What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Low beam headlights failed during driving at night nearly causing a serious accident. Many lives could be affected because of this well known design issue not being addressed by GMC. There is a GMC recall for this same problem, but my vehicle isn't included. GMC needs to re-evaluate this issue and include more vehicles. They know the problem exists and should make efforts to include all affected vehicles.

Exhaust manifold bolts broken, causing uncatalyzed exhaust emissions under hood and resulting in increased co (carbon monoxide) levels entering the cabin through the HVAC system during engine operation at slow speeds or while parked.
My vehicle's headlights have started to turn off for no reason, sometimes while driving and sometimes while waiting at a traffic light. They come on then without an intervention.
