The primary areas where owners might encounter problems are related to the advanced Hydraulic Body-Based Suspension System, which can develop leaks, and certain electrical components, such as the infotainment screen and potential battery drain issues. Interior climate control actuators can also be a point of failure. While these issues are not universal, they represent the most commonly reported technical concerns for this model year. Regular maintenance and prompt attention to warning lights are recommended.
