Fiat Chrysler's Dodge and Kia Motors topped an initial quality study of new vehicles sold in the United States based on owner responses, industry consultant JD Power said on Wednesday.
The study examined problems experienced by owners of new 2020 model-year vehicles during the first 90 days of ownership, and determined their initial quality based on the number of problems experienced per 100 vehicles.
General Motors' Chevrolet and Fiat Chrysler's Ram tied for the third place.
The study found most domestic brands, including Fiat Chrysler's Dodge, Ram and Jeep as well as GM's Chevrolet, Buick and Cadillac, ranked above average.

GM's Chevrolet Sonic achieved the best score for individual model in the study.
"Collectively, this is the best-ever performance by the Detroit automakers — when compared with the import brands — in the history of the study," JD Power said.
The consultant added that most premium brands ranked below average, as they generally equip their vehicles with complex technology, which can cause problems for some owners.

One-fourth of all problems cited by new vehicle owners related to infotainment, including complaints about built-in voice recognition and touchscreens.
Tesla Inc made its debut on the list with a score that suggested 250 problems per 100 vehicles. However, the electric car maker was not ranked as it did not meet the required criteria for a comparative study.
"Unlike other manufacturers, Tesla doesn't grant us permission to survey its owners in 15 states where it is required," said Doug Betts, president of the automotive division at JD Power. The study found that GM's plant in China, which makes the Buick Envision, was building vehicles with the fewest defects or malfunctions.
