LEXUS LEXUS RX 400H UK Recall Check

---

Recalls Number (Vehicles Effected)

R/2013/104 (9649)

Manufacturer Reference

Defect

It is possible that due to variations in the build specification of the Intelligent Power Module (IPM) which includes the Insluted-Gate Bipolar Transistors (IGBT's) the lead-based solder could be affected by abnormally higher operating temperatures. This could result in a degrading of the solder and eventually heat damage to the IGBT's. If this occurs then warning lights on the instrument panel will illuminate. However if the driver fails to heed these warnings or the main power supply fuse blows then the vehicle could stop without warning.

Remedy

Recall all the affected vehicles and replace the IPM unit with a upgraded unit.

R/2011/150 (4162)

Manufacturer Reference

TBA

Defect

Due to a none conformance to specification the front crankshaft pulley inner and outer rubber mounted section may separate. If the separation occurs noise will become apparent the ignition warning lamp may illuminate and in the worst case the power steering drive belt may detach from the pulley which will result in the driver having to significantly increase their effort to steer the vehicle especially at low speed.

Remedy

Recall the vehicles that are likely to be affected to check and where necessary replace the crankshaft pulley.

Recalls Number (Vehicles Effected)

R/2011/076 (4007)

Manufacturer Reference

1KBA-044

Defect

The Intelligent Power Module within the inverter system may fail. This will result in various warning lamps being illuminated. In most cases this will result in the vehicle entering the fail-safe mode resulting in limited power. In limited instances the fuse on the power supply circuit could blow resulting in the hybrid system stopping.

Remedy

Replacement of the Intelligent Power Module (IPM) in the inverter assembly.
