What Does Mercedes-Benz’s Certified Pre-Owned Warranty Cover?

Mercedes-Benz offers a certified pre-owned program for vehicles six years old or less and with fewer than 75,000 miles. Eligibility is determined by the vehicle’s initial sale’s date. Mercedes-Benz certified pre-owned vehicles come with the balance of the original four-year/50,000-mile new-car warranty, plus an additional one-year/unlimited-mileage warranty. If the new-car warranty has expired, you’ll just receive the one-year/unlimited-mileage warranty. Every Mercedes-Benz CPO vehicle must pass a 165-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Mercedes-Benz warranty page carefully.

Based on our research, Mercedes' CPO program is better than what you'll get from Lincoln or Acura, but it's not as good as the CPO benefits offered by Lexus and Volvo.
