Automatic Transmission problems of the 2004 Chevrolet Suburban

When the vehicle is placed in the accessory position, the brake does not have to be pushed on to put into gear. I was on the side of the vehicle and turned away and my 2 year old was able to climb into the front seat, put the key into the ignition and turn it to the accessory position and into gear. The vehicle rolled out the drive up on the curb, hit a mail box and since the door was opened -luckily it did not run into the house. I was under the impression that when that there was a law passed that stated you have to push on the brake to put the vehicle into gear. Luckily no one was driving down the road and hit the vehicle with my children in it. I took it to the dealership and they said it was a towing feature, I personally think this is very dangerous considering the fact that this is a common SUV for people with children and it would be very easy to have this vehicle stolen. I took pictures of the vehicle and paid someone to have this fixed, however; I feel this should be a defect in the 2004 chev. Tahoe and should be covered under warranty damage. Thank you for your time and in the future if this is not recalled or fixed - I will not be purchasing another chev. Vehicle and I know several people who will not be also.

Vehicle was able switch gears without applying brakes. As a result, the vehicle rolled down the driveway with a four year old child inside. No impact reported.

I had my 2004 chev Suburban parked in my garage. My 8 years old daughter was in the back seat listening to the radio. I had the gear in park and the key in the accessory position so she could listen to the radio. From the back seat she reached up to turn off the radio and accidently hit the gear shift. The car went into reverse. The drives side rear door was open. When the Suburban rolled out of the garage the rear door caught on the garage door keeping it from rolling into the street, into a pedestrian or into the house accross the street. There were no injuries. I notified gm product alligations department, tim miller, about the incident. He stated that this vehicle could be put into gear without using the break when the key is in the accessory position. They were not willing to look into this as being a safety issue. The owners manual suggests that you use the accessory key positioning to "let you use things like the radio, power windows and the windshield wipers when the engine is off". I think that gm needs to look at installing some type of feature that requires the brake to be engaged to shift the grear out of park even when the key is placed in the accessory position similary to standard no. 102 - transmission shift lever sequence, starter interlock, and transmission braking effect - passenger cars, multipurpose passenger vehicles, trucks, and buses (effective 1-1-68) this standard specifies the requirements for the transmission shift lever sequence, a starter interlock, and for a braking effect of automatic transmissions, to reduce the likelihood of shifting errors, starter engagement with vehicle in drive position, and to provide supplemental braking at speeds below 40 km/h (25 mph). Please advise on how to proceed with installing some type of safety measures in the chev. Surban so a fatal injury does not occur.
