Infiniti FX35 and FX45 Wiring Problems
1. ABS Sensor Problems:
A common problem with the ABS sensors was the ABS malfunction indicator on the dashboard. The sensors located on the wheels could fail due to dirt, corrosion or wear, which would affect the operation of the anti-lock brake system.
2. Parking Sensor Problems:
Parking sensors (if installed) would sometimes not work properly, especially in bad weather conditions or after washing the car. These sensors could incorrectly determine the distance to obstacles, which would result in false alarms.
3. Light Control Unit Problems:
Some owners complained that the headlights, especially the xenon ones, would suddenly go out or flicker. This could be due to defects in the light control unit or faulty wiring.
4. Door Wiring Problems:
The wiring inside the doors (especially the driver's door) could wear out over time, causing the power windows, heated mirrors, or central locking to fail.
5. Battery and Alternator Problems:
There have been cases where the battery would discharge faster than usual due to wiring or alternator problems. In some cases, the alternator would not provide a stable charge, causing the battery to discharge and electrical problems in the car.
6. Fuel Gauge:
The fuel gauge would often fail, causing the dashboard to display incorrect information about the amount of fuel in the tank. This resulted in drivers being unable to accurately determine how much fuel was left.
7. Air Conditioning and Climate Control Problems:
There have been problems with the electrical components of the climate control system, especially the blower fan and temperature sensors. Sometimes the system would start to malfunction, causing the air conditioner to turn off or the temperature to be inaccessible.
8. Engine Control Unit (ECU) Issues:
Some owners have reported issues with the Engine Control Unit (ECU), which can cause performance issues, rough running, or sudden engine shutdown.
9. Tail Light Wiring Issues:
Tail lights, especially the brake lights, sometimes fail due to poor connections or worn wiring. This can cause visibility issues for other drivers and can result in fines.
10. Key and Keyless Entry Issues:
Some models have had issues with the keyless entry system and engine starting. This could be due to issues with the signal from the key or issues with the ignition control unit.
