NHTSA Complaint #11468050 — 2021 HYUNDAI PALISADE

Environment: Passing a single car on a two lane deserted highway. Daytime, sunny, no rain. Issue: The vehicle's emergency braking system activated (brakes were automatically activated along with the emergency braking cue in the instrument cluster) when the vehicle was returning into the right lane, almost causing a collision between the two vehicles at 85 mph. This occurred a second time 15 minutes later under the same conditions. The car was taken to the dealership for inspection and repair. The dealership test drove the vehicle and could not replicate the issue. Hyundai Engineering noted that since they were not able to replicate the issue and there were no active codes there is nothing wrong with the vehicle. If the radar is functioning properly, there must be an issue with the software of the vehicle.
