We have a 2013 Altima 2.5 sl. It won't start on a weekly basis. We thought it was the -15 temp but does it at 55 and 60 degrees. Dealership said we are the only ones with this problem. Car either just doesn't start or just cranks over even if you take finger off button and foot off break. Has a mind of its own. Also has the stutter in the trans like all the others I have read about. Just pissed you pay 30k for a car and it wont start and nobody wants to help. Thanx if you can help. Dana
