We experienced what is referred to as Phantom Braking (Car initiating sudden braking while at highway speeds).  We took it on a 3,000+ mile road trip to visit national parks in the western United States.  Having owned electric vehicles since 2015, we found Tesla's charging network to be reliable and hassle-free to operate.  On a few long stretches of road in Nevada, Wyoming, and Utah we engaged model 3's adaptive cruise control.  Three times during that trip, between July 2nd and July 8th, 2021, the car braked hard, without warning, while traveling at highway speeds.  From what we could determine, shadows cast on the road at the approaching side of gentle hills, with the sun in front of us, may have been interpreted by the car's camera's as an approaching or stationary object on the road.  This was very unnerving and caused us to lose faith in the adaptive cruise control system.  This was both disappointing and a bother since it meant that we were driving a 50 thousand dollar car without cruise control, making driving a more tiresome experience.  This past labor day weekend, 2022, we drove to Las Vegas on the same Tesla model 3 and again activated the adaptive cruise control while driving in Nevada.  We thought that by now the periodic software updates would have fixed the problem.  This time the Phantom Braking occurred more frequently and on seemingly level sections of road.  After about four attempts at using the adaptive cruise control we stopped.  This was, again, disappointing that we were driving a car whose adaptive cruise control failed to perform as it was designed to.  We were disappointed because for what we paid for the car, this feature should be more mature than it is.  Luckily we did not have other cars close behind us at the times the car's computer together with the sensors and / or cameras decided it needed to apply the brakes.","products":[{"type":"Vehicle","productYear":"2021","productMake":"TESLA","productModel":"MODEL 3","manufacturer":"Tesla, Inc."}]}]}
