Hello all,

Couple days ago, I opened the door and put the key on ignition but the car lost power completely.

I disconnected both sides of the battery and when i put it back, it was fine.

I figured it was my prestige alarm system. So i put it on valet mode.

Today my lights went out for a sec and vdc light came on just for a second also while i was driving.
Also the car barely moved after a stop. I stopped at a parking lot.
I saw that the shifter was ok with p/r/n/d but not showing m mode on the screen.
When i tried to start, it was cold dead. So i had to disconnect the battery again.

I have three questions about it.

1) do you have any idea about this?
2) is it my stupid alarm interfering with the whole car?
3) also my battery connectors are not super tight. I can pull them off with a very little force. Since i've been putting them on and off a lot recently. Is this the cause of the recent problem maybe?

Thank you

 

Low batteries on these cars cause extremely strange behavior. I'd have it checked, and obviously a loose battery connection is bad news.
