We ran it with the broken pump just long enough for my wife and daughter to get safely off the highway and for me to drive it less than 1/2 mile to the dealer while investigating to see what it was actually doing -- this was about the least we could have done.
When the oil pump was repaired I discussed the possibility of engine damage with the service manager. It was his opinion after having his technician open the engine and inspect it, that replacing the oil pump would be all that it needed. I trusted his professional opinion and had the pump replaced. Now, less than 1 week later, there's tapping in the top... go figure!
It's out of warranty because the service start date is 11/11 (it's a 2012). Even though it still has miles to go, the warranty expired 11/16 -- 5 years/100k miles on the "power train" (which apparently is what covers the engine). The oil pump disintegrated 12/16.
Your frustration is completely understandable, gunner76. If you are interested, I'd like to reach out to your dealership to help get you scheduled for a new service appointment and assist throughout the diagnostic/repair process.
I know that service costs were a concern with your previous visit. While I can't guarantee any specific outcome in regards to cost assistance for repair fees, I can definitely see what options may be available!
If this is something I can assist you with, please send me a private message with your VIN, contact information, vehicle mileage and dealership name.
