Service bulletin LI82.85-P-071623

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

Complaint The customer may note the following complaints: - The central display may remain dark through the entire drive cycle. The instrument cluster display will remain operational. - No audio is present from the sound system - MBUX multimedia system (A26/17) may not be shown on the initial quick test - Various other MBUX multimedia system (A26/17) related complaints Cause Water ingress through the air vent under the front passenger seat (see attached, note that the vents are facing the rear of the vehicle). As a result, the head unit (A26/17) may become damaged. Inspect the MBUX multimedia system (A16/17) hardware, including all attached wiring and connectors, for traces of water and/or corrosion (see attached picture for example). Remedy Avoid using rubber floor mats for the second row seats on which water can collect and subsequently enter the air vent under the front passenger seat. An optimized cover is now available for the air vent under the front passenger seat (see parts note). To avoid a reoccurrence of water damage, install this cover. Note: Only primary losses resulting from the ingress of fluids that can be attributed to a production error is covered by the warranty. Fluids that are introduced into the vehicle as a result of environmental influences, incorrect repairs or incorrect use by the customer are not covered by the warranty. The damage code specified in this document only applies for the installation of the fan shroud.
