I've had the same problem as a lot of you guys on here, especially with colder temperatures lately. I stopped by the dealership after work and they were surprisingly helpful. The guy knew exactly what the issue was and I'm scheduled to have it "fixed" on Monday. I"ll let everyone know how it goes, hopefully it lasts longer than 2 weeks.
Can ask if anyone here knows what the serial number range(s) are for affected models? My dealer is trying to tell me that this TSB doesn't cover my car's VIN, yet my car exhibits this exact problem.
