“My vehicle is a 2007 H3 Hummer and was not manufactured with rear, child safety locks for the doors. The dealership, as well as the manufacturer assistance number can not provide a retro fit to correct the issue and only provided an option to purchase a new vehicle to correct the issue. I have a 2 yr child that continues to open the door while the vehicle is in operation.”
