Are you curious about potential issues with the Toyota Mirai? You’re in the right place to learn about some of the most common problems that Mirai owners have reported.

This fuel-cell vehicle may be a promising eco-friendly option, but there are still some hurdles to overcome.

In the following paragraphs, you’ll find key information on why the Toyota Mirai might not be the perfect choice for everyone.

Keep my freshly served tutorials to discover the challenges with the Mirai as well as some useful tips on how to deal with these issues.

Common Toyota Mirai Problems

Hydrogen Fuel Cell Issues

One of the main issues faced by the Toyota Mirai is related to its hydrogen fuel cell system. The fuel cell stack combines hydrogen fuel with oxygen from the air to generate electricity.

However, there have been cases of fuel cell system failure when driving down long hills with cruise control engaged followed by quick acceleration.

This could cause the car to quit due to voltage fluctuations from the fuel cell boost converter. Toyota has released a software update to address this problem.

Range and Refueling Limitations

Another concern with the Toyota Mirai is related to its driving range.

While the manufacturer advertised a range of 402 miles for the 2021 Toyota Mirai, many drivers have reported only getting an average of 230-270 miles, despite having a full hydrogen tank.

This is especially concerning for those who rely on their Mirai as their primary vehicle or travel long distances frequently.

Refueling can also be a challenge due to the limited number of hydrogen refueling stations available in certain areas, particularly outside of California.

This can lead to inconvenience for Mirai owners who need to plan their routes accordingly and may limit longer trips or extended use in areas without convenient access to hydrogen fueling stations.

Cabin Quality and Comfort

While the Toyota Mirai is designed to be a comfortable and efficient EV, it does have its drawbacks in terms of cabin quality and comfort.

The interior, though stylish, can feel tight on space, particularly for taller passengers.

Additionally, some drivers may notice a lack of power when driving the Mirai.

This may result in slower acceleration and overall sluggish performance, which can be frustrating when trying to merge onto highways or pass other vehicles on the road.

Maintenance and Reliability

As with any vehicle, maintenance and reliability are essential factors to consider when owning a Toyota Mirai.

While the Mirai is generally perceived to be a reliable vehicle, there have been minor issues that some owners have experienced.

For example, a potential risk for major repairs within the first year of ownership can be expected, much like any car on the market.

It’s crucial that you stay up-to-date with recommended maintenance procedures and address any concerns or issues early on to ensure the longevity and performance of your Mirai.

In conclusion, the Toyota Mirai is an innovative and eco-friendly vehicle that offers a unique alternative to traditional gasoline-powered cars.

However, it’s essential to be aware of the potential issues that Mirai owners may encounter, such as hydrogen fuel cell system problems, range and refueling limitations, and cabin quality and comfort concerns.

By staying informed and proactive in addressing these concerns, you can maximize the enjoyment and performance of your Toyota Mirai for years to come.

Performance and Features

Cruise Control Issues

While driving your Toyota Mirai, you might encounter some difficulties with the cruise control system.

There have been reports of the system not maintaining a steady speed or suddenly disengaging.

To help avoid this issue, ensure that your Mirai’s software is up to date, and if the problem persists, consult your local Toyota service center for assistance.

Safety Features and Camera

Your Mirai comes equipped with an array of safety features to help protect you and your passengers on the road. Some of these features include:

  • Pre-collision system
  • Lane departure alert
  • Automatic high beams
  • Road sign assist

However, there might be instances where the safety camera experiences occasional glitches or reduced visibility due to external factors such as weather conditions.

In this case, it is essential to clean the camera lens and be extra cautious while driving.

Electric Motor Performance

The Toyota Mirai is an electric vehicle powered by a fuel cell system, offering a unique driving experience. Its electric motor has several benefits, such as:

  • Smooth acceleration
  • Low noise levels
  • Reduced emissions

Although electric motor performance is usually reliable, you might experience some issues related to the power output or the fuel cell system.

If you ever face any performance problems, reach out to your Toyota service center to address the issue promptly.

Keeping your Toyota Mirai in optimal condition and being aware of these potential issues is crucial for experiencing the best performance and features this innovative vehicle has to offer.

Toyota Mirai Competitors

Toyota Prius

The Toyota Prius is one of the Mirai’s competitors, primarily due to its status as a well-established hybrid vehicle.

Unlike the Mirai, which is a fuel cell vehicle, the Prius relies on a gasoline-electric hybrid system.

This difference in powertrains means that you won’t face the same hydrogen refueling issues with the Prius as you would with the Mirai, though the Prius has some issues years.

However, the Prius doesn’t offer the same zero-emission driving experience, which could be a drawback for those looking to minimize their environmental impact.

Tesla Model 3

Tesla’s Model 3 is another competitor for the Mirai, but this time in the all-electric category.

With an electric powertrain, you’ll find refueling is easier and more widely accessible than for the Mirai, as charging stations for EVs are more widely available than hydrogen refueling stations.

Additionally, the Model 3 offers impressive performance and a longer driving range, making it an attractive option for those who prioritize driving dynamics.

However, the upfront cost for the Model 3 might be higher, which could be a consideration for some buyers as well there are Tesla’s Model 3 models with negative experience to avoid.

Hyundai Nexo

The Hyundai Nexo is a direct competitor to the Mirai in the fuel cell vehicle market. Similar to the Mirai, it offers zero-emission driving with its hydrogen fuel cell powertrain.

The Nexo provides a slightly longer driving range, which might be appealing for those who are worried about hydrogen refueling availability.

However, you’ll still face the same key problems of limited hydrogen infrastructure and higher refueling costs compared to traditional gasoline or electric vehicles.

By considering these competitors, you can weigh your options and make a more informed decision about which eco-friendly vehicle is the best fit for your needs.
