I used to love this vehicle, now I can't wait to move on. The child lock for the doors is located on the armrest and is very easy to turn off without knowing it. I found out when my 2 year-old granddaughter managed to get the back door open while I was driving on highway 400! I went all the way to the vice-president of design at GM and was told this was a safety feature in case you need to exit the vehicle quickly even though the owner's manual CLEARLY says the doors cannot be opened or unlocked when the vehicle is moving. I pointed out that if the child lock is on, the door can't be opened. They stuck by their guns and now I am stuck with a vehicle I don't feel safe driving my grandchildren in. GM is the only vehicle I have owned and I am sorry to say I will never own another one.
