Which cars are the most and least reliable?

This article has been updated from a previous version.

Buying a new car can be costly. When forking over that type of cash, most drivers expect to be happy with their wheels for years to come. However, not all new cars are trouble-free. Some vehicles have transmission troubles, make weird noises, squeak, leak, or require more than their fair share of maintenance.

With so many automakers and models to choose from, you can never be sure which dealership is worth visiting.  

We’ve identified the vehicles that are more likely to run smoothly from day one, as well as those that may give you a headache further down the road.  

Some factors to consider when choosing your ideal car

A car’s reliability and how long it will last you is dependent on many things. Going about that process can feel overwhelming. But it doesn’t have to be. Here are some things you should consider when shopping for your car (whether it’s new, bought from a used car dealership or from a private seller:

Determine your needs: Before diving into the car-buying process, assess your lifestyle, family size, commuting requirements, and preferred vehicle type. Are you looking for a compact city car, a minivan for a growing family, or a powerful pickup truck for business? Identifying your specific needs will help narrow down your options.

Set a budget: Establish a realistic budget that covers both the purchase price and ongoing expenses (fuel, insurance, maintenance, repairs). Remember that the cost of ownership extends beyond the initial price tag.

Research vehicle models: Explore various car models by reading consumer reviews, considering fuel efficiency, safety features, performance, and reliability. Online platforms and automotive magazines provide valuable insights.

Explore available features: Modern cars offer a range of features. Prioritize those important to you—whether it’s all-wheel drive for extreme weather or adaptive cruise control for long road trips.

Consider fuel efficiency: Fuel costs impact overall ownership expenses. Evaluate the fuel efficiency of the vehicle, especially if you have a daily commute or frequent road trips.

Evaluate safety features: Prioritize safety. Look for features like ABS, stability control, blind-spot monitoring, lane departure warning, and multiple airbags.

Test drive: Take the car for a test drive to experience its handling, acceleration, braking, comfort, and noise levels. Compare different models to find the best fit.

Seek vehicle history and condition: If considering a used car, obtain a complete vehicle history report. Additionally, have a trusted mechanic inspect the vehicle to ensure its mechanical condition is sound.

Remember, choosing the right car involves thoughtful consideration and research. Happy car hunting!

How many years/km should you expect to have a car run smoothly for?  

Proper car maintenance plays a crucial role. By adhering to the manufacturer’s service schedule, a reliable modern vehicle should easily reach 200,000 miles or beyond.

Certain cars’ make and models are known for their longevity, such as the Toyota 4Runner or Lexus GX.

How much should you reasonably budget for upkeep?

While the general estimate is around $2,000 per year, the actual expenses can vary based on factors like your car model, driving habits, and local prices.

Some cars cost less than others to upkeep. For example, for a Toyota 4Runner, you can expect to spend approximately $514 per year on maintenance.

Here are some additional considerations:

Scheduled maintenance: Follow the manufacturer’s recommended service intervals. Toyota provides a maintenance schedule based on your vehicle’s age or mileage. Regular check-ups help catch issues early and prevent costly repairs. This includes oil changes, tire rotations, brake inspections, and fluid replacements.

Quality parts: Use original equipment manufacturer parts (OEM) for repairs. They ensure reliability and performance, preserving your car’s value.

Accidents and unexpected repairs: Be prepared for unforeseen events. Having an emergency fund for car repairs is wise.

Most and least reliable car brands in 2024 

Consumer Reports (CR) evaluates the reliability of cars based on four key factors: road test performance, predicted reliability, owner satisfaction, and safety ratings.  

The road-test program includes over 50 tests on approximately 50 new cars and trucks each year, covering aspects like acceleration, braking, handling, and fuel economy.  

Reliability predictions come from detailed survey member feedback on 20 key trouble areas. These areas range from minor nuisances like squeaky brakes and broken interior trim to more significant issues such as expensive out-of-warranty engine, transmission, EV battery, and EV charging problems.

Owner satisfaction reflects whether a car met an owner’s expectations, considering driving experience, comfort, and value.  

Lastly, safety ratings incorporate crash-test data from organizations like the Insurance Institute for Highway Safety (IIHS) and the National Highway Traffic Safety Administration (NHTSA), along with advanced safety systems and fail-safes.

Based on this analysis, here’s the most and least reliable models in descending order.

Does a car's reliability impact insurance premiums?

Understanding a vehicle’s reliability is essential when making a purchasing decision. Equally important is knowing the cost of insuring that vehicle.

Insurance companies use rate groups to determine premium pricing. These groups consider factors such as accident history, safety ratings, and the likelihood of theft.

The cost of your insurance isn’t solely determined by your car’s make and model either. Additional factors like your age, driving history, location, and even the other drivers in your household play a role. To find the best value (and coverage) for your hard-earned dollar, explore your options and compare policies.

While insurers don’t directly consider reliability rankings, choosing a dependable car can save you future headaches and costly repairs. Not only is car insurance mandatory in Canada, but choosing the right policy is crucial. It provides peace of mind and minimizes out-of-pocket expenses in case of an unfortunate collision.
