2021 Mercedes-Benz AMG GT DMTL Warranty Extended

Mercedes-Benz USA has announced an important warranty extension for the Diagnostic Module for Tank Leakage Detection (DMTL) on several of its models, including the 2021 Mercedes-Benz AMG GT. This initiative aims to ensure proper vehicle performance and enhance customer satisfaction by addressing potential issues with the DMTL system.

Why This Matters

The Diagnostic Module for Tank Leakage Detection (DMTL) is a critical component of your vehicle's emissions system. Its primary function is to monitor the fuel tank for any leaks. Under certain circumstances, the DMTL may trigger erroneous Diagnostic Trouble Code (DTC) entries, which can lead to the illumination of the "Check Engine Malfunction Indicator Lamp ('MIL')" on your dashboard.

This warranty extension applies to certain Model Year 2018-2023 Mercedes-Benz A, C, CLA, CLS, E, G, GLA, GLB, GLC, GLE, GLS, GT, S, and SL vehicles, including the 2021 Mercedes-Benz AMG GT. The original New Vehicle Limited Warranty for the DMTL, which was 4 years or 50,000 miles, is now extended to 15 years or 150,000 miles, whichever occurs first. This extended coverage applies regardless of vehicle ownership.

Symptoms

The primary symptom of a potential DMTL issue covered by this warranty extension is the illumination of the "Check Engine Malfunction Indicator Lamp ('MIL')" on your vehicle's instrument cluster. This light indicates that the system has detected an emissions-related fault, which, in this case, could be due to erroneous DTC entries from the DMTL.

How to Get Your Vehicle Repaired

If you experience the Check Engine Light illuminating and suspect a DMTL issue, you should visit an authorized Mercedes-Benz dealership. The dealership will perform a diagnosis to confirm if your vehicle has the specific issue covered by this extended warranty. If confirmed, the repair will be performed at no cost to you.

This extended warranty specifically covers the Diagnostic Module for Tank Leakage Detection (DMTL) and its related activation of the Check Engine Malfunction Indicator Lamp. It does not apply to any other components or conditions beyond those explicitly mentioned. Standard warranty terms and exclusions regarding extra expenses, as detailed in your Service and Warranty Information booklet, still apply.

Reimbursement for Previous Repairs

If your 2021 Mercedes-Benz AMG GT or other affected Mercedes-Benz vehicle has already exceeded its original warranty period and you paid for a DMTL repair that resulted from a Check Engine Light activation, you may be eligible for reimbursement. To claim reimbursement, you will need to present specific documentation to your servicing or closest authorized Mercedes-Benz dealership. This documentation must include:

• The name and address of the person who paid for the repair.
• The Vehicle Identification Number (VIN) of the repaired vehicle.
• A description of the problem, the repair performed, the date of repair, and who performed it.
• Proof that only Mercedes-Benz replacement parts were used.
• Any Fault Code (DTCs) information related to this warranty extension.
• The total cost of the repair expense.
• Proof of payment, such as a copy of a cancelled check or credit card receipt.

Reimbursement may be limited to the amount an authorized Mercedes-Benz dealership would have charged for the repair. Repairs performed by non-Mercedes-Benz dealerships might not be reimbursed. Approved reimbursements will typically be paid by check from your authorized Mercedes-Benz dealership within 60 days.

Important Warnings

• This extended warranty does not apply to any other components or conditions beyond the ones mentioned above.
• Standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet.
