One problem related to brakes failed has been reported for the 1999 Volvo S80. The most recently reported issues are listed below.
The information panel gives the following warnings: brake failure stop safely ASAP (t2 goes to ------) stc service required' when this happens the cruise control doesn't work. We have called the dealer to find out what to do. He says to bring the car in when the message is showing. The message comes and goes and isn't consistent enough to be able to take it to the dealer when it is on. We were told that the brakes should work without the abs feature. The dealer has moved to 45 miles from our house. We believe that this is a false warning.
