| Roadside Assistance | Coverage for breakdowns, flat tires, and other emergencies. | Often included with the vehicle purchase or available as a separate subscription. |
| Insurance Costs | Insurance premiums can vary depending on the driver's record, location, and coverage level. | Check with your insurance provider for specific rates. |
| Depreciation | The value of the Mirai will decrease over time, like any vehicle. | Depreciation rates can vary depending on market conditions and mileage. |
Detailed Explanations
Scheduled Maintenance: Scheduled maintenance is crucial for any vehicle, but especially important for the Mirai due to its complex systems. These services include inspections of various components, fluid checks, and filter replacements. Toyota offers complimentary scheduled maintenance for the first 3 years or 36,000 miles, which significantly reduces initial ownership costs. After the warranty period, expect to pay between $100 and $300 per visit, depending on the services required.
Fuel Cell Stack Maintenance: The fuel cell stack is the core component of the Mirai, responsible for generating electricity from hydrogen. It's designed for durability, but eventual maintenance or replacement may be necessary. The replacement cost for a fuel cell stack can be substantial, potentially exceeding $20,000. Fortunately, Toyota provides an 8-year/100,000-mile warranty on the fuel cell stack, offering peace of mind to owners. Proper maintenance and adherence to recommended service intervals can help prolong the life of the fuel cell stack.
Hydrogen Fuel Costs: The cost of hydrogen fuel is a significant factor in the overall cost of ownership. Hydrogen prices vary considerably depending on location, availability, and government incentives. Currently, the price per kilogram ranges from $12 to $36. The Mirai typically achieves around 60-70 miles per kilogram of hydrogen. Therefore, fuel costs can fluctuate significantly depending on driving habits and the availability of affordable hydrogen fuel.
High-Voltage Battery Maintenance: The Mirai utilizes a high-voltage battery to store energy and provide additional power. While the battery is designed for longevity, it requires periodic checks and may eventually need replacement. Battery replacement costs can range from $3,000 to $8,000. Toyota's warranty typically covers battery degradation within a specified timeframe or mileage.
Coolant System Maintenance: The Mirai employs a sophisticated cooling system to regulate the temperature of the fuel cell stack and other critical components. Maintaining the coolant system is essential for preventing overheating and ensuring optimal performance. Coolant flushes are typically recommended every 50,000-75,000 miles and can cost between $150 and $300.
Air Filter Replacement (Fuel Cell): The air intake filter protects the fuel cell from contaminants, such as dust and debris. Regular replacement of the air filter is crucial for maintaining fuel cell performance and longevity. The replacement interval is typically every 15,000-30,000 miles, and the cost ranges from $30 to $75.
Brake System Maintenance: The Mirai uses regenerative braking, which captures energy during deceleration and reduces wear and tear on the brake pads and rotors. As a result, brake pad replacement may be less frequent compared to traditional gasoline vehicles. However, brake system maintenance is still necessary. The cost of brake pad replacement can vary depending on the extent of the work, typically ranging from $150 to $400 per axle.
Tire Maintenance: Proper tire maintenance is essential for safe and efficient driving. This includes regular tire rotations, balancing, and replacements. Tire costs depend on the chosen brand and model. Rotations and balancing typically cost between $50 and $100.
General Wear and Tear: Like any vehicle, the Mirai will require replacement of items like windshield wipers, light bulbs, and other consumable parts. The cost of general wear and tear can vary depending on usage and driving conditions. Budgeting between $100 and $300 per year is a reasonable estimate.
Software Updates: The Mirai relies on sophisticated software to manage its systems. Updates are necessary to maintain performance, security, and compatibility with evolving technologies. Software updates are typically free and performed at the dealership during scheduled maintenance.
Hydrogen Storage Tank Inspection: The Mirai's hydrogen storage tanks are designed for safety and durability. However, periodic inspections are necessary to ensure their integrity. These inspections are typically included in scheduled maintenance. Any necessary repairs or replacements are generally covered under warranty.
