2025 Hyundai Palisade: engine stalls while driving

Filed Sep 28, 2026 · Driver assistance · OH

On August 10, 2026, at approximately 12,302 miles, I took the vehicle to an authorized Hyundai dealer after it stalled multiple times, including once while accelerating. I also reported sluggishness/loss of power. The dealer was unable to duplicate the problem. The vehicle subsequently stalled two additional times. In September 2026, while driving at highway speed with cruise control engaged, the vehicle suddenly and aggressively decelerated/braked as though it detected an obstacle ahead, although no vehicle or obstacle was present. A similar event occurred the following day. Unexpected braking, loss of power, or stalling at highway speed creates a serious collision risk. I have also experienced a forward-collision warning when no vehicle was in front of me and intermittent jerking/hesitation. I returned the vehicle to the Hyundai dealer on September 22, 2026, at approximately 14,548 miles. The dealer performed diagnostic scans and approximately 42 miles of road testing. No relevant DTCs were found, the problems could not be reproduced, and no repair was performed. The dealer documented the result as No Trouble Found. There were no consistent warning lamps or messages before the stalling or unexpected deceleration. The cause remains unresolved despite multiple dealer visits.

At 16 thousand plus my car was at a stop light and stop/stalled/shut down what ever you want to call it. The auto stop was on but this was not the problem. I physically had to restart my car in traffic. The next time I experience this was at 20 thousand plus. We were in the hospital parking garage and the car again stop/stalled/shut down and I physically had to restart it again. This time I was driving with the auto stop off. I have experience this again at 21 thousand plus. Again I was at a stop light. The auto stop was off. The car stall/stop/completely shut down again. Car had to be restarted while again in traffic. Hyundai had been notified of the stall/stops. This was the last time I was dealing with this problem and took it into Happy Hyundai in Libertyville Illinois. They had it for a week. They did run test, but the car was not giving any codes. Happy Hyundai did not run it over the weekend for on my bluelink I get notification. On Monday my husband called and told them to drive it because this is when we are experiencing the problem. Happy Hyundai drove it once. Tech was not able to replicate it. My husband also took Happy Hyundai to let it run. They let the car run. This is what happen when we were in the hospital parking lot. We were sitting. The safety of the person driving the car is at risk for a accident. There have been reports on they Hyundai facebook web sites of the car stalling while driving at speed. I carry my handicapped daughter in my car. This stall/stop becomes a worry some problem, not knowing when it is going to shut off again. This has caused me much anxiety. I don't even want to drive my car. This is a accident waiting to happen. Along with many law suite's. No dash board cluster lights were on when the car stall/stop. Car has been inspected by Happy Hyundai and is now going back per Hyundai Coporate wanting a tech to pull codes.

Vehicle stalls while at red lights stop signs or in parking lot. No lights come on prior to it stalling it just stalls throws itself into park and stalls. Very scary situation.

Occasionally, the car's RPMs fluctuate wildly, and the engine stalls; the surges in RPM lead to sudden, abrupt acceleration, which poses a safety risk to me and my family. The dealership has been unable to resolve the problem.

Unknown. Twice while trying to accelerate onto highway on ramp, the car did not go faster immediately as expected. It didn’t pick up speed. I’m trying to go from 35 to 60 and there’s a delay from the time I step on gas until the car actually go faster. It didn’t stall or shut off. If someone was behind me, I fear i would have been rear ended. Dealership said diagnostic test was fine and unable to reproduce. They reset computer and said it must be my driving. Car had ~310 miles.
