general problems of the 2017 Hyundai Sonata - part 1

Sun roof flew off while driving, the metal framing was twisted and dent. Sun roof was closed at the time. Pictures were sent to insurance company but no one has looked at it yet. No warning. Sun roof was working properly.

Here is your updated review with that included: ? I am very disappointed with Hyundai motor America and the service I received at Hyundai of renton. I own a 2017 Hyundai Sonata and received a letter about a required software update and ignition cylinder protector due to known theft issues. I went to the renton dealer for the recall service. They performed the software update and were supposed to install the ignition cylinder protector. Unfortunately, my car was later stolen because of this exact issue. The ignition was damaged during the theft, and I had to replace it myself just so I could drive the car. When I returned to the dealer, they refused to install the ignition cylinder protector, saying the ignition was broken. It was broken because of the theft — which happened due to Hyundai’s known defect. After the recall software update, my key fob also stopped working properly. I went back to the dealership, and they refused to fix or properly reprogram my key fob. On top of that, the service manager, john, was very rude and unprofessional. This has been the worst experience I’ve had with a vehicle and a dealership. Because of this situation. Very disappointed.

This car is becoming more of a headache than it’s worth. Turned the car on, my car started shaking and my check engine light came on. Then I got this message “a possible condition with your engine control system has been detected on a 2017 Hyundai Sonata”.

My vehicle has a documented excessive oil?consumption defect. After a 1,000?mile oil?consumption test performed by a Hyundai dealership, the engine was found to have consumed 2. 8 quarts of oil, which is far above normal and poses a safety risk. The dealer referenced TSB 23?em?008h and recommended a chamber cleaning but could not guarantee it would resolve the issue. Hyundai motor America declined to cover the repair and refused to escalate my case. This level of oil consumption is consistent with known theta ii engine defects that have led to engine seizure, stalling, and fire in other vehicles. I am reporting this as a safety concern due to the risk of sudden engine failure while driving.

The vehicle’s dashboard continuously displays a “hood open” warning even though the hood is fully closed and securely latched. The hood has been physically inspected and confirmed to be closed, yet the warning persists. The issue appears to be related to a faulty hood latch sensor or switch, which is part of the hood latch assembly. The warning is inaccurate and does not reflect the actual condition of the hood. I am requesting that NHTSA review this issue for potential investigation, as it may represent a defect in the hood latch sensor system on the 2017 Hyundai Sonata that could affect multiple vehicles and pose a safety risk.

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.

My Hyundai consumes oil and I have to put oil in it every two weeks! also my ignition coils has had to be changed 4 times. Also check engine light just came on code saying catalytic converter or oxygen sensor changed oxygen sensor a couple months ago. I purchased it brand new and as soon as I got over 100,000 miles nothing has been going good since then please help also my paint on the top of the car is starting to peel. Will never buy a Hyundai again.

Steering wheel warning light comes on traction control light comes on. Steering becomes difficult.

1. Sunroof disengaged from car. Yes 2. Glass falling from car. Glass could have landed inside car, killing or injuring driver. Glass could have landed on any car behind the Sonata killing or injuring occupants in that car. 3. Unknown 4. No 5. No.

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.

My car is burning a lot of oil to the point I have no oil in my car and that’s bad.

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.

Paint peeling on hood and roof.

The contact was a death investigator calling on behalf of the owner of a 2017 Hyundai Sonata. The contact stated while he was driving at an undisclosed speed, the front of the vehicle crashed into the front end of another vehicle. The events leading to the crash was unknown. The air bags was deployed. The owner of the 2017 Hyundai senata was pronounced deceased at the scene; the cause was presumed to have been caused by the wheel hub dislodging. The death investigator arrived at the scene and discovered the wheel hub in the back of the neck of the driver possibly leading to the fatality. The other vehicle involved in the crash was able to drive off the scene. No further information was available on the other vehicle in the crash. A police report was filed. The vehicle was destroyed. The manufacturer was not notified of the failure. The failure mileage was unknown.

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.

Literally for years I have been taking my car in to rick case Hyundai with the complaint of smelling gas even when the car was parked for long periods. Each time they said they fixed with different items. Gas cap, a part on the catalytic converter, etc. The problem never resolved but I noticed it only happened when the tank was more than half full. I got a video of gas dripping out underneath and took the car to rick case and gave them the video. My car has been there ten days because they first tried to say it was a seal on the fuel pump. This time I said that seems unlikely cause that only happens when tank is full and persists even after car is parked many hours. Now they report they found a pinhole leak in the gas tank. I will upload the video if this form allows. This does not appear to be a pinhole leak to me. I first noticed this around 2019. Unfortunately the video is mp4 and I cannot upload it.

My trunk will not unlatch and open. Trunk opening buttons are functional, however the trunk will not open.

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.

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.

This is the seventh occurrence of complete loss of power while driving on the interstate. The hybrid system warning activated, followed by the engine shutting down, and all dashboard lights illuminated with alerts indicating "shut off engine/hev. " an 18 wheeler was pulling out from the shoulder as I was losing power and barely missed getting crushed. The former problems have all been at interstate speeds with similar accident avoided. The service history clearly demonstrates that Hyundai has repeatedly attempted to address this issue by replacing numerous critical components, including the engine, transmission, knock sensor, battery (three times), integrated brake actuation system, and Smart cruise control, among others. Despite these extensive repairs, the problem persists. On this latest occasion, less than 4,000 miles and four months since the last major incident, the dealership has proposed replacing the intake manifold, egr valve, hsg belt, and spark plugs. The belt was changed less than 20k miles ago. And I believe the spark plugs were as well. Each time my vehicle experiences this issue, it is out of commission for weeks or even months at a time, causing significant inconvenience and raising serious safety concerns. I no longer trust this vehicle and I don't believe the many recalls have successfully addressed the root cause of issues with the 2017 hybrids.

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 santa hybrid limited it all started with 11 icons appeared on the dash took it to Hyundai dealership gainesville to be fixed in July of 2024 dropped it off Wednesday they emailed me with a price of 1563. 70 I okay it to be fixed.

Key is stuck in ignition and won't come out. Key comes out maybe a half inch but won't turn either way. Steering wheel is not in locked position.

My car has cut off in the middle of the highway and street. I feel vibration under my seat and I was unable to start my vehicle. Hyundai repaired my engine and I am still having the same issues. The car feels like it’s slowing down before is completely stops.

On 03/16/2024; while driving on I-90 the vehicle at approx 60-65 miles per hr, suddenly stopped, and had to be towed to matthews Hyundai of schenectady.

I can’t drive my car on the highway cause then it will shut off and say hev system error and I have to shut my car off turn it back on then erase the code with my diagnostic tool. My oil light keeps popping up and whenever I slightly press on the gas pedal or go up a steep hill, it starts to rattle, been noticing my oil burns out fast and I have to replace it when it gets low.

Hello! I bought a car in the USA, I live in another country. Errors that appear in the car are similar to these: [xxx] ?rror appears then, the cogd I give more gas and let go of the pedal. When the engine is heated at different speeds. The scanner showed these errors: p1326 ignition control module - combustion quality input signal; u0293 lost communication with hybrid powertrain control module; u1004; b2aaa. But the electricians do not know what the reason is and no one can help. So I go for one year with an error ((( please help! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I heard a pop noise. My car started to smoke a few seconds later full fire. The whole dashboard radio was gone. Burned. No light indicating there was a problem. Car was not running hot.

Shark fin antenna came off.

About 3 weeks ago I had just left my house, battery fully charged and gas tank full. I was coming down a hill to a stop sign and started braking. Suddenly the car seemed to lose power and essentially stopped moving. There was an error on the dash saying "hybrid system failure". There was barely able enough power to slowly pull the car over to the side of the road. I turned off the car and checked the battery in the trunk - I didn't see any obvious concerns. My husband got there 10 minutes later and we tried turning the car on again. It came on fine but there was an engine warning light. We were able to drive it without difficulty back to my house. I was unable to get a timely appointment at my local Hyundai dealer, so a couple days later my husband drove it to a local garage to see if they could figure out what the problem was. When he turned the car on again the engine light was no longer on. However, at the garage they were able to pull up a history of the car alerts and it confirmed that it said hybrid system failure. I have done some research online and it sounds like there was a recall on Hyundai Sonatas hybrids for 2017 but I did not see a recall for the plug-in version of the hybrid. I searched online, however, and there were many other owners of Hyundai Sonata plug-in hybrids that reported the same incident. I am hoping that a recall gets is issued for the plug-in hybrid as well so that more owners don't have the same problem. If I had been driving on the highway at 65 mph in a middle lane and my engine suddenly lost power it could have been fatal. Oh - one other recent problem I had that I'm not sure is related is that my car recently started losing electric miles very quickly. From the time it was purchased until a few months ago, it was losing plug-in miles at about 1 mi per year (I. E. Each year a fully charged battery gave me 1 mile less). Then about 6 months ago it started losing electric miles very quickly - about 1/mo. Dealer said it was normal aging.

In may, the engine completely failed as I was driving on the freeway, without cause. It had to be towed to the dealership where luckily the engine was replaced under warranty. Less than 6 months later, the hev and cel warning lights came on as I was commuting to work via highway. The car was very low powered, hard to accelerate, and immediately decelerated whenever I started to let off the gas pedal. It struggled to go at or above 60-65 mph. The freeway speed was 70 mph and it was a safety risk for the car to power down. Dublin Hyundai could not replicate the problem, simply recharged the battery and said I was good to go. Less than 1 week later, the exact same thing happened as I started on a road trip. I had to return the car home and get it towed to stockton Hyundai for diagnosis. This is car is only 6 years old, has been routinely maintained, and just hit 100k miles, for which Hyundai is denying any repair assistance even though there is a lifetime hybrid battery warranty.

My engine oil consumption is more. I have driven 70 miles the oil comes from full to low level.

I first experienced hev hybrid system issue back in 2022. I took my Sonata to the dealership which they had over a month to try to fix the problem which they did for the time. Now a year later I’m back with the same issues and the dealer basically saying they can’t see my car for a month then don’t know how long it’s going to take to fix the issues if the even. Nobody can really tell me what’s wrong with my car. This the second time it’s been a safety hazard while driving on the interstate and the system malfunctions causing a hazard to me and drivers around me because the vehicle has basically cuts off rapidly slowing the vehicle down.

This issue has happened twice in one month on my Hyundai Sonata hybrid that I’ve had for less than 3 years. It is a 2017 model. While driving on the interstate, the car will stop accelerating and all warning lights will come on along with “check hybrid engine. Turn off engine”. The dealership has yet to find out the problem and cannot tell me what the issue is both times I’ve brought it in (it’s had ti be towed both times). I cannot afford to keep paying for repairs on an almost new car along with the safety concerns of driving it. I am attaching pictures of both times it happened- noting that it is the same warning each time. It looks like multiple owners are having this issue and none has yet to be resolved.

Hev light comes on and the car starts slowing down & beeping. Unsure what the issue is but this started once the car had more than 100k miles on it.
