While having my vehicle check over for the winter, the mechanic inform me that the front brake lines are very rusty as well as the fuel lines and the cooling lines going to the transmission. This situation is very disturbing since I have very low mileage. The tubing used for the brake as well as the fuel lines should be able to withstand rusting for the life of the vehicle. If the material used by gm was not up to specification as far as corrosion protection either compensation to repair it is in order a recall should be made.
A brake line burst underneath the truck when I applied the brakes with substantial pressure (not enough to engage abs on the dry pavement). Was able to swerve to avoid vehicle that cut us off and use emergency brake to slow/stop vehicle in a safe place. All brake lines were severely rusted/corroded and needed to be replaced. Fuel lines were replaced as well at the same time, due to severe corrosion.
My 2003 GMC Sierra 1500 sle has corroded brake, transmission and fuel lines. A certified mechanic stated that they all need replaced or breakage and leakage will occur without warning causing break, transmission or fuel delivery or fire damages. Please help with this problem ASAP. 00.
