That's a lot of oil use in a short time period. That literally is almost fill the oil and check the gas.

Reminds me of my first car, a 1939 Chrysler bought in 1962 for $50.00.

Well I got my car back today, they at least found a source for the oil leak - leaking through the oil FILL hole ????
Now they can start with the consumption test, in two weeks I will be bringing the car in again.

The oil drain plug was out as the tech filled the cylinder(s) with fresh oil. The oil in cylinder 5 leaked past the rings over time to the crank case and out the open drain hole confirming a problem with that cylinder below the head, ruling out a bad valve guide or seal. Hang in a bit, you'll get a new short block after the consumption test in all likelihood.

Interesting way they troubleshoot that... They can easily do a compression or a leak down test on that cylinder.. If it's not holding pressure, then there is a leak. Air is much thiner than oil. If it passed on air, there is no way oil will leak.

All:

First time poster, but I think it’s important we have a thread on an issue that seems to be percolating with the Palisade. As the title suggests, I have an excessive oil consumption issue.

The problem started approximately 9,000 miles with a check engine light and some misfiring. Took to dealer and they advised me to change oil. Fine, that’s what we did. They also said come back at 14,000 for another change. So, that’s what I did.

At 14,000, I got another oil change and was told it was a little low. But, didn’t seem to be enough to warrant concern and not enough to notate on the file. Fast forward about 3,500 miles.

At 17,500, check engine light, misfires, and stalling out at every stop sign and traffic light. This is a family car with small children/infants that my wife is taking around town. Stalling out at every stop with family in tow is clearly a major problem in our household.

Take it in to dealer. Turns out, it’s 4.5 quarts low after 3,500 miles. Well, that certainly doesn’t seem to be within the band of any reasonable oil burn rate I have ever heard of for anything with a combustion engine on this planet. Nevertheless, the dealer swears theirs hands are tied and they have to start the oil consumption test.

I’m told to bring it back every 1,000 miles for the next 3,000 miles. They will check the level and send the results off to the bean counters at Hyundai corporate so that somebody that doesn’t have their family on the road in a stalling vehicle can determine whether this safety hazard actually has a problem or not.

So, today was the first 1,000 mile. Took it in and it is 3.5 quarts low after only 1,000 miles.

Are they fixing it? No. I’ve still got to go through this corporate protocol. I did call the 1-800 number and open a case file. But, that hasn’t fixed my car yet.

Curious what other similar problems folks have had. This has become an unusable $50K piece of metal at the moment.

Dealership states that in 2023 it is known fact that Palisade burn oil. Apparently, 1 quart per 1,000 miles is acceptable to them. If it burns more than the 1qt per 1,000 miles they will perform a combustion cleaning and repeat tests to see if it exceeds the 1qt per 1,000 miles. If so, then they will open case for Hyundai to replace the engine. That's wholly unacceptable to me; guess I will move to cheaper oil and filter and change/replace oil every 5K miles and perform combustion cleansing every other oil change.

Definitely some sort of Engine issue. Did you open a claim with Hyundai corporate? Also Lemon law if you do mot get satisfaction. No fun. Most of us been very happy. Wish you luck.

I'm having the same issues with Hyundai palisade buring to much oil.. under 1,000 miles low runs rough Do I need open up a claim with corporate?

Hi, This Curtis . I have a Hyundai Palisade 2020 I'm at 99,123k.. and having consumption of oil Bruning. I have open up a case # waiting on them returned my call.. " You mention most of yall been happy ?? What the outcome after putting ur claim corporations??

Please reply back thank!

Well I had a most satisfying experience. After I could arrange for the first oil consumption test, they confirmed my own observation of 2 quarts per 1'000 miles. They got on the phone to Hyundai Corporate and decided on the spot that I did not need to do the second and third test, as the engine had clearly failed. They got the approval for the new engine within a couple of days and it actually showed up at the dealer within a week (they are not always told in advance what shows up on parts I was able to take a peek on the parts list they sent to the dealer, quite a lot of stuff, priced at $26k - half the price of a new Palisade. During the down time I got a rental and a new Santa Fe to drive (had to get the car back to tow my boat to the water!). So all in all, about as good an experience as you can imagine. Btw, there is no warrranty extension on the new engine, I have 45k and 3.5 years left on the original warranty - but they told me that Hyundai is quite accomodating for issues arising after the warranty expires in such cases...

 

[curtislyoung993]

Thanks! For information.. I just did the 1st consumption test They told me they have to keep it overnight I guess they have to clean the valves because I don't have no leaks.. not sure where the oil is going in two weeks I'm down 5qurts smh

 

[blackberry.chm]

They needed my car for a few days too after it failed the test, they documented a bunch of stuff and made some pictures for the submission to HQ... then they got the ok for the engine swap..

The importance of unclogging a catalytic converter cannot be overstated. The catalytic converter plays a vital role in reducing harmful emissions from a vehicle's exhaust system. It contains a catalyst, typically made of platinum, palladium, and rhodium, which helps convert toxic pollutants into less harmful substances.

Over time, the catalytic converter can become clogged due to the accumulation of carbon deposits, oil residues, and other contaminants. When the converter is clogged, it restricts the flow of exhaust gases, leading to several negative consequences:

1. Reduced Performance: A clogged catalytic converter restricts the exhaust flow, resulting in decreased engine performance. This can lead to reduced acceleration, lower fuel efficiency, and an overall sluggish driving experience.
2. Increased Emissions: When the catalytic converter is clogged, it cannot effectively convert harmful pollutants into less harmful substances. As a result, emissions of nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC) can increase, contributing to air pollution and environmental damage.
3. Engine Damage: A severely clogged catalytic converter can cause backpressure, which can lead to increased heat and strain on the engine. This additional stress can damage engine components over time, such as valves, pistons, and exhaust manifolds.
4. Check Engine Light and Failed Emissions Tests: Modern vehicles are equipped with onboard diagnostics that monitor the performance of the catalytic converter. When it detects a problem, it triggers the check engine light and may even cause the vehicle to fail emissions tests, resulting in le

I have a 2020 Palisade with 80,000 miles on it. Lately, it's been using an extra quart of oil every 1,000 miles, even though there aren't any visible leaks. The vehicle has also stalled twice, similar to issues reported by other owners. Despite five visits to the dealership for 500-mile oil consumption tests, Hyundai maintains that the oil consumption is within acceptable limits. I provided the dealership with documented complaints from other owners and also highlighted a class-action lawsuit found at mycarvoice.com/news/lawsuit-hyundai-oil-consumption-nu-gamma-theta-lambda-kappa-engines/#google_vignette

The service manager said the most common reasons could be:

1. Worn Piston Rings: Over time and mileage, the piston rings in an engine can wear out. When this happens, oil can get past the rings and into the combustion chamber, where it's burned and expelled through the exhaust.
2. Valve Seals or Valve Guides: Worn or damaged valve seals or valve guides can allow oil to leak into the combustion chamber.
3. PCV System: The Positive Crankcase Ventilation (PCV) system can malfunction, which might cause oil to get sucked into the engine and burned.
4. Oil Leaks: External oil leaks are a possibility. You might see spots of oil on the ground where you park. Common leak sources include the valve cover gasket, oil pan gasket, oil filter, oil cooler, and the oil plug.
5. Engine Wear or Damage: An engine that's been damaged (due to overheating, lack of oil, or other factors) can have increased clearances that allow oil to escape into the combustion chamber.
6. Frequent Short Trips: Engines that are frequently started and stopped, especially in cold weather, might not reach optimal operating temperature. This can lead to incomplete combustion and increased oil consumption.

The service manager advised against keeping the car, stating that Hyundai won't address the issue. This may eventually lead to the engine failing or not passing the emissions test. Consequently, Hyundai has lost a loyal customer while class action lawyers have gained one. It's truly disappointing how Hyundai has handled this situation.

Update: Was told that the original oil consumption test was not documented correctly so I had to start over......I have been doing this since May! Said I could not because I was Driviing to Florida (from Chicago). The trip was going to be about 3000 miles. they were unwilling to give me a loaner and said the car was safe to drive and bring it in when you return. I checked the oil every 1000 miles and after 2600 miles finally saw a dip in the oil level./ it was about a quater below the F on the dip stick. Car ran great during the trip while averaging 26 MPG! Last 400 miles were city driving when I got back to Chicago. Just before bringing back to the dealer I check the oil 1 last time. It was close to 1/2 full after 3000 miles. I dropped it off 11/4 And had to call MULTIPLE TIMES to get an update. My local service Department is beyond awful. Finally heard back from them today and they said they are waiting to hear back from Corporate. Back to thinking I am not going to see my Palisade for a while. I will send an update when I hear more.

Update- Sorry for the delay..... After 4 or 5 consumption tests, the issue finally produced a error code and a check engine light! CAM #3 was locking up. at 53K miles Hyundai agreed to a full engine replacement. Had the engine swapped out in 3 days and 12K miles later no more issues. Drove back down to Florida and no more oil consumption! It was a long, painfull, frustrating road but Hyundai eventually fixed the issue! Good luck to all experiencing this.

Thanks for the follow up. Something more folk that post issues should do.

We bought a 2020 palisade from Hyundai of the Carolina’s in high point nc. At 63,000 miles the car started running rough. We checked the oil and it happened to be 3 quarts low. So we called the dealership to come get the car and take it to their dealership shop and see why it’s leaking. It took 4 days to finally get the car there. Once it was there they looked through everything and decided it was time to do an oil consumption test. They filled the car with oil and instructed us to bring it back every 1,000 miles for 3 times. After this was completed they told us we were using 3 quarts of oil every 3,000 miles. So that’s 1 quart of oil every 1,000 miles. We were told that’s normal by Hyundai’s standards and that we had to call some 1800 number and have a case mananger. After waiting nearly a month to get ahold to someone they finally called back and said that our case was normal oil consumption and there was nothing that could be done. I’m no mechanic but I know damn well a vehicle, especially one with 63,000 miles, should not be using a quart of oil every 1,000 miles. I hope whoever reads this will never buy another vehicle from Hyundai and especially don’t buy one from Carolina Hyundai of high point nc. They tell give us a 100,000 mile warranty but won’t honor it when something goes wrong. If enough of us can get together with the same issues and file a class action law suit then maybe they would do something about it. Boycott Hyundai !!

Boycott Hyundai !!

I suspect it's a little late for that advice on this forum, eh?

 

[Palisade_2020]

@cpeshoff59, In our instance, the vehicle maintained an intact oil level until the 82,000-mile mark, with regular servicing exclusively at Hyundai. Yet now, it consumes 1 quart of oil every 1000 miles, a phenomenon we are informed is commonplace. However, the question arises - if this is indeed a 'normal' occurrence, why did it manifest only after 82,000 miles? There has been a shift in the vehicle's operation. Despite having acquired an extended warranty that lasts up to 120,000 miles, the service manager recommended that we consider parting with the vehicle. I am extremely disappointed, and we love the car.
