What You Need to Know About Mercedes’ Warranty

Here’s a detailed review of Mercedes factory and extended warranties.

Your new Mercedes might be nice, but did you know that it only comes with a four-year, 50,000-mile warranty that covers the powertrain, corrosion preformation, and even includes roadside assistance. It’s a good thing, too, when you consider that the Mercedes parts catalog is ripe with parts that don’t fall on the cheap side. If the warranty booklet isn’t exactly written in your language (don’t feel bad, there’s a lot of fine print for a reason) that’s okay because everything you need to know about your Mercedes warranty is right here. Let’s take a closer look at Mercedes’s factory and extended warranty plans.

Mercedes Warranty Coverage

Mercedes sticks to the German convention and offers a pretty standard 4-years/50,000 miles factory warranty throughout its model range. Mercedes offers a fairly comprehensive warranty that includes a powertrain warranty, corrosion perforation warranty, and roadside assistance plan in that 4-year warranty period.

In the case of PHEV and EV models, however, there are a few addendums in regard to the electric powertrain. The high-voltage battery in all Mercedes PHEVs is covered by a separate limited warranty for 6 years or62,000 miles. In California, Connecticut, Massachusetts, Maryland, Maine, New Jersey, New York, Rhode Island, and Vermont, the battery for plug-in hybrid vehicles extends to 10 years/150,000 miles.

Furthermore, In certain states like California, certain parts of the emission control system are covered for 8 years/80,000 miles due to the stringent emission regulating policies. This includes things like fuel injectors, intake manifolds, certain hoses and electronics, and other parts. Mercedes covers tires against defects in material or workmanship for 12 months/12,000 miles. Within that period, a Mercedes dealer will replace a tire if it becomes “unserviceable” as long as at least 1.6 millimeters of tread depth remains. This is actually something that sets Mercedes apart from most luxury automakers who do not cover tire defects and damage. Here’s a list of coverage options Mercedes offers with new vehicles:

Mercedes Warranty Years of Coverage
Basic Warranty (Bumper-to-Bumper and Powertrain) 4 years/50,000 miles
Plug-In Hybrid Electric High Voltage Battery 6 years/62,000 miles
Emission Performance/Control Varies
Vehicle Service Parts and Accessories Limited Warranty 2 years/unlimited miles

What’s Not Covered By Mercedes Factory Warranty?

As is the case with most limited warranties, Mercedes also has a list of exclusions. This includes the following:

  • Wear-and-tear items, including brake pads and wiper blades
  • Wheel alignment and balancing
  • Glass
  • Batteries for any remote controls, including the keyless entry system
  • Damage due to lack of maintenance
  • Damage by use of unauthorized replacement parts
  • Water and Flood damage

Apart from these, Mercedes doesn’t cover damage to paint, trim, upholstery, or the convertible top caused by “airborne fallout,” which could include chemicals, tree sap, and road salt. This is actually a strange policy for Mercedes as most car manufacturers cover paint damage for up to three years. Apart from these, Mercedes is clear about not offering lodging charges or other travel reimbursements which can easily be found in the case of third-party warranty providers.

Mercedes CPO Warranty

Mercedes practically pioneered the Certified Pre-Owned (CPO) program back in the 90s to offer a one-stop destination for buyers looking for used Mercedes without any of the compromises that come with a used vehicle. This is why Mercedes’s CPO plan continues to be one of the most rigorous in the industry when it comes to selecting vehicles.

For starters, any Mercedes that is certified via the CPO program is less than six years old and has less than 75,000 miles on the odometer. Each vehicle goes through a 165-point inspection which is less than BMW CPOs 200-point inspection. Vehicles with identifiable structural damage or a problems shown in a CARFAX Vehicle History Report are not approved for the CPO program.

As is the case with most other CPOs offered by luxury automakers, you get the remainder of the 4-year/50,000 mile New Vehicle Limited Warranty (if any) plus another 12 months of coverage along with unlimited miles of comprehensive coverage. According to Mercedes, its CPO coverage extends to the powertrain, steering, suspension, brakes, electrical and climate control systems, and more. Mercedes goes the extra mile by offering you the choice to extend the duration of this warranty by up to two years.

Mercedes Reliability

Back in the 50s through to the 80s, Mercedes was the final word in reliability and quality. They were known for making bulletproof vehicles but all this changed by the dawn of the 21st century when cars got infused with technology and Mercedes started to lose its edge. According to J.D Power Dependability Study conducted in 2021 which surveys three-year-old vehicles, Mercedes was found to have 122 problems per 100 cars. That’s just below the industry standard of 121 but this means Mercedes does rank significantly lower than some of its competitors like Lexus at just 81 and Porsche at 86.

Mercedes-Benz Repair Costs

All-new Mercedes vehicles are complex technological marvels on four wheels and all that technological excellence comes at a cost, high cost of maintenance and repairs to be precise. Here’s a list of repair costs by Repair Pal for different Mercedes vehicles from 2016:

  • 2016 Mercedes-Benz GLE350 sport-utility cylinder head gasket:$1,918–$3,180.

Our Recommended Third-Party Extended Warranties

Mercedes offers a fairly thorough 7-years/100,000 miles warranty, which is on par with other German automakers and should cater to most. But what if you need coverage that lasts longer? Third-party warranty providers offer a wider range of coverage options and they even offer better protection for higher-mileage cars, usually at a lower cost.

Most third-party providers will offer better coverage, not just for your new Mercedes, but also for CPOs. Endurance for example offers three distinct plans that can cover your vehicle for up to 8 years/200,000+ miles. Apart from a significantly better coverage duration, Endurance and other third-party providers offer additional perks that make life easier as an owner.

For instance, a factory Mercedes warranty will limit your regular maintenance to an authorized Mercedes dealer under warranty, whereas with an aftermarket warranty, you can take it to any authorized dealership that suits your convenience which is huge in terms of convenience considering only 375 of the 160,000+ auto repair facilities in the country are Mercedes dealers. As a result, we do recommend taking a look at Endurance Extended Warranty and other extended warranty providers before buying extended coverage for your Mercedes.
