2001 GMC Sierra 1500 fuel system problems

Filed Dec 13, 2021 · Brakes, Fuel system · MO

Truck has just over 150k miles. Maintained well and garaged when possible. 1) Noticed a fuel smell from the driver side door area and after parking for a long weekend, a small pool of liquid formed in front of the driver side rear wheel. It was fuel dripping from the line leaving the evap canister that had rusted through. Resulted in a $600 repair to replace all rusted fuel lines so as to eliminate the risk of fire. 2) When approaching an intersection to make a left turn and slowing down the brake pedal pushes to the floor with no stopping power at all. Used the engine/trans in manual mode to slow the truck down and avoid an accident. Driver side brake lines are blown out in multiple spots near the ABS module due to corrosion. Potential cost based on research is in the $1000 ballpark. This level of rust on critical vehicle components is irresponsible and potentially deadly. GM needs to take this more seriously and realize that their cost-cutting measures are putting people and their families in grave danger.

The ABS and break system warning light has been coming on and staying on. I lost my breaks leaving a parking spot at my local walmart as I was pulling out of a parking spot! We then made appointment for the break system to be checked/repaired. The ABS control system light went off for awhile but then comes back on even after the repair of said repair to break lines. My truck also has no fuel gauge that does not work. With these issues on my vehicle makes it very scary to drive and makes driving limited. I am not able to drive my truck long distances due to concerns of safety and possibly of ABS warning light, break issues, and fuel gauge! I was driving my truck to pick one of my daughters up from school to lose power while pushing on gas then some jerking and a foul smell of rubber burning coming from the front right tire area. I then had someone look at the truck and was told that what ever it was happening that everything looked okay and it was possible just a break sticking. It has happened 3 different times. My truck still has approximately 98,000 or so miles on it. This truck also has bad corrosion on bottom baseboards of the truck. I saw below that I am asked for specific date of issues. I can not provide specific dates since there has been so many things wrong which has happened at different times.

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 own a 2001 gmc sierra 1500. I have always taken exceptional care of my vehicle. The motor has always had a knock when you start it,which devalues the truck & it also has always used oil. The rack & pinion has started leaking. I have always owned a truck & have never had a rack & pinion go out let alone at 152000 miles.it also is losing antifreeze but there are no leaks. The fuel gauge has never worked properly,now its also flashes low coolant light when its not low. I have seen numerous complaints on line concerning these same issues & lawsuits. I do not feel the consumer should be having to foot these bills. I have called gm about my concerns & they say there is nothing they can do. What can we do to get a recall for all these problems. My truck is one of the ones that have dex-cool antifreeze.

The fuel gauge began jumping from full to empty regarless of the actual amount of fuel in the tank. I took gm's recommendation to put their fuel system cleaner into the gas tank to clean the contacts on the fuel sending unit. Approximately 6 months later, the catalytic converter plugged to the point that the vehicle would not run and it had to be replaced. Now told that only way to fix the fuel gauge is to pull the gas tank and replace the sending unit. Should be a recall for this faulty sending unit and the "quick fix" that many people probably try. Approximately $400 to fix sending unit because it's built into the gas tank, and approximately $1000 to replace the catalytic converter.
