2017 HYUNDAI SONATA Engine Problems

The contact owns a 2017 Hyundai Sonata. The contact stated while driving 65 MPH, the vehicle stalled without warning. The vehicle was towed to an independent mechanic and the dealer; however, the cause of the failure was not determined. The contact was informed by the dealer that there was an unstated recall on the vehicle; however, the recall campaign had expired. The manufacturer was not notified of the failure. The vehicle remained in the possession of the dealer and was not yet repaired. The failure mileage was 107,084.

Without warning my car started consuming oil while still under manufacturer warranty. Hyundai had me do 2 oil consumption tests and they did there so called engine cleaning which they said should fix the problem on 2 different occasions and not even 3 months apart, well the engine was still consuming oil and now the oil is messing up my spark plugs and Hyundai refused to fix it. There is enough evidence out there that shows Hyundai knows their piston rings in the engines were no good for years and still keeps selling these engines without warning the customer. Hyundai refused to honor their warranty on the engine cleaning solution that the dealership is required to use by Hyundai itself. My car's engine went in less than 7 months after they first started doing the oil consumption test on my car and now refuse to fix or replace the engine....

The motor in this vehicle consumes oil like a drunken sailor consumes alcohol. I have the oil changed, and before the next scheduled oil change, the car had The oil indicator light come on. I immediately went to the nearest AutoZone and purchased oil and put in the car. I took it to the dealership and they told me they were aware of the issue surrounding the motor in this make and model of vehicle however, my Vin number was not included on the recall. So they could do nothing to help me. This is a safety issue because the motor should go at least 3000 miles with without having to have, a full 5 quarts of oil put back in because it’s sitting on empty. I have been dealing with this for over a year with the local dealership and with Hyundai USA to no avail

The engine light keeps going on and off and I reported to their dealer a couple times during the warranty but when they checked the car the light got off and they asked me to keep driving it until out of warranty and they ask me to pay for fix the same problem

Engine oil is consumption. I went to dealer they send the the request to the Hyundai that my engine oil is consuming. The Hyundai reject to replace the new engine for the following resons. 1. I am not the original owner 2. the car has 129k miles

Have problem with high oil consumption which caused carbon deposits to burn valves. I was driving on the highway when engine light came on the car lost power and stalled on the road. At highway speeds that could have caused a collision with traffic. The car was bought at a dealer with 35000 miles on it when I started to notice a slight problem. The car now has 88500 miles on it and has gotten worse. The dealer said it needs a new engine which Hyundai has denied. The dealer said too many mile’s between oil changes but all maintenance has been done when needed at the dealer and Big-O. I have noticed online many complaints with the same problem. I contacted Hyundai have case #23502874 Cost to repair $9743.94 at dealer

While driving on the highway the car stopped .. it was towed to Hyundai as it is still under warranty and ultimately we were told it suffered "catastrophic engine failure" I was also told that a new engine would not be covered. When I asked why I was instructed to give maintenance records which I did. It was denied BEFORE they asked for records. I have been going back and forth with Hyundai and the reason they have given me is an exact effect of their ongoing issues with the THETA II- GDI engine. I have compiled so much research regarding the defect and Hyundai stopped responding to me when I asked them the difference between my car's engine and those that Hyundai knowing delayed recalling and the thousands of same engines that have determined as defective. This has been going on for months and I am not going to...

I was driving down the freeway when my engine made a loud knocking noise, the noise got worse as the RPMs increased. The check engine light began to flash and I lost power, the vehicle will not exceed 60mph and vibrates when moving down the road. I believe this issue is widely know about and should be addressed and forced into a recall. I have maintained the vehicle and should not be responsible for a manufacturing error.

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.

My car was eating up oil and there was no leak in it. Then the vehicle stopped working. I kept up the maintenance for the vehicle and when I reached out to Hyundai they told me to take it to my local dealership to get fixed and they stated that they could not fix it, but according to the class action suite I was suppose to get it fixed

WHEN I DRIVING MY CAR DROPPED 20 MPH DURING ENGINE RUNNING. HYUNDAI CAR CARE CENTER REPAIRED WITH $4825.35. AFTER 10 DAYS AFTER I PICKED MY CAR, I HAD SAME PROBLEM. I ALSO PAID $1864.67 TO TAKE CARE OF CAR PROBLEM. I THINK THIS PROBLEM HAS TO TAKE CARE OF RECALL. I REQUESTED HYUNDAI RECALL CAMPAIGN CENTER BUT NO ANSWER. I NEED YOUR HELP.

My car has been burning excessive amounts of oil for the past 6 months now. It is so bad there is excessive carbin built up in the piston rings that caused my engine to missfire 2 times in less than six months. Today 5-7-2024 to my car back to the dealer for that problem and they told me I need a new engine but unfortunately it was not coverd by the engine extended warranty. Please help me resolve this issue because I cannot afford a new engine or a car.

The engine was the part which failed. While driving the engine stalled and would not go forward. A foul smell was coming from the engine and the engine was rattling. The floor was wet on the passenger side interior. We let it cool down and took it to the dealer. They did not offer any explanation concerning why the car was not operating poorly or why the car smelled bad or why it stalled frequently and lost full power. Steve Taylor Hyundai service department quote "we don't know what's wrong with your car". It had 78383 miles on it. Taylor Hyundai said we can trade it in but you will have negative equity on your new loan. We were not credited for our trade in but we lost 4 or 5 thousand dollars on the trade-in. They did not cover the car with the warranty and did not repair it....

While driving on a highway at ~60 mph, the check engine light came on (plus other indicator lights) and the car immediately dropped to ~45 mph. ~20 seconds later, while trying to pull into a school parking lot, the hybrid system fault warning came on and the car dropped to ~5-10 mph and then became extremely difficult to control. The car was towed ~80 miles to my home dealership and it was diagnosed as a partially blocked EGR tube. ~1 month later, on the next longer drive I had to make (all other drives were short distances), ~70 miles into the drive, the car started making a knocking sound and then suffered the same failure under the same kind of conditions. This was diagnosed as a failed knock sensor. One week later I tried to drive it a long distance to see if the problem would happen again (but closer...

The car started to stall and engine lights were flashing in the middle of interstate and it wouldn’t go above 60mph almost was about to get hit from the back

A couple of weeks ago my car seemed to be skipping when I started driving. I had no idea what could be wrong but some kind of intuition made me think to check the oil. I had the oil changed in December 2023 but had only driven about 1000 miles since then. I'm working from home so not driving alot. My oil was VERY low - it didn't even measure up to the first fill line. I started reading info online and realized that many Hyundai Sonata owners were reporting similar issues, so I went to an auto store bought a quart of oil and put that in. After testing, I got another quart of oil and put that in, finally bringing oil level to amount recommended by the lines on the oil stick. A couple days later I took my car to the local dealer, Tuscaloosa Hyundai. As soon...

My son was driving the car, and completely out of nowhere it seized to have any compression and steering/accelerating became disabled. I have been given an estimate up to $7,000 for an engine rebuild due to this happening. I have reached out to Hyundai and they denied my claim due to car being out of warranty. This should have never happened when the car has been well maintained,even with the motor burning through oil faster than it should be, which I have always kept a close eye on. This car is defective and unsafe.

My husband was driving the car on I95 yesterday, no lights on on the dashboard. Suddenly, the engine stalled and he had to pull out before it completely stopped. He could not get the car to start again. The only light on at that moment was a light indicating the key was not inside the car. He went home with a friend to get the other key, but it didn't started as well. The car spent the night at a shoulder on I95. This morning, he called an independent service center and after checking the car, they said the engine stalled because it run out of oil. There was no apparent leak and no lights indicating a problem with the engine oil. It was changed 2,000 miles ago only. The mechanic also mentioned that Hyundai had similar problems with other cars and that we should call them for that. Since...

I have observed that my Hyundai sonata 2017 randomly lose power while driving. Also, sometimes the car vibrates when I am driving. I went to the mechanics few times for them to check it, and they requested to change the spark plugs as well as the coils, which I did but it continuously do that. I usually go to the Hyundai car dealership for oil change, and they will tell me whatever I need to change in the car, which I always do but still it does that. I believe this is not safe especially when you are driving over 50 miles an hour on a high way, and the car randomly loses power; this can cause a serious accident. I am requesting the intervention of your office in making sure that car company’s uphold to the safety of everyone plying the road.

The passenger seatbelts do not tighten when there is a hard break. My engine is also consuming oil.

5-6 quarts of oil consumption between oil changes. Rattle noise with torque on engine or acceleration.

I have a 2017 Hyundai Sonata sport . I make payments on this vehicle. I have only had this vehicle since [XXX] it just hit 100,000 miles. I was on my way to work and the check engine light came on.. I heard a ticking and knocking sound. Then the car shut off. A few mechanics have looked at the car.. I was told about the defects from shaving not being properly cleaned out.. This has never happened before and this is my only transportation. It’s currently at the Hyundai dealership here in Fredericksburg Virginia. But they of course are telling me it will take up 4 to 6 weeks before even doing an engine inspection on the vehicle and they can’t provide me with a rental. It’s obvious that this is an engine malfunction. I would like to be treated fair in this situation and simply have the engine...

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 purchased my 2017 Hyundai Sonata brand new. At only 37,000 miles, it literally ran out of oil without any prior warning on [XXX], stranding me on the side of the road. The Hyundai dealership has required two oil consumption tests and a combustion chamber cleaning, but the problem continues. This excessive oil consumption issue is well known and well documented by thousands of other Hyundai owners whose vehicles have a Theta II 2.4L engine. Hyundai requires the engine to completely fail before it qualifies for an engine replacement. A friend of mine's Hyundai Sonata caught on fire due to this very same issue while going over the Sunshine Skyway Bridge in St. Petersburg, FL in June 2023. If that isn't a safety issue, I don't know what else is. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2017 Hyundai Sonata is using oil at a ridiculous rate. The rapid oil consumption has caused me to be left stranded twice & I had to have it towed to a mechanic both times. I’m having to take it every 2 weeks to be checked by a mechanic & it’s low everytime I take it to him. He’s had to replace all the spark plugs 2 different times since October of 2023, which is very costly for me. I’m a single, working mother of 4 children. 2 of which are in college. So I definitely can’t afford all the towing & repair fees. I purchased an extended warranty, which covers the engine, when I bought the car. My mechanic has reached out to them to tell them his findings & recommendation. The warranty company thinks it is normal for the car to use a quart of oil every 2...

Check engine light start flickering while I was driving down the road my vehicle went into limp mode and I lost all power. I checked my oil for metallic shavings or a creamy look but everything was cleaned. I got a code 1326 for knock sensor. I replaced and changed the oil and oil filter and reset the code. I started it up and it sounded good then I drove to see if it was fixed got on the highway and my engine went back into limp mode I lost power again. And my engine started flickering I stop the car and tried to turn it back on but my engine locked up. Could I possibly get help with getting a new engine. The car only has 127,052 miles. I heard there was a bunch of problems with rod bearing wear and etc with 2017 Hyundai sonata se

Engine oil light or any warning lights and symbols never came on after Engine had burned out all the oil. Had oil changed and new oil filter installed and in less then a week it burned out 3 quarts, again with no low oil warning at all. Motor stalled at intersection and had to cool down, oil was again added and lower Engine knocking was present. Meanwhile had a mechanic inspect it and diagnostic done and lower bearings are knocking. Vehicle has had this issue for over 4 years and never mentioned to us until now after 100,000 miles. 2019 is when this oil burning issue began. Hyundai dealer serviced this several times and never mentioned the reason for the knocking other then it was low on oil. After breaking down in a busy intersection had to be pushed off road and waited for Engine to cool down to add...

Had cruise control set for 75mph, and while traveling up hill, the car downshifted to maintain speed. After 10-15 seconds I noticed power loss and the check engine began to flash. Disengaged cruise control and pulled off onto the shoulder once I found a safe place to do so. As I was slowing down, there was a very noticeable misfire from the engine and was trying to stall out while still in motion. There was no knocking sound, nor was the car overheating. Once I was fully stopped, the car died and would not start back. Had the car towed back to my house. Replaced spark plugs because cylinders 2 and 4 were not firing properly. Also rotated coil packs around to see if they were failing. Cleared check engine codes but they immediately came back to misfires on cylinders 2 and 4. Did compression tests and found that cylinder...

My 2017 Hyundai Sonata is burning oil. Originally when we realized that our engine was burning oil we were told that we need to get an oil change, which we did. Come back 1000 miles later, we came back and the engine was missing a lot of oil. They topped it off. We came back another 1000 miles later and we again had receding oil levels. They told us they are cleaning the engine. 500 miles later, on Sunday [XXX] our spark plugs blew. We got our car towed to the dealer, Spitzer Hyundai of Cleveland. Spitzer Hyundai is procrastinating and making stories. Each time we do what they ask, they want additional tests done to confirm the engine is burning oil. One of the employees told us at the beginning: we know and you know the engine is burning oil, but Hyundai needs to confirm that. Now the dealership...

My 2017 Hyundai sonata burns oil rapidly, almost 400 miles it burns 5 quarts of oil. The engine stalls randomly and beings to mis fire. The car has stalled on me in the middle of the road with no check engine light or indicator that a problem is present. I have had to change spark plugs and coils far to offen and every time I have to pay the mechanical shop. There is a recall on the hybrids sonatas but not the gas ones. The dealer acknowledges that the car burns oil allot. Which I’ve been told it can lead to engine failure I have done everything possible. And I’ve spoke to other owners and I’m not alone. The vehicle hasn’t been inspected by others such as police. No warning lights appear

I purchased this vehicle with 79k miles less than a year ago and it has barely 90k. My engine light is on, vehicle stalls, and the error codes are revealing misfire involving cylinder #3. I go to the dealership for maintenance, and have kept up with it. Replaced the ignition coil and spark plug for this cylinder and nothing is working. It stalled in the middle of the intersection and I nearly was hit by another vehicle. Supposedly, there are no recalls but I also had issues with the vehicle burning through oil after 1,000 miles of getting oil changed. The dealership claimed nothing was wrong with car but they were so desperate for me to buy this car. Shame on Hyundai.

My daughter wrote you earlier this week about the severe oil oil usage of her 2017 Hyundai Sonata. I am writing a follow up because I co-signed for her vehicle when she and her children were deserted by her husband. Since my name is listed first on her vehicle title and bank loan I have a special interest in the problems she is experiencing with her Sonata. She indicated in her filing with your department that she has had her local Hyundai dealership change her oil every four to five thousand miles which is true. The last time the oil was changed by the dealership was around [XXX]. When she spoke to the service department last week she was informed that since the VIN was not listed as being part of a recall there was nothing they could do for her. Yet this past week I put four additional quarts...

While driving on the highway the car began shaking, the check engine light came on. After guiding the car to the shoulder, we turned the car off and back on after a few minutes. The engine was completely stalled when we turned the car back on - multiple dash lights were on (check engine, oil, and battery were the ones I remember); the car would not accelerate, when we attempted to drive slowly the car, in drive, started rolling backwards/downhill and would not accelerate at all; and the engine was still idling shakily. Car was towed to a mechanic who diagnosed an engine misfire requiring engine replacement. Hyundai dealership denied this as a warrantable issue under Extended Warranty TXXI/TXXC/Service Campaign T3G. This vehicle is a well-kept 2017 with only 90k miles and should not have had this type of engine failure except as a result of poor manufacture.

Engine has been burning oil I kept taking it to Hyundai to get it repaired and do the trial test to get it fixed they refused to repair. Engine has now blown I would like my car repaired I want to keep it. If possible

Twice in the past two months the vehicle enters a rough low RPM. Will not respond to the accelerator and the engine shuts down. First was in a parking lot the second while driving in school zone traffic. Was able to safely get off the road the second time. The parking lot I waited a few minutes and the engine ran normally. Same for the second time, waited a few minutes and it would not start then a few more minutes it started and ran. Both times all dash warning light lit up but just for a few seconds. If this happens at highway speeds a good outcome seems risky.

Last week as I was driving the engine oil warning light came on. I pulled into a parking lot immediately and turned off my Sonata. After a few minutes I checked the oil and found no oil on the dip stick. I added oil and returned home where I checked online and discovered that there was a recall for Hyundai Sonatas using or burning excessive amounts of oil and ruining the engine. I called my local dealership and was told that my VIN is not included in the recall. It cost thousands of dollars to repair or replace an engine. How could my VIN not be included? The dealership offered no help. I go to the local dealership to have my oil changed every four to five thousand miles.

THE ENGINE WOULD BURN UP OIL NOW CYCLINDER 4 IS NO LONGER PROPERLY WORKING AND I NEED A NEW ENGINE. STARTED IN AUGUST 2023, NEEDED SPARK PLUGS AND FUEL LINE REPAIR.

Drove vehicle to Arkansas one way checked the oil it had burned out replace with a full 5 quart

has went less than a 1000 miles car had full oil change on 9/17/23 had to add 4 qts of oil

During travel on highway (~60 MPH), the vehicle suddenly lost power and the engine stopped functioning properly. The effect of the problem was that the vehicle began to 'buck' - as if the engine was having significant trouble running continuously. The engine light then illuminated solidly (not blinking). The vehicle slowed from lack of power and I was forced to move to the right lane/break-down lane through high speed highway traffic (NJ). I was able to travel /limp a few miles slowly to the next exit and get off the highway to a gas station. The engine ceased operation upon arrival to the gas station. The vehicle was towed to a mechanic who diagnosed the issue as engine failure. The vehicle was towed to a Hyundai dealership for diagnosis by the manufacturer (Denville, NJ). The diagnosis was 'engine failure'. No conditions existed prior to this event. In the recent past,...

engine burned up oil just had oil change 9/17/23 had to add oil to add 5QT of oil to engine

had to put in 5qts of oil due to engine is burning the oil just had oil change 9/17/23

Engine went through 5 qts of oil and had to refill on 8/31/23 had the oil changed by Hiley Hyundai on 6/17/23 they entered the wrong mileage during the engine consumption test

had the oil consumption test done it failed and has been putting oil into the engine every 1000 miles or less due to engine burring up the oil had Hiley Hyundai due and oil change on 6/17/23 had to add 5qt of oil to engine on this day

Engine went in for the second oil consumption test on 6/17/23 where Hiley Hyundai did not record the correct mileage they put that mileage at that time was 123,893 when it should have read 126161 ( which was 4k miles more than the time of this report) than that therefore it lead Hyundai to believe that the engine was not burning oil and we was in the write mileage due to human error we was denied a new engine and because this is the only car that we have at this time and Hiley has no loaners and we are in CH 13 Bankruptcy we do not have the funds to rent car out

I'm reporting the growing concern of my engine having rod knock or seizing . It has been burning excessive oil since I bought it at 80k miles. I have reached out to hyundai and they have denied me any help as the vehicle is past their 10y/100k mile warranty. Although my vehicle has extended warranty up to 150k miles for engine seize or rod bearing failure through them. There's no warning lamp but the piston slap noise is getting louder, I'm scared this problem might leave my family and I stranded in the middle of the night. Also scared that it can catch on fire due to almost running with no oil. I have to do my oil change every 1200 miles, instead of 3000. corporate hyundai has denied any type of assistance, I went to a dealer to get it checked out and they insist without proof of oil...

I was stopped at a red light. Once light turned green I went to make a left-hand turn. My vehicles power steering shorted out, almost causing me to hit a pedestrian and child.

I was taking the car doing the oil consumption test for the 3rd time and I had just got it out the shop one hour before this happen
