general problems of the 2016 Hyundai Sonata - part 2

What component or system failed or malfunctioned, and is it available for inspection upon request? engine how was your safety or the safety of others put at risk? I was driving 60 mph down a busy highway when I lost the ability to accelerate—putting myself and others at risk while trying to get off the road to a safe location. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? yes. A mechanic that has been in our area for decades. Were there any warning lamps, messages, or other symptoms of the problem before the failure, and when did they first appear? no.

My car burns through approximately 1qt of oil every 500 miles or less. There is a known oil consumption issue and I have left multiple messages with key Hyundai of milford CT and do not receive a call back. Additionally today I was driving 25mph and my car was reading 4000rpm and then completely locked and shut down I was stuck in the middle of the road.

My vehicle had the following symptoms: 1. Alternating between sluggish acceleration/handling and rough acceleration with the vehicle lurching forward at times 2. Check engine light with error code p00010 3. Occurred frequently over a one month period (5+ times) this was unsafe as the car could not properly accelerate and would lurch forward at intersections. This could easily have led to a crash. We limited driving. This issue was observed at the dealer where I repaired issue. The issue is exactly the same as the issue described in the recall for Hyundai Sonata 2015 under sb-10058136-4434 and was resolved by replacement of the e-cvvt seal as described. This issue is ridiculous for me to deal with and put my family as risk given it a known issue for Hyundai in their other vehicles.

Been fighting with Hyundai for quite sometime to have engine repaired due to excessive oil consumption and other issues no matter what you take it they state it’s normal for you to apparently run out of oil before oil change is due. These engine are pure junk and they go out with any warning whatsoever forcing customers to foot the bill for a new engine. They absolutely do not care. I highly recommend any does not purchase Hyundai or kia. Now that my engine finally went out they expect me to pay over 9000 for a new one when I repeatedly told them my concerns ahead of time trying to avoid this.

Oil consumption issues burning oil no leaks.

The contact owns a 2016 Hyundai Sonata. The contact stated while reversing, the vehicle was shaking abnormally. The contact stated that the check engine warning light illuminated, and engine oil was added to the engine. The contact stated that the failure was like NHTSA campaign number: 20v746000 (engine). The vehicle was taken to the local dealer, where an oil consumption test was performed, and it was determined that additional testing was needed, and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was unknown.

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.

I was driving a 2016 Hyundai Sonata on a mountain highway and it started to run rough and lose power dramatically when accelerating. A dangerous situation on a steep curvy highway that has many one lane sections. Shortly thereafter a dash light came on. There was no warnings or dash lights or symptoms prior to this incident. I took the vehicle to a mechanic and ran the code. It said there was a misfire in cylinder 3. Replaced the ignition coil and spark plug for cylinder 3 and it did not fix the problem. The mechanic then pulled the motor to check the valves. Valve 3 was burnt, had a hole and stuck open. The car had approximately 75,180 miles. Well within the warranty time frame of 10yrs or 100,000 miles for an original purchaser. The mechanic had the valve machined, and replaced the head gasket and reassembled the the motor. I picked the car up and drove it home. Within 3 days I noticed an oil leak under neath the car where the engine bay is. I took the car back to the mechanic and he diagnosed a hairline crack in the oil pan. After some research I came across a letter from NHTSA on a defect investigation of Hyundai/kia oil drain pan assemblies. This is exactly what happened to my car! I have paid 3500. 00 to fix a car that has less than 76,000 miles. Hyundai needs to do better.

Hyundai motor America (hma) denied my engine replacement claim (PA# [xxx]) under their extended warranty program, specifically campaign txxi. This claim involves my 2016 Hyundai Sonata se 2. 4 , VIN # [xxx] , which exhibits all the symptoms and engine damage outlined in the campaign, yet my request for a free engine replacement has been unjustly denied. Campaign txxi, as explained in the technical service bulletin issued by Hyundai, extends the engine warranty applicable to 2015-2019 model year Sonata (lf) vehicles equipped with theta ii 2. 0l turbo and 2. 4l gdi engines. This warranty covers engine long block repair or replacement due to engine damage or malfunction from connecting rod bearing wear and extends to a limited lifetime warranty, valid for both original and subsequent owners. O on or about [xxx], my vehicle exhibited a blinking check engine light on the dash, entered into limp mode, and a knocking noise was coming from the engine. O as I was driving the vehicle to the Hyundai of north miami service center on [xxx] (21400 NW 2nd av. , miami, FL 33169) for inspection, the engine locked up and stop, necessitating a call to a towing truck company to complete the trip. O upon inspection, the service center identified significant engine damage, including, engine mechanical failure unable to turn on, and recommended that the vehicle require a new engine replacement. O these findings align with the engine damage described under campaign txxi. O despite meeting the campaign criteria, hma denied my claim (PA#xxx) for an engine replacement on 11/22/2024. O hma based its denial to my claim on the review of engine pictures and my inability to provide evidence supporting oil maintenance intervals between 35k- 68k miles, 78k-99k miles, and 142k-163k miles. Hma cited these maintenance gaps as the basis for suspecting engine neglect, some indications of sludge found on the engine, as the reason for the engine failure and subsequent locking. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C.

Vehicle has been repaired due to broken valve. Vehicle was unsafe to drive. Valve burnt at 70 mph. Car threw misfire code p0303 and started shaking. This issue could have caused an accident. Valves were replaced at young Hyundai in ogden utah. Valves were not covered under the lifetime rod bearing recall. Several people have had this failure on the engjne issue group page. I have a photo of the valve. It is missing a chunk of the valve head. That piece was not located during the valve rebuild. The vehicle had 116,000 miles at time of failure and is consuming 1 quart of oil every 500 miles.

Car has been meticulously maintained with the best oil and premium gasoline. The car is only used on the freeway at 60-70 mph. Husband was on his way home and engine light came on. Car started shaking horribly. He had put a fuel injector cleaner in his recent full tank the day before. Drove car to auto zone. Got the code for misfire on cylinder 3. Replaced all spark plugs. Still code. Replaced cylinder 3 coil. Still code. Swapped cylinder 2 coil with 3. Code still on 3. Took it to shop thinking fuel injectors. Car has no compression on cylinder 3. Needs engine. Hyundai has somehow gotten away with not having to replace engines unless they through a rod. This car has the knock update on it. A lot of others are in the same boat as me. Hyundai should be held accountable for faulty engines. It’s not safe to drive an engine with a bad cylinder that shakes violently.

My engine block or engine has a hole in it. All of my oil came out and my vehicle shut off. My brakes as well is not hard when pressed on, so I would have to pump it till it hardened. My safety and others safety was at risk while I was driving because my vehicle was not coming to a complete stop which could have resulted in a serious or fatal accident. As well as my engine block blowing making all the oil in my vehicle leak all on the road while driving on a busy road. Yes the problem has been confirmed but I was told that my car does not fall under the cars listed with the same issue on the recall list. No it has not been inspected by the manufacturer or police or insurance rep because I am being told I have to pay out of pocket and I am not able to afford the prices being told to me for an issue that I have not caused. There were no warning lamps or anything prior to this incident. I have went to many different mechanics for a diagnostic for my vehicle but they all say my vehicle is fine or they do not know what I am talking about.

Car keep stalling misfire just started muffler sound smoke lack of power when driving.

My car experiences issues around acceleration. It often feels like it gets “stuck” or hesitates when I try to accelerate from a stop (ex. A stoplight) or low speed or when I try to merge onto the highway. At times I have not been able to merge onto the highway at a safe speed because my acceleration gets stuck/lags at a low mph (ex. 35 mph onto a 70 mph highway). My car also excessively consumes oil. I started noticing the excessive oil consumption around 115k miles. My oil lamp does not illuminate when low on oil in nearly all cases I have been low on oil. It has only come on once (did not remain on) and oil was not present on the dipstick. I am 687 miles into my current 1,000-mile oil consumption test and have had to top off my oil twice. I started the test because my oil light flashed and oil was not present on the dipstick. The engine light came on 312 miles into the consumption test. I got a diagnostic code from autozone and relayed the diagnostic code to the dealership. The dealership said the code was related to low oil and to fill up with oil and bring the car to the dealership. I filled it with oil and drove the car to luke’s auto for an independent inspection. Their inspection found that the check engine light was from a failed e-cvvt and additional wear was present. I asked if this could be caused by oil consumption issues and they confirmed the possibility. Just over 300 miles from that incident, I checked my oil and it was once again low. I am deeply concerned about the safety of my vehicle due to it's stalling and indicators of potentially seizing. I have had near collisions on the highway due to my vehicle getting "stuck" while accelerating and unable to enter the highway at a safe speed. I am concerned about the consequences of lack of oil and failure of my oil lamp to illuminate to indicate no oil such as my engine seizing or catching fire. I have reported these concerns to the dealership since 1/2/23 and have reported my concerns to hma.

My car currently has 93000 miles. Since I’ve had 76000 miles, I cannot make it to an oil change without my engine almost running out of oil. My maintenance is always done on time, especially considering I can’t even drive 3000 miles (out of my 5000 mile synthetic oil change life) without my oil light coming on and oil below dipstick. I have taken the car in multiple times, performed multiple engine oil consumption tests and even though my engine is burning a whole quart of oil every 1000 miles, they refuse to replace my engine. I even have an extended warranty through Hyundai so I don’t understand why a defective engine under warranty that literally can’t even drive a whole oil change cycle without running out of oil wouldn’t be replaced by the factory. Please help I’m afraid to take long trips because what if the engine runs out of oil?.

Engine in limp mode, cel activated with code p1326. Knock sensor detection system activated, oil leaking. Car won't rev past 1700 rpm.

My Hyundai is currently experiencing an issue with the engine. At just about 100k miles, the car is having an issue with oil consumption, there are no evident leaks and I am going through 1. 5 quarts of oil in a weeks time (less than 300 miles driven).

While on the highway vehicle started shaking violently, flashing engine light then service hybrid system along with every light on the dash! car still running poorly, stiff steering very hard to slow down to get to safety! by the time I was able to pull over the engine was knocking and a burning smell was coming from the engine compartment. I popped the hood shut the car off , the exhaust manifold and converter(in one together) was so hot it was glowing! I’m thankful I was able to get to safety without it catching fire because it was on its way there! I called for a tow and sent it to the dealer where Hyundai is replacing the engine.

My Sonata has had continuous oil consumption issues. It is now at the dealership for service. They want to do repairs that may not work, to avoid replacing an engine that is under an oil consumption recall. My car had an oil consumption test. At the time the dealership said it passed, this was a couple years ago. It now has the oil issues. The recall extends my warranty to 15 years/150,000 miles. If I have the repairs and they fail, the engine could seize up while I am driving it.

Thus is the second time my motor has blew up due to a recall in a year Hyundai refuses to replace my engine due to my driver door bring damaged. My vehicle is still being paid on and is fully covered. I was told to get it towed somewhere else and I'm about to lose my job due to nor having transportation.

We were told from tulsa Hyundai that our car was involved in a massive recall due to engine failure and that the warranty had been extended to 150,000 miles on theta engines. They told us we had to follow the process in order to have a claim submitted to Hyundai corporate. They required us to pay for a valve gasket replacement and a valve cover gasket ($1000), then to take the car home and drive for 1000 miles and then bring it back in. We brought it back in and were required to pay for a combustion cleaning (around $800) and then take it home and drive it for 1000 miles. We brought it back in and they performed the oil consumption test. They then submitted the claim to Hyundai and we heard back the next day (9/18/2024) that they were denying they claim due to it being an issue with piston rings instead of rod bearing failure. I called Hyundai and they basically said there was nothing else they would do. They told us we could be reimbursed for the $1800 we had to spend to go through that process. Those fees were incurred were not necessary, especially when Hyundai is not going to replace the engine. Hyundai markets on their dealer websites, "engines for life", yet they will do nothing to replace our engine that is in failure.

This car looses oil continuously. I put a quart of oil in it every week. Due to this oil leaking into the engine I have had many costly repairs to replace spark plugs, coil packs, air sensor and throttle. In the winter the coolant needs replaced weekly and no idea where that is being used at. Now again the car must go back to dealership for repairs for rough idle and loosing power while driving.

The contact owns a 2016 Hyundai Sonata. The contact stated that the vehicle was experiencing excessive oil consumption. The contact stated that 30 quarts of oil had been added to the vehicle in the past four months. The contact stated while driving 65 mph on the freeway, the vehicle started shuddering. The check engine warning light was illuminated. The contact was able to exit the freeway; however, the vehicle stalled. The low oil pressure warning light was illuminated. The contact was able to pull into the nearest parking lot, and the contact turned off the vehicle. The vehicle had not been taken to the dealer. The vehicle was not diagnosed or repaired. The contact related the failure to undisclosed recalls. The manufacturer was made aware of the failure and confirmed that there were no recalls associated with the VIN. The manufacturer advised the contact to have an oil change performed on the vehicle. The failure mileage was 132,000.

Vehicle suddenly shuts down while driving. This has happened several times and has cost lengthy repairs and towing fees but still keeps doing the same thing. After it shuts down once the car is reset it will work again for a little while and do the same thing over again.

Taking more engine oil and knocking engine noise.

Car is still driving good, but after I've had it for a little over a year now the first thing I noticed was my horn went out, then the headlights went out, then my temp gage is flashing and the engine light comes on & off. Certain dash lights come on & off. I just got an oil change. I've been taking my vehicles to pep boys for several years now. My last oil change on the sanoto was the 3rd or 4th oil change . One of the reps told me that my car is now consuming oil. He said it's not leaking on the ground but something is causing the oil to burn. I don't know if you have a warranty on it but he suggested I take it to the dealership. Again I've only had it a little over a year. I'm financing the vehicle and have about 4 more years to go. Help!.

The contact owns a 2016 Hyundai Sonata. The contact stated that while driving at approximately 65 mph, the vehicle unexpectedly lost motive power. The check engine warning light illuminated. The contact was able to pull the vehicle to the side of the road. The vehicle was able to be restarted, and the contact noticed an abnormal sound emanating from the engine compartment. The vehicle was taken to an independent mechanic who determined that the engine needed to be replaced. The contact was advised by the independent mechanic that the failure with his vehicle is a common manufacturer failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 111,000.

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.

The oil box does not look right, also there is an orange handle dipstick to check the oil. The dipstick should be yellow.

The motor burns oil causing oil to turn black. I have to add oil weekly and get oil changed every month regardless of mileage. The mechanic that works on it said that dipstick is wrong color and doesn’t look right in engine.

While driving (speed doesn’t matter, highway or city streets) the check hybrid system turn off engine message/code comes on. When u turn off the car and wait for a period of time the it’s not there anymore but the check engine light stays on and the car drive normal until the code comes back up. When the message comes up the engine loses power and and the car just slows down until the car is turned off. This is a safety hazard when you’re driving on a freeway and especially a freeway with no shoulder to pull over on or going through a read light with no speed. The car just does it periodically and when u take it to the dealership they say they can’t duplicate the problem. When all u do is hook a computer up and look for a code when the problem arises while driving you’re never going to find the issue. No the dealer hasn’t reproduced the problem because they didn’t drive the car just leaving it to sit up and checking codes doesn’t bring the problem to light. They wasn’t any warning signal or codes before this but not code p2600 and code p0401 are coming up. Spending $2000 for a part that will can’t be ordered anywhere but from the dealership and the problem still exist is not being logical. So many online reviews have the same problem and not one person has found out the problem from changing the electric water pump to transmission to the engine the warning sign still come back after some time. Me not being the 1st owner and the car out of warranty due to mileage is just robbing folks blinds with no solution.

I was driving on the highway yesterday at 85mph when the engine light started flashing and the rpms went haywire. Then within 2 minutes of this taking place the car began to slow down and not want to go any further. I managed to get over to the shoulder of the road when the engine just shut off and would not restart. The engine drinks oil like crazy. We put oil in it every week and get frequent oil changes. On the day that it broke down on, I had been to the oil lube center that we do business with and had them top off all of my fluids. After looking into this problem online, it appears that there are many other people suffering with the same lemon of a car. Hyundai knows that there is a real problem with the 2016 Sonata, and they are not doing anything about it. We have spoken to the dealerships, and they say there's nothing they can do about the problem because it is out of warranty. We're still making payments on this vehicle and can't even drive it now. The mechanics said that the vehicle needs a new engine. Hyundai needs to issue a recall and help their customers instead of turning a blind eye to the problem. Driving at high speeds with absolutely no indication that there is a problem is a real danger. No indication lights had come on other that the flashing engine light and then within two minutes, dead on the side of the road.

Hello, my name is blake turner, hopefully this peaks your interest. I have been thru and thru with Hyundai about this oil consumption and to be honest I have had it with this terrible company. Unwilling to take responsibility for faulty engine issues in millions of individuals with the Hyundai brand. Seems to me like this brand is all for profit and not for the customers. I should not have to pay for a combustion cleaning, multiple oil consumption test that are destroying my engine further in hopes that they will replace my engine out of “goodwill” with no guarantee. This issue should definitely be added to the other recall vehicles that are listed for oil consumption problems, yet isn’t. There’s no reason my car should be burning through 5 quarts of oil in less than a week, this is obviously a manufacture issue and to be told the problem was a cracked oil pan that I paid $700 to fix at the dealership just to find out, that was not the issue, my car was not diagnosed correctly and I was charged for this oil pan replacement for absolutely no reason being that my vehicle is still consuming oil, not leaking oil. I have checked for oil leaks myself, that is not the issue. My engine is consuming oil at a very rapid rate in the event I drive my car more than the 15 miles I drive to work and back, one errand run and 5 days of driving back and forth to work should not be using that much oil. My engine is getting hot from a 15 mile drive to work and I should not have to damage my engine further if Hyundai can not even promise me a replacement in the event my engine burns up. No kind of loaner car available. This is just a terrible company all around and I’m ready to just switch to a different vehicle brand as this company obviously does not take responsibility for the issues that millions of individuals are having at this very moment. I spoke to a case manager and she tells me I will receive an engine replacement if my oil combustion cleaning fails, when I asked for that in.

1st incident: the engine lost its acceleration power on the highway, giving a rattling noise. It was identified as misfire in cylinder 3. This was repaired and gaskets and timing chain replaced. 2nd incident: the engine lost acceleration again on the highway with a loud rattling noise. On checking the obd scanner it showed the knock sensor as the problem. On taking it into the dealership a ksds software update was done. Current situation: the car drinks up 2-3 qt of oil for every 1000 miles and has an intermittent rattling noise when accelerating losing engine acceleration power on the middle of the highway is a very serious issue. And this keeps happening multiple times and Hyundai has refused to give me a proper explanation on this issue. Other mechanics have suggested to get a replacement from Hyundai as there is already a lawsuit against these faulty engines. On contacting Hyundai there has been no proper response. Please look into this as losing power on a busy highway poses danger not only to our car but to other oncoming vehicles as well. It has been a very harrowing experience for us and I am left with no option but to drive a faulty car which might lose power at anytime.

The 2016 Hyundai Sonata 2. 4l engine have an abnormal oil consumption, every 1,000 miles consume 1 quart of oil. After the discover of the issue, the car was took to Hyundai dealership for service and confirmed the car have an excessive oil consumption. They performed engine flush with additives to clean up the engine and see if the oil consumption diminished. An oil consumption test is currently in process to see if there are positive results. I read multiple articles about oil consumption issues and most of the cases Hyundai decide to replace the engine.
