2001 Buick Century
The 2001 Century has faced significant problems related to its brake hoses, lines, and fittings. Owners reported instances of brake failure due to severely corroded brake lines.

This corrosion issue posed a substantial safety risk, as drivers experienced difficulty stopping their vehicles, resulting in accidents.
Replacing the corroded brake lines was a costly endeavor, with some owners having to replace all four brake lines.
The corrosion problem, occurring in vehicles as young as three years old with low mileage, raised concerns about the materials used in the brake lines and their susceptibility to rust.
