I will never reach that space in time or miles before this unreliable defect laiden poorly designed piece of shody merchandise kills me or someone else. The service dept wants me to authorize take down of transmission and dissemble the unit and said needed to notify GM. Also they mentioned 66,790. Is this a form or a charge?. I called them back only to get a recording. I said (my exact words) I authorize GM/ dealer to repair this vehicle now at their cost and deliver it asap. Come Monday this will be 4 days no truck. This will force me to use very harsh civil complaints for these interruptions. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
