2026 Hyundai Palisade: hesitation when accelerating

Filed Oct 12, 2026 · Engine, Fuel system · CO

The engine misfires and runs very rough when stopped in drive after highway driving, and the vehicle hesitates and struggles to accelerate from a stop. At about 3,000 miles, Phil Long, Colorado Springs diagnosed a failing cylinder 6 fuel injector and replaced it on 22 April 2025. The problem continues after that repair. The condition repeats in the same way. After 15 minutes to 1 hour of interstate driving, I exit the highway. When I stop at the first traffic light on the off ramp, the engine begins idling very rough, and the tachometer shows about 500 RPM. When I shift to park, the idle smooths out. When I shift back to drive, it becomes very rough again. Pulling away from the light is difficult because the vehicle hesitates and does not accelerate normally. This has happened three times since the repair, most recently on [XXX] at about 5,800 miles. The check engine light did not come on. Conditions: 80 F, clear weather. [XXX] exit [XXX]. This is a safety concern because the vehicle may not accelerate when I pull into an intersection or merge into traffic. Other 2026 Palisade owners have reported similar misfires and hesitation, and Hyundai issued TSB 26-01-068H (Service Campaign 9D6) for engine misfires on 2026 Palisade 3.5L vehicles. I have asked Hyundai to confirm whether this campaign has been performed on my vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While traveling along a high-speed highway, our 2026 Palisade unexpectedly suffered a severe loss of acceleration. Despite fully depressing the accelerator pedal, the vehicle struggled to exceed approximately 20 miles per hour. This alarming malfunction placed us in a precarious and potentially dangerous situation, as the drastic reduction in speed exposed us to the risk of being rear-ended by faster-moving traffic. On a separate occasion, the vehicle again exhibited troubling behavior, failing to respond appropriately while merging onto the highway. This hesitation significantly compromised our ability to safely enter the flow of traffic and could have easily resulted in a collision. Disturbingly, in both incidents, the vehicle provided no warning indicators or alerts on the dashboard, leaving us without any guidance or explanation for these critical failures.

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
