NHTSA Complaint #11511730 — 2014 HYUNDAI SANTA FE

The oil needs to be changed monthly due to an engine issue. Recently the car went into engine failure despite regular maintenance. The engine's constant need for monthly oil changes due to a bad engine causes the car to go into "limp mode". This feature causes to car to immediately decrease speed endangering the people in the car and those around them as it is an uncontrolled decrease. The issue has been confirmed and inspected by a dealership, a third party chain maintenance company, and an auto repair company. The check engine light comes on everytime the car needs an oil change which is more frequently than the manual recommends. The check engine light comes on monthly as does limp mode however prior to the engine failure another dealership was not able to properly diagnose the issue as an engine issue. A recall has been issued for issues related to the engine previously and other makes of the same year have been recalled due to engine issues. This model was the only model not recalled despite similar issues.
