RDX Error Messages
 

My 2018 RDX recently displayed 2 error messages - Transmission System Problem and Blind Spot System Problem.,
Took it to my local Dealer (CAMCO), they checked and reset and told me there was no problem. 10 minutes after leaving the dealership and on the highway doing 90 KPH + the messages reappeared! CAMCO is 50 KM away and they don't seem to be able to deal with the issue. Don't want to return to Dealer if they can't fix it.
Has anyone else seen similar? Is this a problem ACURA needs to deal with?
