Summary
Complaint In the instrument cluster, the symbol for "12 V battery" and the message "Switch on vehicle" may sporadically be displayed. As a consequence of this, the fault codes B1FCB97 (=> N73/3) and U116000 (=> N73/3*1) are stored in the fault memory. In the subsequent analysis of the 12 V on-board electrical system data, the following parameters are noteworthy (see picture 1 in the attachment): • Charge balance negative when stationary. • Interior CAN bus is awake for an unusually long time while the vehicle was locked. • 12 V battery SOC (state of charge) during subsequent engine start is 45% or less. NOTE: This LI does not apply if the CEL was reported as being on without a 12V message. Once the 12 V battery SOC has exceeded 50% for the first time, the symbol and the message in the instrument cluster disappear again. Cause The door control unit (N69/x) may sporadically keep the interior CAN bus awake. Remedy Update the software and coding on all 4 door control units (N69/1, N69/2, N69/3 and N69/4): • To do so, a commissioning process must be started in the door control unit, left-hand front door (N69/1). The remaining door control units (N69/2, N69/3 and N69/4) are commissioned at the same time, in an automated process.( Path: Xentry Scope; Control Units View; TSG-XX (N69/1); Adaptations; Commissioning) • The repair software has been available since 02.02.2024 and the new SCN coding since 04.06.2024. • The measures are only 100% effective if the combination of "Repair software + new SCN coding" is used. SW item numbers of the repair software: • A2069020310 for the door control units on the front doors (N69/1 and N69/2) • A2069020410 for the door control units on the rear doors (N69/3 and N69/4)

The vehicles will be visible and flagged in VMI as OPEN on April 19, 2024. Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 23 GLC (254 platform) vehicles, the regulation valve in the low temperature coolant circuit may become stuck. This would lead to a fault message in the instrument cluster. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will check the coolant valve on the affected vehicles and replace it, if necessary.

Summary
In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA, LLC ("MBUSA") is extending the warranty coverage on the HV Refrigerant Compressor & Condenser in certain Model Year ("MY") vehicles listed below from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 15 years/150,000 miles, whichever occurs first, due to the following condition: The copper wire winding in the HV refrigerant compressor might corrode over time and could cause the battery management system to diagnose a lower insulation resistance leading to an insulation error. Due to the physical connection of the HV refrigerant compressor to the HV electrical system, the insulation error would trigger a fault in the entire HV electrical system. A warning message may be displayed (e.g., battery symbol with text malfunction, without restarting engine - visit workshop, towing prohibited see owner's manual) in the instrument cluster. Both electric and combustion engine driving is possible. However, if the driver ignores the visit workshop without restarting a message and switches off the vehicle, it would no longer be able to start.
