My fiance bought an 2010 SRX a while back with only 20,000 miles that was a gm executive vehicle. Long story short, it intermittently goes dead at night. It is not consistent on when it does it. What i have noticed is that if the radio doesn't work (another problem) and you shut it off that way at night, it will be virtually dead the next morning. Meaning that using the remote to start it, it will crank for a half of a second then the horn will start honking. When you get in and try the push button it says no remote detected (meaning the battery is dead). There has to be a direct correlation with the radio not working then shutting it off that makes it go dead since both seem to happen in order. The dealer in Springfield IL has seen it several times already and has done a recall or service bulletin by re-flashing or re-programming it for the problem we are having. They also paid for a new battery. But, it hasn't fixed it and they just keep saying they can't find a problem.
Has to be some kind of module problem. Anybody else heard of this problem with these things?
