NHTSA Complaint #11619610 — 2019 HONDA PILOT

3 episodes of unexpected and sudden braking for no reason. Twice on Sept 13 when ACC was in use and set at 70 mph the car hard-braked and dropped to 40-42mph rapidly, then it stopped braking and I was able to use the accelerator again- the braking lasted perhaps 10-15 seconds. The third episode was on Oct. 13 and the ACC was not on. I was driving manually at 55 mph and again the car suddenly braked and dropped to the same 40-42 range- maybe 5-10 seconds before the accelerator started to work again. There was no reason for the barking, no warning notices on the dashboard. Thank goodness there was no-one close behind me on any of these occasions, because the drop in speed was fast and hard.
