Mercedes-Benz Service A and Service B Intervals

Service A is first due at approximately 10,000 miles or one year, whichever comes first. After that it repeats roughly every 20,000 miles or two years. Service B follows at approximately 20,000 miles, or one year after your previous service. It then repeats on the same 20,000-mile or two-year cycle. In practice, the two alternate about every 10,000 miles or once a year, per Mercedes-Benz USA’s published service intervals.

Your vehicle’s ASSYST PLUS maintenance computer tracks this for you. It does not simply count down to a fixed mileage. Your instrument cluster shows the service type and a countdown as the interval nears.

Warranty Service and Extended Coverage

Every new Mercedes-Benz is covered by a 4-year/50,000-mile New Vehicle Limited Warranty, per the 2026 Mercedes-Benz warranty booklet. We handle warranty repairs here, using factory-trained technicians and genuine Mercedes-Benz parts. The Mercedes-Benz Extended Limited Warranty continues that coverage. Terms run one, two, or three years, up to 75,000 or 100,000 total miles. It covers powertrain components, suspension, steering, electrical systems, climate control, and 4MATIC components. The plan is honored at authorized Mercedes-Benz dealerships nationwide and transfers to a new owner in a private sale. Separately, Mercedes-Benz Roadside Assistance is available 24 hours a day. Mercedes-Benz USA notes that roadside is separate from your vehicle’s warranties.

Common Questions About Mercedes-Benz Service

Can an independent mechanic perform routine maintenance without voiding my factory warranty?

Yes. Under the federal Magnuson-Moss Warranty Act, a manufacturer or dealer cannot void your warranty or deny a claim simply because someone other than the dealer performed routine maintenance. Mercedes-Benz USA’s own warranty booklet states that warranty obligations are not dependent on the use of any particular brand of replacement parts. Keep detailed, dated service records documenting all completed work. Factory recall campaigns, software updates, and official warranty repairs must still be completed at an authorized Mercedes-Benz service center by factory-trained technicians.

How does the ASSYST PLUS system calculate when service is due?

ASSYST PLUS monitors vehicle mileage, elapsed time, driving style, engine load, operating temperatures, and oil condition rather than relying on a fixed distance counter. Cold starts, frequent short trips, and high ambient temperatures can cause the system to adjust its service notifications, so the interval reflects how the vehicle is actually driven. The instrument cluster displays the service type and a countdown as the interval approaches.

What qualifies a vehicle owner to receive a complimentary loan car during service?

Complimentary loan cars are offered to clients scheduled for qualifying extended maintenance, major repairs, or factory warranty work, subject to daily fleet availability. To qualify, the driver must be at least 21 years of age and present a valid driver’s license, a valid insurance card, and a credit card at pickup.

What maintenance is available for all-electric Mercedes-Benz models?

Mercedes-Benz offers a two-year service coverage package available for purchase with all-electric models, performed by trained technicians using genuine Mercedes-Benz parts. The package includes a dust filter change, an activated charcoal filter change, a brake fluid change, wiper blade replacement, and a multi-point inspection.

What paperwork should I bring when dropping off my vehicle for warranty service?

Bring your driver’s license, current vehicle registration, and active auto insurance card. If you are servicing a Certified Pre-Owned model, or an older vehicle maintained outside our dealership, bringing past service records helps our advisors verify maintenance continuity.
