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.
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.
Xxx - approx 9:00pm - departed copper and sage restaurant enroute to the wigwam. After about 1/2 mile at 30-35mph, I slowed down to make a right turn. After completing the turn I pressed the accelerator to continue and the Palisade had absolutely no power. I pressed the pedal to the floor with no success. I was finally forced to pull over and stop the vehicle and place it in park. After doing so, the Palisade was able to return to operation with the pedal and for fear of another incident we drove home. 2nd incident - 2 Mar 2026 - approx 1200pm. We were traveling west on xxx from [xxx] to [xxx] and began the ascent through the mountains going west towards xxx. After experiencing a steady grade upward approximately 6-7% at speed of 55-60mph, I used the hand shift paddle to downshift one gear to assist in the upward climb. Upon doing so, the Palisade once again died with no power at all. I pushed the accelerator pedal to the floor with no success of power. This incident could have been devastating as we were in the far left lane with many other vehicles behind us. I had no place to pull over to the left so I began to make my way to the right shoulder over 3 lanes very slowly under only previous velocity motion. We narrowly avoided being hit from behind numerous times and finally made it over to the right shoulder. After finally stopping the Palisade, I put the vehicle in park and it returned to operation with the pedal once again. We then carefully pulled out off the shoulder and the Palisade operated normally until we arrived at our destination. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
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 problem appears to be intermittent but recurring, and it has not been properly diagnosed or corrected by the dealership despite repeated opportunities. The vehicle has not been repaired for this condition, and the defect remains unresolved. The condition may be available for inspection upon request, and diagnostic data such as warning messages and onboard fault codes should be present in the vehicle’s system. The failure began with white smoke during cold start and later escalated to engine power limitation and warning lights.
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 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.
