Letter from senator on behalf of constituent re problems with 2005 Chevy Silverado. Dot/I#2010-1208. The consumer stated his vehicle has severe corrosion on the frame. Within two yeas, the entire undercarriage had corroded, which caused the brakes and power steering to fail catastrophically. The consumer sued alleging breach of warranty. The case was heard, however GM experts testified that the corrosion was caused by sea air and they were not under any obligation to cover corrosion caused by the environment. They also testified that the corrosion was primarily cosmetic and that the vehicle was in good driving condition. The consumer stated two days later, as he attempted to drive the vehicle to a repair shop, the brake lines ruptured and the drive shaft sheared in half, nearly causing a major accident.

When the temp outside is about 40 degrees or cooler, something under the vehicle rattles(driver front). This rattling is metal on metal, and sounds like rapidly banging 2 steel cans together. The noise dissipates after driving the vehicle for about 10 minutes, but is quite noticeable when going over bumps in the road during the first 10 mins of usage.
