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.

I have a 2017 Hyundai Sonata sport. I make payments on this vehicle. I have only had this vehicle since 2/19/21 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 replaced along with any other vehicle updates or at least another vehicle.

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.

- Albany, NY, USA

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 weeks. I need help asap as my warranty will expire in 8,000 more miles. Please help me resolve this issue so I-??m not left stranded again.

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)

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

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 oil and knocking continued.

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 2 had 0psi and cylinder 4 had 20psi. Car was not low on oil and no other warning lamps were on.

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 is asking us to drive another 1000 miles again. The problem is that the spark plugs are shot and need to be replaced. They only need to be replaced because of the faulty engine. They want us to pay $700 to replace the spark plugs when it might fail again in another 100 miles. Meanwhile we have car rental expenses plus other expenses and a headache dealing with the company Hyundai and the dealership Spitzer Hyundai. every time I drove those 1000 miles i was always worried that the engine would stop working if the oil would burn out. My local mechanic is the one who diagnosed my engine to burn oil, and he said not to replace the spark plugs, because it will fail once again. Even if they approve the engine replacement they will probably want to charge us $700 for the cost to "take apart the engine and send pictures to Hyundai". The engine light has been constantly going on about every 1000 miles or so. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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 of oil in the engine. She and her children live with her mother and me. I can attest to the fact that there is no smoke from the exhaust when the vehicle is idling which would indicate bad valve guides. Nor is there smoke from the exhaust when the car is being driven on the road which would be caused by bad oil rings on the pistons. There is no oil being dripped on our driveway or garage floor which would indicate gasket or seals leaking, but the car is consuming oil at an alarming rate and we need your assistance with this issue. Thank you for your time. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

- Poinciana, FL, USA

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.

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 changes there's nothing they can do, i do them myself on all my cars and I'm VERY on top of my maintenance. I have scheduled an appointment 02/07/2024 to try and diagnose the growing issues with the engine itself.
