Remember that all new Mercedes vehicles come with the Mercedes-Benz New Vehicle Limited Warranty, which covers your car for 4 years or 50,000 miles, whichever comes first. The extended limited warranty for your Mercedes-Benz covers the same components as the factory warranty, but extends coverage for an additional one, two, or three years. The Mercedes extended warranty runs from about $2,000 to $8,000.
Warranties only cover defective components of your car. That means if a component in your car starts malfunctioning because, say, you forgot to change your oil or you got into a car crash, those repairs will not be covered by your warranty.
