Brake Hoses, Lines/piping, And Fittings problems of the 2006 GMC Sierra 1500

Even though my truck has always been garage kept and only has 30 thousand miles on it, my braking system went out while driving because my metal brake lines are rusted .

I took our truck in for servicing at the o'neill GMC dealership in warminster, PA and was told that all of our brake lines needed to be replaced due to rusting. We purchased our vehicle new from o'neill and have continued to have it serviced there. The truck is treated with great respect and only has 40,000 miles on it. I contacted GMC due to the defective materials of the vehicle they sold us and they claim that this is normal. I now am strapped with a bill for $2700. 00 to replace all four defective, rusting brake lines their website says customer satisfaction guaranteed. I believe GMC should contribute $1700 towards the bill. I note that there are over ten pages of complaints on the internet regarding corrosion problems. Please hold GMC accountable. This vehicle was purchased in good faith and they should admit responsibility for their inferior brake line materials. I am disappointed with GMC's excuses and nonsense. I told them they should pay $1700 out of the money they banked from the expired, extended warranty we purchased. This is a GMC issue; not a jane kearns issue. Again, please hold them responsible for selling a defective truck. Thank you, jane kearns 215-834-7181.

Brake line failure, front left. Steel line had rusted next to a plastic clip that secured a wiring harness to the brake line. Brake fluid was spraying onto the side of the engine. Noticed the leak after returning home; had failed in stop-and-go traffic.

I own a 2006 GMC Sierra 1500 pick-up with less than 75,000 miles on January 23, 2017 I lost my braking capability due to the brake lines being completely corroded/rusted through causing the lost of brake fluid. Luckily I lost my brakes in a parking lot and not on a busy main street or highway with the possibility of having an accident and seriously hurting myself or someone else. From what I have read gm has known about this problem for sometime and says it is not a safety concern. From first hand experience I believe this is a major safety concern.

Pulling out of driveway and brakes gave out. . Stepped on the brakes and truck did not stop. A rusty brake line was leaking. It it had a split in it. Do to rust anand corrosion. This same thing has happened to my father's 03 silverado a few years back. Why has this been an issue with no recall. I had a kia spectra for 15 years and never had problems with rusty brake lines leaking. . . It's a truck they should be built to last. . Smh not happy. .

Right front brake line ruptured when applying brakes in a parking lot. Brake fluid started to leak out from the line that crosses from the driver's side to the passenger's side of the vehicle. It appears the rupture was due to corrosion of the original lines.

Corroded brake lines. No incident as of yet. Serious safety concern because of the quality of the brake lines. Could lead to brake system failure resulting in uncontrollable vehicle. Will need to be replaced/remediated at significant expense.

Brake lines rusting out needed immediate replacement in virginia where little salt is used.

My 2006 GMC has only 29,000 miles on it. I bought the truck in October 2009 with 16,000 miles. I keep the truck clean inside and out, top to bottom including under the vehicle. People comment to me all the time on how nice the truck looks. Brake line let go in yard. Pedal went to the floor, no brakes had to hit reverse then neutral and the emergency brake. I had just returned home from going up town. Thank god it happened where it did. I have been driving 40 years and only replaced one brake line in a 11 year old Ford truck and that was just a section near a bend. This truck needs to have all the lines replaced. I just replaced all the transmission lines 4 months ago for $800. 00. Same thing, all rusted. I lived in massachusetts my whole life and I do my best to keep the salt off the truck. Last time I ever seen rust issues this bad was in the 1970s when cars would start rusting out after 3 years because of the reused steel that came from overseas.

I wake up early on Sunday, on 11/16/15 and took a company truck a 2006 GMC Sierra 1500, to bring some cargo. On my way back home on 836 west expressway, I took my exit and when press the brake pedal to reduce speed, the pedal went to the floor of the car and the brake action was minimum to nothing. Another vehicle was stop at the traffic light, and to avoid the obvious impact to the stopped car, I pumped the brakes several times and applied the parking brakes at approx. 30 mph. Seeing no way to avoid the collision, I pull the car to the side of the road and hit a concrete water drain, resulting in abruptly sopping of my car and my knee hit the lower dashboard. The guy of the other car went out and ask me, are you "drunk" "are you ok" I called a flatbed and bring my truck to my work place and then notice that a brake line was broke and most of the brake fluid spilled all over the front of the chassis, under the radiator. The brake line was incredible rusted, reason for the brake down, I had cars with a lot more years with no problem with brake lines. When I inspect the other brake lines deeply, noticed that an excessive corrosion was in all of them. GMC should do something about this, safety issue, is no reason for a 2006, only 8 years vehicle, present that level of corrosion on brake lines. "coke can thickness apparently" . Somebody will die or seriously injure, or will kill somebody, pedestrian or driver because the sudden brake failure in a case like this. I will bring the vehicle to a garage to replace the broken line and probably all of them. . Its ridiculous, and very dangerous that this things happens in a vehicle that age. I really appreciate to bring this case to the proper attention of the manufacturer in order to avoid more incidents like mine. I consider myself very lucky,. Could not be writing this if this happens to me at a high speed. Thanks. ,.

Approaching red light signal applied brakes. Driver rear brake line ruptured due to rust through. Was able to safely stop vehicle as my speed was only about 20 mph. If this were at highway speeds it would have been extremely dangerous. Fyi there is also extensive frame and body surface rust that the manufacturer refused to help with. This vehicle is mostly parked outside in the mid atlantic regions. Gets very little use so low mileage. The rust is from a manufacturing issue not an environmental issue .

Since roughly June of 2014 complete vehicle shakes violently when brakes are applied. I have had it looked at and have been told that it is the brake lines abs and needs replacement. I am a single father of two boys struggling financially and cannot afford new brake lines. I also have a current situation where the rear bumper is completely rotted through and as a result cannot pass state vehicle inspection I have searched for 2 months and cannot find a used rear bumper and manufacturer cost is $450-$500 which I cannot afford at the moment. I have always had a GMC pickup and am very dissatisfied with my present situation as I have only put 25,000 miles on the vehicle since purchased.

I was driving down a hill and applied the brakes and the brake pedal went all the way to the floor. There was no resistance to the brake pedal at all. The brakes functioned properly when I stopped at a stop sign, then when I was going down the hill the brake line broke.

While slowing to make a turn I applied the brakes and had a sudden and complete loss of brakes. Had I not been on a suburban road or in traffic or a high speed highway the situation could have been catastrophic and resulted in a crash. I was near my repairing garage and managed to get the vehicle there by using the emergency brake and low speed. It was less than a mile. I had this repaired at a cost of $849. 27. Just yesterday (6-30-2014) I was parked on a hill and as I released the parking brake my foot suddenly went to the floor and I experienced a second loss of brakes due to failure of the remaining two brake lines. I was on a hill and had only a tiny amount of braking power. The vehicle is at the garage and the cost of this repair has yet to be determined. They will replace the remaining two brake lines. I recently had to replace the transmission cooling lines which ruptured and are located in a nearby location on the vehicle. All are exposed and un-shielded. The manufacturer advertises that the vehicle is "professional grade" and "heavy duty" but I find both these claims to be great exaggerations. These situations have scared me and I desire to acquire a different vehicle as soon as I am able. Unfortunately, this will not be soon. I will have to drive with the fear that another potentially catastrophic problem could develop at any moment. Fortunately, neither of these incidents were panic stops.

Hydraulic brake line rust out results in loss of stopping ability. The "blow out" occurred while the vehicle was stopped (I was very lucky!). Upon inspection, several of the hydraulic lines were rusted badly. I felt that I had to replace them all (with stainless steel lines) to prevent another failure which could have dire consequences. The cost of the replacement stainless steel hydraulic lines was over $300. I performed the replacement of these lines myself. It cost me an additional $180 to get the complete abs braking system bled out.
