Top issues to watch for

The most serious Saab 900 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Structural corrosion around suspension mounting points
Classic, NG9001971–1998120k–200k miles
The load-bearing structure within 30cm of suspension and subframe mounting points is prone to severe corrosion that compromises structural integrity. This affects the areas where springs, dampers, and subframes attach to the bodyshell. MOT data shows this model fails at 18.9 times the national average for this defect, indicating a widespread design vulnerability rather than isolated cases.
What happens if ignoredStructural failure around suspension mounting points can cause loss of vehicle control and is an immediate MOT failure. Repair requires cutting out corroded sections and welding in new metal, typically costing £1,000-3,000 depending on extent. Cars with severe structural corrosion may be beyond economical repair.

Major
Power steering system leaks and pump failure
Classic, NG9001971–199880k–150k miles
The power steering system suffers from widespread seal failures in both the pump and rack, with MOT data showing this model fails at 11.7 times the fleet average for power steering malfunctions. The high-pressure seals deteriorate with age, causing fluid leaks that can lead to complete power steering loss. This is exacerbated by the system's reliance on ATF fluid which breaks down over time if not regularly changed.
What happens if ignoredComplete power steering failure makes the car difficult to manoeuvre at low speeds and in tight spaces. Fluid leaks can contaminate the environment and pose a slip hazard. Pump replacement typically costs £300-600 plus labour, while rack refurbishment runs £400-800.

Major
Excessive emissions from catalytic converter failure
NG9001994–1998150k–200k miles
The catalytic converter fails at an exceptionally high rate on high-mileage examples, with MOT data showing emissions failures at This typically occurs due to catalyst substrate breakdown from thermal cycling and contamination from oil consumption in worn engines. The narrow operating window of 1990s catalyst technology makes these units particularly sensitive to fuel mixture problems and oil contamination.
What happens if ignoredCatalyst failure results in MOT failure and prohibits legal road use. Replacement catalysts cost £400-800 plus fitting. Engine tuning problems that caused the original failure must be addressed or the replacement will fail quickly.

Major
Steering column top bearing wear
Classic, NG9001971–1998120k–200k miles
The upper steering column bearing wears excessively, creating dangerous play between the steering wheel and the column shaft. MOT data shows this model fails at 21.1 times the fleet average for excessive steering column movement. This wear develops gradually but can reach the point where steering input is not immediately transmitted to the wheels, creating a significant safety hazard.
What happens if ignoredExcessive column bearing wear creates unpredictable steering response and is an immediate MOT failure. In severe cases, the steering wheel can become detached from the column. Repair requires column removal and bearing replacement, typically costing £200-400 plus labour.
