Montreal here... and we're heading for a ice cold week here... I noticed recently (on very cold mornings), the car struggles in starting even if I leave it plugged it overnight. At first, I assumed it was because I was using a timer and only giving it about 2hrs of warming up before using, so now...even with an overnight charge, it struggles in starting and temp gauge takes quite a while before moving up.
I will pop the hood to see if I feel anything warm... otherwise, off to the dealer.
This is my first car without a starter in over 10yrs and I regret not having one in these friggin cold winter days!
