2011 HYUNDAI SONATA Engine Problems

My vehicle has an excessive oil consumption issue that started approximately in September 2021 after I got an oil change and had to put more oil in it after about 2 months when the oil change light went off. I have taken the vehicle to 2 different mechanics and they are unable to find an oil leak. There has been no oil leaking on the ground, no burning smell, no smoke showing, but the oil is somehow being consumed rapidly. The check oil light has not gone off since. I literally have to check the oil level every 2-3 weeks to check the levels. I got another oil change in February 2022 and have had to put 12 quarts in since that time. In July 2022 my car started driving funny with low power issues and the check engine light came on. I had the spark plugs and coil packs...

Engine knocking. If engine would’ve turned off it could have caused an accident. Yes, problem has been reproduced. Component has been inspected by dealer. No, warnings.

Around 174,000 miles, the motor started knocking, the engine blew, metal shavings in oil.

We broke down in the middle of the highway where there wasn’t a emergency lane available. A another vehicle struck the car in the rear .

The vehicle has been slowing down and failing to drive. Took it to the mechanic and the vehicle caught on fire. The mechanic said other vehicles had the same issue. When I called Hyundai they said my VIN was not apart of that recall and they can only go off of that. I have a vehicle that has been sitting for a long time unable to use because of engine problems that Hyundai is well aware of.

My engine seized while I was driving a few miles from home at 104,000 miles. I was told by the mechanic that there was not enough oil in the vehicle and that caused the problem. However, I have never missed a maintenance on this car and it was only 4,000 miles out of warranty. I don't understand how the car could have no oil. I checked and I was just a few hundred miles passed the date for an oil change but I never received any light indicating that oil was a problem and I cannot understand how the car could be using that much oil without me having any prior indication from the car.. just the engine seizing and now I am told the car is toast unless I put in a new engine! I don't see my car on recall but it seems that I have the same...

I was attending a wedding on 7/01/2022 as I was leaving for dropping my child off at the hospital as I was leaving to go change clothes my car had shut off in the middle of the road without no warning of what so ever it started smoking and wouldn't start or do anything for me to get out of the road which could've cause a bad wreck thank God for some gentleman helping me getting out of the road I have had mechanic look at there so many problems he don't know where to begin and I just spent out money fixing my car

Approx. 6/8 While driving car, engine ceases, had towed to mechanic shop, Towne Hyundai dealer advised have car again towed to them. Dealer advised needed oil change receipts for 69,000-90,000 which they received, I had been calling to check status several times. Called 7/1 advising I’m inconveniencing everyone using their car. Was advised they had to now remove valve cover & send pictures, they were waiting for Hyundai’s response but later on Towne left me voicemail they were trying to get me a rental car, none were available but probably on Tuesday they would have better luck. Well got the call today (Tuesday) it was denied for coverage due to maintenance on the vehicle …. So my car which I take great care of I was told there is no one that they could respond to with my dispute! Gave me Hyundai csr service # , I called & was...

Going down the highway at 70mph the engine just shut down. I couldn’t drive over 35 mph hr.

My engine seized up on me while driving in heavy traffic. I just purchased this vehicle in April 2022, and other than me having to replace a headlight, the car drives smooth and has never stalled or given any check engine, or oil lights, or any type of indication that there was something wrong with my vehicle. I just drove it and out of the blue my dashboard lights go off and my engine locks up while I'm driving. I wasn't able to get the car back started. I had it towed to a shop and they weren't able to get the engine to turn either. I am now resorting to a Hyundai dealership to inspect.

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...

The car began exhibiting a knocking noise on 5/21/2022 when increasing speed up to around 60 mph. Vehicle did the same thing again on 5/24/2022 and was shaking for a few minutes around the 50-60 mph mark. I took it to my local mechanic who drove it 6 blocks and then towed it back to his shop because he "didn't want to be the one to blow the motor out." At that point there was a consistent knocking noise in the engine even when in park. I did some research and discovered the "engine rod bearing failure" recall associated with similar model and year Hyundai Sonatas. So I had my car towed on 6/2/2022 to the nearest Hyundai dealership from Alpena, Michigan to Traverse City, Michigan, where they ran the engine rod diagnostic test and my vehicle failed the test. So the service rep at the dealership informed me on...

Upon accelerating to enter traffic the engine stalled. Subsequent attempts to restart the vehicle have been unsuccessful. The engine will not turn at all. A mechanic determined the engine was locked. Prior to this the check engine light had been on and the defective part had been replaced based on diagnostic code P0449.

The engine failed going down the highway and wouldn’t go over 30min. The engine needs to be replaced agin. But the dealership won’t because there are no open recalls. They should replace with a working engine.

The contact owns a 2011 Hyundai Sonata. The contact stated that while his son was driving at approximately 65 MPH, blackish smoke began to emit from the engine without warning.

Engine-locked up(with oil inside) Gearshift-does not change to next gear unless I use emergency shift lock.

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...

Had took it and called servals times to dealer complaining that something is wrong with the engine all they said is get a new car even thou was still making payments and told me warranty was not covered. After waiting a year later asked again and said warranty was covered due to the recall but when I took ot they denied my engine replaced saying I caused the head gasket to be replaced. Explaining the car showed no signs of over heating and just shut off once I got off the exit.

Driving down the road my car just shut down and wouldn't start it happened once before but I was able to jump it and it worked but this time after we replace the battery and got it running there was a knocking under the hood that sounds like a rod going out or the engine is toast. There's no knocking before the engine totally just shut down it was running perfectly fine and because it started and ran fine the last time the car just died when I was driving I thought it was the battery and low and behold I replaced the battery and it turns on perfectly fine but now the knocking in the engine. It also will not drive over so many miles per hour cuz if it goes up to those miles per hour then it shuts down or the knocking gets louder and it starts...

This vehicle's engine made a rattling noise and then suddenly stalled while I was driving it. I had it towed to the closest manufacturer dealership and the mechanic submitted a claim on my behalf to the manufacturer. It denied because the car has a salvage title. After reviewing your website it looks like the manufacturer can not solely deny a recall claim based on salvage title. This vehicle's engine has acted just like all the other recall's on this manufacturer, make & model.

My engine has failed due to a well known manufacturing defect. I never received the recall notice Service Campaign 953, as I am not the original owner. This Theta engine is part of a class action lawsuit and Hyundai is aware however they may try to not pay for a replacement engine according to the dealership. Please assist. Thank you so much.

My engine seized-up at approximately 125,000 miles. We were on the highway traveling about 75mph and heard an unusual sound from the engine compartment. We exited the highway on an exit ramp and at the stop, I hit the gas and lost most power - could only go about 15mph tops. Had to have it towed to my local Hyundai dealership and they determined that the engine was seized. My check engine light and low oil light were on when the problem presented. This was on 03/12/22. Thankfully this occurred when I and a buddy were traveling home from a basketball game, however, the primary driver of this car has been my 18 yo daughter - I'm SUPER glad it happened on my drive and not on hers.

The contact owns a 2011 Hyundai Sonata. The contact stated that upon pulling out of a driveway, the vehicle began to stall as he placed the vehicle into drive (D) and depressed the accelerator pedal. The contact then stated that several warning unknown lights appeared on the instrument panel as a dark colored smoke began to emit from underneath the hood of the vehicle. Due to the failure, the contact had the vehicle towed to an independent mechanic where they diagnosed the vehicle with engine failure. Upon investigation, the contact discovered NHTSA Campaign Number: 15V568000 (Engine) which he linked to the failure. The dealer was notified of the failure and provided him with a diagnostic fee. The manufacturer was not notified of the failure. The vehicle was not repaired and remained in the possession of the independent mechanic. The failure mileage was approximately 188,000.

As I was driving to work Saturday 3/12/22, four blocks from my home my Sonata with 064,000 miles stalled. I was able to restart the engine twice after which it made a lot of noise and, according to my mechanic, locked up. The mechanic tried to rotate the motor from the crankshaft pulley bolt and no movement, locked up. We suspect the failure may be connecting rod bearings premature wear, as has caused engine damage in the Sonata Hybrid currently on Recall. How can we determine the cause of this failure, and request satisfaction from Hyundai?

While driving, the engine in my 2011 Hyundai Sonata hybrid with the 2.4 liter engine shut off without notice (depressing the gas pedal and zero power)! I found myself and family in a difficult and potentially deadly situation as the speed limit on this road was 55mph, a large heavy duty tri axle dump truck was bearing down on my coasting car and family. I had few options from a safety stand point and had to make a snap decision. There was not a berm to pull off the road to the right side without trying to make a crash stop into the wilderness, or try to coast to the next available side street to get off the main road. As the vehicles coasting speed decreased I was very lucky that the oncoming traffic had a small gap between a another truck and a car. With few options I had...

Out of the blue, in the middle of driving, this car stopped working. This could have been a very dangerous situation. There was absolutely no warning. Apparently, there is a recall, but it has not been publicized by Hyundai. Why was the recall not registered with the NHTSA? What efforts have been made, IN EARNEST, by Hyundai to reach owners? What advertisements, social media posts, outreach by dealers have been made? How many letters has each owner been sent, and how clear and serious was the wording on these letters? We had no idea there may be an issue with the engine, as we never received a notification from Hyundai. We never even heard of the recall until the car died in the middle of driving it. It is very dangerous that this issue exists and that no earnest effort has been made to notify the public. Not only are...

The shifter is not being recognized in park by the motor therefore, it is not wanting to start. Once i do get it started, then i can not shift out of park i have to stick the key down in the shift unlock position to get it to move out of park.

Engine knocking noise, random acceleration, vibration. Car diagnosed for misfiring in the third cylinder. Hyundai warranty is not covering and the dealership states my additional engine life time warranty not covering either!

Driving down highway the car just stopped going. The steering wheel got increasingly harder to turn. Once on side of road, I noticed a bunch of the warning lights lit up the dashboard. I turned off the car and tried turning it back on, however, it would just make a weird clicking noise and not start. I scheduled an appointment with a Hyundai dealership, so I’m not sure what is wrong with car.

The car stopped while driving. It have a knock sensor code problem replaced and it will not start or move. I have read about the engine recall and my car did everything the engine recall stated. I do not understand how on one site it says my engine was recalled but on your site it does not. It has the same engine and model, make, and year. I could I could have died. I was never notified about any recall.

I was driving my 2011 Hyundai Sonata home from work when without warning my car started making a rattling noise and slowing down. I was able to get out of traffic and luckily maneuver my car into the parking lot of a mechanic before it completely shut down. I tried multiple times to restart it and it would not turn over. I started checking things under the hood and when checking my oil noticed it was completely empty. Where did all my oil go? After being inspected by the mechanic he notified me that my engine had seized up and that it is a known issue with this year and model. I then had it towed to the dealership where it is still sitting to be looked at. It’s been a week of me being out of work due to not having a vehicle. When I asked about the known...

While driving the car and accelerating the car literally stalled going down the street. I came to a complete stop it had died. No power or anything. I thought it was the starter but it wasn’t brand new starter. Come to find out the engine stalled. Lifted the hood nothing but burnt smelled and smoke. I’ve been catching [XXX] with this car. Helpppp me! It’s toooo many of us to be going through the same [XXX] thing and no ANSWERS! INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

As I was driving the vehicle, I had just exited off of the highway and onto a ramp and as I tried to accelerate the speed back to the speed limit my vehicle made a knocking sound and stalled at about 40mph. It would not speed up and as I kept driving to attempt to get home we could hear different sounds coming from the engine. I made it home as the vehicle seemed to be ready to complete shut off but didn't. I took it into Hyundai and they said it could be the turbo, but were unsure. They state there are no recalls on the vehicle, but it seems that this is a common issue for others with the same vehicle. The engine is not good and I cannot drive my vehicle safely.

I was driving my car regularly one day and out of nowhere my car just shut off. When I started it back up I heard a knocking noise and it got louder as I went faster. So I pulled over and checked to see where the sound was coming from and it came from the engine. So when I started the car back up, on the way home the car was hesitating to move right and kept jerking. I also noticed the engine light and engine oil light came one so I went to go check it out. When I did the shop said the engine is blown and that there are recalls on my type of car. When I searched to see if there was I found out my car had none. But the exact same thing that happens to those cars happened to mine.
