My mechanic also mentioned that this was 2nd 2018 hyundai sante fe in the past week he had to replace the starter on that vehicle had 60,000 miles. There were no warning lights prior to the event, I suspected it was the starter after having a new battery installed and no success starting because of the lights that remained on on the instrument panel.”

“The oil pressure switch has a faulty seal causing oil to leak out onto the engine block. This causes oil on the underbody and ground, smoke amd smell from oil on got surfaces, knocking noises from the engine, reduced power or hesitation, illumination or the check engine light and oil pressure light, high speed stall, and will also cause fire in the engine compartment resulting in death or sever injury. I have taken my car to the Red McCombs Hyundai dealership in San Antonio TX for repair and they have confirmed that it is the oil pressure switch seal that failed. The oil leak has also damaged electrical components causing a malfunction in the dash cluster and steering wheel control.”
