I refuse to own a GM product. Bottom of the quality and poor electronics bin in my opinion.
The dealership brought in the truck I wanted to buy. 2015 CCLB lariat with the ultimate package. SHe was gorgeous. It had 86 miles from getting driven from another dealer and I took it for a drive with the salesman and I was ready to buy it. On the way back to the dealership (20 mile loop) the check engine light came on and it went into some sort of limp mode. DEF level was fine and it had a full tank of diesel.
Dealer is looking at getting in another truck.
Dealer said tech hooked up IDS and it had a bunch of U codes and some emissions codes.
I won't lie at all I am now very nervous even though I know it's a machine and things happen. I'm waiting on a call from the dealership on what they find and when they can have another truck.
