The Kia Sorento has been a family favorite for many, but there's been a lot of talk online about how reliable the Sorento is. There are some owners out there swearing by their Sorentos and saying they have had zero issues over the years. Some have multiple problems — minor annoyances to major mechanical failures. Whether these are isolated cases that get more attention online or widespread issues is hard to tell. The reliability question appears to be model year, trim level and even vehicle dependent. There are those who argue proper maintenance is the key, and those who argue there are inherent design flaws. So many conflicting experiences make it difficult for potential buyers to know what to expect.
