2011 Hyundai Sonata engine complaints
Page 7 of 35: complaints 161 to 190 of 1,012, newest first, as owners wrote them.
I would like to report a serious Safety Hazard. Hyundai Motor America replaced my 2011 Sonata's defective engine in January 2020. The new engine turned off on its own approximately 20 times without the "Check Engine" light turning on between August 2021 and January 2022. The "Check Engine" light did not turn on until January 24, 2022. I had my car towed to El Cajon Hyundai in August 2021 after the engine turned off on its own while my car was traveling more than 40 MPH. El Cajon Hyundai could not diagnose the cause of the problem in August 2021 because the "Check Engine" light never turned on each time the engine turned off on its own. I had to work when the non-flashing “Check Engine” light finally turned for three days starting on January 24, 2021. The engine turned off on its own approximately 20 more times from January 27, 2021 until July 22, 2022 without the “Check Engine” light turning on. The “Check Engine” light finally turned on again on July 22, 2022, but it was not for Crankshaft Position Sensor. I told the mechanic what my Sonata has been doing since August 2021 after he initially could not diagnose the problem. The mechanic checked the computer again and he was able to locate the Check Engine Light message for the Crankshaft Position Sensor that occurred on January 24, 2022. I paid El Cajon Hyundai $593.71 on July 25, 2022 and July 29, 2022 to replace the Crankshaft Position Sensor. Unfortunately, my car turned off on its own again on July 30, 2022 and August 13, 2022 after the new Crankshaft Position Sensor was installed. My 2011 Hyundai Sonata has been posing a serious safety hazard for me each time I turn the engine on since early August 2021. Hyundai Motor America is ethically and financially responsible for ensuring that my 2011 Sonata is safe to drive. I am also concern that this serious safety hazard may be impacting other Hyundai owners.
On March 5, 2020 I was entering a highway and increased my speed a little so I can get into my lane. After I made it into the highway my car lost power in the middle of the road and immediately would not go past 20 mph. I had to drive slowly and get all the way over into another lane and stopped in a nearby neighborhood. I went to not having any dashboard indicators to now a check engine light, oil light, and ABS. I checked my dip stick to see how much oil did I have in my car and I was completely empty but I was not due for an oil change yet. I had to get my car towed to my home. The next day, we tried to let my car rest so it sat. On that Morning, I drove my car maybe 8 minutes up the road to stop at an auto zone place. There weren’t any dashboard lights so I assumed my car was okay. The representative did a diagnostic on my car and he said he didn’t find any problems except I needed my brakes worked on & I didn’t have any oil. He put new oil in my car and told me I should be able to drive it up the road to my mechanic. I let my car run a little with the oil topped off and maybe drove no more than 15 minutes before those previous dashboard lights appeared on my car again and my car stopped power and wouldn’t drive any more than 20 mph. Long story short, I had to get my car towed twice since then. To my mechanic and then to the Hyundai dealership in Gaithersburg, MD. The rep. at the dealership said her mechanic recommended that I get an engine combustion cleaning, a new pcv valve and a oil change because I didn’t have any oil in my car. I told her that was weird because I had put oil in my car from the auto zone place and I believe my car must be leaking oil. Today, August 15th I am still having problems with running out of oil before my oil change mileage and date and I am not having any indicators on my dashboard to alert me. This can cause me to drive around without knowing and my engine can lock. That is a safety issue!!
The car started having issues like turn off itself while running and the oil warning lamp lights up. It did that twice then the engine burst on the third time. Oil leaked on the ground in the middle of the freeway, I am lucky I didn't get myself into a bad accident.
No warning lights on. Police and Fire department inspected car. Car towed as total lost. Safety was at risk per car caught fire while been driven
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 replaced. Now I'm dealing with low power on inclines and the catalytic converter now needs to be replaced. The mechanic believes it's due to the excessive oil consumption issue. It's my understanding that several Hyundais have been recalled due to excessive oil consumption issues. The contact has stated that during one incident, the vehicle lost power going up an incline. The oil levels were checked and were normal. A tow truck mechanic was able to get the vehicle started back up so that the contact could drive it home. The contact took the vehicle to a mechanic and was told the catalytic converter was bad. Unfortunately, the part is on back order and the vehicle is unable to be repaired. Aside from the catalytic converter, the vehicle has an oil consumption issue.
Around 174,000 miles, the motor started knocking, the engine blew, metal shavings in oil.
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.
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 problem of many other people and I feel that Hyundai should make this problem right and fix it.
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 advised when Hyundai denies coverage that is the final decision & there is no dispute & no one else to speak to. I was advised I could call the Better Business Bureau & given the # to call. When this first happened I went on the site where Hyundai was being fined & put my vin to check , it showed I should’ve been art of the recall, now after I’m denied the status changed! I advised the rep at Towne after he said I was denied I was part of that recall & I checked he said I wasn’t, so I feel like things were altered , I took a screenshot of my vin covered, is there anything else I can do or speak to on this, I’m so upset!
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

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 photos I have attached, I also have videos that I am not able to upload.
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 6/3/2022 that my car failed the test and would be receiving a full engine replacement and knock sensors with the 10-year warranty.
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.

When driving, I would get an unusual loud alarm sound, then the car start to cut off, couldn't stop the car using the brakes, had to wait until it slows down, usually when I'm in traffic, which is dangerous. This has happened several times off/on, I would get warning saying check brake, when all this is happening, no warning before the alarm sound or when the car has cutoff. Took car to hyundai in olive branch, ms on 04/22/2022, therefore it has not been repaired, I was not offered a loaner car, I asked for a loaner, she (lexi) quickly said "they don't offer loaner cars" so I'm having to borrow a vehicle to get to work. I've called, left messages, no one has returned my calls.
While driving the car, the engine just stopped. We had to push the car to the side of the road and it would not start again. The car was towed to a mechanic and the engine had seized up completely.
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. His son immediately pulled over as his girlfriend and their dogs exited the vehicle. The smoke quickly turned into flames as the vehicle became engulfed in a fire. The fire department arrived at the scene and extinguished the fire. A fire report was filed and no injuries were reported. The vehicle was initially towed to an independent tow yard where they deemed the vehicle a complete loss. The contact spoke to several attorneys and was advised to keep the vehicle in his possession if possible. The contact then had the vehicle towed to his home where it remained in his possession. The contact's son notified the manufacturer of the failure and received no assistance. The failure mileage was unknown.
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 or replace anything when I took my vehicle in for recall (Recall 180). Please help!
We have refill engine oil weekly. After every oil change a month the oil is dark and a needs a quart more to refill. This is regularly since 2015. We purchased the car in 2012. 2019 the front ball joints started clumping in reverse, replaced in 2021. While driving on the freeway and exiting off onto a ramp the car dramatically down shifted and was unable to correct itself. Later discovered the computer module needed replacement. We still are refilling oil weekly. Not to mention replacing the clock spring twice.
