Saab 

For Saab:

The most common services were oil and filter changes, brake pad and rotor replacements, tire rotations, and battery issues. Cooling system repairs (radiators, thermostats, water pumps) were fairly common with age. Turbo-related maintenance (boost system hoses, intercooler components) and electrical or sensor diagnostics were also frequent, especially on newer turbocharged models. Suspension wear (struts and bushings) and occasional transmission servicing were common on higher-mileage vehicles.
