2011 Buick LaCrosse, Cadillac SRX The Problem: GM found the LaCrosse and SRX HVAC systems may have potentially faulty software in the electronic climate control module. This would lead to an inoperable climate control system, and federal statutes mandate that cars on the road must have working windshield defrosting/defogging systems, necessitating the recall order.
The Fix: Dealers will reprogram the electronic climate control module, which should hypothetically keep everything in working order.
Number of Vehicles Potentially Affected: 10,179
