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 wear. Although my vehicle does not currently exhibit any visible oil leaks, the oil consumption issue suggests underlying damage that could potentially lead to engine failure. Considering the potential risks and the known issues with the Theta II engine, I kindly request that my vehicle be inspected and, if necessary, repaired under the terms of Recall Campaign 162. I urge you to address this matter promptly to ensure the safety and reliability of my vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
2014 Hyundai Sonata engine complaints
Page 3 of 12: complaints 41 to 70 of 322, newest first, as owners wrote them.
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 from both the dealership and the company an have received no assistance in reclaiming confidence in the vehicle or Hyundai as a whole. This happened in September 2024 and there is no resolution in sight here in December. How a customer can be expected to repair at their own cost during a known recall with a class action lawsuit is ludicrous.
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 the residence. The contact used an OBD machine to diagnose the vehicle and retrieved fault codes for an oil pressure failure which caused the engine failure. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 120,326.

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.

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 vehicles are dangerous to the public and have a known engine defect that because of this the manufacturer has implemented a software patch known as KSDS and with this recall in place should have allowed my daughter to reach a safer place than being stranding on the side of a busy hi-way. My car had this patch installed and I was assured that this recall would allow the car to be driven a safe distance and it would be obvious when this patch was active and the engine would be put in "Limp mode" This did not happen, the engine locked up
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 there is a recall on the car for the safety plug and that was replaced. I was also told I needed a new battery and new power relay assembly. Those parts are related to the safety plug and the operation of the charging system. Why are those parts not also part of the recall? The dealership charges a diagnostic fee when they already know what the issue is. Must be nice. Everyone involved is building their own karma. I'm very displeased with this Brand. I will never buy another one and I will tell everyone I know hyundai does not stand by their product in making sure it's safe and operational. And they leave the consumer stuck with a bill that was their fault. FYI I had a prior complaint case with consumer affairs. (The mileage I stated was when it first happened. Now it's at 90k)

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 (the federal safety agency 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 for diagnostic fee again and additional repairs again. So far, the repair costs exceed $3,000. The car displays show that it is one notch from overheating, runs a little sluggish, knocking noise at times and are experiencing similar issues when prior to when the engine was replaced initially back in May 2022. I am afraid of the car seizing up while I'm driving potentially causing an accident or fire as several consumers have noted the same. I have corresponded with Hyundai Corporate on several occasions asking for assistance as I quite frankly do not feel safe Hyundai or Kia vehicles. I had also asked for some type of assistance with my repair costs again that I feel are engine related otherwise why else would the check ENGINE light be displayed. In all instances Hyundai Corporate has simply skirted the greater issue and provided me with a staged response. Now I’m being told that possibly the injectors need to be replaced on a car whose engine was replaced less than 2 years ago. I’ve asked Hyundai several times to replace the car in like kind and quality because they are allowing a car to be unsafe to be operating .
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 engine was recalled it created issues with other parts such as oxygen sensors, catalytic converter , etc to fail and by not taking fiscal responsibility has created a safety issue for millions of Americans. I am begging the federal safety agency at demanding Hyundai replace the vehicle and /or reimburse for additional expenses mentioned above as I am not the only American having to deal with Hyundai’s negligence. Simply saying it is not part of the warranty is not an inclusive defensive when millions of American lives are at stake.
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 contacted Hyundai of Slidell and they said since these open safety recalls have not been addressed that they will just reject them. There are about 2 from before I even bought the car that were issued in 2017 I believe that have not been completed. I bought the car in October of 2021 and was not informed of these safety recalls. Prior to this incident, no warning service lights had appeared and I was never told that I need to get my engine inspected as it ran fine.
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.
With the 2014 Hyundai Sonata GLS off and onto a tow truck, it spontaneously burst into flames and the eventual total loss of the vehicle. The 2014 Hyundai Sonata GLS need to be added to the notice to Hyundai consumers in the Hyundai 251 recall.
The car warning lights turn on and the car shuts down. The problem is with the Hybrid battery that is malfunctioning. This is a serious life and death problem. After the vehicle stops it goes in neutral and rolls .
UNKNOWN: my wife took the car to go to the store by our apartment. She was going through a roundabout at 10 maybe 7 mph when the car just shut off. We took it to AAA. AAA told us that it was an engine failure, and that there was an engine recall on our vehicle. We still thought it was the Ater. We took it to a shop called Gulich. They saw the engine factory recall and informed Chapman Hyundai in Scottsdale to repair the vehicle. Spoke with a Nick who told us that he would give us a free loaner as they fix our vehicle, and that it was under the recall. Got a call two days later from Nick stating that there was sludge in the car and it was from the previous owner, that is why they’re not fixing it. The previous owner only had the car for two years as we receive the car in 2016 with 36,000 miles on it. Every oil change, tuneup, air conditioning, etc., we were told that the car was a queen puff, and that there should be nothing wrong with it. This is just an unfortunate misunderstanding, I would like to have my car fixed they are pressing me to return the loaner and my wife is in the hospital. Trying to leave me stranded. Please help .
