I've got a 2010 Subaru Impreza with an automatic car starter that's been installed for about 3 years.

For some reason, the car has started itself twice in the past couple of hours, for no apparent reason. The fob is on my counter (i.e. no way the button has been pressed).

Is this definitely a problem with the automatic car starter, or could it be a deeper issue with the car?

Without physically seeing the car I'd be 99% certain that this is to do with the automatic starter. I've never see a car without auto-start technology do this (OEM or otherwise) and aftermarket tech that affects when a car is running, be it an auto-start, or turbo timer can be a bit temperemental.

It could be a case of moisture ingress into the control unit for the remote starter.

As Solar Mike mentions the first step is to disconnect/disable the remote starter and see if the problems persist. If the don't then you've found your culprit, and at that point I'd suggest contacting the manufacturer/installer of the remote start system.
