2015 HYUNDAI SONATA Engine Problems

While driving our vehicle (Hyundai 2015 Sonata Hybrid) around 25 MPH speed in city road... the vehicle stopped completely by itself in few seconds. Got the message "Hybrid System Warning! Safely Stop and Do not Drive" in dashboard and beep beep sounds. Thank god, no accident, the vehicles behand able to stop and avoid the collision. This is serious SAFETY issue, as this could cause accidents if vehicle stops by itself while driving. This is 3rd time in last few years with this vehicles. The recent incident happened was on 5/1/2024 morning around 8.00 am. We went to the Hyundai Service Center and they did looked at the codes and ran some scans and they found nothing wrong. And they said it could be some wrong system warning and can be ignored, as they can't reproduce the issue. And told us to report if this happens, but the worry is...

My Sonata is experiencing Engine failure due to excessive and irregular oil consumption. The Hyundai dealership conducted an oil consumption test in which it was discovered that the car is excessively using oil. My Safety and the safety of others were put at risk as the engine slow and stalls without prior warning and the check engine light does not come on until the vehicle slows and stalls. The vehicle was inspected at a Hyundai dealership and submitted to Hyundai for all or partial financial assistance for a new Engine and in turn was declined by Hyundai even though they have a know issue of their Engines consuming an unusually high rate of oil.

The check engine light began flashing so I shut the car off and had it towed to West Allis Hyundai. The service garage took the car for a test drive (even though the user manual states not to run the engine), and according to the dealer, the car engine "blew up" and stopped running. I assume the engine seized up. the engine only has 43,000 miles and should be covered by the 100,000, 10 year warranty that comes from the manufacturer. The car has been at the dealer for over a week without any definitive answer if the engine will be replaced by Hyundai under warranty. Also, the dealer has not provided a loaner car so I am without any transportation while my is in the shop. Note that since I've had the car all maintenance has been done by West Allis Hyundai.

In December, 2019 I purchased a 2015 Hyundai Sonata for my son that had around 32K miles. Maintenance records looked good, and I continued to keep up with the maintenance on this vehicle. Around 64K miles, I was notified after an oil change the vehicle was low on oil and a gasket needed replaced. I took the Sonata to another place to get the oil changed and for a 2nd opinion. The conclusion of the 2nd opinion was there was internal pressure causing excessive blow by. That even if I replaced the valve cover gasket, the pressure would build up. Ultimately, we determined the vehicle is consuming/burning oil. Columbia Hyundai said there wasn’t anything they could do because my vehicle was out of warranty. My issue was and continues to be Hyundai will not do anything about the oil consumption issue. I am being told the engine will fail and...

I had my engine replaced less than 5000 miles ago and now my check engine light is on once again causing more problems and Hyundai is very unwilling to do anything

Car repeatedly illuminates check engine light since my purchase on 9/30/2023. When this happens the car goes into limp mode, fails to accelarate and at times stalls. This has happened on the freeway and at busy intersections while driving.

Check engine light illuminates repeatedly causing the car to go into limp mode (max speed of 30) & at times it stalls while driving. I purchased it on 9/30/23 & check engine warning light has illuminated 20+ since then. I’ve repaired and addressed all of the codes. It also occasionally accelerates abruptly when stopped causing the car in front of me to be hit from behind. In addition to all of the above safety issues, it also has an extremely high oil consumption rate. The engine is faulty and needs to be replaced.

The contact owns a 2015 Hyundai Sonata. The contact stated that while the vehicle was idling at a stop light, the vehicle lost motive power and stalled. The vehicle failed to restart. The vehicle was towed to the local dealer to be diagnosed. The contact was informed that the engine was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer and local dealer were not yet notified of the failure. The failure mileage was 170,000.

The contact owns a 2015 Hyundai Sonata. The contact stated that while accelerating to 60 MPH, the vehicle stopped. Several warning lights were illuminated. The vehicle was towed to a local mechanic and a diagnostic test was performed. The mechanic completed a tune-up, and changed the oil, and the brakes however, the failure persisted. The mechanic informed the contact that the engine needed to be replaced and the vehicle was towed to the residence. The vehicle was not repaired due to the cost. The manufacturer was not made aware of the failure. The failure mileage was unknown.

Knocking noise in the engine, super loud sound, engine sized up because there was a lubrication failure from the oil pump, rock arm bearing was gone on cylinder 3 crankshaft catastrophic damage, and tulsa hyundai send an application to hyundai USA and they refuse to fix my car because the previous owner didn't do 4 recalls that are not even close to be related to the problem in the engine. Abs light recall, seat belt recall, parking brake light switch recall and smart junction box recall, none of this has anything to do with the negligent fabrication on rotating parts in the oil pump, and rock arm bearings, this is very upsetting and disappointing that a recognized brand like hiunday did such a big mistake in fabrication and they found the perfect stupid excuse to wave their responsibility to the customers that invest their money on this cars

I am the only owner of a 2015 Hyundai Sonata: in December 2018 the car had a new engine put in when the mileage was 106,894 due to the engine burning oil much too fast. On 9/20/2023 while getting an oil change Jiffy Lube told me the oil was almost empty, as the engine was burning oil way too fast again. This was at mileage 162,148. I checked the oil periodically to make sure the engine had oil. I added a quart around 163k and on Feb 3, 2024 I checked the oil at 165,000# miles on it barely had any oil in. I filled with about four quarts and then I started the car. Upon starting there was an explosion in the engine and all the oil drained out. My complaint is Hyundai replaced a know defective engine with the same defective engine, which unknowingly to me but me...

Car was going approximately 50 miles an hour on a side street when warning lights went on, brakes stopped working, and the engine smoked and appeared to catch on fire. Car was steered into a parking lot and abruptly placed in park. Occupant grabbed valuables and quickly exited the vehicle. At that point, the front of the vehicle, under the hood went up in flames.

The same as all other Hyundai I’ve seen from 2011 to 2019. Error code reads P1326 manufacturer control. the vehicle shut off on me 65 on the highway without warning. hook up the car to the computer and it has returned no code so we troubleshoot by that the starter was burnt up and we replace it everything‘s fine for two days. Then of course I get the manufacturer code P1326 and find out that 100s are not thousands of Hyundai have been recalled for the same issue. Also, like all other complaints, I’ve seen car went into limp mode or reduced power mode and the check engine light is flashing

Engine has an oil consumption issue.

About 20000 miles ago, I was informed by my servicing center that my Sonata came it without oil on the dipstick. My car currently has 90k and my engine is burning about 1qt of oil every 1000 miles. Many people have been having issues with these engines from Hyundai and Kia. My engine has been a part of a class action lawsuit regarding this problem but my specific model is never included even though the engine is. I've been checking my oil regularly and keep oil in my trunk at all time since this first happened but I'm getting close to my car being out of warranty. When I get my oil regularly changed at 3k - 4k miles, well below the the suggested 6k, is it my responsibility to add oil all the time or is it the responsibility of Hyundai to replace my engine for being faulty? My...

Car has a distinct burning smell when driving it. This has been going on since late summer of 2023. I moved to a different state from NC to AL. Had it inspected and because it wasn’t smelling at the time the mechanic stated there were no issues. Also, got a recall for campaign 993 with my vin number from Hyundai and no dealership will honor it bc when they look up the vin it says no recall due. Please help me rectify this situation so I’m not out of a car. I don’t know if it’s bc I relocated that I’m not getting cooperation. I’m not able to even schedule an appt with the dealership bc of this. Please help.

The car has been having problems with oil consumption. The problem became known in 2022, but the dealer/service department (Frank Hyundai, National City, CA 91950) did not take care of the issue and did not care about safety. The dealer told me, "Your car is OK." On 7/3/2023, the engine light came on. A second round of oil consumption tests began along with a 90,000-mile service, including replacements of filter assy and gasket, four new tires and front and rear brakes, spark plugs, suspension/steering repair, shaft assy, engine repair, cooling system service, and fuel induction service. Shortly after, the car slows down even when my foot is on the accelerator. It feels as though the vehicle will stop. I can see the rpm gauge erratically going up and down. The car lurches or jerks. I reported the jerky problem to the dealer at the second 1000-mi oil consumption test, but...

My break went out while trying to make a stop.

In the first incident(2020) after the check engine light was on, the car was towed and needed the valve cover and fuel pump gasket replaced due to leakage. In November of 2023, the check engine light kept flashing and again the car was towed to the dealer. The valve cover was removed and we were told a new engine was needed, but we would have to pay for it. We were old that we have neglected to keep oil in the vehicle.

Between oil change intervals, the check engine light flickered intermittently. I checked the oil level and it was very low. I added 3 quarts of oil and took it to my Hyundai dealership. They performed all the oil consumption tests and told us that the car now burns seven-tenths of a quart every 1000 miles. Hyundai USA claims that this is acceptable oil consumption. I disagree of course. I called my service adviser at the dealership and requested that Hyundai replace the engine because a 2015 Hyundai Sonata with only 70K miles should not be burning that much oil. He agreed and told me to keep monitoring the oil consumption and if it burns 1 quart or more after 1000 miles, to bring it back.

Oil consumption issues. Had a brand new factory motor to replace original motor due to engine failure from oil consumption issues on June 29 2020 at 154,285 miles. The new motor only has 56,665 miles on it and I'm having to add extra oil in between changes because it is bone dry after about 1800 miles from oil change each time.

The vehicle is demonstrating clear signs of engine failure based off the symptoms Hyundai states on its website for the rod knock bearing recall (no power, enters limp mode, white smoke out tailpipes, etc.) Hyundai states vehicle passes testing. Engine also has oil consumption issues, has had its PVC value fail twice in ten months, and burns through 1.5 qts of oil every 496 miles (has failed all 3 consumption tests). The vehicle has stalled out on multiple occasions and risked my/my child's life, has required cylinder cleanings and fuel injection cleanings, and the engine gets extremely hot. This is the second failed engine in the Sonata, and Hyundai has not stated if they will replace it.

After Hyundai Dealership performed RECALL 953, vehicle is having uneven engine idling, especially while stopped at traffic lights/stopsigns and when starting the vehicle. It is noticeable enough that I am concerned the theta ii engine is failing, or about to fail.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving at an undisclosed speed and approaching a stop light, the brake pedal was depressed, and the vehicle stalled. The contact shifted to neutral and pushed the vehicle off the road and parked in a nearby lot. The contact stated that the vehicle was inoperable. The vehicle had not been taken to the dealer to be diagnosed. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 180,000.

My oil is burning with in a weak. And flludding out my spark plugss And then when I push the gas, my car just vibrates everything and it doesn't wanna go..Iknow other models were recalled for this issue . This issue has been fixed twice and it keeps happening.

My son was driving my car home from work and while waiting at a light, he went to go in the car would not move the engine. He just died right there in the middle of the street on him. He was stuck in the middle of the street for quite some time waiting for a tow truck because it was way too dangerous for him to get out of the car. It was during traffic hour. The car only had like 48,000 miles on it. After repaired by the dealer car started having other issues with the engine light coming on with intake manifold but dealer claimed that part is not covered, which that part is part of the engine that they supposedly replaced.

Insurance companies are not proving insurance because of rise in theft of Hyundai vehicle. Now they are asking to install remote start kit for physical engine immobilizer. Cost of this installation is $350 - $500, Hyundai is not entertaining this issue. Hyundai are saying we have done anti theft software update but insurance companies are saying that is not enough.

Hybrid system warning comes up often and everytime I take it to get assessed, something different is getting fixed. These repairs are all expensive out of pocket repairs. The problems continues to happen and I’m constantly repairing something different.

Vehicle displayed hybrid warning while moving through an intersection on a highway. The car's engine turned off along with the power steering and brakes. Had the light not been in my favor, I would have been unable to stop on a high speed highway with oncoming traffic.

I am 86 years old. I bought the car brand new so I am the original owner. I have kept the car perfectly maintained and garaged from the day I bought it. My wife is also 86. She and I are the only ones that drive the car. To date, it has 73,822 miles on it. The main issue I am having is random, unpredictable stalling and hesitation when trying to accelerate. We have also had unintended acceleration. This always happens at the worst times which causes grave concern for our safety. We have taken the care to the dealership here in Cape Girardeau, MO called Chris Auffenberg Hyundai. They've charged me $130 only to tell me nothing is wrong. I have continued to try to work with them and they now have decided a new fuel pump will fix this which is $730. I have noticed there are already...

The driver's seatbelt does not retract. The engine is burning oil.

The contact's friend owned a 2015 Hyundai Sonata. The contact stated that while her friend was driving at 20 MPH, a motorist informed her that there was a fire visible underneath the hood. As her friend opened the driver-side door, the vehicle became engulfed in flames. The contact's friend was taken to the hospital where she sustained severe burns to the left side of her body. The contact's friend had her skin grafted from the right side of her body to repair the severe burns sustained to her left thigh and ankle as well as other parts of her body. A police and fire report was filed. The vehicle was completely incinerated due to the failure. The remains of the vehicle were towed to an independent tow yard where it was deemed a total loss. According to the fire report, the fire was caused by an unknown electrical failure malfunction;...

This is the second engine that has been replaced for the same issue. It had a connecting road bearing failure & went into limp mode.

Car stalls intermittently. When at a stop sign or red light, then when my turn to go I step on gas peddle, car starts to go, then stalls. I have to let off gas pedal and step on it again to get car going. This is dangerous as it leaves me in intersection and vulnerable to oncoming traffic. I had a mechanic check it out and they cleaned Throttle body, but that did not fix problem. No trouble codes showing up apparently.

over the course of this last year I've been in contact with Hyundai motors of America and my local Hyundai dealership after my 2015 Hyundai was showing signs of engine issues i was traveling along i-95 with my child at highway speeds when my car suddenly came to a stop causing panic and what could've been a tragic accident. had I wasn't able to regain control of my car. I was told to schedule an appointment which I did that same day taking my car in for service where I learned about several recalls on my car make and model. I was informed that a update was need along with knock sensor detecting software since that initial contact I've taking my car back to the dealer regarding smell of something burning and excessive oil consumption. my local dealership have since performed Nemours oil consumption test finding issues and picking and...

Consuming 1 quart of oil every 2 weeks, which is about 800 miles of highway driving for me.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 30 MPH, the sunroof detached from the roof of the vehicle. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The vehicle also experienced severe engine knocking and the vehicle was taken to the local dealer who diagnosed that the engine was faulty and needed to be replaced. The engine was replaced, and the vehicle was repaired. In addition, several safety features including the Lane Departure, Cruise Control, and the Forward Collision Avoidance system intermittently malfunctioned. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure. The failure mileage was approximately 92,000.

Engine light came on, checked the oil and there was no oil in the engine.

I purchased a 2015 Hyundai Sonata from Carmax on 12/6/22 in Tinley Park, IL. The motor on the car went out on 8/30/23. I took my car to family mechanic to find out that the motor has a hole in the back of it. I had it towed to Happy Hyundai on 9/1/23 in Oak Lawn. I was by Happy Hyundai that they will not be able to look at my car for for 4-6 weeks. Carmax claimed to have did an all point inspection on the car but yet the motor went out. I’ve only had the car for 8 months. The motor went out while I was driving on the express way going over 50 mph. My safety and others around me was put at risk. Luckily me and no one was hurt. The only time the engine warning lamps came on while I was on the expressway...

What component or system failed or malfunctioned, and is it available for inspection upon request? My engine stopped working while I was driving on the highway from Texas to Norman. This happened when I tried downshifting from 6 to 5. How was your safety or the safety of others put at risk? I had to find a way to maneuver from the fast lane to the side of the road without putting myself or any other road user at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? After several failed diagnoses from different specialists such as auto locksmiths and other mechanics looking at the alternator and starter as possible causes of the problem, I had to have it towed to the Hyundai dealership in Norman to have it diagnosed and I was told that it was very likely to be an engine recall...

I have taken my car to mechanic and they have told me that my car is leaking gasoline. They recommended that I go to the dealer. When I called the dealer they told me that I would have to pay for the diagnosis. This is obviously concerning as gasoline fumes are toxic. There has been no warning lamps turned on this whole time but can definitely smell it when I finish my ride.

Engine just stopped while driving This should be apart of the attached recall but it is not showing when looked up by my vinn. How to update this?

The contact owns a 2015 Hyundai Sonata. The contact stated that two weeks after having the oil changed, the low oil warning light was illuminated on the instrument panel. The vehicle was taken to the dealer and the contact was informed to not add oil but to bring the vehicle back to the dealer at 1,000 miles driven. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.

While turning in an intersection on a highway, car displayed check hybrid system and shut down. power steering could not engage so braking and turning was almost impossible. Car had to be towed, was not able to be restored

Engine failure due to a problem with the type of engine. Hyundai denied warranty and class action settlement claim, due to exceptional neglect. All oil changes etc were accounted for. the car with no warning, had been driving great, lost all power and left me and my two grandchildren on the side of the road. The Hyundai dealership confirmed that the engine was blown. There were no warnings

The engine and yes it is. Because my car turned off in the middle of the loop on the highway when there was a lot of traffic and we could have gotten hit. No it has not been. No it has not been. We were driving on the highway then the engine started sputtering and it wouldn’t go faster then 40 when I tried pulling off to the side that’s when the engine ,battery ,and oil light turned on and after that the car just shut off and wouldn’t want to turn back on.

While driving, received Hybrid system warning that shut the car down . Power steering and braking were non-existent so safely stopping and pulling over was near impossible.

My 2015 Hyundai Sonata has recently been having both electrical and engine problems. Roughly a month ago, I had my vehicle completely stall in the middle of the highway. I lost power and a bunch of lights came on at once. Thankfully, I was in the right lane so I was able to safely get off the road even though I had many other cars speeding around me. I had no acceleration, I was just cruising off the highway at this point. Thankfully, my brakes did still work. Engine light and a bunch of errors turned on but went away once I pulled off and restarted the vehicle. I pulled off the road and once I decided to try and start it and go again, my car felt like it had hardly any power the whole way home. Fast forward to last weekend, I was driving home and my car...

I am unsure what exactly happened but it is giving an error code for the engine sensor. I was driving the expressway (55-65MPH) and my car went directly into safe mode. Which I didn’t kno what it was til later. I went from going expressway speed to almost getting t-boned getting off of the exit ramp as I was unable to accelerate over 2RPMs. So my acceleration would jolt my car when going over 2RPMs. I made it to a gas station where I had my mechanic friend meet me. He said I had no oil. We put 4 quarts in and it barely did the job! I had gotten my car serviced and oil changed not too far from when my car began to “shut down”. So oil is in the compartment, the engine light turns off. Well then I’m driving the expressway AGAIN thinking the problem is solved...
