The updates are the result of poor reviews for the car following its debut in Europe earlier this year, according to Saab's global product boss, Christopher McKinnon, who spoke recently with What Car? magazine.
Top of the agenda is improving quality, with the instrument panel and other cabin parts all set to be revised to bring them on par with models from Audi, BMW and Mercedes-Benz. The solution will be to reassess component suppliers.
Most of the changes are expected to be implemented before the arrival of the Saab 9-5 SportCombi wagon version due next summer.
