Engine makes a very loud noise and cannot be used. This car was very well maintained and just out of warranty. Loud noise in cylinder and crank shaft. Hyundai says engine needs to be replaced. This can happen to anyone who would be left stranded or in a bad situation. Hyundai does acknowledge a problem, but so far no recall.

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 the tire replacement service at about 61k miles (very gentle, first owner, still had more than 2/32 tread left on the factory tires at 61k miles) I was told by the technician that the rear break pads have to be replaced. With in 2 days I took the car to aamco since there was a $35 brake pad service deal. I was told after inspection that a caliper piston is seized and so the calipers, the damaged rotors and of course the brake pads have to be replaced - preferably for booth rare wheels, in order to have similar braking characteristics. While it is common sense that the front brake pads would wear faster, the aamco folks were surprised to find the rear brake system in such a bad condition while the original front brakes were still good. Per their opinion it is mostly due to a manufacturer defect. I called hyundai warranty immediately, they provided a case number, but I was told I was out of luck since I am just past 60k miles and also there is no recall specific to rear brakes that will address my concern. With this I thought I lost all my bragging rights about hyundai - on their reliability and value for the money. Moreover, this is unbelievable since on a 1997 nissan altima which I own, I still have 25% left on the rear brakes at 125k miles. Shortly later I found scores of sonata owners who complained about this issue in the internet forums as well as the federal safety agency site. I also found complaints about sun visors not staying in place, hanging loosely, a hazard while driving. I have this problem too but never payed much attention to it. Currently I am not in a position to shell out over $600 dollars to get the rear brake issue fixed to be able to take myself and my family safely in the car. I hope my complaint breaches the threshold and the federal safety agency takes action to have hyundai fix the issue at hyundai's cost asap. Thanks for providing me this opportunity to log the complaint.

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!

Case no. [xxx] I purchased my 2007 sonata from the denville, nj dealership in may 2007. With only 38,000 miles on odometer I had the scare of my life.driving on the highway, the engine died, and I lost all power. The 'check engine' light came on. Thankfully, I was able to pull to the shoulder of the road and safely stop the car. After 2 minutes I tried to restart the car. It started and I drove it home with the check engine light still on. I checked that all fluids were ok. Next day driving to work, coming down a long grade, car engine died and again I was fortunate that I did not get into an accident. I brought my car to a aaa service station and reported the problem. They checked and informed me that the problem is due to the throttle position sensor,(tps) which they found a tech service bulletin describing the symptoms and condition. They gave me a copy of said bulletin. They noted that even if they installed the part, I would have to have a hyundai dealer perform ecu software update. Therefore, I brought the car to the dealer and had them make the repair. I expected that this would be a 'recall' by hyundai, as failure of this part could be life threatening, as it was in my case. They said they could not honor any warranty service and I was charged $252.24. I requested and received the replaced part.. I am rasked hyundai motors of america to show good faith to a loyal customer, by reimbursing me for the costs associated with this known failing part.. Their response:" tsb are not recalls. Dealers are made aware of these and are asked to perform them on affected vehicles when they come in for other service. I vehicle outside of warranty, then the repair is an out of pocket cost to customer. They apologize for the inconvenience this may have caused." they refused to reimburse me saying this part was not a recall. How outrageous of them!

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.
