All doors on the vehicle lock when transmission is put into gear and all doors lock several seconds after door is shut with engine off. The automatic door locks can not be deactivated by myself or by the dealer. I find this both a safety issue and a inconvenience. As a commercial truck driver driven millions of miles I have both witnessed and have directly been involved with trying to get people extracted from wrecks. Due to locked doors in several cases this has not been possible without breaking a side glass and physically unlocking the door from inside of the vehicle. In one accident two people were unconscious after a crash with the engine running and a fire under the hood, the doors were locked. In another, a person was having an epileptic seizure after a crash and again doors were locks. In the last example a man died after driving into a canal, rescuers were unable to break the glass in time to save the driver. I should have the ability to decide whether to have the doors automatically lock; not the manufacturer. The 2013 and older GMC trucks the automatic door locks can be deactivated but 2014 and newer GM refused to release the program to the dealers or public so I have no option but to drive with locked doors. I am asking to have GM release the program to achieve disabling the automatic door locks.
