The engine oil pan was resealed five times and still its leaking. When they resealed the second time, they replaced the oil pan as well. After that it was resealed three more times and the car is at the dealer for sixth reseal. They are replacing the pan again. The brake caliper pistons are exhibiting excessive rust which I have not seen in my life while owning and maintaining various cars. The field engineer is saying that its normal and I don't agree with that. What I have seen based on that it's a design flaw. The caliper piston should be pressing completely against the brake pad surface area where as small portion of the caliper remains in non contact with the pad and the salt and slush during the winter gets into it making it rust which will impede the braking operation in future and may cause a fatal crash. Attached photographs are showing pack rust inside the piston on both the driver and passenger side.

Hyundai installed faulty oil feed pipe to the turbo in Hyundai Sonata 2011 2. 0t, the pipe leaks and results in low oil in the engine, which causes engine failure. I saw the oil leaks on the parking spot. Took it to the mechanic and the pipe was at fault, my engine oil was at critical level, provided that I had it changed about 1000 miles.

On lambda/lambda ii mpi series engines, engine oil can leak onto the alternator, which could affect charging system function and potentially cause the engine to stall and not restart. This would result in a loss of motive power as well as affect power braking and power steering system function, which would unexpectedly increase steering and brake pedal effort, potentially increasing stopping distances and the risk of a crash causing injury and/or damage to property. Every make/model of vehicle that has this engine has oil leaks on the alternator and other critical components (I've replaced 3 alternators so far! ~$200 each! + labor!!!) yet only a certain year of the "vera cruz" received a recall because the cost to Hyundai would be higher to fix this issue on all affected vehicles (azera, sante fe, and my Sonata etc. Models).

Oil pan has been leaking and resealed four times. After first two times the dealer replaced the pan and resealed it again. It started seeping again and I am sick of it. The oil pan has been leaking since the car had only 7000 miles on it and I bought it brand new.

My vehicle has been an issue since I purchased it. I have taken it in five times for the same issue with the sunroof leaking and damaging the interior of the vehicle. I have also taken it in for replacement of cv joints twice and as of yesterday for the third time with no resolution. When I dropped off my vehicle it was fine with no lights, no oil change light on or anything, but they called to let me know I had sludge in my engine and it is going to lock up on me. My bumper to bumper warranty will not cover it so I will need to pay out of pocket to fix the issue on a brand new car . I have also had to change my tires on the car at least eight times in the last 3 years. I purchased a warranty for tires and rims, but as usual they have loop holes. They promised I can change my rims if I had any scratches, but when I tried to change them, they have denied my request for three years. It is frustrating to know that what they promise is a lie.

Oil leak from engine valve cover - left (front) side of 3. 3 v6. This is directly above alternator. Eventually alternator fails due to severe oil/dirt contamination. First noticed when battery light comes on at idle, showing charging problem. By then damage is done. Valve cover must be replaced along with alternator or problem will quickly recur. *there is currently a recall for Hyundai veracruz with same engine for the same problem. Sonata is not included, but a quick internet search shows this to be a common, well-known problem for many years.

My father in law who is a mechanic changed my oil on Sunday. My husband and I have one car so I left vehicle home so it could get changed. Monday 7/14/15 I drove car to work which is 10 mins from home. I drove car home from work car was fine. When my husband drove the car back from the store and he said that he went to accelerate the car did nothing. There was no warning lights or anything. My husband had to coast all the way into driveway. In October of 2014 I had the starter replaced by the dealer under warrantee and 6 recalls taken care of. During that time they had broken the whole frame of the car and I was with rental for a week and a half. So at this time I thought that the starter went again. I had to wait until Friday to take the car to the shop since I was 484 miles over warranty and had to pay for diagnostic. Left car at dealership at 8:30am. They had not gotten back to me until Monday 20, 2015. The called to tell me that it was the starter which would not be covered and OH yeah you're engine has seized, and OH yeah you're car has been leaking oil profusely. I explained that the car had not been leaking the entire time it had been sitting in my garage nor did it leak on the tow truck. And then I asked how can an engine seize at 60000 miles. They want to charge me 8000 for starter and remoded engine and 6000 for new engine and starter. I am not replacing engine with another failed engine. I am going to seek advice from lawyer. Thank heavens my husband was not driving on major highway when engine cut out. Completely ridiculous. Had salesman told me about these issues when I bought the car in March of 2014, I would not have purchase the car. I think it is a lack of ethics.

Driving down the interstate I heard and felt a faint puddering. I looked down and my oil light was on. I was able to immediately exit. As I was going on the off ramp the check engine light came on. I was able to barely pull into a park and ride. 20 minutes later oil was everywhere. The car never overheated, and there was a trail of oil from the road to my car. Since I had taken it to the get the oil changed just on the 5th of may, just 10 days earlier. I had the car towed to that facility. The piston internally slammed through the engine punching a hole in the engine wall, and leaking oil from the engine. The engine did not cease. Pieces and parts of bolts and side wall were found by the mechanic.

Driving down hwy @65mph. Car lost power. Was able to get to side of road. Car smelled and smoking. Checked oil. . . 2 liters low. Had oil changed 1000 miles ago. No oil light came on. Have been routinely checking my oil because 2 weeks after oil changed had car serviced for brakes and mechanic checked oil and was low. He put oil in. No oil leaks anywhere. Now I have to pay 4500 for another 2011 Hyundai Sonata engine which I really don't want to put it because there is obviously a problem with this engine and replacing with the same I will end up with the same problem.

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.

I purchased the 2011 Sonata certified used, plus I purchased the extended warranty. I was exiting the freeway when the car just died, no sounds, no warning, no check engine lights, nothing. I was able to coast to a gas station and I noticed a little smoke coming from the engine. I had it towed to a dealership and 2 days later they called & told me the engine seized, but the oil was only about half a quart low. The dealership wouldn¿t honor the powertrain warranty because they said it's limited to 60k miles (i¿m the 2nd owner & my car had 66k miles). I filed a claim with extended warranty service and they sent out an inspector. His finding was it was 2-3 quarts low, there was "sludge and metal bits" in the oil and we'd need a new engine. Because I couldn¿t produce the receipt from my last oil change, they cited owner neglect and denied the claim. I used royal purple synthetic oil (and have used this same oil for the past 15 yrs in all my vehicles). I changed my own oil in July, approximately 3 months prior. Note: there was never any oil leaks or stains on the driveway, no low oil/engine light at all. To replace the engine, it was going to cost around $6000. 00. I couldn¿t afford that, so I ended up having to get another car. Which sucks because now I am paying 2 car notes, on 2 cars, but I am only able to drive one. I don¿t want to mess my credit up by letting it go back, so i¿m really trying to hold on to it as long as I can, but I really don¿t know when i¿m going to have the extra $$ to get a new engine put in.

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.

There is an existing recall for the Hyundai veracruz (which also uses the Hyundai lambada engine). There is an issue with the valve cover leaking oil onto the alternator, causing the alternator to fail. This happened to my car a year ago (approx), and I paid to have the repair done. The leaking issue is starting to surface again, which caused me to look online for how widespread this issue was. That was when I discovered the veracruz recall.

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).

Valve cover gasket and timing cover leaking oil on the the alternator. Was fixed by a Hyundai dealership in August 2013 for ~$1,800 (including an new alternator). Now experiencing the same oil leak onto the new alternator just over a year and a half later and less than 20,000 miles later. 5npeu46f26h038399 2006 Hyundai Sonata GLS 3. 3l v6. Why has there not been a recall for this and why are dealerships only trained to fix the resulting symptoms and not the underlying problem that caused the leak to start?.

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.
