Ok, I'm hoping to get some help from this forum. I had my 2017 Hyundai Santa fe sport knock sensor recall done in Aug. A week later it went into EPM. They replaced the wiring harness. Well now 1500 miles later its gone into EPM again. I'm getting no answers from Hyundai as of right now. I'm still under the power train warranty only. The dealership will not give me a loaner car. Because they say anything could be wrong with it and I might not be covered with my powertrain warranty. They say they did a test and couldn't find anything. So they are waiting to hear from Hyundai to see what to do next. From what I read about this knock sensor recall. If the sensor detects a problem with the engine. It will put the vehicle in EPM and the engine light will blink. So why are they saying they don't know what is wrong with it. Here I am on day 2 with out a car to drive and no one will give me any answers. What is everyone's opinion on this. And if your vehicle went into EPM more then once. What ended up happening to your vehicle?
