I have had my new RHO for 3 weeks now and I have 425 miles on it currently. Today I got the dreaded check engine light, so when I got home I read the codes and they read P0420 and misfires on banks 4,5,6. I read earlier from a post this could be a software glitch, a melted or damaged catalitic convert etc.......I'm concerned and frustrated but others are apparently experiencing the same issues. I could not find the earlier post so I made a new one. If anyone has any new updates pertaining to a resolution I would appreciate the input! The truck starts and idles fine but it has hardly any power. Dealer said they have no idea for a fix at this time.
