Yup, I've had this on my '08. Hey - maybe it's a free 'Gremlin' I shipped in with the Hugger ???
Same symptoms, same side too....
Anyway, it turned-out to be the small white plastic turn-signal connector under the dash. There's one for each indicator, where the wires come out of the stalk, and they don't have 'locking' tabs on them !!
I removed the dash (a few tiny 3mm-or-so hex bolts) and unplugged it, and found the loose connector. I cleaned them thoroughly, then shrunk a big piece of shrink tubing over them to hold them tight. Fine ever since.
Hope it's that, cos as you say, the 'turn relay' is in the dash CPU ...
