The list has a good bit to do with JD powers being biased, but keep in mind the list covers all models not just a specific one. And if one model sells more or has a higher total number of problems it effects the entire brand in the listing. That being said. Toyota does not make everything perfect. So it makes sense, for example any Toyota’s not made in Japan tend to have a higher frequency of issue, the same can be said for Mazda and other Asian brands. Assembly in Asia tends to be good compared to assembly in Mexico or the u.s. That being said tho my understanding was the Chevy Silverado was itself at the at the top end of the most likely to have warranty work required based on that year model vehicles. So Chevy’s getting pulled by other models then their trucks and ev’s.
Have a 21’ J Vin premium hatch. 16.3k miles and got it new. No problems yet with mine.
