RepairPal Expert Overview
An engine oil leak may develop from the area of the engine oil cooler and oil filter. This could result in loss of engine oil pressure and severe engine damage.
Nissan will notify owners of affected vehicles beginning January 19, 2012. If you are experiencing an engine oil leak, or you don't receive notification and you feel you should have, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
Some of the bolts that attach the engine oil cooler and filter to the engine may have been manufactured below specification strength. As a result, the bolt may break at the oil filter attachment point, which can cause an engine oil leak. Loss of too much engine oil can result in loss of oil pressure and the engine could seize, increasing the risk of a crash. Dealers will replace the connector bolts to correct this concern.
