2020 Hyundai Palisade problems

“• Noticed a rattle sound when taking off and when the car was preparing to stop; All timely maintenance were done at Headquarter Hyundai in [XXX]. Oil change was done by Tires Plus ([XXX]) end of XXX as the car was just over 100k miles, so no warranty. • XXX, notice the rattle sound and notice the engine tremble when stopping. Returned to Tire Plus for diagnostic. XXX - TECH NOTED NO OIL ON DIPSTICK UPON ARRIVAL. CUSTOMER ADVISED TO DO OIL CHANGES MORE FREQUENTLY AT 3,000 MILE INTERVALS; NO VISIBLE OIL LEAKS AT THIS TIME - INTERNAL ENGINE OIL CONSUMPTION. POTENTIAL PISTON RING OR ENGINE BEARING ISSUE CAUSING OIL CONSUMPTION. COMPUTERIZED ENGINE ANALYSIS. • My safety was at risk when the oil notification failed to occur, when the check engine notification failed to occur. These failures could have resulted in a complete shut down of the engine resulting in an immediate collision as I travel on the interstate daily for work.”

“AC FAILIRE IM SUMMER, just outside warranty but tsb issued. Holler Hyundai Service wants to charge me $350 diagnostic fee to take a look and diagnose. Extreme heat while having to use vehicle to go to work, run errands and transport children. No alternate vehicle is available and dealership is unreasonable to work with. Due to high humidity in Florida windows fog and hard to defog, visibility is impaired suddenly while driving”

“There is pre-mature failure of the rear shocks/struts. Vehicle is a 2020 Hyundai Palisade Limited with 70,000 miles on it. Normal wear and tear with no excessive use and never towed anything. Hyundai dealerships are backed up for service appointments. I was finally able to get in for an appointment, and they confirmed pre-mature shocks/struts failure but parts are on back order. The dealership states the vehicle is "safe to drive" but I am concerned. We are a family of [XXX] and are worried about a bad outcome with all the extra bounce in the car on [XXX].”

“My 2020 Hyundai Palisade is affected by NHTSA Safety Recall 25V607 / Hyundai Recall 283 involving the first- and second-row seat belt buckle assemblies. The recall was initiated in 2025, and my vehicle remains unrepaired approximately one year later. This defect has actually occurred in my vehicle. Seat belts have released/unlatched while the vehicle was being driven, creating a serious risk that an occupant could become unrestrained while the vehicle is moving or in the event of a collision. The Hyundai dealership documented Recall 283 as outstanding on my vehicle in March 2026. I returned to the dealership in September 2026, and the recall remained unrepaired because the required parts were unavailable. Hyundai Motor America has since confirmed in writing that the required parts are back-ordered. Hyundai states that a set has been assigned to my vehicle, but there is currently no estimated time of arrival. Approximately one year after this safety recall was initiated, my affected vehicle remains unrepaired despite the seat belt defect having actually occurred while driving. I am concerned about safely transporting my family while waiting indefinitely for the required repair.”

“My 2020 Hyundai Palisade experienced repeated instances of the engine cooling fan continuing to operate after the vehicle was completely shut off. In one instance, the fan ran for about 90 minutes after shutdown. After the vehicle was driven again, it ran for approximately another 45 minutes after shutdown. On a subsequent occurrence, the fan continued running until it discharged the battery enough that the vehicle would not start. Southtowne Hyundai in Newnan, Georgia subsequently diagnosed the cause as an internal PCB block failure and replaced the engine-room PCB block pursuant to Hyundai Technical Service Bulletin 26-EE-007H, which addresses battery drain caused by continuous cooling-fan operation after the vehicle is turned off. The dealer installed PCB block part number 91959-S8000-FFF. The failure was intermittent and did not occur every time the vehicle was shut off. My concern is that the defect could unexpectedly discharge the battery while the vehicle is parked, leaving it unable to restart. I am filing this complaint so NHTSA has a record of the failure and can determine whether similar failures are occurring in other Hyundai Palisades.”

“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…”
