Vehicle was in motion and engine began knocking. Stopped driving it. Removal of engine has shown that it has thrown a rod and spun the insert out of it. This has happened on other hyundai vehicles but the recall isn't going back far enough.

The engine started making metallic clicking and knocking noises about a week ago. I took it to my mechanic and by then it started squeaking and squealing. He said it was catastrophic engine failure and asked if I had ever let it run out of oil, which I never did. When driving to my mechanic, lost a lot of power on an entrance ramp to highway and almost got in an accident. My mechanic never seen in an engine with < 200,000 miles unless an oil event, so he believes this was due to a manufacturing defect. It is interesting that the 2011 and 2012 sonata was recalled for exactly this type of issue as well. I wonder if the problems were also existing on previous year models, such as the 2007 model.

At 107,000 miles the engine started ticking. I drove to the dealer and the first mechanic who listened - didn't even open the hood, just listened said "you need a new engine". Cost of engine replacement with labor was estimated $4000-$5000 which was more than the car was worth, so I drove it another 20,000+ miles with the ticking getting louder until one morning it blew a hole in the block on the freeway. I've heard of this with other people and there low mileage sonatas. Seems to me hyundai is refusing to address the issue of a bad engine - this was a single owner 7 year old car with the original battery. Yep, the battery lasted longer than the engine!

Had just had my car smog checked, oil checked, tires rotated and began my drive from san diego ca. To san antonio tx. I get to ozona tx I hear a clinking in my engine. I pull off the freeway and the car dies, the car behind me almost hit me my car is towed to the hyundai dealership in san angelo the following monday, and the mechanics said it was low on oil and the engine had seized. I could not afford to have an engine put it in at the time, as it is an expensive engine costing 5, -$7,000.00. I had the car towed to san antonio tx where by a mechanic who said it was low on oil (had just had oil changed @ hyundai). He added more oil. The people at hyundai said they changed the oil and got the car to unseize and turn on but it was knocking. My car was later taken to am aamco, where the mechanics looked at it and found parts falling off it as they removed the oil pan. They called hyundai, because another can just like mine came in that day with the exact same problem. The person at hyundai said there is now a service bulletin out on the car but it has not been voluntarily recalled as of yet, because not enough people have stepped forward n filed a formal complaint. They do know that there is a problem with the way the filter soaks up the oil in the engine. It happens with no warning. No indicator lights came on in my car...no engine light, no oil light, no overheating or smoke or anything. Was running fine, and died. In this horrific place I've been put in, being stranded in a small texas town for a weekend, then another, and having to pay for rental cars, towing, multiple mechanics, I have learned alot about the car. The engine (according to hyundai)is expensive because they didn't make very many. It costs more than the v-6!! Many people have had the same exact problem with their cars, its all over message boards online and known among the salvage yards, machinists etc.

Driving on the freeway, I heard a clanking noise. It got very loud with acceleration. There were no indicator lights on, or over heating, smoke, or any signs of a problem other than the noise. I pulled off the freeway, and as I did so, the car died. Long story short, (as this has now been a month of a nightmare) the mechanics at the hyundai dealership said it was very low on oil. I drove from san diego and was on my way to san antonio, so of course I made sure the oil was okay before I left. I had just paid my tags and had it smog checked and oil was checked and fine. Since speaking with many mechanics, I have found it is a well known fact that this engine is defected and has not been recalled yet because not enough people have filed formal complaints. The engine itself is more expensive the v-6! I've been told that the car runs fine, and all of a sudden dies because of a problem with the filter sucking up oil. The hyundai dealership changed my oil and my car turned back on, knocking, but on. I had another mechanic look at it, and he said there was no oil in it, so I know the filter is sucking it up. I only realized this problem after seeing many many people complaining on cars.com chat boards, of the same exact thing happening to them, and from hearing about it from different mechanics I've spoke with. The last mechanic I spoke with at aamco, called hyundai and they told him about the problem and why it has not yet been recalled. I only had 117,000mls on it. That may sound like alot to some, but I've owned many cars and they have all last much longer (a toyota @ 334,00). This problem has cost me my job I moved to san antonio for, as I am new to the area and cannot be financed et. And owe 4,000+ on my sonata still. Its cost me tons of money out of pocket, towing, mechanics, rentals etc. And physically made me ill. A new or rebuilt engine: 3,000-7,000!
