2021 Mercedes-Benz AMG GT Front Diffuser Campaign Deactivation

Why This Matters

Mercedes-Benz has identified that the front diffuser on certain 2021 AMG GT Black Series vehicles may not meet current production specifications. This issue prompted Service Campaign 2023030016, which has now been temporarily deactivated. While the campaign is paused, owners cannot have the necessary repair performed, potentially impacting the vehicle's intended aerodynamic performance.

The temporary deactivation means that new work instructions are being developed. Until the campaign is reactivated, the remedy for the AMG GT front diffuser issue is unavailable. Owners should be aware of this status and understand what steps they can take while awaiting reactivation.

What's Being Addressed

This service campaign, identified as 2023030016 (internal campaign description 22P8891008), concerns the "Check Front Diffuser Attachment Point Seal." Mercedes-Benz AG (MBAG) determined that this component on affected vehicles might not meet the required production specifications. The campaign specifically applies to 379 Model Year 2021 GT Black Series vehicles, which are built on the 190 platform. These vehicles were initially flagged in the Vehicle Master Inquiry (VMI) system as "OPEN" on April 28, 2023.

Campaign History and Deactivation

The "Service Campaign Update Notification" issued on July 21, 2023, confirmed the "Temporary Campaign Deactivation" of Campaign 2023030016. The campaign was formally deactivated on July 18, 2023, because the original work instructions were deemed insufficient, and new, revised instructions are currently being developed.

Mercedes-Benz anticipates that the campaign will be reactivated around mid-August 2023, once these new work instructions are issued to the field. Until then, the remedy for the AMG GT front diffuser issue remains unavailable.

Important Warnings for Owners

Mercedes-Benz has explicitly stated that the campaign was deactivated on July 18, 2023. At present, the remedy for the AMG GT front diffuser issue is not available. This means that dealers cannot perform the necessary repairs or provide new work instructions until the campaign is reactivated.

Owners should understand that while the campaign is paused, no service action can be taken to address the front diffuser attachment point seal. Mercedes-Benz is NOT notifying consumers directly about this temporary deactivation, so it is crucial for owners to proactively stay informed.

Warranty and Dealer Claims

For repair orders (ROs) with open dates on or prior to July 20, 2023, Mercedes-Benz will accept claims. If any errors occur during this process, dealers are instructed to open a Warranty OneTrac case for issue resolution. This ensures that any work performed before the deactivation, or claims related to it, can still be processed. However, new repairs cannot be initiated until the campaign is reactivated.

Next Steps for Owners

If you own a 2021 Mercedes-Benz AMG GT Black Series and have concerns about the front diffuser, it is recommended to direct all inquiries to the Mercedes-Benz Customer Assistance Center. You can reach them at 1-800-FOR-MERCEDES (1-800-367-6372).

While the campaign is deactivated, no repair can be scheduled. However, contacting customer service can provide you with the most up-to-date information regarding the expected reactivation timeline and any future steps once the revised work instructions are issued. This ensures you are prepared when the AMG GT front diffuser campaign becomes active again.
