The external seal on the engine oil cooler can fail and create an oil leak.

The engine may stall at times due to a failed crankshaft position sensor and/or camshaft position sensor, These sensors can fail intermittently as they warm with the engine. Sensors on certain models have been recalled by Nissan and will be replaced as necessary. Please visit our recall section for this model to see if your vehicle is covered by this recall.
