GREAT NEWS!!! Just picked up our 2015 GMC Denali truck today! Took 1 month for dealer to repair because GM did not know which pump to replace failed Bosch pump.....
100% covered under drive train warranty!!! Dealer says he they repair these all the time!
Lessons learned: GM Customer Care is an outsourced, 3rd party vendor....they just refer back to the dealer (which in our case, dealer #1 didn't want to cover repair)
Don't give up, just because dealer said repair wasn't covered!
Thanks to everyone for input and support! We are lucky we were NOT towing trailer at time of pump failure!
