Used Car Reliability Ratings

When you're buying a used car, reliability, quality and dependability are a critically important factor to evaluate. After all, you want to avoid the expense, hassle and lost time of a car sitting in a repair shop all too often.

The problem is that real hard and objective data can be difficult to come by. This isn't information the car manufacturers readily share in a comprehensive way. Perhaps they're a little "sensitive" about it.

Instead, it's third parties that compile various data points and often come up with conflicting results. So, I've taken a different approach for more recent used cars, using Artificial Intelligence (AI).

And this is then followed by previous ratings for even "older" used vehicles for those looking for vehicles in those time frames. Indeed, used car reliability and dependability varies over time.

Artificial Intelligence (AI) Reliability Ratings

I asked ChatGPT, an artificial intelligence app, to rank the car makers overall for their 3- to 5-year-old vehicle reliability. (For individual models, I'd recommend RepairPal's great site.) ChatGPT's last knowledge cutoff date was in September, 2021, so this works out fairly well for the current time frame.

The following are the results, along with ChatGTP's brief description of each brand:

1. Toyota: Toyota consistently ranks high for reliability, offering dependable vehicles known for longevity and low maintenance costs.

2. Lexus: Lexus, Toyota's luxury division, combines reliability with luxury and quality, making it a top choice for dependable upscale vehicles.

Reliability For Top Models In The Early 2010's

2012 Ford Fusion

For vehicles a little older, here's an excellent study by J.D. Power in the earlier 2010's that is no longer online but was reported here at the time. It was based on consumer feedback after three years of ownership and dealt with specific models as opposed to an overall automaker. I think this can be very useful for car buyers looking for older vehicles who want to identify the top models for reliability by segment. Here are the results:

Most Reliable Automakers In The 2000's

For car buyers looking for models in the 2000's, this was a very interesting and hands-on reliability evaluation. Warranty Direct, an extended used car warranty administrator, looked at over 450,000 vehicles they covered in the United States and United Kingdom.

They looked at the repair records of 3- to 9-year-old automobiles and tabulated all of their claim records. And what can be more definitive than real people, putting mileage on real cars and encountering real problems?

2009 Nissan Altima

The results show the number of claims reported for every 100 vehicles (again, 3 -9 years-old) covered by Warranty Direct's policies.

And just so you understand what the numbers mean: Mazda, with a score of 8.04%, would mean that nearly 92 percent of the Mazda cars covered experienced no mechanical failure of any kind ... pretty darn good. In other words, the percentages below reflect what percentage of the vehicles that did have a mechanical problem. So, the more claims, the more widespread the problems.

Here are the results:

  1. Mazda - 8.04%

  2. Honda - 8.90%

  4. Mitsubishi - 17.04%

I think the main takeaway is that while some used vehicles have had fewer problems than some others, they all have potential problems going forward. So, it is extremely important for buyers to always do their due diligence. This would include:

Even with all the above, there are no 100% guarantees, but by doing all of them you are putting the odds greatly in your favor for making a solid used car purchase.
