2015 HYUNDAI SONATA Engine Problems

While I was driving, my check engine light came on. It wasn’t flashing so I was going to continue driving to a parts house (because the dealerships around me were closed) and have them check the codes that were present. Immediately after I had that thought, I noticed the car was smoking and the battery light and the traction control light had come on, so I proceeded to pull over and shut the vehicle off. I got out and noticed the hood had soot on the edges. I called 911 and watched the car go up I’m flames. This all happened in less than a mile. I noticed a fluid of some sort had sprayed out of my vehicle onto the road and the underneath the vehicle was coated in the fluid. This is still being investigated but I know of a lot of Hyundai/Kia vehicles have caught on fire...

on aug 18 i was driving on the interstate at 80 mph , suddenly i could no use my gas pedal it lost power , the engine and oil flashed lucky i was able to get my car pulled over out of harms way and called a tow truck , i had it towed to my nearest Hyundai dealership ,on september 22 my car was denied for engine replacement due to me being the second owner , i've only had this car a year , i would like to warn any one with a Hyundai to take caution because their is no warning signs until it happening .

My power steering light came on last night when I arrived from work on Saturday night. Was hoping to take it in to be looked at but the dealership I bought it from is closed till Monday at 10. Woke up Sunday for work decided to see if the light was still on but it was off but about 7 minutes into the the light came back on along with the abs light, engine light, and oil light. I believe a couple more lights came on but not sure which ones but the car stopped working and starting completely

The issue is with the hybrid system, which malfunctioned and apparently ruined the rest of the car. The damaged components are adding up to over 75% of the car's value. The vehicle slowed and stopped suddenly on a busy road when the issue started. Currently, it has been inspected by two different shops and they have both given me the same diagnosis.

My daughter was driving on the interstate when the car went into limp mode and the engine light was flashing. We had it towed to hyundia dealership where they did an engine update. Had it for 3 months when it did the same thing to her again. Had it towed again to same dealership where they are telling me it needs a new engine.

We had taken out 2015 Hyundai Sonata to the repair shop because the check engine light came on. The repair shop said it gave the error for low oil, but the oil in the system was not low and we were barely past the oil change mileage. We had the oil changed and picked the car up. The next day, the car lost all power and locked up completely while going about 45 mph down the highway. We had to push the car off the highway. Car was towed to same repair shop and we were informed the motor was blown. We called Hyundai but they offered no assistance since we were past 100,000 miles. The engine blew at 114,000 miles.

The contact owns a 2015 Hyundai Sonata. The contact stated that after having her vehicle serviced under NHTSA Campaign Number: 21V749000 (Exterior Lighting, Electrical System) the exterior and interior lights would turn off while driving at various speeds, with the check engine and oil warning lights illuminated. The contact also stated that upon using the turn signals, the headlights would intermittently turn off; however, the headlights would turn on upon toggling the light switch. The contact had initially taken the vehicle back to the dealer where she was given a diagnostic fee to determine the cause of the failure. The vehicle was then taken to an independent mechanic where she was informed that the E-CVVT actuator was defective. In addition, the contact also stated that the vehicle would hesitate upon depression of the accelerator pedal or lunge forward upon depression of the brake pedal. The independent mechanic linked the failure...

My wife is concerned for her safety and our three children. On start up and driving engine feels like it's shutting off and turning back on. I was told by a local mechanic that there are several issues that Hyundai knows about and basically aren't fixing. Engine light keeps coming on and off with a different code everytime. Issue has been going on for about a year replaced spark plugs and had decarbonization process done to no avail.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 45 MPH, there was a cranking noise coming from the engine. There was an engine overheated message displayed. The vehicle was towed to the local dealer. The dealer diagnosed the vehicle with engine failure. The vehicle was then towed to another dealer who diagnosed the vehicle with engine failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 127,785.

Engine failure while driving on freeway. Lost control unable to accelerate, almost got hit by semi due to inability to move out of way swiftly. All engine oil came out due to rod bearing punching hole in engine block and car started smoking, fire department said I had maybe 2 minutes before my car would’ve been engulfed in flames.

The engine constantly needs oil added. There is no oil leakage showing on the ground. I have to add oil ever week. The engine also knocks going at slow speeds up hill and has started knocking when started if you turn it off and restart it it will run ok. The dealer says the engine has to fail completely before the recall will be completed. So I have to drive it until it fails somewhere on the highway and could easily cause a serious accident.

2 recalls were found on my car and a service campaign. After taking my car to a couple auto shops, within 2 years my car has had the same repair issue involving P010 & P011 codes. After researching and finding there was a service campaign and 2 recalls, I decided to take my car to the dealership due to address the recalls. I took my car in on 8/1 and had a full inspection done on my car. Outside of the normal wear & tear, I was advised that the ECVVT cap was installed incorrectly, that it was leaking oil. I was told that cleaning the oil & reinstalling the cap would correct the problem, it didn’t and I’m out of additional money ($562) and the problem is reoccurring. I’ve called several times recently, as well as one of my mechanics, hadn’t received a return call not until I filed...

Engine problem. Massive oil consumption. We bought our 2015 Sonata new and have taken it for service and maintenance at the dealership. I have all records from dealership maintenance. Have been told that its just normal for that engine and to keep adding oil. Now I have to check and add oil weekly or it will be empty. Started having issues in 2017. Hyundai knows there is a problem with the engine. I dont know who to talk to or what I can do.

It happened with me twice when I noticed that after about 1800 miles after my car’s oil change, the oil light comes up when there’s a turn or a speed bump. After checking the dipstick, I noticed that there was no oil in the engine. I got it checked for some possible leaks in the car but there were none. This narrowed it down to the cause that the car is burning oil too quickly and that it could also lead to to engine seizure if on a long drive. I also did some research on the same and found that I wasn’t the only one and that there still hasn’t been a recall on the same. I believe it is a safety issue if the engine malfunctions while driving, be it long range or a short one.

The contact owns a 2015 Hyundai Sonata. The contact stated that when the vehicle was started, the check engine warning light illuminated. The vehicle was taken to an independent mechanic who stated that the spark plugs needed to be replaced. The vehicle was towed to the dealer where the vehicle was repaired. The manufacturer was contacted and stated that the vehicle was not under warranty and there was no recall on the vehicle. The failure mileage was 27,055.

The engine stalls out randomly. This is the third time it's done it. The first time was while I was exiting the freeway on March of 2021, which I thought was a fluke. The second time was July 19th and the third time was July 30th. There were NO warning lights or messages. Took it to the dealer and they said that everything came back fine with the engine. They confirmed that the RPMs were too high when it was in a parked position and the engine was on when they first took it in. They suggested I replace the starter. I'm going to a different mechanic for a second opinion. The car was in motion with my foot on the gas pedal when it started to stall. There is no way that it is from a starter.

Engine had a leak and shaves of the engine were inside the oil line. Had to get engine replaced.

Engine burns 2 quarts of oil a week. Took it in for oil consumption tests and Hyundai figures out ways to not replace these faulty GDI Engines. Also car has a strong gas smell inside car. Maybe gas leaking. Airbag warning light has been on for years. Took it to the dealer in the past they said it's ok(Hub Hyundai Katy TX) but I don't feel confident.

The contact's husband owns a 2015 Hyundai Sonata. The contact stated that while her husband was driving at an undisclosed speed, the vehicle lost motive power. The vehicle was towed to the residence, where it was diagnosed by an independent mechanic with engine failure. The mechanic informed the contact that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

Multiple times, when the car start up and is put in to reverse, there is no throttle response. Simultaneously, it can not be put into the manual gear select mode and the car lurches into second gear.

Driving at 55 and the engine blew. No warning, no check engine light, no sign of anything wrong. Power steering loss, limo mode activation. Almost rear ended during catastrophic failure. 111,000 miles

The vehicle is slow to accelerate and as its accelerating it often will jerk or hesitate roughly. There have also been times when accelerating, such as getting on a highway, that the whole (what I assume to be) throttle system will almost stop and it feels like the car is just going to stop right there on the highway. It's very dangerous as cars behind me are also accelerating and not expecting my vehicle to just stop. The vehicle is available for inspection. There are no warning lights, messages, or symptoms prior to the issue. It has not been inspected by anyone yet.

Vehicle suddenly lost power while in operation. Vehicle was in motion approaching an intersection. When left turn indicator was activated, all lights on the instrument panel illuminated, the engine shut off, and power steering was lost all while the Vehicle was in motion approaching a intersection with stop sign. Vehicle was able to stop before entering the intersection, but would not start again and we were stranded in the middle of the road. Electrical systems appeared to be working. Battery and alternator are functioning normally. After Vehicle sat for 20min, it then was able to start and moved out of the road to a safe location. Vehicle was towed to mechanic that confirmed Battery health and alternator functioning. Vehicle was then taken to dealership for recall 210 safety repair. Dealership service unable to determine cause for loss of power while Vehicle in operation. No explanation, offer of additional service, or...

The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 75,600.

My ABS lights came on and then minutes later my check engine light kept blinking while my car kept stalling or not let me accelerate in the middle of traffic. It’s like the engine dies but the car is on. It only stalls for a second then accelerates then stalls again and accelerates. Almost caused an accident. Seems that this is a problem for a lot of these models. It’s just crazy how it all happened back to back. My car has been running fine otherwise till that happened.

My Car is burning engine oil at in alarming rate. I put 5 quarts of oil in and my check engine light began to blink and my car would accelerate more pass 50 mph. So in 6 days and 578 miles; my car had less than a half of a quart of oil in it. My car is having engine trouble.

While driving on the freeway the engine began loosing power and there is a knocking sound. My daughter was almost rear ended trying to get off the freeway. The vehicle was inspected by an independent mechanic and i was told the rod bearings are bad and the engine needs to be replaced. The vehicle has regular oil changes and does not consume a lot of oil. No warning lights came on. The dealership refuses to inspect the vehicle because it has a salvaged title. The failure happened at 108k miles.

Engine had knocking then completely froze while driving due to low oil pressure. Car has been well maintained, regular oil changes and just had axle repaired. Hyundai has extended warranty to cover this issue that is common on these vehicles and should cover the cost of the new motor. Consumer spoke with Hyundai corporate and the case number is [XXX].

1/2022. My vehicle start leaking oil. Vehicle was under warranty. Had multiple things replaced. I thought oil leak was fixed. Not even a month later in 2/2022, the vehicle was leaking oil again. Brought it back to dealer & they redid gaskets, seals, etc. Now on 4/22/22, I have not even put 3000 miles on the vehicle since it was at the dealership & there was a knocking noise coming from under my hood. Called the dealership and they said I needed to get it back to them. Oil consumption test was never done because it was assumed that my oil was low because it was leaking. Both times oil was put in my vehicle. On 4/28/22, I was at work and went outside to check my oil and there was little to no oil on the stick. I immediately added 5 quarts of oil which is required for my...

I had closed from work one morning and was headed home. Just a few seconds after taking off, my engine completely shut down. Thank goodness I wasn't in on a highway or at a heavy traffic area. I managed to park my car by the road side & tried to restart my engine, but the car wouldn't start. I towed the car to the nearest mechanic, only to hear that my engine is done & needs replacement. I've constantly kept up with frequent oil changes & always used synthetic oil. Current odometer reading is 153k & I believe the car still has the potential to stay on the road a longer time if the engine is taken care of. I've reported the issue to my nearest Hyundai dealership & they've asked me to tow it to them, but they can't promise that they'll take care of the problem. Worst of...

Was driving with cruise control on and driving close to 70mph and the RPMs shot up passed 5 then the car jerked and my speed had went from 70 down to 50 and 40 the cruise controle turned off on its own and the car lost power but was still on but it just wouldn't drive passed 2 rpms and the check engine light was flashing so I turned around and headed the opposite direction so I could get the car off the road then it made this loud noise sounded like throwing metal inside a metal bladed fan and then the car shut off and hasn't started since. The car did not over heat or have any smoke coming from it.

Was diving the car and experienced system failure, no prior warnings or issues. Had regular oil changes throughout, however, a few days ago in normal driving conditions, the check engine light began flashing and car felt like it was losing power. Had to pull over to the side of the road and shut the car down. Vehicle would not restart and had to have the vehicle towed to the nearest dealer. Dealer informed us that the "engine was locked" and had to be replaced, car only has 62K miles on it. Research online has uncovered others that have had the same experience and issue with the 2015 sonata that has resulted in replacement of the entire engine. Dealer has not confirmed if repairs will be covered, but if we had been in a high traffic area the car losing power suddenly without warning could have resulted in serious injury getting...

I was driving on the expressway. After about 18 miles the vehicle slowly decelerated to a stop. I was able to safely exit the expressway to the side street. I turned the car off for a few minutes. It started back up but has not accelerated pass 20/25 miles. There’s also major oil consumption. Camshaft position & ccv issues yearly requiring sensors to be replaced. Increased gas consumption. There’s also been a humming sound coming from the car that’s not been able to be diagnosed by any mechanics.

The contact called on-behalf of her daughter who owns a 2015 Hyundai Sonata. The contact stated that while her daughter was driving approximately 70 MPH, the vehicle started vibrating abnormally. Additionally, the vehicle inadvertently decelerated to 35 MPH. There were no warning lights illuminated. The driver was able to safely drive the vehicle to the residence.

The approximate failure mileage was 42,000.

I have to continue to put oil in my car and get my oil change every 30 days due to oil leak. I have been to the mechanic and had my oil gasket changed, engine clean etc… and I’m still buying if oil and getting oil changes. I would get oil change and as soon as it gets close to 30 days my oil light comes on.

Major oil consumption going on for years. Took in to dealer two years ago, they know there is a problem. They told me I could spend thousands of dollars to tear it apart to find out what is going on, and also told me to call corporate. I got no where with either, even though they recalled the engine in other Sonata cars, just not our ECO model. Slowly started having throttle issues at 4 to 5 year mark. Informed dealer service center that it wasn't moving like it should when gas was pressed. Now, the car is having major problems with acceleration. Barely would go in reverse, drove 1.5 blocks, speed not matching to throttle, press on gas, barely moving from a stop, going really slow, had to turn around and take back home. Our problem with the car is the same that others are complaining about. The car...

My Sonata is burning excessive oil since January 2022 have to add a quart a week but there is no oil leak.

1/2022. My vehicle start leaking oil. Vehicle was under warranty. Had multiple things replaced. Thought oil leak was fixed. Not even a month later in 2/2022, vehicle was leaking oil again. Brought it back to dealer & they redid gaskets, seals, etc. 4/22/22, have no even put 3000 miles on vehicle since it was at the dealership & there was a knocking noise coming from under my hood. Called the dealership and they said I needed to get it back to them. Oil consumption test was never done because it was assumed that my oil was low because it was leaking. Both times oil was put in my vehicle. On 4/28/22, I was at work and went outside to check my oil and there was little to no oil on the stick. I immediately added 5 quarts of oil which is required for my vehicle. The knocking did not stop....

My 2015 Sonata has been going through at least a quart to a quart and a half of oil every thousand miles. I researched this and found out that the 2015 sonatas have a very common problem where the engine needs to be replaced. There was huge class action suit against Hyundai and I'm worried that this is going to lead to bigger problems for me. I have gone to the dealer for 5 times and they keep telling me I'm not burning enough oil to justify the engine replacement but I'm not comfortable with their report.

There's an oil line to the turbocharger; my guess is to cool the turbo and it came off spraying oil all over the engine compartment and when it hits the turbo the heat from the turbo would create smoke that would get into the passenger compartment and billowing out from under the hood. Hyundai had a recall campaign to fix this issue for the same 2.0T engine but only for Sonata models from 2011-2014 and they deny that this recall applies to my car because it's MY2015. Same car, same engine, same turbo oil feed line and they refuse to honor repair costs for recall campaign 16-01-071. I had to go through this risky incident and then have to pay $720 in repairs that was caused by a design flaw.

Was pulling out of a parking lot and the engine stalled. Would not crank over again. Mechanic took the timing cover off to inspect and found timing chains are all in working order. Will all engine belt driven accessories disconnect and timing cover off. Engine cannot be rotated with a breaker bar. Technician says the bearings are seized.

While driving in city traffic, 45 mph zone, my car suddenly lost power, engine RPMs dropped, engine off, power steering impaired, I had to drift into turnout and assess. Car restarted, and I could drive, but RPMs would not exceed 1700, car wouldn't shift gears, speed would not exceed about 15 mph. No engine warning lights, no oil pressure indicator, no excess heat. I found I could drive at low rpms and manually shift gears to increase speed. I got the car to the local Hyundai dealer (Taylor hyundai, Augusta GA) and it has been there 8 weeks. They are telling me the engine has failed because I failed to change the oil for 14 months. They said my oil pan was empty. They asked me for maintenance records and said they were inadequate, and the engine needs to be replaced, may cost $6000 or more, warranty invalid. The car...
