“I see there was a recall from GM #17399 for the 2015 dual fuel tank sending unit problem. This is only for the 6.0 l gas engine. I have the duramax 6.6l engine in mine. I had the same problem with mine. The sending unit did not turn off the transfer pump and overfilled the front tank causing fuel to pour out all over the road. I caught it before the drive line caused any damage. I had it towed to the dealer and while we moved it to pull it up on the tow truck it was pushing fuel out of the filler neck of the front tank. …”

“I was traveling on a busy roadway at 40 MPH when fuel filter warning light came on suddenly and vehicle lost all power - including the loss of power steering and power braking. Thankfully I had not yet entered the highway and was able to slow vehicle down but with great difficulty and not injure anyone around and that day was not towing a load. Vehicle would not restart. I had it towed to nearest dealership who then informed me that the bosch cp4 fuel pump had exploded sending metal shrapnel throughout the entire engines fuel system. …”
