Saab 9-5 OG Problems by Year

The Original Generation Saab 9-5 was the brand's flagship executive car, renowned for its supreme long-distance comfort, incredibly supportive seats, and potent turbocharged performance, especially in the Aero trims. In the UK, the estate versions are particularly sought after as rapid, practical family haulers that offer a left-field alternative to the Volvo V70 or BMW 5 Series. The B235 engine in early models is highly susceptible to oil starvation from sludge build-up, making meticulous service history paramount. A well-maintained 9-5 Aero is one of the best value "Q-cars" (sleepers) available, perfectly suiting drivers who cover high motorways miles.

Buying Tips for the Saab 9-5 OG

  • As with the 9-3, check for proof that the sump has been dropped to clear oil sludge, particularly on models built before 2004.
  • Inspect the Direct Ignition (DI) cassette for cracks or a burning smell, as failure will leave you stranded.
  • Listen for clunking from the rear suspension; the trailing arm bushes wear out quickly and cause poor handling and uneven tyre wear.
  • Check the automatic gearbox fluid (if fitted); it should be a bright cherry red, not brown or smelling burnt.
  • Verify the SID (Saab Information Display) screen is fully readable without missing lines of pixels.
  • Test the blend doors on the climate control; if they only blow hot or cold on one side, the plastic actuator arms have snapped.
