Sonata Sport 2.4L

  • Automatic transmission
  • 156,084 miles


I know engine problems are not rare but when we got the Sonata for our daughter as her first car we were hopeful it would be a good starter car for a teenager and get her through high school. We bought it 4 years ago with 90K miles on it and It had 150K miles on it when we gave it to her and 6 months later we now have a really big paper weight in the driveway and disappointed daughter. It's eating about a quart of oil every 500-800 miles and making a ticking/knocking sound. check engine light on with the knock sensor error code P0326. Likely needs a new engine our mechanic said and Hyundai said "too bad so sad" when we contacted a local dealer. I'm not sticking 6-8K into a car with 160K miles on it. We're off to buy something else and it won't be a Hyundai or Kia for sure.

Sonata GLS 2.4L

  • Automatic transmission
  • 86,371 miles

I work from home and barely drive my car except driving from Calgary, Alberta to Vancouver, BC or driving to see my partner which is 2 hours driving.

I changed my oil 2 months ago. Only driving I've done was to Vancouver 3 weeks ago from Calgary. I checked my oil today and I have about 1/2" of oil on the dip stick and the oil is black!

I use synthetic 5W-20 and Fram oil filters. I'm not even close to changing my oil at the recommended interval.

I will need to change my oil asap. Very frustrating!!!!!!!

I bought this vehicle because it had only one other owner and it only had approx. 12,000 miles and at the time It seemed like a great idea/ I financed it thru my bank, so I did not have to deal with the dealership, they got their check and everything was OK. There are minor problems with this vehicle and the Hyundai's I have had before, which are very annoying and will be mentioned in other complaints. MY CHECK ENGINE LIGHT WENT ON/ so I go to my mechanic, I always get my oil done. He tells me he has seen this before in this company it is the oil seal ( I Believe) that is gone(inferior product) and the oil is going into the spark plugs. So He tells me that replacing the engine is really this only way to get this fixed! My mechanic kept fixing the problem by cleaning the spark plugs a lot and after each oil change.

The car seemed to work but I had to keep checking the oil levels so the oil would not run out/and with all the other problems with it/it just became very frustrating. I was still paying on this vehicle to the bank!!! Sometimes the mechanic did not charge me to clean the spark plugs and get rid of the CHECK ENGINE LIGHT/ I finally Owned the vehicle after a year of sending letters to the Hyundai Corporation/the Better Business Bureau/ the Attorney Generals offices in Mass and New Hampshire to NO AVAIL!!!!!

I purchased the vehicle in MASS But I Live in NEW Hampshire/ The dealership in New Hampshire charges to do A diagnosis. And I felt I had done enough for A vehicle I did not create or get $$$ for and it was up to them to diagnosis it for free The HYUNDAI CORPORATION said they would need me to pay to get the info they needed even though I sent them the Mechanics letter and even a letter with some info from the dealership during a recall...Now a year later and no results the vehicle will not pass inspection the engine light will not go out and I now have the title to a 1000 pound paper weight that I call my eight year old car. I really Need HYUNDAI to step up and deal with this there has to be an organization in this world that handles this because I really think complaining is not going to do it!!!!

I have spoken to customer where I work who have similar cars and the complaints are the same. Some have had engine stop like mine and repaired it . Mine has been sitting because I cannot afford to replace it with even a rebuilt engine. Spoken with several mechanics and they all have the same answer about the Sonata and its oil consumption problems. Even the paint on the vehicle is a problem where it is cracking and peeling. I am sure Hyundai has received numerous complaints but is probably stalling to see if they will be able to get away with recalling as it would cost them a tidy sum to deal with replacing engines for many of these vehicles.

Sonata Limited 4 cyl

  • Automatic transmission
  • 97,000 miles

I bought my 2015 Hyundai Sonata in 2018 with 14,500 miles. I drive 60 miles a day to and from work. I now have 101,800 miles on the car. However I noticed the car wasn’t leaking oil but kept running out of oil prior to an oil change. I have my oil changed and tires rotated every 5000 miles. When I had about 96,500 on my car the problem started. I mentioned it to the dealer in Rockville, MD and they said oh your car will be fine we will just wait until after the holidays. I said what’s wrong and they said your car is consuming oil so they must know this is a known issue.

They told me they would have the car for a week but wouldn’t provide a loaner that I could rent a car since I didn’t purchase my car through them. I was so angry. Then someone from the dealership called for me to rate my service. Because I didn’t give them a 10 he badgered me trying to get me to give them a better score. It was terrible. I want my car fixed and I shouldn’t have to pay for it. It’s been a know issue with this model car. I am going to start with the dealership and go right up to corporates. It’s just crazy

Sonata 2.4L

  • Automatic transmission
  • 122,000 miles

My 2015 Hyundai Sonata sits with a blown engine due to the fact that the oil issue that has been looked at several times and no one can figure out why the car burns oil. I purchased this car in 2019 and have issues with everything. What a bad choice. I have a car that won't run due to the oil issue and the fact that never once did the oil light come on to indicate that there was low oil or no oil in the car has left the engine seizing up.

Now to most just fix it right, WRONG, it is a $5000-6000 fix, that I don't have a car that I still owe money on, and Hyundai doesn't care. Shame on them, I also have a 2021 Hyundai Venue that I am getting rid of immediately. Don't want to be in the same boat twice.

Started noticing about 3-4 months ago, and my car was using a lot of oil. It would be extremely low between oil changes. I checked it about 30 days before oil change was due and again very low oil. Not leaking and no smoke coming out of exhaust. Going to get it checked out today but from what I have read this is a common problem. Are there any recalls associated with this car/problem?

Sonata SE 2.4L

  • Automatic transmission
  • 237,000 miles

First engine was replace by Hyundai after test showed car used 1 quart every 800 miles. Second engine started to use oil excessively at about 70K miles on replacement. No satisfaction with Hyundai service. I went back for consumption test in April 22. I did 3 tests to find out they lost original oil change paperwork that was done at dealership and then said Hyundai denied claim.

After contacting Hyundai customer support told to go back to dealership for test. I went back to dealership to be told they need to keep car for a week to do engine combustion test. No rental or car provided. I have no other car and I must be able to drive to work. This is unacceptable. I have spent so much money for extra oil and premium gas on first engine. I have maintained my car as it is my only transportation and I need help with this.

Meanwhile, here I am driving around with quarts of oil in my car. No engine light ever came on to alert me, but I could hear the difference in the engine sounds that told me there was a problem. Now I have to add oil more often than I did with the replaced engine.

Update from Sep 13, 2022: I am time stamping pictures and documenting all of the oil I am adding, saving receipts and taking pictures of mileage as the time I add the oil.

Sonata SE 2.4L

  • Automatic transmission

I bought this car used with 90k on it. I became aware of the global/widespread Hyundai issue with engine oil consumption and began checking the oil frequently and realized that it was consuming oil. I had talked to the local dealer about another Hyundai I own and they conveyed that if the engine wasn't knocking Hyundai wouldn't replace, or otherwise, attempt to fix the engine. Basically, I'm waiting for the engine to break and then move on with my life.

Sonata Sport V4 Gdi

  • Automatic transmission
  • 80,000 miles

This is crazy - the car just felt very heavy, so I checked the oil and to my surprise there is less than a quart left. Started investigating, and I found that the GDI engine on this car burns oils like crazy. No warning lights or anything. Took it to the dealer and we are in the process of investigating. A friend of mine got an engine replacement. But, I don't think that is going to solve the issue.

Sonata in burning oil with no oil leaks being left on driveway. I know get it checked every week as the shop I use for oil changes will fill up for free, but they warned me even with them checking between full changes my oil level did not even read on the dip stick last oil change. They had just added 2.5 quarts of oil 1500 miles ago. Tech told me I'm driving a ticking time bomb before this engine becomes seized.

excessive oil consumption excessive oil consumption

1/2022. My vehicle start leaking oil. Vehicle was under warranty. Had multiple things replaced. I thought oil leak was fixed. Not even a month later in 2/2022, the vehicle was leaking oil again. Brought it back to dealer & they redid gaskets, seals, etc.

Now on 4/22/22, I have not even put 3000 miles on the vehicle since it was at the dealership & there was a knocking noise coming from under my hood. Called the dealership and they said I needed to get it back to them. Oil consumption test was never done because it was assumed that my oil was low because it was leaking. Both times oil was put in my vehicle.

On 4/28/22, I was at work and went outside to check my oil and there was little to no oil on the stick. I immediately added 5 quarts of oil which is required for my vehicle. The knocking did not stop. I left work to run a brief errand on 4/29/22, and had just pulled out of work onto a very busy four-lane highway. All of a sudden I hear this big boom under my hood, my car locks up and my oil light comes on. I immediately took my foot off of the gas and coasted into the next driveway at a business. There was oil all over the road and pouring out from under my car. It happened to be an auto parts store.

A mechanic came outside and looked and said a rod went through my engine block & oil was pouring out of my car. I started to have an anxiety attack and went into shock. Luckily I was not on the interstate because it could have been very bad. I am now without a car. None of the rental car places have any vehicles available and I have a full-time job & am a single mom with 2 kids. The dealership was nice enough to have my car towed to them 45 minutes away. They then told me about an oil consumption problem with Hyundai and there is a big class action lawsuit. This should have never happened. Apparently the oil consumption was never sent out as a recall or anything else so I was unaware of it to even know to check my car other than regular oil changes.

Sonata SE 2.4L

  • Automatic transmission
  • 26,900 miles

Noticed at the first oil change, the mechanic said your oil was low, a little over a half quart. I was not happy to hear that. Kept an eye on it and now have to add about a quarter of quart about ever 1000 miles. I check oil cap was tight and the dipstick to make sure it was properly seated. I have contacted Hyundai about this problem - they did nothing, a wasted call . I bought this at approximately 23,800 miles. I am very upset to pay that price for car with low mileage and find out the dam thing burns oil and I continue to have to watch and always add oil. I feel Hyundai needs to recall and fix the problem.

Sonata Sport 2.0 Limited

  • Automatic transmission
  • 64,321 miles

Car ran out of oil and ruined my turbo. Brought to Sterling Hyundai in Lafayette, LA. They told me they did not know why it ran out of oil and the turbo was covered under warranty so they changed that. Since then, I've brought it in multiple times for oil changes and mentioned every time that they needed to find out why it keeps consuming oil. I have to carry oil in my car. They tell me the same thing every time.

The last visit, they told me the warranty was up on my engine. Came home and checked and it is not up. I have 100,000 miles or 10 years on my engine. When I got mad, one of the workers came whisper to me that it wasn't just me, it was the car. So, they basically have been lying to me since January of 2020.

I am in the process of trying to file a complaint with Hyundai Motor to get a new engine. Not having much luck as of yet. Refuse to bring my car back to them.

Sonata 2.4L

  • Automatic transmission
  • 61,942 miles

My Sonata Sport was using a lot of oil, and when taken to the dealer where I bought the vehicle, I was given nothing but excuses. I had the valve cover, timing chain cover and oil pan resealed at 79,860 miles. Skip ahead to 1/26/22, when my car began sputtering at a VERY busy intersection. I checked the oil, and it was barely touching the dipstick. With only 1,540 miles on it since my last oil change. I added oil and contacted consumeraffairs@hmausa.com. Tony from Hyundai contacted the dealer I purchased the vehicle from and Tarr Hyundai in Morristown, TN stated my warranty was now out and I would be responsible for 100% of repair costs to fix an engine that has known problems with Hyundai. Had they repaired my engine when the problem first started, or even 1 of the 11+ times I was there for the problem, I would still be WELL within the very expensive extended warranty I purchased when I purchased my vehicle. I have owned Hyundai's for 28 years, always swore by them, and my dad even purchased one. But this car has ruined me on Hyundais.

Sonata SE 2.4L

  • Automatic transmission

The car burned 3 quarts of oil in between oil changes with only 66,000 miles on it. The issue started at about 40,000 miles but of course Hyundai being Hyundai, they just swept it under the rug and did nothing about it. Now my warranty is expired and I’m SOL. The rest of the car was starting to fall apart too, so I just ended up selling it to Carmax because I didn’t want to deal with it anymore. This was my first and last Hyundai.

Sonata Sport 2.4L

  • CVT transmission
  • 90,000 miles

Hello. I have 2015 Hyundai Sonata Sport 2.4l with excessive oil consumption. I bought this car used with about 15,000 miles on it. It takes me everywhere I need to go, and the car runs great as far as reliability. The first major problem I had is that the transmission failed at 99,000 miles which was covered under warranty, so I didn't pay out of pocket. My other issue is the engine consumes a lot of oil, probably a quart every week. This oil consumption started around 100.000 miles. It has an eternal engine oil leak somewhere, so I just deal with it.

The car now has 151,000 miles, so it's not worth fixing, but other than that it runs great. I just have to keep oil in my trunk, I'll just end up trading it in for another vehicle, not Hyundai brand.

Sonata Sport 2.0L

  • Automatic transmission
  • 58,000 miles

I've been informed by corporate Hyundai and local dealership that I will have to " wait it out" before they will repair vehicle. I'm concerned about my safety and family.

My car currently has 65000 miles and dealer believes I'll get about 25000 to 30000 more miles before car will qualify for engine replacement. Currently, it is using 1quart per 1500/2000 miles. Hyundai policy is oil consumption must exceed 1 quart per 1000 miles. I have that in writing as per their service bulletin.

Needless to say, I'm unhappy dealing with this problem. I wouldn't have bought car if I knew the engine was defective. I have a lot of anxiety and, recently, rented a car for out of town trip. I'm not sure what I'm going to do........really wish Hyundai would give us options. I'm really stuck at this point since I'm not able to sell or get full value of my vehicle.
