NHTSA Complaint #11520663 — 2014 KIA SORENTO

The engine seized up. The issue may be due to a design problem with all Kia engines. Here's what the service technician at the Kia dealership told me: 1) There is a pin on the cam shaft that keeps it in place; 2) Over time it moves, and gets sheared off; 3) When the pin is sheared off, the cam shaft spins out of time; 4) That causes the valves to slam into the pistons and bends the valves; 5) After the valves are bent, the engine has no compression; 6) The engine needs to be replaced or the car needs to be junked. The service tech says he had seen it happen quite a bit with all Kia models. In other words, it's a design flaw. There are other ways to keep the cam shaft in place, which are used by other manufacturers.
