Found a small oil leak at around 55,000 miles. Didn’t worry about it for two oil changes. Forgot that there was a 60k Powertrain warranty. Nissan diagnosed an upper oil pan gasket failure that is “common” on this engine. $2500.00 in repairs and 5 days later all is good. Thank God for an extended warranty. This should not happen at mileage this low, especially when the service advisor knew exactly what it was within 2 minutes of my arrival!
