2026 Hyundai Palisade Powertrain & Transmission Problems

I have the video BUT I AM UNSURE how to upload or share Incident Description: The vehicle is experiencing intermittent, complete engine stalls while in motion at highway speeds. The failure has occurred four times. Initial Symptom: The issue first manifested as "stuttering" and erratic behavior from the Advanced Driver Assistance Systems (ADAS) which I thought it was. Escalation: The vehicle has since progressed to a total loss of power. During these incidents, I was forced to pull over on high-speed corridors (Hwy 46 and Hwy 5) to restart the vehicle. Recurring Pattern: Most recently, after a stall and restart, the vehicle stalled again within a few blocks. I have captured video evidence of the stall occurring immediately after the vehicle was "reset" and put back into motion. Safety Concern: This is a life-threatening defect. The vehicle loses propulsion without warning in high-speed traffic. The manufacturer’s service department (Hyundai) has been unable to identify a diagnostic fault code, citing "No Problem Found," and has only attempted a software/values reset, which has failed to correct the physical stalling.

After 4 days of parking in the garage due to my travel , when came back and tried to start the car it was completely dead. Couldn’t do anything so Hyundai road assistance cane and had to jumpstart the car . Since then dash cam is not working at all and also car is having wierd sound. Hybrid system is just giving me only 15GPM but the car should have around 29 -30 MPG. Car is very new bought in oct 28th 2025. And only gave 225 miles. I am worried if if the battery is working

See attached document for complaint.

I purchased a new 2026 palisade on 8/30/2025. The day after I purchased it I started noticing the car jumping/bucking/hesitating to get up to speed, also it jumps and jolts around different speeds. I brought the car back to the dealership 2 days later for them to look at it. After explaining the problem they drove the car by a tech and also the service manager, with the car being so new. After review of the car, the service person told us verbally that the service manager did feel some hesitation in the car but that the car was so new that it is most likely caused by TAP tables (the car learning how a driver drives). After 30 days of the driving the car, it did not get better, only worse. I brought the car back to the dealership on 9/29 again to have them look at it. They first told me nothing was wrong and that the car just "rode rough" . The service person i was dealing with asked for us to drive in the car together so I could point out what I was feeling when I drove it. While he was driving I could feel the hesitation even in the passenger seat. I pointed it out everytime I felt it, to which he confirmed he felt as well. After the test drive, he allowed me to drive a similar model closest to mine. While I drove that vehicle, I felt that same exact feeling I was feeling in mine. He recommended that I file a formal complaint and that he would send all the information into the warranty department. He also stated during the drive that the new Santa Fe, when they were first released had a similar issue and that they finally release a software update to resolve the issue with the trans and that may also be the case with the new palisade as well. My advice to anyone buying this car, during the test drive make sure you request to take this on the highway and get it in the range of 65-75mph and keep it idle at 70 for a bit and make sure you dont get stuck with the same problem! My previous vehicle had a transmission issue and this is exact same feeling in the Palisade
