Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Fall of 2015 the heater and defrost system went out. Only cold air coming through. Entire dash board had to be removed. Vehicle in shop for over 1 week 349 days later in fall 2016 same problem. GM dealer states that the internal lever that closes the heater door broke. This occurs when vehicle is moving or stopped. Repair bill over $1,000. Vehicle still on warranty for 1,500 miles. Concern about long range reliability. One time problem but 2 times in less than a year. Windows fog up and can not see to drive.

The power steering on my 2015 GMC Canyon has failed repeatedly while driving in different road conditions. In one case, I was going straight on a surface street at low speed. However, in another I was cornering through a highway off-ramp at approximately 45 mph. When the power steering fails, there is a warning chime and the power steering and stability control warning lights activate simultaneously. It becomes extremely challenging to steer, and in the case of cornering at speed the vehicle pulls in the opposite direction of the turn [ie, it pulls towards danger]. pulling over and restarting the vehicle has 'solved' the problem each time, albeit temporarily. I took the vehicle to a GM dealer to get fixed, but they could not find any related mechanical issues or GM provided sw patches that would fix the problem. So the GM dealer had me leave without fixing any of the underlying conditions that caused the power steering failure. Needless to say, this is an extremely dangerous and apparently wide-spread issue based on the number of similar complaints I have read.

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.)
