general problems of the 2017 Hyundai Sonata - part 2

This is the third time after 3 “repairs” that I have had my car at the dealer in less than a year. Car went into “limp” mode while driving down the highway causing car to stall and not go over 20 mph. First time they said it was a technical update needing done. Second time said low battery power causing issue so I purchased $300 battery from dealer and now showing cylinder 4 misfire and recommend replacing spark plugs and oil combustion testing due to having to add 3 quarts of oil every 230 miles due to excessive oil consumption. Dealer said this will not fix the issue however so why would I pay to have it done if it won’t fix the issue. Luckily these three incidents of engine power loss hasn’t caused me to have an accident but what if in 3 months and my engine loses power without warning for the 4th time in a year it dies cause an accident. I have a case open with Hyundai but am getting nowhere. I feel like a measly engine replacement would cost less than it will cost if this causes a major accident soon.

Excessive amount of oil burning. Was told that this vehicle had a engine recall, and I am trying to see what I can do about it before it blows up.

Fail/malfunction 3/18/internal engine failure diagnosed by local avondale, az Hyundai dealership service - rod bearing failure suspected. Vehicle currently undergoing bearing clearance test to affirm this or any connecting rod issues, with possible need for total engine replacement. When googling "Hyundai Sonata hybrid 2017 internal engine failure," masses of reports generate from consumers with this model, complaining of same defect, as do numerous recalls for such defects that have been mandated for the model with range of years including 2017. Yet when searching with my VIN, it says no recalls have been mandated, in spite of the undeniable, widespread identical defect. Available for inspection. Safety risk: driving on the freeway in city traffic at 70-75mph, the engine completely stopped and all dash lights lit up at once. Vehicle had to be coasted to shoulder to wait for roadside assistance. Extremely hazardous to us in vehicle and to all around us with sudden, dramatic speed change in moving, constant freeway traffic. First time: our usual mechanics at pep boys did diagnostic but found nothing, the vehicle drove normally for them, yet they did our regular tune-up, oil change, etc. Two weeks later, the same event happened on freeway, identical to first time. We were very lucky that no crashes happened either time. Pep boys advised that Hyundai investigate the issue. Prior symptoms: no warning lights or sounds presented until the events themselves, when the entire dash lit up. However, in the couple of months before, there were occasional, slight hesitation moments in the motion while driving at any speed. Concerns: 1) it seems Hyundai is on track to want to charge me for an entire engine replacement, or for whatever engine repairs they deem, e. G. Connecting rods, for manufacturing defects that they are entirely responsible for, 2) no recall seems to be mandated yet for this VIN batch, and 3) too many consumers are in danger - physically and financially.

My Hyundai Sonata sport had a manufacturer defect causing oil consumption. When my engine starting having issues they replaced it for free. I got it back and the engine light came on so I called they ask me to bring it back and I did. They told me the code was a po326 powertrain control module or faulty knock sensor. They said the code was a history code and they cleared it out drove it and the light did not come back on. I picked it up drove it and the light came back on. I called they said bring back again and before it could get it back over there the transmission went into limp mode or safety mode. They said my transmission was gone and needed a a new one. $4385. 44. I wasn't having any issues before the engine replacement. All other mechanics think something happened when the replaced the engine. I just dont want to be taken advantage of. Long Hyundai chattanooga tennessee.

Car has been burning oil since September of 2024. It’s burning 2 quarts of oil every 500 miles. The oil is burning out spark plugs and coils every 3 months. These engines need to be recall and Hyundai needs to be held accountable.

I was driving on highway when all of sudden my vehicle began to shake hard and lose power, every time I stepped on the accelerator the check engine light came on, this happened on February 22,2025 in los baños, CA. My safety was at risk as all other traffic was going past me including semi trucks as I was trying to find a safe place to pull over out of harms way, as I was doing this the car shut off completely before I could even pull over. I had to get the vehicle towed to my local dealership where they had it for almost 3 weeks now, only diagnostic I’ve had back was that it has 2 misfires, one in cylinder 2 and the other in cylinder 4, and that it has no compression in cylinder 2. They said it isn’t covered under warranty which I believe should be looked into as I could of been serious hurt or lost my life due to this issues. I’ve had the vehicle serviced up to date since I’ve owed it and also noticed high oil consumption, not sure if this led to engine failure? the final diagnosis from hyandai dealer is that engine is no good anymore and need replacement but it’s not covered under warranty.

Every few months my car’s engine struggles. It doesn’t start, or I have to try a few times. For whatever reason I need to get an oil change a lot more frequently than normal and I’ve been to the shop before and the shop tells me that my engine is recalled but it doesn’t say that on the website when I put my VIN number in. Whenever the engine stops working again sometimes the ac doesn’t work and it almost put my dog’s life at risk once.

E vehicle is burning approximately 2 quarts of oil every month with no external leaks. This indicates severe internal oil consumption, which is a known defect in Hyundai’s theta ii 2. 4 gdi engines. I discovered oil inside the vvt solenoid electrical connector and on other wiring, which shows oil is traveling through the engine harness. This causes hesitation, rough running, and the risk of sudden engine power loss. The vehicle feels unsafe to drive because the oil level drops quickly, and the engine could seize or stall while driving. Hyundai vehicles of this generation have a history of excessive oil consumption, piston ring failures, and engine fires, and I believe my vehicle is experiencing the same defect. This is a serious safety concern.

I am writing to file a formal safety complaint regarding my 2017 Hyundai Sonata which suffered an unexpected engine seizure on January 22, 2025, while my daughter was driving. The incident occurred without warning and left her stranded in a hazardous location, putting her in immediate danger. This appears to be part of a wider, documented issue affecting Hyundai vehicles. My understanding is that engine failures—particularly in Sonata models—have been the subject of recalls and class action lawsuits. However, Hyundai motor America has refused to replace or repurchase the vehicle. Instead, they replaced the engine with one that now carries less warranty coverage than the original (12,000 miles vs. 26,000 miles remaining). Since the engine replacement, the vehicle has presented new problems, and now needs a new battery after sitting on the lot for so long. Hyundai has failed to offer meaningful support, leaving my family without a reliable vehicle for over two months. Hyundai has refused to replace or repurchase the vehicle, and I am now stuck with a car I cannot drive, cannot sell (due to the engine failure now reported on carfax), and cannot rely on to safely transport my daughter. I believe this represents not only a serious safety risk, but also a pattern of negligence that could affect other drivers unaware of the risks. I respectfully request that NHTSA investigate this issue further and consider expanding oversight into Hyundai’s handling of these engine failures. I am available to provide full documentation, service records, and communication history.

The vehicle had a recall to replace the motor for bearing failure. They replaced my motor at 101,000 miles. The second motor than failed for the exact recall of bearing failure at 65,000 miles on the new motor. They told me that since I had already have done the recall and my car was now out of warranty that I would have to pay 10% of the repair bill for another motor. This second motor should have been included in that recall.

Upon inspection, the contact noticed that the engine oil level was low after an oil change. The contact stated that three quarts of engine oil were added every two to three weeks. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 114,606.

Unknown. . . I recently got an oil change and not even a week later my oil light came on. There's no leaks, I've been to midas several times and no leak was found. Was told to check to see if it had any recalls, my VIN doesn't produce a recall but I know there's something wrong with my car.

Driving home car just shut off still had power to steer and brake but no engine. Pulled it off the main road and it leaked oil but still no engine. Already had the dealer replace the intake manifold at my expense despite Hyundai knowing the plastic lever inside fails. We were lucky the snowplow was going the opposite direction as the weather was horrible as we got closer to home. I have a dead car in my yard waiting to have a dealer look at it. We could have been killed due to fault of engine.

The engine started knocking while I was driving around a lot of cars and while I was going to autozone to see why the check engine light was flashing on my car wouldn't accelerate and randomly started stopping and I was fearing for my life when I was going on the highway to go back home. For almost a year now I noticed the oil in my car started burning more and more like I would only drive 1k miles and it would already be done with, so I had to replace it. Hyundai knows this is a problem with this car because I called and asked them about the oil and told me specifically it's an engine problem once it starts knocking then you can come fix your car but want me to pay and fix the whole engine and work process.

The makes a weird shutter noise when accelerating and won't crank over 60. Loses power when turning or when going uphill. Sometimes has problem starting. Enging light came on twice blinking, once I changed the battery it went off and was working fine. Now it's back on again after a few weeks. Plus my oil tank still comes on and I've just received and oil change. I just bought the car in August of this year, dealership sold to me with a faulty battery.

I am writing to request a goodwill replacement. My car is burning oil faster than I can put it in. The engine heats up so bad that I feel it could catch fire at any time. I loose acceleration because of this, its an extreme safety hazard for myself and other motorists on the road. I am just now finding out about the issues Hyundai Sonatas are having with this said problem. I would like it fixed ASAP.

The engine is losing oil at a much higher rate, causing a knocking sound. Not accelerating at it should without the sound getting louder and hesitating. This vehicle has been inspected by a licensing mechanic ( goodyear). The check engine lights and multiple codes have appeared while driving for about the last 4-5 months.

Motor burning oil with no leaks causing it to need replaced, with out any reasoning.

Engine is burning oil. Ticking sound when engine is idling.

I am seeking a resolution to the concerning and potentially dangerous issues that I have experienced with my vehicle. I got it from carvana Dec 2023 and only had it for a year, and I’ve only drove 19,000 miles on it before my engine cut off on me while on the highway. I was going 70 mph when the safety of my life was at risk. After, I tried to send it to the dealership, they let my car sit for a month before even looking at it, they couldn’t tell me because they let it die. My car was completely off. So I got no full diagnostic. I have personally endured the traumatic experience of my engine suffering catastrophic failure. Also, my vehicle was consuming oil at an alarming rate, necessitating frequent and costly refills. I would sometimes even go 500 miles before the due of an oil change and would be told that my oil is very low. I believe that these problems should not be considered normal wear and tear. The hybrid Sonata 2017 had a engine recall and so should the Sonata 2017 limited 2. 4l.

Vehicle is burning oil. Have been using fully synthetic oil at regular 3000 miles. And have been increasing “burned” more oil before each oil change. Valvoline instant oil change is the shop I’ve been going to for my oil serviced maintenance. My last visit I had 1 quart of oil left in my engine.

While driving at a high rate of speed propulsion to the vehicle suddenly and without warning ceased, the electric and internal combustion engine were non-responsive (ice stopped; hybrid motor didn't provide propulsion), the warning light said "check hybrid system. Turn off engine" I was put at risk because I was traveling at highway speed and was given no warning before the vehicle shut down. This has occurred nine times, I've reported all to Hyundai, they have had the car in the shop three times, the issue is not fixed. No, despite odb2 error codes, the car has not shut down while a dealership is driving it. Yes, the vehicle has been inspected multiple times by Hyundai. Yes, always "check hybrid system. Turn off engine", in almost all cases the check engine light comes on after that, and in some cases additional lights such as "auto hold". This first occurred in Dec 2023, I was told the car was fixed (it wasn't) and happened again in October 2024. I haven't been able to drive my car since then.

I have to add a quart of oil to car a day tul the motor blew.

The drivers seat belt does not engage. The engine has been burning oil, misfiring, and even after thousands in repairs was returned to me by the dealership with continued misfiring. When returning the car back to the dealer service center days later after hurricane helene, the car continued to misfire and became so overheated the engine light was flashing. Upon calling for a tow, I attempted to raise the hood for the driver to locate the car, but the hood was so hot it burned my hand. The engine was so hot, I believe it was about to catch fire and would have had I not been able to pull over so quickly. Had I been driving on the interstate, I have no doubt this car would have been on fire within minutes.

2017 Hyundai Sonata having severe oil consumption issue. Having to top off with a quart of oil every 500 miles. Was purchased last June and has been a nightmare since. We contacted Hyundai consumer affairs and they opened a case and made an appointment for us to go to a local Hyundai dealer. The dealership told us we didn’t qualify for oil consumption test be cause we are second owners and the vehicle had 62,000 miles on it. We did purchase an extended warranty when we bought the car but they won’t cover oil issue. Local mechanic won’t touch it and refers us to Hyundai dealer. Just getting so frustrated and worried about car safety and engine damage. I read on another sit that Hyundai issued an oil consumption recall in 2025 but our vehicle is not listed. Please help us.

My engine burns oil like crazy. At least 1 qt every 1,000 miles or less. Took to dealership and was given a hard time about it having an issue. Now my power steering light keeps randomly coming on. I'll feel the steering start to get hard to steer. Thought I needed belts so I replaced both serpentine & water pump belt but it still happens. When my power steering light comes on and steering wheel locks up, I have to put the car in park & rev the engine to get the light to turn off. Mechanics said all pulleys are in good shape so not sure what's doing it. My lights also start to flicker when power steering light comes on. I have a new altenator and battery so it's not caused from that. I have no idea what's causing it but it's extremely dangerous!!.

Excessive or consumption. Purchase a car three weeks later car started misfiring I was able to get the car to a mechanic shop. I was told that the car needed a tuneup, spark plugs and ignition call was changed mechanic noticed oil on top of the engine and advise me to get an engine gasket. Gasket was replaced 2 weeks later oil light comes on I added 5 quart of oil the light goes off I notified the mechanic again was able to get the car in the shop took mechanic replaced the gasket week later oil light was flickering took the car to have oil change. There was no oil in the car, three weeks later oil light flickering again checked oil it was empty I added five more quarts to the car and took the car back to the back the mechanic one he inspected it he informed me that the engine in the car for some reason consume a lot oil and that I should take the car to Hyundai dealership. I checked Hyundai recall for the oil consumption issue the car model I have is not apart of the recall. I could have lost my life when the car stalled due to oil is leaking where the spark plugs are located. Hyundai need to recall all 2013-2017 Hyundai Sonata and elentra.

Bought a car. In couple days check engine light came on, it was blinking and car was put on limp mode, rpm between 1800-2000, speed 60-62 mph. Went to dealership they did full diagnostics, told that they are going to submit to Hyundai to replace engine at their cost. Hyundai came back that they want to replace knock sensor and then see what’s gonna happen. I replaced and was told that I have to pay even though there is a recall on knock sensors. They replaced the sensor which was over 600$. And the problem came back in less than 36 hours. Now the vehichle is back again at the dealership and they gonna do diagnostics again. Which is ~200$. I need to help this resolved as I’m only being ripped off with no solution. The VIN says it doesn’t have any recalls, but vehichle is experiencing exactly what’s on recall. The vehicle has been in the shops for a month now. Thank you.

The vehicle itself shakes when accelerating and will start to fail once 60mph is hit. It will also cut out when left turns are made. . . I have met 4 people with the exact same issues who received recalls but I am not sure why my car is not included. I was almost rear ended on the highway by a semi with my pregnant wife and 4 year old son in the car because of the engine failure.

The contact's daughter owns a 2017 Hyundai Sonata. The contact stated that while driving at approximately 55 mph, the vehicle lost motive power, failed to accelerate, and went into limp mode. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, who informed her the failure was due to code p1236. The vehicle was taken to another  independent mechanic, who determined there was metal in the oil and an engine replacement was needed. The vehicle was towed to the local dealer, who diagnosed the vehicle and determined the computer needed to be reset. The vehicle was repaired, but the failure recurred. The vehicle was taken to another independent mechanic, who confirmed there was metal in the engine and the engine needed to be replaced. While the owner was driving, at an unknown speed, the engine seized. The manufacturer was not contacted. The approximate failure was 150,000.

While driving, car started to lose power. Warning lights started flashing to turn off vehicle to recharge battery. Car lost all power. Car was towed to dealership. Dealer started diagnostic testing, and first thing that was noted is that all oil had drained from car and that crank shaft may now be damaged. Prior to incident, no warning lights came on for service, engine or oil lamp. Dealer and internet searched confirm this has been happening to this model recently.
