What owners say
Auto stop start does not work properly in this vehicle after repeated fixes by Honda and dealership. Vehicle sometimes does not restart after stop start engaged at stop causing a stall like event. Auto stop start tries to start vehicle after stop but vehicle either stalls/fails to restart or is extremely slow to restart. Vehicle has been repaired, new starter, new battery, new relays less than one year ago and vehicle is now experiencing the same issues. Owner (me) is now disabling feature every time vehicle is started to prevent system from engaging.
