Upper radiator hose connection to radiator is faulty causing leak of coolant. Yes it is available for inspection upon request.  Truck began to run cooling fan at full speed in the middle of winter with no warnings of high heat or low coolant. After two weeks, check engine light finally cut on to indicate low coolant flow. Coolant reservoir was subsequently checked and found to be completely empty. It is apparent this reservoir had been extremely low / empty for at least two weeks with no warnings. Without proper warning and leaking coolant, truck could have overheated. Should this had happened in dead of summer, truck could have very well overheated with no warning.  The problem was investigated and confirmed by dealer as leaking coolant at the connection of the upper radiator hose to the radiator. Was quoted $983 to replace the hose.   No warning lights appeared until issue had been ongoing for over two weeks.  A quick search of "GMC Canyon Upper Radiator Hose" will reveal many identical occurrences of this issue. This is a safety hazard / design flaw that GM is not acknowledging and is putting the burden on the vehicle owners for their own issue.

Coolant Leaking at 22K miles, smell of coolant, check engine light on and off 2X's. Coolant evidence on driveway and in engine cabin. Known condition for GM Model. No parts available for replacement. No recall for issue.

There are widespread reports of the O ring seals on the radiator and heater hoses failing and causing coolant leaks. These leaks are significant enough to render the vehicle inoperable and with no cabin heating or cooling. This could lead to life-threatening situations in adverse weather conditions. It could also create dangerous roadside failure situation in heavy traffic, particularly on interstate highways. Dealers are aware of the issue and are currently repairing vehicles under warranty. However some dealers are telling owners that the cooling system is not part of the engine and drivetrain, and therefor is not covered under the original factory warranty if the vehicle has exceeded the initial bumper to bumper warranty limits. Dealers are also telling owners that parts are on backorder due to high demand, and that repair wait times could take weeks. The vehicle is unsafe to operate with a known coolant leak.
