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.
The transmission/drive line shifts hard and seems to be in a bind during shifting operations. There are loud banging noises coming from the driveline/axles. There also now seems to be fluid leakage from the passenger side front axle housing. I checked the fluid level and had to add one pint of axle oil to the axle unit.
