I can't imagine leaving my sewing machine in the car for any reason. If I even need to take it in for service, it gets into the car when I do and out of the car as soon as we get there. I'd be lost without it.

Good advice! Too hot or too cold can affect the computer section of the machine!

I don't leave my sewing machine in the car but my DH left the laptop in the trunk for over a year. Surprisingly it still works. I didn't think it would after being left thru a very cold winter and a hotter than usual summer. It was in a case. I don't know if that made a difference or not.

I LOVE EACH OF YOU ANSWERS, I just don't feel safe leaving much of anything in my car, the joy ride is to common these days.
Happy sewing everyone.

Good idea and remember that computer sewing machines stuck in a "hot" trunk will ruin them too.

Ditto with the seat belt around my machine!

I had to chuckle how we care for our sewing machines.. every time we moved I never let the professional movers move my sewing machine .. it came in the car with me (no matter how full the car was with all the other junk and kids... the sewing machine was in the car!!) LOL!! hugs

Computers are affected by extreme temperatures---hot or cold. That is why computer rooms of businesses are climate controlled. (DH worked with the main frame computer at a bank for 45 years.)

On a similar note - do you have a surge protector for your computerized sewing machine? Our house got hit by lightning 3 years ago & all our electronics were ok because our tv's & computer were plugged into surge protector but not my computerized sewing machine. When I talked with the retailer I bought it from, the 1st thing he said was "How is your sewing machine?" I hadn't even thought about it. It was fine but since then I keep it plugged into a surge protector extension cord. Just a footnote, the lightning blew out a ceiling fan, a ventilation vent from the ceiling, travelled 3 floors down to the basement & blew out the entire phone system in the house. We got away very lucky as it easily could have started a fire. Never underestimate Mother Nature !!!

I believe all this to be true, but it makes me wonder what the car manufacturers do to the computers in the cars to enable them to withstand temperature extremes. They must be doing something....:confused:
