The brakes failed while driving on a city street causing my vehicle to nearly strike a number of children at a crosswalk. After examination by a mechanic, it was determined that the brake line had corroded and burst under pressure. I have received no notice of this potential failure from gmc even though it has been investigated by the federal safety agency. Shouldn't the manufacturer have an obligation to repair this potentially lethal problem? At a minimum I feel that gmc and/or the federal safety agency have a moral obligation to notify owners of affected vehicles that they are driving a potentially deadly vehicle.

Total brake failure, no brakes. Steel brake line rusted through on frame rail near gas tank causing fluid container to empty completely. No advanced warning lamp or indication of failure. To replace the line, the fuel tank must be removed. Dealer charge $800.00 and up.

I had a panic stop while driving my SUV, and the brake pedal went to the floor, offering almost no braking ability. This caused me to sharply swerve around the car in front of me, drive through a red light at a busy intersection into oncoming traffic, and find a safe place to land. I had my 11 year old daughter and 9 year old son with me, this could have been deadly.

Car pulled in front of me, had to apply maximum braking effort. Pedal went to the floor and the truck gradually slowed. Further attempts to drive and brake were futile.

I was driving our 2003 gmc yukon xl home and the brakes went the floor, let me tell you this is very scary especially with such a large vehicle. Luckily I was a block away and made it home pumping the brakes. The brake lines broke just above the rear axle. Both lines come out of a connector and they were very severely rusty, it is tough to see unless you remove the spare tire. If you look at the same brake lines that run across the rear axle, they look fine. Don't let that fool you, they may be very rusty up farther where you can't see. Doesn't make sense to me, but we also lost our brakes with no warning in our 2002 gmc yukon. This has happened with 2/2 gmc from 2002 and 2003 there must be many others and accidents from this happening, its a very fast loss of brake fluid with no warning. Gm has to do something about this if they want our business again.

On 1/4/14 my wife was sitting in the drive thru lane and when she went to put the truck in drive the pedal went all the way to the floor. Had it towed and found a rusted and leaking brake line. Second incident on 2/1/14 while driving and approaching a red light I applied the brakes and the pedal went all the way to the floor. I pumped the brakes enough to where I got the vehicle stopped after going through the intersection without being hit. I got it off the road and had it towed once again. Another brake line had burst and fluid leaked out. The mechanic states that all of the brakes lines are rusted, some more than others so I am having all of the lines replaced. Some type of recall needs to be done as I am reading on line of other owners having problems with premature rusting.two lines leaking within one month is unacceptable.

I started my truck. I applied the brakes and shifted into drive. I began to roll forward, then applied my brakes prior to exiting my driveway. The brake pedal went to the floor, the brake service light came on and the truck continued forward. I had to pump the brakes to come to a stop. I pulled the truck over and observed brake fluid all over the street. I crawled under the truck and saw that the brake line was rusted and that it burst somewhere in the middle of the truck on the driver's side.

Brake lines under drivers seat are completely rusted through. Vehicle is garage kept and seems to be experiencing excessive rust on brake lines. While driving vehicle brake pedal went to the floor almost causing me to have an accident. My family and I own and have owned numerous gm products and we're very disappointed with this safety hazard not being addressed by gm. Maybe it's time to shop elsewhere...
