Sonata GLS 2.4L

  • Automatic transmission
  • 95,000 miles

I have to keep adding oil to my car even after an oil change. I'm constantly checking to make sure I won't burn anything. I went to the dealer about the issue last year and they told me I just missed the warranty and will have to pay for tests to see how fast the oil is burning out - I couldn't afford it. It's crazy that I have to constantly buy oil for this issue. The other day a driver told me I had blue smoke coming out and I checked - my car was bone dry even though I had an oil change on 6/22/22.

Sonata GLS 2.4L

  • Automatic transmission
  • 100,000 miles

Last year, I started to notice oil was disappearing quite fast. I constantly have to watch oil every other day and when needed, even after an oil change.

I went to Hyundai where they told me that my warranty has expired and I would have to pay out of problem for testing. It's so aggravating especially when Hyundai know it's an issue.

Can someone reach out? I need this problem to be fixed.

Sonata SE 2.4L V6

  • Automatic transmission
  • 148,500 miles

The mechanics added oil because it was just a little low at that time. Didn’t think of it as a problem at that time.

But as time passed by, I was having to add oil from time to time.

I took it to the dealership after I realized it was a persistent issue. I was up to over 160k miles at that time. They originally told me to do a consumption test. But when I went back another rep said it was useless to do the consumption test because it was out of warranty.

I changed the PCV valve but it still continued to consume oil. Now today, the car stalled. I know others in my family who have oil consumption issues with their Sonata as well. This seems to be a persistent issue and failure for these engines.

Sonata 2.4L

  • Automatic transmission
  • 98,700 miles

I was told at South Point Hyundai in Austin Texas that when a Sonata reaches the range of mine, 98,700, it is normal to consume a quart every 1,000 miles. What a crock of BS. I have a 2003 Toyota Tacoma with 170,000 mile that does not burn any. My Sonata is part of a warranty extension to 120,000 miles due to problems during manufacturing. This sounds like a ploy to say it is normal to get past 120,000 miles.

If nothing is done, I will never have another Hyundai. So much for Korean integrity.

Update from Oct 29, 2019: I was told at Hyundai dealer that when a Sonata reaches the range of mine, 98,700, it is normal to consume a quart every 1,000 miles. Come on, I have a 2003 Tacoma with 170,000 miles that does not burn any. My Sonata is part of a warranty extension to 120,000 miles problems during manufacturing. Sounds fishy that all of a sudden, consumption is normal.

Sonata GLS 2.4L

  • Automatic transmission
  • 68,950 miles

I purchased the car from an individual with 45,000 miles on it and did my first oil change. My previous cars were all port injection, this was my first experience with GDI engines. Well, around 3 thousand miles, I checked my oil and it was down 1.5 qts and read about GDI engines burning 1 Qt every 1000 miles as NORMAL! I was using AMSOIL SIGNATURE SERIES OIL BY THE WAY!

To make a long story short I was buying 10 quarts of oil and a filter every 5k oil change intervals. I switched to PENNZOIL ULTRA PLATINUM used in all FACTORY Dodge HELLCAT ENGINES with 707 HP. I noticed the oil consumption got a LOT WORSE, now at 68950, as it now burns a Quart every tank of gas around 330 miles, this will be my third trip to the dealer for my 3 strikes oil test. The service manager said it WAS NOT UNDER WARRANTEE FOR THIS ISSUE!!!!!!

I have had the software update and knock sensor changed for the bearing issue. I was so mad that he would not stand behind this engine piston ring failure that I called Hyundai and I am waiting for them to call me back with a case worker to address the issue, as it is ANOTHER well known problem, not as prolific as the engine seizing issue. By the way, the Pennzoil ultra platinum should hold up to Florida temps and I am using 10w/30 because of the heat and it never gets below 40 here in Tampa Bay.

The service manager said to change my pcv valve but I checked it and it rattles and works fine every time. If that was bad I would be blowing oil out of my seals somewhere but have no leaks as I park it in a garage and no oil stains. Yes, I changed the Denso spark plugs out early as well as the trans fluid because of city driving demands.

Update from May 28, 2021: 4/21 i was required to do 5 oil consumption tests yes it's up to 5 now per HYUNDAI , well the best I did was 350 MPQ YES THAT WAS 350 MILES PER QUART ! Hyundai customer service rep said he could not do anything as it was shot down by the warrantee dept ! Long story short it started burning 1 qt every 1000 miles @ 45,000 and by the time I had 68,000 on the clock it was burning 1QT every TANK FULL ! GREAT ENGINE 2.5 L I put a catch can on it and it wasn't collecting any oil as I was using a very quality oil with low everapion rate (NOACK) i HAD used CRC INTAKE VALVE CLEANER at around 50k and again at 60k trying to prevent carbon build up and changed the oil right after. THE BOTTOM LINE IS THE RINGS ARE TOO LOOSE AND NOT SCRAPING OFF THE OIL, END OF STORY. Hyundai said it was not replacing engines for excessive oil consumption no matter how bad it was because I was the 3rd owner. AND THEY HAD THE Bearings TO TRY AND SELL ME A NEW CAR !

Sonata GLS 2.6L

  • Automatic transmission
  • 96,800 miles

Simple - I bought the car from Drivetrain Ocala Fl. All appeared ok then it all hit. First the brakes pad gone 500 miles after purchase then 60,000 miles - the oil was down to barely registering on the stick - no low oil warning light - NONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

96,000 miles - going through oil like crazy. Sonata should be called sh*t on wheels.

Sonata GLS 2.4L

  • Automatic transmission
  • 110,000 miles

The car started using about a quart every 500 miles, around 110,000 miles. Found out when I took the car in for a regular 3,000 oil change and the stick was bone dry. Checked oil religiously over the next two oil changes and realized that it was using oil at an alarming rate. Took it to the dealer to see if it was related to the engine recall. Their tests came back negative and the service manager said that level of oil consumption was within tolerance for that age of vehicle. Horse hockey. Unloaded the vehicle, trading it back to the dealer.

  • Automatic transmission
  • 30,000 miles

After my car continued to lose/burn oil ( was not leaking oil) I had my mechanic take a look and he informed me that i needed a new engine. My car will go about 700-800 miles before it almost completely runs out of oil. Took it to the dealership and they are having me do oil consumption tests. I am currently on my third oil consumption test. From what i understand it is standard procedure to do three oil consumption tests. I am suppose to bring my car in after 1000 miles to start the new test however my car never makes it to 1000 miles. The dealership has assured me that after my third and final test they will contact Hyundai and request a new motor. I just received a letter in the mail last week from Hyundai acknowledging an issue with the engine and engine components in the 2013 models and yet still i have to continue with the oil consumption test. So far it seems that my dealership does want to help me with the issue lets just hope Hyundai holds up their end of the deal since my car is still under warranty and now they have extended that warranty.

Sonata GLS 2.4L I4 Di

  • Automatic transmission
  • 124,000 miles

Engine started burning about one quart per 1000 miles, shortly after warranty ran out. Warranty was extended by Hyundai from 100,000 miles to 120,000 miles. The problem started at 124,000 miles. I bought the car as a 1 year old certified used vehicle with 18,000 miles on it. I've had the oil changed every 3,000 to 5,000 miles religiously. My mechanic told me that the car had burned most of its oil at a 3,000 mile oil change. He also said that there were metal shavings in the oil. THIS IS CONSISTENT WITH A PROBLEM THAT HAS BEEN WIDELY REPORTED ON THIS ENGINE.

Sonata Sport 2.4L

  • Automatic transmission
  • 30,000 miles

I have a 2013 Hyundai Sonata Sport with 30820 miles. Under heavy acceleration such as passing another vehicle or getting on the freeway, a cloud of blueish smoke billows from the exhaust, and the vehicle loses power. I took the car to the dealer, and the said I had to do an oil consumption test. I just had an oil change done 300 miles earlier, but the dealer needed to do another oil change to start the consumption test. I went ahead and paid for another oil change to start the test.

After 460 miles I took the car back to the dealer because the problem seems to be getting worse. The mechanic checked the oil and the car had consumed a third of a quart of oil. This is excessive for 460 miles. The mechanic topped off the oil and told me to come back after 1000 miles. I don't see how this makes sense since it could be making the problem worse, and end up resulting in an engine replacement. I was also told I need to do a total of three oil consumption tests before they move to the next step, which they said they don't know what that may be.

It is going to take a long time for me to put a 1000 miles on the car since I do not trust my Hyundai Sonata for longer trips out of town.

My research shows that this is a know problem with the Sonata, which to me points to a poorly designed engine.

Sonata GL

  • Automatic transmission
  • 37,565 miles

My engine has been burning oil. No one can find any leaks. First the dealership tried telling me that they must not have put oil in my car after my last oil change, or that I never got an oil change to begin with. They tried to pressure me into buying $430 worth of services immediately, said I had to pay them for another oil change and tried to tell me my engine air filter was never replaced when I, myself was the one who replaced it 7,000 miles ago. The problem with the oil continued. Next the dealership told me I had to do some oil consumption tests to prove the oil is disappearing. After 500 miles, it lost 1.3 quarts. After another 500 miles it lost 1 quart. After another 800 miles it lost 2 quarts. My car constantly smells like it is burning but the dealership refuses to fix it. I was told I have to do 1,000 more miles of oil consumption tests. After that they will do a compression test and go from there. I contacted corporate because I do not feel safe driving my car and I feel like I'm getting the run around. Corporate contacted the dealership and the dealership told them I have to do 3,000 more miles of oil consumption tests and that I passed a compression test. The dealership tells me one thing and corporate another and I still have the problem. I have gone in 5 times with this, they have noted that there is a major problem, but they wont fix it. It's covered by their warranty, but every time I try to get it fixed I'm presented with more hoops to jump through.
