Thank you Peter--on your comment that SU fixed your car. Can you provide details on that SU you are talking about? Is there a way we can tell in our vehicles if we have or need that software update? Just yesterday--I read in FB an entry from a lady that found her car dead the next day after normally using her car--she, unbeknownst to her--is thinking because she left the windows down a little. It is interesting how our minds work and start thinking on our own what it is may be causing our trouble... I am guessing she was not able to hear nor see the dash warning so that she could --as the warning suggests-- Start her car for a little while to recharge the battery. I guess the more important aspect from what you are sharing with us is the mysterious "reset" action starting the engine does--to clear that warning from keep coming on.

John et al,

I did continue having the warning, when I was washing my car this past Saturday----and BTW--This warning is not included in all the possible warnings from the owners manual ( I was able to find it) ---Also, just happen to read something quite interesting--it happenned yesterday--as I read a lady's posting from FB--One of my many groups I now belong to. She said that, because she locked her car the day before but left the windows down a little--because it was too hot. When she tried to start her car the next day--it was DEAD completely. There is a sensor called Intrussion Sensor--and according to the manual--even wind can trigger it--Really? And are in fact recommending us not to lock our cars with windows down a little---go figure.
So, they are also telling us how to disable it. My question---How do we know if our car has these sensors?

Hello everyone, here in Chile we have the same problem. Personally, I cannot even wash the car quietly without this warning appearing, even once the vehicle did not start and I had to bridge with another vehicle.

Hello Pezhan--how long do you usually take to wash your car? At least for that time you had to jump-start your car?
