I have a new 2015 Touring with about 7000 miles on it. We enjoy the car, no problems other than the strange performance of the Adaptive Cruise Control system. I have searched this forum and searched the web for this situation and find very limited information. Here is the situation: When I have the ACC set for a cruising speed, and I come upon a slower vehicle, the car slows down to maintain the correct distance. That's fine. But if I move into another empty lane the ACC system senses this and accelerates at a very high rate, like it is mashing the accelerator to the floor. The RPM's shoot up to 4000 RPM or more. I don't drive like this myself, I would accelerate at a more reasonable rate. Is this a known problem with this system? Has Honda acknowledge the problem? Is there a fix for this? It would seem that the acceleration rate is controlled by the computer, so it should be possible to change this acceleration rate.
