The problem
On certain passenger vehicles, the non-return valve May crack due to a poor weld causing a vacuum leak.
The risk
If this occurs, more brake pedal force May be required to stop the vehicle and/or May experience a rough engine idle, which could result in a crash.
The fix
Dealers will inspect, and if necessary, replace the vacuum hose. The recall began on November 29, 2004. Owners should contact Volvo cars at 1-800-458-1552.
