Vehicle has adaptive cruise control to reduce speed by braking when other vehicles may be struck. unfortunately this models brakes are often applied when the radar detects other traffic which will not be a factor; i.e. a second car has left the interstate and is slowing to stop before turning on a secondary road. my vehicle will brake regardless whether a third vehicle is cruising a highway speed behind me. similarly if i am moving with traffic in the center lane and overtaking an 18 wheeler on the right moving 10+ miles slower. my vehicle will brake to match the speed of the truck regardless of the speed or proximity of vehicles behind me. the manufacturer advises this is my vehicles design and no fix or modification is needed. this has been an issue reported to multiple dealers since about 5000 miles. hi how
After setting the cruise control at 70mph it will accelerate 5mph
The car has collision avoidance breaking but i noticed a time when a collision was not going to occur and the breaks were applied without me actually applying the breaks. i could have been rearended if there was a car behind be because there was no need to break. a car was a few hundred feet in front of me turning right at an intersection in my lane, and then i was traveling about 35mph and going straight through the intersection. the car had completed its turn in front of me and as i approached where the car was, it applied the breaks as if the car was still there but it had previously cleared the lane by 5 seconds or so. there was no need to break and caused me to be to potentially be harmed by that breaking action. the car slowed down to about 15mph before allowing me to continue.
