Extensive Mechanical & Electrical Failures* — A single, detailed report lists numerous failures including: power steering failure, heat shield rattling, heater core/intern cooler clog, sunroof motor failure leading to leaks, tilt/telescoping steering wheel failure, radiator failure, power steering rack leak, shift-to-park cable failure, gas pedal sensor failure, cracking dashboard, door window actuator failure, and engine timing issues. Frequency: isolated (as a comprehensive list from one owner), but described as "VERY common problems."
Oil Gallery Gasket Issue* — Mentioned as a known expensive issue affecting some VQ35HR and VQ37HR engines, potentially including 2012 models. Some experience failure before 100,000 miles. Frequency: isolated.
