had the same problem---check for prior posts on same subject
It usually a condition where the clutch (f1) has gotten too hot.
I also at one point had it occur very shortly after driving (not a heat issue)...so who knows, but it is typically an indication that the cambio has overheated from too much stop and go.
road runner may be an unknown special option. my car sure has given me a lot of unwanted little treats. blame this on engrs. not paying attn. and not country specific
