The headlights on this truck are so dim that at night it is difficult to see the road you are driving on. GMC needs to address the problem with a headlight replacement or major improvement.

The transmission does not down shift when climbing a small hill in normal traffic at normal speeds. I constantly have to use the manual transmission to make the truck downshift or I have to press on the grass in order to bring the RPM up a little higher using more fuel than required. This in itself is dangerous since I am in then middle of traffic. When I purchased the truck none of the recall were on carafe nor did the dealer inform me that this vehicle type and model has already had several recalls affecting its performance and safety. There is also something wrong with the defrost system whether its on heat or cool. There is a rattling noise that can be heard over the fan noise when the vehicle air conditioner is switch to the defrost mode. I am truly disappointed and very concerned for my safety. GM should have pulled this vehicle off the market!

(3rd) - occurrence of the following same problem....the heater and defroster systems in my new 2015 GMC Canyon produce only cold air, regardless of the settings. This creates a fog film on the inside of the windshield making the Canyon inoperable due to lack of visibility. The GMC dealer has already replaced several "heater/defroster", but the new system continues to fail. The lack of heat problem occurs at all times (I.e. manual key start, remote start, cold engine start, warm engine start, etc.)
