2014 HYUNDAI SONATA Engine Problems

I had recall 162 - engine replacement completed in 2024 , now I have fuel leak at high pressure fuel pump, the pump that is a component of the engine has now failed which was installed during the engine replacement which can cause a major fire

While driving with my family on a busy freeway at approximately 70 mph, our vehicle suddenly displayed a loud, urgent warning: “Hybrid System Warning – Safely Stop and Do Not Drive!” At the same moment, the car lost the ability to accelerate without any prior signs of trouble. We were extremely fortunate to have enough momentum to coast to the shoulder and shut the vehicle off, unsure of how serious the issue might be. Being stranded without warning on a high‑speed highway put my entire family in a dangerous situation. After a few minutes, we restarted the car to see if we could at least get it off the freeway. The warning had disappeared, and the vehicle drove normally, allowing us to take back roads home. The lack of any prior symptoms makes this even more concerning. Losing acceleration at highway speeds with no warning is a major safety hazard....

The engine failed in my 2014 Hyundai Sonata for the 2nd time while driving in evening traffic on a major interstate with my elderly father in the car with me. The engine completely shut down while in mid drive on the interstate with no power. The engine and oil lamp indicators immediately came on right before the engine lost power on the interstate. This caused my safety and the safety of my father to be put at risk by not being able to have any power while in the lane of evening traffic. My vehicle was towed to the nearby Hyundai dealership, Modern Hyundai of Concord, where their service department conducted inspection of the engine issue and where it was kept for 4 months with no repairs made per the orders of Hyundai Motor America. Hyundai Motor America refused to honor their own warranty to replace the engine (engine in...

The vehicle experienced a sudden engine failure and loss of power while traveling at freeway speed. Two days earlier, the vehicle had been taken to an authorized dealership for factory recall service. During that visit, concerns were raised about known engine issues associated with this model, but the vehicle was returned to service. While driving on the freeway, the engine abruptly stalled without warning, causing immediate loss of propulsion and power. This created a dangerous situation in moving traffic, requiring rapid maneuvering to avoid a collision and safely exit traffic lanes. The vehicle became inoperable and could not be restarted. The failed component appears to be the engine or related internal engine system. The vehicle was towed back to the dealership following the incident and has remained inoperable since that time. The vehicle is currently available for inspection. The failure placed the driver at significant risk due to the sudden...

My 2014 Hyundai Sonata experienced a P1326 engine fault code, which activates the knock sensor system due to engine bearing wear. This condition is directly related to Hyundai’s safety recall 17V226 (Theta II engine). The Hyundai dealership submitted my case to Hyundai corporate, and Hyundai denied the repair solely because my vehicle has over 150,000 miles. A manufacturer cannot refuse a federal recall repair due to mileage, and Hyundai’s engine recall has no mileage or time limit. The denial places me in an unsafe situation, as the recall defect can cause engine seizure or stalling while driving. I am requesting NHTSA intervention.

This motor had a recall. Campaign t3g- sonata yfa 2.4L Theta II. 1 month after an oil change at the mechanic the car started making noises. Took it right to the mechanic who said there was no oil and that there was a recall on this motor for this reason. Immediately took it to the Hyundai dealership located in centereach NY. The employee who helped us was not a help. Took days and days to even get the paperwork In for the recall. Did not communicate with us unless we called him. Then eventually just said it was denied. Took weeks to get the proof from them. Completely frustrating. We submitted all proof of oil changes and maintenance and it was denied saying engine neglect! We are struggling to keep up with bills and now cannot get to work because of this. We have 2 toddlers and he is a...

CAR MAKING LOUD NOISE UNDER THE CAR HOOD LIKE SOMETHING FALLING APART UNDER THE HOOD, A MECHANIC TOLD ME THAT IT WAS THE ENGINE , I WAS ALSO TOLD THAT THERE WAS A RECALL ON THIS CAR ENGINE. HYUNDAI DID MY 90,000 MILE INSPECTION ON JULY 19, 2025, AT THE TIME THE WORK WAS DONE I ONLY HAD 87238.

Hello, I brought my 2014 Hyundai Sonata (approx. 73,000 miles) to an authorized Hyundai dealership (MotorWorld Hyundai, Wilkes-Barre, PA) on August 4, 2025, for Recall 162 (NHTSA 17V-226) due to audible engine knocking. I reported the noise when dropping off the vehicle. The dealer claimed the engine passed the inspection but did not provide any documentation confirming that the required bearing test was performed. They said the issue might be from the top of the engine (possibly the timing chain) and wanted to charge $800 to disassemble the engine, with a repair estimate of $2,900. The reason they wanted to disassemble the engine is because after an initial diagnosis for $160 they discovered the noise is not from the timing chain. Besides, it would be extremely unusual for the issue to be a timing chain at 73k. I later learned from Hyundai Customer Care that the recall still shows as...

My engine has a knock and the dealership told me that they would not fix it due to "lack of maintanence" but I tried explaining to them that I was unable to get proof because Oreily and auto zone were unable to get me receipts on old purchases.

Engine Failure. After taking my Hyundai listed above in for repairs to the air conditioning not working properly and while in custody of Jeff's Automotive Service, here in Sterling, IL 61081, the engine suddenly died out while they were test driving the car. They were able to jump start it once, and then it died out again while driving it. This time the car could not be restarted by all means possible. Being in the shop, other possible causes were checked and not one of them worked. The Engine is completely DEAD. After Checking for possible causes online it was found that a recall for the very same Engine Failure had been done back in 2017/2018.\n" + 'For unknown reasons, I was never notified nor did I ever received such notice. Now at this time, we have contacted a local dealer and they state that because the auto had not...

The vehicle experienced engine stalling and rough running. We discovered it had an open engine recall related to known defects in the Theta II engine. We dropped the vehicle off at a Hyundai dealership (Hyundai Napleton) on July 1st, 2025 for recall repair, following instructions from ACV Auctions. After holding the vehicle for over three weeks, Hyundai Napleton informed us they could not perform the recall due to their internal policy against working on dealer-owned vehicles. This directly contradicts the purpose of a federally mandated safety recall, which is supposed to apply regardless of ownership. On July 23, 2025, we received a call from Hyundai Motor America, stating they would not approve the recall repair because the vehicle had been declared a total loss. This is entirely false—the vehicle has never been declared a total loss by any insurance company or official source. It appears Hyundai Motor America and the...

My engine seized and I lost power. This is the second engine this has happened to. I was given a extended warranty, but Hyundai is refusing to pay for a new engine. The mechanic advised me they are replacing engines three times a week. Mine was denied even though my engine only has 76,000 miles and my warranty is still good. This engine problem should be a new recall since the same problem is still occurring. The engine light did come on blinking. When I took it to the dealer. They knew the problem before looking at my engine since so many others need to have thiers replaced. The dealership confirmed i need a new engine. They made me send in my oil changes. They were upset I didn't have any oil receipts for my previous engine even thought it was replaced at a Hyundai dealership the first time. Consumers...

Dear Sir/Madam, I am writing to file a formal safety complaint regarding a dangerous incident involving my Hyundai Sonata Hybrid (VIN: [XXX] ) and Hyundai Motor America’s failure to fully correct the issue. Incident Summary: While driving on the freeway, the vehicle suddenly displayed the following alarming warnings: “Hybrid System Warning! Safely Stop and Do Not Drive” “Check Charging System” Immediately after these messages appeared, the car lost all power and shut down in the middle of the road. I had my two young children (ages XXX and XXX) in the car, making the situation extremely unsafe and traumatic. The vehicle lost all mobility and provided no opportunity to safely pull over. After contacting Hyundai Corporate multiple times, a case manager was eventually assigned to my case. At Hyundai’s request, I towed the vehicle to AutoNation Hyundai Valencia for diagnostic evaluation. The dealership diagnosed the issue as error code P0A78,...

Engine light is blinking and put safety of my family in danger. I called the close Huyndai dealer also I have a case number. However, it takes forever for them to answer. I only have this car. I am driver and this how I make living. I have no choice in driving this recall vehicle and kill my self and my family. No body care!

When I was trying to accelerate, my gas pedal just wasn't responding at all and the engine, oil, and battery light all came on. When that happened my car shut down and I coasted to a stop.

While driving my 2014 Hyundai Sonata on [XXX], the engine suddenly stalled without warning. I was in motion on a public road when the vehicle lost power, forcing me to safely pull over. There were no warning lights, check engine lights, or prior signs of engine trouble before the failure occurred. I had the vehicle towed to a certified Hyundai dealership (Norm Reeves Hyundai Superstore in Cerritos), where I was told the engine failed due to rod bearing failure caused by oil starvation. The dealership stated that the engine needed to be replaced. However, I have maintained the vehicle regularly, with consistent oil changes and maintenance, and I have documentation to prove this. Despite this, Hyundai has refused assistance and claims "exceptional maintenance neglect" without showing inspection photos or detailed evidence. This engine failure fits the exact pattern of a known engine defect already under recall for similar Hyundai models...

While driving on the highway, the engine of my 2014 Hyundai Sonata suddenly seized without any prior warning. There were no preceding symptoms such as warning lights, unusual noises, or performance issues that might have indicated an impending failure. At the time of the engine seizure, I also lost power steering and power brakes, which severely compromised my ability to control the vehicle and led to a dangerous situation in fast-moving traffic. I later discovered that vehicles equipped with the Theta II engine have experienced similar issues, suggesting a potential safety-related defect. I am reporting this incident as a serious safety concern and request that NHTSA investigate this matter further.

Car transmission replaced with only 38,000 miles. Car shutters, skip gears, loss of power. Very dangerous especially when pulling out from side road on to main road. Transmission problem starts out as intermittent at first, so you never know when it will happen next. Lots of near misses where I would have been rear ended, due to shifting problems. New Transmission is already starting to shift erratically at times with only 2,000 miles on new rebuilt trans. Cost of repair is 5 to 6,000. Also own 2012 Hyundai Sonata Hybrid with the same exact transmission problems. Transmission replaced at 67,000 and now at repair shop for replacement Trans at 124,000 miles. Vin [XXX] . Both of these cars are dangerous to drive. These problems start out intermittently, and if the dealership cannot duplicate the problem, they will not fix anything, hoping to string you along past the warranty period. I...

Misfiring cylinder

Just purchased the sedan and took it to a shop to get checked Reason for the doing was because vehicle felt a lil rough after getting the vehicle checked they came to the conclusion that the motor had seized

Due to a recall Hyundai promised a lifetime extended warranty on the engine of my 2014 Hyundai Sonata concerning a defect in the engine manufacturing. We're as metal shavings can cause rod bearings to wear out causing what is known as engine knocking noise. Well my engine is knocking, and I was told by a license certified mechanic that it's my rod bearings & that the engine is fixing to throw a rod. This is covered under the extended lifetime warranty. When I called Hyundai they said we aren't going to fix the issue because the vehicle has a salvaged title. I had a consumer rear ended me years ago, there insurance company totaled out my car which was not totaled. Only minor rear damage. I ended up keeping the car and it drove fine, no engine damage due to the wreck on rear end damage. This shouldn't stop my...

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated, and the vehicle went into LIMP Mode. The vehicle was taken to the dealer, who retrieved DTC code P1326 for the knock sensor detection system (KSDS). The dealer performed a software update, but the failure persisted. The vehicle was taken back to the dealer for an oil consumption test, which the vehicle failed. The contact had an independent mechanic replace the knock sensor and spark plugs; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 62,000.

While driving down the road the car died. Now it will not start.

I got a 2014 Hyundai Sonata in May of 2023. In the beginning of September 2024, I was driving down the road on a highway and a knocking sound began as well as grinding. The car then immediately lost all power which could’ve resulted in a serious accident like death or injury to me or others. I found out about the engine recall right after for the class action lawsuit for Hyundai. They told me I was good under the extended warranty. I was told that I needed to get the odometer branding fixed on the title before they would honor the recall. I did that and received the clean title in the beginning of November. The car was at a garage where they agreed that the car had premature worn engine bearings and had failed. The car went to a dealership in the beginning of November. Then I was...

The contact owns a 2014 Hyundai Sonata. The contact stated while driving at an undisclosed speed, there was an abnormal knocking sound coming from the engine compartment. The contact stated that the sound was persistent. The vehicle was driven to a local restaurant parking lot. The contact stated that the vehicle had stalled several times.

There was no warning, engine seized on main Hwy at night driving approximately 45mph. Couldn’t even pull off to the side. My child and I were stuck on a main road with no warning anything was wrong. Car stopped driving completely. This was my forth engine. Hyundai has always replaced it. 4 in 27k miles. This time they denied it.

To Whom It May Concern, I am writing to express my concern regarding my 2014 Hyundai Sonata, Vehicle Identification Number (VIN): [XXX] , which is currently experiencing excessive oil consumption. I have recently become aware of Recall Campaign 162, which addresses a manufacturing defect that can lead to premature engine wear and related issues. Despite regular maintenance and proper care, my vehicle consumes an abnormal amount of oil, causing me to frequently top off the oil between oil changes. This not only increases my maintenance costs but also raises serious concerns about the safety and reliability of my vehicle. **A trusted service provider has confirmed that the oil consumption in my vehicle is abnormal and is likely related to the defects outlined in Recall Campaign 162.** As stated in the recall, the machining errors during the engine manufacturing process can restrict oil flow to the bearings, leading to premature bearing...

I was driving the car to take to emissions because the car was recently purchased and as I was driving the car turned off and doesn’t turn back on.

The vehicle suddenly spiked in RPMs, and suffered from a rattling noise. The following day after taking it to a known skilled service location, they advised to contact the dealership due to two open recalls. They found zero oil in the vehicle as well as issues with the valve seals. They then put the blame on the customer and did not acknowledge the engine recall that states clear problems with oil and engine valves resulting in a loss of oil and a failure in monitoring systems. At no time did the oil light show on the dash and there was no oil in the driveway where the vehicle has been parked. They advised us to contact the company for assistance. After doing so, the dealership, and Hyundai themselves have refused to acknowledge the engine issues or repair the car under the two known open recalls. We have spoke with reps...

Oct 24th, 2024 on highway had accelerated to 75, all of a sudden, car experienced mechanical shutdown, engine light came on would go fast slow down, felt like braking down, engine light was solid, had to get very slowly somehow into the brake down lane. Turned the car off, waited long time...got advice to try to power car back on because was night and was dangerous lane. Car started, drove very slowly home with hazard lights on. Next incident (that I was on hgwy) Nov 24th, 2024 went from 65 to work up to 80MPh, the car lights went on for engine, slowing down,no control of the speed, no accelerating, lights, made to pull over...turn car off...waiting 15 minutes, drove in break down lane, was only 7-8 minutes from my house off highway.

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving approximately 70 MPH, the vehicle suddenly lost power and the contact was able to coast to the side of the road. The instrument panel was illuminated with several unknown warning lights. The contact restarted the vehicle and continued driving. Three months later, on November 11th, 2024, while driving approximately 40 - 45 MPH, the check engine warning light illuminated with a message indicating a failure with the Variable Valve Timing Solenoid. An independent mechanic confirmed that the Variable Valve Timing Solenoid was the cause of the failure, and the contact replaced the part himself. The following day after being idle at a stop light, the contact attempted to accelerate, and the vehicle failed to accelerate. The vehicle was restarted; however, there was a knocking sound coming from the engine compartment. The contact had the vehicle towed to...

I was driving at a higher rate of speed 50 MPH in the center of 3 laned road no warning or indicator lights were on in my vehicle when the engine without warning blew and stopped working. Again no check engine lights were on no warnings were given. It shut down and would no longer accelerate or drive. We almost caused several accidents as this was a very busy roadway.

Extremely rough idle when stopped. Trying to accelerate to merge into traffic the my. Car had no power and I almost got creamed ! I had to pull over so other cars could go around me. Several other issues with car like oil every month or so. I had gas pouring from a hose on my engine and when I brought it to dealership they wanted 1100.00 knowing it was a recall. I hope the dealership and Hyundai rot. !

Stopped at a stop light, started going again, got up to about 20 mph and engine stalled on the side of the road. Had to wait HOURS for a tow, triple A couldn’t help, had to pay $70 out of pocket. Now they are denying me for an engine replacement, each time I submit the documentation they request, they find some reason to turn it down, and when I ask what they specifically needed me to do, they just gave me a phone number to call for Hyundai customer affairs, even though I have already gone through all of this with them, and they directed me back to the dealership as far as communication goes. I’m getting the run around, and it has been going on since May.

Car stalled at 65 mph and went in to limp mode. Knocking noise came from under right side of engine. Car is not drivable at this time. Sounds like a rod thrown and there are metal shaving in oil.

The contact owns a 2014 Hyundai Sonata. The contact stated while driving approximately 65 MPH, the vehicle lost motive power and stalled. There were no warning lights illuminated. The vehicle was not able to be restarted and the vehicle was towed to an independent mechanic where it was diagnosed with engine failure. The vehicle remained at the independent mechanic and was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

Engine stopped running while driving. Taken to Hyundai for theta ii settlement. Claim denied due to exception negligence. Discoloration found on cam. Car burned 1 quart of oil every week or two which confirmed with independent mechanic can cause discoloration. Claim denied without cause.

Hyundai Motors fails to sympathize with their customers. I bought a Hyundai Sonata 2014 which caught a fire on October 9th 2019. Hyundai finally conversated me for the car in how much it was worth $4,150.60 on March 20th 2024 and not for punitive damages. I feel they are very unfair and I need my punitive damages I lost a lot not only a car but my job as well. My livelihood and transportation on top of that. And I need help to recover my punitive damages.

On Feb 15th 2023 my daughter was driving my 2014 Hyundai Sonata at the posted speed limit of 55 MPH on a 2 lane blacktop when the car suddenly and without any warning at all, lost all power and became unresponsive while traveling with other vehicles behind her, in front of her and in the opposing lane of travel. Without enough of an improved shoulder to pull to the right and a steep embankment on that side of the roadway as well, she was forced to veer to the left with other cars approaching. She had minimal braking, steering and no response to depressing the accelerator pedal at all. She was able to direct the car onto a paved portion of a feeder road and finally got the car stopped. The cabin filled with smoke and there was smoke all around the car but no fire was ever found. These...

This is the 3rd time in 2 years my car shuts down while driving. The dash panel started flashing "WARNING CHECK CHARGING SYSTEM. DO NOT DRIVE" and an alert starts beeping and the car shuts off. THERE WAS NO OTHER PRIOR WARNING LEADING UP TO THIS. Why isn't there any warning BEFORE it gets to this? This is an accident waiting to happen. Do you know how many accidents would happen if every car just shut off like that because of some faulty charging system. Any other car would have warned you before hand. It's by the grace of God I was not slammed into while crossing a busy street and this damn car shut off leaving me right in harms way with cross traffic. AND another time it shut off on a busy highway. COMPLETELY DEAD. No functioning hazards. It's not right. This last time, The dealership told me...

The contact owns a 2014 Hyundai Sonata. The contact stated that while at an intersection, the vehicle stalled. There was smoke coming from the engine compartment. The contact stated that several unknown warning lights were illuminated after the failure. The vehicle was towed to a tow lot, and the contact was informed that the failure was because the engine had seized. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 89,814.

This car burns oil at the rate of a quart every 300 miles.I have had it at the dealer several times and Hyundai has been no help at all. Their final recommendation was to replace the engine and I would have to pay for this repair.

Engine was loosing power and know dosent start at all

I am filing a complaint due to the lack of timely fix of this recall. It has been more than four months since the recall was issued (NHTSA Recall Number 23V651000) with no repair available.

I have a 2014 Hyundai Sonata that had its engine replaced as part of the recall. The car was taken to Hyundai of Central FL in January 2022 and repairs were completed in May 2022. Since that time the car has had several repairs that I feel are a cause of the faulty engine and or engine related to the replacement. These repairs include oxygen sensors both front and rear replaced, additional sensors, catalytic converter, transmission flush. Just in this month the car has been taken to Greenway Hyundai in Orlando weekly for a check engine light. The car was taken last week after the check engine light came on again and oxygen sensors needed to be replaced again. After the car was picked up last Wed, the check engine light on again and is currently sitting at Greenway Hyundai in Orlando for additional diagnostics. I may have to pay...

Engine started making a weird knocking noise & was smoking from oil lid. Was driving & the noise got louder & then started to making a squealing noise. Started heading towards the dealership & it slowly started loosing power. Got to the turning lane to turn into the dealership parking lot, car immediately died in middle of road causing me to almost be hit by another vehicle . It started up long enough for me to make it into the parking lot. Car is now currently sitting at dealership waiting till Monday for Hyundai Service center to look at it. I originally had an appt scheduled for Tuesday to get it looked at but it didn’t last that long. speed limit was 35, I couldn’t even drive over 20 mph & had my emergency hazards on.

In May 2022 the engine was replaced as part of the Theta engine recall. Since that time the vehicle has been taken back to the authorized Hyundai dealership for oxygen sensors and a catalytic converter to be replaced. The check engine light is still on and out of pocket expenses are in excess of $3000 and growing. Hyundai corporate is refusing to cover any of these expenses stating that it is not engine related. In the meantime the car check engine is still on and by not taking responsibility for this has caused a safety issues as it is a known fact that their cars have a history of catching fire and I’m fearful that this may occur unless Hyundai takes responsibility and reimburses for these repairs and/or replace the car with one in like,kind and quality. It is my firm belief that Hyundai is well aware that when the...

As I was driving on the interstate, 25 or so miles away from, my car started to shake and the service lights appeared on the dashboard. I pulled to the shoulder of the road, and shut it off, i turned it back on and it ran for maybe about 10 more miles until it happened again. This time, I turn it back on to get it to run and it doesn’t even begin to shift into drive. It started making a grinding/knocking noise from the engine & shaking, so I shut it off. I had to get it towed home and it has just been sitting in the drive way for a couple weeks now because it’s undrivable. I had no knowledge prior to this incident of an engine recall issued on the car, the dealer I bought it from didn’t inform me and neither did my lien holder. I...

My engine is burning through oil and also smoking while driving and has a burn smell coming through air vent. I scheduled to have it repaired and have a screenshot of the recall but when I took it to get repaired they stated there are no recalls on my vehicle and I would have to pay. I then called Hyundai customer service and was told they see the recall in one system but not the other and that they will give me a call back. I then never received a call back so I called again and was told that they cannot fix the engine recall and that I would need to get a diagnostic and pay for it myself.
