Purchased a 2020 Palisade in March of 2024 with 76k miles on it. Asked the dealership we bought it from to look at the transmission after a week of owning the car, they said it was fine. I took it to Hallmark Hyundai dealership on 9/26/24 and they would not look at it until i had the transmission fluid flushed this was at 88430 miles. It was barely making it up a hill, we had the gas pedal to the floor and it was pulling back like it was going to stall. I scheduled to have the transmission fluid flushed at a local certified mechanic and he found tons of metal shaving and chunks throughout the fluid this was done at 89368 miles. I took it to Wilson County Hyundai after this was done and they said I needed a full transmission replacement this was done at 89643. They replaced the transmission, and on my way home from picking the car up there was metal grinding sounds coming from the transmission. I called Wilson County back and they asked me to bring it back, it was back on their lot less than 24 hours later. The transmission that was sent from the manufacture was a faulty transmission. The replaced the new transmission, and the sound stopped this was done at 89730 miles. After a couple thousand miles the metal grinding came back, along with the hard shifting, gear skipping, excessive vibration between gears, going up in RPMs but not shifting. I took it Jim Johnson Hyundai and they reset the Transmission adaptive, this is not fix the problem this was done at 96497. It back in the dealership now at Wilson county with the mileage of 99000 and their service manager told me they have 5 of them on their lot right now needing new transmissions. The car has less than 100k miles on it.
