2003 Infiniti M45 Recalls
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.
The circuit board for the crank position sensor and cam position sensor may have improper solder joints. This could cause the Service Engine Soon lamp to come on, the engine may not start, you could experience reduced power, or the engine may stall without warning, which could result in a crash. Dealers will replace the the crank position sensor, cam position sensors, and in some cases, the variable timing control sensors. The recall began on December 22, 2003. The Nissan recall number is R2022 and the Infiniti recall number is R3021.
2003 Infiniti M45 Reviews
LOVE this car... brake rotors warped (improper lug nut tightening or heat?) but replaced them with drilled rotors and have had no other issues. Only repair in seven years and 75k miles has been an EGR sensor. Looking at suspension maintenance soon, and wishing there were more aftermarket upgrades around for this model.
