Thanks for the reply, hopefully it gets resolved!
@EdP Consider bet taken and your hand shaken. The bet is payable after a fix and the issue does not re-occur for 1 month.I'll take you up on it. Once declared "fixed" how long do you want to wait and see if it is really fixed?
Wiring that only shorts out in the middle of the night? Only in the driveway? I'm skeptical.
I had a 1970 Ford Maverick that had a horn that would start blaring in the middle of the night when the temp went below 60 or so. No matter what I did I could not get it to stop doing it so I finally put a little switch in the line to turn of the power to it at night and then when I went to drive it I would engage it. Drove the neighbors crazy. LOLWiring that only shorts out in the middle of the night? Only in the driveway? I'm skeptical.
Ha! My '73 Pinto did the same thing. The little copper strip in the horn mechanism would bend in the cold and make contact. I didn't know it was happening (in the apartment complex parking lot) until one morning I found a note from the police saying they had disconnected my battery in the night. I just bent the copper tap out a bit and it was better.I had a 1970 Ford Maverick that had a horn that would start blaring in the middle of the night when the temp went below 60 or so.

If that were true then no one could grab the code with the proper equipment. It operates on UHF and I have the equipment, it is very easy to grab the code from the key fob, even without actually using the fob and merely having it in your pocket and pressing the unlock button on the drivers door.It's digital. The frequency is irrelevant.
The possibility of 2 transmitters (key fob/garage opener), coincidentally not maliciously, transmitting the same rolling code multiple times in the same geographical area to 2 receivers (car/garage opener) repeatedly is highly unlikely. If people think this is likely they should buy a lottery ticket, play golf and stay indoors. You are more likely to win Powerball, hit a hole in one and get struck by lightning on the same day.
It is more likely the transmitter/receiver implementation was done incorrectly/poorly. For example the auto engineer may have chosen to use a byte to store/calculate the rolling code which reduces the number of possible codes to 256.
Rolling codes, implemented correctly, mitigates the risk of a replay attack (capturing current code and re-using).
The likelihood of a transmitter randomly sending the correct next rolling code accidentally consistently is VERY low.
Short of an intentional/malicious Rolljam/man in the middle type attack or poor implementation it is highly unlikely this is an RF problem.
The best way to test this is to reseed/re-sync the key fob and car. I don’t know if this is technically feasible in the G’s.
