Infiniti has determined that some 2002-2003 model year Infiniti vehicles may have a defect which relates to motor vehicle safety. The engine might stop running while being driven if the crank position sensor or cam position sensor fails. This may also result in the “Service Engine Soon” light coming on or reduced engine power. If the engine stops running while driving, this could result in a crash without warning.

On some model year 2002 Q45 vehicles, the idler pulley bracket may crack and cause misalignment of the idler pulley. If this occurs, the alternator belt may slip off the idler pulley. To prevent this condition, Infiniti has initiated a Voluntary Service Campaign to install a new idler pulley bracket, spacer and bolt.

On some 2002 model year Q45 vehicles manufactured prior to March 5, 2001, refilling of the fuel tank may, on occasion, be slower than expected. When filling the fuel tank, the pump nozzle may shut off before the fuel tank is filled. If the pump nozzle shuts off repeatedly, it will result in a longer period of time to refuel the vehicle. To prevent this condition, Infiniti has initiated a Voluntary Service Campaign to replace the fuel tank on these vehicles. Use Infiniti Net to confirm if a specific vehicle is affected by this campaign (P1109).
