Stopped at the gas pump and filled up. When I went to leave all dash lights were lit up and car wouldn’t move. Brakes were locked. I tried restarting and restarting. Brakes would lock up when I tried to move, either direction. I finally gases it enough that it screeched the tires to move it from in front of the gas pump.
Since purchasing the vehicle on February 4, 2026 this has happened twice, where I press the brake pedal to try to stop the vehicle and the engine accelerates and it's hard to keep vehicle stopped. When this happened for the first time I was leaving my subdivision and try to stop at a stop sign and vehicle accelerated while I was trying to stop. It took me by surprise, so I pressed the park gear to stop the vehicle. Then it happened again yesterday 2/22/2026. I called the dealer today 2/23/2026 to report the issue, they won't have a loaner until 3/06/2026. I did informed them, that if this happened again before then, I was taking the vehicle directly to them, as I'm no taking the chance to have an accident while waiting for a loaner and have the vehicle checked.
Driving around 30mph pressing brakes to slow down and brakes felt softer than normal. Noticed when around 7 mph car continues to not come to full stop but continued to move. This happened 3 times during the same drive. Once on my street I attempted to slow down to turn into my driveway. Car reduced to 5mph but jersey and accelerated. Had to slam brakes to stop. Was not detected by dash cam which is programed to record driving events. Bought a sante fe car in sept 2026. Had same incident. Swapped it for 2026 Palisade calligraphy, had same incident. Swapped for this one. . Dealership says could not duplicate. Obvious it is not an isolated problem. What can be done?.
