We were on our way home from the children's hospital in philadelphia for my daughter (4 hours away from home) and my 2015 Santa Fe with the 3. 3l motor began to knock. My dad (who is very mechanically inclined) pulled over at a gas station and checked oil and other fluids. It was low, even though I just had oil changed 900 miles before and it was checked before our trip to the hospital. We bought oil and put it in. Knocking was still there but was not as loud. We got back on interstate. Few miles up the road it completely lost power, extreme knocking, no lights on in the dash or any gauges out of normal range. He checked oil and it was completely empty but there was no oil trail or anything. We coasted into a crossover and that's when he saw the connecting rod under the car.
The blind spot detector starting randomly going off very sporadically since we had the car. Then one day it started going off almost every minute for about 7-8 minutes then an error message appeared and it stopped working all together. The car was in motion on the freeway.
Oil consumption within 200 miles blind spot detection doesn't work.
