Consumer Description
Multiple times on highway car “phantom breaks” when there are no obstacles/cars in front of me. I noticed that the car seems to regularly do this at certain places the highway. For example, on one stretch I’ve had it happen multiple times going under a specific bridge when I’m in cruise control. The car seems to think the speed limit has reduced, leading me to believe the car is reading the overpass speed liMit, not the highway, and adjusting. On another highway, after a steep decline there is an incline. At the end of the decline, the car slams on the breaks as if it thinks the incline in the road is an obstacle.
