The contact owns a 2007 Hyundai Sonata. While driving 40 mph, the engine seized and the check engine and oil warning indicators illuminated. The vehicle was towed to an independent mechanic who diagnosed that the engine needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was not made aware of the failure. The failure mileage and VIN were unknown.

The issue is the tensioner for the timing chain. The tensioner failed, causing a very expensive engine repair. There is a recall on the 6 cyl tensioner, but not the 4 cyl which I have. My research says the same tensioners were used for both engines. It failed at 169,000. It was stationary in a parking lot when it failed to start. It would turnover but would not catch. I have all the damaged parts saved by the mechanic. If I was driving when it failed, it would have not only blown the engine but most likely would have stopped my car on whatever road I was driving on, including an expressway.

This car has the front valve cover gasket leak that other Hyundai vehicles with the V6 engine. It only leaks right in the same corner as all the others and it leaks right on to the alternator. I am on my second maybe third alternator. I ahve been lucky enough to have it not cause any injury's so far.

Same problem as described in 14V415000 Hyundai veracruz recall. While driving the ESC warning light on, then intermittent battery + seat belt indicating alternator failure, caused by leaking valve cover. Can cause sudden failure. This defect is not isolated to the veracruz and perhaps the recall should be broadened

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.

Traveling at 50 mph highway off ramp. A rattling in the engine - broken rod - loss of power and no acceleration.

Numerous issues from almost day one with this car. 1) within less than a month after purchase of this vehicle, passenger airbag light was coming on even with someone weighing well over 100 lbs in seat. Dealership brushed it off as 'someone sitting in the seat incorrectly'. the light stayed on for so long, with the dealerships refusing to do anything, that we feel it eventually burned out. 2) engine light came on very early in ownership as well and dealerships refused to resolve. Had to have fuel system replaced at one point because car completely died while driving with plenty of fuel. 3) replace headlamps, brake lamps, and tag lamps on a regular basis. On at least a monthly basis we are replacing 1 or 2 lights. We've been pulled over numerous times because a light has failed. 4) driver door automatic lock no longer works. 5) airbag light on driver side came on around 2013 or 2014 and remains on. 6) passenger side visor doesn't stay up when not in use. Driver side visor is starting to do the same. 7) passenger seat belt light constantly flashes even when seat is empty.

I am reporting this because I see other models with the same engine having the same problem. My valve cover gasket leaked oil onto the alternator and caused it to fail prematurely. This has happened in April of 2014 and has now happened again in June of 2015. Other models utilizing the same engine have been recalled due to this problem. Will this model be recalled?

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!

We were driving highway speed when all of a sudden the cars check engine light, ESC light came on while in the middle of traffic and the motor completely shut off causing no steering or any control of the vehicle, was able to coast to the side of the road and tried restarting the car with no luck. Called the dealership immediately and they stated it had done that to the previous owner but was not warranted to be fixed, but yet we only purchased this car 6 months ago. Sat on the side of the road trying to figure out what to do, when the tow truck came by and scanned in which I got the following codes: P2106, P1295, P2135. Its a sensor on the accelerator pedal and causes the car to shut off immediately because it cant respond to the throttle body. This is very dangerous as we could have been rearended and seriously injured. Please contact asap!!!!!!

The car was making a noise when I started it. The noises got worse as I drove to work. Then the car died twice while in route on the interstate. The oil light came on. The heat gauge was normal. I notices smoke in the rear view mirror. I turned on the hazard flashers and began to get to the shoulder of the road. When I stopped the smoke got worse. I called work. The dotd roadside assistance showed up. I got out of the car and walked back toward him. He asked where my purse was. I turned back to the car and noticed flames coming from under the hood. He got my valuables out of the car, called the fire department and police. The flames were several feet high by the time they got the fire out. I called a tow truck. A fellow worker came and took me to work.

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. 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!
