I have around 36,000 miles on my SUV and my engine went out. I was driving home and it started making rug a loud knocking noise. Half way home it died and the oil light flashed but went back off. Car started right back up but knocking sound was still there. Knocking sound occurs when accelerating.
Engine failure at 121k miles. I drive long distances for work so the miles are super easy not stop and go. I noticed a knocking noise at certain throttle pedal positions, I pulled into a gas station and checked the oil and it was barely touching the dip stick so I bought a quart of oil and this put the level in the middle of the acceptable range on the dip stick. I proceeded to get somewhere closer to my home. As I was driving on the interstate the check engine light came on and started blinking so I got off onto the exit and at the top the motor made a hard noise and stopped and all the lights came on the dash and smoke came from under the car. There was oil on the ground so I assume the oil pan had a hole from a rod failure. I change my own oil every 7500n miles when the factory setting tells me it's time. I use mobil 1 synthetic oil and a good filter every time. I had the oil changed the first time at Hyundai of ontario, calif and the second time at jiffy lube in redlands, CA. The price for synthetic oil change was ridiculous when I can do it for half minimum. Hyundai has said since I have no invoices for oil changes they will not cover motor fully? I know the computer can be accessed to see the dates when I reset the meter miles. I know since doing my research Hyundai has had the very same problems with prior year cars. I believe they should pay for this problem a car like this should last well into 200 to 300k miles when taken care of properly. I have had a Honda and Toyota that did high mileage with no problems. Hyundai still has a problem with the 2. 0 liter motors. The warranty needs to be made longer to 200k miles if they have really fixed the problem with this motor. I will never buy or recommend a Hyundai vehicle to anyone!.
