NHTSA Complaint #11607533 — 2021 HONDA RIDGELINE

What happened? While driving in the right lane on a two lane highway, I slowed slightly when approaching a vehicle ahead of me. I then started to move into the left lane to pass when the engine stopped (as confirmed by the tachometer quickly dropping to 0 (zero) rpms). In response, I started feathering the throttle and moved back into the right lane where the engine restarted on its own. I then continued my trip without further incident. This happened with approximately 60,000 miles on the truck which was purchased new by me. I did have a similar incident when the truck was much newer but didn't pay much attention as I was still learning Honda's ADAS and wasn't sure if 'pilot error' came into play. And to clarify, the only safety that was in use this time was Lane Keeping Assist but it wasn't active as I was actively signaling my lane change. Questions under your General Guidelines: While the engine stopped unexpectedly, I don't believe it was an engine fault simply due to the number of miles I've driven the truck with no similar problem. While my wife and I weren't at risk since traffic was light at the time with no one behind us, I can see a safety issue in heavier traffic, especially if the engine doesn't restart as soon as it did. The truck has not been inspected by Honda. I did file a complaint with American Honda (case #14787271) and they simply suggested a visit to my local Honda service department. But due to the very limited occurrence of this issue, I can't see how their service department can be of any help. During the incident occurrence, there were no warning lights, messages or otherwise hints of an impending problem.
