Consumer Description

The vehicle is demonstrating clear signs of engine failure based off the symptoms Hyundai states on its website for the rod knock bearing recall (no power, enters limp mode, white smoke out tailpipes, etc.) Hyundai states vehicle passes testing. Engine also has oil consumption issues, has had its PVC value fail twice in ten months, and burns through 1.5 qts of oil every 496 miles (has failed all 3 consumption tests). The vehicle has stalled out on multiple occasions and risked my/my child's life, has required cylinder cleanings and fuel injection cleanings, and the engine gets extremely hot. This is the second failed engine in the Sonata, and Hyundai has not stated if they will replace it.
