Driving said vehicle thankfully at low speed when all of the sudden the brakes went to the floor . Pulled over at saw brake fluid . Looked under vehicle saw rotted out brake lines with a big hole in one of them and the other is just as rusted . I consider this a great safety issue . Due to it happens suddenly. Note: I saw on abc new and on the internet there is an issue with gm trucks as well. It now seems its not just trucks. I keep my car in great shape and have it serviced at the dealer and never was informed of a problem with my brake lines. Thank-you for your time.
