The headlights are definitely a failure! Extremely dim... Very stressful to drive at night.

Headlights are not good. For the money you spend on this truck you should have HID or LED headlights.

Recommendation to complete out the Denali Model, tailgate lock should be controlled with the door locks. Just one of the little things that should be included. Sierra Denali should have some of the features found on other luxury brands. Proximity fob for keyless entry and possibly push-button start. Another big item that is missing is the tailgate does not lock when the doors are locked by the fob or by pressing the lock button inside the vehicle.

GM needs to work on color options for there 2500/3500 class trucks. Ford and Ram far exceed GM in this area. Two tone options would be great. The DEF tank needs better engineering for functionality off road and general apperance of the vehicle. GM failed with the DEF tank. The engineers were out to lunch when this tank was put on a 4wd hanging below the frame behind a front wheel. It is a known tactic you place your front wheel on the rock when crossing over it. The tank location and size limits the off road capability of this 4WD.

This truck needs to have a tire pressure monitoring system available. Also, an optional rear seat fold-down, similar to that of the Yukon, should be available on the crew cabs.

GMC 2500 SLE and SLT packages included in the towing package should be power folding large extendable Towing Mirrors! Not sold as an option or regular car mirrors!!!. On Heavy Duty trucks DESIGNED for towing, why would you not include one of the most important safety items in the package! My truck has towing mirrors, but they manually fold in, electric folding is an extra option. At min. at least include auto fold on your SLT packages with towing.
