The contact owns a 2001 GMC Sierra 1500. The contact stated that while driving approximately 10 mph, the brake pedal had to be depressed repeatedly in order for the vehicle to come to a stop. The contact mentioned that upon stopping, the vehicle lunged forward. The failure occurred intermittently. The vehicle was taken to an independent mechanic, who replaced both front wheel ABS sensors. The failure recurred and the vehicle had not been repaired. The manufacturer was notified of the failure. The approximate failure mileage was 122,000.

After backing my truck into my driveway, I was reaching into the back seat while pressing on the brake pedal. All of a sudden my foot on the brake pedal went to the floor. Upon investigating I found that I had a hole in my rear driver side brake line. It was completely rusted out. Further investigating showed that all the brake lines are very rusty and in poor condition. I have repaired the ruptured line, but am fearful of another rupture. I believe that GM should be required to replace all the brake lines on this vehicle. Why does GM not use high quality stainless steel brake lines for all vehicles? all vehicle makers should be required to use high quality stainless steel for brake lines and brake components susceptible to rust.

Was about to go shopping for christmas gifts, stepped on brake at top of court and the peddle went to floor. Not just loss of hydros full on brake malfunction, no brakes at all. I live in New York and truck was purchased from Connecticut. Decided to make left turn and missed getting hit by 18 wheeler by inches. I am lucky to be alive to be typing this now, no thanks to GM. No warning lights nothing at all just no brakes. To add emergency brake did not work.

Sudden rupture of brake line due to heavy corrosion. Rupture was evident along a seam in the brake line from the manufacturing process. Rupture greatly reduced the braking capacity. Rendered vehicle unsafe to drive.

  • 69,100 miles
Brake failure due to severely rusted brake line at driver side rear wheel. Rust is severe on all surfaces underneath vehicle. Will require complete replacement of all brake lines and other assorted brake components. ABS was malfunctioning prior to brake line rupture, likely due to corrosion within wheel/hub assembly. This malfunction is known to GMC, and occurs by the ABS erroneously sensing wheel stoppage at low speed, causing the system to activate and inability to stop. This has caused near misses in parking lot situations, thus the ABS has necessarily been disabled until repair (pulling fuse). Not the kind of issues a low mileage truck should be experiencing.

My ABS control module is not functioning properly. ABS is disabled and costs $1000 to replace. This is a safety hazard as the brakes can lock up at any moment or ABS is disabled and may cause brakes to lock up. The ABS light on dashboard is on continuously and the module will need to be replaced or further damage will occur.

Driving less than a half mile from home when I applied the brakes and experienced total failure without warning. Upon inspection brake lines were rusted and one failed. As I was removing to replace all of them due to the rust conditions, several of them were brittle enough to break upon manipulation.

My wife applied brakes to stop at a red light and pedal went to floor with no warning light and with the grace of god it stopped before we were T-boned in busy intersection. Amazing that GM can put stainless steel exhaust which by the way is still on the truck but not the brake lines!!!!!!!

The brake line that runs above the gas tank is leaking. I have no brake pressure. This has been a well documented General Motors problem.

Two things started to happen 1. the truck when coming to a stop of a speed of less then 25 mph started to lose its brakes and feel spongy. This continued until I got it in the shop which was about two days. 2. the truck started to run very rough and the engine light was coming on at the same time as well. After I got it in the shop and they got it up on a lift they found that all of the brake lines and fuel lines were all most rusted through and starting to leak. They had to replace all of the brake lines, fuel lines and since they had the fuel tank down they replaced the fuel pump because they found rust and dirt in the old pump. The shop mechanic said the lines were ready to fail at any moment. The Chevy dealer I bought the truck off of just four months early had just inspected it and had seen the rusted lines and even repaired a piece of one of the fuel lines but left the rest go to fail down the road, they gave me little to no help. This is a huge problem, dangerous as well as very expensive one and needs looked into. Is there any help I can get for this problem??

I was going through an intersection at about 30 mph when my brakes completely failed. I applied my parking brake and swerved onto a nearby lawn just missing a car in front of me. I had my vehicle towed to a mechanic, who told me the brake lines were all rusted through and there was no way they should have been this bad for a vehicle that was well-maintained. I subsequently investigated and found there have been numerous complaints about this problem. Why has nothing been done" my wife, daughter and I could have been killed. Why should GM be allowed to get away with this"

Driving down the road in my 2001 GMC pickup when the line of vehicles in front of me started slowing down, I applied my brakes and the pedal went to the floor. I had to swerve to my left across traffic to avoid rear ending the vehicle in front of me. The momentum of the truck took me through a small parking lot and into a building. I do not have the VIN as this happened about 3 ? years ago but I suspect it is available somewhere.

Moving the truck out of my driveway I experienced a soft brake pedal. Several minutes later total brake failure. Luckily I wasn't going very fast. Was able to stop and investigate why my brakes failed. All brake fluid was gone. Under the drivers side the brake line failed. Fluid was dripping from a rusted brake line. This truck was garaged when not used and has not been exposed to salty roads. I have been driving for nearly 60 years and never had a brake line failure. GM should be held responsible for the poor design and repair. I see from the internet I am not the first to complain, I can't understand why the government hasn't forced GM into a recall for this serious safety problem.

Brake line corroded, causing loss of brake fluid, and subsequent brake warning light. Driver rear brake line corroded with leak in 90 degree bend. 2nd brake line later failed catastrophically, causing all loss of brake control and requiring replacement of all brake lines on vehicle.

Was backing into my driveway and all of a sudden my brake pedal went to the floor and I could hear a noise like water running. I looked under my truck and saw a puddle of brake fluid on the ground. Turns out my brake line let go. I took it to a mechanic and all the brake lines were badly corroded and have to be replaced. I also tried to use my emergency brake and the brake cable snapped from also being corroded. I don't live near salt water or anything. I'm just glad this happened in my driveway and not at high speeds or it could have been a lot worse.

The contact owns a 2001 GMC Sierra 1500. While driving approximately 5 mph in a residential driveway, the brake pedal was engaged when suddenly the pedal traveled to the floorboard abnormally. After several attempts the vehicle finally came to a stop. The contact noticed brake fluid leaking onto the ground. The vehicle had not been diagnosed or repaired. The manufacturer was not notified of the problem. There was an open and closed investigation pertaining to the Sierra model under NHTSA action number: PE10010 (service brakes, hydraulic:power assist:hydraulic:hoses, lines/piping, and fittings). The VIN was unavailable. The approximate failure mileage was 131,000.

While traveling at about 40 mph on flat paved road the brake warning light came on. When I tested the brake, the pedal went to the floor. The warning light went off then flashed back on. On the second or third pump the warning light did the same thing. At that time I had regained a very soft and little brake. Upon inspecting the brake system it was found that the brake line aft of the left front wheel, behind the inter-fender cover where it passes over the frame member had failed due to serious rusting and had burst.
