On 10/26/25 at approximately 3:40pm while on a freeway (traveling approximately 65mph) with no traffic or cars in close proximity for the automatic brakes to be engaged, the 2025 ev equinox slammed its brakes on its own without driver braking. This caused whiplash to be experienced by two of the three passengers and it felt like we were rear ended but no cars were around. This is very dangerous. Had there been car behind me this would have caused serious accident.
