This complaint covers my 2004 GMC Sierra 2500hd crew cab 4wd. Almost one year ago I had a main brake line blow underneath the drivers side of the truck. The line was so corroded it was no wonder. This incident happened on 9-7-10. I was hooked to my fifth wheel camper and was preparing to pull out of driveway and when I placed foot on brake to shift into drive it blew. Thankfully I was just beginning to move. I had the truck towed to my local mechanic and he replaced the line and flushed system. Now again on 8-22-11 same situation occured. The line blew in exactly the same position as first time only a different line this time. Not to mention the other corrosion on the brake calipers and hardware that rendered my rear brakes useless. Had to replace rotors and pads due to sticking brake pad wearing to point of metal to metal contact. Did I mention I purchased this truck new and it now has only 38,500 miles. Rarely does it get driven in snow and salt. I have all receipts for parts that this problem has caused me. Im just thankful that I wasnt towing as I usually do when im driving this truck. Ive talked to my local dealership don hall in ashland, ky and they cite hundreds of trucks having this same problem. When are they going to do something about this. I am a loyal gm fan but I worked at a Toyota dealership for two years selling used vehicles. I made it a habit of checking all of our gm truck trade-ins for this rust problem and they too had this. I saw even two to three year old vehicles rusted to the point of collapse. One of these being a $65000 Cadillac escalade. Appalling.
