| Feb 201756184 miUS $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. | ||
| Mar 201757000 mi | “Key” warning light was on. Not related to the key battery, it indicates a problem with the immobilizer or keyless starting system. There were no obvious symptoms besides the light, and it turned off eventually. | ||

| Sep 201760000 miUS $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. | ||
