Question Key Fob (remote) not working in cold weather

Hi All - I have a 7 month old 2014 impreza with a weird problem. If the temperature drops cold enough over night, (in the teens) and its still in the mid 20s in the morning, the remote unlock button won't work.

If its warmer (low 20s) occasionally I can put the key on hood by the steering wheel and it will work after a push or two. If its colder, this won't even work.

I've tried parking the car in a few different places to make sure there isn't some electrical field interfering.

The key works fine if the car is warmed up, this only occurs when its been sitting a while.

I've tried both remotes - and if one doesn't work, the other won't either.

Also - the tire pressure warning light will go off until the car warms up when the remote completely doesn't work (but I've heard that's normal)

I've dropped the car off at the dealer - and the first few times it didn't stay cold enough, so the problem wasn't replicated - but they finally got it to happen. They are going to replace the "module" when it comes in - so this should solve the problem.

My concern is - is there a chance this is could be a sign of other problems? Does anyone have any idea what would cause this ( - what would cause it to become faulty, and why would really cold weather cause it to not work, but it would be fine in warm weather)?

Thanks all!

Keep the thread updated once the module is replaced.

Hopefully that solves the issue but there's no way of knowing if this could be a sign of other problems.

Default Key Fob (remote) not working in cold weather

Thanks! They're holding on to my car while they wait for the part to come in. I'll be sure to update.

Once again - if anyone has had this problem please let me know!

I had a weird problem along the same short with my '13 Focus. I had the keyless entry and push button start. When it was cold enough, I would go to open my rear hatch, it would unlock like it should when I hit the release button on hatch, but alarm would go off.

It appeared the problem traced make to the antenna not being postponed properly after my headliner was replaced. I traded the car shortly after that repair was made, so can't comment on if it actually fixed it or not.

Just keep an eye on it and stay on the dealer to get it fixed if the module doesn't do it.

Default Dealer's response

I just got off the phone with the dealer. I asked why he thought the problem would occur when its cold out - he guess is that the module's circuit board is cracked and something isn't connecting when it gets cold.

His suggestion does put me at ease a bit, since it would explain the problem and indicate that it's not indicative of a larger issue. However... its not terribly encouraging that Subaru is putting out cars with cracked circuit boards.

That said - we'll probably never know what the problem was (unless it really is something bigger that causes more problems) because the dealer isn't allowed to open to module to check - they just are supposed to swap it out and mail back the other piece. I'll push him to follow up with SOA... but really, what are the odds of hearing back?
