If by “worst maintenance” you mean the most expensive, complicated, or demanding to maintain, there isn’t one universally recognized #1. However, luxury European vehicles, high-performance cars, older premium vehicles, and complex SUVs often have higher maintenance and repair costs.
Brands such as Land Rover, Mercedes-Benz, BMW, Audi, and Porsche can be expensive to maintain, especially as they age. However, costs depend heavily on the specific model, engine, transmission, mileage, and maintenance history.
The better question is: Which specific vehicle is likely to cost the most to maintain over time?
What Makes a Car Expensive to Maintain?
Maintenance costs can increase when a vehicle has:
- Complex engines or turbochargers
- Sophisticated transmissions
- Expensive specialty parts
- Advanced electronics and sensors
- Complicated suspension systems
- High-performance brakes
- Difficult-to-access components
- Specialized diagnostic requirements
- Limited replacement-part availability
A vehicle doesn’t have to break down frequently to be expensive. Luxury vehicles, for example, may be reliable but still cost more for brakes, tires, fluids, electronics, and specialized service.
Which Cars Tend to Have the Worst Maintenance Costs?
There isn’t one ranking that applies to every model year, but these categories commonly have higher ownership costs:
| Vehicle Type | Typical Concern |
| Luxury European vehicles | Expensive parts and specialized labor |
| High-performance cars | Premium brakes, tires, and components |
| Older luxury vehicles | Aging electronics and complex systems |
| Complex SUVs | Air suspension and drivetrain repairs |
| Turbocharged vehicles | Additional components and heat management |
| Hybrid/EV vehicles | Specialized systems |
| Rare vehicles | Limited parts availability |
It’s also important to distinguish maintenance from repairs.
Maintenance vs. Repairs
Routine maintenance keeps a vehicle operating properly. It includes oil changes, brake inspections, fluid services, filter replacement, tire rotations, battery testing, spark plug replacement, and scheduled inspections.
Repairs fix components that have failed or become damaged. Examples include alternator, transmission, suspension, AC compressor, engine, and electrical repairs.
A vehicle can have reasonable routine maintenance costs but still require expensive repairs.
Why Luxury Cars Can Cost More to Maintain
Luxury vehicles often use advanced technology and expensive components, including:
- Air suspension and adaptive dampers
- Turbocharged engines
- Advanced cooling systems
- Performance braking systems
- Multiple electronic control modules
- Driver-assistance technology
These systems improve comfort and performance, but replacing them can cost considerably more than repairing a basic economy vehicle.
Land Rover and Range Rover
Some Land Rover and Range Rover models are associated with higher ownership costs. Potential expenses can involve air suspension, cooling systems, electrical components, turbocharged engines, transmissions, sensors, and control modules.
Reliability varies substantially by model and year, so a well-maintained vehicle can perform much better than a neglected one.
Mercedes-Benz
Mercedes-Benz vehicles can become expensive to maintain as they age. Depending on the model, owners may face higher costs for engines, transmissions, suspension, electronic modules, climate-control systems, and driver-assistance technology.
Specialized diagnostic equipment may also be required for certain repairs. This doesn’t mean every Mercedes-Benz is unreliable; it means owners should budget for potentially higher ownership costs.
BMW
BMW vehicles offer performance and technology but some models can become expensive as mileage increases. Common expenses can involve cooling systems, oil leaks, suspension components, turbochargers, electrical systems, and engine components.
The specific model and engine are extremely important when evaluating long-term costs.
Audi
Audi vehicles can also have higher maintenance costs because of their engineering and technology. Depending on the model, expensive repairs may involve turbocharged engines, Quattro all-wheel drive, electronics, suspension, cooling systems, and transmission components.
Parts and labor can cost more than those for many mainstream vehicles.
Porsche
Porsche vehicles can also cost more to maintain because of their performance-focused components. Owners may pay more for premium tires, performance brakes, specialized fluids, and complex service procedures.
A Porsche isn’t necessarily unreliable. Its higher maintenance costs often reflect its performance and engineering.
Which Cars Have the Cheapest Maintenance?
If minimizing maintenance expenses is your priority, simpler mainstream vehicles generally have an advantage. Brands such as Toyota, Honda, Mazda, Hyundai, and Kia offer models that can be relatively straightforward and affordable to maintain.
However, brand alone isn’t enough. The specific model, engine, transmission, year, and maintenance history can make a major difference.
What Is the Most Expensive Maintenance on a Car?
Some services naturally cost more because they require significant labor or multiple components.
Timing Belt Service
Depending on the vehicle, timing belt service may include the belt, tensioners, pulleys, water pump, seals, and coolant. This can become a major scheduled maintenance expense.
Brake Service
Luxury and performance vehicles may use expensive brake components, increasing replacement costs.
Transmission Service
Some vehicles require specialized fluids, equipment, or procedures that increase service costs.
Spark Plug Service
Certain engines have difficult-to-access spark plugs, increasing labor time.
Cooling-System Service
Turbocharged and high-performance engines may have more complicated cooling systems and additional components.
How Much Does Car Maintenance Cost?
Costs vary by vehicle, location, and repair shop. As a general budgeting guide:
| Service | Approximate Cost |
| Oil change | $40–$150+ |
| Brake service | $300–$1,000+ |
| Battery replacement | $100–$400+ |
| Tire replacement | $500–$1,500+ |
| Spark plugs | $150–$600+ |
| Timing belt service | $600–$2,000+ |
| Major scheduled service | $500–$2,000+ |
Luxury and performance vehicles can exceed these ranges substantially.
What Car Has the Worst Maintenance After 100,000 Miles?
After 100,000 miles, vehicles may need more age- and mileage-related repairs. Potential concerns include suspension components, cooling systems, engine seals, timing components, transmissions, motor mounts, alternators, starters, AC components, sensors, and batteries.
However, a well-maintained 100,000-mile vehicle can be a better purchase than a poorly maintained 70,000-mile vehicle.
Maintenance History Matters
When buying a used vehicle, don’t judge it by mileage alone. Look for evidence of:
- Regular oil changes
- Scheduled maintenance
- Brake and tire service
- Cooling-system maintenance
- Transmission service when applicable
- Major repairs and replacement parts
A documented maintenance history provides valuable information about how the vehicle was treated.
How to Reduce Car Maintenance Costs
1. Follow the Maintenance Schedule
Complete manufacturer-recommended maintenance instead of waiting for something to fail.
2. Fix Small Problems Early
A small leak, warning light, or unusual noise can become a much larger repair if ignored.
3. Use Quality Parts
The cheapest replacement part isn’t always the best long-term value.
4. Choose a Good Repair Shop
An experienced technician can identify problems and help prioritize necessary repairs.
5. Keep Service Records
Records make it easier to track maintenance and can help support the vehicle’s resale value.
What Should You Check Before Buying a Used Car?
If you’re considering a vehicle known for expensive maintenance, get a pre-purchase inspection. A technician should check the engine, transmission, cooling system, brakes, suspension, steering, tires, electrical systems, fluid leaks, undercarriage, and warning lights.
A professional inspection can uncover problems that aren’t obvious during a test drive.
Is an Expensive-to-Maintain Car Worth It?
It can be. Buyers may willingly accept higher maintenance costs for luxury, performance, comfort, towing capability, off-road ability, technology, or driving experience.
Before buying, consider the complete cost of ownership, including:
- Purchase price
- Financing
- Insurance
- Fuel
- Maintenance
- Repairs
- Tires
- Depreciation
The important question isn’t just “How much does the car cost?” It’s “How much will this car cost me to own?”
