I observed a large puddle of brake fluid around the front left tire. Upon removal of the wheel, I discovered a large brake fluid leak at the interface between the hard brake line going to caliper and the flexible line that goes to the body of the car. During removal, the interface completely failed. This is exactly the failure that was involved in recall: report receipt date: Mar 17, 2010 NHTSA campaign number: 10v105000 component(s): service brakes, hydraulic yet for some reason, this recall was limited to vehicles sold and registered in a certain number of states. This brake line obviously is failing on vehicles registered in other states. The part on my car was within several cycles of complete failure, which would have meant loss of braking and a crash. I have retained the failed part and can provide photos or make it available for analysis.
The contact owns a 2004 Cadillac Cts. When the contact turned the ignition switch, the traction control and brake warning indicators illuminated. The failure occurred numerous times. The dealer stated that brake fluid leaked into the computer, but the exact cause of the failure was unable to be diagnosed. The vehicle was repaired and the manufacturer was notified about the failure. The approximate failure mileage was 122,000.
