NHTSA Complaint #11429814 — 2021 ACURA RDX

Driving at night in rain on interstate 81N in southern Virginia. I pressed accelerator all the way to pass and the car downshifted and then lost power. The engine light was flashing. I did not have enough power to maintain adequate highway speed while in the midst of a passing maneuver. While car was decelerating (with foot on accel pedal with no apparent response) I activated hazard lights and made my way across traffic to the shoulder. 70mph speed limit. I dropped to 50mph or so rather quickly amid traffic that put me and the traffic around me in a dangerous situation. Once stopped on shoulder (again in a dangerous situation that I'd prefer to avoid), i turned ignition off for 10 seconds and then restarted car. Situation seems to have cleared up; no engine light flashing and full? power. It did not happen again when I pressed accelerator to floor to recreate situation. This vehicle has 3800 miles on it.
