2020 Hyundai Palisade problems

UNKNOWN OR OTHER

I am experiencing an issue with the power liftgate struts on my 2020 Hyundai Palisade SEL that appears to be a common problem among other Palisade owners. The liftgate support struts are beginning to fail, causing the liftgate to no longer stay fully open. When the liftgate is opened, it slowly falls back down instead of remaining securely in the fully open position. The struts appear to have lost their ability to properly support the weight of the liftgate and are essentially failing. This is particularly concerning because the liftgate can unexpectedly fall while someone is loading or unloading the vehicle, creating a potential safety hazard. Given the number of similar complaints from other Palisade owners, this appears to be a recurring issue with the liftgate struts. I would like Hyundai to recognize this as a potential common defect and provide a proper repair or replacement of the failing liftgate struts.

POWER TRAIN

This vehicle has suffered two identical, catastrophic electrical failures causing an immediate and total loss of engine power while traveling at highway speeds. The first incident occurred after the engine was replaced under a Hyundai extended warranty. The dealership service department blamed that failure on a loose engine ground strap and released the vehicle back to me. On August 3, 2026, the exact same failure occurred for a second time while driving at high speed on the highway. The vehicle lost all propulsion, leaving me exposed to oncoming traffic with zero engine power. The vehicle was towed to a Hyundai dealership. The dealership identified a blown "Sensor 4" fuse causing an intermittent dead circuit, but they have been unable to locate the short circuit after two weeks of troubleshooting. After demanding the diagnostic data logs, the dealership abruptly halted all repairs and ordered me to pick up the vehicle. Furthermore, due to excessive, repetitive diagnostic cranking and idling in 90+ degree heat while under the dealer's care, the vehicle's starter solenoid has now suffered collateral failure. The vehicle is currently completely disabled, undrivable, and the underlying highway stalling hazard remains completely unresolved. This is a recurring, severe life-safety issue that leaves the vehicle prone to sudden stall events in high-speed traffic without warning.

SEATS

In my 2020 Palisade with automated third and second row seats, the third row automated seat button was accidentally pushed and started to close on my grandchild who was sitting in the third row. The seat did not detect that anyone was sitting in it and kept closing. Luckily I was able to hit the button to stop it. This same problem also happened in the automated second row seat with a grandchild in it. Another [XXX] old child pushed the button on the entry side of the captain’s seat and the seat did not detect that there was someone sitting in it and began to close on them. Once again we were lucky and was standing there and able to push the button to stop it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER

Sunroof was opened and a slim metal piece fell down into the car landing in the console. I wasn’t sure where it came from so I tried to close the sunroof. It would slide to close but would not go down the last inch or so on the back. I tried to open and close it a couple times to see if it was just sticking and another slim metal piece fell down. I am afraid to drive much and over 25-30 mph because I am afraid the roof may fly out. A long silver piece was flopping around (I assume a wind deflector) so I laid it in the backseat. It’s a shame that I have a vehicle that’s basically unusable on rainy or windy days and can’t drive over 30 mph because roof may fly out and hit someone. I also cannot lock and set alarm because roof shows open and horn blows. I care for my elderly parent with dementia so this is not helpful when nearest doctor visits or Hyundai dealer is minimum 45 minutes away drive.

ENGINE

On or about XXX I brought my vehicle into the dealership as my 2020 Hyundai palisade suffered a severe, sudden engine malfunction while driving at highway speeds. The vehicle began shaking violently, losing power, and making loud mechanical noises forcing me to navigate dangerous highway traffic to get it to the dealership. Prior to the failure, in XXX, the vehicle was brought into an authorized dealership as the vehicle would not drive properly, very slow acceleration and the vehicle feeling like it was stalling causing a danger to the road. . The dealership performed an inspection on the vehicle and diagnosed "carbon buildup due to mileage and age," they performed an authorized emissions software update, changed the oil, and performed a paid fuel injection cleaning. The dealership did not issue a safety warning or advise against driving the vehicle long distance back to [XXX]. A few months after this service, the vehicle suffered total engine failure. Professional teardown of the Hyundai Lambbda ll V6 engine show that unresolved carbon buildup and software defects lead to piston ring failure, severe misfires, oil starvation, and sudden loss not motive power. Operating a vehicle experiencing severe mechanical shaking and power loss at highway speeds poses an immediate risk of an accident.

When attempting to use engine braking to control descent on mountain roads, the vehicle failed to slow. Engine RPMs increased and speed increased requiring significant brake usage. Last year the vehicle performed as expected as deceleration was controlled via downshifting with much less brake usage. The only change was the application earlier this year of Hyundai service campaign 9C9.

ENGINE

The vehicle suffers from a severe manufacturing defect causing excessive engine oil consumption (burning more than 2+ quarts per 1,000 miles) with no warning lights or oil pressure indicators activating. With little to no warning, I could be driving and experience catastrophic engine failure. This defect creates an immediate safety hazard, as sudden engine seizure or stalling at highway speeds risks loss of power braking and steering, creating an imminent risk of a high-speed collision. The dealership has confirmed the oil consumption issue after we noticed the vehicle stalling and performing sluggishly until the oil was changed.

I bought this car used from Albion Ford and I didn't have it 3,000 mile when my check engine light came on. Took it in and they said nothing was wrong with it. A couple days later it stalled in the middle of the road at a stop sign. It happened a mile later, I stopped at the store and there was absolutely not oil on the dip stick. I put 2 quarts in and it was at the very bottom of the dipstick. It's still under warranty and they did an oil consumption test and said it was normal. It's burning 5.5 quarts every 3,000 miles.
