Key points
  • Mercedes extended warranty coverage is available for up to 3 years/100,000 miles.

  • The automaker’s warranty coverage costs are higher than average.

  • Mercedes cars have low reliability scores and high repair costs, making an extended warranty a smart investment.

As a luxury brand, Mercedes-Benz offers the appeal of quality construction, high-end performance and leading-edge technology. However, these vehicles aren’t ranked highly for dependability throughout the industry and, as imported vehicles, they typically come with hefty repair costs.

Fortunately, you can protect your luxury car investment by maintaining your vehicle’s condition and its coverage. Mercedes vehicles come with up to four years or 50,000 miles of new vehicle basic warranty coverage. If you purchase an extended warranty plan before this coverage expires, you can brace your budget for potential repair needs for up to three more years.

Below, we cover everything you need to know about Mercedes extended warranty coverage and how it compares with the best extended car warranty companies.

What does the Mercedes extended warranty cover?

Mercedes-Benz extended warranty coverage for new and certified pre-owned (CPO) vehicles includes parts and repairs for components in the engine, powertrain, suspension, brakes and other critical systems. Plans have customizable terms, so you can commit to as much — or as little — extra coverage as you’d like. All Mercedes extended warranty plans come with the company’s roadside assistance.

Mercedes new vehicle extended limited warranty

The Mercedes-Benz extended limited warranty is available for purchase before your car’s new vehicle limited warranty expires — and it kicks in as soon as it does. If you want coverage, compare your options before hitting four years or 50,000 miles with your new car.

Mercedes offers terms of one, two or three years with a maximum of 100,000 miles, regardless of contract length. The Mercedes extended limited warranty is considered exclusionary, meaning it covers most parts and systems outside a small list of exclusions. With this plan, you can expect coverage to include the following parts and systems:

  • Engine
  • Transmission
  • Supercharger
  • Four-wheel drive
  • Rear axles
  • Engine cooling system
  • Fuel injection
  • Steering
  • Electrical components
  • Suspension
  • Air conditioning/heating
  • Navigation
  • Radio

Mercedes extended warranty benefits

Both new vehicle and CPO extended limited warranties from Mercedes come with emergency roadside assistance. The program includes battery jump-start, flat tire changes, tire inflation and fuel delivery. This coverage is pretty basic — other manufacturers and providers offer additional benefits such as trip interruption or rental reimbursement coverage.

Mercedes extended warranty exclusions

Like most vehicle warranties or extended warranties, Mercedes-Benz coverage doesn’t include routine maintenance or normal wear and tear. You’ll need to keep up with oil changes, filter changes and brake pad replacements. You’ll also need to maintain your car’s wiper blades and pay for regular tire rotations.

Mercedes-Benz warranty coverage excludes aftermarket parts and alterations as well as vehicle batteries. Plans also won’t cover damage caused by the following:

  • Severe weather
  • Accidents
  • Theft or vandalism
  • Vehicle misuse
  • Improper maintenance
  • Commercial vehicle use
  • Fuel or fluid contamination
  • Corrosion

Mercedes extended warranty terms and conditions

If you use Mercedes-backed extended warranty coverage, you’ll have to take your vehicle to an authorized Mercedes-Benz dealer for repairs and services. Many drivers prefer this restriction, as it guarantees repairs will use genuine Mercedes-Benz parts.

Mercedes offers a 100% refund of your extended warranty plan cost if you cancel your coverage before your factory warranty expires. If you cancel after your extended coverage goes into effect, you may be subject to a prorated refund.

Does Mercedes offer a maintenance plan?

Yes, Mercedes owners can purchase a prepaid maintenance plan that helps with the cost of oil changes, filter replacements and other upkeep.

Here’s a list of the company’s impressive lineup of optional add-on coverages available through Mercedes dealerships:

Protection PlanCoverage Details
First Class Paintless Dent RepairThis coverage plan helps address repair costs for select dents or dings in your vehicle’s body panels. Dents and dings must be 4 inches or fewer in diameter.
First Class Wheel and Tire Protection PlusThis program covers tire repair and replacement for damage caused by road hazards. Tires must be well-maintained, and the company sets coverage maximums based on policy length.

Premier Prepaid MaintenanceThis program helps you save up to 30% on maintenance services such as oil changes, filter replacements and wiper blade replacements.

What about the Mercedes CPO extended limited warranty?

The Mercedes-Benz extended CPO limited warranty kicks in when your car’s CPO vehicle limited warranty expires. You must purchase this coverage from your dealership or directly from Mercedes before your CPO limited warranty ends, but you can choose a term limit of one or two years with no maximum mileage.

System and components covered under the Mercedes-Benz CPO extended warranty include the following:

  • Powertrain
  • Suspension
  • Brakes
  • Steering
  • Electrical
  • Climate control
  • Radios, stereos or CD players
  • Navigation systems

What is Mercedes’ factory warranty?

Mercedes vehicles come with a new vehicle limited warranty that lasts 4 years/50,000 miles. While this term limit is standard for new vehicle warranties, Mercedes powertrain coverage for new vehicles also cuts off at this limit. Many manufacturers offer longer powertrain warranty coverage.

How much does a Mercedes extended warranty cost?

Mercedes-Benz doesn’t provide pricing information for its warranty coverage on its website. However, based on what customers on Reddit are saying, you might expect to pay between $4,000 and $5,000 for up to three years of extended coverage. Plan brochures indicate that neither of the company’s extended warranty options requires you to pay a deductible for covered services.

What does the average extended warranty cost?

Customers report high costs for Mercedes-Benz extended warranties, but comprehensive repair coverage doesn’t have to break the bank. The table below shows that the average cost of bumper-to-bumper warranty coverage from third-party providers we’ve reviewed is far lower.

Extended Warranty TypeTotal Cost
Bumper-to-bumper$2,586
Midlevel$3,151
Powertrain$2,892

Compared with average extended warranty costs, Mercedes’ potential $4,000–$5,000 cost for up to three years of coverage might seem like a lot of money — especially if you’re unsure you’d need it. However, a closer look at Mercedes-Benz vehicles’ reliability and repair costs may change your mind.

Is a Mercedes extended warranty worth it?

Based on what the industry and drivers say, we think an extended vehicle service contract is a good call if you want to keep your Mercedes-Benz on the road for longer.

Are Mercedes reliable?

RepairPal ranks Mercedes-Benz reliability as average, placing it at No. 27 out of 32 vehicle brands. That’s significantly lower than brands such as Nissan, which ranks No 9.

Echoing Mercedes’ RepairPal ranking, J.D. Power placed Mercedes-Benz vehicles at No. 21 out of 29 ranked vehicle brands in its 2024 Vehicle Dependability Study.

How much are Mercedes repairs?

Even well-maintained vehicles can encounter mechanical failures. With Mercedes, you might need to brace yourself for steep repair costs. RepairPal estimates the average annual repair cost for Mercedes-Benz vehicles at $908, well above the average of $652 per year across all 32 automakers included in the ranking.

Because $908 is the average repair cost, you might pay significantly more for select individual repairs. The table below details reported repair needs for Mercedes vehicles and RepairPal’s estimates of what these repairs typically cost.

Mercedes-Benz RepairAverage Cost Estimate
R320 check engine light diagnosis and testing$114–$144
R350 air conditioning refrigerant pressure sensor replacement$254–$259
E400 timing chain tensioner replacement$653–$685
S550 steering knuckle replacement$848–$926
GL450 radiator replacement$1,189–1,273

What Mercedes owners say

Many Mercedes owners feel hesitant about extended warranty coverage. Opinions are mixed as to whether warranty coverage is worth buying directly from the manufacturer since plans cost several thousand dollars. However, some Mercedes owners recommend investing in an extended warranty for the added peace of mind and improved vehicle resale value.

Where should you buy a Mercedes extended warranty?

If you want to purchase a Mercedes-Benz extended warranty directly from the automaker, you’ll need to do so before your car’s new vehicle’s limited warranty expires. Like many manufacturers, Mercedes requires drivers to purchase extended coverage before original coverage expires to ensure there has been no lapse in vehicle upkeep and to protect the company’s bottom line.

When you speak to your Mercedes dealership, remember that the automaker isn’t your only option for dependable coverage. If you don’t like the coverage options or price point you’re quoted, compare Mercedes’ offer against a leading third-party company’s contract.

Manufacturer vs. third-party extended car warranties

One of the primary benefits of Mercedes’ plan is that it doesn’t have a deductible. This means you won’t have to pay anything out of pocket in the event of a covered repair. However, you may have the choice of a $0 deductible with other warranty companies. Remember that the lower the deductible you choose, the higher your warranty payments may be.

You’ll also have more coverage choices with third-party providers, with companies such as Endurance and CarShield offering up to six plans.

What’s next?

Mercedes’ extended warranty coverage is short-lived — up to three years for new vehicles and up to two years for CPO vehicles. The company also offers only one coverage option per vehicle class, while other manufacturers and third-party warranty providers may offer flexible coverage choices.

Mercedes-Benz vehicles aren’t exactly known for being dependable, and as imports, these vehicles can carry steep repair costs. The right extended car warranty can help shield your budget from the sudden shock of a mechanical breakdown.
