Solberg was in fifth place after Friday's initial stage.
Saturday contains eight special sections and it was already on the morning's first section, SS9 Kostanjevac, that Solberg had problems.
Exactly what happened is still unclear.
Solberg's car is reported to have stopped 3.9 km on the stretch.
The Hyundai team reports that both Oliver Solberg and Elliott Edmondson are okay.
The route was interrupted, six drivers had previously completed the route with Thierry Neuville in the fastest time.
The Belgian, who is a teammate with Solberg, had not understood what had happened.
- I saw a car but not who it was but it was on a fast game, says Neuville in the interview with WRC in the finish on the stretch.
