Subaru Vs. Toyota Reliability Explained With Differences: Which Is More Reliable?

Last Updated on November 14, 2021 by

Subaru and Toyota are the most popular car brands in the USA, each having numerous loyal customers. Customers love and value these brands because of their performance and reliability. Reliability is the ability of your car to get to your destination each time without breaking down.

Different methods of determining a vehicle’s reliability include how often the car will need repairs and how much these repairs cost. The mileage your car can travel with just regular maintenance and not needing any repairs is also used to measure reliability. 

Using these different methods, both Subaru and Toyota rank high in terms of reliability. If you want a vehicle that will handle all-weather terrain, is safe and durable, Subaru will work best for you. If you want to get a car that needs minimal maintenance and will get you to your destination without breaking down, Toyota will work best for you.

Servicing a Subaru will cost more, but the vehicle can last more than 300,000 miles with regular maintenance. On the other hand, servicing a Toyota will cost less, and with regular maintenance and gentle use, the vehicle can last for over 100,000miles or 10 to 15 years. This article seeks to help you understand a car’s reliability, factors affecting reliability, and how you can improve a vehicle’s reliability. Keep reading!

How Is A Car’s Reliability Determined?

 There are several methods used to determine a car’s reliability. They include:

1. Reliability index

2. The average cost of repairs

3. Cost of basic maintenance

4. Consumer Surveys 

5. After-sale benefits

6. Fuel consumption

Let’s look at each method above, describe them in detail, and see how Subaru and Toyota compare in the different reliability measures.

1. Reliability Index

The reliability index is a universal measure computed by accounting for all the times a car fails, the cost of repairs, and the average time a vehicle spends off the road due to repairs. It is comprehensive and also takes into consideration the vehicle’s mileage and average age. The lower the reliability index score, the better the vehicle, the higher the index, the worse the car.

Most cars have an average reliability index score of 100, but the standard reliability index score is 118. Cars with a reliability index higher than 118 are considered less reliable, while those scoring less than 118 are very reliable.

According to the reliability index rating, Toyota is more reliable with a 4 out of 5 and ranks 8th out of all brands. Subaru is less reliable with a 3.5 out of 5 and ranks 14th out of the 32 brands.

2. The Average Cost Of Repairs

Another popular method used to determine a vehicle’s reliability is the cost of repairs. When comparing different models, to find out which is more reliable, you consider repairing the same problem in the different cars. For example, you compare how much it would cost to repair an axle and suspension problem in a Toyota RAV4 vs. a Subaru forester. I find this method a bit biased because different models will have different complaints, and the cost of labor and spares will also play a role. However, if you are torn between buying two different cars, you can use this method to decide which will be more cost-efficient and less straining on your budget to repair.

Below Is A Table Comparing Cost Of Repair For Diferent Models Of Subaru And Toyota.

Vehicle modelsCommon complainsThe average cost of repair
Subaru Forester vs Toyota Rav 4Engine, axle, and suspensionForester :$900Rav 4: $450
Subaru legacy vs Toyota corollaEngine and gearboxLegacy:$750Corolla: $350
Subaru imprezza vs toyota Axio Brakes and axle Imprezza: $320 Axio: $280

3. Cost Of Basic Maintenance

Every vehicle comes with a manufacturer’s manual that provides guidelines on its maintenance schedule for optimal performance. The schedule includes oil changes, checking the brakes and tires, and general maintenance. You will also need to replace some components, such as filters, from time to time. 

The cost of servicing and maintaining your car will vary depending on the specific model and mileage. The average cost of maintaining a Subaru is about $800 per year, with some models costing less and others having a higher maintenance cost. Subaru Impreza is the cheapest to maintain, with costs ranging between $95- $320. The average cost of maintaining a Toyota is $450 per year, making it very economical.

Going by the cost of maintenance, Toyota is more reliable than Subaru.

Comparing How Much It Costs To Maintain Different Vehicle Models

Car model Average 5-year Maintenance cost 
Toyota Prius 2016$5,365
Toyota Corolla 2016$ 4,814
Toyota Rav4 $6,080
Toyota Camry $4,600
Subaru Forester$6,500
Subaru Impreza $6,000
Subaru WRX$3,400
Subaru Outback $ 2,500 

1. Consumer Surveys

How well a vehicle performs on consumer surveys is also a good measure of reliability. Numerous reliability surveys touch on Subaru and Toyota. Let’s look at some of them and see which brands rank better.

Consumer survey Toyota brand positionSubaru brand position 
Telegraph 101
What car survey 52
Driver power survey 106
Reliability index survey 418
Customer satisfaction 90.54%91.09%

From consumer surveys, Subaru is more reliable than Toyota; their customer satisfaction index is almost similar. These brands are all popular with loyal customers, and that’s why the surveys show excellent reliability for both brands. 

2. After-sale Benefits 

After-sale services and benefits will also determine how reliable a vehicle is. If you are getting a warranty covering the vehicle for long, you will save up on costs and feel comfortable about the car you’re getting. Another common dealer benefit is having a mechanic come to you when needed.

According to the JD Power customer service index study, Toyota has better after-sale benefits with a score of 799 compared to Subaru, which is 789.

3. Fuel Consumption 

With the current state of the economy, fuel consumption is a significant factor when determining which car you will buy. Most people consider cars with low consumption as reliable while the guzzlers are less reliable. Most Toyota models consume less fuel than Subaru, but you will need to compare the specific models you want to buy to find which consumes less.

Tips For Improving Your Cars Reliability

After buying the car you always wanted, it is essential to maintain it and improve its reliability. Here are some helpful tips for improving your vehicle’s reliability:

1. Replace the air filter with a washable and more efficient filter.

2. Add an oil catch that will capture and filter any recirculated oil or junk that gets to the combustion chamber.

3. Use a pressurized radiator cap and an overflow tank to catch excess coolant.
