Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“2009 Cadillac STS lost all or most brake fluid. This car has slightly over 22000 miles. Multiple warnings on panel. Dealer found that the left rearf brake caliper was leaking fluid under pressure at the point where the brake hose connects. Caliper and hose were replaced under warranty. My concern now is that if this is a widespread problem it may cause accidents when all brakes fail with no fluid left in the master cylinder reservoir. That is a very dangerous situation and, hopefully, it is a problem that is not widespread.”
