2012 Infiniti M35h

Issue: 
On certain vehicles, the driveshaft may not have been manufactured properly. As a result, the driveshaft could break and cause a loss of power to the wheels. Additionally, if the vehicle is parked and the parking brake isn't applied, the vehicle could roll away. 
Note: This recall only affects two-wheel-drive (2WD) models. 

Safety Risk: 
A loss of power to the wheels could increase the risk of a crash. A parked vehicle that rolls away could also create the risk of an injury or a crash. 

Corrective Actions: 
Nissan will notify owners by mail and advise you to take your vehicle to a dealership to replace the driveshaft.

Issue: 
On certain vehicles, the propeller shaft (driveshaft) could break while driving and cause a loss of power to the wheels. In severe cases, a propeller shaft failure could also damage the parking brake. If this happens, there may be no way to stop movement of the vehicle when it is parked. This could allow the vehicle to roll away. 

Safety Risk: 
A loss of power to the wheels or a vehicle rollaway could increase the risk of a crash. 

Corrective Actions: 
The company will notify owners by mail and instruct you to take your vehicle to a dealer to replace the propeller shaft.

On certain vehicles, the fuel pressure sensor connected to the engine fuel delivery rail may not have been sufficiently tightened during vehicle assembly.  Should the pressure sensor loosen, fuel could leak past a gasket used in the connection between the sensor and the rail.  Fuel leakage, in the presence of an ignition source, could result in a fire causing property damage and/or personal injury.  Correction: Dealers will inspect the pressure sensor and tighten to specification.  Note:  This is an expansion of recall 2012-074.  Vehicles that were repaired under the previous campaign are not affected because that remedy would have corrected the subject condition.

On certain vehicles, the fuel pressure sensor connected to the engine fuel delivery rail may not have been sufficiently tightened during vehicle assembly.  Should the pressure sensor loosen, fuel could leak past a gasket used in the connection between the sensor and rail.  Fuel leakage, in the presence of an ignition source, could result in a fire causing property damage and/or personal injury.  Correction: Dealers will inspect for fuel leakage from the pressure sensor and the fuel rail.  If there are no signs of a fuel leak, the fuel pressure sensor will be tightened to specifications.  If a fuel leak is confirmed, the gasket between the sensor and the fuel delivery rail will be replaced, and the sensor will be tightened.

On certain vehicles, the engine oil cooler stud (onto which the oil filter is mounted) could fail.  This could cause an engine oil leak, which could illuminate the instrument panel's engine oil warning lamp.  Abnormal noise and rough engine performance may also be noticed and, in the worst case, the engine could fail and stop suddenly while the vehicle is in motion.  Engine failure would result in lost vehicle propulsion which, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury.  Correction: Dealers will replace the engine oil cooler connector stud.
