Driving and engine began to tick, for a couple minutes, then died. Would not restart.
2016 Hyundai Sonata engine complaints
Page 4 of 17: complaints 71 to 100 of 463, newest first, as owners wrote them.
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.
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).
I had knocking in the engine from the auto body shop and my extend warranty told me this is the problem that I have
Engine consumes excessive amount of oil, approximately 5 quarts every 1,000 miles. No leaks found when taken for inspection.
There is an oil problem with this car - my engine light keeps going on, then it backfires, I brought to the dealership and $2,800 later, I still have the same problem. There is no leak that I can see, the oil just disappears. My mechanic said this is a known problem but Hyandai will not get back to me, I have tried several times with no interaction back
My car has 123,000 miles on it, it started with just aircon compressor not working then a week after the engine light started blinking and doesn’t accelerate more than 60 in the interstate then there is a rod knocking in my engine after that.
The vehicle is consuming oil because it’s burning it. The mechanic changes my oil and the same day the oil turns black. I have to constantly check the oil gauge and top up the oil when low. Unsure of the damage this might be doing to the motor.
The engine stopped as I was driving on the road.
I am reporting a serious safety concern involving my 2016 Hyundai Sonata Hybrid, which has experienced multiple hybrid system shutdowns while driving. This includes repeated complete power loss incident on I-90 beginning in June 2022, when my daughter was driving home after her hospital shift. The vehicle displayed a “Hybrid System Warning – Turn Off Engine” message and had to be pushed off the highway and towed. This was the first of several hybrid-related failures that culminated in a full engine replacement under warranty at 82,015 miles — and now, the same hybrid system warning has returned at 127,592 miles, well within Hyundai’s 150,000-mile hybrid warranty. Hyundai is currently denying coverage. I am requesting that the federal safety agency investigate repeated hybrid system faults and warranty denial patterns in Korean-manufactured Sonata Hybrids.
Engine its completely shot won't go past 55 mph showing code p1326 knock senor bull crap. Which is the same reason and shows same symptoms as all the other recall 198 engines but hyundai won't cover my model vehicle because its not "part of the recall" when it should be I still owe 10k on my vehicle hyundai quoted me 10k to replace the engine i shouldn't be paying anything due to the fact that yall consistently have to same problems on all your vehicles.
I am writing to formally request reconsideration of a denied warranty claim regarding my [XXX] son's 2016 Hyundai Sonata, which recently suffered complete engine failure and Hyundai has denied. The vehicle is equipped with the Theta II engine, which is widely known to be associated with engine failure risks and is covered under Hyundai’s extended warranty program. Despite this, my warranty claim was denied due to the fact that two recall-related services were not completed. I would like to respectfully challenge this decision for the following reasons: The engine failure is consistent with the known defects in the Theta II engine, which Hyundai has acknowledged through its extended warranty program and recall campaigns. I was not properly informed of the outstanding recalls or their impact on warranty eligibility. We purchased the vehicle in November 2024 and had not received any notifications of these recalls. Had I been made aware of these recalls I would have taken immediate action but again, I was not ever notified. The failure of the engine is unrelated to any owner negligence and should be covered regardless of recall status, especially under a defect-related extended warranty program. The failure has left my son without a functioning vehicle and facing a costly engine replacement for an issue Hyundai has accepted responsibility for in thousands of similar cases. He started working at [XXX] to begin saving for his first vehicle. He spent $8,000 of his own money and is now devastated by an issue outside of his control. I am requesting a full reconsideration of my claim and repair costs under the extended warranty program. Due to the Engine failure my sons car locked up and died while traveling with passengers. This was a terrifying safety event as my son was stuck in the driving lane with traffic until the car could be towed. Please let me know what additional information you need to review my case. Thank you, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5
Engine failure
While driving my 2016 Hyundai Sonata Hybrid SE (89,000 miles), a “Check Hybrid System” warning appeared on the dashboard, followed by a sudden loss of power. Shortly after, the engine began knocking loudly. A local mechanic scanned the codes and saw engine misfire and hybrid system faults. After clearing the codes, the engine ran worse and the knocking increased significantly. I had to tow the car over 700 miles from Whitehorse, Yukon, to the Anchorage Hyundai dealership in Alaska, which cost me over $5,000. The dealership said they hear engine knocking but refuse further diagnosis unless Hyundai initiates a goodwill assistance case. My car has a rebuilt title, but this issue appears to be similar to other known failures and recalls, such as Campaign 198 / the federal safety agency 20V746000. It is a serious safety issue — I was stranded in the middle of a remote highway. This appears to be a major defect, and Hyundai needs to investigate and support affected customers.
See attached document for complaint.
I had engine issues back in 2021. I had to pay $600 for a part to be installed to fix the problem . The engine failed, the idle was violently lurching forward and would randomly Shut down. Recently the car shut down without warning again. Its scary.
My car on the freeway started knocking. The check engine light came on. The car immediately caught fire. It is at the tow yard now. We just went through the oil consumption testing and the cleaning. I filed a report in November it failed for misfire and we paid to have the top rebuild. The car failed the oil consumption 1000 miles after the cleaning. We were told to continue to drive. We had 4 people in the car. I have the dash cam with the rod knock. The car has a check engine code. Hyundai needs to be held accountable.
Oil consumption issues burning oil no leaks.
While accelerating from a red light, the engine suddenly lost power and the car stalled in the left turn lane in the middle of traffic. We had to have the vehicle towed to a repair shop, where I was informed that the engine had seized or locked up. The mechanic mentioned this type of failure can happen if the engine loses oil pressure, but we received no warning lights (oil, check engine, or otherwise) prior to the failure. The vehicle has always been properly maintained, including an oil change just a few months prior, and it had not been driven much since. This vehicle was purchased for my daughter to travel to and from college safely and reliably. We have taken great care of it, so the sudden and catastrophic failure of the engine (without any prior warning) is both unacceptable and devastating to our family and we have no way to get her back to her college. I’ve now learned that this year, make, and model: 2016 Hyundai Sonata has had numerous complaints and issues related to sudden engine failure and oil system issues. To my knowledge, this issue has not been officially recalled, despite a pattern of numerous similar reports. This kind of failure puts drivers and passengers at serious risk, particularly when it occurs during active driving conditions like what happened to us as we were stranded in the road and it almost caused a vehicle to hit us. As a parent, I entrusted Hyundai with my family’s safety. I am extremely disappointed by what appears to be a systemic issue and . I urge the agency to reconsider investigating these failures and pressure the manufacturer to do the right thing, stand behind their product and support affected customers like us.
I just recently purchased about a month and a half ago. I was on my way to work and it was a thudded knocking noise before my car slowed down and shut off on the highway. I had to get it towed to a nearby restaurant I had a mobile mechanic come by he put it on a scanner code p0014 came up with the engine light on.. When he cut the car on and heard the noise he said my engine has failed.. I haven’t had any prior issues with my car before this date.. He mentioned it’s recalls on the engine I have my VIN doesn’t show it’s a recall but it’s the same issues described happened
Sometimes I see the engine ligth when I drive to long
My vehicles engine gave out on highway 95 . I towed it to the Hyundai dealership after a mechanic friend informed me of the recall with the Sonata Engines. Hyundai is refusing to assist with my engine failure under the recall or my lifetime warranty. They are stating that the recall is voided due to my dipstick size and that my lifetime warranty on the engine is voided due to another safety software recall not being updated before the engine recall; I was not informed by Hyundai of either recall. I am now without a vehicle

The engine they even have a recall on my car engine this have caused no risk this problem have been confirmed by a mechanic haven’t been legally inspected yes the oil light comes on often
I am reporting multiple safety-related problems with my 2016 Hyundai Sonata Sport 2.0 that have become progressively worse and may pose a serious danger. The Electronic Stability Control (ESC) warning light starts blinking during startup, then remains solidly illuminated while driving. This indicates a persistent fault in the stability system. The car also frequently slows down or brakes on its own, without any input from me. This happens especially right after starting the car or while driving in traffic, and has caused multiple near-accidents. These issues first appeared around two years ago, but they used to happen occasionally. Over time, they have become more frequent, and now they occur daily. There is also a grinding or dragging noise when the vehicle starts or moves at low speed, and it often hesitates when trying to accelerate. These symptoms create uncertainty and make the vehicle feel unsafe to operate. Inside the car, the dashboard has severely cracked, with deep, wide splits across the top panel. I’m concerned this could interfere with airbag deployment or reflect light dangerously while driving. On the outside, the paint is peeling off in large chunks, and I’ve noticed the same problem on other Sonatas of this model. This suggests a wider manufacturing issue and raises concerns about long-term durability and corrosion. These problems have not been confirmed by a mechanic yet, but they are consistent, worsening, and clearly pose a safety risk. I have recorded a video that shows the ESC warning and the sound it makes, which I am including for reference.

Extremely well maintained car began burning excessive amounts of oil. Called Hyundai corporate and they said that there is an extended 150,000 mile warranty on the engine and set me up with the Metrowest Hyundai dealership in Framingham, MA to begin oil consumption test procedure. Dealership performed test and I burned almost 2 out of 5.1 quarts in 1,000 miles. There is no reason a well maintained engine, with regular oil changes well within the manufacturer recommended interval and using full synthetic oil, coupled with regular engine maintenance and Techron, plus at least 80% highway miles, should be doing this. Dealership then performed combustion chamber clean as step 2 of process and the entire timing system began failing after that (P0010 and P0011). The car is now at the point of almost catastrophic engine failure and it will cost $6,200 to repair (the value of the car itself). Hyundai corporate then told me I'm actually not covered and that the warranty only covers rod bearing failure. So both they and/or the dealership strung me along, and the car is clearly not made well and Hyundai is not addressing these concerns. I know many people have had these issues with these cars. In my case, trying to get them addressed then destroyed my car.
Hello this is my second time filing for a complaint because the first time I did not receive an email confirmation. On Thursday night (April 4th) I was driving back home, I had just existed the highway and was now on a regular big busy street. I was driving approximately no more than 25 MPH. At the traffic light when it turned red I obviously had my foot on the break. When it had turned green and I tried to accelerate the car would just not simply move. As I said I was on a busy street there was many cars, My partner and I had to safety move the car by foot out of the road to let other cars pass, it was very dangerous for us since it was at night. I'd like to add prior to this the only time I ever had a problem was when I would turned on the car and later try to drive it would start shaking for a minute and then suddenly stop when I parked it and turned it off. Also there was never any engine light or any warning lights on the dashboard, To continue I had to call my dad late at night to help me find what was wrong with the car, obviously since it was at night there was not much to do, but to park the car and leave it there overnight. Next morning he goes and try to see if it turned on, It didn't the car was not running anymore, he called a tow truck for them to take it to a mechanic, In where they said it was an engine problem. The mechanic told my dad it would need a new engine which that can cost a lot. I called in the dealership in where i am financing it and told me if it was a motor problem I would have to pay $7500 to $8000 for a new engine replacement. This is do draining knowing I've had this car for less than TWO MONTHS and already having to pay for a new ENGINE? This was also very dangerous knowing the car never showed a warning light on the dashboard !! I could've been driving on the highway and the car could've stopped in the middle this could've been super dangerous putting my life at risk not knowing the the car had an engine problem.
Driving back home [about a 20 min ride] car has been driving fine, with no lights on dashboard EVER showing , obviously on a red light i had the break, then when it turn green the car would not accelerate at ALL. Car was still on with light and radio working the car would just not accelerate. I was on a busy street so I had to push the vehicle by foot with my partner to get it out of the way. Oil and battery seemed fine, I had to call my dad for help he as well did not find anything. We had no other choice but to leave the car on that street parked. Next morning my dad went to check it out and the car would not turn on AT ALL. He called a towing truck and took it to a mechanic in where he said that it was in fact the engine. When driving and prior to other cars I've driven the car there was never a warning sign what so ever this came out unexpectedly, putting my partner and I at risk in a busy street having to move the vehicle by foot.
