general problems of the 2003 GMC Sierra 1500

My truck hadn't been driven for a couple of weeks, but there was no indication of anything amiss the last time I drove it. The truck is parked at the top of a approx. 40ft. Long driveway that is moderately steep. I started the truck and slowly began backing down the driveway and the brake pedal went all the way to the floor. It flew down the driveway, going between a parked car and another steep hill, winding up in my neighbors front yard, where I managed to abruptly turn it and bring it to a stop before going thru his living room. Frequently, there are as many as 6to8 kids playing there, but being a bad weather day(cold),, luckily, there was nobody there. The possibilities of a terrible disaster are frightening. As it stands, the only 'disasters' are the ruts in my neighbors yard, a destroyed recycling container and my bank account,-to a tune of just over 1700$. My mechanic says he has done over a half dozen of these repairs lately. To my way of thinking, gm is seriously negligent regarding this problem, which I have discovered is fairly common. Are they waiting to see how many horrific events occur before addressing this? at the very least, they should give reimbursement to those of us that have gone thru this. And where is NHTSA's action on this issue???.

The abs activates at low speed braking under dry road conditions without the tires locking up. The brake pedal vibrates as if I were on ice with the tires locked up. Braking effect is reduced under these conditions. This happens randomly and when it does I cannot be sure if I can stop in time before hitting the vehicle or object in front of me.

82k miles, original owner, well maintained and garaged. Had to stop at a red light and the pedal went to the floor as I went into the intersection. Luckily no other cars were ahead of me and nobody was hurt. Dic lights came on and brakes have not worked since limping my vehicle back home.

Pedal went to the floor on exit ramp. No warning. Truck went off road to avoid cars stopped at ramp end.

Leak.

I was pulling up to a busy intersection I went to step on the brakes they were gone. Lucky I was able to jump the curb and come to a stop, before hitting any one . Upon inspection the brakes lines were rusted through!!!!!!! note!!! I had my truck in for a oil change and 27 point inspection the day before. At the dealer.

My wife was parking and brake pedal went to floor.

Backing up toward 60 ft dropoff to unload debris. When I hit the brakes the pedal went to the floor. Stopped with e-brake or I would have been down that 60 ft drop. Checked under truck and fluid was running out a break in the line from rusting through in the middle of the line,not at a fitting. Was very lucky that I stopped in time. That would have left a mark!.

The contact owns a 2003 GMC Sierra 1500. The contact stated that while stopped, the brake pedal was abnormally depressed to the floorboard. The contact was able to safely drive the vehicle home and park. Upon examining the vehicle, the contact noticed that the brakes lines were fractured and corroded. The vehicle was not taken to have the failure diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 80,000.

My 2003 GMC Sierra 1500 sle has corroded brake, transmission and fuel lines. A certified mechanic stated that they all need replaced or breakage and leakage will occur without warning causing break, transmission or fuel delivery or fire damages. Please help with this problem ASAP. 00.

2003 GMC half ton sierra truck. 3 time since 2003 that I've had to take it in for clunking noise felt thru steering wheel. Lubed a couple times then replaced the intermediate steering shaft. Still no guarantees that it won't happen again. Also very hard to steer when braking and brakes don't respond well when applied quickly. The first time the intermediate steering shaft needed attention the truck only had 15,000 miles on it. The second time was 30,000 miles and the last time was 45,000 miles and occurred in March 2010.

Starting at <5k miles the vehicle power train clunked when shifting from 2nd to 3rd gear. Now at 70k miles it clunks when shifting between all gears except final drive. The dealership replaced the output shaft on the tranny, then the u-joints, and modified the electrical shift patern. It still clunks. Power steering intermittently locks up at slow speed turns, especially when braking. Light bulbs burn out almost every three months. Had to pay ($486. 00) for replacing the intake manifold gasket when vehicle had little over 40k miles. Brakes fade and the pedal almost goes to the floor, again intermittent. I have almost caused several accidents due to the steering and brake issues. GMC issued a letter stating "this is a normal occurance and will not cause damage. " well, it's getting worse in sound and clunking harder during shifting.
