New report: These are the 10 most reliable vehicles on the road


If you’re shopping for a used car, you want to find a vehicle that won’t cost you an arm and a leg in repairs.

CarMD.com has just released its 2017 CarMD Vehicle Health Index, which ranks brands and vehicles for frequency of check engine light problems and average cost of repairs for various makes and models.

To come up with the rankings, it analyzed the check engine health of 4.2 million model year 1996 to 2017 vehicles.

Here are the headlines from CarMD’s 2017 Vehicle Health Index:

  • Acura was the brand least likely to need check engine repairs over the past year, edging out Honda (#2) and Toyota (#3)
  • Hyundai is the brand with the lowest average repair cost ($306), followed by Mazda ($310) and Kia ($317)
  • Volkswagen is the only brand to rank in the top 10 on both lists
  • The 2013 Honda Civic is least likely to need check engine-related repairs, followed by the 2015 Toyota Camry and 2015 Toyota Corolla
  • The 2012 Mazda 5 had the lowest average check engine light repair cost ($109)

At least 10% of the cars and trucks on the road in the U.S. have a check engine light on at any given time, the study found.

One important note: CarMD says a loose, damaged or missing gas cap is one of the most common check engine light triggers, which is the case with the 2012 Mazda 5.

That’s why vehicles with a high percentage of finicky gas caps often have lower average repair costs.

Clark’s used car buying tips

Money expert Clark Howard recommends that you buy a car that’s two or three years old because brand new cars begin to lose value the second they’re driven off the dealer’s lot.

With a used vehicle, you don’t eat that depreciation — a key benefit to buying a pre-owned car.

Once you find a used car, follow these steps:

  1. Check the vehicle history report. Run the VIN through CARFAX.com to find out if it’s a flood vehicle or if it has been in a horrible accident.
  2. Have the used vehicle inspected by an independent mechanic. One of the key things to know about buying a used car is that you buy “as is.” CarFax alone is not enough of a check; you need to take this additional step.

Finally, arrange auto financing in advance! Look at credit unions, online banks or even traditional banks. Only take dealer financing if it beats any other offer you have.
