So the part that is a malfunction is the rear doors weren’t made with any child lock and of course one of my kids opened the door while i was driving on the highway.I have a 3 and 5 year old and it scared me so bad I had to hurry and pull the hummer over and park and just held my son. I couldn’t even drive after that because of how bad it traumatized me. My mom had to come get and take me and my kids home and drive my hummer back home. Even though we didn’t crash or one of my kids didn’t fall out.it’s still a very serious safety hazard. I reached out to gm to see what my options were and there response was how gm made child locks in 2007 and up and that’s not the truth because mine is a 2007 and it clearly doesn’t have child locks. Then they later proceeded to tell me I should just sell my vehicle. I was so upset because if one of my kids would have fallen out and something happened I would do everything in my power to make sure they were held accountable and file a lawsuit against them. Yes The vehicle is available to inspect. My kids safety was at risk and then me braking and pulling off the highway in panic mode could have caused an accident.it’s been reported to gm and also local dealers. There was no warning just when it happened scared me so bad because my kids are in my back seat. The photos I uploaded are of the transcribed voicemails and I’m willing to also submit the voicemails from gm as well.
