2018 GMC Canyon

Vehicle has less than 25,000 miles. Over the last 3 days, after vehicle is put in park and turned off, the key will not always rotate back to the 'off' position, and can not be removed from the ignition. This has happened at least 6 times over the last 3 days. Managed to remove key by turning vehicle back on and driving back and forth a few inches, then trying again. Took multiple tries on some occasions. With less than 25,000 miles, nothing should be worn out... Safety concerns:The possibility that the key will completely fail to be removable, meaning that if the vehicle must be left unattended, it must be left unlocked and in a condition that it could be started and stolen or driven by a curious child. The possibility that see-sawing back and forth in a parking spot could lead to an accident. The possibility that the vehicle will have to be towed. The possibility of being stranded outside- all my keys are on one ring, if I can't get them out of the ignition, how would I open the door to the house? The problem has not yet been reproduced or confirmed by a dealer or independent service station. I will be calling to schedule an appointment. The vehicle or component has not been inspected as of yet. No warning lamps, messages, or other symptoms happened prior to the first incident. When I returned home and had an opportunity, I did an internet search and discovered that the problem is a known issue, and has been reported by others.
