Failure Date: 02/11/2015

Oil leaked from valve cover onto alternator. Engine stalled and left me stranded on rural mountain road. Finally got towed home. Mechanic says it will cost nearly $1000 to replace valve cover gaskets and alternator. Car is 2006 Hyundai Sonata with 3. 3l 6cyl engine. I believe that this is the same engine and same problem that prompted the recall on 2007 Hyundai veracruz NHTSA campaign number: 14v415000. The existing recall should be expanded to include more Hyundai vehicle models that exhibit the same problem.

Tell us what happened: bought vehicle new and regularly had serviced by dealer. Vehicle died without any warning coming off highway and I had to turn flashers on and place in park to restart. Engine started knocking with no warning and no warning lights illuminated. Had towed to dealer and was told engine had no oil and requires an engine change. Where did it go? there has never been any signs of smoke, burning smell or leaks anywhere and no warning lights ever giving indication of a low oil or low oil pressure indication nor any other engine light warning. Now dealer says we have to convince regional manager that this was not neglect on our part to have covered under the 100,000 mile power-train warranty.

Driving while using cruise control at approximately 65 mph the check engine, air bag, and e. S. C light illuminated. Also, a simultaneous internal engine explosion resulted in an instant fire as well as a rod thrown from the vehicle damaging block and setting the car on fire from a resulting massive oil leak. There was no prior damage leading up to the incident nor any indication to my knowledge that there were any concerns with my car till it was too late unfortunately.

The system warning lamps illuminated, then the engine shut off and would not restart. Evaluation showed that the alternator had failed and was covered with engine oil which had leaked from the front valve cover gasket onto the alternator. This failure is the same as NHTSA campaign number 14v415000, which covers another Hyundai vehicle.

Cars valve cover and or timing cover leaks on the alternator causing the alternator to be "soaked with oil "(dealers words). At any time thereafter the alternator could fail causing the engine to stall and causing injury. Hyundai refuses to replace the alternator but is replacing the alternator in the 07-12 Hyundai veracruz under recall with the same engine design and the same alternator placement. I have 2 cars an 08 and an 07 Sonata that both had the same problem. Why does Hyundai want to recall the veracruz and not the Hyundai with the same problem? the car has been in 3 times for inspection and a call to Hyundai on 04-13-2014. Hyundai refuses to replace the alternator.

Oil pan rusting out. A lot of engine motor oil seeping out of entire oil pan. Professional mechanic states this is not normal wear and tear at this low mileage. Eventually oil will leak out causing engine to seize and fail.

Failure Date: 01/30/2014

This is a new Hyundai Sonata 2015. The engine check light came on and the engine started running erratically. The following symptoms can be a safety concerns: 1. Sometimes when idling at intersection the engine rpm goes up all of a sudden and the car starts moving forward and only a stronger push on the brakes stops the car from crashing into the vehicle ahead or running a red light. 2. When driving on highway the car lacks power even if the gas pedal is depressed all the way into the floor. This prevents the car from properly accelerating when merging into incoming traffic. I took the car to the dealership and they identified the issue is "cam cover leaking" and "oil coming through the oil seal making the motor do weird things". These are the quotes from the paper I got from the dealer. The car spent 2 weeks with the dealer. They replaced the cam cover. But 2 days later the problem appeared again. I'm afraid of driving this car now, because engine behaves erratically. And this car only has 3500 miles on it.

On thanksgiving evening November 28, 2013 @ 7:30 pm, my 2011 Hyundai Sonata that I purchased new, caught fire on I 95 while driving it. The car has only 30,350 miles and is properly maintained and garage kept. The vehicle had the oil and filter replaced 5 days earlier and there are no signs of any fluids leaking in the garage. There were no warning lights that came on and the temperature gauge read as normal until just before the engine shut off (then all the dash lights came on) and we pulled over onto the shoulder of a busy highway at night. I raised the hood, smoke poured out and I could see small flames under the engine. Minutes later the flames were 20 feet high and the entire car burned until fire trucks and police arrived on the scene. The vehicle is a total loss.

No oil in the engine. No indication of oil leakage. No low oil pressure or low oil light indicating there was a problem with low oil. The Hyundai dealership has told me I need a new engine. The was no indication that there was a problem with the car until the car suddenly stopped functioning. This is a problem with this automobile. I've seen the same type of complaints on the internet. The Hyundai Sonata should be recalled to fix the malfunctioning warning system indicating that there is a problem with low oil pressure or low oil level.

I purchased my vehicle in April 2012. Car has been serviced only by brandon Hyundai service center. Last service was done on 7/25/2014. On August 31st my car cut off while driving. Car was towed to brandon Hyundai. On sept 5, I received a call from service dept saying diagnosis found the engine was locked up. They couldn't tell me why because it had oil and no leaks. It would have to broken down to find out why engine locked up which would cost me $500-$600. Also, a used engine would cost me $6200. On 9/15/14, I called Hyundai customer service at 12:27pm and spoke to esperanze. I explained to her my situation. She advised me to call back with id# and speak to a case manager. At 12:29pm, I called back and spoke to case mgr mariatta. She stated she could do nothing for me and referred me back to the dealership to have diagnosis done. I explained to her that I didn't have $600 to pay for diagnosis. Case#6878995. She stated that maybe dealership could help me with some arrangements since warranty recently expired and told me to have a good day. I am currently driving a loaner car. I need Hyundai to take responsibility and please get my car repaired or another car. Thanks so much!.

First time noticed that the oil pan is leaking at 15,042 miles. Took the car to the dealership and they resealed it under warranty. Started leaking again at 22,566 miles and took it to the dealership. This time they replaced the oil pan and resealed it again under the warranty. I just noticed it that it's leaking again at 30,660 miles. I am really concerned that this brand new car is leaking oil like this. Also, I strongly feel that the fix is not addressing the underlying issue which may be something else. I think Hyundai needs to look at this issue closely and must come up with a permanent solid fix. I have been reading on the Hyundai Sonata forum that many are facing the same problem. I am surprise that there is no recall for this yet. This is my first and last Hyundai.

2011 Sonata turbo purchased brand new by a family member maintained and garage kept. In March of 2013 and with 76,364 miles on the car I experienced what Hyundai categorized as a catastrophic engine failure. There was no indication of any problem, no warning lights, the engine spun a rod bearing and threw a piston rod through the block. The vehicle was towed to a dealership, assessed and determined that the engine would require replacement. During the repairs, a long block engine was put in the vehicle and when cranked at the dealership, vibrated so bad that they determined the replacement engine was not functional. A 3rd engine was placed in the car and at 85,960 miles on July 29, 2013 the 3rd engine did the same thing as the first engine, no warning lights, no indication anything was wrong, spun a rod bearing and threw the same location cylinder piston rod threw the block and in this catastrophic engine failure, the car caught on fire. Fortunately it did put itself out. Vehicle was towed to a different Hyundai dealership, assessed and determined an engine replacement was required. Hyundai is still unable to determine the cause for both catastrophic engine failures. 24 hours after the vehicle was returned w/ replacement motor, my garage floor and driveway were covered in motor oil. I was told by the dealership to fill the oil level and drive the car in for assessment. It was determined that the oil sending unit tube was not properly threaded into the engine block, causing the leak. The dealership said the engine came from the factory that way although they did make the repair. Now the car is out of warranty (surpassing the 100,000 miles) and I am left wondering how long this engine will last and how much a replacement will cost me. After consulting an attorney Hyundai is only willing to settle this for about 1500. 00 (not including legal fees).

Failure Date: 06/06/2003

I had my bearings replaced, my rear hub bearings. Now it is making to same noise and they now say it is not the bearings-they do not know what it is! my car idle sounds like is going to stall all the time when I am stopped. The car pulls around 5,20 and 50 mph like it just cannot get gas or the transmission is bad. I brought it in 2xs. They say they do not know what it is and cannot get anything on the diag machines. Now I am passed 60,000 miles. After having my car for 2 days (giving me no lender or rental) they found a problem at the last minute. Oil leaked from the valves into the spark plug wires into the coil pack and that is the car pulling problem. They say I have to pay $600 to fix it. This was on June 6,2003. I brought the car in for the idle which was not fixed and brought it in for this engine hesitation 2xs. Both times they did not and couldnot fix these problems. I have the receipts that they could not fix nor repeat these problems, but they are noted. I should not have to pay for these repairs!!!! this is not daily upkeep!! this must be defect!! I have a real problem with this car! I need to be contacted on this matter for Hyundai to pay for these repairs! I am having a difficult time on this matter. These parts need to be replaced now and I cannot and shouldn't have to pay for these parts or labor! I also have had my front driver window regulator fixed 4 times, my front passenger side regulator fixed once, my rear regulator fixed once. I had to buy a new battery for my car and a new headlight in the first year(Hyundai said I had to submit paperwork to see if they would vote to repay me for my cost of the battery). I had my air bag light going off(which now I never trust for it to go off when needed or even go off when not ). My paint is chipping everywhere! my front passenger window leaks all over my carpet inside floor. And many more problems! thank you, darlene liddane dliddane@earthlink. Net 941-637-0802.
