2020 Hyundai Palisade

Check engine light came on and stayed on. When using heat for car it was not heating up well or to temp. Got in to be serviced 12/16/25-12/18/25. Replaced a plastic part in engine and said engine was not heating up like it should. Cost $814. Reset check engine light. On 1/2/26 reversed car out of driveway into street and car came to abrupt stop and would not shift into any other gears. Another vehicle was coming up the street and almost collided with us and I could not get my vehicle to move which was blocking the road. Warning message said “Shifter System Malfunction: Service Immediately.” Pushed power button to turn off vehicle. Turned back on and able to get into drive to park back in driveway. Definitely having electrical issues and multiple problems with car since October 2025 when weather became colder for winter.

Issues began in November of 2024 Began with a a oil consumption test and failed. Submitted for a new engine due to high oil consumption 3 quarts in 1,000 miles. Waited 6 months for a new engine to be available. July 2025 noted oil leaking brought in for repair and stated it was a boot joint that was leaking. Multiple return trips to repair since oil was still leaking. Check Engine light came on in , September and a faulty sensor in engine was noted (for mixing air and gas?), replaced sensor. Oil still continues to leak and after insisting they take the entire engine out to figure out where it was coming from a leaking faulty oil plug was noted on the rear side of the engine.

I am the 3rd time owner of this palisade. Car was bought after a transmission replacement at 27,000 miles. (Second transmission). At around 70,000 miles, we started to have oil consumption problems/ignition coil problems. After a slew of tests and other recommend procedures that cost us money out of pocket, hyundai recommended to get a new engine. We get the new engine. They call to tell us the new engine is done, and proceed to share the transmission is bad and it needs a new one (3rd transmission). They are asking us to pay for the transmission as well. We want a buy back as we think this is a lemon car. 3 transmissions and a new engine under 85000 miles is not good and definitely grounds for investigation. These repeated failures make it unsafe/unreliable for us to drive our 6 month old baby in, let alone my wife and my myself. . We request and investigation/buyback.

The vehicle experiencing excessive oil consumption without any external leaks. Since February 2024, I have repeatedly reported this issue to the dealership. They required me to complete multiple 1,000 mile oil consumption tests and eventually performed a combustion chamber cleaning. Despite this, the oil consumption problem continues. As of today, after driving only 3,700 miles, the engine oil level was so ow that the dipstick did not register any oil at all. No warning lights or dashboard indicators ever came on to alert me to the low oil level. The dealership has acknowledged my concerns but stated that Hyundai considers this "normal specs". I strongly disagree, as the amount of oil being consumed poses a safety risk if the engine fails while driving. The problem has been confirmed by the dealer during inspections, but no permanent repair has been offered. The ongoing issue creates a serious risk to both my safety and the safety of others on the road due to potential engine failure from lack of lubrication.

Safety Complaint Summary: I am filing a safety complaint regarding my 2020 Hyundai Palisade SEL AWD, ~96,000 miles). This vehicle has suffered three major powertrain failures under 100,000 miles: - Full engine replacement (due to excessive oil consumption, unresolved for months) - AWD system repairs - Now requires a full transmission replacement When my engine began burning oil, Hyundai’s service department charged me ~$500 and sent me back on the road without disclosing that this was a known issue. I continued running out of oil multiple times until an independent mechanic diagnosed the defect. My family was unknowingly placed at risk while Hyundai delayed resolution for 8 months. Diminished Value: The repeated nature of these failures not only raises safety concerns but has also destroyed the market value of the vehicle. Even after a transmission replacement, the Palisade remains a car that no buyer would trust — which underscores the seriousness of these systemic safety risks. Relief Requested: I ask NHTSA to review whether this defect pattern represents a broader safety issue and whether Hyundai should have disclosed the known oil consumption defect earlier and should investigate why a vehicle is suffering three powertrain issues and if this is a wider problem with the car type/year. A notice to consumers should be issued so we are not driving around in an unsafe car.

The contact owned a 2020 Hyundai Palisade. The contact stated that while driving at approximately 65 MPH, he heard an abnormal popping and hissing noise. The contact stated that he started to smell a burning odor. The contact was losing forward momentum. No warning lights illuminated. When he applied the accelerator pedal, the vehicle continued to slow down. The contact pulled off the highway, stopped the vehicle, and turned off the engine. The contact stated that almost immediately, smoke was issuing from under the front end. The contact stated that the vehicle burst into flames. The police and fire department were called. The fire was extinguished using chemicals. The police and fire departments issued reports. The vehicle was towed away to an impound lot. The contact stated that he had the transmission replaced in 2024. The manufacturer was not informed of the failure. The failure mileage was approximately 150,000.

While merging onto a highway, my 2020 Hyundai Palisade abruptly lost all engine power and stalled. This immediate and complete failure occurred at a critical moment, posing an extreme safety risk. All dashboard warning lights illuminated, but provided no specific diagnosis. The vehicle was towed to a dealership, where technicians determined the engine was consuming oil at an abnormal rate, despite a lack of visible leaks. I was instructed to participate in an "oil consumption test," a three-part process that required multiple oil changes and inspections over several months. Each time, the vehicle had burned over a quart of oil—a clear indication of a defect. Despite this evidence, Hyundai denied my warranty claim, accusing me of negligence for being unable to produce oil change records between 29,600 and 46,900 miles. This is a common and unacceptable tactic used to avoid accountability for a widespread issue. My experience is not isolated. Hundreds, if not thousands, of owners of 2020-2023 Hyundai models, including the Palisade, report identical engine oil over-consumption issues and subsequent power loss. This issue is a **severe safety hazard** that can lead to sudden, catastrophic engine failure and potential accidents. Hyundai's refusal to acknowledge this defect and issue a recall is **gross negligence**. They are knowingly allowing thousands of unsafe vehicles to remain on the road. There are currently federal lawsuits against Hyundai for this very issue. The transportation authority must force Hyundai to issue an immediate recall and remedy this critical defect before a tragedy occurs.
