2016 Hyundai Sonata complaints

The shark fin antennae on top of the vehicle was ripped off in a car wash; the antennae serves to transmit radio/GPS/data to & from the vehicle which will cease to function if it the cover is removed and components damaged. Hyundai description: The shark fin antenna will receive AM, FM broadcast signals and transmit data Multiple Hyundai dealers have been contacted for quotes on replacing the antennae which they claim will cost $1500+ since the top of the roof must be removed and electronics/circuit board/cables must be replaced; it appears to be a common issue with these shark fins according to the dealers and online research. The GPS and data transfer could be a major safety factor depending on the systems affected. These shark fins need to be replaced with a more resilient system. Owners are unable to 'store' the antennae when taking it to the car wash as it is not removable or retractable. It is a design flaw. I've read that many have lost them simply driving the vehicle --not agitated using a car wash.

Subject: Excessive Engine Oil Consumption – 2016 Hyundai Sonata I am reporting an ongoing and excessive engine oil consumption issue with my 2016 Hyundai Sonata that I believe may represent a safety defect or other significant reliability concern. The engine is burning oil at a rate far beyond normal expectations (requiring frequent top-off well below recommended mileage intervals), resulting in dangerously low oil levels while driving. I have maintained the vehicle per manufacturer recommendations and documented oil add-ins and dealer visits, but the problem has worsened over time. Despite presenting this problem to my Hyundai dealership, they have declined to authorize engine cleaning or further corrective action due to the mileage. I am struggling with high oil consumption and potential risk of engine failure while driving. This issue is not unique to my vehicle — numerous similar complaints exist in Hyundai forums and in other owners’ submitted complaints (e.g., reports of more than 1 quart consumed every ~500–1,000 miles and sequences of denied repairs) which suggests a broader pattern of oil consumption failures for this model year. Auto Safety +1 I believe this may represent a safety defect because loss of engine oil can lead to engine seizure or failure without warning, increasing the risk of a crash or injury. Please review this complaint, add it to the NHTSA vehicle database, and contact me if further information is needed.

I am filing a complaint against Hyundai Motor America regarding denial of defect coverage for my 2016 Hyundai Sonata (VIN: [XXX] ). The vehicle is experiencing excessive oil consumption and triggered diagnostic code P1326. The dealer confirmed only one quart of oil remained in the engine and noted a valve cover gasket leak. Hyundai’s Tech Line instructed a gasket replacement and oil consumption test, but Hyundai corporate formally declined coverage, citing mileage and second-owner status. This is not a routine warranty claim but a defect claim. Oil consumption defects in Hyundai Theta engines are well-documented and have been subject to recalls, Technical Service Bulletins, and class actions. Defect coverage should not be limited to first owners. I am requesting reimbursement for the valve cover gasket repair, acknowledgment of the oil consumption defect, and corrective action to ensure Hyundai honors defect-related coverage fairly.

My 2016 Hyundai Sonata experienced a sudden engine failure while in operation with no prior warning lights or symptoms. The engine seized unexpectedly, creating a safety risk. This failure appears consistent with known engine defects affecting Hyundai Sonata vehicles of this model year. Hyundai Motor America denied my claim without addressing these known defect patterns.

Oil pressure sensor failure caused oil to leak into the injector harness damaging components and engine shutdown. Because this was a sudden engine shutdown and safety-related loss of motive power caused by an oil pressure sensor failure this presents a safety risk

Vehicle stalled while driving

On November 10, 2025, my 2016 Hyundai Sonata Hybrid (VIN [XXX] , approximately 150,000 miles) experienced a sudden loss of power while I was turning right and accelerating into traffic. The vehicle immediately entered limp mode with flashing warning lights and audible alerts. The vehicle lost normal propulsion and could not accelerate properly, creating a dangerous situation as it was blocking a traffic lane. I was forced to limp the vehicle into a nearby parking lot to get out of traffic. The vehicle was not safely drivable afterward and was towed home. A few days later, the vehicle was towed to Murdoch Hyundai in Lindon, Utah, for diagnosis. The vehicle was found to have diagnostic trouble code P1326, which Hyundai identifies as activation of the Knock Sensor Detection System (KSDS) related to connecting-rod bearing wear. This condition is part of Hyundai’s known engine defect and safety recall/warranty extension programs. During inspection, the dealer observed that the valvetrain did not show signs of neglect or sludge, which is inconsistent with oil starvation or severe maintenance neglect. This further supports that the failure is consistent with the known connecting-rod bearing defect addressed by Hyundai’s KSDS safety recall, rather than a maintenance-related issue. This is a safety issue because sudden loss of propulsion or reduced power while entering traffic creates a high risk of collision. Hyundai customer care has been unwilling to open a new case number or escal

My 2016 Hyundai Sonata with the DOHC GDI Theta-II engine is experiencing severe engine oil consumption consistent with Hyundai's known TXXI/TXXC extended warranty defect. The oil pressure warning has flashed while driving or braking, the engine runs rough when slowing down, engine has made knocking noises, and there is smoke/vapor with a burnt oil smell when removing the oil cap after driving. The oil level drops rapidly between changes despite proper maintenance. This issue poses a risk of engine failure, stalling, or fire while driving. I have maintained the vehicle on time with all oil change receipts. A Hyundai dealership refused to perform the required warranty diagnostics even though this issue falls under Hyundai's extended warranty for Theta-II engines. This is a serious safety concern, and no corrective action has been taken.

My Hyundai is experiencing severe and continuous engine oil consumption that creates a safety risk. The vehicle loses a significant amount of oil within 1,000–1,500 miles, sometimes showing almost no oil on the dipstick despite recent oil changes. There are no external leaks, no burning smell, and no visible oil under the car. The cause remains UNKNOWN, but it appears to be internal engine burning or a manufacturing defect. I have taken the vehicle to the Hyundai dealer multiple times. They performed oil consumption tests but either reported “normal results” or did not provide clear explanations. The issue continues exactly the same. I also contacted Hyundai corporate, but no meaningful assistance or goodwill support was provided. The dealer acknowledges no leaks but still refuses to repair or replace the engine. This problem is dangerous because the oil level drops without warning lights or error codes. If I do not manually check the dipstick, the engine could run dry and seize while driving. Sudden engine failure on highways or in traffic can cause accidents. I now have to frequently top up oil just to keep the engine alive. I have maintained the vehicle properly and completed all requested tests. The cause is still UNKNOWN, but based on similar Hyundai cases, it may involve piston rings, valve seals, or internal engine wear. Many Hyundai owners report the same issue, suggesting a broader defect. The dealer’s only advice is to “keep monitoring oil,” which is not a safe long

Car has been consuming oil fast since around 75,000 miles. Car is under 100,000 miles and I have been told by an independent shop that it basically has piston ring failure which means engine failure.

The vehicle is going through oil very quicky. No leaks no burning.

This car burned oil like crazy from the start. We kept the oil changed regularly, had to change spark plugs weekly and add a quart or more of oil each week in between oil changes. One day whole stopped at a red light the engine started knocking for no reason. Once diagnosed it turned out that it had spun a rod bearing. These engines need to be recalled before someone ends up in a fatal accident. This car was driven daily on a major interstate thankfully the issue happened at a red light, but has left me with a car note and a non drivable car. What’s it gonna take to get these engines recalled and replaced?

My 2016 Hyundai Sonata (VIN: [XXX] ) had its engine replaced under recall campaign 20V746000 in March / April 2024 at Hyundai of Round Rock, TX. In October 2025, less than 18 months later and at 97,000 miles, the replacement engine failed again. Hyundai has refused further repair, citing an expired recall warranty. This raises serious safety and reliability concerns, as a recall engine should not fail this soon. Engine failure while driving could result in a stall or crash risk. Please investigate whether Hyundai’s recall replacement engines are defective and if extended coverage is warranted for affected consumers.

Engine issue - but no recalls there have been hundreds of this same car yr and model with engine issues out of the blue

The vehicle experienced an engine and power train failure while driving on the highway, resulting in sudden loss of power. The electrical system also failed after the dealer visit, causing the battery to die every morning. Yes, the vehicle is available for inspection upon request. My car suddenly lost power on the highway and would not accelerate, forcing me to pull over on the shoulder with traffic moving around me. This created a serious risk of a rear-end collision or crash. Additionally, after the dealer visit, the electrical system began failing and the vehicle has been completely dead every morning, leaving me stranded with a child and unable to reliably start the car. The problem has not been reproduced because the check engine code cleared itself after the incident; however, the symptoms absolutely remain. The dealer refused to diagnose the loss-of-power event because the code was cleared, and they returned the vehicle to me with a dead battery. The electrical issue (car dying every morning) has been happening consistently since the dealer visit. The vehicle was taken to a Hyundai dealership immediately after the incident, but they refused to diagnose the loss of power due to the code being cleared. A mobile mechanic scanned the code at my home before the tow, but the code disappeared afterward. The electrical failure began after the dealer visit and has not been properly inspected by Hyundai. Yes. While driving on the highway, the check engine light came on and the c

On September 25, 2023, I was involved in a motor vehicle collision while driving my Hyundai Sonata 2016, during which the front driver-side airbag failed to deploy despite the impact being significant enough to cause injury. This non-deployment represents a malfunction of the airbag system, including its sensors and deployment components, and aligns with issues already reported in class-action complaints involving Hyundai vehicles, making my case further evidence that an airbag defect exists. Because the vehicle was declared a total loss by my insurance company and later sold at auction, the physical component is no longer in my possession now; however, I retain documentation on accident-related records that clearly show the airbag did not deploy. The failure of this critical safety system placed my safety at direct risk because the protective barrier intended to reduce impact forces was absent, resulting in greater injury than would reasonably be expected had the system functioned properly. The problem has not been reproduced yet because the vehicle was transferred to insurance immediately after the incident and was not repairable. But working with accident reconstruction engineers on this matter. Prior to the crash, the vehicle displayed no warning lights, SRS messages, or other symptoms indicating an issue with the airbag system, and at no time before the collision was I alerted to any malfunction that would have suggested the system would fail at the moment it was most ne

While driving, my 2016 Hyundai Sonata’s engine suddenly started knocking loudly. I stopped immediately and found the engine oil was very low without any prior warning. After adding oil, the engine still runs but with possible internal damage. This could have caused the engine to seize while driving. There were no warning lights or leaks before this happened.

Sudden engine failure. Compression issue, car has only 63,000 miles.

High engine oil consumption 2 qts every 1k miles.

Car had oil in the electrode of spark plug. Total engine failure

At 70712 miles cylinder 4 suffered a catastrophic internal failure. The vehicle also had excessive oil consumption and the dealer just told us to keep adding oil as there was nothing they could do. The vehicle must have had a manufacturing defect.

The problem with my vehicle is a failure of internal engine components, specifically a known defect in the piston rings of the Hyundai Theta II engine. This failure causes excessive oil consumption, which is burned internally. The internal engine components have failed, leading to a widely documented defect in the Hyundai Theta II engine. The primary symptom, which began to get serious around 80,000 miles, is the constant need to add oil to the engine every two weeks. If I do not do this, the low oil warning light illuminates on the dashboard, serving as a continuous alert of the problem. This failure was officially confirmed by an authorized Hyundai dealership. About two weeks ago, they first documented that there were no external leaks on the vehicle. When I returned because the oil had been consumed again, they performed a new diagnostic, for which I paid over $300, that confirmed the engine is burning oil internally. The dealership, acting as the manufacturer's representative, is the only entity that has formally inspected the vehicle. The situation places my safety and the safety of others at serious risk. First, the oil consumption can lead to a sudden and catastrophic engine failure, resulting in a loss of power and control of the vehicle while in transit. More alarmingly, the guidance I received from Hyundai staff was to simply "wait for the engine to stop working or start making a lot of noise." As someone who depends on the car for a daily commute, following this da

Was driving on the interstate, and took the exit I needed. Upon exiting before coming up to stop light, noticed check engine light flashing, and couldn't accelerate. RPMS were bouncing when I tried to accelerate. Pulled off onto side of road, called mechanically inclined friend who came with an obd2 sensor, and it was showing a P132600 code for Knock signal range performance, with an audible knocking sound, and engine vibration while on in idle. Got the code cleared so we could drive the car the 3 miles I needed to go to get to where I was going, 2 miles in, the engine light came back on and vehicle went back into limp mode. Called AAA and got the car to an in network mechanic shop for Carvana, whom i bought the car through a month prior. Proceeded to do an oil sample test and found it to be full of metal shavings. Said engine would need to be fully replaced. Vehicle is currently still at mechanic until SilverRock gets the claim and will see if the engine replacement is covered under warranty.

I am submitting this complaint as a follow-up to my prior NHTSA complaint regarding the defective passenger seat Occupant Classification Sensor (OCS) in the 2016 Hyundai Sonata. Previous Tracking Number: 11689976 Since my initial submission, I have prepared a detailed technical and comparative report, which I am attaching here. The report documents how Hyundai’s repair policy for the OCS creates excessive repair costs (over $3,600 for a single sensor failure) and forces consumers to operate vehicles with compromised safety systems, in violation of the intent of FMVSS 208. The attached report provides: • Technical analysis of the OCS design and failure mode • Cost comparison with other manufacturers (Toyota, Honda, Ford, BMW, Mercedes-Benz) • Legal and consumer protection implications, including potential violations of the Texas Deceptive Trade Practices Act • Supporting exhibits (service estimate and parts documentation) I respectfully request that NHTSA review this additional evidence in connection with my prior complaint and consider appropriate regulatory or enforcement actions. Thank you for your attention.

The problem originates from a single faulty passenger seat airbag sensor, but Hyundai requires replacement of the entire seat cushion module, quoted at approximately $3,200 for the part alone and around $4,000 total repair cost. This creates the impression that a single failed sensor affects the entire airbag system. I was not provided with a definitive answer as to whether this fault impacts the driver airbag, which leaves a critical safety uncertainty. By designing the sensor as an inseparable, non-serviceable part of the cushion module, Hyundai forces consumers into an unreasonable expense. This situation puts drivers in the position of either paying thousands of dollars or risking driving with potentially compromised airbag safety. I strongly believe this constitutes a serious safety defect and should be subject to recall.

The contact owns a 2016 Hyundai Sonata. The contact stated that while driving 10 MPH, the Forward Collision Avoidance: Automatic Emergency Braking system engaged abruptly while there was no other vehicle or object near the vehicle, which nearly caused another vehicle to rear-end the vehicle. The contact pulled over to the side of the road. The contact was able to continue driving. The dealer was notified of the failure, and an appointment was scheduled for diagnostic testing. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 111,000.

Pushed acceleration at traffic light to cross and turn into neighborhood, car started beeping frantically, 'check hev system' flashed on dash as well as 'turn off engine' while car decelerated to 1-3 mph. Battery meter bar on left side of dash completely depleted showing no battery power supply at all. Turned vehicle off for a few minutes then restarted. Put the vehicle in drive gear and same warnings appear, car doesn't even accelerate when gas pedal is pressed fully, stays at 1-3 mph crawl. Vehicle stalls out after 30 seconds, vehicle turns on but cannot start.

Engine failure and car burning oil very fast causing other things to go wrong like piston ring and spark plugs.

I was going down the highway and noticed a weird sound and when off the highway it just shut down on me thank God I was able to pull in a median and I could not drive or start it. No other warning signs. I had it towed to a mechanic and they told me the engine was blown and he wouldn’t touch it.

As I turn the corner from home my car started to shake vigorously so I turned into the alley which leads back to my home the check engine light came on. I was able to drive into the garage. So I went to a mechanic who has serviced all my previous cars and he showed me that the car is burning too much oil that was effecting the performance of the engine making it drive sluggish I was also told at the oil changing company in numerous occasions that the sonatas burn oil.

The engine began knocking on us, towed to dealership. Safety concern was dying on the highway with other cars around. The dealer said it needs a new engine. Not sure there were any indications of failure or not. Some records indicate in order for Hyundai to warranty, this car needed to have had campaign 953 KSDS installed prior. Some records such as the TG3 TXXI warranty state that in April 2022, the KSDS campaign update was no longer required for the Hyundai Theta II engine warranty. owner did not perform KSDS 953, based on not receiving the information. Hyundai is currently denying warranty, but if TG3 TXXI is correct, the dealer has yet to fully inspect, and the fact remains that in April 2022 the Campaign 953 is no longer a prerequisite. I dont feel like I should be denied assistance. Please help.

My check engine light came on and my car went into “limp mode” and wouldn’t go above 30 mph. It also kept blowing hot air through the vents and the coolant level thermometer kept raising.

In April 2025, my 2016 Hyundai Sonata 2.4L began making a knocking noise while driving. There were no warning lights or error messages on the dashboard, so I was confused about what was wrong and assumed it might be a minor issue related to the axle, which I had repaired in the past. I brought it to a local mechanic, who informed me the engine noise was concerning and mentioned this model was known to have engine-related recalls. Upon researching, I discovered my vehicle had an outstanding recall for the exact issue (connecting rod bearing wear leading to potential engine seizure), but it had expired due to the age of the vehicle. The car was brought into the dealership on April 30, 2025, and has remained there ever since with a completely failed engine. I was told by Hyundai corporate that they would not offer goodwill assistance due to the recall technically expiring. However, I never received any notification about this recall and had no idea it existed. The engine failure has left me without a vehicle for over three months. I cannot afford the $10,000 replacement cost quoted to me. My Sonata only has approximately 145,000 miles, and this engine failure puts my safety and financial situation at risk. I believe this is directly connected to the original recall defect and should have been addressed regardless of the expiration date, especially since the failure occurred from the same root cause. It has been inspected by the Jacksonville Key Hyundai dealership (where it is lo

But I have heard of numerous 2015-2016 models having the same issue. This car barley had 110k miles on it before the engine failure. These vehicles are not safe and there needs to be something done. It is currently being looked at by delorship. Im hoping for the best.

The contact owns a 2016 Hyundai Sonata. The contact stated while driving 5 MPH and making a turn into a parking lot, the steering wheel seized, and the vehicle came to a stop. The contact was able to push the vehicle to a parking space with assistance. The vehicle was then pushed on to a tow truck and was towed to a Cadillac dealer but was not repaired. The vehicle was then towed to Goose Auto Repair, where it was diagnosed and determined that the front driver's side wheel hub had fractured, causing the wheel to separate from the vehicle. The vehicle was repaired. An unknown dealer was notified of the failure. The manufacturer was notified of the failure and a case was filed; however, no assistance was provided. The failure mileage was approximately 144,000.

WARNING LIGHT ON DASH JUST WENT ON

While driving on the highway, experienced loss of power and flashing check engine light, subsequently causing engine knock and engine failure. This situation could have caused an accident and put myself and others at risk. It is understood the manufacturer has recalled more than one million vehicles due to engine failure and is working with NHTSA to address the issue. In communication with the manufacturer to inspect the damage and resolve the issue.

Rod bearing failed at highway speeds, loss of power and flashing check engine light only after engine failure. This could have caused an accident putting myself and others at risk of bodily damage had I not been able to pull off of the freeway. Engine knock/rattle, eventually leading to catastrophic engine failure. This has been confirmed by a third party trusted and certified technician at an independent shop. Currently in the process of having the damage inspected by the manufacturer.

Driving and engine began to tick, for a couple minutes, then died. Would not restart.

The vehicle is burning oil, so I had a Hyundai dealer (Brandfon Hyundai New haven, CT) start an oil consumption test. At 1,000 miles the vehicle has no oil. Therefore, the engine can seize and shutdown without warning, which could cause serious injury or accident. Hyundai declined an engine cleaning, which the dealership indicated doesn't work anyway. The next step is engine replacement. However, the dealership won't return my calls. This is a common engine problem with older Hyundai's.

This vehicle has a faulty engine design which results in extreme over-consumption of oil. After an oil change, the engine will typically empty in less than a month, which is beyond a reasonable level of oil consumption. Side effects of this include other parts of the engine wearing down quicker, including the spark plugs, which cause engine misfires. Ultimately, this vehicle's engine design causes financial hardship to it's owners and poses a potential safety risk to those who drive in it. I believe Hyundai should do a recall to fix this faulty engine (with an engine replacement if necessary).
