general problems of the 2017 Hyundai Sonata - part 1

My car is blowing a large amount of white smoke due to the head gasket being cracked, I was quoted 2 grand to fix it. The car is not old enough to need a new head gasket, this is completely due to how the car manufactured and I have seen many other reports of this, there should be a recall and this should be fixed free of charge.

I am filing a complaint regarding Hyundai motor America’s handling of my engine-related safety issue, buyback process, and rental reimbursement. My vehicle was towed to elder Hyundai for a suspected engine failure. Elder Hyundai informed me that my car was covered under an engine recall campaign and that they would submit a request for free repair. Shortly afterward, Hyundai motor America notified me that they would not perform the repair and that I was being forced into the buyback process under a settlement agreement release (sar). Elder Hyundai refused to provide me a loaner vehicle because I was not proceeding with repairs, despite the issue being part of an engine recall. They also refused to give me the repair order report for my records and refused to let me retrieve my personal items from my vehicle unless I paid a diagnostic fee. Hyundai motor America told me I was covered under them for this fee, yet elder Hyundai still refused. Regarding transportation, I was initially told Hyundai does not reimburse turo rentals due to concerns about “fake receipts. ” because of my budget and age, turo was the only rental option I could afford. After escalating, a supervisor approved reimbursement for my turo rentals, but as of today I have not received any reimbursement. I am a school teacher with a two-hour commute each day and I have [xxx] twin toddlers. I had to use rent and bill money to pay for the rentals based on assurances that reimbursement would be processed within a week. I submitted all receipts, but my new case manager claims he has no record of them, further delaying reimbursement. I completed and returned all sar buyback documents on November 15th, yet I have received no update on payment or processing. This entire ordeal has put me at financial risk, including potential job loss and housing instability. Hyundai’s delays and mishandling of this safety-related case have severely impacted my livelihood. I ask that you please review hma’s action information redacted pursuant to the freedom of informa.

While driving my 2017 Hyundai Sonata, the engine suddenly began making a loud knocking noise and the vehicle entered "limp mode" the check engine light was blinking, I took the car to a very close autozone and the check engine light came on with code p1326 (pricture upload files), which is directly related to the known ksds connecting rod bearing defect. This issue is part of Hyundai’s safety recalls and engine warranty extensions. After that, I called Hyundai directly (reference number for that call #xxx). A kind young woman informed me that my car had been through "service campaign 953" and successfully completed a "knock sensor detection system (ksds) software update. " thanks to this, she explained that my car is under the "Hyundai txxi warranty" and that, given the noise I was hearing along with the "p1326" code, it was very likely that my car qualified for a free engine replacement. She then scheduled an appointment for me at the nearest Hyundai dealership for the following morning. After more than two weeks of inspection, the dealer confirmed that the engine has internal damage and needs a complete replacement due to rod bearing failure. This is the exact defect addressed in Hyundai’s safety campaigns. However, Hyundai corporate is refusing to cover the engine replacement because the vehicle exceeded its mileage limit, even though the engine failure is clearly caused by the known safety-related defect. The dealer acknowledged the problem and documented everything, but Hyundai is denying proper safety recall-related coverage. This puts my safety and the safety of others at risk, the vehicle is currently disabled and undrivable at the dealership due to the defect. Hyundai is only offering a buyback or a small cash settlement instead of performing the necessary safety repair. I am filing this complaint for many reasons but mainly because the refusal to replace the defective engine, despite the recall-related code p1326 and confirmed bearing failure. Information redacted pursuant to the freedom of infor.

I am the original owner of a 2017 Hyundai Sonata with the oil consumption defect Hyundai is well aware of. For years I have been adding a quart of oil every thousand miles and had my spark plugs replaced three times in two years now. Why am I not included in the recall so I can have the repairs done free of charge? the dealer wanted me to start having them monitor my oil consumption first which will cost me around seven hundred dollars for something they already know is defective. I submitted repair bills for the spark plugs to Hyundai around a year ago, but they would not reimburse. This is a safety issue as car starts to run badly with fouled plugs.

I have just purchased this vehicle from jones Nissan in savannah, TN September 27, 2025 for my daughter's 18th birthday. I was told the car passed all inspections etc and was sold the car same day. We checked the oil before leaving and oil was good. Within 45 miles we came home and my husband checked the car and the oil was down half quart. We didn't think anything of it and he did complete oil change. Last night my daughter comes in and my husband checks her oil almost 3 quarts low. There are no leaks nothing we can find. This is absolutely absurd this was a car for my 18-yr old daughter to go to college and back. There are no lights that come on to tell you it is low or nothing. This is completely uncalled for and Hyundai needs to replace or correct this issue. This could cause her to be stranded or hurt if this motor was to lock up.

My car is needing an oil change almost every 3 weeks at this point. Mechanics say there is no leak and there may be a recall for gdi engines that are burning oil very fast. This is a reoccurring problem and would love to find out if I can get this recalled like I seen other 2017 Hyundai Sonatas.

We bought the car 9/27 was told the car past the dealer inspections. The cars oil was checked and I am sure it was changed and all prior to us. We drove it home and she has drove it to school. On 10/15 my husband did a routine oil check and it was over 2 qts low. He did a complete oil change and changed the pcv valve and as of yesterday it has used another 1 gt. This car was just bought 8900 and now I am assuming it needs rebuilt or new engine. I would like for this to be reimbursed. This is outrageous. When we reported the prob it had 149000 miles on it and hydunai gives to 150000. I need this issue to be fixed.

To whom it may concern, I have own my vehicle since Jan 2018, which was purchased from the dealership's owner w/less than 10k miles. Maintenance has been performed iaw Hyundai's recommended schedule. However, yesterday, I was informed that my vehicle needed a new engine and other replacements totaling $13,934. 89. This is outrageous. How can a well kept vehicle w/106445 miles, need such replacements? thus your assistance will be greatly appreciated.

The engine shut off on the highway on two different days. Vehicle was going between 65 and 70 mph. The vehicle engine shut down and all the warning lights came on. Every one. The vehicle still moved but nothing inside worked, it ran on battery mode for the 17 miles to the dealership with a maximum speed of 60 mph. The risk was the immediate unresponsiveness of the vehicle and the sudden and immediate reduction in speed and power. It presented itself twice in about 2,000 miles. The dealership charged a 491$ diagnostic and found all the warnings and reset it, not reason for it happening and sent me on my way. Then it happened again. Brought back to the dealership and they tried to say they did another diagnostic and called the tech helpline. It took hours and they still don’t have a definitive answer, wanted to try almost 2k in repairs to see if it would fix the issue without any guarantees it would. Warning lights, all of them came on, cruise control, abs, engine light blinking, steering, literally everything and messages started running through the information center.

I purchased my 2017 from Hyundai motors of America in 2017. I am the only owner. I took the care in for a recall for campaign 953: ecm & cluster update-engine monitoring logic product improvement to have a a knock sensor placed on the engine to monitor the vehicle for signs of engine failure in 2022. The car has been showing signs of engine failure since the knock sensor was placed on the vehicle and Hyundai claimed that the knock sensor was bad and replaced in. Last week while I was driving the car ok the interstate at 70 miles per hour, the engine stopped running completely while driving. The check engine light did not illuminate until after the vehicle’s engine stopped running. The vehicle lost its ability to accelerate while driving. I was almost hit by a semi as I tried to guide the disabled vehicle to the emergency lane. I took the vehicle to one of the Hyundai dealerships for an inspection. The inspection shows engine failure due to internal failure. The knock sensor from campaign 953 failed to detect any engine problems. I called Hyundai motors of America and was given a case number (41539529). Even though the dealer reported to Hyundai motors of America about the engine failure, Hyundai motors of America is refusing to fix the vehicle due to mileage even though there is an extended warranty through campaign 953. This company is a fraud!! the company wants me to pre-approve authorization payment for them to replace my engine at my expense regardless of the recall, and their negligence!! they are placing people lives at risk.

The contact owns a 2017 Hyundai Sonata. The contact stated that while operating the vehicle, there was an abnormal knocking sound coming from the engine compartment with the check engine warning light remaining illuminated. The vehicle was taken to the local mechanic who discovered that there was no oil in the engine, even though the contact had recently added oil. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer and local dealer were notified of the failures. The failure mileage was 109,000.

We are the original owners of this vehicle. Over the past year we have been having to put quart(s) after quart(s) of full synthetic oil into this vehicle. There are no leaks anywhere that the mechanic can find and no burning of oil from the exhaust. We don't drive the vehicle many miles but have to put oil in at least every few weeks. The mechanic stated the last few times we have taken the car in to get looked at that it is a known issue with this make/model. He stated there was nothing he could do and we needed to contact the manufacture. We have tried on numerous occasions to make contact as well as the dealership has as well with no resolve.

The contact owns a 2017 Hyundai Sonata. The contact stated that after receiving oil changes on four occasions, the oil warning light illuminated. The vehicle was taken to an independent mechanic twice, and the contact was informed that the oil pressure sensor was leaking at the connector, and the oil pressure sender or the switch needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was then taken to a dealer after being driven for 1,000 miles, and the oil usage was documented. The contact stated that in 7 days, the engine had consumed one quart of engine oil in 167 miles driven. The vehicle was taken back to the dealer, where a combustion cleaning was performed; however, 4,000 miles later, the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was approximately 92,379.

. Car is using or burning alot of oil. After oil change. It went 2800 miles on the oil change and the cars oil light come on. Checked oil and nothing on the dip stick. Headlights randomly shut off at night. Had the wiring checked and didnt find any issues.

I am constantly seeing my oil light coming on. I have placed at least three quarts of oil in the last month while driving around only 1,200 miles. I took vehicle to mechanic who explained this is known issue with the vehicle I own.

My 2017 Hyundai Sonata limited check engine light came on at approximately 103,000 miles of use. This happened last week. The code it was pointing to was a faulty fuel pressure sensor. Could also be combined with faulty fuel pump, but the primary code indicates the sensor. I will be taking it in to the Hyundai dealership shortly. The main reason I’m reporting this is because of my previous experience owning a 2011 Hyundai santa fe that had to have the engine replaced three times all under warranty. There ended up being a class action lawsuit because of several owners experiencing the same proglem. While this may not be the same case, I am leary of engine problems like this. I take very good care of my cars with regular maintenance, so I’m reporting this just in case others are experiencing the same problem.

What component or system failed or malfunctioned, and is it available for inspection upon request? the engine in my 2017 Hyundai Sonata sport is defective. Oil pressure failed testing, oil contamination was found on the oil pressure sensor and connector, and the vehicle has experienced excessive oil issues. The engine is still in my possession and available for inspection upon request. How was your safety or the safety of others put at risk? the vehicle has gone into limp mode on the highway, which caused a sudden loss of power and created a dangerous situation in traffic. The car also shakes, misfires, and loses power unexpectedly, which could lead to stalling or loss of control at highway speeds. I do not feel safe driving the car. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. Multiple Hyundai dealerships have inspected the car. One confirmed low oil pressure and oil contamination at the sensor. Previous visits dismissed the oil warning and charged me for oil replacement instead of identifying the underlying defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes. The vehicle has been inspected by Hyundai dealers multiple times. I also have two inspection reports from the same dealer just two weeks apart with contradictory findings the first showing no oil issue, the second confirming oil contamination and failed oil pressure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes. The oil warning light and check engine light have both come on. The vehicle has gone into limp mode, and symptoms have included shaking, misfiring, rough idling, and loss of power. These issues began months ago and have continued despite repeated service visits.

I am leasing a 2017 Hyundai Sonata from car city in michigan. In may 2025, the vehicle received a brand-new engine replacement due to previous problems. I picked the car up on [xxx], and on the same day, the vehicle began malfunctioning. It would not accelerate properly, jerked and stalled, and multiple warning lights — including the check engine light — came on immediately. This made the car unsafe to drive. I contacted the dealer, but they told me to wait until Monday to get it looked at, leaving me with a dangerous and unreliable car. The vehicle had already been in the shop for over two months for the engine issue, and I had only driven it for six months beforehand. I believe the repair or replacement engine is defective or was not properly installed. This creates a serious safety hazard. A car that stalls while driving puts everyone at risk. I am filing this complaint so this issue can be investigated and addressed if others are affected. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Engine started making a noise and then the car died and would not start. We were on the highway service road when the car died in the middle of the road. We took the car to the dealership and they confirmed the vehicle engine has seized up. This is covered under warranty. The manufacturer denied the claim because of a sensor recall in August 9, 2018. We purchased this car used on July 11, 2018 and never received the recall notification for this sensor. The manufacturer is refusing to repair the engine that is under warranty.

Purchased the vehicle and immediately noticed a drip in the driveway. I was concerned so I started checking the dip stick. I booked a diagnostic appointment with a Hyundai service center. I wanted to be sure I purchased a quality vehicle. Upon what I thought was a complete diagnostic, a cracked oil pan was discovered. I agreed to purchase and pay out of pocket, everything else had checked out. I was told I could drive while I waited for the pan to come in, service was scheduled. The car never made it back. I continued to check the dipstick but while driving on a very busy interstate, the engine light went on and lost power. I barely managed to get to the breakdown lane. A complete safety hazard. I was towed to the closest garage where the owner suggested he see’s 3-4 of these a week. He would not touch it, have it towed to Hyundai. I paid for another diagnostic and now a flat bed tow. Key Hyundai of salem nh accepted the vehicle. I paid another $498 to have an “engine tear-down” send a detailed finding report to corporate. I called corporate and filled my own case number. I was denied by corporate, I was told I was a subsequent owner. The dealership didn’t match, I’m denied because the engine didn’t seize because of rod issue. Well Hyundai is praying upon consumers. They knowingly initiated the kds recall and installed sensors to place a vehicle in “limp mode” so the rod isn’t the issue and they deny coverage. I paid a private mechanic verify cylinder 3 has low compression. Had the car not gone into “limp mode” the rod bearings would have failed.

Premature rod bearing failure at 126,750. Dealer said there was extended warranty for this failure. Turns out that Hyundai denied this because they say recall 953 was not done. This does not reflect what I show, I show this a service program and probably a notice does not get sent out. I have gotten an estimate for $7848. 50 for engine replace. I do not agree with this decision since it is a know problem with multiple class action lawsuits.

Engine is burning up full tank of oil in a few days there are no oil leaks coming from the car. The car has been expected and worked on by multiple mechanics. The engine lights keeps coming on.

The camshaft position sensor internal rubber plug is faulty and it allows oil to leak into the sensor housing. Ruining the sensor and the brushes and housing. It causes the check engine light to come on the idle races and car takes off on its own. Can’t drive it because it’s to dangerous. Once it takes off then it goes into limp mode and you can’t pull out because of no power. 40000 miles. The internet is full of owners having the same problem.

What component or system failed or malfunctioned, and is it available for inspection upon request?\n' + 'the engine in my 2017 Hyundai Sonata is defective. It burns oil excessively, fouls spark plugs and ignition coils, and causes continuous misfires. The engine is still in my possession and available for inspection. \n' + 'how was your safety or the safety of others put at risk?\n' + 'the engine misfires cause my car to shake violently while driving, lose power unexpectedly, and turn on the check engine light. This creates a risk of stalling or losing control while driving at highway speeds, endangering myself and others. I no longer feel safe driving the car. \n' + '\n' + 'has the problem been reproduced or confirmed by a dealer or independent service center?\n' + 'yes. Multiple independent mechanics have confirmed that the misfires and repeated spark plug/coil failures are caused by the engine itself, not just normal wear. Hyundai dealers acknowledged the excessive oil consumption and advised combustion cleanings, which did not resolve the issue. \n' + '\n' + 'has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?\n' + 'yes. The vehicle has been inspected by multiple Hyundai dealerships (including mcgrath Hyundai) and independent service centers (pep boys, aamco, and others). All noted ongoing oil-related issues and repeated failures tied to the engine. \n' + '\n' + 'were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?\n' + 'yes. The check engine light has come on repeatedly over the last two years. Symptoms include rough idling, heavy shaking, loss of power, and repeated ignition coil and spark plug failures (monthly or more often). The problem began within the first year of ownership and has persisted ever since despite repairs.

All documents are attached as it is many separate incidents that ended knock from motor and minutes later, a piston shooting through the engine block which is what made the car inoperable.

I noticed my oil was pretty much empty at one point. I don't know how long it had been empty but I had been driving the car for a long time. But I usually do my oil changes every 5000 miles so the fact that the oil was empty is definitely not a good sign. I did an oil change and replaced the drain plug in case that was the issue. I checked for leaks and there weren't any. After probably a couple thousand miles, the oil was out again. I took it to a dealership and the guy at the service desk said "I shouldn't tell you this, but a lot of them have that problem. You should get rid of it before the engine fails. " Hyundai knows that it's an issue but they refuse to fix it or do a recall. It consumes oil like crazy and there's even a facebook group called Hyundai oil consumption recall with about 5000 people in it. If the oil in the engine drains to empty, the engine could seize up and put people in danger. No warning lights have come on when the oil has run out.

Engine seized on me, lurched forward, then engine light starting flashing and I could barely accelerate anymore. Had to go very slowly to make it home. My local autoshop says this is very common with Hyundai's and there was a recall for bad engines for this.

Car consuming excessive oil. Oil changes went from lasting 6-7k miles, to less than 4k miles, to less than 2k miles within a year. Checked for leaks, nothing found. Here is the breakdown, I added more oil when the oil lights would flash on. : 12/06/24 full oil change mileage: 80,735 6/11/25 full oil change 86,164 miles 10/6/25 1 qt  89,000 miles 10/10/25 full oil change 90,121 miles 1 qt 11/30/25 91,550 miles 1 qt 12/11/25  92,700 miles Hyundai is aware that this is an ongoing issue - they should legally be required to fix this whether a car has a warranty or not. Bad for the engine and engine replacements aren't cheap.

The engine was eating up oil and failed. I have regularly had to get oil changes within 1000 miles of each other. Kept oil in my car like spare gasoline to top off every 4-7 days. Took my car in immediately when the check engine light came on to which the dealership said I have been negligent in my oil changes. The check engine light never came on prior, and I had an oil change the day before it did come on. It put my safety at risk because the engine could have just burst at any moment, and to my knowledge nothing was wrong since I was regularly putting oil in or getting an oil change. Yes the issue has been confirmed by the dealership. There was no warning other than the low oil light continuously coming on. I took it into the dealership last spring to which they said there was no issue.

Having engine issues with Hyundai Sonata (2017) have taken to dealership for repairs since purchase of vehicle (used) in August 2019. Vehicle available for inspection. Safety of others as well as self by engine failure while refueling, causing driver to be unable to move vehicle. Engine problem confirmed at dealership in April 2025. Issue addressed with Hyundai national consumer affairs to seek adequate replacement of engine and components. On 14 may 2025, request was denied. Check engine lamp illuminated on 1 March 2021 the 1st time, 5 June 2023 for 2nd time and 21 April 2025 for the 3rd and final time.

My car started using a lot of oil,one day it just started jerking and lost speed had to change the spark plugs after that I was constantly putting oil in it and changing the spark plugs every 2 weeks.

The car went into limp mode activated by the knock sensor. Audible knocking noises were emitted. Hyundai dealership replaced knock sensor. Car drove 63 miles before knocking noise repeated and car went into limp mode. Hyundai dealership requested new engine as problem is covered by extended warranty for known issue. It has been declined by corporate office. Car is at dealership and unsafe to operate.

The 2017 Hyundai Sonata 2. 4l excessively consumes oil. I constantly put oil in my car. My fear is that I will have a critical engine failure during commute and will be fully responsible for replacing the engine even though Hyundai motors designed a poorly built engine. Every time I search google about the make and model it is always hundreds of other Hyundai Sonata owners with the same problems and fears that their car will break down or have already had their engine replaced. I would like to see an investigation take place on the 2017 Hyundai Sonata 2. 4l engine. It is poorly designed and consumes more than enough oil in a short amount of time to cause engine failure.

The check engine light light is on now giving code p200a I was driving and the center console shut off and the engine died I had to pull over and start the car again it started but the check engine light light is on now for a p200a I’ve looked it up and everything I can find says there is a recall but my car isn’t in it so what can I do I don’t want to cause a fire or an accident because my car messed up o. Me.

My 2017 Hyundai Sonata se is experiencing symptoms consistent with connecting rod bearing failure covered under Hyundai’s ksds extended warranty program. June 22, 2019: ksds software (campaign 953) installed, qualifying the vehicle for Hyundai’s 15-year/150,000-mile warranty coverage for bearing failures. August 2022: campaign 208 engine recall performed. Hyundai’s record shows Aug 15, 2022, while wright way Hyundai’s service history shows Aug 13, 2022 (discrepancy unresolved). March 2025 (100,238 miles): vehicle went into limp mode with tailpipe smoke and loss of power. It was towed to wright way Hyundai, which kept it for several days but returned it with “no issue found. ” the smoke continued. June 5, 2025 (103,996 miles): oil change performed. August 27, 2025: oil light illuminated, dipstick showed no oil. Vehicle now exhibits severe drivability issues consistent with bearing damage. Hyundai has incorrectly tried to reframe this as an oil-consumption issue and directed me to pay $600 for a combustion chamber cleaning. My issue is not oil consumption — it is a bearing-related failure already covered by warranty. Hyundai’s obligations include a no-cost inspection/diagnosis for connecting rod bearing failure, yet I have been denied that process. Despite repeated written requests, Hyundai continues to attempt phone communication instead of email, even addressing me by the wrong name in correspondence, which suggests reliance on standardized or generic responses. I have exclusively maintained the vehicle at wright way Hyundai, following Hyundai’s service schedule. I am resorting to filing this complaint because after weeks of email correspondence, Hyundai’s corporate agent refuses to help and the manager insists on only calling by phone — which I will not answer out of concern they will attempt to mischaracterize or dismiss my complaint verbally. This failure poses a safety risk because the vehicle has lost power suddenly and requiring restart.
