2023 Hyundai Tucson

The 2023 Tucson draws the most complaints around its forward collision avoidance system and powertrain behavior. Owners frequently report the automatic emergency braking activating without an obvious hazard present, no vehicle, pedestrian, or obstacle in range, causing sudden, hard stops at highway and city speeds. A smaller but consistent group reports fuel and propulsion issues, most commonly the engine stumbling, near-stalling, or lurching forward unexpectedly at low speeds or while stopped, sometimes without any warning light. Transmission complaints also appear across multiple reports, with owners describing a rubbing noise that worsens over time and, in some cases, eventual transmission replacement under warranty. A smaller cluster of electrical system complaints rounds out the picture. One report describes a loss of steering response while cornering, where the wheel moved normally but the vehicle continued straight rather than following the curve.
