This has happened twice now. 1st occurs on the DC beltway in VA HOV lanes, outer loop just past Tysons Corner while going 70+ MPH in the lane with no vehicles around the collision warning system and break automatically alerted , sensor indicated and dash board flashed BREAK. It resolved on its own. This was in august on a hot sunny day, no rain, no fog. The second occurrence just happened two weeks ago. It was sunny, 55-65 degrees, 35-49 PMH approx 3 vehicles back while turning south from rote 27 in mount airy maryland onto Penn shop road, the vehicle did the same thing. Indicated I was going to crash, applied the breaks automatically and almost caused an accident with a vehicle traveling behind me. First time I thought was a fluke- second time- no. Will be sending to dealer. Vehicle has less than 25k. 2020, Calvary blue, 4x4, shortened, crew max.
