What owners report

The contact owns a 2026 Hyundai Palisade. The contact stated that the vehicle turned off on several occasions after the engine Auto START/STOP system was engaged. The vehicle was restarted and was taken to the dealer; however, the failure could not be duplicated. Additionally, upon starting the vehicle after the vehicle was refueled at a gas station, the check engine and several other unknown warning lights were illuminated, and the vehicle failed to respond while shifted to drive(D). The vehicle was towed to the contact's business. The vehicle was then towed to the dealer; however, the vehicle was not diagnosed because there was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 5,463.

While driving on my 2026 Palisade Calligraphy over last 6 months I lost all throttle/ gas response to engine on 12 separate occasions.The 3rd incident nearly resulted in serious crash in 55mph traffic. Went to dealer next day on 11/15 ref# 41788829 service found no codes, reset system and recommended a flight recorder to help diagnose. Filed with NHTSA on 12/3 after next incident ref # 11702738. Requested flight recorder multiple times with dealer and Hyundai case manager and after multiple visits, diagnostic drives and component replacement on 1/20 and 2/23 the dead throttle continued. On 4/7 I was finally issued recorder and captured 3 incidents of the problem that could not exist within 2 days. Dealer acknowledged problem and says they can not fix without help from Hyundai engineers. Hyundai will not buy back and tell me to go back to dealer for resolution. …

I am reporting a serious safety issue involving my 2025 Hyundai Palisade. The vehicle has repeatedly produced white smoke during cold start and has experienced loss of engine power while driving. Despite multiple repair visits (six times) to an authorized Hyundai dealership, the dealer repeatedly stated that the condition could not be reproduced and no repairs were performed. I provided video evidence of the white smoke and described the symptoms in writing at each visit. Shortly after the most recent service visit(12/22/25), within approximately five days, the vehicle displayed an "Engine Power Limited" warning message and a malfunction indicator light (MIL). When this occurred, the vehicle's power was significantly reduced, making it difficult to maintain speed and creating a potentially dangerous condition, especially during highway driving or merging into traffic. …

While driving normally with the vehicle already in Drive, the vehicle suddenly lost propulsion and displayed a message instructing me to shift to Park or Neutral. I attempted to select both Park and Neutral, but the vehicle would not respond to the shift controls. I ultimately turned the vehicle off and restarted it, after which it operated normally. The vehicle was taken to an authorized Hyundai dealer. No stored fault codes were found, and the dealer has been unable to reproduce the event during road testing and GDS flight recording. The underlying cause remains unidentified. I am concerned that recurrence in moving traffic or while crossing an intersection could create a crash risk.

I was waiting at a stop light when the light turned green. I accelerated and the truck sputtered and cut off. The truck started to sound off with alarms and give a warning on the dash for me to put it in S or N. When doing such and attempting to restart the vechicle it continued to cut off and sound off with alerts. This happened a out 9 times in a row. I was sitting on a busy 6 lane roadway where vechicles go well above the speed limit. I have 4 children under the age of 7 including a 6mo old who were very scared. This is DANGEROUS and I am reading on Hyundai owners forums that this issue is not uncommon at all and Hyundai is well aware of the issue. We could have easily been seriously hurt or killed! I just purchased the vechicle and have only 2,3xx miles on it. It's a 2023 Hyundai Palasade Calligraphy AWD white exterior. …

While driving at slow speed I took my foot off the gas and applied pressure to the brake pedal. The brakes did not work properly; the brakes engaged and disengaged multiple times and the car continued to lurch forward almost resulting in a collision. This is a critical failure of the braking system and is extremely unsafe. In this scenario, I could have hit the car in front of me. Had I been approaching an intersection, I could have been in a severe collision. I brought the car to the dealership and they could not replicate the issue. They inspected the vehicle and did not provide any information on what could have caused the issue. No component was identified as the cause of the problem. No warning lamps were on prior to or after the incident. During the incident, I was not looking at my dashboard; I was trying to not hit the vehicle in front of me. …

Since purchasing the vehicle brand new in Oct 2021, all recommended services have been executed on time. (records to prove it can be provided if required) Aug 25, 2025. Mileage = 78,247. Full preventative maintenance including GDI Fuel Service and Oil change Nov 21, 2025. Mileage = 85,421. I am on a 2 hour commute home and the engine is stalling at every stop. Needs to be re-started each time. Pinging noise when accelerating. The car is brought into Parkway Hyundai in Wilmington, NC. Oil was below dipstick. This lack of oil causes the engine to misfire. I asked why the "low oil" light doesn't appear. I am told that he didn't know but the light only goes on when its completely out of oil. That doesn't seem safe at all. …

purchased a vehicle that has experienced ongoing mechanical and safety-related defects, including excessive oil consumption, seat belt malfunctions, and unresolved injector recall issues. Despite multiple repair attempts by the dealership, the problems continue to persist and have not been permanently corrected. These defects substantially affect the vehicle's safety, reliability, value, and everyday use. The dealership and manufacturer represented the vehicle as reliable and safe; however, the repeated failures and unresolved recalls suggest otherwise. I believe it is misleading to continue selling or servicing vehicles with known defects that cannot be properly repaired. I have also learned that certain model years are no longer sold due to widespread malfunctioning issues that are costly for consumers to repair, yet I was not informed of these concerns at the time of purchase. …
