First incident on I5 around exit 186 9 car was cruise control was on. Speed was set at 65. Car was accelerating from 60 to 65 but all of a sudden it slams on the brakes when no car was in front from 60ish to 45. Almost caused the car in the back to hit us. Multiple incident of cruise control on and while automatic lane change it would hit the breaks mid lane change when no other car is present ( especially when the interstate is curving). Going i5 north express lane. Cruise control on there was dotted lines for left exit. Car would was pushed heavily by lane keep to the left. But the intent was to continue on i5 N. The push was a lot stronger than normal. Almost crashed into meridian
