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.

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.

As I approached the traffic light from a parking lot, at slow speeds ie 5mph, I hit a patch of uneven ground where the concrete was uneven. The brakes stuttered and lurched. I pumped the brakes without much success and came within inches of hitting the car ahead of me. This has happened multiple times. Another time, I was approaching an intersection again at approximately 30 mph. The brakes stuttered so hard that I barely stopped before entering the path of the oncoming traffic. On a later separate time, traveling at approximately 35 mph, we were fully in the crosswalk when the car finally stopped. These were just the scariest of times, not inclusive of all occurrences. The trouble began within the first few months of purchasing the car in 2023 and still happens. I reported this to the dealership on several occasions. They claim it is normal for the vehicle but it is a danger to the occupants in the car and the nearby pedestrians.

Two simultaenous problems happened: 1) loud clunking/thudding during low-speed turn. 2) Clunking/knocking/rattling noise from suspensions when going through uneven grounds. This both things happened before 20,000 miles. Had AWD coupling and rear differential unit replaced under warranty regarding problem 1). Had rear shocks replaced under warranty regarding problem 2). Found there has bben TSB issued related to 2), for older models, TSB 25-SS-004H but not for this year of models. Those two exact problems started again at about 40,000 miles. Had vehicle checked at 50,500 miles recently. Regarding problem 1), the dearship found issue with AWD coupling, stating faulty parts, drive shaft seal was 1/8" off and materials are fused. Replaced AWE coupling, and ECU program update. After program update, I do not see the power distribution monitor anymore from my dash. The program update should turned it off for some reason that I do not know. I have no clue that AWD module is working normal as I cannot see the power distribution action anymore. Regarding problem 2), they replaced both rear shocks again. The problem went away for now. This vehicle has been only 50,000 miles and had 4 major issues (2 times of two major identical issues) that alongside with many owners' compaints, and seems highly related to one of Technical Service Bulletin that was previously issued for older models. I would like to request investigation on these services.

I am writing to file a formal complaint XXX regarding a severe safety defect on my 2023 Hyundai Palisade. On XXX, in [XXX] while driving under normal operating conditions, the sunroof glass spontaneously exploded with a loud noise resembling a gunshot. There was no vehicle ahead of me, no overpass overhead, and absolutely no external object or road debris struck the vehicle. The glass shattered violently upward and outward, which is a clear physical indicator of a spontaneous thermal or pressure-induced failure caused by a manufacturing defect, rather than an impact. As you are aware, spontaneous sunroof shattering is a heavily documented issue across 2023 and 2024 Hyundai Palisade models. Numerous identical complaints have been filed with the National Highway Traffic Safety Administration (NHTSA), pointing to a known defect in the tempering or structural stress of the panoramic glass panels. I have attached photos and a video of it still making sounds in the photo, you can also tell it is bubbling upward. This vehicle is well within its 5-year/60,000-mile New Vehicle Limited Warranty period. This failure represents a severe, sudden compromise of passenger safety, and I expect Hyundai to honor its warranty obligations. I demand that Hyundai Motor America authorize a full replacement of the sunroof glass, a thorough cleaning of the headliner/cabin to remove microscopic glass shards, and a complimentary loaner vehicle while the repair is being completed. I look forward to your immediate response and prompt resolution to this safety matter. Sincerely, [XXX] and [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Recall # 26V034000 for my 2023 Hyundai Palisade has not been resolved after 9 months since it was issued. Dealership all say they do not have the parts to remedy this recall. I have made repeated attempts to get this issue resolved and I have contacted the manufacturer for assistance but they have not resolved the issue. I get the run around. The dealership say they do not have the parts the manufactures says that the dealerships should have the parts. I find it totally unacceptable that the dealerships cannot resolve this serious safety issue. It is a critical safety issue that should be resolved.
