When choosing their next car purchase, consumers are often looking for the vehicles that will run as smoothly as possible and cause them the least amount of headache.

According to the results of CarMD.com Corp.’s 2013 CarMD Vehicle Health Index and Manufacturer & Vehicle Reliability Rankings released Wednesday, Hyundai has risen to the top in this respect, ousting Toyota from its 2-year stint in the No. 1 spot.

Rounding out the top five “healthiest” and most reliable automakers are Toyota, General Motors, Chrysler and Honda, respectively.

Interestingly, half of the top 10 manufacturers (Hyundai, Toyota, Nissan, Kia and Volkswagen) experienced a drop in reliability rating, with more frequent visits to the repair shop and increased average repair costs.

The other five (GM, Chrysler, Honda, Ford and Mitsubishi) saw improved ratings.

The No. 3 brand — General Motors — saw the biggest boost, moving up from a No. 8 ranking in 2012.

Coming in at no. 10, Mitsubishi ranks in the top ten for the first time this year.

As far as cost goes, GM owners saw the lowest average repair cost among the top 10-ranked manufacturers at $304.99.

Interestingly, Toyota had the highest overall repair cost at $540.53. The five vehicles with the highest average repair costs were Toyota Prius hybrids, which contributed to Toyota's rise in average repair cost, CarMD reported.

Though Hyundai pushed Toyota from the No. 1 brand ranking, for the third consecutive year, the top-ranked vehicle is a Toyota, with the 2012 Camry ranked as the most reliable vehicle for 2013.

And the Camry isn’t the only Toyota vehicle to have held this spot.

Previously, the Corolla ranked No. 1 with the 2009 Corolla and 2010 Corolla earning top spots in the past two CarMD rankings.

This year’s top 10 list of most reliable vehicles includes four sedans, four compacts and two SUVs.

Interestingly, Nissan, a brand that didn’t make it into the top five brand rankings, led the pack with five vehicles, including the 2012 Altima (ranked No. 2), 2011 Rogue (No. 5), 2012 Rogue (No. 6), 2012 Sentra (No. 7) and 2011 Sentra (No. 9).

Toyota has three cars in the top 10, including the 2012 Toyota Camry (No. 1), 2011 Toyota Corolla (No. 3) and 2011 Toyota Camry (No. 4).

Hyundai, this year’s top-ranked brand, only has one vehicle on the list — the 2010 Elantra, which came in at No. 8.

Mazda also made the top 10 list for the first time with its Mazda3 (No. 10)

The index also ranks the top three vehicles by category: compact, minivan, sedan, full-size SUV, wagon/crossover, truck and luxury.

The 2012 GMC Sierra, ranked No. 1 in the truck category, pushing Ford from the top spot, which it held last year.

And that wasn’t the only upset.

In the luxury category, Buick and Lincoln unseated Lexus and Infiniti with the Buick Lacrosse, and 2010 and 2007 Lincoln MKZ vehicles.
