Safety Recall Campaign – Stop Lamp Switch - 4526K

Lexus RX330 (MCU38)

Published: 24 May 2021 – Operation Code: 4526K

BACKGROUND

Investigations by Toyota Motor Corporation have determined that a requirement exists for the initiation of a safety recall
campaign to be conducted in accordance with the FCAI Code of Practice for safety related recalls, affecting a range of
Lexus RX330 vehicles.

DESCRIPTION OF PROBLEM

In the subject vehicles, a build–up of silica within the stop lamp switch from airborne silicone within the vehicle cabin results
in poor electrical conductivity across the switch contact points. In the instance where this occurs, there is a possibility that
the stop lamps may not illuminate and in some instances the ABS / TRC warning light may come on. Additionally, the shift
lock may not disengage and allow the shift lever to move from the “P” (Park) position.

When this failure occurs, the manual override on the shift lock is required to remove the transmission shift lever from the “P”
(Park) position.

Some owners may not have experienced these conditions however it is mandatory that all vehicles are actioned per this
Safety Related Recall Campaign.

INVOLVED VEHICLES

OWNER LETTER – LEXUS STOPLAMP SWITCH

Dear Lexus Owner,
Thank you for having purchased your Lexus RX330 and we trust that it has fully met

your expectations. We are dedicated to providing vehicles of outstanding quality and
value, and as part of our constant efforts to provide the best in customer satisfaction,
Lexus is announcing a Safety Recall Campaign that includes your vehicle.

Investigations by Lexus reveal that under certain environmental conditions, the
electrical contact points in the stop lamp switch can be affected by a build-up of
silicon oxide causing an electrical resistance within the stop lamp circuit. The
reduced current flow can result in the stop lamps failing to illuminate, thereby not
signalling to other motorists that the driver intends to slow down or stop.

Vehicles produced between October, 2002 and July, 2004 are potentially affected by
this condition.

Our records indicate that your Lexus RX330 was manufactured during this period
and that it falls within the range of vehicles that require the stop lamp switch
replaced. We therefore request that you make an appointment with, and present your
vehicle to your Lexus Dealer without delay.

Rectification is free-of-charge and can be carried out by any Lexus dealer. The
labour time for the repair is approximately one hour, however, depending on the
dealer’s work schedule, it may be necessary to make your vehicle available for a
longer period of time. Please present this letter to the dealer when you take your
vehicle in for rectification.

If you no longer own this vehicle would you kindly complete the enclosed postage
paid form providing Lexus with the name and address of the new owner (if known).
If you have any queries regarding this Safety Recall Campaign, please contact your
nearest Lexus dealer or the Lexus Customer Support Line using our free call number
1800 153 987 between 8:00 am and 4:30 pm Monday to Friday (E.D.S.T.).

Lexus sincerely regrets any inconvenience caused by the need for this action which
has been taken in the interest of safety and continued customer satisfaction.

Yours faithfully,
Lexus Australia
