I had a strange one today.. I parked the car up, and locked it... then a few minutes later I had to go back, so I unlocked it.. then locked it again.. and when I locked it, the indicators didn't flash. Tried a few more times, each time they would flash for unlocking but not for locking. I checked all the doors, none were ajar and they were locked, so I didn't worry too much. The MFD showed all doors closed as well.

Drove around for about 90 minutes, parked up, and all back to normal..

Not going to worry about anything now, it'll tick over 120,000km tomorrow, and then is going to be quoted for the hail damage repair next week - if it's a write-off, then I won't be worrying about it.. if it isn't, but can be repaired fairly quickly, then I won't have it for a while during its repairs...
