Mercedes Maintenance: Cost, Plans and Service Schedule

Are Mercedes expensive to maintain?

At $1,241 per year, the cost to repair and maintain a Mercedes-Benz is on the higher end of the spectrum, according to RepairPal data adjusted for inflation. Compare that to the $891-per-year average for all brands.

Key factors influencing maintenance costs

What's the reason behind the high costs? Several factors contribute to Mercedes’ maintenance cost differences compared with nonluxury vehicles.

• Specialized parts and materials: Mercedes vehicles use premium components engineered specifically for performance and longevity. Genuine Mercedes parts cost more than aftermarket alternatives due to stringent quality standards and proprietary designs.
• Synthetic oil requirements: The brand requires synthetic oil formulations that exceed standard specifications, increasing routine maintenance expenses compared to conventional oil changes.
• Advanced diagnostic equipment: Modern Mercedes models incorporate sophisticated electronics and computer systems that require specialized diagnostic tools. Independent shops must invest in Mercedes-specific scan tools and software to properly service these vehicles.
• Certified technician training: Mercedes technicians undergo extensive factory training to work on complex systems like AIRMATIC suspension, COMAND infotainment and advanced driver assistance features. This specialized service expertise commands higher labor rates than general automotive repair.

It's worth noting that among luxury brands, Mercedes is actually one of the more affordable cars to keep on the road despite these higher maintenance costs.

How Mercedes compares with other automakers

While Mercedes sits about $350 above the industry average for maintenance and repair costs, according to RepairPal, other luxury brands, like BMW ($1,323) and Audi ($1,349), have average expenses even higher than Mercedes-Benz.

These statistics are helpful for comparing automakers’ lineups, but they’re not entirely accurate if you want to predict ownership costs for a given vehicle.

Mercedes maintenance and repair costs by model

For example, annual repair and maintenance costs vary considerably depending on the model you drive. Take a look at how much annual costs can vary between three popular Mercedes models in the table below to see what we mean.

It’s worth pointing out that these statistics also combine repair and maintenance costs, even though these are distinct services that require you to budget in different ways.

With that in mind, let’s break down how these costs differ for Mercedes-Benzes so you can accurately anticipate your expenses.

Mercedes maintenance cost and schedule

Mercedes-Benz splits its maintenance schedule into two cadences, with all recommended maintenance services split between what it calls the “Service A” schedule and the “Service B” schedule.

Basically, to keep your Mercedes in good shape, you need to alternate between a Service A appointment and a Service B appointment every 12 months or 10,000 miles.

Here’s a list of what’s recommended for each service.

However, you should be aware that this schedule may not be appropriate for every Mercedes-Benz. We recommend checking your owner’s manual or speaking with a local Mercedes-Benz technician if you aren’t sure what maintenance schedule to follow for your vehicle.

Maintenance costs are easier to estimate because you know when they’ll be needed. You just have to find a mechanic near you, check what they charge and map that out over your vehicle’s recommended maintenance schedule.

Maintenance schedule for severe driving conditions

Mercedes-Benz typically recommends a more frequent maintenance schedule for vehicles subjected to severe operating conditions, which include towing, frequent short trips (typically under 5 miles), stop-and-go traffic, extreme temperatures and driving in dusty, sandy or hilly terrain.

These conditions may accelerate the wear and tear on the vehicle's components, which can necessitate more frequent maintenance and sooner replacement of things like interior filters, spark plugs, coolant, engine air filters and more. Check your vehicle's owners manual or consult with your dealership’s service department for specifics.

Here are some price estimates we collected for a 2019 Mercedes-Benz GLC 300 in Austin, Texas.

Mercedes repair costs

Repair costs are harder to predict because they’re not needed on a predetermined schedule. However, you can get an idea of what to expect by looking at others’ experiences. You can look up common issues for your vehicle online and use a repair cost estimator, like RepairPal, to see what they may cost to fix.

Common Mercedes repairs and costs

Beyond major component failures, Mercedes owners encounter several routine and unexpected repairs throughout their vehicle's lifespan. These include:

• Battery replacement: Needed every four to six years. Mercedes vehicles use advanced batteries with specific power requirements, making them more expensive than standard automotive batteries.
• Spark plug replacement: Required for most models every 60,000 to 100,000 miles, depending on engine configuration. V8 and V12 engines require more plugs and additional labor, increasing replacement costs.
• Suspension components: Control arms, ball joints and air suspension parts represent frequent repair needs. Air suspension systems can be particularly expensive if compressors or air springs fail. Suspension issues typically emerge around 80,000 to 100,000 miles.
• Electrical system problems: Failed window regulators, malfunctioning seat motors and faulty sensors are common repairs. Mercedes vehicles incorporate complex electrical systems that may develop issues as the vehicle ages, particularly after 100,000 miles.
• Brake components: Beyond routine pad and rotor service, calipers and brake lines require periodic replacement. These repairs become necessary every 80,000 to 120,000 miles, depending on driving conditions.

Author’s note: From a professional technician’s standpoint, the problem with Mercedes-Benz vehicles is the same as with many other luxury brands. Not only are the parts expensive, but the labor is also more costly than normal. In some cases, repairs even require the help of a specially trained Mercedes-Benz mechanic.

If your vehicle is still in its factory warranty period, you shouldn’t need to pay anything for covered repairs. However, Mercedes-Benz’s new vehicle warranty varies based on the model you choose.

For example, a new 2023 EQB comes with a 4-year/50,000 miles bumper-to-bumper warranty and a 4-year/50,000 miles powertrain warranty. In comparison, the new 2023 Sprinter comes with a 3-year/36,000 miles bumper-to-bumper warranty and a 5-year/100,000 miles powertrain warranty. To find your warranty coverage, look in the owner’s manual or call your local dealership.

Example: 2019 Mercedes GLC 300 repair costs

Here are a few common issues you could face with a Mercedes-Benz GLC 300 and the approximate costs of fixing them, including parts and labor.

You should also at least be aware of the potential for catastrophic problems that cost considerably more to fix. These repairs aren’t as common, but they do happen.

Here are some other examples of real-world costs for specific Mercedes models:

Bulus, a ConsumerAffairs reviewer from Delaware, told us, “My MB S550 with 76,000 miles developed a ‘Check Engine’ warning light. My local MB Dealership is quoting more than $11,000 to fix the problem.”

George, a ConsumerAffairs reviewer from California, also reported major problems, writing: “Leased a brand-new 2020 AMG GTC Roadster 2/2021. On the drive home I got the first error message and noticed a busted subwoofer. After that, engine lights. Then the engine lights again. Then four simultaneous error messages. Multiple knocking sounds. Overall, the $189,000 car has been in the shop with 10 different issues for about 70 days.”

Mercedes prepaid maintenance plans

Unlike some other automakers, Mercedes-Benz doesn’t offer a nationwide free maintenance plan on new vehicles, and eventually, your factory warranty will end. At that point, you’re potentially on the hook for repair and maintenance costs.

Two popular options for saving money on maintenance expenses are prepaid maintenance plans and extended warranties, and Mercedes-Benz actually offers both.

Official Mercedes-Benz prepaid maintenance

Mercedes-Benz's line of prepaid maintenance plans covers routine maintenance for one year or 10,000 miles, whichever comes first. These plans can save you up to 30% off upcoming service appointments compared to paying for each visit separately.

Prepaid maintenance plans cover scheduled services like oil changes, filter replacements and multipoint inspections included in Mercedes-Benz's recommended maintenance schedule. You purchase the plan upfront, then bring your vehicle to an authorized dealership for covered services without additional payment.

The plans are available for purchase at the time of vehicle sale or anytime during your ownership. They're particularly valuable if you plan to keep your Mercedes for several years and want predictable maintenance costs. You can sign up through your local Mercedes-Benz dealership, which can provide specific pricing based on your model and anticipated service needs.

Extended warranties and third-party options

Extended warranties pay to fix breakdowns that result from wear and tear. Given the potentially high cost of Mercedes repairs, you may want to seriously consider extended warranty protection if you don't have several thousand dollars at your disposal. Extended warranties differ from prepaid maintenance plans — they cover unexpected repairs rather than routine service.

Mercedes-Benz's Extended Limited Warranties are available to buy before your factory New Vehicle Limited Warranty expires, and terms range from 1 year/75,000 miles to 3 years/100,000 miles. These official Mercedes plans provide comprehensive coverage using genuine parts and authorized service centers.

However, Mercedes-Benz isn't your only option for an extended warranty. Third-party extended warranty companies can often offer similar coverage at lower rates. The key to finding the right deal is to get quotes from multiple warranty providers and compare their offerings. Third-party plans may have lower monthly payments but could include service call fees, deductibles or restrictions on which repair shops you can use.
