GMSA estimates that about 20 000 units of its entry-level Opel Corsa Lite models could be affected.
Some cars produced and sold between May 2005 and June 2007 have developed a problem relating to the rear window demister that may cause the glass to shatter.
This happens when a hot spot develops around the demister's terminal area, inducing stress cracks in the toughened glass.
GMSA's After Sales vice president John Astbury said affected customers would be notified in writing. Notifications have been issued and should continue for the next 30 days.
Vehicles will be subjected to technical checks and windows, where found to be defective, will be replaced at selected PG Glass outlets at no cost to the owner.
Cars produced after June 2007 are unaffected by the recall, the company said.
