4am TLC time?? (alarm)

[aktlsz]

I picked up my Passion on Friday after work. Had a blast with it! Saturday morning, however, I did not have as much fun. At 3:47am, the alarm went off. I was up for 30 mins reseting it to have it go off several mins. later. At one point, I swear it turned the alarm on itself! (had nothing to do with being 04:03AM!!! ;-) ) So, I turned the alarm off & left the car unlocked. And got some rest....

After thinking about it, I thought maybe the doors were not properly shut. There was nothing around (animals/people) that would have or should have set it off.

Then Sunday morning at 3:52, the same thing happened!! I had made sure the doors were "properly shut." So, again, I turned the alarm off & left the car unlocked.

I mentioned this to the dealer & he looked at me like I was crazy. I have neighbors who enjoyed watching me walk around my brand new smart at 4am .... The dealer said maybe the sensor is too sensitive ... YA THINK!?!?!?!? The only thing I can come up with is the driveway is an incline - one the kids like when it snows 'cause they can sled down a bit rather well.

So, has anyone else heard something like this?? When the dealer said to baby the car initially, he was referring to learning how the smart shifts ... I did not understand 4am feedings ... TLC sessions .... as part of the deal!!!!

There may be lots of causes, but the most probable could be an upside down sensor. See lots of posts on this issue at:

Hope you can give your neighbors and yourself a restful night tonight!

I see JPaul beat me to it. Until you can get to the dealership you can disable in the interior sensor. That would keep it quiet for me inbetween visits to the dealership until they figured out the issue.

I took it in and was told they think the siren is the culprit. I am not sure but the siren worked really well - too well in fact!

I am not totally clear on what they are referring to but - since there are so many electronic parts, I suspect there is a bad card/interface or connection. I am not fully convinced this is it though. I did not get the impression there was alot of time spent on the car - but I could be wrong. So I am giving the dealership the benefit of the doubt. They are a large Mercedes dealership here and live on their reputation.

The justification given was they have seen this symptom on the MBs so ... it stands to reason this may be it here. I will find out how long the "siren" replacement will take. I'm expecting several weeks (2-3).

In the meantime, I will read the other thread. An "upside down sensor" sounds to be an incorrectly wired sensor. Possible ...

Thanks!
