Those were probably already en route to the dealer before the strike affected parts. I don't know about Fed Ex but UPS will not cross picket lines so not likely anything will come unless already in the shippers hands.
I got the other 2 recalls done tuesday and they said there are no parts available for the particulate matter sensor so they could not do that one. then thursday when I ran my vin thru the recall website, the sensor recall had gone away..curious. I guess the dealer cleared all 3 but only the relay and the dipstick show on the work order.
