What owners wrote
The vehicle was in PARK and the IGN was in the ON/RUN position and the air conditioning was on. There was no one in the driver's seat but there was an occupant sitting buckled in the front passenger seat. The passenger heard a sound (possibly the ICE turning on) and he felt the vehicle move forward about five inches. He became worried about his safety and pressed the IGN button in order to turn the vehicle off. It could have pushed itself into other cars in the parking lot or pedestrians.
The contact owns a 2025 Toyota Grand Highlander. The contact stated that while driving 70 MPH, the air conditioner failed to operate. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the condenser had failed and needed to be replaced. The dealer informed the contact that the front grille had large open apertures and no protective screen between the grille or the heat exchangers. The vehicle was repaired.
