   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…

   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…

   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…

   Was driving 70mph on the highway, all instrument cluster speed gauges go to 0mph and I lose ability to manage speed through cruise control. Was driving blind and had no clue what speed I was going and was extremely worried for my safely. Dealership said my instrument cluster has failed, won’t cover under warranty or as a safety issue. Ridiculous a 80k 6 year old car has a main gauge part fail.

   I recently purchased this vehicle, and shortly after, it began having serious powertrain issues. When I accelerate, the vehicle intermittently loses power and starts shaking violently. It feels like the engine or transmission is slipping or failing. The RPMs surge and drop rapidly, and the vehicle hesitates, jerks, and sometimes briefly slows down before suddenly accelerating again. This creates an unsafe and unpredictable driving condition, especially when merging or…

    The instrument cluster seems to fail more so in the hotter weather. The speedometer, RPMs and gas gauge just stop working altogether. This seems extremely similar to the issues of other Hyundai vehicles that were recalled. The blind spot monitoring turns on and off as it pleases and there is a message that comes up sometimes that say it has been turned off due to electrical failure. The HDMI port in the counsel does not work but half the time so using android auto fails…

    I was driving through town at a low rate of speed (20-30 mph) with 2-3 car lengths between me and the next vehicle. I continued through light to next light. This distance was on an upward incline. After traveling approximately 500 ft, I noticed the traffic slowing in front of me and took my foot off the accelerator to start to slow down. This is when the car suddenly accelerated (instead of slowing down as would be expected when traveling up an incline), picking up speed…
