Camshaft actuator oil control valve center bolt binding.
Had this done yesterday while TB was in for a hitch installation that ended up not happening. Service rep called it a recall but I guess it's a service bulletin.
They should all be warranty work at this stage of our manufacturers warranty coverage, if your TB has the problem described in the TSB.at is a lot of TSB items. None of them are warranty work? Seems that bolt issue could be a problem sooner than later.
