NHTSA Complaint #11645188 — 2024 KIA EV9

When driving over uneven surfaces, like typical urban and suburban roads and highways, the rear end seems so wobble and slide. It feels like the heavy EV is about to break traction and slide sideways. It porpoises as well. It makes every passengers heart skip a beat. These are on dry roads, obeying speed limits, with the stock tires. An expansion joint, seam of two types of road material, utility cover or other irregularities can cause this. Easily reproduced but dealers or Kia America don’t seem to believe or care.
