What owners say

Mixed to positive sentiment overall, heavily dependent on model year and powertrain.

  • Very frequentElectrical/Infotainment glitches

    Includes infotainment screen freezing, frequent Bluetooth/CarPlay disconnections, slow system response, and various unexplained electrical gremlins. Primarily associated with 2021-2022 model years.

  • RecurrentPowertrain Concerns (Pre-2025 GT-Line)

    The 1.6L turbocharged engine is described as underpowered and sluggish, especially from a stop. General anxiety about long-term Kia engine reliability persists from past models, though the newer Smartstream engines (1.6T, 2.5L, 2.5T) are noted as improvements.

  • RecurrentTraction Limitations (GT Trim)

    Front-wheel-drive GT models experience significant wheel spin and torque steer under hard acceleration due to the powerful 2.5T engine and lack of a limited-slip differential.

  • RecurrentDealership/Sales Problems

    Poor communication, incorrect orders (wrong trim, drivetrain, or missing features), attempts to add market adjustments after agreement, and pressure for positive reviews.

  • RecurrentPaint Quality & Fitment

    Thin paint prone to scratching and chipping; specific mention of paint chipping on door edges where they contact hinge bolts.
