When on a cold start , and backing low speed ...the brakes go to floor and barely stop vehicle...was told by gm that the brakes are going through check, and it is normal for brakes to go to floor and not stop vehicle. *tr
No brakes going forward or backwards but only for a few seconds, always have full pedal and the harder you push/force they slowly bring vehicle to stop. my wife and i have almost hit pedestrian's and vehicles. *tr
When at a stop and when i go to take off car rolls backward. this car has a automatic trans, but act like a stick trans, i bought this car new off lot. and first brakes keep locking up like something is in it. but if i roll backward it disengages . i've taken it to the dealer a couple of times due to this issue and they also heard it but never could find anything. i really like this car but it falling apart from day one.. i keep it serviced like i am suppose to.
