One problem related to automatic transmission gear indicator has been reported for the 1999 SAAB 900. The most recently reported issues are listed below.
Engine shut off while car was running three times. First two times car was idling, third time car was being driven at 60 mph. Engine shut off with no warning and would not restart. SAAB dealer claimed in the first two instances that this could not possibly happen with car running. In first instance, dealer replaced ignition switch. In second instance, dealer replaced gear position switch. In third instance, dealer replaced chafed wiring harness to passenger seat. We are not convinced that SAAB has fixed this major safety problem, and are even more worried that a chafed wire for the heated seat can cause an immediate engine shutdown on any SAAB 9-3.
