One problem related to steering wheel has been reported for the 1999 Volvo S80. The most recently reported issues are listed below.
When vehicle turns left steering wheel binds up. Steering wheel does not allow vehicle to make a full left turn. While attempting to turn left, vehicle will go half way, and consumer is forced to reverse and move straight. Dealership is unable to reproduce problem, and issue a remedy. Also, consumer attempted to fill the gas tank w/ fuel when it was 3/4 of a way empty. Gas nozzle would not pump the gas as if the tank was full. So consumer pulled the fuel pump out, and fuel started to squirt out on consumer, and a puddle on the floor.
