The vehicle's hydraulic brake lines have rapidly corroded, to the point that they may give out any day. the vehicle has been well-maintained (all service performed by a gm dealer) and has received regular undercarriage washing. in addition, the electronic brake control module (ebcm) has just failed; if a brake fluid leak occurs, there will be no warning or indication presented by the vehicle and the vehicle may not be able to stop. gm has stated that any repairs for these serious safety hazard conditions would need to be paid out of pocket, with an approximate cost of $2500. a vehicle that is less than 10 years old should not such exhibit corrosion to the point of a safety hazard. *js
