Hi! New to this forum but super frustrated with all mechanics at this point. My car never has issues starting until it gets cold. Mornings when it is 20 and below it will not start. This started happening last winter. I got a new battery last winter but the issue still kept happening. When I insert the key everything turns on, besides the car. As soon as I connect the jumper cables the car starts right away. I had to get the car towed twice last winter, still no one car figure out what is wrong with it. Please help!
