When considering a Kia Sorento, there are certain model years that may present more issues than others. Among them, the earlier years, particularly 2011 and 2012, have been reported to have more frequent problems with engine and transmission issues. Additionally, the 2016 model year has seen complaints regarding premature brake wear and electrical system malfunctions. When inspecting any used Sorento, regardless of year, it's crucial to pay close attention to common issues such as engine noise, transmission smoothness, and signs of rust, especially in regions prone to corrosion. Checking the vehicle's maintenance records and having a trusted mechanic perform a thorough inspection can help identify any potential problems before making a purchase.
