2021 JD Power Dependability Study sees Lexus, Porsche and Kia coming out on top

The 2021 JD Power Dependability Study features data from owners of three-year-old cars.

Lexus has been in the top spot on the list for 9 of the last 10 years.

Porsche's 911 is the most dependable car overall.

Kia improved its score overall to snag third place.

Toyota continues to rank highly on the list, thanks to high levels of fit and finish.

Buick also typically does well, which makes sense given its lack of distinct models but focus on luxury.

Cadillac consistently offers above-average build quality in an American luxury car. 

Hyundai interestingly didn't see the same kind of uplift that its sister-brand Kia did, but stills ranks highly overall.

Genesis may be a new brand, but it is doing well despite its focus on tech.

Lincoln's brand renaissance has seen it back on top of the American luxury heap, and thankfully, a focus on build quality has come with it.
