coincidentally after 11-months after a software update for that knock sensor now I do have a problem with that knock sensor by having to be replaced. Total cost of repair: $643.90 (Vehicle broke down, my SUV went into limp mode meaning loss of power/acceleration, I needed a tow. The engine malfunction indicator light in the dashboard was blinking on & off.)

Got a recall notice about an engine component had it checked they said it was fine. 7 months later it lost power and throw the piston through the bottom of the engine, oil and gas poured all over the road and we had just changed the oil. Called Hyundai and talked to them. They said it would be covered for a new engine cause they had lost a class action lawsuit. It wasn’t the matter if it went out but when it would go out. I towed it to Hyundai where it sat for 4 months before inspection. Then I was told it had to many miles on it so there for it wasn’t covered. But they was quick to offer to order me a new engine at my expense. My issue is a bad part is a bad part. Mileage doesn’t matter. They figured out what mileage most of them was going out at and set a lower mileage so they wouldn’t be responsible. I’ve only had the vehicle 4 yrs and I’m disabled.

I have a 2012 Hyundai Santa fe the engine started making knocking sounds and had loss of power. Did some research on the safety recall for the engine and found it on there site. Vehicle was taken to local Hyundai dealer like there site stated for inspection on 10/15/21. Dealership then called 3 hours later and said it was not covered and found noise coming from lower engine crank as stated on the receipt. I then filed a case file with Hyundai #18907069 and phone number 8334628722 ext 65091. After numerous calls and leaving messages I never once spoke to my Case manager. She said in a email that salvage title voids warranty, I sent evidence Hyundai calling it a safety recall witch is still covered. I received the email on November 24 haven't heard a thing since. There site said the engine can start on fire and could lock up at high speed causing a accident they called it a safety recall.

I was driving in colorado on I-70 and as I slowed down to exit, heard a clicking sound. The sound got louder/quicker when I accelerated. I pulled over and checked but saw nothing. I checked the oil and had a service guy at a superstore check it too. He saw no metal parts in the oil. No indicator lights were on. It was a sunday and nothing was open. I tried to drive farther and was going 35 miles per hour up a hill behind a truck but as soon as I tried to accelerate to pass, I heard a pop. The engine light and the oil light came up. I pulled over and tried to at least accelerate to the freeway exit, but had an immediate loss of power. I had to have the car towed twice - once to the closest town and then back to denver to the dealership (which was again closed on sunday). The tow truck driver told me there was oil everywhere under the engine. The dealership looked at it a week later and said there was a hole in the side of the engine block.

My 2012 hyundai santa fe I was driving home on the freeway, all of a sudden the oil light went on. So I immediately changed lanes to get off the freeway. I thought I need to get oil, than the engine light came on! I realized that I was losing power so got to the side of the road out of harms way. I tried to turn on the engine. There was nothing. I got towed to a auto repair shop. And left the car over night. It was so late to look at car. In the morning I called two different hyundai dealerships to get help on perhaps an engine recall. At both places the forward me to someone to help me, but both location hung up on me. So I paid a $500 fee to the repair shop to look at my car. They had to remove the engine and finally said it would need a rebuilt engine and labor at a cost of $6000. So I could afford that. A friend looked up my VIN number and that there was a recall on my car. Now I have to find a hyundai service who will fix my recall problem. I need to know what to do next.

I was driving my vehicle on the highway at 60mph. I was on a slight incline and proceeded to pass the vehicle in front of me. Upon arriving to the upcoming town I noticed a distinct loud knock in the engine compartment and loss of power, I immediately pulled in to a service station. The mechanic informed me that is sounded like a connecting rod and driving it any further would not be recommended. I was quite a distance from home and so with a tow service and rental car I paid almost $700.00 to get home with the vehicle.
