From the day i took delivery of my 2020 rdx advance in august, i've been completely crazy about it. now, however, i'm feeling sad and disillusioned, but more importantly, i don't feel 100% safe driving it. recently, after spending a few weeks in georgia, we were driving back home to northern virginia on i-85n in north carolina. it was and had been raining steadily the entire trip. there was moderate/heavy traffic moving at speeds between 60-75/80 mph. somewhere just south of charlotte, the car suddenly started slowing down, even though i was pressing the accelerator! it was barely moving in the middle of traffic. the check engine light was blinking and the engine was rattling and sputtering. i immediately turned on the hazards and started crossing the two far right lanes to get over to the narrow shoulder. terrifying. fortunately, we were only about a 1/4 mile from an exit. we slowly made it on the shoulder to one of gas stations there. after checking the support section in the app and calling a tech at my home dealership, i shut the car off and let it sit for about 15 minutes. it started and we were able to finish the trip without further incident. we made it home safely, but the remaining six hours of the trip were mentally excruciating. we drove as slowly as safely possible in the right lane. i couldn't get it out of my head that it could happen again at any moment. and, i can't say it hasn't crossed my mind that i won't be able to get over that extended feeling of uncertainty while driving it. at least, not for now. i took it to the dealer on 11/25/19. they said they could not duplicate the issue, and that there were neither error nor fault codes stored. i had been hoping they would give me some explanation and reassurance that everything is fine. i wanted to feel 100% that the car is still safe to drive, but i'm not feeling that now.
