  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

I have had some really bad mornings with this car over the last 2 years. I am a journeyman tech. I have tried everything to fix this problem. Only in cold weather -30 celcius or worse. I have the car plugged in at home. Starts no issues. I drive 2km to work, As soon as i turn it off it refuses to crank although I just drove it 2km. I assume there is some cold weather protection sensor that does not allow the car to crank. Not a battery problem or charging issue. Is there a way to force the car to crank without the use of a diag tool? It just about left me stranded at a gas station in -40 after driving it after it sat for 10 minutes and got colder it cranked and started up no problem without a boost.

My professional recommendation is take this car to a dealership for service.
