I have a 2013 FFH hybrid that I tow behind my motorhome. About half the time, when I start the car after towing, I get a transmission error code. However this error code goes away after driving the car once or twice. I have the car in for it's (final) warrantee service, and the dealer says that there are no stored error codes in the transmission. Anyone else experience this problem, and any thoughts on what is going on? The dealer suggest that I just ignore the warnings.
