Camshaft Position Actuator Valve Solenoid Bolt Replacement – TechLink

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.

what was the symptom of this issue? Wouldn't the warranty on this NEW model cover this?

 

[BCBlazer]

We had no symptoms, they just did the work while we had it in for the hitch install and it was under warranty, we paid nothing.

Sounds fishy if you had no symptoms or check engine light. The dealership may have opened up the engine a bit to replace some solenoid bolts with new of the same solenoid bolts as a way to fish for billable hours from the manufacturer. At least you trust your dealership to do good work, based on the fitment issues they encountered with the hitch installation.

There is a TSB for the camshaft actuator oil control valve (ocv) center bolt a few other ones.

That is a lot of TSB items. None of them are warranty work? Seems that bolt issue could be a problem sooner than later.

They should all be warranty work at this stage of our manufacturers warranty coverage, if your TB has the problem described in the TSB.

Well mine does not have issues but why wait till it becomes one.
