IMPORTANT EMISSION EXTENDED WARRANTY INFORMATION
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 exhaust valve system 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).
This extended warranty applies to the condition described below that may necessitate the repair or replacement of components
related to the exhaust valve assembly (e.g. exhaust valve, cylinder head).
•
The valve guide and/or seat ring may wear over time due to increased lateral forces during operation. This could potentially
cause combustion misfire for cylinder 1 through 4, resulting in an activation of the check engine Malfunction Indicator Lamp
(“MIL”).
The following models are included in this emission extended warranty

A-Class 2019 – 2022
CLA-Class 2020 – 2022
