The fuel line that is on top of the gas tank rotted through. The brake and transmission lines rotted and leaked. The chassis is rotting in different places I have less than 77,000 miles on it since I bought new. I have a 1969 Malibu that I've had since it was new and I keep it outside in all kinds of weather and not one part of the chassis is rotted. I don't know what kind of steel they use now to build these cars and trucks, but it should be unacceptable. I don't know the exact dates these things happened, but I do have all the repair bills for them. When the brake line rotted through I was going to the store and when I came to a yield sign the brake pedal whet to the floor. It's a good thing it happened then, because I live on a mountain and we have a road called breakneck and it is a 25% grade. It was raining the day that this happened and all I had was a little bit of foot brake and the emergency brake. I surely would have had a bad accident if I made it to that hill.

2005 Chevrolet Suburban 1500 4X4 flex fuel, 5.3L. This vehicle's instrument cluster does not work. Tachometer pegs and sticks. The speedometer is stuck at zero. This is a very serious safety concern that General Motors/GM should do a free recall for as many owners of this vehicle have the same problems. My ABS sensor light comes on and off numerous times a day, and cluster states service air bag. General Motors should also fix this for free under a recall as others have the same issue with this vehicle. My third major complaint, is the vehicle starting problem/hard start. It takes two turns of the engine for the vehicle to turn on and stay running. I have researched this on various search engines, forums, and including recall.gov. General Motors should address this issues as well under a recall. GM installed faulty fuel pumps or fuel pumps with faulty components in them. A vehicle should start with one try. I should not have to get the fuel pressure going in the on position, or crank it twice for my truck to start.

I noticed a gasoline leak in my driveway coming from under from under the 2005 Suburban. The leak was almost in the center of the vehicle. I drove the vehicle to the dealership to get the gasoline leak repaired. I was billed $2,230 to repair the gasoline leak. I was given the following description on the invoice. "tested for fuel leak found sending unit & all fuel lines leaking...". I was told that the entire fuel line system had to be replaced due to corrosion on the underside of the vehicle. I googled the corrosion problem for Chevrolet Suburban's and read several instances of brakes failing on GM vehicles due to corrosion. The brake failures that I read about were the result of corroded brake lines. To me the corrosion problem is a very serious safety issue, especially when you combine the fuel lines and brake lines into the problem. I asked the service tech about how long the new fuel lines would last. He told me about six or seven years. I asked if they used stainless steel fuel lines, and was told "no". since this appears to be a design flaw, I feel that General Motors should put out a notice to their customers, or at the very least help with the cost of the repairs. How can I let my family, or anyone else, ride in my 2005 Suburban with only 125,000 miles and a corrosion problem? while driving all I would be thinking about is that the brakes could fail at any moment, or something would fall off the vehicle due to the corrosion problem. It's time for General Motors to step up and take responsibility for the corrosion problem.

Brake and fuel lines are corroded. I learned yesterday from win kelly Chevrolet in clarksville, md that my brake lines are so corroded I should replace them immediately. Also observed were rusty fuel lines. I, and many other Suburban/Silverado owners apparently agree, that this is design flaw and should be resolved by a manufacture recall. This was my first GM product; all others were Dodge. I never had this issue with any of the 17 other vehicles I've owned over the past 34 years. If the corrosion is that bad I'd like to know why it wasn't noted in previous "bumper to bumper courtesy inspections".

Gas smell when idling....took to dealer and they found the (flexible) fuel line leaking. They showed me the problem and it sure looked like the lines were crossed when they were installed, even the mechanic said something to that nature, but I will guarantee you he would never admit that......it is going to cost me $651 to have just one line replaced............the line wore a hole thru it where the lines were crossed and rubbing on each other.

My vehicle was manufactured with a defective fuel pump. I have had nothing but problems with the fuel gauge and delayed starts. I changed the pump and noticed the original pump was missing a spring on one of the push rods. The wear and tear made the pump hang. I have the pump and photos to deliver. This pump is a flex fuel pump. There are so many posts on this delayed start issue. I have recently posted the cause of my issue. I noticed the defect immediately because I performed the repair and not the dealer. They were quick to offer me a quote for over a thousand dollars to replace a defective part.

Smelled gas in garage and moved vehicle outside garage to investigate. Found puddle of gas on garage floor where vehicle had been parked. Crawled under vehicle and found two braided fuel lines crossing each other and resting on one another. They had worn a hole in the braided fuel line and was leaking a substantial amount of fuel. Took to local repair shop for repair. Mechanic had to custom rebuild fuel line to avoid criss-cross route originally installed. Mechanic very concerned with existing design - pressurized braided fuel line was spewing fuel beneath vehicle. This appears to be a common problem as a quick search on www.aboutautomobile.com/ under "consumer complaints" finds quite a few related instances with both the 2005 Avalanche and Suburban. Reference complaint numbers: 10465537, 10402272, 10384217, 10275857, 10417685, 10373464, 10401501. I didn't search other model years.
