Failure Date: 12/11/2014

While having my vehicle check over for the winter, the mechanic inform me that the front brake lines are very rusty as well as the fuel lines and the cooling lines going to the transmission. This situation is very disturbing since I have very low mileage. The tubing used for the brake as well as the fuel lines should be able to withstand rusting for the life of the vehicle. If the material used by gm was not up to specification as far as corrosion protection either compensation to repair it is in order a recall should be made.

I started smelling gasoline and found a corroded fuel line at the junction between the nylon line leading from the fuel pump to the steel line going to the fuel filter. Doing repairs, the hard brake line leading from the abs unit under the driver's seat area to the rear flex line connector was leaking badly as well at the rear-most fitting. Purchasing these lines separately cannot be done, so I'm replacing all of the fuel/brake lines myself. I'm using stainless tubing for the brake lines not provided by factory gm parts.

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??.

The contact owns a 2001 GMC Sierra 1500. The contact stated that while driving 20 mph, he applied the brakes and the pedal depressed to the floor. The vehicle coasted to a stop. The contact examined the master cylinder and noticed that all the brake fluid leaked from the vehicle. The contact also noticed that the brake lines were fractured. The vehicle was towed to an independent mechanic and was not repaired. The manufacturer was made aware of the failure and offered no assistance. In addition, the contact stated that he replaced the fuel lines and pumps in the past due to corrosion. The failure and current mileages were 150,000.

I noticed a strong odor of gas coming from under the truck. I only noticed the fuel leaking when the truck was on a downhill grade. I climbed under the truck to see where it was coming from. It turns out that the fuel leak is coming from the return line on the frame under where the fuel filter is attached. That section of the fuel line is totally corroted and fuel is slowly dripping from it. I am taking it to my mechanic tomorrow for repair. The brake line right above the fuel line is also severly corroted. Gm really needs to recall and fix these issues due to these corroted fuel and brake lines. I will never buy another gm product again.

A brake line burst underneath the truck when I applied the brakes with substantial pressure (not enough to engage abs on the dry pavement). Was able to swerve to avoid vehicle that cut us off and use emergency brake to slow/stop vehicle in a safe place. All brake lines were severely rusted/corroded and needed to be replaced. Fuel lines were replaced as well at the same time, due to severe corrosion.

I’m going to list every safety defect with my 1996 GMC sierra since I purchased it used in 2008. When I first bought it I heard a swishing sound in the heater core and the airbag light was illuminated in the instrument panel, but I thought it was just low on anti freeze and that my repair facility could fix the air bag; but as it turns out the clock spring in the steering wheel was bad and I couldn’t afford to get the air bag fixed. The swishing sound was caused by air in the cooling system due to a leaking intake manifold gasket; it had to be replaced for 600. 00 $. A brake line rusted out (yes I know it’s an old truck), the fuel lines are rusting and will have to be replaced soon, and the oil cooler lines are leaking because gm vehicles have fluid lines that are prone to failure. The wind shield wipers don’t always turn on when it’s raining because of cracked solder joints in the control module and I replaced a heater/fan motor. I pulled my abs fuse and disabled the system because my abs was activating on dry pavement at low speeds and causing an increased stopping distance; a real danger in parking lots where a child could run out in front of my truck. I don’t have a grand to replace rusted hubs and sensors to make my abs work again. The drivers side cast metal door handle broke and I replaced it myself with a dealer part for 80. 00$ one would hate to be in a wreck and have the handle fail when that door is the only exit in an emergency! i’m on my third fuel pump and forth fuel pump sending unit which is the reason why i’m writing this complaint. My truck could stall out in traffic at any time and I no longer feel safe or confident driving it; I feel it’s a bad design and a safety issue. The pump and sending unit are in the fuel tank, which in an inconvenient location at best. I can’t spare 500. 00 or 600. 00 every year or so to have new components installed in my gas tank, if you want to buy an old gm or chevy truck…. . You’ve been forewarned!.

I have a 2000 GMC sierra that had brake line rust through causing brake failure. I got under the vehicle to try and change the line and found all the lines are severely rusted as is the fuel lines. Yes my truck is old and I live in the rust belt of n. Y but something needs to be done either n. Y stop using salt or the vehicles need to be built with lines that don't rust out. This issue I think is a safety issue that would be easily fixed by either no more salt or better line in the vehicles that don't rust through.

Severe corrosion of the brake lines became apparent during a sudden application of the brakes which caused multiple brake lines to rupture and leave the vehicle with no brakes since a line from the master cylinder to the abs unit front left input and the abs to the rear t line blew simultaneously. When removing the damaged brake lines they literally crumbled to pieces due to corrosion. During the repair to the brake lines severe corrosion was noted on the fuel lines also.

Driving 2006 GMC sierra pick up in utah on hwy 191 in a cross country move and pushed off the road to the side by a trucker franticly telling me to run from the truck,it was on fire. Local fire department concluded their investigation that it was the fuel line leaking as cause of origin. Also state highway patrol concluded the same at a later date. I submitted a claim for the contents to gm and was lied to for 2 months before them saying it was not their fault. They investigated the vehicle without consent from state farm. The only consent was to photograph. They spent 3. 5 hours completely investigating with no supervision. The woman handling the claim at gm said to me at the end that quote "sometimes they step up to the plate and sometimes they don't,sorry" and denied the claim. Now they refuse to speak to me or release their report so I can retain an attorney. They have lied and cheated through this whole process with other burned late model gm pu's are burned right next to mine in that yard. The truck has been stolen from, rifled through,a nd compromised by rain and gm. Now it is finally shrink wrapped in plastic and waiting for the next step. Please help as soon as you can by investigating this. Thank you.
