'21 Ridgeline Black Edition
Steve - Here it is 2 days after your post, and the same happened to me today (3/12/22) driving back to Rochester from Minneapolis. I am contacting Tom Kadlec Honda as well. I have a 2021 Ridgeline with only 8500 miles. Pulled off the highway onto a frontage road - flashing CEL came on and I limped to the nearest parking lot. Turned off the engine - waited a minute -restarted and it ran fine the rest of the way home.I see from the NHTSA complaint database that someone from Rochester MN filed a complaint. I am in Rochester and have been trying to work with Tom Kadlec Honda. Normally I have had great luck with them but I got a little pushback when I tried to tell them that Honda needs to be directly involved. It might help if there are two of us with the same issue at the same dealer!
Seems like this is a software related issue that needs immediate attention.
So glad to see you in my neck of the woods.
