While slowing down for a light on a 4 lane highway my brake lines burst in two places failed from being weaken by rust....I had no chance to stop or advert the car and crashed into and totaled a new Buick.....the driver was taken to the hospital...the front of my truck need repair....GM made the lines out of steel even thought the exhaust system and fuel line were made out of rust resistant material ( go figure)....I have my truck serviced at the local GM dealers and they never mentioned the potential hazard....when searching the internet I found that many other owners had the same experience.....I had also been on the local and national news yet GM but they never advise me of this condition, and I'm the original owner....under different circumstances it could of been much worse...my insurance went up $1000 and the agent said the break lines on her GM truck had just burst and crashed in a ditch...people are driving their cars longer and theres going to be a bad accident...I see on the net your department has been investigating it for several years, yet no action....you could at the very least advise owners of the danger....I filed a claim with GM for help in this matter and was denied because I already had the brake lined repaired....

I previously had to have the power steering cooler replaced because of leaking corroded lines. Just recently had to have trans cooler replaced because of leaking corroded lines. Mechanic said all lines underneath (brake, steering, etc) are terribly corroded and we will definitely pay attention to all corroded lines, etc in future oil change visits. The undercarriage of my truck is a corroded disaster. The rocker panels are gone. Corroded railer hitch was replaced. Luckily nothing has totally failed yet to cause an accident.
