2020 HYUNDAI PALISADE Complaints

On August 14, 2026, while driving and decelerating, I heard a knocking sound from the engine and the vehicle had difficulty downshifting. As the transmission shifted from second gear to first, the engine stalled immediately and the vehicle dropped into neutral while on the roadway. I lost propulsion in traffic. The vehicle behind me nearly rear-ended us due to the sudden stall. My children were in the vehicle. All dashboard warning lights illuminated at the moment of the stall. I was able to restart the engine and move the vehicle slowly, in first gear only, into a nearby parking lot. The check engine light came on at that restart and has remained on since. The vehicle sat parked and off for approximately 90 minutes. Before restarting, I checked the engine oil level and it was within the normal range. On startup, my children and I both heard a loud knocking sound and noticed an unusual smell, and the engine idled roughly while in Park. I drove approximately 15 minutes home with the rough idle continuing. On arrival the vehicle smelled hot, with a burning odor, although the temperature gauge read approximately mid-scale and was not in the high range. The check engine light remained on and the oil level was again confirmed to be within range. The vehicle has been out of service since the incident and is currently at a dealership awaiting diagnosis. This is a 2020 Hyundai Palisade with approximately 93,000 miles at the time of failure. A sudden loss of motive power in a travel lane is a safety defect.

The paint on the roof of my 2020 Hyundai Palisade is peeling off in large sheets, rather than typical chipping or wear. The peeling originates from the center of the roof and has begun spreading toward the area near the front windshield edge. This is not consistent with normal wear and tear, curb rash, or impact damage — the affected areas show clean separation of paint layers down to a lower coat/primer, consistent with a manufacturing defect in paint adhesion or application. Rust is beginning to be visible. Based on research, this appears to be a widespread issue among other 2020 Hyundai Palisade owners, many of whom report similar peeling on roofs, hoods, and wheels, suggesting a systemic paint defect rather than an isolated incident.

My 2020 Hyundai Palisade (3.8L GDI Lambda II V6) consumes engine oil at a rate that empties the crankcase between scheduled oil changes, with no warning lamp illuminating before the oil is gone. This creates a risk of engine seizure and sudden loss of motive power in traffic. The vehicle has repeatedly run rough and felt as though it would stall when slowing or stopping. On 3/10/2025 at 57,026 miles I brought it to a Hyundai dealer because it felt like it was about to stall at traffic lights. The technician found no measurable oil on the dipstick, 4.5 quarts low, and found the camshafts out of time as a result. On 11/25/2025 at 69,851 miles the oil light flickered and the engine ran rough and stuttered. The dealer checked the dipstick and again found no oil on it at all. This was only 5,614 miles after a documented oil and filter change performed by that same dealer. No warning illuminated until the crankcase was already effectively empty, which I consider inadequate warning of imminent engine failure. Consumption has continued and worsened: 1 quart low at 77,202 miles (4/22/2026), 1.5 quarts low at 81,350 (5/14/2026), and 1.2 quarts low at 82,927 (8/11/2026), the last only 1,577 miles after an oil change. Hyundai TSB 23-EM-008H sets the failure threshold at 1 quart per 1,000 miles for all gasoline engines. The dealer twice billed Hyundai operation code 21000FCC, which that bulletin defines as payable only after an initial oil consumption test result of NG (failed). Two combustion chamber cleanings were performed at Hyundai's expense (1/2026 and 5/2026). Neither resolved the consumption. On 5/14/2026 the dealer submitted a request to Hyundai Motor America to replace the engine. Hyundai denied it verbally and has provided no written decision, case number, or reason. This is our family's primary vehicle and remains in service. I must check the oil weekly to keep the engine from running dry. Complete dealer service records are available.

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.

I believe this is related to RECALL 235, Veh was parked on the street, thank god. The Palisade then spontaniusly caught fire, fire department had to be called and insurance company says its a total loss. Fire started in the rear driver side.

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.

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)

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.

In addition, the contact was informed that the driver's side sunroof arm deflector was fractured. The dealer attempted a temporary repair using tape, but the failure reoccurred. The vehicle was taken back to the dealer, and the dealer reapplied tape, but the failure reoccurred. The contact stated that the temporary application of tape and debris had detached. The force of the wind caused the driver's side sunroof arm deflector to detach. In addition, the contact stated that the loud sound and the debris from the sunroof were over the contact's head. In addition, the contact's minor child was an occupant of the vehicle at the time o

Hyundai Motor America has been notified of the safety issue through the Mississippi Attorney General’s Office, which required Hyundai to provide a written response within ten business days. Hyundai has not responded to the Attorney General, has not responded to follow-up attempts, and has not provided any guidance or corrective action. The local dealership reports that Hyundai Corporate will not authorize warranty diagnostics or repairs, leaving the vehicle in an unsafe condition with no manufacturer support.
