2026 Hyundai Palisade: check engine light

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)

We lease a 2026 Palisade with only 4k miles. Several weeks ago I was going through a toll plaza, car would not accelerate after slowing down, as if it was in neutral. All of a sudden it kicked into gear and car lunged forward. 10 min later at a traffic light car failed to accelerate after a complete stop. Press the accelerator sluggish response, then kicked back into gear. Very Scary. I pulled over and notified the dealer. Then set an appoint. Dealer did a diagnostic, found no issues, could not replicate problem on test drive . Everything was fine a few weeks. My son took the car. Had the same exact issue with vehicle not accelerating. Then kicked into gear really hard and vibrating. This was scary for him because he was in a parking lot. Luckily there was no accident as a result. However, this time an error code (check engine light) came on and the Hyundai app showed a DTC CODE- P001600 (powertrain / engine). Car was immediately taken to dealer on May 28th 2026. It is now Jun 11th. Still no time frame for fix. The THINK it a software issue and Hyundai is still "working" on a solution.

I picked up my vehicle from the dealership after it being there for almost 2 weeks for multiple DTC codes, a dash cam component replacement, and recall updates. On the way home, my check engine light flashed on and off multiple times while driving at highway speeds (although no codes were recorded in my Hyundai app diagnostics). When I exited the highway, I came to a stop sign on the off ramp and waited till cross traffic cleared. I went to accelerate into traffic, but my car would barely move. This happened 4 more times in the short drive to my home. This could pose a serious safety risk if I'm unable to accelerate to merge into traffic and get stuck in cross traffic.

I have been continuously receiving check engine notifications that show the engine cylinders misfiring. This seems to only happen at highway speeds which could cause a safety hazard should the driver need to accelerate for merging/passing/etc. I have brought this issue into the dealership once so far and they said they couldn't do anything since they were unable to replicate the issue while driving it. From what I've seen online, many other owners of this vehicle are having similar problems with the same responses from their local dealerships.
