We had remote start o. A truck once, and everytime it got down to a certain temp, the dang thing would start during the night. Not sure if it was the remote start, or some mechanism that automaticslly started the vehicle at certain low temp. First time I heard it happen, thought someone was stealing the vehicle lol.
Mine has done the same thing a few times. I started keeping the fob in a hard shell pouch designed for keeping earbuds in. That way I can’t accidentally push the buttons on it. I haven’t had it starting unexpectedly nor have I had doors opening when I don’t expect them to.
What was the brand name of the truck? The environment that a car has to operate in is very harsh and extreme. Extreme cold and extreme heat. Electronics designed without this in mind, may not operate correctly. Or poorly designed electronics will not behave properly.
