Announcement
For Lexus (LX600/500d) Owners to reprogram Automatic Transmission ECU
Abdul Latif Jameel Co. Ltd would like to inform owners of Lexus (LX600/500d) of Customer Satisfaction Campaign on their vehicles to reprogram Automatic Transmission Computer due to the possibility that, due to an issue in the design of a certain brake clutch disc, when the transmission is shifted to the neutral position and pressure is removed from the clutch piston, the brake clutch discs will not immediately disengage from the plates, allowing some engine power to continue to transfer to the wheels. If this condition occurs when the vehicle is on a flat surface, and if the driver does not apply the service brake or the parking brake, it could allow a vehicle to inadvertently creep forward at a low speed (up to appx. 4 mph)(6.4 KM), which could increase the risk of a crash.

If this condition occurs when the vehicle is on a flat surface, and if the driver does not apply the service brake or the parking brake, it could allow a vehicle to inadvertently creep forward at a low speed (up to appx. 4 mph)(6.4 KM), which could increase the risk of a crash.
