Owner report 11730504 · 2026-04-10 (April 10, 2026)
This is a hybrid vehicle. It has Dual clutch transmission. Since I have owned it, intermittently the clutch does not disengage completely. This causes the vehicle to try to pull ahead but my foot is on the brake. The vehicle does not stall. Somehow it figures out it can't pull ahead and somehow fully releases. I have brought it to kia at least 3 times. In each case they tell me they cNt get the car to fail and since there are no codes produced they can't fix it. They even held onto the car several days. I asked them to please replace SOMETHING…

Owner report 11600985 · 2024-07-10 (July 10, 2024)
I was backing out of a tandem parking spot in a private garage and got too close to a pillar, and tried to pull forward into the spot. It felt like the car got snagged on the pillar, but while pulling forward slowly, the gas pedal snapped off and the car accelerated quickly and uncontrollably. I was able to avoid hitting other cars but drove straight into a concrete wall despite immediately braking. I'm relatively uninjured, but if it had happened in a less controlled environment and/or I hadn't reacted as quickly, there could have been serious…
