They should not be selling these trucks to anyone without checking them first.Even if they have to custom tune each truck with issues.
These are not in expensive trucks.
Therefore we should expect more.
I feel your pain.
I have the surging hesitation in low rpm's between 1200-1600 feels like a misfire or timing issue.
My GM dealer ship told me GM knows about the problem but do not know why it is happening there's nothing they can do for me except told me to sit and wait. Thats bs. I called the GM customer service they opened a case for me then they closed the next day because they said GM doesn't have a fix for it and they can't fix it at this time so they would have to close my case? Are you kidding me what kind of customer service is that. I just filed paperwork for my state Lemon law I'm taking GM to arbitration they can buy this truck back I've never had such a crappy running brand-new vehicle shame on GMC. Oh yes and they told me that the vehicle is safe? How can the vehicle be safe when I don't even know what's wrong with it? I also get the fuel pump priming sound when I open up my front door what's going on GM if you can't fix it buy it back. Brand-new truck only 900 miles on it.
