So the other day i was going for a little drive. when warming up the drivers info center tells me "LOW OIL PRESSURE" "TURN OFF ENGINE"
and i look into it at the dealer and theres a bulliten saying there is a concern about faulty relieve valve inside the oil pump that means no oil to the top of the motor, thank my lucky stars that i was at home and did'nt drive or run to long without oil.G.M has not come out with a revised part# for this fix so i bought a standard volume /high pressure pump from MELLING and all is well.
Don't have the T.S.B. # here at home. if you can't find i'll post it up when i get to the shop.
