Infiniti M45 Recalls

On nearly all cars on the road today the engine idle speed is computer controlled. These vehicles are being recalled because the idle may be to low as a result of a sensor failure causing the computer to operate in the fail-safe (limp home) mode. In the limp home mode, the computer will not properly adjust for variations in the engine idle speed. As a result the engine can stall unexpectedly at idle or when coming to a stop. The sensor causing this concern is the accelerator pedal position sensor. Dealers will replace the accelerator pedal assembly and reprogram the engine control module to correct this concern.

Due to a circuit board failure, the fuel gauge may indicate a fuel level higher than what actually exists. As a result, the vehicle may run out of gas without warning, causing the vehicle to stall, which can cause a crash. Dealers will modify the affected circuit board to correct this concern.

Nissan is recalling certain 2008–2010 model year vehicles in areas of the country with heavy concentrations of road salt usage. The fastener used to secure the sensor of the tire pressure monitoring system (TPMS) may corrode and crack. If this occurs, the fastener may detach from the sensor and the TPMS light will illuminate. Dealers will replace the fastener with a more robust fastener.

Engine from the factory has had a weak lifter which begins to make noise and gets worse as the oil gets down to the bottom dot on the oil dip stick. This is how I know I am getting low on oil. At no time has an the oil light on the dash ever c...
