2007 Saab 9-5 2.3L Petrol · LA07 JDU

Chronic corrosion and fluid leakage define the mechanical state of this vehicle, with a trend of worsening defects leading up to its pass on 17 September 2025. The history reveals a significant failure in August 2025 caused by excessive oil leaks from both the engine and transmission, alongside worn rear suspension bushings. While the vehicle eventually passed, the persistence of these issues as advisories suggests that the underlying leaks and suspension wear have been managed rather than fully rectified. With a recorded mileage of 154,999 miles over nineteen years, the vehicle has averaged approximately 8,158 miles per year. This consistent usage pattern is typical for its age, meaning the drivetrain and chassis have been subjected to steady wear rather than the degradation associated with long periods of standing. At this mileage, however, the wear on rubber components, such as suspension bushes and brake hoses, is expected and aligns with the failures recorded in the DVSA history. Attention must be paid to the rear suspension and braking system, specifically the lower suspension arm bushes and the ferrules of the rear brake hoses, both of which remain flagged as advisories. During a test drive, listen for knocks or clunks when traversing uneven surfaces, as these are indicative of the worn bushings. A visual inspection of the rear brake hoses is necessary to ensure the corrosion at the ferrules has not progressed to a point where structural integrity is compromised. Additionally, the recorded corrosion on the front and rear coil springs and the exhaust back box suggests a general susceptibility to rust that requires close scrutiny. The history of excessive oil leaks from both the engine and transmission is a primary concern. Even though the most recent test describes the leak as not excessive, the previous major failures indicate a history of significant fluid loss. Inspect the engine bay and the underside of the transmission for fresh oil residue or dampness. During the test drive, be alert for any smell of oil burning on the exhaust manifold and check for any erratic shifting or slipping in the transmission that could be linked to previous fluid loss.
