Motor issue. Took vehicle in for routine service. Hyundai Sonata Limited Hybrid year 2017. Purchased and took possession of vehicle in May 2018. Purchase New. Current miles 41,000. When doing routine service, tech discovered that head gaskets were now damp and indicating coolant fluid leak. 1) Failed component - head gaskets. 2) Safety risk - none at this time. Car is functional and operating normally at this time. 3) Dealer discovered issue. 4) Vehicle has not been inspected by someone other than dealer. Exclusive dealer service since purchased. 5) No warning lights or any other such indication of failure. No leaking or wet spots under vehicle when parked. Dealer at this time ordering parts and to schedule service repair. Have called Hyundai and filed a claim on this matter. Concern is that there is a prior recall for the motor regarding internal bearing failure. At that time, vehicle was inspected for this recall and was determined that there is no defect/problem existing or in progress. I am desiring that Hyundai replace the entire motor and not just repair due to the known other mechanical recall. As of this time, there is no determination made on my request.

The Abs brakes and traction control go in and out and affects the brakes while driving, I know there been reports of fire but for some reason my car is not in the recall, same thing with the air bags lights come on showing faulty air bags and on scanner tools but not recalled even though Hyundai knows about these issues. Now for engine I went to have my engine looked at 2 times for oil consumption and all they did was a combustion chamber cleaning twice which both failed in less the 8100 miles so when I took it back for another oil consumption test for the 3rd time today, the engine light came on, it started knocking, lost power and riding rough. Well, they did an engine scanner test and suspect faulty rings allowing oil into the combustion chamber and fouling my new sparks plugs that was installed less then 10000 miles ago, now they tell me I need a new engine and refuse to replace it for free even though they said they fixed the problem before with the engine cleaning now the same part is the problem and now, I am without a car to drive! They tell me I can lose power while driving which could lead to a car accident.

On or about August 13 2022, I notice the oil engine light come for a second, then it went off. After parking vehicle at my home and letting the engine cool off a bit and oil to settle, I checked dipstick only to find out that is was showing DRY no oils whatsoever, I then bought 1 qt of oil and added it to engine still dip stick showed dry and not a drop of oil on it. With still 3,000 miles to go before my next oil change, I decided to take it to PepBoys for a new oil change. After one week dip stick was showing oil on the low side and this time the metal on the stick showed whiteish, like it had been over heated. after this decided to take it to dealership GOSH HYUNDAI In Hemet 92545. I was told it would take 2 days to do some checks and get it ready for an oil consumption test. That is drive vehicle 1000 miles then take it in for another inspection (hopefully 1 day) then getting it back, drive another 1000 miles, then take back for another inspection. Being this my only Vehicle at this time, I am not sure why it takes so long to figure this out. OH did I mention Hyundai headquarters (I'm guessing) has to approve the oil consumption test, otherwise I am out a vehicle and have to pay for repairs. Not too mention the brake fluid reservoir is doing the exact same thing, fluid is being completely replaced every month to month and a half, by replace I mean adding a full reservoir worth of fluid because it seems to be evaporating. I am on the the third time adding fluid to this vehicle after GOSH Hyundai worked on my brakes (10000 miles a go). But this one I will have to pay 165 dollars for them to check it out. Nothing was said about me paying for engine oil issue check, plus they had me sign a affidavit to make sure I was the only owner on vehicle witch I am...So now the waiting game begins and to wait until someone makes a decision about fixing this issues?!!

It-??s has taken 15,279 miles, 8 months, 8 oil consumption tests, a sh*tty service provider, service provider minions doing his job, worried everyday driving around my car that the engine would fail, set on fire or the engine would sputter and die on the freeway; to today being told they would have my vehicle 4-6 hours to do a complete engine walk through. Thank god I hadn-??t left the lot 45 minutes after dropping off my vehicle getting called and told they will need my vehicle for 12 hours!!! I asked to see the higher up manager today; (who didn-??t haven time to show his face) but could clearly get me a brand new 2022 Hyundai Tucson with 4600 miles on it for rental. Hyundai do better! I-??ve played the game, now it-??s time to fix my vehicle that is your duty under the 100k miles power train warranty. I have personally noted each event since March 2nd when I realized this was going south

The oil light would blink on, then go back offstarting abiut 7/15/22. We checked the oil, but it was fine. This happened for about 2wks, w/ the light never staying on or staying on & flashing. However, the oil consumption started increasing, needing more oil each time, but no indication of a leak. Then the check engine light started flashing & car went into limp mode w/engine knocking. This happened suddenly in traffic, which could have caused a wreck d/t sudden loss of power & inability to reach speed of surrounding vehicles. At this time, the oil light was not present, but 3qt of oil needed to be added in order to limp the car home. This was 7/39/22. Computer check gave code 1326. Engine failure seems immenent. Vehicle is available for inspection request. The issue has not been confirmed by dealer, but we have seen similar complaints on YouTube.

IT is burning oil and am very afraid to drive this car before it catches on fire....I am hoping the dealer will replace the engine or Hyundai Motor company to give us warranty without the hassle...

It's knock sensor issue code was showing since 85000 mileage, dealer just got rid of the code and said can drive safely. Then again at 101000 mileage knock sensor code and Hyundai dealer said software is updated can drive safely. Also it's engine oil burning faster that we keep on topup oil all time. Then at after 108000 mileage my car started overheating, & it's engine seized. Now Hyundai don't want to fix such problems. I don't know maybe it get fixed, then catches fire on highway can cause death.

2017 Hyundai Sonata Sport engine is consuming oil at 85,000 miles and has done so since early 2022. I have had the vehicle to the dealer on numerous occasions regarding this issue; oil light coming on and immediately needing 3 quarts or more to fill it back up. The latest encounter was 7/17/2022 when the check engine light came on and when oil was checked, it was on the "L" level yet again and this was less than 800 miles since the complete oil change where 5 quarts of oil was inserted. This engine is known for oil consumption and at 85,000 miles it should not be doing it at this rate. Another consumption test is being requested.

I'm now having to check my oil on a car I still have a loan on once a week and having to add at least 3 qts everyother dealership wants 600 for a diagnostic run to see if there's a defect

- Elyria, OH, USA

Engine has 131,000 is driven less than 800 miles per month currently. And has excessive oil consumption. An averageof 2-1/2 to 3 qts of oil in a month. I first notice this problem, when I checked oil level about 3 months ago. Oil warning light never comes on letting you know it is low on oil.I contacted huyndai dealership and was told I need to pay for 6 oil changes. And an engine clean up to determine what problem is. It is clearly a factory defect that they are not willing to admit to. Customer should not be liable for a factory defect. Ive read Hyundai forums and founf many owners with same complaint but no action has been taken. Need help with this..

After travelling on the highway for approximately 1 hour the HEV light along with several other lights came on and the engine powered down. The instructions were to turn off the engine immediately. Luckily I was in the right lane and was able to get to the shoulder of the highway and turn off the engine. Tried several times to restart, but same message came up to turn off engine. Had it towed to closest Hyundai dealer for service. They couldn't look at it immediately, but according to them it started the next day and they drove it around (local driving) for 10 miles with no issues. I took the car back and after driving it again on the highway for 1 hour the same problem occurred and I had to have towed to my local Hyundai dealer. It has been in their shop for over 3 weeks and I still have no answers as to what may have caused the problem.
