1998 Infiniti Q45 recalls (3)
Tap a recall to see the problem, the risk and the fix.
Electrical system:alternator/generator/regulator
Problem: On certain passenger vehicles, one of the diodes used in the alternator may have been damaged when built. This can eventually result in failure of the diode and an electrical short which could melt the plastic housing.
Risk: If the combustible gas emitted by the melting plastic does not disperse due to air flow through the engine compartment, it could ignite and in turn ignite the fan guide in the alternator.
Fix: Dealers will replace the alternator. Owner notification began july 29, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact nissan at 1-800-647-7261 or infiniti at 1-800-662-6200.
Electrical system:alternator/generator/regulator
Problem: Vehicle description: passenger vehicles. One of the diodes used in the alternator may have been damaged when built. This can eventually result in failure of the diode and an electrical short which could melt the plastic housing.
Risk: If the combustible gas emitted by the melting plastic does not disperse due to air flow through the engine compartment, it could ignite and in turn ignite the fan guide in the alternator.
Fix: Dealers will replace the alternator.
Power train:automatic transmission
Problem: Vehicle desription: passenger vehicles. The ignition key can be removed when the engine is turned off without placing the transmission shift lever in the "park" position. This does not comply with the requirements of fmvss no. 102, "transmission shift lever sequence, starter interlock, and transmission braking effect."
Risk: If this occurred and the driver failed to move the shift lever to 'park' or engage the parking brake, the vehicle could roll away if parked on a slope.
Fix: Dealers will replace the shift lock control unit.
