The 2018 Q5 is the launch year of the second-generation Q5 in North America. It uses the EA888 Gen 3B 2.0T paired with Audis 7-speed S tronic (DL382) dual-clutch transmission. Most complaints relate to the redesigned MMI infotainment, fuel-pump issues, and minor electrical gremlins typical of launch-year German SUVs.
Launch-year Q5 has more software gremlins than 2019+. Mechanically the EA888 is mature; software and MMI are the real concerns.
