2012 Hyundai Sonata complaints

Approx july 2022 My sonata began to malfunction, first the steering wheel buttons stopped working intermittently off and on unable to turn on and set cruise control, unable to use hands free phone options as well as unable to navigate cluster features, as the time goes on the problem gets worse and eventually do not function ever. I replaced the steering wheel buttons which fixed the issue temporarily only now the vehicle will engage cruise control, accelerate dramatically and continue to gain speed. I am unable to disengage cruise control via the brake pedal, or cancel option or steering wheel. If I depress the brake pedal it will begin to decelerate but once I let off the brake pedal the engine will revv high and gain speed again. Buttons begin to function in a reverse order meaning press cancel, cruise turns on, press set button, cruise will set, press set button cruise will disengage etc. The only way to disengage cruise and rapid acceleration in this dangerous scenario is to Press the on off cruise control button. Immediately stopped vehicle had it towed to dealership, they stated that they could not replicate the problem, however their diagnosis for the problem was due to incorrect brake fluid put in the vehicle and suggested to completely replace the entire brake system of the vehicle I declined as I felt that was not the problem in fact bizarre diagnosis. Only hyundai dealership has ever put any brake fluid in my vehicle... this is completely dangerous as when vehicle

On March 19th, 2022 I was t-boned and my airbags failed to deploy causing me to slam my head against my window. I herniated two discs in my neck because of the accident. My 2012 Hyundai Sonata had just had it's engine replaced due to the engine recall and had also never been in a wreck. My airbag light came on after the wreck. Sent my car to be fixed and light went off. I was hit again 2 weeks ago and afain, airbags failed to deploy. Notified Hyundai of the situation and was told my car wasn't part of the airbag recall.

Fake Place and fake appointment. They give me an appointment after 1 month and I went to do the recall on the airbag unit they told me no part.Very bad experience

I purchased the car 9/1/21. 4 months ago I repaired an issue with the fuel pump and fuel rail. Now it's doing the same thing. Code P0087. I looked up to see if there were any recalls and there aren't any OPEN recalls; however the recall #180 is the issue I am having with my car. Would this be covered under the #180 recall?

I purchased my 2012 Hyundai Sonata on 4-7-22. The car has had no mechanical work, no accidents and has less than 1000 miles. On 9-16-22 i was driving my car home and was less than five minutes away on the highway. My car began to decelerate, I attempted to stop at a red light but my car would not give me control and the brake was rock solid and would not push down. I also could not turn the car off via the start button as the car would not let me. My engine ESC light came on the dashboard in red and the engine completely halted. To get to safety as i was on the highway with oncoming traffic i steered the car to the right on the ramp .I exited the vehicle as it began to smoke ,i thought it would catch fire so i moved far away and called my boyfriend for help and a tow truck to get the vehicle. The vehicle was towed to College park Hyundai 9500 Baltimore Ave., College park, MD 20740.I looked up my car and noticed there are recalls for this engine and a few other recalls as i told the dealership. The car is currently being inspected and the dealer said they would get back to me. Once the service department received the car they told me the recall most likely will not effect my vehicle. I don't believe that to be true and i was put in danger because of this engine issue with Hyundai.

My vehicle stopped in December 2020. The dealer, Hyundai of PR, did not issue a recall for this issue. I could have been driving on the highway and loss power. THIS IS DANGEROUS. The manufacturer should be Required to notify all affected Hyundai Sonata owners via all types of media. If I hadn't known about this recall I would have paid for an engine out of my pocket.

Vehicle caught on Fire.

The contact owns a 2012 Hyundai Sonata. The contact stated while driving at various speeds, and depressing the accelerator pedal the RPM inadvertently decreased. The contact stated that the traction control warning light was illuminated. The contact also stated that while exiting the vehicle he noticed that the brake lights were still illuminated. The contact called Cochran Hyundai of Monroeville (4520 William Penn Hwy, Monroeville, PA 15146:(412) 245-4380) and Bowser Hyundai (1001 Clairton Blvd, Pleasant Hills, PA 15236: (412) 469-2100) and made them aware of the failure. The vehicle was not diagnosed or repaired. Upon investigation, the contact associated the failure with TSB: 15-01-056; however, the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 50,500. The contact paid for the replacement of the defective part.

Car stalled several times for no reason then engine siezed

Brake lights stay on when the car is turned off. It is draining the battery and I cannot drive the car. No Hyundai dealers near me have availability until October or after.

When driving at higher speeds 50+mph, hybrid battery warning flashes, alarm beeps, warning states to safely pull over and stop. Warning goes away after turning the car on and off a few times. Dealer states they can not duplicate problem and can not diagnose. Have visited Dealer twice now with she results

The contact owns a 2012 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle stalled with the RPM increasing and the check engine warning light illuminated. The vehicle was towed to the dealer; however, the dealer had not yet informed the contact of the diagnostic results. The dealer requested the oil change maintenance records. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 101,000.

Driver’s side seat belt frequently unlatches on own while driving vehicle. This places the driver at risk for significant harm should this occur during a collision. This problem has not been inspected or confirmed by the manufacturer or other professionals. The only warning lamp possibly associated with this is the airbag warning lamp.

Engine failed while driving, causing vehicle to stall and forced to the side of the road while transporting children. I had vehicle towed to dealership and learned that this was a known manufacturing defect, one that I had previously had recall service to repair and eventually a class action lawsuit. I had previously taken the vehicle to the dealership to perform recall repair. They claimed this repair was completed, even though the defect still remained and caused engine to fail. The mechanic advised that a rod from engine was discharged, which "could have killed someone". The dealership initially approved an engine replacement due to known defect and class action lawsuit settlement, but then denied repair due to unrelated branded title. Hyundai corporate refuses to take responsibility for this defect, due to title status, that could have seriously injured or killed someone. One Hyundai agent advised during a phone call on 8/22/22 that Hyundai is not responsible for remedying any manufacturing defects if the vehicle has branded title, which is in contradiction to federal law. This is a grave safety concern and should be investigated by the NHTSA. I would be glad to participate in such an investigation, providing call records, names of witnesses, statements and documents as needed.

The contact's daughter owns a 2012 Hyundai Sonata Hybrid. The contact stated that while his daughter was driving at an undisclosed speed, the vehicle lost motive power with the hybrid system message displayed. The vehicle was towed to the dealer; however, no error codes were retrieved and the dealer was unable to duplicate the failure. The vehicle was then towed to Gray Epperson Hyundai (4100 APD 40, Cleveland, TN 37311) where it was diagnosed that the transmission needed to be replaced. The vehicle was last towed to an independent mechanic, who replaced the transmission; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to take the vehicle to the dealer. The failure mileage was 140,266.

My 2012 Hyundai Sonata, build date 10/31/2011, experienced the exact issue as described in NHTSA campaign number 15V759000. Note that the campaign covers Sonatas built before my vehicle's build date. The brake pedal stopper pad deteriorated and resulted in the brake lights falsely illuminating at random times. Furthermore, the condition - when occurring - resulted in the car overriding any throttle inputs, making for random inability to provide throttle inputs.

The contact owns a 2012 Hyundai Sonata. The contact stated that while driving approximately 45 MPH, the vehicle suddenly began to lose power and stalled. The contact was able to restart the vehicle and continued driving. However, the failure reoccurred while driving. The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The contact associated the failure to NHTSA Campaign Number: 15V759000 (Exterior Lighting). However, the VIN was not included. The manufacturer was not made aware of the failure. The approximate failure mileage was 84,300.

BRAKE LIGHTS KEEP EXPLODING

The contact owns a 2012 Hyundai Sonata. The contact stated while replacing the brake light bulb on the passenger’s side, the contact became aware that the brake light housing was melted, causing the bulb to be inoperable. The contact stated that the driver’s side brake light housing was also melted. The vehicle was taken to the dealer and the contact was informed that the VIN was not under recall. The contact was informed that the repair would be an out-of-pocket expense. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 190,000.

The contact owns a 2012 Hyundai Sonata. The contact stated while her daughter was driving 60 MPH, her daughter heard a knocking sound coming from the vehicle. The vehicle then lost motive power and stalled without warning. The vehicle was towed to the dealer where the oil was changed and the vehicle operated normally. The contact stated that the failure persisted. The vehicle was taken to the dealer where metal shavings were found in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle had experienced the failure listed in NHTSA Campaign Number: 15V568000 (Engine). The manufacturer was contacted and stated they were waiting on the dealer for the diagnostic result to proceed. The failure mileage was 92,000.

Check hybrid system keeps appearing on the dash, forcing me to have to pull over and stop the car. Dealer can’t fix it due to the code being intermittent.

"Hybrid system warning, stop safely and do not drive" and "check brake" alarm. Car immediately went into limp mode (15mph top speed). Luckily, I was not on the highway, but on residential street. Alarm was not recoverable by restarting car. Dealer says its the hydraulic brake booster and will cost $3250 to fix. Vehicle at 80,000 miles.

The contact owns a 2012 Hyundai Sonata Hybrid. The contact stated that once car has warmed up, while driving at low speed or starting to move after a stop, she vehicle hesitated and stalled while depressing the accelerator pedal. This is a serious risk hazard as the car barely moves at intersections where it is a risk of getting hit by incoming cars. There was no warning light illuminated. The contact had taken the vehicle to multiple independent mechanics as well as hyundai dealerships who were all unable to diagnose the failure due to no warning lights illuminating on the instrument panel and no codes getting registered in the ECU. The contact then got the car evaluated by another Hyundai dealership in order to exchange it for a new vehicle and mentioned this problem. This time the dealership mechanics claimed to have seen this same problem at several occasion and that the cause was failing electric motor (when warming up) which needs to be replaced along with transmission. They also said this failure would eventually lead to the car no longer being usable at all (catastrophic failure of drivetrain) The car was no longer under warranty and total repair cost around $11 000 CAN. This far exceeded the value of the car so the car could not be repaired nor re-sold. The failure pattern started to happen when mileage was approximately 110,000 miles

I was on the expressway and car hesitated and jerked while speed began to increase followed by hybrid warning system alert. (Pull over and stop the vehicle) with a flashing ready light. Could have caused a major accident with loss of life as there was no place to safely pull over. Warning lights came in immediately after the cat jerked.

The Air Bag sensor light will not turn off. several months ago I had brake light sensory issues that cost me $1,500.00 and now its the Air Bag light.

When arriving at a stop and then making a turn on a street vehicle came to a halt. It would not turn on again. The vehicle was able to be pushed to the side, and started to have a knocking sound from the engine, after vehicle was started . Searching thru the internet found recall campaign 312, that has same issues I experienced. Vehicle is drivable but has loud knocking sound as the speed goes up. Also, vehicle was purchased with a rebuilt title and is road worthiness.

I was making a Right turn when suddenly after making the turn my car shook and started slowing down by itself. The engine light, the oil light and the EPS and battery light all turned on. I was able to pull into a parking lot and the car just stopped. After trying to restart it, I noticed smoke under the hood. No prior warning lights came on.

I was on the highway during rush hour when the car was rattling during acceleration. I was going around 75mph. The car just died in the middle of traffic and I coasted to the berm. Once stopped, it smelled like something was burning and I had my 2 small children in the back in 5 point harnesses. They couldn't unbuckle themselves and I could not get the back door to unlock with the key fob to get into the back seat to help them. Once they were able to loosen their buckles, they had to crawl through the front seat to get out. Had the car actually caught on fire, I wouldn't have been able to get my children out in time. This was the absolute scariest ordeal I've ever been in. One shop has said the engine has seized. It's now sitting at Hyundai waiting for them to look at it. No warning lights came on until the car died.

2012 HYUNDAI SONATA. CONSUMER WRITES IN REGARD TO DEFECTIVE ENGINE. THE CONSUMER REQUESTED TO BE REIMBURSED FOR REPAIRS PERFORMED AT THE DEALERSHIP FOR ENGINE STALLING, KNOCKING, FAILURE, FIRE AND OTHER SHORT BLOCK ASSEMBLY REPAIR.

The brakes lights (all three) wont shut off even when the vehicle is not on.

AHB Hydraulic Break Module Failure car only has 60k miles.

The contact owns a 2012 Hyundai Sonata. The contact stated while his daughter was driving at an unknown speed, she heard an abnormal sound before the vehicle lost motive power. The contact stated that no warning lights were illuminated. The vehicle was not able to restart and was towed to an independent mechanic. The failure was diagnosed as a seized engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 15V568000 (Engine) however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The approximate failure mileage was 143,000.

I brought my engine in to be checked after the recall for engine failure. Hyundai told me it was fine/not affected. I brought my vehicle in twice after that because while driving, the engine suddenly stopped accelerating in the middle of driving. Both times, I was told that nothing was wrong with my car. They went so far as to accuse me of overfilling my gas tank (which I have never done). I trusted them instead of looking up this issue being part of the recall symptoms. Finally, while in the middle of driving, the engine locked up completely. I had it towed to Hyundai. They finally admitted it was covered under warranty, but I see no evidence of them recording it as a vehicle affected by recall. I am very concerned about this because there are probably thousands of other families at risk right now because of Hyundai's dishonesty and dodging responsibility and not including their VINs in the recall either. If their engines were to lock during a left turn for example, people are at risk of dying. In addition, Hyundai has still not reimbursed me for the towing and rental car costs of $2918.27 total which they are entitled to per the settlement. It has been over 3 months since I turned in the last of the paperwork. It has been over 7 months since the engine died. More importantly, they need to be fully investigated for withholding information, falsifying information, and putting people at risk of death and at a financial disadvantage.

Motor seized , powered off while driving down the highway at speeds of 55 miles of hour on a hill and would not start back , without warning other than a loud noise right before it shut off.

The contact owns a 2012 Hyundai Sonata. The contact stated while driving 35 MPH, the engine overheated. There was no warning light illuminated. The contact stated that there was smoke coming from the engine, and the vehicle was unable to restart. The vehicle was towed to the local independent mechanic who was unable to determine the cause of the failure. The vehicle was then towed to the dealer and was diagnosed with engine failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 67,000.

My 2012 HYUNDAI SONATA is experiencing knocking noises. I only have 125,674 miles on it. I have not received anything saying that the car has been recalled yet. I’m making monthly payments on this vehicle and needs to be fixed as soon as possible.

After recall repairs at Hyundai dealer in Danbury CT during the past few years, the engine light remains on or comes back on the next time the car is driven. Never had issue before these recall repairs. The car has been returned countless times to dealer to correct repairs and never successful. After multiple incidents of losing engine power and having to pull off highway i retuned to dealer again where they claimed fuel tank and fuel pump needed replacement for nearly $3,000 but never said if this was related to the ongoing recall repair issues or the engine coming on. I had another garage smoke test system and confirm gas tank didn’t need replacement. Error codes are related to recall parts in Hyundai TSBs for recall and other issues. Hyundai dealer and corporate HQ level consumer affairs remain unable or unwillingly ensure repairs are done correctly. All I want is the vehicle to be safe for family use.

There were no warnings or indicators of a problem. My husband was driving down the highway when he noticed smoke coming from under the hood. He pulled over, but the car was already on fire. The fire department put out the fire, and the car is likely to be totaled by insurance. The car is currently available for inspection but will be taken into possession by insurance soon.

My 2012 Hyundai Sonata is experiencing what caused Hyundai to recall 129k similar cars, but I never received a recall notice: https://www.caranddriver.com/news/a34874678/hyundai-engine-bearings-recall/#:~:text=Hyundai%20has%20issued%20a%20recall,and%20the%202015%E2%80%932016%20Veloster. My car is experiencing abnormal knocking noises from the engine, reduced power or hesitation, illumination of the "check engine" light and error code is coming across as "knock sensor"

The contact owns a 2012 Hyundai Sonata. The contact stated upon pulling out of a parking space, the oil pressure warning light and the check engine warning light illuminated. The contact parked the vehicle. The contact's husband test drove the vehicle and noticed that the vehicle went into limp mode and would only drive at slower speeds. The dealer was notified of the failure and informed the contact to take the vehicle in to their location. The vehicle failed to start. The vehicle was towed to the dealer where it was diagnosed that the engine was blown and needed to be replaced. The manufacturer was notified of the failure and informed the contact that assistance might be provided for the engine replacement. The contact was awaiting a call back from the manufacturer. The vehicle was not repaired. The failure mileage was approximately 118,000.

The knock sensor kept going off and check Engine light would be activated, we have taken to several auto places and check engine light and codes would be cleared, engine seized and no longer works we were stranded on side of road. Our understanding that this is part of the rod bearing inspection recall campaign. We purchased car for our daughter and it has a salvaged title, we were told by Hyundai dealer that due to it being a salvaged title they can't do anything. My understanding that any recall must be honored with or without salvaged title, is that correct?

What component or system failed or malfunctioned, and is it available for inspection upon request?: Vehicle went into LIMP mode on highway (June 7th 2022). The next day, the vehicle would not start, despite battery replacement. How was your safety or the safety of others put at risk? When in limp mode, car would not accelerate. My vehicle could have been hit by another vehicle due to the sudden, unexpected decline in speed; Has the problem been reproduced or confirmed by a dealer or independent service center? Vehicle was towed to the Hyundai dealership the evening of June 10, 2022. I was informed by Hyundai that it would take 2 to 3 weeks before they could even look at my vehicle. Vehicle has not been diagnosed yet. It is still at Hyundai as of today, June 22, 2022. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle is currently awaiting diagnosis by Hyundai. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The vehicle went into limp mode. The next day it would not start.

Connecting rod broke and punctured engine. Vehicle is available for inspection. My son was driving vehicle and the vehicle shut off while driving which could have been very catostrophic. Service center is who advised what the problem was after the vehicle was towed to their facility. Not inspected by any others at this point. Vehicle was just in for maintenance a week prior. No warning lamps or symptoms until the moment it happened. Approaching stop sign heard knocking or clicking noise, proceeded to side street to pull over and before he could pull over, the vehicle completely shut down. He went to look under hood and oil was splattered on top of hood and leaking all under vehicle. Vehicle was then towed to service facility who advised the connecting rod broke off and blew hole in engine.

I gave my son this car b/c I thought it was safe and reliable. My son was driving down the road and all of a sudden the lights started blinking and he pulled over. He had to have it towed and repair shop says the engine is locking up and would cost more to replace. This is a paid for car and now we are totally screwed. I really want the manufacturer to honor and fix their issues. I ensured I had this car serviced timely and took care of the car. Now, I am $12K in the whole and will probably go ahead and trade in my other 2017 Hyundai Sonata to avoid anymore of these issues that no one can honor to fix. This car has about 80K miles on it so not too bad, either!

About 1 month after I bought this vehicle, late December 2021, a warning light came on the hybrid screen, it read "Hybrid System Warning! Safely Stop And Do Not Drive!" The accelerator was not working I pulled over and turned the vehicle off. I waited a couple minutes and restarted it up again and went on my merry way. About a month later it happened again!! It's happened about every 5 weeks until June 16th at about 5pm, it now permanently chimes and beeps with the Hybrid screen warning me of the same, my foot brake goes to the bottom and makes a grinding noise. I am not able to drive it more than 100 yards or so then the accelerator fails again. I owned a mechanic shop and I know my brakes are fine, there has to be something wrong with the brake pumps/master cylinder, the brake fluid reservoir is full and the brakes electrical components make a horrible noise when I depress the foot pedal, I've read on Hyundai Forum on-line, that this has happened to various others, its happened on the freeway while I was going about 70mph!! It's happened on busy city streets with 45mph speed limits. Hyundai doesn't want to take any responsibility for it! What can I do? The dealer wants $200 to have it checked with no guarantee that they'll find the problem. Thank you [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Tail light sockets overheats causing bulb to become stuck and whole tail light assembly needs replacement
