Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain
subject vehicles, the Electronic Ignition Lock control unit coding does not correspond to current series
Issue production configuration. As a result, battery management could be affected and cause low battery
voltage. A 12V battery message may appear in the instrument cluster after the vehicle has been
dormant for an extended period of time.
MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will SCN code the
Remedy Electronic Ignition Lock control unit. The new SCN coding improves battery management, improving
the efficiency of the 12V electrical system.
Launch Date Affected VINs will be flagged as “OPEN” in VMI on Friday, September 26, 2025.
Warranty Claim Notice

Please note the campaign will close after the warranty claim has been submitted. This change can
take at least one-day to reflect in NetStar VMI.

While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle quality and
customer satisfaction. Please refer all customer inquiries to the Customer Care Center at 1-800-FOR-MERCEDES.
