2020 Hyundai Palisade

My car has been diagnosed, by a dealership, with excessive oil consumption due to a faulty piston ring which caused there to be no compression in cylinder 1. Initially my car had smoke coming from the tailpipe, then it started to shake while idling and the check engine light came on (delearship cleared it), then it overheated on me while going down the road with no warning whatsoever. Each time there was no oil on the lipstick. This is dangerous for people to not have any warning as to when the car is going to overheat until its already overheating. It could potentially set on fire while going down the highway with my [XXX] and [XXX] old. As soon as I put oil in it, it runs totally fine. I have voice recordings to confirm the diagnosis.

This vehicle has excessive oil consumption, and the low oil light does not light up to tell you that you are low on oil. I only noticed that I was low on oil because the engine starts knocking and started to stall. I had the oil changed according to all service intervals and at one point the dealership told me my car had no oil left in it. I just had it changed, drove about 2k miles and already had to put more oil in because it didn't even show any oil on the dip stick. This is a safety hazard as well as an environmental problem with these vehicles burning this much oil. This started happening around 80-90k miles on the engine.

Over the past 5 years, this vehicle has experienced three major powertrain failures: two complete transmission failures and, most recently, a catastrophic engine failure. The most recent issue involved the engine burning excessive oil without warning. While my wife was driving downhill, the vehicle shut off completely, causing a total loss of power steering and braking. She was barely able to get it safely to the side of the road. It was a serious safety risk, especially with children in the vehicle. Each failure has occurred well before it should in terms of mileage, and despite repairs, the issues continue. After this third failure, Hyundai offered to cover only 50% of the repair costs—which seems to acknowledge some degree of corporate responsibility—but we declined, as this is a relatively new vehicle and the problem is clearly systemic. We paid the second total transmission replacement completely out of pocket. A quick Google search and outreach to social media revealed that hundreds of Hyundai owners (across multiple models from this era) are experiencing very similar engine issues, many with official recalls for consumption, but there being no official recall or widespread support for Palisade owners. Personal stories suggest a clear pattern. The original dealership that sold the vehicle listed it as Certified Pre-Owned, but has since changed ownership and retains no records, which has made verifying the warranty status impossible. Hyundai corporate and customer service have been extremely difficult to work with—there are multiple active case numbers, no internal communication, and the local dealership doesn’t coordinate with national reps. This vehicle has spent over 100 days in service across these failures. I’ve tried every route available—dealership, corporate support, and online forums. The community is unsafe, and without broader action, other families could be at risk.

In short, the transmission has been replaced, the fuel injectors and other components. After that gets fixed they are saying we need a whole new engine and hyundai with only a pay a portion of it. We did the oil consumption test and it failed. The car was down for almost two months and they want us to pay 6k as our part. This is absolutely ridiculous and this seems to have been a known issue.

Hello, I have a 2020 Hyundai Palisade that was bought last year in 2024. It’s had no issues with the engine up until approximately the last 2 weeks with oil consumption and noises from the engine rattling. I contacted the dealership to get it checked out and on the way there it caught fire. The engine died and almost all of the oil leaked out. The engine block now has a hole in it, so it is unable to be driven. My husband was driving and had just had surgery. Thankfully I was driving in a separate vehicle with my kids in case something like this happened. It has been sitting at the dealership since the 28th of May. The dealership inspected it and said there is no known cause at this time. The dealership also said they unfortunately can’t do anything. I called my insurance and they said the only thing they can cover is the damages caused by the fire. The estimate amount to fix it is 13K. But I believe the engine malfunctioned and was already having problems without my knowledge of it. There were no warning lights or alerts stating there were any problems with the vehicle. I also do know there is a class action lawsuit happening because of the 2020 Hyundai Palisades.

UNKNOWN. Rough idling. Throwing itself into park & turning the engine off but dash stays on like engine is running. Engine, oil, battery, theft light does come on when this happens but go away after starting car. Has been to mechanic multiple times but showing no codes & unable to figure out the cause of it. The car can not just idle either. Has been going on for over 6 months.

Experienced complete engine failure. Car was at a Certified Hyundai dealership 2 weeks prior for new plugs and new coil pack. Multiple point inspection with no noted issues. Driving on a 3 hour trip when suddenly the engine started knocking without an engine light or oil light coming on. Pulled over and no oil on the dip stick. The same dealership did an oil change at 86,000 miles now the car has 92,000. No oil change suggested at last visit. Sounds very similar to other recall descriptions. Please review

I am writing to formally submit a complaint regarding my 2020 Hyundai Palisade, which has experienced a sudden and complete engine failure. This issue poses serious safety concerns and appears consistent with widespread reports of engine-related defects in Hyundai vehicles. I purchased this vehicle in 2023 from CarMax as a used vehicle, and at the time of purchase, I signed all necessary documents, including the federally required Lemon Law Disclosure form. This document is intended to protect consumers and ensure transparency about any known issues or potential defects associated with the vehicle. At no time was I informed that my vehicle may be subject to engine-related concerns that could result in total engine failure. Recently, my Hyundai Palisade’s engine failed, requiring a full replacement. I have discovered that Hyundai has issued multiple recalls in recent years related to defective engines in various models due to manufacturing flaws that can lead to knocking, stalling, or engine seizure—all of which create serious safety hazards. Although my vehicle is not currently listed under a recall, it is highly suspicious that I am facing the exact same problem affecting thousands of other Hyundai owners. This situation is unacceptable and undermines consumer trust. I urge the NHTSA to investigate whether the 2020 Hyundai Palisade should be included in existing or new recall campaigns related to engine defects. No consumer should bear the burden of an expensive engine replacement when manufacturer defects are clearly a pattern within the brand. Please advise me of any steps I can take to formally escalate this matter and ensure Hyundai is held accountable for this serious failure.

The vehicle has an engine flaw, which caused the vehicle engine to stop running while I was driving down a busy highway to take my children to their activities. The traffic behind me nearly slammed into the back of my Hyundai Palisade because the engine cut off without warning. There was no indication of engine trouble, no dashboard lights, no warnings at all. All the preventive maintenance was performed at the dealership, including an oil change only one month prior to this incident. Turns out the engine cut off because of lack of oil. Now I am finding out from the dealership and the manufacturer that the engine does have a known Oil Consumption issue causing the combustion chamber to need cleaning before and beyond a preventive maintenance schedule. But there still needs to be a warning light or something to inform the driver about the potential engine cut off. It is unsafe to drive, and unfair for the owner to pay for this manufacturer flaw.
