2025 HYUNDAI PALISADE Engine Problems

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. This issue poses a serious safety risk because sudden loss of engine power can increase the risk of collision. The...

The vehicle has roughly 8500 miles on it in the first year. We have experienced multiple engine misfires due to bad ignition coils on cylinders 3 & 4. The first incident was in July 2025, and the second was in November 2025. The first incident was on the freeway, going 75mph, and the second was on a city road, going 35mph. The first incident, I brought the vehicle to the dealership, and they replaced the coil, cleaned the cylinder, and covered everything under warranty. The dealership told me this is common and Hyundai will not replace the remaining coils until they misfire, even though the dealership knows the coils do not perform well in colder weather. I called corporate regarding this issue, and they confirmed that they will not replace the remaining coils, although a mechanic at a dealership they work with has already confirmed they regularly misfire. The Hyundai...

The engine issue first started as a small knock and hesitation during acceleration, which has now progressed into full misfiring and loss of performance. Diagnostic documents indicate internal mechanical failure. Hyundai has failed to timely fix the issue, and the vehicle remains unsafe to drive. I was issued a loaner vehicle but told not to drive it out of town. This left me and my family without a safe and reliable form of transportation. I am requesting a full investigation and buyback of this vehicle due to repeated failure, poor service response, and continued risk to driver safety.

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.

Unknown. I was exiting the freeway onto off ramp, was slowing down to break for a line of cars at a red light and the car shut off and stopped before i came to a complete stop on my own. All lights on dashboard lit up. The dash said the engine is off and to push the P (park) and restart engine. I had to do this quickly twice before car actually started, as traffic started to move. Luckily, a collision in the front and back was avoided but this was extremely unsafe and unexpected. Now I’m scared to drive this car. After car started, the engine and oil lights came on then went off within a few seconds. Appointment scheduled for dealership diagnostic testing.

Unknown. In a span of 15 minutes, I encountered 3 events in traffic where accidents could've occurred. I was in the middle turning lane, completely stopped. I tried to accelerate and start left turn when the car shut down, all lights on dashboard lit up. There's an alert saying push P (park) and restart engine. It took 2 or 3 times of trying to get the car to start. Once started the engine and oil lights came on. They went off soon after. Luckily, the car stopped before the turn started or there may have been an accident. I continue my drive down the street, come to an intersection where I slowly brake, the front passenger tire hit a pothole and the car slid into intersection (my foot still on the brake) instead of coming to a compete stop before the intersection. Again, accident avoided only because the oncoming traffic...
