1 Engine Knocking Noise problem

Failure Date: 03/10/2021

While driving on the highway at 70 mph I heard a knocking sound, there were not any warning lights on. I turned down the radio and a/c so I could hear it better, moved to the right lane and slowed down, a red oil light flashed on briefly and the knocking got very loud. I exited the highway at the next exit approx. 1 1/2 miles down. I pulled over and turned the car off, had it towed to the Hyundai dealership in venice. 2 days later they told me it had no oil in it. 5 days later they said it needed a new $8000 engine! I have always kept up with the maintenance and oil changes. I was 2000 miles over this time, but that should not leave 0 oil in the car. Approx. 60,000 miles on this vehicle. And if oil was getting low why didn't any lights come on.

2 Engine Knocking Noise problem

Failure Date: 07/29/2020

My engine, without any prior warning signs, suddenly started to make a knocking noise approximately 5 minutes after driving it. Within a few miles on the highway, the sound got louder and heavier, and the acceleration became very weak. I pulled over and stopped the car. When I tried to restart it was so hesitant to do so that I called for a tow. Upon inspection the engine was considered dead and had to be very expensively rebuilt. I keep up with my regularly scheduled oil changes and have maintained the car properly for the duration of my ownership. This malfunction came out of nowhere and was no fault of my own.

4 Engine Knocking Noise problem

Failure Date: 04/15/2019

I am told I need to have my engine replaced. My car had been making ticking and knocking noises as if it was struggling to function. The day it broke down, it was beginning to knock exceptionally loud. I was afraid it was going to stall while driving as the car would not accelerate when I pushed on the gas pedal. It stalled again at the next intersection. Then would not start at all. I had to ask for help to push my car to a safe area. This happened on a city streets. I had the car towed to the Hyundai dealership believing it was covered under warranty. I was told I needed a new engine at a cost of about $8,000. If I replace the engine with the same engine, who's to say this won't happen again? I bought the Hyundai because of the 10 year/100,000 mile warranty knowing I'd be putting on the miles for work. I don't expect engine failure at the 78,800 miles (I bought it used from enterprise car sales with 18,000 miles on it). The selling point was the 10 year/100,000 mile warranty that I expected to have. I learned it does not pass to the second owner. Why not? how does the driver change the apparently defective manufacturing of the engine?! as I pressed on with the Hyundai representative, he told me (after consulting with his supervisor) it is only covered for a second owner if it was a certified pre-owned vehicle. I said it was cpo and that is how enterprise marketed their vehicles. Hyundai then said the ownership for the warranty is under alamo/enterprise, not me. News to me, but, again, why does it matter if the engine is defective? these "nu" engines have already been established to be defective. What engine bites the dust at 78,800 miles? my car was serviced regularly although not by the dealership. The representative then proceeded to tell me the warranty would be invalid anyway if it was not serviced by Hyundai.
