general problems of the 2017 Hyundai Sonata - part 2

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.

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.

The car is burning through oil at an excecated rate. This is a well-known issue with this make and model. The dealer said they fixed the problem, and they did not. This engine needs to be replaced. It was inspected by a mechanic not affiliated with Hyundai. Hyundai has refused to replace the engine. This should be covered by the 15 year/ 150,00 engine warranty. This engine could seize up at any time. It is a hazard to be driving. The driver is an 80-year woman. She needs help.

Apparently there has been a leak in the engine and was not retaining any oil. We’ve tried to fixed it but it wasn’t fixed properly. My safety and others were at risk by the car shutting down at any moment. I have not taken it to the dealer yet. I am willing to do an inspection at a dealership for a better understanding on the issue. Check engine light came on about a month ago and I kept trying to fix it but check engine light is still there.

Me along with thousands of others are experiencing the “excessive oil consumption” issue. Hyundai is doing nothing except making us pay tons of money for testing when they already know what the issue is and is refusing to do anything. Enough is enough. I can’t afford a new car nor should I be forced into buying one. The dealerships have been instructed by Hyundai USA not to admit negligence or helping g the car owners.

The contact owns a 2017 Hyundai Sonata. The contact stated while driving 65 mph, the vehicle stalled without warning. The vehicle was towed to an independent mechanic and the dealer; however, the cause of the failure was not determined.

The vehicle remained in the possession of the dealer and was not yet repaired. The failure mileage was 107,084.

To whom it may concern, I would like to inform you that I have been experiencing engine power loss and oil evaporation from my Sonata. In fact, I took the vehicle for an oil change in April 26, 2024 and by August 1, 2024, my car was not accelarating and the dashboard was completely illuminated with the engine, air bags and suspension lights. Upon inspection of engine oil dipstick, I was made aware that my oil was missing (evaporated) without any visual undercarriage drips. Therefore, I added 4 qts of synthetic oil to my car recently replaced oil and the car continued without power. Upon connecting a vehicle code reader, it was reported that a spark plug was malfunctioning and I continue with its replacement. To date the vehicle continues to have engine loss of power episodes. Can someone please help as I do not want to die in this vehicle due to a manufacturer's unannounced/undisclosed engine issue. Thank you for your time and consideration.

My vehicle was purchased in 2018 and currently has 128,000 miles. I took it to the dealership because it was puttering and not holding pil. The dealership did some work on the vehicle. Furthermore, after that trip to the dealership, my car kept burning oil even after recent oil changes that I found myself constantly adding oil. I took it to another licensed mechanic who informed me after a tune up that my car is consistently burning oil. This was after I had a recent oil change. The engine is defective, Hyundai knows they are defective and refuse to do anything about it.

My 2017 Hyundai Sonata has a major oil consumption problem. The car does not leak oil. It burns oil average 3000 miles. I have to add 5 to 6 quarts of oil every time I bring it to the shop and ask about it they tell me Hyundai has a problem with one of their engines, I see the recall on other models, but not my model. It’s been ongoing for about a year.

Engine burning oil like crazy never had to put so much in for any other car. Risk of engine lock without enough oil also sets of the knock sensor. Every time I get an oil change they let me know that I’ve burned most of my oil and that it’s low so I just started doing my own oil topping it off. Problem has been ongoing since I got the car.

I am writing to request your assistance in enforcing the terms of the class action settlement and extended warranty coverage for my 2017 Hyundai Sonata (VIN: [xxx] ). Despite clear evidence of a defective theta ii engine, Hyundai corporate has refused to authorize a full engine replacement unless the engine “blows” completely. This directly conflicts with the express terms of the “in Hyundai and kia engine litigation” settlement, which requires Hyundai to cover any engine exhibiting failure?mode symptoms. Below, I have summarized all relevant facts, diagnoses, and correspondence. I purchased this Sonata used from oakes kia (kansas city, mo) in may 2023. At the time of purchase, the vehicle had 77,000 miles. To my knowledge, I am the third owner of this vehicle. Since I bought this car, I have followed the manufacturer’s recommended maintenance schedule: all routine oil changes (every 5,000 miles, or sooner) at oakes kia, plus one oil change at northtowne Hyundai in April 2025. The engine currently has approximately 98,650 miles. I have driven it about 1,000 miles since December 2024 to avoid further damage and due to the danger, it puts me and others in on the road. Since December the vehicle has had persistent shaking, hesitation on acceleration, strong odor, and illuminated check engine light. Car condition has worsened since last oil change and even after coil packs and spark plugs were replaced, there was no improvement. The last oil change was done at oakes kia along with a tire rotation and multi-point inspection. They installed um018 ch074: mobil sp 5w30 sn, 21513 23001: gasket-oil plug and 26300 35505: filter assy-engine o service advisor, fernando perez said they did not identify root cause of the shaking, hesitation and strong odor; they instructed me to return to the mechanic who had replaced spark plugs/coil packs, possibly I got a bad spark plug or coil pack. I did this, it was not the problem. I have files to share but they are too big! information redacted pursuant to the freedom of informatio.

The engine light keeps going on and off and I reported to their dealer a couple times during the warranty but when they checked the car the light got off and they asked me to keep driving it until out of warranty and they ask me to pay for fix the same problem.

In early June 2024 while driving 65 mph vehicle started shaking, engine and oil light came on, losing power, noisy and only would go 50 mph max. When destination reached, checked oil level (was low) added oil. Took the vehicle to auto repair shop. Review showed a misfire in cylinder #2 with plug oil fouled and recommended new engine. The car was taken to the Hyundai dealer who performed various diag. Procedures via communicating with their techline who ended up rejecting the request to replace the engine due to the milage (136k) being out of warranty. They would replace engine if the connecting rod bearings had wear or damage. Hyundai national consumer affairs contact given for the case refuses to listen to any information given and only states vehicle is out of warranty. Hyundai knows this engine has manufacturing issues causing them to wear out prematurely including excessive oil consumption. They should extend the warranty to at least 150k. Afraid to drive car as engine may suddenly stop or catch fire causing accident/injury to occupants. Please help!.
