A couple of times when I've gone out to my car in the mornings, I've found my car was unlocked. I thought it was me forgetting to lock it with the key fob but it was like it this morning & I remember using the key fob to lock it.
The other problem I've been having on occasion is my car starts fine from cold, gets up to temperature & runs fine but if I turn it off & try to restart the engine while the engine say about 5 or 10 minuets later, when its still warm, it seems to take ages to restart. You can here the engine turning over & trying to start but it doesn't. It only tries to start if you push the accelerator pedal down, will it eventually start.
Also this happened on Friday where my car started fine & had been all week. drove it to a mates, so the engine got up to temperature. Left it for about an hour & went to restart it & the engine just clicked & then it started about 2 seconds later. Since then this issue hasn't happened again.
Hopefully some of that makes sense!
