general problems of the 2011 Hyundai Sonata - part 1

The affected component is the engine/rod bearing (theta ii 2. 4l). My 2011 Hyundai Sonata stalled and the engine locked up twice in live traffic (March 2025 and July 2025). The vehicle is available for inspection if needed. This created a serious safety risk to me and others on the road, as the stall occurred on [xxx] at highway speeds. This failure could have been catastrophic had it happened on the DC/baltimore beltway or another high-traffic roadway. Hyundai’s system shows recall 132 was marked complete at very low mileage (around 32,000 miles), but my vehicle later developed oil consumption and stalling consistent with rod bearing failure. Capitol heights Hyundai noted a warranty pre-authorization (PA) in March 2025 and told me Hyundai needed my mailing address “for the claim,” but later said it was a typo and that no record exists. The dealership charged me for a diagnostic but did not inspect the vehicle for rod bearing failure, despite symptoms consistent with recall 132. Annapolis Hyundai, where the car was purchased as a cpo, has admitted they have no documentation that recall 132 was ever performed (no repair order, mileage, or technician notes). Yet Hyundai’s system shows recall 132 marked “complete. ” without proof that the ksds software or bearing inspection was done, I belive this recall should be considered open. Hyundai consumer affairs has stated that I must pay for towing and diagnosis before they will investigate, with possible reimbursement later. This conflicts with federal law (49 u. S. C. § 30120), which requires recall diagnosis and repair at no cost to the consumer. Prior to the failures, my vehicle had a history of oil consumption and “no oil on dipstick” findings, which are known precursors to rod bearing failure. No warning lamps appeared before the stalls. I am requesting NHTSA’s assistance in requiring Hyundai to provide documentation or reopen recall 132 and perform a no-cost inspection/repair to ensure this vehicle is safe to operate information redacted pursuant to the freedom of.

I had bought this car off facebook marketplace after confirming with my dad that it was a good car, when I had finally saved enough. After I took it home the check engine light had come on not too long after, the engine stalls when turning the key, pressing on the brake helps start the engine. Turns out the car was a salvage title and my dad didn’t know that and I didn’t know what that was.

I tried pumping gas and the car would not let me pump the gas into the car. I had to hold the the gas pump hose and pull the trigger myself to pump the gas, which would still make the clicking stop noise that stops the pumping of the gas. Then when I started driving, the check engine light came on. Went o'reilly to test the check engine light code and it popped up with a p0449 code for the evaporative emissions (evap) vent control valve.

My car will randomly shut off while I’m driving. My seatbelt comes undone my door has opened while I was driving down the highway.

Car spontaneously caught fire while turned on. First smoke started coming from under the hood. Within three - five minutes, the car erupted in flames followed by a minor explosion that burned more than half of the car causing a total loss.

I changed my oil on Saturday and it now has no oil. The engine light started flashing and my engine seized up. Now it does not run at all. It turns on halfway where the dashboard turns on but the motor/engine does not turn. It appears to be white smoke coming out of the car after trying to turn it back on.

I craig knight purchased the vehicle from a dealership mr. T’s world test drive the car was fine left the dealership had to go back he change the brake lights made it back left to go to the store the next day had to pull over they had smoke coming from under the hood open the hood up the wires was on fire.

My 2011 Hyundai Sonata engine failed in April 2023. Was towed and the engine was replaced due to the recall. Got car back November 4th 2023. Fuel gauge never went out and after driving about 3 miles the engine light came on. Dec 13th was driving on highway and felt like the car was going to fall apart. Able to get off highway only for the car to die. Every light including some I have never seen came on. Was stuck on the side of the road with my esa dog in 28°. Temp. For over an hour with no power and hazards starting to dim. I'm disabled and had no help. Local pd towed vehicle and drove me home. Car sat at tow yard collecting fees as I was waiting for the dealership to call me back. Finally got help with paying the tow yard company only to be stuck once again for over an hour in the cold and then denied a tow to the dealership since they decided to cancel my appointment by text while I was on with Hyundai roadside assistance. They denied any help. Luckily the tow yard felt bad and made a call for me and a friend came and paid the 160. 00 tow truck to get the car back to my house. They have now not returned my calls and the case manager has not responded as well. This is unacceptable. I don't have any money and I have no idea how they can get away with treating a disabled person in the winter days before christmas by letting me be stranded twice on the side of the road with an engine that has less than 10 miles on it.

My car caught on fire while I was driving it. I was put at risk of burning, and being struck by other vehicles as I exited the burning car. Warning lamps came on just as another motorist alerted me to flames coming out of my car. Fire department and highway patrol responded. Police report was filed. Insurance has looked at the car and declared it a total loss. Engine was replaced 7 months ago, under a recall for the theta ii 2. 4 engine.

1) fuel gauge readings are erratic, empty one minute then full the next then back to empty or in between regardless on actual fuel level. 2) safety at risk if fuel pump malfunctions and gas gauge readings erratic. 3) problem has been noted in numerous blogs, internet sites. 4) no open recalls yet this is a serious problem. 5) the only warning lights are fuel gauge flashes empty, but then goes away then comes back. 6) cause per blogs is defective fuel sending gauge on fuel pump. Mileage at approximately 128k recurring issue, fuel pump failure possibly at high speeds could cause deaths if vehicle out of drivers control.

I'm smelling has from under the car and it's got a ticking sound and burning oil it looks like.

I started smelling a strong fuel odor and my car just started leaking fuel while I was driving it.

While driving the vehicle on the interstate, crossing the expansion joint on an overpass, the check engine light illuminated. Immediately following, smoke began coming from under the hood. Pulled off the side of the road to check, and flames were coming out of the car. Quickly removed what personal items that were possible while the car started becoming engulfed in flames. The car burned until the fire department arrived and put the vehicle out. While we cannot be certain, it is believed that the high voltage wiring chafed and arced leading to the fire. If it wouldn't have been possible to immediately pull to the shoulder, the car would have been engulfed while rolling and could have lead to death. The car is a total loss.

2011 Sonata se 2. 0t door lock’s acting up won’t open or lock fuel smell in the car really strong and not measuring the gas keeps going up and down and at times I don’t even know if I have gas or not and when filling gas at the gas tank entrance where you fill up at won’t let me fill up gas keeps getting spit out when I’m filling and I have to keep clicking the gas gun and not put pressure have to fill it very slow.

In may 2022 the engine was recalled and replaced by schomp Hyundai located at 100 havan st, aurora, CO 80010, and I purchased this car right after the engine recall. Since I bought the car vehicle the engine has been making noise and the ac and heater smell gas and burned fuel inside the vehicle through cabin air vents. I took the car to the schomp Hyundai and asked them to fix the noise problem as the engine is not properly installed but they refused to fix it and asked me to pay $180 to diagnose the problem and to pay additional for the fix. The second time when I took the car for the gas and fuel fume and I was told that it is not part of the engine warranty; I have to pay $180 to diagnose the problem and pay additional for the fix. As the engine was replaced, the service may have resulted in damage to the high-pressure fuel pipe. While maneuvering the engine into place, the fuel pipe may have been crushed, poorly torqued, or simply not aligned properly. The dealer is not accepting any responsibility.

After doing some research, I am now aware that there was a recall 20v-746 or 21v-727 that my car was affected by & was never notified about. On 6/2/2022, I was driving and just exited the freeway. Smoke started coming out of the passengers side of the engine. Cars were honking at me & flames started coming out as I drove into a parking lot. I was terrified as my life was at risk & felt fortunate that this did not happen on the freeway. I feel lucky to have been able to escape this life threatening experience. There is now an open claim with my insurance. I had brake lights changed at frank Hyundai on 4/08/2022 in national city, CA where they also ran a diagnostic check on the car. There was never mention of a recall & my car was cleared of any issues. In addition to the photos I have attached, I also have videos that I am not able to upload.

When driving randomly the cars engine will rev really high while pressing the gas pedal but the car doesn't move. After a little while the car eventually makes a loud clunking noise which shakes the car and typically causes the tires to spin. It seems to happen when the car is trying to decide whether to switch the gas engine or back to ev mode. This has been happening for a long time an even after the engine was replace under the recall. This is a safety issue that causes major concerns for myself an passengers. Also it happen when turning onto highways or exits which at high speeds there is a high likelihood of causing an accident. I have reported this to Hyundai several times but they cannot figure out the cause but rather keep trying different things an charging me. The car also seems to burn oil fast which doesn't make any sense being that its a newly installed engine.

Hyundai recalled my vehicle twice for gdi engine inspection/replacement (recall 132). Subsequently, my vehicle was recalled a 3rd time for high-pressure fuel pipe inspection and replacement (recall 180). During this recall, the dealership inspected and did not replace or repair any equipment. 4/12/2022 I smelled gasoline and took my vehicle to an auto shop for inspection. The technician explained that the high-pressure fuel system was leaking fuel significantly and was an extreme safety hazard. I contacted Hyundai manufacturer right away due to my knowledge of recall 180. Hyundai set me up with a dealership service appointment and I had the vehicle towed to the dealership for safety. The dealership refuses to honor the recall (recall 180) and after several phone calls, emails, and tweets; I am still unable to get reconciliation from Hyundai consumer affairs. For context, please understand that this dealership is the same dealership that failed to repair or replace anything when I took my vehicle in for recall (recall 180). Please help!.

When fuel tank is quarter full, car shuts down when I make complete stops like on traffic lights or when turning. I have to turn it completely off and have gear on park and restart it.

My daughter and a passenger were driving our car at night October 3, 2021and the entire car suddenly and without notice began shaking and convulsing, became non responsive and all the electrical components and the engine went dead including inside lights, brakes, power steering and lighting system. It was nighttime and the traffic was medium but she was able to ease the vehicle onto the shoulder without incident but had a few close calls as drivers eased around her. They could have been severely injured by the traffic as it attempted to get past her on this narrow two lane road. The vehicle was towed to a mechanic who diagnosed that the engine had blown, was seized and locked up. He also mentioned that there is a recall for the 2011 Sonata and numerous problems such as this have been reported. We had no idea there was a recall on this vehicle. We are very concerned and upset that this incident could have caused severe injury to our daughter, her friend and other drivers around her. There were no prior notifications or signals with the car having any problems prior to this incident.

My engine keeps making a knocking sound. When I am driving it will reduce speed, and begins to idle while already driving. Which concerns me that these same issues occurred on my same year, make and model on my vehicle and some how Hyundai dealership will tell me that my car does not have a recall. 470,000 cars of the same year make, and model went in for exactly what my car is doing.

It's a if the gas isn't getting to the engine. Check engine light is on. The code had read p0451. .

On Friday the 13th of February while driving on a main intersection my car just stopped in the middle of the road. There was traffic on both sides of the road and of course people didn't have any patience and I was stuck and placed my blinkers on. And waited for aaa to arrive. The car was in motion and then stationary.

First I notice a smell of gas the see a leak under the car closer to DE rear passenger side big leak.

Driving car and it stalled and died. Engine making clucking sound. Had to tow to mechanic engine locked up. Also before engine failure car hard to start . The vehicle was in motion when died in the city.

I pulled into my driveway and as I put on the brake the car suddenly accelerated. There are skids marks on the cement showing the front wheels were locked from braking but the car continued to push me forward into the back of my Ford ranger. . The engine was revving and since braking was not stopping the car I shoved it into park. The car came to a halt but the engine was still revving and did not stop until I turned off the motor. An article on autowise. Com dated 10/26/2019 refers to this problem as "Hyundai's secret acceleration problems" and there are a lot of comments from about 40 different people talking about this type of problem. This happened to me once before but not with no damage. This could have been fatal if I had been in any other situation. It is time for a federal recall.

I have had issues with this vehicle since oct 2019. At that time I had a recall for the hard knock sensor after that it continues to give me issues. The check engine comes on continuously every week. I fix one issue then the lights comes back on for another. My car shakes while driving like engine wants to stop, doesn't want to accelerate over 40 miles in the middle of the highway streets it's not safe for a vehicle to stop accelerating without any warning theirs other bystanders that can crash into me. I contacted hynduai every month since oct urging them to do a full diagnostic cause my vehicle already has 13 recalls on it previously and I strongly feel this vehicle is one of the defective ones. Hynduai keeps turning their back on me and tells me I need to fix this then this then that. I also have a fuel smell and a evap code that keeps coming on which this recall was supposed to be fixed and if it happend again its guarantee to be fixed again. Hynduai told me no. They keep turning their back on me. I fear that my vehicle will cause harm to me and others due to the lack of Hyundai not taking my vehicle safety seriously.

Smell of fuel & starting issues. The car has been taken to the dealer multiple times regarding gas fumes and they could not find anything. And it is currently at a mechanic shop to for same reason. When you start the car it doesnt take long before the whole car smells like gas & the smell is so strong it is suffocating. The car is health & fire risk. Also the car sometimes doesnt want to start for days but the starter, battery, alternator all work & even the mechanic doesnt know whats wrong with it. Apperantly there is no recall & if you search online there are alot of people with same cars complaining about gas smell & starting issues. .

At 1st my car my consuming a lot of oil. I was going to get top off at my oil place every week. I tried to take it to my nearby Hyundai, they told me they wanted $350 to do a test. Then my car was not gasing the way it usually did. It was stalling, I had a burning smell coming from my engine. I took it to my mechanic and he replaced the O2 sensor, heating sensor, pcv valve, he did a transmission flush. It started to work ok, and I was driving with my disabled husband and our 4 year old daughter when the car engine went out on us on the highway. We got the car tow to our mechanic and its more problems then solutions . Its now the Cadillac converter, this car is extremely dangerous to drive. I have receipts of the repairs, towing and daily oil inputs.

I took my 2011 Hyundai Sonata 2. 0l turbo to my Hyundai dealership and had several overdue recalls done, one being a complete engine replacement. Upon receiving vehicle again, I then took vehicle to smog check center (California resident) and the vehicle failed in one category: liquid fuel leak check. I have read on NHTSA notices and other sites that certain 2011-2014 Sonata 2. 0l turbo and 2. 4l engines are being recalled for this very issue: confirming high pressure fuel pipe was connected by Hyundai dealer to high-pressure fuel pump outlet during engine replacement (recall 180). My VIN search states I have 0 open recalls though my vehicle appears to suffer from this exact issue.

Purchased 2011 Hyundai Sonata literally a week later, this happened. Unknown.

My 2011 Sonata suddenly lost power while driving at 65 mph after pulling over restarting car check engine light came on. Car only has 107599 miles.
