Brake Light On problems of the 2007 GMC Sierra 1500

I lost my brakes while driving. The brake pedal went to floor. Took it to GMC dealer where purchased and was told it was corroded brake lines which had to be replaced. $1300 total cost. No brake warning light ever appeared!!! no other rust/corrosion was visible on truck body except for brake lines. Was told this was an issue of all GMC/chev. Trucks from that time span.

Brake lights stay on. Due to brake lights staying on cruise control is disabled. Vehicle brake opertation is doing the opposite, when in motion stay on and when slowing down or stopped brake lights turn off. Called GMC and informed there is a recall for the same year but for the chevy malibu. Took vehicle in for repair to repair and paid to have the body control module replaced on 02/15/2016, almost 7 months later the issue has returned. Attempted to have dealership that replaced part look at but told there is only a 12,000 mile or 12 month warranty and vehicle has reached over the 12,000 so no longer under warranty. We were also informed the was only a "temporary fix, and the bcm doesn't fix the breaks. " dealership claims the second part that needed to be replaced,which we declined, would have permanently fix the issue. Part had already been purchased at $10 and was going to be charged by dealership $150 for them to provide and install. Called GMC customer service for assistance to correct this safety issue. GMC called to inform us that as a courtesy and the approval by the managers at dealership, will be able to give a $2000 voucher towards a new vehicle or used. Called days later as voucher did not come through via email and informed unfortunately voucher as the vehicle must be under 100,000 mile for trade in. Per GMC customer service at this time unable to resolve correcting the safety issue with body module control and it would be the expense of customer to replace again after its been replaced a little over 7 months ago. Very frustrated as driver of the vehicle is 8 months pregnant and due to break lights not working may get into an accident. We were not informed this would only be a temp fix.

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!!.
