Found brake fluid squirting onto the ground. Had to have all the brake lines replaced due to rust behind the drivers front wheel.

NHTSA complaint #10324488, filed 2010-04, 71,000 miles“After applying pressure to brake pedal, the vehicle failed to stop and the brake pedal was to the floor. Once the truck coasted to a stop, we pulled to the side of the road and found brake fluid leaking underneath the truck. We had the truck towed to our local dealership. The dealership replaced all metal brake lines that left us with a bill of over $2,000 for parts and labor. The entire truck is in beautiful condition and rust free except for the faulty brake lines! Gm should recall this issue.”
