My brake lines ruptured under the drivers seat by the abs box. i inspected all of the brake and transmission lines and they are all rusted badly and need replaced immediately. i was pulling my seadoo's when this happened and had to use the emergency brake to stop the truck. i have read a ton of the same complaints on the internet today. when is anyone going to make chevy replace all of the brake and transmission lines? this truck is only a 2003 and looks like a 1903 underneath. the whole frame and undercarriage is rusting badly. please help. thank you *tr

Gm 2004 1500hd truck: gm can't fix the reduce engine power problem. the code that they can't fix keeps saying its the throttle body sensor. i have had gm dealer try to fix what this code is telling them but still have the problem. based off research this is a major problem with many other gm truck owners. when this sensor light comes on & displays reduce engine power the truck basically shuts down. i've had this happen running in the left lane of a major hwy and almost got run over. please have gm do something about this problem because i'm sure if it hasn't killed anyone yet it will. only thing different between the toyota problem and the gm problem is one speeds up and the other slows down to 20mph. as i have stated this problem happens a lot so don't pay attention to the incident date i had to enter. *tr

below is a list of history with repairs to my truck. in march 2004 i bought a brand new 2003 chevy silverado 1500hd .first 2 yrs front rotars turned covered under warranty. then 1-21-09 front rotars and calipars replaced due to rot.1-30-09 transmission line replaced rotted.on 6-19-09 new starter. 8-29-09 rear calipers and hose rotted 35455 miles.on 9-2-09 abs sensor and left front brake hose rotted. on 8-28-10 power stering pump replaced. on 8-24-11 brake lines to abs rotted 46763 miles. 10-27-11 left rear brake line rotted 47943 miles. my windsheild washer fluid reservoir needs to be replaced leaking insrument panel shows empty. i'm having my left rear brake line replaced next week...its the only one left and i dont want to take the chance of an accident. mt mechanic states he has never seen this much rust on a fairly new vehicle. unfortunately i didnt keep records in the early years of ownership but i cant believe transmission lines,brake lines ,calipers can rot that fast. i have never had this experience with past trucks i have owned. i believe there must be some sort of factory defect that is causing this. *tt
