I called GM and the Lady told me that there 5 recalls on this truck of which 4 were taken care of. there still remains one left undone. I purchased this truck from a private owner. the one remaining is the seat belt wire issue. A new warning has appeared on the dash, saying service trailer brake system. This a non stop warning while driving the truck. Very distracting and dangerous. I looked on you tube to see if anyone has this problem. yes there are some. One incident stated that to resolve this issue, someone needed to check the trailer receptacle plugin for corrosion, or broken wires. IF all is good there check the other four connectors under the truck on the frame. Finally if these are all good, then check the fuse box under the hood for the fuse for this braking system. The representative that I talked to from GM said to take the vehicle to a local Dealer for analysis to see where the problem is in the trailer braking system. Dealer labor rates are high. The representative stated that there is a payment assistance program available through GM if a Dealer takes care of the situation. Is this true? I need this truck every day for work. Please address this issue . Thank You, [XXX] My email [XXX] . ph# [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
