2023 Hyundai Palisade electrical system problems

“My car has been giving me issues for over 6 months. The staff at Hyundai have no idea what is going on. I bought my car from Hyundai and have only gotten service from Hyundai. On my dashboard you will see several lights blinking. The seatbelt signs in the back light up when no one is in the seat. The lights on the dashboard are very dim. The blinkers do not work sometimes. Some days I cannot automatic start or open the back cab. All of this is random and happens whenever with no warning.”

“I am reporting a serious safety issue involving a 2023 Hyundai Palisade with approximately 26,000 miles. While the vehicle is being driven, the ESC warning light illuminates and the vehicle can unexpectedly come to a stop, shift into Park, and shut down. The vehicle must then be restarted before it can be driven again. This condition has occurred while the vehicle is in operation and creates a significant safety concern because the vehicle can unexpectedly stop in the roadway. If this occurs in traffic or at highway speeds, there is a risk of a rear-end collision or other crash. The vehicle has been presented to/communicated about with an authorized Hyundai dealership, ALM Hyundai Florence in Florence, South Carolina, but the issue has not been resolved. I am also reporting the issue directly to Hyundai Motor America. I am requesting that NHTSA document and investigate this condition to determine whether other 2023 Hyundai Palisade vehicles have experienced similar ESC-related shutdown, stopping, or unintended shifting-to-Park events and whether a safety defect may exist.”

“The seat belts in passenger seat don’t work either too long or won’t extend Forward collision warning is always on AC Does not work properly I’ve called the Hyundai redmccombs dealership multiple times and even Took the car and they Said the part was ready then they say it wasn’t The seat belts is a huge safety concern since I do have children and other Riders. It’s unacceptable to be promised the car fixed then delayed . I spent time at the dealership, gas and not Being able to pick up my child due to this .”

“On June 27, 2026 I started the vehicle and every warning light came on and the gauge cluster started cycling through system failure warnings for most every component/system on the vehicle. The vehicle was barely drivable, with no power steering, no backup camera, no AC, inoperable gauges, no safety/driver aids, and hard shifting. It was taken to Bentley Hyundai in Huntsville the same day. The vehicle was diagnosed with a CANBUS failure and after weeks of troubleshooting they said it was a bad engine wiring harness. The new harness was installed under our extended factory warranty this week. I was informed today, August 29, 2026, that there are still electrical issues with the vehicle. I am concerned about the safety of this vehicle now due to the length of time it has been at the dealership, 60+ days, and continuing issues even after replacement of a major component of the electrical system.”

“On August 4, 2026, our 2023 Hyundai Palisade was brought in for a routine oil change and rear tint recall. The driver's power seat height adjustment mechanism worked perfectly upon drop-off. When the car was picked up, the height adjustment function was no longer operable. The service department inspected the car and admitted that a factory wire bundle beneath the track was physically snapped/severed. To make matters worse, we discovered upon pickup that the vehicle's computer system had been completely factory reset. This was done without our knowledge or consent. When questioned about this, the service manager was entirely unable to provide any valid justification for why an oil change/rear window tint service would require a total system reset. This strongly indicates that service person experienced an electrical short or attempted deep electronic troubleshooting while the vehicle was in their possession, further implicating their shop in this damage. The service manager insists that their team did not cause the damage. However, they were unable to return the seat to the position it was in when dropped off. The primary driver of this vehicle is under 5 feet…”

“Our Hyundai has a powertrain problem that is intermittent and random, and manifests itself in a couple of ways: 1) It drops out of gear while you are driving; there is no forward propulsion at all; the engine will rev when you press the gas, but no forward movement at all. You have to coast to a stop (or panic stop if the traffic allows), put it in reverse, drive backwards, then the transmission will “chunk” back into gear, then you can put it back in drive and continue forward again. This is life-threatening on a busy road or highway. Traffic has to flow around you like water around a rock in a stream while you try to use what’s left of your forward momentum to pull to the side of the road. Absolutely terrifying!!! The dash has also gone completely blank during some of these episodes. Nothing changes the situation: pressing “D”, shifting the paddles, nothing gets the vehicle back in gear. We have video taped these events twice, and provided those videos to our Hyundai Service Center, and to the Hyundai National Consumer Affairs team. They claim that they can’t reproduce it on demand, so they have done NOTHING. We are scared to drive the car. 2) As you start…”
