Recently my 2002 chevrolet avalanche has begun to shut off while driving which causes the vehicle to lose power. Another important safety issue, the brakes began to press all the way to the floor while braking. On august 3, 2011 while my son was driving the vehicle approaching a stop light, he pressed the brakes which went to the floor and rear ended vehicle in front that was making a turn. The front bumper is now damaged ( t-boned) and the air bags did not deploy. I'm not very pleased that I never received any notices about the braking system. I can't afford to make monthly payments and still have to pay costly maintenance fees. I can not afford to jeopardize my life and my family, especially my granddaughter. Something has to be done about these safety issues: braking, cutting off while driving and no deployed air bags.

The dash light stays on constantly showing the security light, gas light and battery light flashing. When you shut the truck off it still shows the yellow security light and it never goes off and if you leave it sitting for 1 or 2 days without driving it makes the battery go dead.
