A couple of weeks ago got this message saying see a dealer but the next time we drove the RDX it was off. The message returned last week and while it was on I took it to the dealer. Diagnosis was a bad sensor which they had to order. I waited over the weekend before having it fixed and the error message would come and go. Sensor replaced Monday and the error has not returned.

While we were at the dealer we reported that we had the Brake light come on and braking action took place when we were on a 4 lane divided highway with no vehicles in front of us or beside the road. We were near an overpass so I guess that was what triggered it. Anyway their response was NTF(No Trouble Found).
