NHTSA Complaint #11607713 — 2018 SUBARU OUTBACK

When traveling on hwy at hwy speeds with cruise control on set for 70 mph and car in front is traveling 60 mph as am I. The road curves the car no longer identifies a car in front of me and accelerates to 70 mph, when the road becomes straight again and I am getting close the system slams on the brakes. When I'm going 70 mph and approach a car going 60 mph the car slows to keep a safe distance. As I change lanes the car begins to accelerate. As I am passing the slower car, if on a curve and the car identifies a car in another lane and slams on the brakes. This has caused road rage from drivers approaching from the rear in the passing lane thinking I'm braking to slow them down for no reason. The Dealership told me to turn my cruise control off on roads nort straight! This has happened since the car was new. This occurred on a recent trip across country on hwy US 40.
