Two problems related to ignition switch have been reported for the 1999 SAAB 9-3. The most recently reported issues are listed below.
The contact stated vehicle stalled, and had to be towed to the dealership. The ignition cassette was replaced. The vehicle is working properly at this time.
The check engine light came on while I was highway driving; I parked the vehicle as soon as possible and didn't use it until the mechanic was available. The diagnostic test showed direct ignition failure, the part was replaced with a new part. Being a long-time SAAB owner, of several models, I am aware that certain models have associated problems, such as this part.
