I have a 2013 Accord Touring, and have a problem with the ACC from adjacent lane interference. It's almost as if the unit is calibrated for right-hand drive countries. When in the left lane, traffic in the right lane causes the ACC to slow the car. But when in the right lane, traffic in the left lane is pretty much ignored.

Anyone else experienced this problem?

 

I saw on another forum where an owner had a similar problem.

He touched the round housing that surrounds the sensor for the ACC and it moved before locking into place.

It was apparently angled improperly by being loose. Put some pressure on yours and see if it moves and if so, lock it in. That may be the solution to your problem.
