. Problem didn’t return for over a month.
60000 mi US $5100	Car was choking/bucking above 3000 RPM. Pending code P0524, engine oil pressure too low. Bucking was due to limp-home mode. This happened twice before, and clearing the code fixed the problem. Dealer verified faulty oil seal on rear valve timing cover, causing internal oil leakage and low oil pressure to the valve timing controllers. Seals not sold separately, so you have to replace the whole rear timing cover. Either way, a very labor-intensive job. Car was out of warranty but had very low miles, so I asked the service advisor if Nissan would pay for part of it. He checked, and they agreed to pay 20%. While dealer was replacing faulty oil seals on rear timing cover, they found evidence of coolant leakage from the coolant pump. Replaced coolant pump.

88040 mi

63000 mi	One catalytic converter failed and produced a CEL. Dealer repaired under emissions warranty.
88000 mi US $300	Oil galley gaskets failed, leading to dangerously low engine oil pressure and the car going into limp mode. Repaired it myself, so a low parts cost but a monumental amount of labor involved.

46800 mi	On one occasion, car began sputtering in 1st, 2nd and 3rd gear after a period of idling. No check engine light was displayed. Codes stored - showed faulty rear O2 sensor & cracked catalytic converter. All replaced under warranty.Issue fixed.
152000 mi US $125	Vehicle was starting to not start after ignition button pushed - everything including lights - would simply shut down. Car was jumped one time and was able to be started. Additional event occurred and car simply started an hour later. Dealership unable to detect problem; battery fairly new so that was ruled out as a problem. Issue has not recurred in last 7 weeks; no repair actually completed.
