Three problems related to ignition have been reported for the 2000 Chevrolet Blazer. The most recently reported issues are listed below.
Go to vehicle, try to start, "security" lamp begins to flash. No start issue. Have to wait for 10 minutes and try again, about 50% of the time is starts, other 50% you have to wait another 10 minutes and try again. . . . Gm passlock system issue. Is it the ignition, the bcm, the ecm. . . . ?.
I own a 2000 chevy Blazer and when it rains the brakes go out the vehicle will not stop the pedal won't go to the floor and it when you try to push the breaks it makes a funny clicking kind of noise and the pedal just hops not letting you break. Then when you take off after you stopped (by the emergency break)the back end slides sideways like the front breaks are locked up. I almost killed myself and my kids because I couldn't stop! that is extremely dangerous! it only happens when it rains or go through water. Others with the same kind of vehicle said the had that problem as well.
I have multiple complaints, the gas gauge on my vehicle stop working and I ran out of gas in the middle of the street when I realized problem 2 the rear brake lights and hazard lights do not work. The other problem is the vehicle stalls, and when it finally take off, the car jerks and the driver seat moves/slides back from the hinges which caused me to not be able to reach my breaks and run into a curb. Also the driver side door sticks and is difficult to open. Lastly the wheel baring and ball joints have gone bad twice and the car has less then 75000 miles on it. I called gm customer service department and explained all of my concerns and was told they we not aware of any nationwide problem and there was nothing they could do except fix the hazard light malfunction. I researched on the net and found many many people complaining of the same concerns I have.
