Not sure about the specific equipment, but I have an update on my door locks. I had a conversation with the service manager of the dealership at which I purchased my 7 year / 100K gold plus extended warranty. That talk went quite well. Once the actuators were diagnosed as in-operable by CarToys, the dealership replaced them. We are back on track with excellent service... recovery.
As for the head gasket concerns, check your year and model here...

...seems they have fixed the oil leak issue in newer models.
