Service bulletin L-SB-0024-21

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

TSB: Some 2007 ? 2022 model year Lexus vehicles in particular geographic areas may exhibit a condition where the HVAC evaporator drain hose has become obstructed with an insect nest. An insect repellent drain hose tip (ARINIX® Tip) is available to help minimize future occurrences of this environmental condition. For some models, a new drain hose is required to properly fit the ARINIX® Tip. Follow the procedures in this bulletin for proper handling and installation of this optional service part.

LSB0057222024-04-01. Service bulletin. TSB: Some 2018 ? 2022 model year Lexus vehicles equipped with the Enform? 2.0 Navigation System, require a Special Service Tool (SST) USB flash drive to update the map, points of interest, and system software. The SST is used with applicable vehicles to deliver the update, however, the process for generating license keys differs from previous generations. Before attempting to perform a map update, the expiration date of the dynamic subscription (stored in the head unit), must be checked. If the expiration date has not passed, a license key may be generated without the purchase of an activation card number (ACN). Updating the map without the use of an ACN is considered an Embedded Navigation Update (refer to pg. 10) and performing this update does not extend the subscription to dynamic map services. If the subscription period has expired, or is expiring within the next 90 days, it should be recommended to the customer to purchase an ACN. Utilizing an ACN, will initiate the Dynamic Navigation Update (refer to pg. 4). This Dynamic Navigation Update will perform the embedded navigation update and provide dynamic map services for a period of two years from the date that the Dynamic Navigation Update is performed. ACNs are provided in a pamphlet available through the normal parts ordering system. Follow the process in this bulletin to perform the update.
