Brake Light On Problems of GMC Sierra 1500 - part 2

2007 GMC sierra crew (new body style) while stopped at a stop sign I nearly had a vehicle rear end me. I had my brakes depressed and noticed my brake lights were not light up. I then pressed a little harder on the pedal and then my lights came on. This new brake light where if you step as hard as you want on the brake and then let off a micro inch and it goes off. So I got home and did some searching and found that this type of problem is occurring quite a lot with this truck my thought on this is that any time the t brake pedal is even depressed just a little bit the lights should go on. I did also find it strange that the brake lights do not work with the ignition off. First vehicle I can recollect ever set up that way.

I was pulled over by my local police department for defective brake lamps 3 times. I have gone to my local chevy dealerships and they replace the switches 4 times. I then got pulled over again so I brought it to lemay Buick and GMC in kenosha WI. They replaced the brake lamp switch 2 times. When you push on the peddle and let up just a hair the brake light go inop. This is a major concern for me because I could get rear ended at anytime with no brake lights. I hooked up a light on my dash to let me know when they are or are not working at highway speeds the lights do not work 95% of the time going 70mph and slowing down to 55mph the lights don't even blink. I tried calling GMC and they said there is not a problem with the lights on these vehicles.

The brake lights turn off if you press the brake and then slightly depress the pedal, although the brakes are still applied the brake lights are not on. I first noticed it while backing out of a driveway at night, and I did not think it was a safety concern until I saw my wife stop from 45 mph and the brake lights flashed and then turned off until she came to a complete stop. I took the truck to the dealership they thought there was a problem with the truck, and replaced the brake light switch. The problem did not go away. The same defect is on every truck on the car lot. The dealership wrote on my invoice that the owner presumes that when the brake pedal is pressed the brake lights should be on. Duh!!.

I have a 2004 GMC Sierra 1500 z71 pick up and the abs and check brake lights keep coming on and off. After taken in to shop (dealer) they could not find any fault codes finally late 2008 I had it looked at by a local shop and they believe it is a bad card . Some times it wont go off for months and other times it is none stop.

My abs system has failed the motor runs consistently by the pump under the drivers side door, I pulled the wire connection harness to silence it and now I have a constant yellow abs and red brake light on the dash panel. The dealership did the front sensor recall but still have the existing problem. This happened 3 years after I bought it but my warranty was up after 1 1/2 years because of my distance from my employer ate up the warranty.

The anti-lock brake system light illuminated. The vehicle was taken tot he dealer who diagnosed that the abs pump motor had seized and caused the abs to fail.
