The Hyundai Tucson has developed a mixed reputation over the past decade because of recurring engine and transmission complaints across multiple generations. The most serious issues involve engine failures tied to Hyundai's Theta II engines, particularly in 2011-2021 models. Owners have reported excessive oil consumption, knocking noises, sudden stalling, and, in some cases, complete engine failure caused by connecting rod bearing problems. These issues became significant enough to trigger major recalls and warranty extensions, which helped many owners financially but did not exactly inspire confidence.
Transmission problems are another major weak point, especially in models equipped with Hyundai's dual-clutch transmission. Many drivers describe jerky shifting, hesitation from stops, delayed acceleration, and abrupt low-speed behavior that can make city driving feel awkward and unpredictable. The 2016-2018 models tend to receive the most criticism for these transmission quirks. Even newer 2022+ Tucsons, despite their redesigned styling and upgraded interiors, have generated complaints involving engine hesitation, sudden loss of power, or stalling while turning or accelerating. These newer problems are not as universally catastrophic as the older Theta II failures, but they remain a notable concern among owners.
Electrical and sensor-related complaints also appear fairly often. Issues range from infotainment glitches and warning lights to overly sensitive driver-assistance systems that behave like nervous hall monitors. Hyundai has issued multiple recalls over the years, including recalls involving ABS modules that could potentially create fire risks, which is why checking recall completion history is extremely important when shopping used.
The upside is that many affected Tucsons were covered under Hyundai's long powertrain warranty, which softened the financial impact for original owners. Still, the frequency of complaints has made reliability one of Tucson's biggest discussion points. Later models from 2019-2020 and the redesigned 2022+ generation are generally considered improvements overall, but buyers should still prioritize maintenance history, recall verification, and a thorough inspection before purchasing.
