2015 GMC CANYON ALL TERRAIN STALLS OUT

[kazerz]

I LOVE MY TRUCK... But for about the past month it's been a little puzzling. Engine has decided to stall. First just started to idle rough & act as if would die but never did. Now on several occasions it has stalled. No eng light, battery light, no light s came on. It was as if the computer wasn't aware the engine has stalled. No problems with restart. Also started losing power & losing gas mileage. Took to dealer but aside from doing some updates they said there were no engine error codes.

 

Any ideas???

Bad gas is my first guess. Try Water remover in the tank..

 

I had to completely drain my tank in my old 07 Colorado because of this same type of issue.

 

Also did you try disconnecting the battery and letting the system reset.
