2025 Hyundai Palisade Fuel system Problems

“I smell gasoline through the AC vent at every stop when I drive the car locally at low speed (under 50 mph) after the car has been parked overnight. The smell eventually goes away after driving a while, but it comes back the next day when the car has been parked overnight. I feel like the smell is worse as the fuel tank gets lower. I took the car to the dealership and they were not able to identify the problem.”

“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.”

“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. …”

“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. …”

“Upon returning home on 7/20/2025, I smelled a strong odor of gasoline. I looked under the car and saw that gas was leaking from a small hole on the (R) rear side of the tank. The hole was an approximately 1/16 . Due to danger of flammable fuel vapor and leaking gas I parked away from the house and put a temporary plug to stop the leak. I was shocked to find that the fuel tank was unshielded and made of thin walled plastic. There no warning indicators given prior to this incident. The vehicle has 12383 miles on it. Cause of the leak is unknown, possibly a poor mold casting of the tank.”
